Abstract

The invention belongs to the technical field of high polymer materials, and relates to an impact-resistant conductive polyphenylene sulfide material and a preparation method thereof. The impact resistant conductive polyphenylene sulfide material is prepared from the following components in parts by weight: 60-75 parts of PPS, 0.5-1 part of a lubricant, 0.5-0.8 part of epoxy resin, 8-15 parts of a toughening agent, 17-25 parts of carbon black and 0.5-2 parts of a coupling agent. The impact-resistant conductive polyphenylene sulfide material is prepared by using a high-speed pre-mixing dispersion one-step extrusion process. The impact-resistant conductive polyphenylene sulfide material provided by the invention has the characteristics of being good in mechanical property, good in flame retardancy, good in stability, easy to process, good in impact resistance and the like, and is applicable to packages of precise and advanced products of the electronic industry, the war industry and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to an impact-resistant conductive polyphenylene sulfide material and a preparation method thereof. Background technique [0002] Some high-end products in electronic appliances and military products need to be carried and protected by containers during use, production, and transportation. In order to prevent static electricity generated by friction between electronic appliances and containers, resulting in damage to electronic appliances, these containers are all made of conductive Made of plastic. [0003] The existing conductive plastic is mainly composed of plastic, conductive carbon black, carbon nanotube or carbon fiber and various additives. Carbon fiber and carbon nanotubes have the characteristics of small dosage and little impact on material properties, but compared with carbon black, their cost is much higher. At present, the market is mainly based on carbon blac...
