▎ 摘 要
NOVELTY - The preparation method of natural rubber composite material involves adding graphene, layered silicate and white carbon black in a mass ratio of 1-5:1-10:10-30 to a reactor and then mixing, adding water and dispersant to the mixture and then stirring, adding 20-70 pts. wt. natural latex solution to the mixture and then washing, adding 3-10 pts. wt. zinc oxide, 1-5 pts. wt. stearic acid, 2-6 pts. wt. antioxidant, 2-7 pts. wt. silane coupling agent, 0-30 pts. wt. reinforcing agent, 6-10 pts. wt. aromatic oil, 1.5-2.5 pts. wt. sulfur and 1-2 pts. wt. accelerator to the mixture and mixing for 3-5 minutes. USE - The method is useful for preparation of natural rubber composite material, which is useful for conveyor belt covering adhesive. ADVANTAGE - The method enables preparation of natural rubber composite material with excellent mechanical properties, wear resistance and prolonged service life in environmentally-friendly manner.
