Abstract

The invention discloses an anti-aging PC-PE (poly carbonate-poly ethylene) plastic alloy which consists of the following components in parts by weight: 100 parts of PC, 5-15 parts of PE, 1-3 parts of compatilizer and 0.5-1.5 parts of anti-aging agent. By adopting the anti-aging PC-PE plastic alloy disclosed by the invention, various mechanical parts, electronics parts, sheets, pipes, containers, helmets and the like can be manufactured by the forming processes such as injection, extrusion and the like; and the anti-aging PC-PE plastic alloy disclosed by the invention has excellent thermal aging performance and is applicable to an extreme high-temperature environment.

Description

technical field [0001] The invention relates to a plastic alloy, in particular to an anti-aging PC-PE plastic alloy. Background technique [0002] Polyethylene English name: polyethylene, referred to as PE, is a thermoplastic resin obtained by polymerization of ethylene. In industry, it also includes copolymers of ethylene and a small amount of α-olefins. Polyethylene is odorless, non-toxic, feels like wax, has excellent low temperature resistance (the lowest operating temperature can reach -70 ~ -100 ° C), good chemical stability, and can withstand most acid and alkali erosion (not resistant to oxidation properties) acid), insoluble in general solvents at room temperature, low water absorption, excellent electrical insulation properties. [0003] 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 o...
