Material composition formula for automotive brake shell

Abstract

The invention relates to a material composition formula for an automotive brake shell. According to the material composition formula, the automotive brake shell is prepared from, by weight, 10-30 parts of carbon steel, 5-8 parts of sepiolite fiber, 2-5 parts of a modifying agent, 5-15 parts of fire retardant, 2-3 parts of polyethylene, 15-20 parts of hydrogenated acrylonitrile butadiene rubber, 3-5 parts of stearic acid, 1-2 parts of allyl alcohol, 1-2 parts of methyl hydrogen silicone oil, 12-24 parts of graphite, 4-6 parts of diacetyl peroxide, 3-5 parts of aluminum oxide, 1.2-1.6 parts of zinc oxide, 10-30 parts of organic silicon resin and 0.5-2 parts of an anti-aging agent. The automotive brake shell produced according to the matching has high heat dissipation performance, a large amount of heat produced by a brake can be dissipated, the phenomenon that the brake is scrapped due to high temperature is prevented, and the service life of the brake is prolonged.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to the material composition formula of an auto brake housing. Background technique [0002] The automobile brake housing is used to protect the brake and prevent other external parts from touching the brake, which may cause damage to the brake. However, due to the material of the brake housing, it is not easy to dissipate the heat generated by the brake during use, resulting in The heat of the brake itself accumulates a lot, and the brake is operated at high temperature for a long time, which will easily make the brake scrapped. Contents of the invention [0003] According to the deficiencies of the prior art, the present invention provides a material composition formula of an automobile brake housing that facilitates the heat dissipation of the brake housing. [0004] The present invention is achieved in this way. The material composition formula of the automobile brake housi...
