Embodiment Construction

[0017] In the specific implementation process of this case, antimony sulfide TiS was selected as the friction enhancer.

[0018] An example is:

[0019] Artificial graphite, fiber, resin, nano-clay, latex, friction enhancer, sodium silicate, and urotropine are composed according to the following proportions, and the weight percentage content of each component is: artificial graphite is 40%, fiber is 30% , 2% resin, 8% nano-clay, 8% latex, 8% antimony sulfide, 3% sodium silicate, and 1% urotropine. Stirring and mixing are at normal temperature, and the mixing time is 30 minutes. The baking temperature is 120° C., and the baking time is 50 minutes. The size of the granulation is 8-10 mesh.

[0020] The weights of the three fibers of cellulose fiber, carbon fiber and mineral wool in the said 30% component fiber are equal.

[0021] Another example is:

[0022] Artificial graphite, fiber, resin, nano-clay, latex, friction enhancer, sodium silicate, and urotropine are composed ...

Abstract

The invention relates to a friction material to be mounted in brake components and other devices for producing friction, in particular a kind of friction particles comprising the following constituents (by weight percentage): artificial graphite 40-65%, fabric 20-40%, resin 2-15%, nano mortar 3-15%, latex 5-20%, rubbing agent 3-15%, sodium silicate 1-10% and hexamethylene tetramin 0.5-2%.

Description

technical field [0001] The present invention relates to friction material, particularly a friction particle, for installation in various brake components and other friction-generating equipment. Background technique [0002] Various brake components such as drum brake components, disc brake components and similar brake components used on automobiles and other transportation vehicles and mechanical brakes are well known. These components perform functions, often at high The braking rate slows down or stops high-speed moving vehicles and moving parts. During braking, most or almost all of the kinetic energy is converted into frictional heat on the surface of the friction material. This braking process also often results in very high operating temperatures in or in the friction material. [0003] The friction particles currently produced in my country are generally single raw material graphite. However, the friction material using graphite as friction particles has the defec...
