Description

technical field

[0001] The invention relates to a conductive thermoplastic dynamic vulcanized silicone rubber and a preparation method thereof. Background technique

[0002] Dynamic vulcanization is an emerging rubber vulcanization technology. It is a process of melting and blending unvulcanized rubber with thermoplastic materials under high shear, and adding a vulcanizing agent to vulcanize it. In this process, the thermosetting rubber phase (dispersed phase) is uniformly dispersed in the thermoplastic material (continuous phase) in a certain particle size range, and at the same time the rubber phase particles are cross-linked, and finally thermoplastic dynamic vulcanizate (TPV) is obtained. The most important feature of dynamic vulcanization is to carry the thermosetting rubber phase in thermoplastic materials, so as to combine the properties of thermosetting rubber and thermoplastic plastics, and at the same time facilitate the processing and recycling of materials.
