Abstract

The present invention discloses a PET / PTT alloy material of excellent anti-aging and conductive performances, which comprises the following components in mass percentage: 30-58% of PET, 20-30% of PTT, 2-4% of E-MA-GMA, 1-3% of nanosilicon dioxide, 8-12% of glass fibers, 5-10% of graphitized carbon black, 5-8% of MBS, 0.5-2% of light stabilizer, 0.1-0.5% of anti-oxidant and 0.1-1% of lubricant. The graphitized carbon black is super conductive black. The light stabilizer is a compound of a hindered amine light stabilizer HS-944 and a hindered amine light stabilizer HS-622 in the mass ratio of 1:1. According to the invention, the PET / PTT alloy material is excellent in mechanical strength, rigidness, heat resistance, anti-aging resistance, conductivity, chemical resistance and processability, and low in cost.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a PET / PTT alloy material with good aging resistance and electrical conductivity. Background technique [0002] PET / PTT (polyethylene terephthalate / polytrimethylene terephthalate) alloy has excellent properties such as molding processing, impact resistance, high temperature heat aging resistance, and chemical resistance, so it is used in automobiles, electronic appliances, etc. , home appliances, fiber and other fields will have broad application prospects. However, unmodified PET / PTT has the problems of unstable mechanical strength and poor aging resistance, which will greatly limit its application effect and application field. In order to improve the performance, it is often necessary to add a third component to the PET / PTT alloy for modification, in order to improve the performance and expand the application field. Contents of the invention [0003] The purpose of...
