Abstract
The invention discloses a polyester finish coat for coil steel, which comprises the following components in percentage by weight: 30-40% of methylated melamine resin, 10-20% of epoxy modified polyester resin, 10-20% of blocked isocyanate, 10-15% of titanium white, 2-10% of phthalocyanine blue, 0.3-0.8% of hindered amine photostabilizer, 0.1-0.3% of 2-hydroxy-4-methoxydiphenyl ketone, 0.8-1.5% of triethylenediamine, 0.2-0.5% of diisopropyl di(acetylacetone)titanate and 10-15% of diluter. The polyester finish coat for coil steel is easy to apply, and has the characteristics of high coating surface hardness, high pollution resistance, high corrosion resistance, high temperature resistance and the like.
Description
Technical field
The present invention relates to a kind of paint, specifically, relate to a kind of coil polyester finish coat.
Background technology
Colored coil is widely used in the fields such as construction industry, automobile, household electrical appliances, but coloured coating difference of hardness, the resistance to soiling on existing colored coil surface low, be easy to be corroded, these shortcomings have hindered the development of colored coil.Therefore, need a kind of new technical scheme to solve above-mentioned technical problem.
Summary of the invention
The object of the present invention is to provide a kind of coil polyester finish coat, it has that coatingsurface hardness is high, anti-pollution characteristic good and the characteristics such as corrosion-resistant.
The object of the invention realizes by following technical proposals:
A kind of coil polyester finish coat, by weight percentage, it comprises following composition: methyl-etherified melamine resin 30%～40%, epoxy modified polyester resin 10%～20%, masked isocyanate 10%～20%, titanium dioxide 10%～15%, phthalocyanine blue 2%～10%, steric hindrance amine photostabilizer 0.3%～0.8%, ESCALOL 567 0.1%～0.3%, triethylenediamine 0.8%～1.5%, two (acetylacetone based) metatitanic acid diisopropyl ester 0.2%～0.5%, thinner 10%～15%.
It is main film forming substance that the present invention has adopted the methyl-etherified melamine resin, and it mainly is distributed in the surface of paint coating afterwards in baking, improves hardness and the resistance to soiling of coatingsurface, has imported steric hindrance amine photostabilizer to improve the erosion resistance of paint simultaneously.
Beneficial effect of the present invention: be easy to coating, high, the resistance to soiling of coatingsurface hardness and good corrosion resistance, also there is the characteristics such as high temperature resistant simultaneously.
