Abstract

Main components of a low-noise ceramic brake pad comprise ceramic fibers, sisal fibers, polyacrylonitrile fibers, FKF complex mineral fibers, boric acid modified phenolic resin, a titanate coupling agent, chlorinated paraffin, superfine fully-vulcanized powdered rubber, a brown fused alumina friction increasing material, flaky aluminium powder, nanoscale molybdenum disulfide, mica, calcium sulfate whiskers and titanium dioxide whiskers. Starting from reduction of the noise of the ceramic brake pad, the friction noise is reduced remarkably while the high friction performance of the ceramic brake pad is met by strictly controlling the use quantities and matching of enhanced fibers, adhesives, filler, friction powder and lubrication materials and adding organic enhanced fibers.

Description

technical field [0001] The invention relates to a brake pad for automobile braking, in particular to a low-noise ceramic brake pad and a preparation method thereof. Background technique [0002] Improving safety performance, reducing environmental pollution and noise pollution, and prolonging service life are general trends in the development of friction materials. my country's automobile brake pad industry is facing two major transformations: environmental protection and high performance. Environmentally friendly high-performance brake pads should not only meet the requirements of small high-temperature recession, low wear rate, and stable friction coefficient, but also have small vibration and low noise. The performance characteristics of environmental protection and humanization put forward higher requirements for friction material formulation technology, raw material processing technology, mixing preparation technology, hot pressing technology, heat treatment technology a...
