Abstract

The invention relates to a plastic used for automobile lamps. The plastic is composed of, by weight, 0.1 to 0.5% of a flexibilizer, 0.1 to 0.5% of a colourment, 0.1 to 0.8% of an anti-oxidant, 0.2 to 0.9% of a coupling agent, and the balance PC resin, wherein the anti-oxidant is a metallic oxide nano-material. The plastic possesses excellent oxidation resistance, so that cost increasing caused by material aging is avoided, and the plastic can be widely used for manufacturing of automobile lamps.

Description

technical field [0001] The invention belongs to the technical field of chemical materials, and in particular relates to a plastic used for automobile lamps. Background technique [0002] PC refers to polycarbonate, which is a high molecular polymer containing carbonate groups in the molecular chain. According to the structure of the ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. Among them, the low mechanical properties of aliphatic and aliphatic-aromatic polycarbonates limit their application in engineering plastics. At present, only aromatic polycarbonate has been industrialized. Due to the special structure of polycarbonate, it has become the fastest-growing general-purpose engineering plastic among the five major engineering plastics. However, polycarbonate has poor resistance to organic chemicals and scratches, and it will turn yellow and discolored after ultraviolet radiation, which seriously affects its aesthetics, espec...
