The present invention has following characteristics:
(1) the present invention uses low polar materials such as vegetables oil, rosin ester in a large number, thereby prepared coating is soluble in varsol, overcome previous vacuum metallizing coating poorly soluble to varsol, disadvantage such as be easy to separate out.
(2) for improving the sticking power of coating to ground and coatings, the present invention is directed to the characteristic of general-purpose plastics and coating, add acrylic copolymer, polyhydroxylated polymer in composition, improved the sticking power of coating to ground and coatings greatly, the coating adherence is obviously improved.
(3) for adapting to harsh execution conditions, improve the planarization and the performances such as moisture-proof heat, gloss thereof of coating, the present invention has introduced has levelling property and the hot macromolecular material rosin ester of moisture-resistant in a large number, the execution of coating condition is more gentle, the use of can constructing under severe weather conditions such as high temperature, high humidity.
(4) free isocyanate of coating is zero, and the siccative that is added when using is transistion metal compound, has no side effect; Can adopt varsol as thinner in the coating application process, environmental pollution is little, compliance with environmental protection requirements.
(5) in the special-purpose vacuum metallizing coating of polyolefine, the present invention has introduced the polymer substance acrylic copolymer with reactive behavior and soft segment, can obviously improve the fragility of coating, further improves the mechanical property of paint film.
(6) coating wide accommodation of the present invention can be adapted to comprise the application of the general-purpose plastics and the reclaimed materials thereof of polyolefine, and need not to carry out surface treatment; Particularly selecting for use of modified polyolefin both can have been reduced the surface treatment of polyolefine application, can overcome again to use instability that chlorinatedpolyolefins brought, easily defective such as separate out.
(7) polyvalent alcohol is used for alcoholysis reaction, improves the adherence of coating.
(8) acid anhydrides is used to improve the tolerance and the fullness ratio of coating.
(9) isocyanic ester is used to improve hardness of paint film.
The present invention has following advantage:
(1) the present invention is fit to plastic vacuum coating, and salient features meets the whole process of vacuum plating, both can be used as priming paint, can be used as the protective cover of coating again.Compare with existing coating, the present invention's rosin ester substituted phenolic resin, product colour is lighter, is adapted to especially use as finish paint.
(2) paint stability of the present invention is good, is difficult for separating out;
(3) coating of the present invention oil is long shorter, helps improving the surface drying of coating, overcome existing coating time of drying long, energy consumption is big, under the big situation of humidity poor, the easy defective such as turn white of levelling property, can under mal-conditions such as hot and humid degree, construct.
(4) coating of the present invention can be with hydro carbons as thinner, and thinning ratio can reach 1: 10, and time limit of service reached more than 10 days, and paint film has high gloss, hardness, humidity resistance, resistance to acids and bases and the good transparency and dyeability.
(5) this coating adopts nontoxic transistion metal compound as siccative, has no side effect behind the drying varniss.
(6) this coating wide accommodation can be applicable to comprise the various plastics and the reclaimed materials thereof of polyolefine, does not need the surface treatment can direct application; Its form of construction work both can adopt traditional dip-coating method, also applicable to the spraying method of high-grade wrapping material, to improve coating quality, remedied the defective of dip-coating, improved product specification.
