Problems solved by technology

[0002] With the improvement of people's living standards, the aesthetic height of furniture has changed accordingly. Ordinary decorated furniture can no longer meet the requirements, which has given birth to the rapid development of a number of special decoration techniques. Gold painting on furniture is one of the many special techniques. , and the gold painting is generally done on the finish paint (here refers to the polyurethane topcoat PU, the same below). As we all know, on the higher hardness PU topcoat, if you paint directly without polishing, it will inevitably appear attached. The problem of paint peeling due to poor focus

Abstract

The invention discloses a nitryl golden finishing coat with ultra-high adhesive force. The nitryl golden finishing coat comprises a component A and a component B, wherein during construction, the components A and B are mixed to form a finishing coat to be constructed; the component A comprises fatty acid short-oil alkyd resins, 60 percent of rosin liquid, 40 percent of nitro-cotton liquid, a wetting dispersant, a flatting agent A, a flatting agent B, an anti-foaming agent, cyclohexanone, isobutanol, butoxyethanol, a plasticizer, n-butyl acetate, matt powder, fine silver powder, red essences, yellow essences and black essences; the component B comprises dimethylbenzene, sec-butyl acetate, isobutanol, butoxyethanol, n-butyl acetate and propylene glycol methyl ether acetate. Based on detection and trial certification, the nitryl golden finishing coat is high in adhesion force of coatings, high in covering power, and suitable for coating gold on a grinding-free PU finishing coat.

Description

technical field [0001] The invention relates to a nitro-based finish paint with super high adhesion, which belongs to the field of wood coatings. Background technique [0002] With the improvement of people's living standards, the aesthetic height of furniture has changed accordingly. Ordinary decorated furniture can no longer meet the requirements, which has given birth to the rapid development of a number of special decoration techniques. Gold painting on furniture is one of the many special techniques. , and the gold painting is generally done on the finish paint (here refers to the polyurethane topcoat PU, the same below). As we all know, on the higher hardness PU topcoat, if you paint directly without polishing, it will inevitably appear attached. The problem of paint peeling due to poor focus. The present invention will develop a nitro-based color finish paint with super strong adhesion through formula innovation, so as to achieve the purpose of strengthening the adhe...
