Problems solved by technology

With the prohibition of asbestos, more and more asbestos-free formulas have been developed, because the friction materials of brake pads generally have to go through two processes of cold pressing preforming and hot pressing forming, and asbestos substitute materials do not have good dispersion and Absorptivity, resulting in cold-pressed preformed blanks th

Abstract

The invention discloses a non-asbestos brake block containing animal fibers. The non-asbestos brake block comprises, by weight, 14-16% of modified phenolic resin, 20-28% of fiber material, 53-61% of filling material and 5-8% of the animal fibers. The animal fibers are composed of one or more of sheep wool, cony hair, camel hair, goat hair, mohair, yakwool and silk, and the fiber material is composed of one or more of mineral fibers, glass fibers and paper fibers. The invention further discloses a manufacturing method for the non-asbestos brake block containing the animal fibers. The non-asbestos brake block containing the animal fibers is good in high-temperature resistance and abrasive resistance, the non-asbestos formula can have good strength in the cold-pressing performing process so that the purpose of transferring can be achieved, and the non-asbestos brake block containing the animal fibers is simple in manufacturing method and low in cost.

Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to an asbestos-free brake pad containing animal fibers and a preparation method thereof. Background technique [0002] Brake pads are also called brake pads or brake pads. In the braking system of a car, brake pads are the most critical safety parts and play a decisive role in the braking effect. Brake pads are generally made of steel plates, adhesive insulation layers and friction block composition. The friction block is composed of friction material and adhesive. When braking, the friction block is squeezed on the brake disc or brake drum to generate friction with it, so as to achieve the purpose of decelerating and braking the vehicle. It can be seen that the friction block determines the braking performance of the brake pad at high speed and high temperature. The friction material is an important part of the brake pad in the manufacturing process and use process. [0003] T...
