Novel friction material and preparation method thereof

Abstract

The invention discloses a novel friction material which is prepared from the following materials: 5 to 10 parts of butanone, 5 to 10 parts of methylbenzene, 1 to 5 parts of nitrile rubber buna, 0.5 to 1.5 parts of paste resin, 5 to 8 parts of polyvinyl chloride, 0.2 to 0.7 part of white carbon black, 0.8 to 1.5 parts of zinc oxide, 0.4 to 1 part of stearic acid, 0.1 to 0.8 part of anti-aging agent, 0.1 to 0.5 part of calcium carbonate, 1 to 1.5 parts of adhesive, 0.7 to 1.3 parts of initiator and 8 to 15 parts of ceramic fiber. Most of existing friction materials are rubber or materials added with metal and the like, at present, the friction material is a novel friction material which uses natural and artificial fibers and has good wear resistance and skid resistance, the use effect in the actual use process is improved, meanwhile, by adding ceramic fibers, the overall strength can be improved, and the service life of the friction material is prolonged. The novel friction material can effectively prevent the surface of the novel friction material from cracking and even breaking under the condition of high temperature, has better compression-resistant and anti-aging effects, and has better mechanical properties, good tensile strength and high impact strength by adding polyvinyl chloride.

Description

technical field [0001] The invention relates to the technical field of friction materials, in particular to a novel friction material and a preparation method thereof. Background technique [0002] In some conveying equipment, the corresponding roller body is usually installed for transmission and transmission. The roller body usually requires a large tension, so the top roller has a relatively large roughness, and a layer of friction material is usually wrapped on the surface of the roller body. [0003] The deficiencies of existing technology: [0004] Most of the existing friction materials are made of rubber or internally added metal and other materials. Although they have certain mechanical properties, tensile strength and impact strength, in some harsh environments with high temperature and corrosion, the surface of new friction materials is prone to cracks or even cracks. Fracture, while the surface wear resistance and poor skid resistance. Contents of the inventio...
