▎ 摘　　要

NOVELTY - Graphene flame retardant constraining damping sheet comprises constraining layer, damping layer, and substrate from inside to outside. The damping layer comprises 100 pts. wt. bromo/chlorobutyl rubber, 10-20 pts. wt. natural rubber, 1-5 pts. wt. compatibilizer, 5-10 pts. wt. graphene nanosheets, 5-10 pts. wt. softener, 5-10 pts. wt. reinforcing agent, 1-5 pts. wt. vulcanizing agent, and 5-10 pts. wt. flame retardant. USE - Graphene flame retardant constraining damping sheet used for vehicles (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the damping sheet comprising mixing raw materials uniformly, extruding into sheet by single screw extruder to obtain damping layer, and bonding damping layer to constraining layer and substrate.
