Abstract

The invention discloses a high temperature resistant resin-based friction material. The material is composed of the following raw materials of, by weight, 6-10 parts of modified phenolic resin, 6-8 parts of butadiene-acrylonitrile rubber powder, 4-8 parts of reinforced fibers, 10-14 parts of a friction modifier, 2-4 parts of an epoxy resin lubricant, and 12-14 parts of a filler. According to the high temperature resistant resin-based friction material provided by the invention, phenolic resin is modified through a cashew nut shell oil modifier, and the modified phenolic resin is more excellentin performance and applied to preparation of the resin-based friction material; the abrasion resistance, the high temperature resistance and the friction coefficient stability of the prepared resin-based friction material are improved; and sources of the raw materials are extensive, and the high temperature resistant resin-based friction material is applicable to industrial production and has good economical and social benefits.

Description

technical field [0001] The invention relates to the technical field of friction materials, in particular to a high temperature resistant resin-based friction material. Background technique [0002] Friction material is a component material used in power machinery that relies on friction to perform braking and transmission functions. It is widely used in automobiles, trains, aircraft and various construction machinery and equipment. Friction materials for automobiles are mainly composed of bonding, fiber reinforced materials, friction performance modifiers and fillers, which are mixed and pressed. With the development of vehicles in the direction of environmental protection, high speed and heavy load, people put forward higher requirements on the performance of automobile braking materials, especially in high temperature braking, the stability and safety of materials are very important. [0003] In the prior art, the friction material will thermally decompose when the workin...
