Abstract

The invention provides a formula of a non-painted automobile spoiler with metal luster and a production process thereof. The automobile spoiler is prepared from the following components in part by weight: 90 to 100 parts of PP, 5 to 10 parts of talcpowder and 0.5 to 3.5 parts of aluminum powder; or 90 to 100 parts of ABS and 0.5 to 1.5 parts of aluminum powder. The automobile spoiler produced by blending the aluminum powder and the PP or ABS; by using the PP or ABS as a raw material to produce the automobile spoiler, the surface of the automobile spoiler can obtain the metal luster without spraying treatment, and the metal luster is not lost or fades, the inner part of the product still obtains the metal luster even if the surface of the product is scratched or damaged, the surface treatment process of spraying the metal flashing paint on the surface of the product is unnecessary, and the metal luster is high in durability, particularly excellent in light ageing resistance; and in addition, the paint-spraying process step in a process of producing the automobile spoiler adopting the formula is saved, so that the production flow is simplified, and the production cost is greatly lowered.

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 spoiler 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% (in some countries and manufacturers, cars painte...
