Abstract

The invention discloses an APET anti-static material and a manufacturing method thereof. The APET anti-static material comprises, by weight, 60-70 parts of polyethylene glycol terephthalate, 30-35 parts of polyvinylidene chloride, 15-18 parts of polyvinyl alcohol, 12-15 parts of polyacetylene, 3-6 parts of poly-p-phenylene terephthamide, 3-5 parts of styrene oxide, 1-2 parts of bis(bis-chlorin dimethylsilyl)benzene, 0.5-1 part of dimethylol acrylic acid, 0.2-1 part of magnesium chloride, 0.2-1 part of aluminum chloride and 0.02-0.5 part of dicumyl peroxide. The invention further provides the manufacturing method of the APET anti-static material.

Description

technical field [0001] The invention belongs to the field of antistatic materials, in particular to an APET antistatic material and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET) is one of the most important varieties of thermoplastic polyester, commonly known as polyester resin. PET is obtained by transesterifying dimethyl terephthalate and ethylene glycol or esterifying terephthalic acid and ethylene glycol to synthesize bishydroxyethyl terephthalate, followed by polycondensation. Polyethylene terephthalate can be divided into APET, RPET and PETG. [0003] PET is a milky white or light yellow, highly crystalline polymer with a smooth and shiny surface. It has excellent physical and mechanical properties in a wide temperature range. The long-term use temperature can reach 120 ° C. It has excellent electrical insulation. Even at high temperature and high frequency, its electrical properties are still good, but its corona resist...
