Abstract

The invention discloses polyvinyl chloride and polyethylene composite modified plastic. The polyvinyl chloride and polyethylene composite modified plastic comprises polyvinyl chloride, polyethylene and additives, wherein the additives comprise a plasticizer, a filler, a thermal stabilizer, a weather resistant agent and an antioxidant, the plasticizer is diisopropyl phthalate, the filler is emery, the thermal stabilizer is dibutyltin dichloride, the weather resistant agent is phenyl salicylate, and the antioxidant is butyl hydroxy anisd. Therefore, the made polyvinyl chloride and polyethylene composite modified plastic has the effects of high rigidity, good mechanical strength, good weather resistance, good thermal stability, aging resistance and the like.

Description

technical field [0001] The invention relates to a plastic formula, in particular to a composite modified plastic made of polyvinyl chloride and polyethylene. Background technique [0002] Polyvinyl chloride is a plastic obtained by the polymerization of vinyl chloride. Its strength can be adjusted by additives. Its hard and soft products are widely used, but generally the rigidity of polyvinyl chloride is average and its mechanical strength is poor. Polyethylene has excellent low temperature resistance (the lowest operating temperature can reach -70~-100°C), good chemical stability, can resist most acid and alkali erosion (not resistant to oxidizing acids), and is insoluble in general solvents at room temperature , low water absorption, excellent electrical insulation properties, but polyethylene is very sensitive to environmental stress (chemical and mechanical effects), not heat-resistant, and easy to age. Contents of the invention [0003] The object of the present inv...
