本发明涉及一种复合制品及其制备方法。 The present invention relates to a composite article and its preparation method.
更具体地，本发明涉及一种包括对电和/或热绝缘的基材和置于此基材的每个面上的保护层。 More particularly, the present invention relates to an electrical and / or thermally insulating substrate and the substrate protective layer disposed on each face.
在电子技术领域中，电动机通常采用象聚酯膜一样的柔韧材料来绝缘，如用塑料制成的膜。 In the field of electronic technology, the motor usually used as a polyester film like flexible insulating material, such as a film made of plastic. 但是，这些膜对环境，特别是对湿气是敏感的，或者不具有足够的机械和抗热性能。 However, these films on the environment, particularly moisture sensitive, or does not have sufficient mechanical and thermal properties. 为了克服这些缺点，已有建议制备包括夹在两个由耐热纸制成的保护层之间的电绝缘层的复合材料。 To overcome these drawbacks, it has been proposed preparation sandwiched between two protective layers of paper by a heat-resistant electrically insulating layer of composite material. 这种复合材料一方面要求纸的制备包括例如切断的芳族聚酰胺纤维和芳族聚酰胺的类纤维，另一方面，为了使层之间具有良好的粘接性，要求将纸以连续的方式用于电绝缘支撑层。 Preparation of such a composite sheet material comprising e.g. ask the chopped aramid fibers and aramid fibers, on the other hand, in order to make a good adhesion between the layers, require a continuous paper way for electrically insulating support layer. 这种制备复合材料的方法比较复杂。 This method for preparing a composite material is more complex. 另外，这种保护纸层的特别是与湿气有关的严密性不好。 In addition, this special protective paper layer is closely associated with the moisture is bad.
另外，也可将电绝缘基材，尤其是电绝缘柔韧膜用于软性印刷电路的生产。 In addition, also be an electrically insulating substrate, in particular for the production of electrically insulating flexible film of the flexible printed circuit. 这些制品是通过金属化膜的一个面，优选两个面，接着通过采用例如金属化层的化学浸蚀方法生产电路而制得的。 These articles by a metalized film surface, preferably both surfaces, followed by chemical etching using, for example a process for producing a circuit metallization layers and the obtained. 电子元件如晶体管、二极管或电容器是例如通过镀锡被焊接到这些电路上。 Electronic components such as transistors, diodes or capacitors, for example by being soldered to the tin these circuits.
这种支撑膜必须具有良好的形稳性，特别是在焊接温度下。 This support film must have good dimensional stability, especially at soldering temperatures. 由于这些原因，聚酯膜逐渐地被由具有改进了抗热性和形稳性的塑料如聚酰亚胺或聚芳族聚酰胺树脂制成的膜取代。 For these reasons, a polyester film is gradually improved membrane having heat resistance and dimensional stability of plastics such as polyimide or aramid resin substituted. 但是，生产这些塑料的成本很高。 However, the high cost of production of these plastics.
本发明的一个目的是通过提供一种对热和电绝缘的复合材料而克服这些缺点，这种复合材料包括特别是对湿气不透的保护层，并且可以通过简单使用方法制得。 An object of the present invention is achieved by providing a thermal and electrically insulating composite material which overcome these shortcomings, the composite material comprises particularly to moisture impervious protective layer, and may be obtained by simply using the method. 这种材料可以作为对电绝缘的基材，在通过采用铜层或金属化工艺将金属层沉积于这种复合材料的至少一个面上之后，用于软性印刷电路的生产。 This material can be used as the electrically insulative substrate, after passing through the copper layer or metallization process a metal layer is deposited in such a composite material is at least one surface, for the production of flexible printed circuits.
为此，本发明提供一种复合制品，其中包括一个连续的支撑层和置于这种支撑或基材层至少一个面上的保护层。 To this end, the present invention provides a composite article, which comprises a continuous support layer and such a support or base layer disposed at least one surface of the protective layer.
根据本发明，至少一个保护层是由耐热树脂制成，这种树脂包括被栽绒入支撑层或基材表面的由耐热材料制成的增强纤维。 According to the present invention, at least one protective layer is formed of heat-resistant resin, such resin comprises reinforcing fibers are made of tufted into the support layer or the substrate surface by the heat-resistant material.
根据本发明的优选实施方案，支撑层或基材层是对电和/或热绝缘的连续层。 According to a preferred embodiment of the invention, the support layer or substrate layer is electrically and / or thermally insulating continuous layer.
由对电和/或热绝缘的合成材料如聚酯、聚烯烃、聚碳酸酯、聚苯硫、聚酰亚胺、热致变的聚酯等等制成的膜被以实例的方式提到用作适于本发明的支撑层或基材层。 By electrical and / or thermal insulation of synthetic materials such as films made of polyester, polyolefin, polycarbonate, polyphenylene sulfide, polyimide, thermotropic polyesters and the like are mentioned by way of example used as a suitable support layer or substrate layer of the invention.
由适用于本发明的耐热材料制成的纤维是例如由聚酰亚胺、聚芳族聚酰胺和聚酰胺-酰亚胺制成的纤维。 Fibers useful in the present invention by a heat-resistant material, for example, polyimide, polyamide and polyaromatic polyamide - imide fiber made.
以适用于本发明耐热树脂实例的方式被提到的是聚酰亚胺、聚酰胺-酰亚胺、聚芳族聚酰胺、双马来酰亚胺、环氧和三嗪树脂或其混合物。 Examples of suitable heat-resistant resin in the present invention is the manner mentioned polyimide, polyamide - imide, poly aramid, bismaleimide, epoxy and triazine resin or a mixture thereof .
更有利的是，适用于本发明的树脂是能够以溶液的形式被沉积在栽绒了纤维的层之上的树脂，树脂可以通过与第三种溶剂根据凝结工艺进行溶剂交换，或通过例如以凝胶形式的沉淀作用，或通过溶剂的蒸发而被沉淀。 More advantageously, the resin suitable for the present invention is the ability to be deposited in the form of a solution of the tufted fiber layer above the resin, the resin can be by solvent exchange with a third solvent according to congeal process, or by e.g. precipitation in gel form, or is precipitated by evaporation of the solvent.
可被特别提及的树脂优选是：聚酰胺-酰亚胺和特别是那些通过二异氰酸酯如甲苯二异氰酸酯、4，4'-二苯基甲烷二异氰酸酯、二苯基醚4，4'-二异氰酸酯、间亚苯基二异氰酸酯、1，6-六亚甲基二异氰酸酯、双环己基二异氰酸酯等等，在存在或不存在芳香二酸如间苯二酸或对苯二酸情况下，与一种酸酐如1，2，4-苯三酸酐或一种二酸酐和1，3-二羧苯磺酸酯反应制得的树脂。 Resin preferably may be mentioned in particular are: polyamide - imide, and especially those obtained by diisocyanates such as toluene diisocyanate, 4,4'-diphenylmethane diisocyanate, 4,4'-diphenyl ether diisocyanate, m-phenylene diisocyanate, 1,6-hexamethylene diisocyanate, dicyclohexyl diisocyanate and the like, in the presence or absence of an aromatic diacid such as isophthalic acid or terephthalic acid under the conditions, and a kinds of acid anhydride such as trimellitic anhydride or a diacid anhydride and 1,3-dicarboxylic acid ester resin obtained reaction.
根据本发明的另一个特征，根据常规栽绒技术将栽绒纤维置于支撑层或基材层之上，也就是说，通过用粘接剂涂覆有待被栽绒的表面，基本上保持相互平行和与待栽绒表面垂直的纤维层的沉积是通过例如电场作用而被栽绒的。 According to another feature of the invention, according to conventional techniques tufted tufted fibers are placed on top of the supporting layer or the base layer, that is, by using an adhesive coating is to be tufted surface, remain substantially mutually deposition and to be parallel and perpendicular to the surface of tufted fiber layer by, for example electric field was planted velvet.
可被提及的适用于本发明的粘接剂是耐热性粘接剂，例如由Henkel公司出售的聚酯/聚氨酯型的双组份粘接剂。 May be useful in the present invention the adhesive is mentioned heat resistant adhesive, such as sold by Henkel polyester / urethane type two-component adhesive.
在本发明的一个实施方案中，纤维可以具有不同的或相同的长度。 In one embodiment of the present invention, the fibers may have different or the same length. 纤维的长度和栽绒层的密度是根据复合构件的性质和用途，例如根据所需保护层的厚度和表面性质来确定。 The length and density of the layer of tufted fibers according to the nature and use of the composite member, e.g., determined according to the desired thickness and surface properties of the protective layer.
特别是由于栽绒纤维的存在，这样形成的保护层是连续的并具有良好的机械性能，在涂料用树脂的凝结和沉淀作用下，栽绒纤维可以在支撑层上被压平而形成一个增强的保护层。 In particular, since the presence of tufted fibers, the protective layer thus formed is continuous and has good mechanical properties, in the coagulation and precipitation of coating resin, the tufted fibers can be flattened on the support layer to form a reinforced The protective layer.
在本发明的另一实施方案中，对这样形成的复合材料进行后处理，其中特别包括为了使保护层发挥所需的作用而使其成型，在保护层的表面加压。 In another embodiment of the present invention, after the composite material thus formed is treated, including, in particular in order to make the protective layer plays the desired role and to shape, in the surface protective layer of pressure. 这种处理也可以采用轮压的形式，这样可以使保护层的表面和复合材料的厚度具有均一性。 Such treatment may also be employed in the form of wheel pressure, this could make the surface and thickness of the composite material having a protective layer uniformity.
本发明的材料具有良好的粘接性，尤其是将涂料用树脂粘接到支撑层表面的粘接性，这种粘接由于栽绒纤维的存在而得以提高和增强。 Material of the present invention has good adhesiveness, especially the coating resin layer is adhered to the adhesive surface of the support, due to the presence of such adhesive and the tufted fibers can be improved and enhanced.
另外，这种保护层的粘接性通过限制将支撑层如聚酯膜暴露于环境气氛如湿气、辐射等等，而可以提高复合材料的抗老化性。 Further, this protective layer adhesion to the support layer by limiting such as a polyester film is exposed to the ambient atmosphere, such as moisture, radiation, etc., and can improve the aging resistance of the composite material. 这种支撑层的绝缘性质因此而长时间保持在令人满意的水平。 The insulating nature of the support layer thus long maintained at a satisfactory level.
进一步说，涂料用树脂的采用允许将大量的添加剂如防水化合物、润滑剂、色料等等加入到栽绒的保护表面。 Furthermore, the use of coating resins allow a large number of additives such as waterproof compounds, lubricants, pigments, etc. is added to protect the surface of tufted. 这些添加剂可以改善复合材料的性能和外形而用于所需用途。 These additives may improve the performance and appearance of the composite material was used in the desired application.
因此，在将本发明的复合材料用作金属层，特别是用于生产软性印刷电路的支撑层的情况下，这种涂料用树脂可以包括填料，如金属氧化物类，例如氧化亚铜，来对保护层的表面进行金属化处理。 Thus, in the case where the composite material of the present invention is used as a metal layer, in particular for the production of flexible printed circuit supporting layer, this coating resin may include fillers, such as metal oxides, for example cuprous oxide, to the surface of the protective layer metallization processing.
本发明的一个主题特别是结构如上所述并且在其至少一个面上有一个金属层的复合材料。 A subject of the present invention constructed as described above and in particular on at least one surface thereof a composite metal layer. 这种金属层可以通过任何已知的沉积金属的技术沉积在塑料层的表面上。 The metal layer may be deposited by any known technique of metal deposited on the surface of the plastic layer. 一个可以提及的又不暗示限定的实施例是通过在复合材料表面的粘接，或者优选的通过电解和/或电化学的金属化方法形成金属层，而施加金属片如铜的技术。 A may be mentioned without implying embodiments are defined by a metal layer formed on the bonding surface of the composite material, or preferably by electrolytic and / or electrochemical metallization method, a metal sheet such as copper is applied techniques. 实际上，由于可以往涂料用树脂中加入金属化前体添加剂，本发明的复合构件能够简化金属化工艺的运用，如在法国专利2518126中所述的。 In fact, since it is possible to add a metal coating resin precursor additives, the composite member of the present invention can simplify the application of the metallization process, as described in French Patent 2,518,126.
简单的说，在此法国专利中所述的金属化工艺包括往要被金属化的基材中加入能够增加用于金属工艺的表面的金属底漆涂区的填料。 Simply put, in this metallization process described in French patent comprises adding a filler to be added can be used to increase the surface of the metal coating process of the metal primer region metalized substrate. 适用的填料尤其是指非导电性的金属氧化物如氧化铜。 Suitable fillers particularly refers to non-conductive metal oxides such as copper oxide. 将基材的表面用能够将上述金属氧化物还原成可导电的金属的还原剂，如氢硼化物处理。 The surface of the substrate with the metal oxide can be restored so as to be electrically conductive metal reducing agent, such as borohydride treatment. 这种还原的金属形成了与可采用通过电解和/或电化学途径直接金属化相适应的金属底漆涂区。 This reduction of metal and can be formed by electrolysis and / or electrochemical pathways direct metallization adapt metal primer coated area.
本发明的金属化复合材料最适用于一种软性印刷电路的生产，因为整个单元即使在焊接温度都具有良好的形稳性，而不管支撑膜的性质如何。 Metallized composite material of the present invention is most suitable for the production of a flexible printed circuit, because the whole unit even at soldering temperatures have good dimensional stability, regardless of the nature of the support film. 实际上因为保护层是用耐热材料制成的，就防止了支撑膜的收缩。 In fact because the protective layer is a heat-resistant material, is prevented shrinkable support film. 这就能够采用不必具有良好的与温度有关的形稳性的支撑膜，如聚酯膜。 It is possible to employ not have to have good temperature-related dimensional stability of the support film, such as polyester film.
进一步说，本发明的构件具有良好的抗老化性，这就使印刷电路可长时间或在不利的环境下使用。 Further, the member of the present invention have good aging resistance, which makes the printed circuit may be used in a long time or under adverse conditions. 最后，在基材的两个面之间的电绝缘性得以提高。 Finally, between the two faces of the electrically insulating substrate is improved.
本发明的另一目的是一种生产上述复合材料的方法，包括：一将一层栽绒纤维沉积在对电和/或热绝缘的支撑层的至少一个面上，所述的纤维是由耐热纤维组成的，和-用耐热树脂涂覆栽绒纤维，形成对绝缘支撑层的保护层。 Another object of the present invention is a method for producing the above composite material, comprising: a layer of tufted fibers deposited on the electrical and / or thermal insulation of at least one surface of the support layer, wherein the fibers are made resistant Hot fiber composition, and - with a heat-resistant resin-coated tufted fibers formed on the insulating layer, a protective layer support.
根据本发明的一个特征，栽绒层的涂覆是在树脂溶液中进行的，树脂是被沉积到栽绒纤维的层之上和/或之中以制得被纤维增强的树脂层。 According to one feature of the invention, the coating layer is tufted in a resin solution for the resin is deposited on top of the tufted fiber layers and / or being to produce a fiber-reinforced resin layer being.
树脂的沉积尤其可以认为是这样的技术，即能够将树脂溶液沉积在栽绒层上，并使此层与一种不溶解树脂的液体接触，例如将此构件浸在非溶剂液体中；这种技术叫做凝结作用。 Deposition of the resin can be considered in particular such a technique, i.e., the resin solution can be deposited on the tufted layer, and this layer is contacted with a liquid that does not dissolve resins, for example, this member is immersed in a non-solvent liquid; this technique is called coagulation.
但是，其它能够使树脂沉淀或凝结的技术也可在不超出本发明范围的情况下被采用。 However, other resin can be precipitated or coagulated techniques may also be without departing from the scope of the present invention is employed.
接着将复合构件干燥以去除溶剂或非溶剂。 The composite member is then dried to remove the solvent or nonsolvent.
通过树脂凝结作用来涂覆栽绒纤维导致下列事实成为可能：在凝结作用的过程中，用对树脂是非溶剂且具有适当低沸点的其它化合物如水来替代通常具有高沸点的树脂溶剂。 Coated by the resin coagulation tufted fibers causes the following facts became possible: the coagulation process, other compounds with the resin and having an appropriate non-solvent such as water to replace the low boiling point solvent is usually a resin having a high boiling point. 这样复合构件的干燥就可以在较低的温度下进行，减小了破坏支撑膜的危险。 Such drying of the composite member can be carried out at lower temperatures, reduces the risk of destruction of the support film.
根据本发明的实施方案，涂覆溶液中树脂的重量含量在5％和50％之间。 According to embodiments of the present invention, the weight content of the resin in the coating solution of 5% and 50%.
适用于本发明的溶剂是，例如N-甲基吡咯烷酮、二烷基脲如二甲基亚乙基脲(DMEU)或二甲基亚丙基脲、二甲基乙酰胺、二甲基甲酰胺、酮类、二甲基亚砜和它们与其它惰性溶剂如二甲苯、二甲基醚或二甘醇或三甘醇的混合物。 The solvents useful in the present invention are, for example N- methylpyrrolidone, dialkylureas such as dimethylethyleneurea (DMEU) or dimethylpropyleneurea, dimethylacetamide, dimethylformamide , ketones, dimethyl sulfoxide and their other inert solvent such as xylene, diethylene glycol dimethyl ether or triethylene glycol or mixtures thereof.
树脂的凝结作用通常是通过将被树脂溶液涂覆的栽绒层与水接触而进行的。 Coagulation resin is usually the resin solution was applied by the tufted layer in contact with water carried out.
树脂溶液可以含有能够改进湿润栽绒纤维能力的添加剂。 Resin capable of improving the wetting solution may contain fibers tufted ability additives. 但是，为了提高纤维在树脂中的湿润性，它们可以用能够调节表面张力的涂饰剂处理。 However, in order to improve fiber wettability of the resin, they may be treated with a finishing agent capable of adjusting the surface tension.
在干燥后，本发明的复合构件具有良好的粘接性。 After drying, the composite member of the present invention has good adhesion.
