Abstract

The invention discloses a high-temperature-resistant resin-based friction material. The high-temperature-resistant resin-based friction material is composed of, by weight, 6 to 10 parts of modified phenolic resin, 6 to 8 parts of nitrile rubber powder, 4 to 8 parts of reinforcing fiber, 10 to 14 parts of a friction modifier, 2 to 4 parts of an epoxy resin lubricant, and 12 to 14 parts of a filling material. According to a preparation method, a cashew nut shell oil modifier is adopted for modification of phenolic resin, so that the performance of the modified phenolic resin is better; the modified phenolic resin is used for preparing the high-temperature-resistant resin-based friction material, so that the friction resistance, the high temperature resistance, and the friction coefficient stability of the high-temperature-resistant resin-based friction material are improved; the raw materials are widely available; the high-temperature-resistant resin-based friction material is suitable for industrialized production; and excellent economical and social benefits are achieved.

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...
