Abstract

The invention relates to preparation of a friction material in the field of automobile industry, in particular to a copper-free ceramic brake pad, and the friction material of the copper-free ceramic brake pad consists of the following raw materials: an adhesive, a reinforcing material, a friction performance regulator and a filler. The brake pad has the advantages that the friction material formula is designed by utilizing the advantages of good heat resistance, heat stability, water resistance and the like of the ceramic fibers, the internal structure of the material is changed, and the comprehensive practical performance of the brake pad is improved; the brake pad has no heat fading phenomenon at high temperature, the friction coefficient is stable, the product abrasion is small, the brake is comfortable in the use process, no noise is generated, and the service life is more than 70,000 kilometers; and the brake pad is qualified through through the American LINK3900 rack TP2044 standard detection, the car brake pad has the advantages of being stable in safety performance and low in cost, and in addition, and there is no need to improve an existing processing technology, so that the production cost and the transformation cost are greatly saved.

Description

technical field [0001] The invention relates to the preparation of friction materials in the field of automobile industry, in particular to a copper-free ceramic brake pad. Background technique [0002] In recent years, the rapid development of the automobile industry has injected a strong force into my country's economic construction, driving the development of a large number of domestic industries, especially after 2005, the popularity of the automobile market has exceeded people's imagination, and the growth of total output value In a straight line trend. With the rapid development of the automobile industry, my country's automobile brake friction material market is also active. The demand for automobile brake pads is increasing year by year, and the high-precision and high-quality production of automobile brake pads is needed to support the safety of automobile driving. [0003] Automobile brake is a key component to ensure driving safety. It is designed to reduce the sp...
