Abstract

The invention relates to the technical field of high polymer materials, in particular to a glass fiber reinforced PPS-CNT (polyphenylene sulfide-carbon nano tube) conductive composite and a preparation method thereof. The PPS-CNT conductive composite is prepared from raw materials in parts by weight as follows: 30-70 parts of PPS raw powder, 3-15 parts of CNTs, 1-5 parts of a toughening compatibilizer, 0.1-0.2 parts of a heat stabilizer, 0.1-2.0 parts of a lubricant and 20-60 parts of glass fibers. The glass fiber reinforced PPS-CNT conductive composite with high cost performance and high performance is provided in order to solve the problems that an existing graphite conductive PPS material does not have sufficient mechanical property and is high in addition amount and difficult to process and a carbon fiber conductive PPS material is high in adding proportion, poor in dispersion and high in cost.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a glass fiber reinforced PPS-CNT conductive composite material and a preparation method thereof. Background technique [0002] Polyphenylene sulfide (PPS) is a crystalline polymer with phenylthio groups in its main chain. The melting point of PPS raw powder is usually between 275-290°C. The defect of unmodified PPS is low strength and easy stress cracking of the product. PPS modified with glass fiber has high rigidity, and it is easy to fall on the ground. Crisp steel sound. [0003] The Chinese invention patent with the application number 201711186277.8 discloses a conductive and thermally conductive PPS, which includes: PPS resin 40-60, polysulfone resin 10-20, silane coupling agent 0.2-0.5, carbon fiber 20-30, Graphite 10-20, nano-silicon carbide 0.5-1, EBS dispersion flow agent 0.4-1. At present, in the modification of PPS engineering plastics, the conductive mod...
