Abstract

The invention discloses an anti-static polybutylene terephthalate (PBT) material with excellent comprehensive performance. The anti-static PBT material with excellent comprehensive performance comprises the following components in part by weight: 40 to 70 parts of PBT resin, 20 to 40 parts of glass fiber, 1 to 7 parts of carbon nanotube, 0.1 to 0.5 part of antioxidant, 0.1 to 0.5 part of lubricating agent and 1 to 5 parts of toughening agent. The carbon nanotube serves as a conductive filler of the PBT, so the material has an excellent anti-static property and the mechanical property of the material is improved; the glass fiber is used for reinforcing the PBT material, so the notch sensitivity of the PBT is overcome; and the mechanical property of the material is improved, high anti-static property is achieved, and the diversified requirement of the market is met. The processing technology is simple; the product quality is stable; the comprehensive performance is excellent; and a good market prospect is achieved.

Description

technical field

[0001] The invention relates to an engineering plastic PBT, in particular to an antistatic PBT material with excellent comprehensive performance and a preparation method thereof. Background technique

[0002] PBT resin is a new type of engineering plastic with excellent comprehensive performance. It has excellent mechanical, electrical, chemical corrosion resistance, easy molding and low hygroscopicity, but it also has low heat distortion temperature, high notch impact sensitivity, high temperature, etc. Poor dimensional stability, easy to burn and other defects limit its application range. For this reason, research and development have been carried out on the modification of PBT resin at home and abroad, and good results have been achieved. Modified PBT is widely used in the automotive industry, mechanical equipment casings, electronic and electrical and instrumentation parts. However, PBT is an insulator with poor antistatic performance, and it is easy to...
