Problems solved by technology

The existing brake pads are mainly semi-metallic brake pads, the metal content of which exceeds 40%, and the heat conduction is too large, so the braking performance and braking comfort performance under high-speed conditions are not ideal
In addition, due to the high metal content, there is a lot of noise when braking, and the brake pads are prone to rust

Abstract

The invention discloses a low-metal ceramic-based drum-type brake pad and a preparation method thereof. The low-metal ceramic-based drum-type brake pad comprises the following raw materials by weight percent: 20 to 30 of ceramic adhesive, 10 to 20 of steel fibre, 15 to 30 of composite fibre, 0 to 5 of calcium carbonate crystal whisker, 2 to 5 of glass fibre, 0 to 5 of artificial graphite, 5 to 10 of crystalline flake graphite, 0 to 5 of chromium chromite, 2 to 5 of friction powder and 0 to 15 of composite filler. The preparation method comprises the steps of mixing, cold pressing, hot pressing, heat treatment, machining and ceramic treatment. The brake pad prepared by the invention has the characteristics of high-temperature resistance, high-pressure resistance, impact resistance and the like. Compared with a traditional product, the service life is enhanced by more than 2 times.

Description

technical field The invention belongs to the technical field of friction materials, in particular to a low-metal drum brake pad and a preparation method thereof. Background technique At present, the main raw materials of brake pads are adhesives, reinforcing fibers, lubricants and necessary regulators. The preparation process is material mixing-pressing-heat treatment-machining-painting-installation accessories-packaging. With the rapid development of the automobile industry, the speed of passenger cars is getting higher and higher, which also requires that the brake pads not only have good braking performance, but also have good heat resistance and good braking comfort. Existing brake pads are mainly semi-metallic brake pads, the metal content of which exceeds 40%, and the heat conduction is too large, so the braking performance and braking comfort performance under high-speed conditions are not ideal. In addition, due to the high metal content, there is a lot of noise wh...
