Embodiment Construction

[0065] Below in conjunction with the present invention is further described:

[0066] The preparation method of the ceramic-based friction material provided by the present invention realizes the molding of the friction material through the following steps, specifically as follows:

[0067] a. Design the formula of the product according to the product standard;

[0068] b. Weigh the designed formula according to the proportion;

[0069] c. Stir the inorganic polymer material, reinforcing fiber, friction modifier and others in the formula evenly; when the friction modifier is used in conjunction with the inorganic polymer material, first treat the acidic components on the surface of the friction modifier , wherein the friction modifier is iron oxide (iron red and iron black), copper powder, silicon carbide, corundum, graphite, molybdenum disulfide, iron sulfide, titanium dioxide, barite, cryolite, etc.

[0070] d. Stir the inorganic polymer materials and additives in the formu...

Abstract

The invention discloses a ceramic based friction material and a preparation method thereof. The ceramic based friction material has improved mechanical properties, fracture mechanical properties, thermal shock stability, stable chemical properties, excellent friction performance and wide field of use, and is composed of the following raw materials: an inorganic macromolecular polymeric binder, a reinforcing material, a friction performance conditioning agent and other materials. With the advantages of high temperature resistance, high pressure resistance and impact resistance, good anti-thermal decay performance, unique function, environmental protection and energy saving, light weight, no harm to a dual equivalent, long service life and strong environmental adaptability, the high performance friction material has a service life increased by over 2 times than that of existing products.

Description

Technical field: [0001] The invention relates to a preparation method of a friction material, in particular to a ceramic-based friction material and a preparation method thereof. Background technique: [0002] Friction material is a component material used in power machinery that relies on friction to perform braking and transmission functions. Any mechanical equipment and various moving vehicles must have braking or transmission devices. Friction materials are mainly used for braking and transmission of vehicles and power machinery. They are developing from single materials to composite materials. The quality of friction materials directly affects the reliability of machines and the safety of operators. With the development of science and technology, people have higher and higher requirements for the speed, load capacity and safety of transportation tools and power machinery. Such as airplanes, high-speed trains, heavy-duty trucks, cars, racing cars, motorcycles and other...
