Abstract

The invention provides an automobile brake pad which comprises a steel back and a friction material, wherein the friction material comprises the following materials in parts by weight: 1 to 10 parts of butylbenzene, 0.5 to 2 parts of cumyl hydroperoxide, 0.5 to 2 parts of epoxy resin, 1 to 15 parts of boric phenolic resin, 1 to 15 parts of polypropylene, 6 to 10 parts of nylon powder, 5 to 10 parts of boron nitride, 1 to 5 parts of dicumyl peroxide, 1 to 2 parts of sulphur powder, 1 to 2 parts of benzoic acid, 1 to 2 parts of stearic acid, 1 to 2 parts of boric acid, 50 to 60 parts of graphite, 5 to 8 parts of ceramic fibers, 0.5 to 1 part of potassium titanate, 1 to 2 parts of reduced iron powder, 1 to 2 parts of barium sulfate, 0.5 to 2 parts of bauxite, 0.5 to 2 parts of feldspar powder, 0.5 to 2 parts of zinc oxide, 0.5 to 2 parts of fluorite powder, 0.5 to 2 parts of silicon carbide and 0.5 to 2 parts of coumarone. The automobile brake pad is nuisanceless, pollution-free, noise-free, spark-free, wear-resistant and long in service life.

Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to an automobile brake pad used in automobiles. Background technique [0002] Earlier car brake pads were asbestos-type brake pads, but it is now found that asbestos has been confirmed by the medical profession to be a carcinogen. Every time you brake, the brake pads will emit millions of asbestos fibers into the air, and its needle-like limiters can easily enter the lungs and stay there, causing irritation and eventually leading to the occurrence of lung cancer. But in addition to the health hazards, there is another important problem with asbestos brake pads. Because asbestos is heat-insulating, its thermal conductivity is particularly poor. After repeated use of the brakes, the heat will accumulate in the brake pads. After the brake pads become hot, their braking performance will change, and the same friction and braking force will be produced. More braking times will be req...
