Abstract

The invention discloses a friction granule and the granulation technology thereof. Firstly, resin, toughener, rubber, antifriction, fiber, molding agent, filling, and friction material waste machining material are weight according to a certain proportion, mixed and added into a mixing plant to be stirred by adding water, so a wet mixture is obtained; granulation is carried out on the wet mixture on a granulation device to obtain a granular matter; the granular matter is roasted for many hours under the temperature of 100-200 DEG C to obtain a dried granular material; and at last, the dried granular material is screened according to the requirement to obtain the granular material with needed grit number. The invention utilizes waste materials, reduces the production cost and facilitates the environment protection; in addition, the wearable performance, the vibration resistance and the anti-attenuation of the obtained friction granule are all improved; the brake is sensitive and stable with little noise; and the damage caused for a braking disc drum is little.

Description

Technical field: [0001] The invention relates to the technical field of friction material manufacturing, in particular to a friction particle and a water-added manufacturing process thereof. Background technique: [0002] At present, the friction material industry, which is widely used, develops rapidly with the development of the automobile and machinery industries, and the requirements for friction material products are getting higher and higher. For this reason, a new raw material of friction particles has been produced. Friction particles refer to the multi-component compound granular raw materials used in the production of friction materials, which play a role in improving the performance of friction materials. Friction particle technology is a new technology emerging at home and abroad. The process of preparing friction particles at home and abroad mostly adopts rubber mixing method or slurry method, that is, it is made on special equipment through multiple processes,...
