▎ 摘  要

NOVELTY - Vibration damping rubber comprises 100 pts. wt. raw rubber matrix, 3-10 pts. wt. graphene pre-dispersed masterbatch. The graphene pre-dispersed masterbatch is graphene pre-dispersed masterbatch with rubber as a carrier and a graphene pre-dispersed masterbatch with stearic acid as a carrier. USE - The vibration damping rubber is useful in field of rubber shock absorbers for vibration isolation devices for main and auxiliary aircraft of ships that suppress vibration conduction, and rubber shock absorbers for engines e.g. motor vehicles. ADVANTAGE - The vibration damping rubber: has low damping, low creep deformation and high strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing vibration damping rubber comprising preparing a mixed rubber having raw rubber matrix and graphene pre-dispersed masterbatch, and the step of vulcanizing and molding mixed rubber at 135-145degrees Celsius, and in the step of vulcanizing molding, the production vulcanization time of rubber products is the value obtained by adding 0.3 times (minutes) of the positive vulcanization time T90 (minutes) of the rubber material process plus the value of the thickness of the rubber product (absolute value in mm).
