Abstract

The invention discloses a formula of a plastic material with metallic luster and a preparation method thereof. The formula comprises 55 to 70 parts of SAN resin, 30 to 45 parts of ASA resin, 0.5 to 3.5 parts of aluminium powders and 1 part of antioxidant. A product prepared by the method has good metallic luster, high durability, and particularly high lightfast aging performance; the metallic luster cannot fall off or fade; even if the surface of the product is scraped and abraded, the inside of the product still has the metallic luster, and a surface treatment process of spraying metallic flashing paint or metallic surface plating layer on the surface is not needed; therefore, the plastic material is suitable to serve as an automotive workpiece and can also replace the metallic workpiece. The method is simple and easy to implement, can substantially reduce production cost, and has good use effect.

Description

technical field [0001] The invention relates to a formula and a preparation method of a plastic material, in particular to a formula and a preparation method of a plastic material with metallic luster. Background technique [0002] In automobile painting, the color (color) of the topcoat can be divided into two categories: solid colors and metallic colors. The true color can be divided into chromatic (refers to red, yellow, blue, green and other colored colors) and achromatic (refers to white, gray, black and other non-colored colors) according to its color. Metallic colors can also be subdivided into metallic flash colors and pearlescent colors, and tend to be colored. Over the past 10 years, automotive topcoats have required high decorativeness (high contrast, high brightness, and high flash coloration). The number of cars using metallic flash and pearlescent topcoats has increased year by year. More than 50% (some countries and manufacturers paint cars with metallic fla...
