Abstract

The invention discloses a passenger car friction material suitable for a high speed of 200 kilometers and a high deceleration speed of 0.8 G and a preparation method of the passenger car friction material. The preparation method comprises the following steps that firstly, a steel backing is treated; secondly, friction materials are mixed, wherein by mass part, steel fibers, self-made friction powder, granular potassium hexatitanate, aramid fibers, mineral fibers, tin sulfide, graphite powder, coke powder, zirconium silicate/zirconium oxide/barium sulfate composite powder, calcium hydroxide and mica are added into a high-speed mixer, after mixing, modified resin is added, mixing is conducted for 30-60 min at the speed of 400-500 r/min, and a friction material mixture is obtained; and thirdly, a brake pad is prepared through hot pressing, wherein the obtained brake pad is machined, subjected to surface plastic spraying treatment, marked and assembled, and the passenger car friction material suitable for the high speed of 200 kilometers and the high deceleration speed of 0.8 G is obtained. The friction material has a high deceleration speed and excellent wear resistance.

Description

technical field [0001] The invention relates to the field of friction materials, in particular to a friction material for passenger cars suitable for a high speed of 200 kilometers and a high deceleration of 0.8G and a preparation method thereof. Background technique [0002] Friction material is a material that converts the kinetic energy of the car into heat energy, thereby reducing the speed of the car. The performance of the friction material fundamentally determines the quality of the car's braking performance and directly affects the lives of the people. With the development of the automobile industry, friction materials have also gone through stages such as asbestos friction materials, semi-metallic friction materials and organic non-asbestos friction materials, which mainly solve the environmental pollution problems of some raw materials in friction materials, the mechanical properties of friction materials, Thermal performance issues of friction materials and other ...
