Abstract

The invention provides an automobile brake pad. The automobile brake pad is prepared from, by weight, 3%-25% of potassium hexatitanate whisker or sodium hexatitanate whisker, 0-20% of aluminum silicate hollow sphere, 0.1%-15% of brown aluminum oxide, 0.1%-20% of carbon fiber, 3%-30% of phenolic resin and 5%-50% of padding. The invention further provides a preparation method of the automobile brake pad. The potassium (sodium) hexatitanate whisker reinforced resin matrix brake pad is low in noise and heat fading performance, a mating plate is not likely to be damaged, and the wear rate is very low; and the service life of a product can be greatly prolonged, resource consumption can be reduced, and the influence to the environment is reduced. Raw materials selected in the automobile brake pad are common and easy to obtain, production cost can be effectively reduced, and great significance in increasing the added value of domestic rich mining deposits is achieved.

Description

technical field [0001] The invention belongs to the field of materials science and relates to a brake pad, in particular to an automobile brake pad and a preparation method thereof. Background technique [0002] The brake pad is a key component in the braking system. It rubs against the brake disc (or brake drum) to form a frictional couple, generates braking torque, and converts the kinetic energy of the car into heat energy. The overall performance of the brake pads will directly affect the reliability and stability of the braking system. Due to the rapid development of my country's automobile industry and the increasing emphasis on environmental protection, the requirements for brake friction materials are becoming more and more stringent. For example, stable friction coefficient, excellent thermal conductivity, low thermal decay, certain high-temperature mechanical strength, excellent wear resistance, less wear on the counterpart, no noise, no pollution to the environme...
