Abstract

The invention provides a brake gasket with bundle-type acrylic fibers. The brake gasket is prepared by components which comprise, by weight, 8% to 20% of resin, 5% to 15% of bundle-type acrylic fibers, 20% to 40% of friction strengthening agents, 7% to 15% of friction reduction agents, and 15% to 45% of padding. The brake gasket with the bundle-type acrylic fibers has the advantages of being stable in friction coefficient, small in heat fading, small in abrasion and light in weight, and therefore the bundle-type acrylic fibers are novel good strengthening materials which can replace asbestos and be used for the automobile brake gasket, and have a good application prospect.

Description

Technical field [0001] The present invention is a car brake lining without asbestos, glass fibers, and metal fibers. It involves a bracket lining for various car brake and deceleration. Background technique [0002] Traditional car brake lining slices are mainly based on phenolic resins or modified phenolic resins as adhesive materials, asbestos fiber, glass fiber, metal fiber, organic fiber, etc. as enhanced materials and various functional fillers as the main friction performance adjustment materials.Made by mixing, suppression, grinding processing and other processes.With the continuous improvement of automobile design and the continuous changes in the conditions of automobile use, the performance requirements of car brake lining are also increasing, especially as asbestos fiber on environmental pollution and human health hazards.: Article 4 of the Standard of the Structural, Performance and Test Method of the Automobile Brake System Article 4 The clear requirements of "brakin...
