The invention discloses a wear brake pad for heavy trucks. By a conventional compressing process, the wear brake pad is made of the following materials, by weight, 10-20% of thermosetting resin, 5-12% of graphite, 5-7% of zirconium silicate, 8-11% of hydroxyapatite, 10-20% of epoxy resin, 3-6% of friction improving agent, 7-14% of coke dust, 6-12% of calcium silicate ceramic powder, 5-12% of cashew-nut oil frictional powder, 3-5% of calcium oxide, 5-7% of molybdenum disulfide and the balance being nitrile rubber. Abrasion of the wear brake is reduced, and the wear brake pad works stably without generation of noises, has good heat conductivity and stable braking performance, and is safe and reliable. According to the special characteristic of wear resistance of the ceramic material, the wear rate of the wear brake pad is reduced effectively on the basis of stabilizing friction coefficient of friction materials, and thus the service life of the friction materials is prolonged.
Description
Technical field [0001] The invention involves the field of composite materials, and specially involves a carriers of carriers. Background technique [0002] With the rapid development of the automotive industry, automobile ownership is also expanding.As the key component of the car brake system, the car brake pads need to meet the requirements of braking safety and reliability, running smoothly without noise.At present, the type of friction material for domestic vehicle can be divided into three types: 1) asbestos: its manufacturing cost is low and the process is simple; it is mainly used for agricultural vehicles and engineering machinery.The disadvantages of its existence: asbestos are harmful to the human body, pollute the environment, severe high temperature and heat decline, poor braking performance, and small safety factor. This product has decreased year by year and is eliminated products.2) Semi -metal base: It has good temperature resistance and resistance at high temper...
