Abstract
The composition of monocompount hydroxy acrylic acid coating is composed of (wt%) acrylic acid 20.4-15.2%, beta-hydroxyethyl acrylate 17.3-13.1%, styrene 13.6-6.4%, n-butanol 10.7-7.4%, xylene 30.8-22.8%, ethyl alpha-cyanoacrylate 7.2-4.3%, benzoperoxide 2.0-1.0% and conventional quantity of pigment and solvent. The tests show that its resistance to shock is excellent, and other properties also are good. Its production process is simple and convenient, cost is low, so that said invented coating material can be extensively used for spray-coating various surfaces, such as aviation, machinery, ship, household appliance and various vehicles, etc..
Description
The invention belongs to chemical field, be specifically related to a kind of monocomponent hydoxy acrylic coating that is widely used in aviation, machinery, boats and ships, household electrical appliances and various surface of vehicle.
" coatings industry " 1992 the 2nd interim gensengs such as the two brave coating Wu Shao of the group company woodss in Wuhan product standards that disclose according to domestic and international colleague, the hydroxy acryl acid resin and the baking finish thereof of development, in fact the prevailing in the market product of this class polymkeric substance that all is hydroxy acryl acid resin and linking agent butylated melamine-formaldehvde resin is a kind of polyamine fat lacquer of hydroxy acryl acid; And the at present domestic blank that still belongs to of hydroxyl single component acrylic coating.
It is better than currently available products that purpose of the present invention proposes a kind of over-all properties exactly, produce more convenient, the monocomponent hydoxy acrylic coating that manufacturing cost is lower.
The present invention mainly forms (weight percent) by following raw material and content:
Vinylformic acid 20.4-15.2%
Senecioate-hydroxyl ethyl ester 17.3-13.1%
Vinylbenzene 13.6-6.4%
Propyl carbinol 10.7-7.4%
Dimethylbenzene 30.8-22.8%
Ethyl 7.2-4.3%
Benzoyl peroxide 2.0-1.0%
Pigment, solvent convention amount
The synthesis technique of above-mentioned resin is as follows:
(1) gets 15% dissolving benzoyl peroxide of dimethylbenzene total amount in the prescription;
(2) vinylformic acid, senecioate-hydroxyl ethyl ester, vinylbenzene, the ethyl of getting formula ratio is mixed and made into monomer mixed solution:
(3) with the propyl carbinol of 85% dimethylbenzene, formula ratio and whole monomer mixed solutions 5%, 20% the joining in the header tank of benzoyl peroxide solution total amount, slowly drop to again in the reactor, dripped off in 1 hour 45 minutes;
(4) limit drips the stirring of above-mentioned mixed solution limit, and slowly is warming up to 120 ℃, back flow reaction 1 hour 45 minutes, and reaction is incubated 10 minutes after finishing;
(5) be cooled to 110 ℃, begin to drip all the other monomer mixed solutions of 95% to above-mentioned reactor by the monomer jar, dripped off in 1 hour 45 minutes, back flow reaction is 1 hour 15 minutes then;
(6) add another part benzoyl peroxide, drip off in 10 minutes, insulation refluxed 2 hours;
(7) continue to be warming up to 135 ℃, remove fully until moisture, viscosity is measured in sampling at any time, wait reach requirement after, promptly 30-70S promptly begins cooling, discharging is filtered, and is canned.
With the hydroxyl single component acrylic resin of above-mentioned synthetic light golden rod yellow, high-clarity and pigment grind, disperse after, add solvent, can be made into acrylic coating of all kinds.
The key distinction of the present invention and prior art is: do not use butanols modification poly cyanamid formaldehyde resin and wilkinite, its performance obviously is better than present polyamine fat lacquer, and preparation, uses more conveniently, and cost is lower.
The present invention can be made into drying-type, self-drying type lacquer, during use, need not prime, and directly sprays, and saves time, material-saving; Carry out performance test through national coating quality supervision and inspection center and coating pigment mass supervision and inspection station, Shanghai City comparing with overseas product, the result shows that its shock-resistance is better than present similar products at home and abroad greatly, and all other performances reach or near like product.Detected result such as following table:
