Abstract

The invention provides a formula of a non-painted automobile bumper with metal luster and a production process thereof. The automobile bumper is prepared from the following components in part by weight: 60 to 90 parts of PP, 8 to 12 parts of POE, 0.5 to 1.5 parts of aluminum powder and 8 to 12 parts of talcpowder. The automobile bumper produced by adopting the technique of blending the aluminum powder, PP and POE, the paint-spraying process is saved, the metal luster is obtained, the environment is protected, the paint-spraying process step in the production process is eliminated, the product produced by the formula and the method has the effect of the metal flashing paint sprayed on the surface, and the metal luster is high in durability and is not lost due to environmental factors as well as surface abrasion; and in addition, because the surface of the automobile bumper is not painted, the automobile bumper is recovered more conveniently.

Description

technical field [0001] The invention relates to a formula and a production process of a plastic material, in particular to a formula and a production process of a paint-free automobile bumper with metallic luster. Background technique [0002] In automotive painting, the color (color) of the topcoat can be divided into two categories: natural colors (solidcolors) and metallic colors (metalliccolors). According to its color, the natural color can be divided into chromatic (referring to red, yellow, blue, green and other colors with color) and achromatic (referring to white, gray, black and other non-colored colors). Metallic colors can also be subdivided into metallic flash colors and pearlescent colors, and have a tendency to be colored. Over the past 10 years, automotive topcoats require high decoration (high vividness, high brightness, high flash colorization), and the number of vehicles using metallic flash and pearlescent topcoats has increased year by year, and it has ...
