Abstract
A preparation process of silicon acrylic acid coating relates to a preparation process of coating, providing a preparation process of silicon acrylic acid coating which has high hardness and abrasion resistance, and can be used to on surface coating of plastic rubber and wood-ware. The preparation process comprises firstly adding toluene or isobutyl alcohol or the mixing solution of both into a reactor, and stirring and heating to reflux, secondly mixing acrylic esters monomer and acrylic ester monomer which comprises epoxy radical, then adding initiating agent whose weight is 0.1%-10% of the weight of monomer, stirring to dissolve and mix evenly, thirdly adding mixed monomer solution in the second step into the reactor in the way of one-time adding or dripping, keeping warm for 2-3h, and obtaining acrylic acid resin after stopping reaction, and fourthly mixing acrylic acid with curing agent, and evenly stirring to use.
Description
Technical field
The present invention relates to a kind of preparation method of coating, especially a kind of preparation method who is used for the novel high-energy silicon-acrylic coatings of plastic cement, woodenware.
Background technology
Because electronic industry fast development in recent years, and it is more and more higher to the demand of house fitting-up condition, the topcoating that requirement is used as these products has various more superior rerum naturas, and therefore developing the high-performance coating that meets social desirability is modern coating developing direction.The high-performance of coating comprises high-decoration, high preservative property, super weather resistance, multifunction and good performances such as application property.The electronic product sealer adopts esters of acrylic acid plastic cement lacquer basically at present, though its gloss is beautiful, fastness to rubbing is lower.Because wear resistance is not enough, top coat just is worn in the short period of time and fades, and until show-through, loses original color and luster and aesthetic feeling, also causes the product minimizing in work-ing life simultaneously; And the use of electronic product is generally at several years and even many decades, thus electronic product and most of be that the product of shell is badly in need of wearing face coating with the plastic cement.
Acrylic resin has high reaction activity and high, and therefore good stability to hydrolysis and light stability are a kind of protection of electronic product casing and coating types that woodenware beautifies of being widely used in.But esters of acrylic acid coating on its chemical constitution, can not have good wear resistance, can't satisfy the service requirements of high-wear resistance.Along with the development in market, the user is more and more higher to the requirement of product, and corresponding producer is also more and more stricter to the performance requriements of coating, therefore how to improve the important research direction that the plastic coating performance has become present coating material.
Summary of the invention
Purpose of the present invention is intended to provide a kind of have high rigidity and wear resisting property, can be used for the preparation method of the silicon-acrylic coatings of plastic cement, woodenware external coating.
The preparation method of described silicon-acrylic coatings is as follows:
1) toluene or isopropylcarbinol or the mixing solutions of the two are joined in the reactor, be heated with stirring to backflow;
2) acrylic ester monomer and the acrylate monomer that contains epoxide group are mixed, the initiator that adds monomer total mass 0.1%～10% then, stirring and dissolving, mix, by mass percentage, acrylic ester monomer: the acrylate monomer that contains epoxide group is (80%～99%): (1%～20%);
3) mixed monomer solution in the step 2 is added in the reactor in the mode of disposable adding or dropping, insulation 2～3h, stopped reaction gets acrylic resin;
4) acrylic resin is mixed with solidifying agent, stir, can use, by mass percentage, acrylic resin: solidifying agent is (5～25): 1.
Described acrylic ester monomer is at least a in vinylformic acid, methacrylic acid, butyl acrylate, methyl acrylate, methyl methacrylate, n-BMA, Propenoic acid, 2-methyl, isobutyl ester, 2-ethylhexyl methacrylic ester, methacrylic acid moon silicon ester, methacrylic acid benzyl ester, cyclohexyl methacrylate etc.
The described acrylate monomer that contains epoxide group is a glycidyl methacrylate, at least a in the methyl propenoic acid glycidyl ether etc.
Described initiator is preferably benzoyl peroxide etc.
Described solidifying agent is preferably quadrol, γ-An Bingjisanyiyangjiguiwan or diethylamine etc.
Rate of addition in the step 3) is preferably 0.5～1h/50g.
The mixing solutions of toluene and isopropylcarbinol can be arbitrary proportion.
The mixture of glycidyl methacrylate and methyl propenoic acid glycidyl ether can be arbitrary proportion.
The present invention is from functional group reactions mechanism, cut out by molecular designing and molecule, on original acrylate backbone, increased an active functional group-epoxide group, and and be with the combination of amino class solidifying agent, design a kind of bi-component acrylic ester coating, it is good that it has the acrylate resin weather resistance, cohesiveness is good, advantages such as good decorative property, product is after spraying, will be by epoxy and the amino chemical crosslink reaction that takes place, wear resisting property is considerably beyond the esters of acrylic acid coating of the single component of same molecular amount, simultaneously in alcohol resistance, coating fundamental property aspects such as hardness all are greatly improved.And preparation technology is simple, can on original coating apparatus basis, produce, and be a kind of at higher coating varieties of professional price ratio such as plastic cement, woodenware.
