Abstract

The invention provides a high-temperature-resistant antistatic PBT (polybutylene terephthalate) material and a preparation method thereof. This material is made from the following components according to parts by weight: 60-70 parts of polyethylene terephthalate, 15-20 parts of polymer polyol, 5-10 parts of nanosilver-modified dihydroxy polydiphenylsiloxane, 3-10 parts of a flexibilizer, 10-15 parts of an antistatic agent 0.5-3 parts of an antioxidant, 4-8 parts of a dispersant and 1-5 parts of a light shielding agent. By adding the polymer polyol and the nanosilver-modified dihydroxy polydiphenylsiloxane and utilizing their synergy, the prepared PBT material has good antistatic performance and can still retain good mechanical properties at high temperature.

Description

technical field [0001] The invention relates to an antistatic material, in particular to a high temperature resistant antistatic PET material and a preparation method thereof. Background technique [0002] Polybutylene terephthalate, English name polybutylene terephthalate (referred to as PBT), belongs to the polyester series, which is composed of 1.4-pbt butanediol (1.4-Butylene glycol) and terephthalic acid (PTA) or terephthalic acid Formic ester (DMT) polycondensation, milky white translucent to opaque, crystalline thermoplastic polyester resin produced through mixing procedures, has excellent mechanical properties and processing properties. In order to make PBT materials more widely used in the automotive, electronics, and electrical industries, it needs to have better antistatic properties, and it is best to optimize other properties and prolong its service life at the same time. [0003] CN 106530656A discloses an antistatic PBT material and its preparation method. Th...
