▎ 摘　　要

NOVELTY - Non-metallic anti-heat decay composite brake pad comprises friction material, bottom material and steel back. The friction material comprises 8-12 pts. wt. porous titanium carbide, 15-20 pts. wt. graphene modified styrene-acrylic emulsion, 8-12 pts. wt. porous silicon nitride ceramic powder, 9-11 pts. wt. flake graphite, 2-5 pts. wt. polytetrafluoroethylene, 9-12 pts. wt. sepiolite fiber, 4-5 pts. wt. magnesium oxide, 6-10 pts. wt. alumina ceramic fiber, 1-3 pts. wt. zinc sulfide, 1.5-2 pts. wt. molybdenum trioxide, 2-3 pts. wt. aminosilane and 1-1.5 pts. wt. melamine. USE - Non-metallic anti-heat decay composite brake pad comprises 8-12 pts. wt. porous titanium carbide, 15-20 pts. wt. graphene modified styrene-acrylic emulsion, 8-12 pts. wt. porous silicon nitride ceramic powder, 9-11 pts. wt. flake graphite, 2-5 pts. wt. polytetrafluoroethylene, 9-12 pts. wt. sepiolite fiber, 4-5 pts. wt. magnesium oxide, 6-10 pts. wt. alumina ceramic fiber, 1-3 pts. wt. zinc sulfide, 1.5-2 pts. wt. molybdenum trioxide, 2-3 pts. wt. aminosilane and 1-1.5 pts. wt. melamine. ADVANTAGE - The method reduces wear with brake disc and improves brake pad. The porous silicon nitride ceramics have good thermal conductivity and self toughening effect. The brake pad has good thermal conductivity, longer service life and stable braking performance.
