Abstract

The invention relates to a coating for automotive upholstery, in particular to a high-wear-resistance coating for automotive upholstery and a preparation method thereof.The high-wear-resistance coating for automotive upholstery comprises a component A and a component B. The component A comprises, by weight, 2-20 parts of effect pigment; 10 to 60 parts of main resin; 3 to 30 parts of organic fluorine-silicon modified resin; 2-20 parts of a shaking auxiliary agent; 0.5 to 10 parts of an auxiliary agent; 10 to 40 parts of a solvent; a component B: 2 to 20 parts of diisocyanate; 0.2 to 2 parts of an auxiliary agent; and 2-20 parts of a solvent. Compared with the prior art, the modified aldehyde ketone resin is selected as a matrix, the adhesion performance between a paint film and a material can be effectively improved, and the prepared paint is good in water resistance and chemical resistance. The modified aldehyde ketone matrix resin has high molecular weight, can effectively improve the Flip-Flop value of the silver powder, enables the arrangement effect of the silver powder to be excellent, can improve the shielding power of the metallic pigment, and can effectively improve the water resistance, alcohol resistance and high weather resistance of a coating.

Description

technical field [0001] The invention relates to a paint for automobile interior parts, in particular to a high wear-resistant paint for automobile interior parts and a preparation method thereof. Background technique [0002] At present, the pursuit of various car manufacturers in the interior of the car is to further improve the comfort, safety and decoration of the interior space of the car, and to develop in a more advanced direction. However, the plastic itself is not ideal for environmental aging such as ultraviolet light resistance, and various defects are often generated on the surface during the processing and molding process. Therefore, it is necessary to paint the surface of the plastic mold, give the plastic a special color or a certain luster, and cover the defects on the plastic surface, so that it has a more attractive appearance. At the same time, it can also play a protective role, so that the plastic is not harmed by adverse factors such as high temperature...
