Problems solved by technology

Among them, although the steel fiber non-asbestos brake pad can meet the basic braking performance, it has the advantage of low cost. When used on the front brake, the brake is weak, has affinity with the dual (cast iron or steel), and the friction coefficient is stable. Not high, the content of Mn and P in the steel wool is high, which is not conducive to frictional couples and other shortcomings

Abstract

The invention relates to a material for preparing a steel fiber brake pad, which is prepared by the ingredients by weight percentage: 8-12% of phenolic resin, 5-15% of frictional powder, 2-5% of nitrile rubber, 5-10% of aluminium oxide, 15-25% of chromite, 5-8% of feldspar, 6-10% of crushed steel cotton fiber, 10-15% of acerose wollastonite powder, 15-20% of tire powder, 2-5% of magnesium oxide and 15-20% of lignin fiber. The steel fiber brake pad prepared by the material has the advantages of good brake performance, stable friction factor, no damage for antithesis, high heat conductivity, good heat dissipation in the friction process and good plasticity, and crushed steel cotton fiber has the advantages of high intension and low cost and can meet general brake.

Description

technical field [0001] The invention relates to a material for a brake pad, in particular to a material for preparing a steel fiber brake pad. Background technique [0002] Brake pads (brake pads) are one of the indispensable components in brakes, clutches and friction transmissions of various machinery and equipment. Its most important feature is that it can absorb kinetic energy, convert kinetic energy into heat and dissipate it into the air, the brake pad itself has no destructive wear, and the friction parts are not damaged. [0003] Motor vehicle brake pads often use non-metallic and semi-metallic friction materials, usually made of rubber and resin as the bonding matrix, and metal and non-metallic powders are added as fillers, and high-temperature resistant fibers are often added to the material. Such as asbestos and some minerals and ceramic fibers. Most of the friction materials use asbestos as the main component. Because asbestos is very harmful to human health, ...
