Description
Technical field
The present invention relates to a kind of coating, particularly a kind of epoxy resin decoration paint.
Background technology
Epoxy resin-based paint generally has extremely strong sticking power, and particularly the sticking power to metal is stronger, the water tolerance of its non-corrosibility, paint film, chemical resistant properties and good thermal stability, paint film tough and hard wear resistant.But the film appearance poor of this class lacquer, fullness ratio is not enough, and weathering resistance is poor, easily the efflorescence loss of gloss.So this class lacquer is mainly used in preservative property priming paint at present, and should not make high-quality outdoor finish paint and flawless finish lacquer.As the disclosed a kind of epoxy lacquer with silver powder of Chinese patent CN1051746, mainly form, as the interior rustproof lacquer of antiseptic project by Resins, epoxy, silver powder, talcum powder, carbolineum, mica powder and zinc oxide.Chinese patent CN1335343 discloses a kind of antirust priming paint, and mainly by Resins, epoxy, aminoresin, PVB resin, aluminium triphosphate, glass flake, iron mica, mica powder are formed.How keeping the advantage of existing epoxy resin-based paint, overcome its deficiency, make it enlarge its range of application as environment-friendly type outdoor finish paint and flawless finish lacquer, also is the problem that present this area need solve.
Summary of the invention
Problem to be solved by this invention provides a kind of have base material anticorrosion and ornamental environment-friendly type outdoor finish paint and the flawless finish epoxy resin decoration paint that coats with lacquer.
The technical scheme that addresses the above problem is that the epoxy resin decoration paint that is provided comprises first, second component:
The first component mainly is made up of matrix resin, thinner, initiator and auxiliary agent, and the weight ratio of each storeroom is: matrix resin 25～70%, thinner 20～60%, initiator 5～12%, auxiliary agent 0.5～4%; Wherein matrix resin mainly is made up of Resins, epoxy, acrylic resin, Acrylic Acid Monomer, and the weight ratio of each storeroom of matrix resin is: Resins, epoxy 30～70%, acrylic resin 20～60%, Acrylic Acid Monomer 5～15%;
Certainly, also include pigment, stopping composition etc. in the first component, these all are the known essential additives of lacquer series products, and the present invention repeats no more.
The second component is a solidifying agent, is that 30～65% isocyanate addition product, 2～5% N methyldiethanolamine and 30～65% polymeric polyisocyanate are formed by weight ratio mainly;
Weight proportion between first, second component is a first: second=1: 0.5～0.8.
During use, with first, second component thorough mixing, slaking was used in 0.5～1 hour again.
The preferable range of above-mentioned material is as follows:
The weight ratio that matrix resin accounts for the first component is 42～60%, and the weight ratio that thinner accounts for the first component is 33～50%; The weight ratio that Resins, epoxy accounts for matrix resin is 40～50%, and the weight ratio that acrylic resin accounts for matrix resin is 35～50%.
The weight ratio that isocyanate addition product accounts for the second component can be 40～55%; The weight ratio that polymeric polyisocyanate accounts for the second component can be 40～55%.
Resins, epoxy in the above-mentioned first component matrix resin preferentially adopts bisphenol A epoxide resin.
Thinner in the above-mentioned first component matrix resin can be used the mixing solutions of alcohols and ester class.
Raw material of the present invention is easy to get, and is cheap, and containing benezene solvent not, so environmentally safe; Experiment shows, uses the erosional competency of formed paint film acid-and base-resisting of the present invention and salt strong, smooth surface, light, level and smooth, and it is ornamental fabulous.
