Abstract

The invention relates to the technical field of polycarbonate, and especially relates to an aging-resistant polycarbonate composition. The aging-resistant polycarbonate composition comprises the following components in parts by mass: 3-12 parts of malonate, 3.5-6.8 parts of nano titanium dioxide, 15-25 parts of pentaerythritol, 10-20 parts of mica, 5-12 parts of polysiloxanes-polycarbonate, 2.6-4.2 parts of glass fiber, 30-45 parts of polycarbonate, 12-18 parts of an ultraviolet resistance agent, and 1.5-3.9 parts of stearamide. The polycarbonate composition is helpful for improving the injection liquidity, and reducing the electrostatic force of the following produced products, and at the same time, improving the efficacy of the integral production process and the quality of the produced products. The polycarbonate composition resists aging.

Description

technical field [0001] The invention relates to the technical field of polycarbonate, in particular to an aging-resistant polycarbonate composition. Background technique [0002] Polycarbonate (referred to as PC) 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 produced industrially. Due to the special structure of polycarbonate, it has become the fastest-growing general-purpose engineering plastic among the five major engineering plastics. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-aging polycarbonate composition. [0004] In order to solve the above-men...
