Description
Technical field
The present invention relates to a kind of manufacture method of acrylic ester emulsion, especially a kind of acrylic ester emulsion manufacture method that is used for the phosphoric acid ester group of anticorrosive coating.
Background technology
At present, in the anticorrosive coating field still based on solvent based coating, but because the solvent of coating is volatile, caused to the pollution of environment with to the harm of HUMAN HEALTH, wasted the energy that derives from oil, along with the enhancing of people's environmental consciousness, the Water-borne modification of solvent based coating more and more becomes a urgent task.
In watery anti-corrosion paint, when 1. the use Synolac is as the film forming matter base-material, its drying principles is that the two keys on the Synolac carry out oxidation cross-linked in air, because of speed very slow, need to add siccative, and the dryness of urging of siccative can be subjected to the influence of water and paint filler, and rate of drying is often undesirable; When 2. use Resins, epoxy is as the film forming matter base-material, need to add solidifying agent, and often to add an amount of hydrophilic solvent, to guarantee that resin can be dissolved in the water, so must add solidifying agent before use in proportion, the problem that also has simultaneously working life use inconvenience, and hydrophilic solvent also has certain influence to environment; When 3. using the bi-component acrylic emulsion, exist equally and use preceding adding solidifying agent and the problem of working life, and its solidifying agent---therefore easy the and water reaction of hydrophilic isocyanate exists the more problem of side reaction as the film forming matter base-material.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of and contain bound phosphate groups in the molecular structure of acrylic ester emulsion; make emulsion in film process; bound phosphate groups can form fine and close phosphate coating with the ground metal; make the metallic surface that passivation take place; can prevent water molecules and other salt ions and metallic contact; so have antirust function, and can be used for the acrylic ester emulsion manufacture method of the phosphoric acid ester group of anticorrosive coating.
For solving above technical problem, the technical scheme that is adopted is as follows:
A. fill a prescription:
Acrylate monomer: account for 80%～99% of polymerization single polymerization monomer total amount;
The acrylate monomer of phosphoric acid ester group: account for 1%～20% of polymerization single polymerization monomer total amount;
Emulsifying agent: account for 3%～10% of polymerization single polymerization monomer total amount;
Water soluble starter: account for 0.2%～1% of polymerization single polymerization monomer total amount;
Deionized water: account for 50%～70% of product population;
B. technical process:
At first the acrylate monomer of acrylate monomer and phosphoric acid ester group is mixed into polymerization single polymerization monomer and standby → then thermometer is being housed, stir, add deionized water and emulsifying agent in the reaction vessel of reflux, open to stir and be warming up to 70～90 ℃ → again in the reaction vessel 30%～40% of 10%～15% and water soluble starter of adding polymerization single polymerization monomer, and be incubated 70～90 ℃, after finishing → treat the insulation end in 30～60 minutes, remaining water soluble starter is dissolved in the deionized water of set amount, and in 2～3 hours, evenly add respectively in the reaction vessel with remaining polymerization single polymerization monomer → after adding, still keep 70～90 ℃ of temperature, promptly finish the synthetic of emulsion of the present invention after 2～3 hours.
Owing to adopted above technical scheme; the effect that produces is conspicuous: owing to contain bound phosphate groups in the emulsion molecular structure; so emulsion is in film process; bound phosphate groups and ground metal have formed fine and close phosphate coating; make the metallic surface that passivation take place; can prevent water molecules and other salt ions and metallic contact, make this emulsion have good corrosion proof function.With the anticorrosive coating of emulsion of the present invention as the film forming base-material, it is in drying process, only need moisture evaporation to get final product, need not oxidation drying, rate of drying is accelerated greatly than water alcohol acid anticorrosive coating, also need not add solidifying agent, before construction, need not to carry out weighing and calculate the consumption of solidifying agent, very easy to use, there are not the working life after solidifying agent adds and the problem of side reaction yet, as apply the present invention in the anticorrosive coating, certainly will have good corrosion proof function.
