Abstract

The invention discloses a car disc type brake pad. The car disc type brake pad is characterized by being formed by the following components in parts by weight according to the conventional brake pad pressing method: 10-25 parts of cashew nut shell oil-modified phenolic resin, 5-15 parts of graphite, 10-20 parts of coal ash, 6-10 parts of calcium carbonate, 3-8 parts of grinding composition, 3-20 parts of coke dust, 5-10 parts of potassium feldspar powder, 10-16 parts of chemigum, 1-2 parts of molybdenum disulfide, 5-20 parts of mica and the balance of epoxy resin. In the car disc type brake pad, the pollution can be reduced and the environment can be purified by the new purpose of the cashew nut shell oil-modified phenolic resin in the manufacturing process of the brake pad, waste can be fully utilized, the resources and the energy can be recycled to create the economical benefits, and the car disc type brake pad accords with the basic state policy of energy conservation and emission reduction, resource utilization of waste and sustainable development.

Description

technical field [0001] The invention relates to an automobile disc brake pad. Background technique [0002] The most important safety system on a car is the braking system, and all braking components are safety components. Brake pads are one of the most important links in the entire braking system, which will directly affect the reliability of the entire braking system. Brake pads and brake discs (or brake drums) rub against each other to form a frictional couple, generate braking torque, and convert the kinetic energy of the car into heat energy. When braking, the temperature of the brake pads and brake discs will rise by 300-400 °C. Brakes Brake pads and discs (or drums) are the most stressed components in a vehicle, subject to extreme heat, mechanical and chemical stress. In addition, brake pads are exposed to external environmental influences such as moisture, dust and stains for a long time, which will affect their performance and life.
