Abstract

The invention provides a low-noise friction material and a preparation method thereof, which solves the problem that the existing brake pad friction material will generate relatively large noise during the braking process, control the braking noise is unstable, and cannot fully meet the performance requirements of automobiles technical issues. Its components include polytetrafluoroethylene powder and filler material, the filler material includes inorganic filler and polymer filler, the inorganic filler is a solid lubricant, and the polymer material is a material that does not damage the dual surface and is easy to be machined. . The invention can be widely used in braking system.

Description

technical field [0001] The invention relates to a friction material and a preparation method thereof, in particular to a low-noise friction material and a preparation method thereof. Background technique [0002] With the increase of private cars and the improvement of people's living standards, brake pads are an important component of automobile safety performance. Under the premise of ensuring safety, the comfort, sensitivity and stability of braking have gradually become important indicators of brake pad performance. Among them, the comfort level has attracted more and more people's attention, and the most obvious influence on the comfort level of brake pads is noise. Noise is currently the most difficult problem for all friction material manufacturers in the world to solve. Most manufacturers of friction materials have very unstable control over the braking noise of brake pads, which cannot fully meet the performance requirements of automobiles. [0003] Noise is gener...
