Accompanying drawing explanation
Fig. 1 is the schematic cross sectional views of Heat-resistant laminated-positioninelectronic electronic adhesive tape used for solar batteries.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment: as shown in Figure 1, adopt the one Heat-resistant laminated-positioninelectronic electronic adhesive tape used for solar batteries that the present invention manufactures, comprise adhesive layer 1 and base layer 2, adhesive layer 1 is attached on base layer 2.
Described base layer is modified PE, comprises 80 weight part PE, the polyamide (PA) of 12 weight parts, the uvioresistant auxiliary agent titanium dioxide of 5 weight parts, the toughner EVA of 3 weight parts.Can adopt known equipment, such as Universal stirring machine, twin screw extruder, single screw extrusion machine, mill, Banbury mixer etc., perform this melt blending.
In modified PE matrix aspect, coating adhesive layer is high-temperature resistant self-adhesive silica gel.Adopt coating machine to be coated on by high-temperature resistant self-adhesive silica gel in modified PE matrix aspect, thickness is 6um.At 50-80 DEG C, use drier 10min, obtained Heat-resistant laminated-positioninelectronic electronic adhesive tape used for solar batteries.
Below embodiment is further detailed.
PE low price, have excellent resistance to low temperature (minimum use temperature can reach-70 ~-100 DEG C), chemical stability is good, and water-absorbent is little, and electrical insulation capability is excellent.PA has very high physical strength, and softening temperature is high, heat-resisting, and coefficient of friction is low, and electrical insulating property is good, has self-extinguishing, good weatherability.By PE and PA is blended, be expected to the intermingling material obtaining good combination property.When just PE and PA is blended, suitable compatilizer (or being called solubilizing agent) can be selected as required.
In an embodiment, the median size choosing uvioresistant auxiliary agent is 200nm.If the median size of uvioresistant auxiliary agent is less than 5nm, then first raw materials cost is high, and industrialization possibility diminishes, be secondly because nanoparticle itself occur reunite and be unfavorable for uvioresistant auxiliary agent and other components blended.If the median size of uvioresistant auxiliary agent is greater than 500nm, be then unfavorable for that uvioresistant auxiliary agent mixes with other components, easily have large particulate matter or block to produce.
When the content of uvioresistant auxiliary agent is by when being less than 1 weight part, uvioresistant effect is sharply deteriorated.If the content of uvioresistant auxiliary agent is more than 20 weight parts, then uvioresistant effect can not increase because content increases, and so there is no necessity and makes the content of uvioresistant auxiliary agent more than 20 weight parts.Therefore the weight part of selected uvioresistant auxiliary agent titanium dioxide remains between 1-20 part.
In an embodiment, when toughner ethylene-vinyl acetate (MAH-g-EVA) containing quantity not sufficient 0.1 weight part, then do not have toughness reinforcing effect; If the content of toughner is more than 10 weight parts, then the toughness of polypropene composition is excessively strong, does not meet the requirement to products production performance.In a preferred embodiment, the toughner that weight part is 1-15 is comprised.
Because Heat-resistant laminated-positioninelectronic electronic adhesive tape used for solar batteries according to the present invention comprises uvioresistant auxiliary agent, so when this Heat-resistant laminated-positioninelectronic electronic adhesive tape used for solar batteries will be comprised to be used in solar cell device, this member obstruction returns (such as reflect) some ultra violet rays, this some ultra violet rays can be used for the opto-electronic conversion of the cell piece in solar cell device, thus improves photoelectric transformation efficiency.
As the method for above-described embodiment, adopt the Heat-resistant laminated-positioninelectronic electronic adhesive tape used for solar batteries (as described in summary of the invention) obtained with the same or analogous structure of this embodiment or material, all within scope.
