NOVELTY - Damping ring based on graphene/polymer composite material comprises graphene/polymer composite material, which comprises polymer as substrate and graphene as filler. The polymer comprises chloroprene rubber, ethylene oxide/propylene oxide (EO/PO) block polyether, active agent zinc oxide, plasticizer phthalic acid dicyclohexyl ester, anti-aging agent 2,2,4-trimethyl-1,2-dihydroquinoline, reinforcing agent phenolic resin, plasticizer dicyclohexyl phthalate, accelerator DETU, accelerator diphenyl guanidine (DPG) and sulfur. USE - Damping ring based on graphene/polymer composite material. ADVANTAGE - The damping ring based on graphene/polymer composite material has simple preparation and solves the problem of poor wear resistance of damping ring made of neoprene as main material. DETAILED DESCRIPTION - Damping ring based on graphene/polymer composite material comprises graphene/polymer composite material, which comprises polymer as substrate and graphene as filler. The polymer comprises 100 pts. wt. chloroprene rubber, 5-12 pts. wt. EO/PO block polyether, 6-15 pts. wt. active agent zinc oxide, 4-15 pts. wt. plasticizer phthalic acid dicyclohexyl ester, 4-15 pts. wt. anti-aging agent 2,2,4-trimethyl-1,2-dihydroquinoline, 9-16 pts. wt. reinforcing agent phenolic resin, 12-20 pts. wt. plasticizer dicyclohexyl phthalate, 3-10 pts. wt. accelerator DETU, 3-10 pts. wt. accelerator DPG and 0.6-1.2 pts. wt. sulfur. Graphene is at 0.06-18 pts. wt.
