Abstract

The invention discloses a hydraulic disc brake lining and a preparation method thereof. The hydraulic disc brake lining comprises the following components of, by weight, 18-22 parts of steel fibers, 13-18 parts of modified phenolic resin, 2-5 parts of powdery nitrile rubber, 13-18 parts of graphite powder, 35-39 parts of filler, 1-4 parts of FKF composite mineral fiber, 1-4 parts of zinc stearate,3-7 parts of silicon carbide, 6-10 parts of zirconium diboride, 2-5 parts of molybdenum silicide and 2-6 parts of zirconium carbide. The preparation method comprises the following steps that S1, primary mixing and material proportioning and preparing are performed; S2, secondary mixing and material proportioning and preparing are performed; S3, pre-forming is performed; S4, hot-pressing forming is performed; S5, heat treatment is performed; and S6, a product subjected to heat treatment undergoes grinding and drilling, and then is prepared into a finished product through machining. The hydraulic disc brake lining has the advantages of being good in heat resistance, water resistance and high temperature heat fade resistance, and capable of improving the high-temperature brake friction coefficient; and the preparation method has the advantages of being high in preparation precision and more accurate in size.

Description

technical field [0001] The invention relates to the technical field of brake linings, in particular to a hydraulic disc brake lining and a preparation method thereof. Background technique [0002] Brake pads and linings are part of automobile friction materials, and are key safety parts in the automobile industry. The starting, braking and parking of automobiles are inseparable from friction materials. The quality and quality of friction materials are directly related to life and property. Safety. [0003] In this regard, more than ten years ago, the Ferodo company in the UK began to produce asbestos-free automobile brake linings (referred to as brake pads); 70% of TEL companies in the UK are asbestos-free brake linings, mainly based on metal bases. brake products for new models. Most of the cars in the United States use semi-metallic linings, which account for 80% of the cars and vans. At present, asbestos brake linings still occupy a considerable proportion in my country...
