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
The present invention relates to a kind of making method of automobile brake sheet, particularly relate to a kind of making method of non-metallic automotive braking brake block.
Background technique
Automobile brake sheet is that Control of Automobile is travelled and ensured automobile critical function part safe in utilization.The automobile brake sheet that uses all is that metal is made at present, and owing to the friction heat release, the brake block metal can soften when long-time brake, and intensity significantly reduces, and can cause the inefficacy of brake.
Summary of the invention
The objective of the invention is to overcome existing metal automobile brake block when long-time brake because the friction heat release, metal softening causes the shortcoming of the inefficacy of brake, the making method of the higher non-metallic automotive brake block of a kind of softening temperature is provided, this method is a main raw material with silica and silicon nitride, its brake block is high temperature resistant, be difficult for softening, can guarantee ride safety of automobile.
The objective of the invention is to be achieved through the following technical solutions:
A kind of making method of automobile brake sheet, this method may further comprise the steps:
(1). silicon oxide powder is crushed to fineness 1200 orders;
(2). silicon nitride powder is broken to fineness 1600 orders;
(3). the silica after levigate, alpha-silicon nitride powders are mixed by mass ratio 1:0.05～0.10, be heated to 1200 ℃, powder after the heating is added pressurization 10mpa in 50cm * 50cm * 20cm mould, pressurize to powder temperature is reduced to 700 ℃, and the product that continues after nature is lowered the temperature is inorganic automobile brake sheet raw material;
(4). according to braking automobile design needs the above-mentioned raw material that obtains is processed into suitable shape and is final products.
Advantage of the present invention and effect are:
Production technology of the present invention is simple, fabricating cost is low, can extensively promote; Its brake block is high temperature resistant, is difficult for softening, and can guarantee ride safety of automobile.
