Abstract

The invention discloses a composite plastic having stability, which comprises the following components in parts by weight: 30-40 parts of PVC; 10-20 parts of resin powder; 0.5-1.5 parts of an anti-UVagent; 1-2 parts of carbon black; 0.6-1.3 parts of a light stabilizer; and 0.5-1 part of a photodegradation agent. The composite plastic has the beneficial effects that the ratio is scientific and reasonable, PVC and the resin powder are the main raw materials, and the added additives do not contain halogen or lead, and are more environmentally friendly and do not cause pollution, at the same time, the degradation effect is fast, and the added light stabilizer has the good stabilizing effect.

Description

technical field [0001] The invention relates to a plastic, in particular to a stable composite plastic. Background technique [0002] PVC (polyvinyl chloride) is a thermoplastic resin polymerized by vinyl chloride under the action of an initiator. It is a homopolymer of vinyl chloride. Vinyl chloride homopolymer and vinyl chloride copolymer are collectively referred to as vinyl chloride resin. PVC has good mechanical properties, the tensile strength is about 60mpa, the impact strength is 5-10kj / m2, and it has excellent dielectric properties, but it has poor stability to light and heat. Decomposition produces hydrogen chloride, and further autocatalytic decomposition causes discoloration and rapid decline in physical properties. In practical applications, stabilizers must be added to improve the stability to heat and light. In terms of specific applications, according to the main properties of PVC products, it can be divided into rigid PVC and soft PVC. Among them, rigid PV...
