▎ 摘  要

NOVELTY - Environmentally-friendly oil seal material comprises 30-45 pts. wt. urethane rubber, 25-50 pts. wt. acrylate rubber, 5-20 pts. wt. white carbon black, 3-10 pts. wt. carbon nanotubes, 1-3 pts. wt. stearic acid, 1-5 pts. wt. graphene, 3-8 pts. wt. mold release agent, 10-20 pts. wt. antioxidant, 0.5-1 pts. wt. 2,2-dithiodibenzothiazole, 1-2 pts. wt. tetraethylthiuram disulfide and 1-3 pts. wt. dispersant. USE - Used as environmentally-friendly oil seal material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing environmentally-friendly oil seal material comprising (i) adding urethane rubber and acrylate rubber into kneader, and kneading at 150 degrees C for 30 minutes, (ii) adding white carbon black, carbon nanotubes, graphene, mold release agent, antioxidant and dispersant, and mixing again, (iii) adding stearic acid, 2,2-dithiodibenzothiazole, tetraethylthiuram disulfide, stirring again uniformly; kneading at 180 degrees C for 30 minutes to obtain final product.
