Problems solved by technology

[0004] However, the brake pad of this invention is exposed to the outside for a long time during use, and the working environment is relatively harsh. It is often subjected to the test of high temperature and low temperature intermittently. When it is parked outdoors for a long time or is located in a humid environment, its steel surface It is easy to generate some rust stains, and these rust stains will cause the brake pads to stick to it, seriously affecting the braking effect and braking comfort

Abstract

The invention relates to a compound brake pad, a preparation method and an application thereof. The compound brake pad is prepared from the following raw materials in parts by weight: 2-20 parts of potassium titanate whiskers, 5-20 parts of zinc powder, 1-15 parts of calcium hydroxide, 0.5-10 parts of friction powder, 1-15 parts of aramid fibers, 2-18 parts of resin, 5-20 parts of copper wool and5-30 parts of ceramic fibers. By combining the zinc powder with calcium hydroxide, the zinc powder is high in oxidizing property and can be used as a protecting pole of the brake pad in a braking process, and all the charges are transferred to the brake pad while the zinc powder and calcium hydroxide are reacted, so that a brake disc is prevented from being corroded, and the condition that the brake disc and the brake pad are adhered due to rusting of the brake disc is avoided.

Description

technical field [0001] The invention belongs to the technical field of auto parts, and in particular relates to a composite brake pad and its preparation method and application. Background technique [0002] Friction material is a component material used in power machinery that relies on friction to perform braking and transmission functions. It mainly includes brake linings (brake pads) and clutch facings (clutch plates). Brake pads are used for braking and clutch plates are used for transmission. Any mechanical equipment and various moving vehicles must have braking or transmission devices. Friction material is a critical component on this braking or transmission. Its main function is to absorb or transmit power through friction. For example, the clutch plate transmits power, and the brake plate absorbs kinetic energy. They enable mechanical equipment and various motor vehicles to work safely and reliably. So the friction material is a widely used and even critical m...
