Abstract

The invention discloses a weather-resistant and glossy black finishing paint capable of being adhered to metal materials. The weather-resistant and glossy black finishing paint is formed by mixing a component A, a component B and a component C according to a weight ratio of 1:(0.8 to 1):(0.3 to 0.5), wherein the component A is prepared from black slurry, organosilicone resin, cellulose acetate liquid, butyl acetate and multiple types of additives; the component B is prepared from n-butyl acetate and other curing agents; the component C is prepared from xylene, 40% n-butyl acetate and propyleneglycol methyl ether acetate. Proofed by detection and testing, the weather-resistant and glossy black finishing paint has the advantages that after spraying, the flatting property of a paint film isgood, the adhesion force is good, the weather-resistant property is good, and the weather-resistant and glossy black finishing paint is suitable for spraying workpieces with different metal materials;the problems of delamination, gloss losing, discoloring and other poor weather-resistant property in the paint film covered by the existing black finishing paint are solved, and the service life of the paint film is prolonged.

Description

technical field [0001] The invention relates to the wood coating manufacturing industry, in particular to a weather-resistant glossy black finish that can be attached to metal materials. Background technique [0002] In addition to wooden furniture, modern furniture, fabric furniture and metal furniture are also becoming popular. With the promotion of the application of metal materials in furniture, when faced with decorative furniture made of different metal materials, the choice of coating is a difficult problem. After the ordinary glossy black topcoat is sprayed, due to the limitation of the paint film performance, when coating furniture made of different metal materials, especially in some climate conditions that need to face wind and sun, heat expansion and contraction, and surfaces When fuming the oily fumes in the kitchen, the paint film formed after painting is prone to delamination, loss of gloss, and discoloration, which greatly affects the service life and appear...
