Problems solved by technology

Currently used car brake pads are all made of metal. When braking for a long time, due to friction and heat generation, the metal of the brake pads will soften and the strength will be greatly reduced, which will cause the brakes to fail.

Embodiment 1

[0013] The silicon oxide powder was pulverized to a fineness of 1200 mesh, and the silicon nitride was pulverized to a fineness of 1600 mesh. Mix the finely ground silicon oxide and silicon nitride powders evenly at a mass ratio of 1:0.05, heat to 1200°C, put the heated powder into a 50cm×50cm×20cm mold, pressurize at 10mpa, and keep the pressure until the temperature of the powder drops. to 700°C. The product after continuing to cool down naturally is the raw material of inorganic automobile brake pads, and the raw material obtained above is processed into a suitable shape according to the design requirements of automobile brakes, which is the final product. Suitable for ordinary small cars.

Embodiment 2

[0015] The silicon oxide powder was pulverized to a fineness of 1200 mesh, and the silicon nitride was pulverized to a fineness of 1600 mesh. Mix the finely ground silicon oxide and silicon nitride powders evenly in a mass ratio of 1:0.07, heat to 1200°C, add the heated powders into a 50cm×50cm×20cm mold and pressurize at 10mpa, keep the pressure until the powder temperature drops to 700°C. The product after continuing to cool down naturally is the raw material of inorganic automobile brake pads, and the raw material obtained above is processed into a suitable shape according to the design requirements of automobile brakes, which is the final product. It is suitable for medium-sized vehicles with a load capacity of 1.5-5 tons.

Embodiment 3

[0017] The silicon oxide powder was pulverized to a fineness of 1200 mesh, and the silicon nitride was pulverized to a fineness of 1600 mesh. Mix the finely ground silicon oxide and silicon nitride powders evenly at a mass ratio of 1:0.1, heat to 1200°C, add the heated powder into a 50cm×50cm×20cm mold and pressurize at 10mpa, and keep the pressure until the powder temperature drops to 700°C. The product after continuing to cool down naturally is the raw material of inorganic automobile brake pads, and the raw material obtained above is processed into a suitable shape according to the design requirements of automobile brakes, which is the final product. It is suitable for heavy-duty vehicles with a load capacity of 5-35 tons.

Abstract

A making method for a brake shoe of an automobile relates to a making method of the brake shoe of the automobile. The method comprises the following steps: (1) the silica powder is crushed to the fineness of 1200 grids; (2) the silicon nitride is crushed to the fineness of 1600 grids; (3) the milled silica and silicon nitride powder is uniformly mixed according to the mass ratio of 1: 0.05-0.10 and heated to 1200 DEG C; the heated powder is poured into a die (50cm multiplied by 50cm multiplied by 20cm) under the pressure of 10MPa; the pressure is maintained until the temperature of the powder reduces to 700 DEG C, and the temperature keeps reducing naturally to get the product which is the raw material of the inorganic automobile brake shoe; (4) the obtained raw material is processed to suitable shape in order to get the final products according to the requirement of the design of the automobile brake. The invention has simple production process and low manufacture cost, and can be widely generalized; the brake shoe resists high temperature and is not easy to be softened, which can ensure the driving safety of the automobile.

Description

technical field [0001] The invention relates to a method for manufacturing an automobile brake pad, in particular to a method for manufacturing a non-metallic automobile brake pad. Background technique [0002] Automobile brake pads are important functional parts to control the driving of the car and ensure the safety of the car. The currently used automobile brake pads are all made of metal. When braking for a long time due to friction and heat generation, the metal of the brake pads will soften and the strength will be greatly reduced, which will cause the brakes to fail. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcoming of the existing metal car brake pads due to frictional heat release and metal softening that cause brake failure during long-term braking, and to provide a method for making a non-metallic car brake pad with a high softening temperature. With silicon oxide and silicon nitride as the main raw materials...
