Abstract

The invention discloses a car brake block with a piemarker fiber and a preparing method of the car brake block. The car brake block comprises the natural piemarker fiber, aramid fiber pulp, rare-earth modified phenolic resin, a friction performance modifier, padding and the like, and comprises, by weight, 30-35 parts of reinforced fiber, 13-16 parts of binding agent, 9-12 parts of friction performance modifier and 40-45 parts of padding. The piemarker fiber on which the alkali treatment and ultrasonic treatment are carried out is low in price, light, high in specific strength, specific modulus and tensile strength and good in abrasion resistance and has other superior properties, and belongs to renewable resources. The car brake block prepared under the optimal technological condition and mixed with the piemarker fiber has a stable friction coefficient, a good brake effect and brake smoothness, is low in noise, good in comfort and friendly to the environment and is an ideal environment-friendly friction material.

Description

technical field [0001] The invention relates to the technical field of friction materials for car braking, in particular to a car brake pad mixed with avelphine fibers and a preparation method thereof. Background technique [0002] Friction materials are functional accessories used in automobiles and machinery for transmission, braking, deceleration, steering, parking, etc. According to the function and installation position, it is mainly divided into brake lining and clutch facing. In the past 20 years, the composition and manufacturing process of the friction materials used in vehicles represented by automobiles have undergone significant changes. The new friction materials have better resistance to thermal degradation, longer life and are more conducive to environmental protection and human beings. healthy. Friction materials are key safety parts in the automobile industry. The starting, braking and parking of automobiles are all inseparable from friction materials. The...
