Problems solved by technology

Under the harsh conditions required by vacuum coating, the paint is prone to produce illusion, matte and other phenomena, the paint film adhesion is extremely poor, the paint is extremely unstable after dilution, and it is easy to produce precipitation and other phenomena, which will affect the construction effect; some paints Even heavy metal salts such as lead are used as drier, which is highly toxic
The "vacuum coating coating" announced by Chinese patent CN1168793C uses phenolic resin to modify urethane oil, although the performance of the coating can be partially improved, but due to improper formulation, the product is extremely unstable and cannot fundamentally solve the brittleness of this type of coating , easy to precipitate and other common problems

Abstract

A paint for the vacuum deposition on plastics is proportionally prepared from plant oil, polyol, acid anhydride, rosin, acrylic copolymer, polyhydroxy polymer, modified polyolefin, isocyanate and solvent mixture through alcoholysis, esterifying, addition reaction and aminoesterifying.

Description

technical field [0001] The invention relates to a paint composition, in particular to a primer and a surface paint used in vacuum coating technology. Background technique [0002] Most of the early vacuum coating coatings used urethane oil and alkyd modified urethane oil. They were made of linseed oil, benzoic anhydride, pentaerythritol, modified phenolic resin, and toluene diisocyanate. Through alcoholysis, esterification, Condensation, and add drier to prepare. Under the harsh conditions required by vacuum coating, the paint is prone to produce illusion, matte and other phenomena, the paint film adhesion is extremely poor, the paint is extremely unstable after dilution, and it is easy to produce precipitation and other phenomena, which will affect the construction effect; some paints Even heavy metal salts such as lead are used as drier, which is more toxic. The "vacuum coating coating" announced by Chinese patent CN1168793C uses phenolic resin to modify urethane oil, al...
