Embodiment Construction
[0029]In terms of parts by weight, weigh 5-7 parts of titanium powder, 5.0-5.5 parts of carbon powder, 10-11 parts of aluminum powder and 12-13 parts of iron powder into a three-dimensional mixer and mix at a speed of 200-300r / min 5 to 6 hours to prepare the solid mixture, in parts by weight, put 3 to 5 parts of the solid mixture, 1 to 2 parts of urea granules and 10 to 11 parts of absolute ethanol in a three-dimensional mixer and mix for 5 to 6 hours to obtain the solid mixture. Liquid mixture; put the above solid-liquid mixture into a muffle furnace, heat up to 220-230°C and preheat for 60-70 minutes. The iron powder is mixed according to the mass ratio of 1:2 to prepare the ignition powder, and the ignition powder with a mass of 50-60% of the solid-liquid mixture is put into the muffle furnace, and the combustion reaction is 40-50 minutes. The metal composite product is obtained, and it is set aside; in parts by weight, 3 to 5 parts of graphite powder, 1.5 to 1.8 parts of p...

Abstract
The invention relates to a preparation method of a high-temperature-resistant and wear-resistant brake pad, belonging to the technical field of brake pad preparation. In accordance with that invention, titanium pow, Carbon powder, aluminum powder and iron powder are mixed, A metal composite product is prepare by adding urea and absolute ethanol, oxidizing graphite powder, A modified mixture is prepared by reduction and modification, A metal composite product of that mix slurry, A high-temperature-resistant and wear-resistant brake pad is obtain by mixing that modify mixture and pressing the mixture into a mold, Volatilization of urea particles, A metal mixture is microscopically porou, in the pores of the metal mixture filled with the modified nano-graphene, making the microstructure of the metal mixture stronger, The impact resistance and mechanical strength of the brake pads are effectively improved, and the high temperature resistance and strength of the metal mixture can be greatlyimproved by the introduction of titanium, and the high temperature resistance of the metal mixture can be further improved by the modified graphene, and the carboxyl and ester groups in tung oil canimprove the mechanical strength and wear resistance of the brake pads, so that the brake pads have a broad application prospect.
Description
technical field [0001] The invention relates to a method for preparing a high-temperature-resistant and wear-resistant brake pad, and belongs to the technical field of brake pad preparation. Background technique [0002] At present, with people's pursuit of modern quality of life, cars have become an indispensable daily necessities in family life. Cars have entered the homes of ordinary people in large numbers. The performance of cars, especially the braking performance, has become a common concern of the society. Because the car brake pad is a key component in the car brake, the performance of the brake pad is directly related to the reliability, stability and safety of the car's operation. [0003] The brake pad is composed of a back plate, an adhesive layer and a friction block, and is the most critical safety part in the automobile braking system. [0004] When braking, it is squeezed on the brake disc or drum to generate friction, so as to achieve the purpose of vehicl...
