NOVELTY - Flexible high temperature resistant sealing material comprises 40-50 pts. wt. amorphous fluororesin, 5-12 pts. wt. poly(styrenebethylenecobutylenebstyrene) (SEBS), 10-18 pts. wt. ethylenealphaolefin copolymer (POE), 3-8 pts. wt. spiral carbon nanotube, 3-8 pts. wt. graphene, 1-5 pts. wt. zinc hard fatty acid, 1-3 pts. wt. zinc oxide, 0.1-1 pts. wt. talcum powder and 0.01-0.1 pts. wt. vulcanizing agent. USE - Flexible high temperature resistant sealing material used for lithium battery sintering furnace. ADVANTAGE - Amorphous fluororesin is in a gel state in a molten state, and the ethylenealphaolefin copolymer (POE) has narrow molecular weight distribution and better fluidity, graphene and spiral carbon nano tube is uniformly dispersed by matching the amorphous fluororesin and the POE, so that a two-dimensional-three-dimensional heat dissipation network structure is formed, and the high temperature resistance and the flexibility of the material is further improved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for method for preparing a flexible high temperature resistant sealing material involves adding the amorphous fluororesin, poly(styrenebethylenecobutylenebstyrene) (SEBS) and ethylenealphaolefin copolymer (POE) to the automatic mixer, mixing evenly to obtain the resin material. Granulating the resin material by wet method to obtain a free-flowing material. During the granulation process, adding spiral carbon nanotubes, zinc hard fatty acid, graphene, zinc oxide, talcum powder, and vulcanizing agent to the resin material in sequence, in the molten material. Adding the free-flowing material into the forming mold and perform pressure forming to obtain a blank. Sending the blank to the vulcanizing machine for vulcanization. After vulcanization, adding the mold core in a hot air drying oven, drying and ventilating.
