Embodiment Construction

[0039] The kudzu fiber-reinforced environmentally friendly high-performance car brake pads use rare earth modified phenolic resin as a binder, kudzu fiber, aramid pulp, and FKF composite mineral fiber as reinforcement materials, and add ultra-fine fully vulcanized powder rubber, calcined petroleum Coke, strong foam iron powder, and expanded graphite are used as friction performance regulators to improve and enhance the friction performance of brake pads. In order to improve production efficiency and qualified rate of brake pads, a one-step molding process is adopted to prepare brake pads. Under high temperature and high speed, the product has no heat expansion, no thermal cracking, no heat decay, no pollution, long service life, good safety and stability, and its main performance indicators have reached the relevant national standards, and it is expected to become a new generation of environmental protection products. Brake pads for high-performance cars.

Abstract

A kudzu fiber reinforcement environmentally friendly high-performance brake sheet comprises natural kudzu fibers serving as a material skeleton, aramid pulp, FKF composite mineral fibers, phenolic resin with rare-earth modification, friction performance conditioning agents and packing; the brake sheet comprises, by weight, 30-40 parts of reinforced fibers, 8-15 parts of adhesives, 10-15 parts of the friction performance conditioning agents and 25-35 parts of the packing. After alkali treatment and ultrasonic combined treatment, the kudzu fiber has powerful toughness, is high in breaking strength, belongs to renewable resources and is green and free of poison, is allowed to be naturally degraded and is environmentally friendly. Due to the kudzu fibers, the brake sheet has the advantages of being high in product strength, moderate in elasticity modulus, good in heat resistance, light in weight, small in expansion coefficient and abrasion, short in brake distance, good in chemical stability and heat fading performance and free of environment pollution.

Description

technical field [0001] The invention relates to a brake pad for automobile braking, in particular to a kudzu fiber-reinforced environmentally friendly high-performance brake pad and a preparation method thereof. Background technique [0002] At present, the brake pads produced in China account for 5% of the world's total demand, and within the next five years, the brake pads produced in China will account for 45% of the global total demand. In the next five years, 1.44 billion sets of brake pads will be produced in China. my country's automobile brake pad industry is facing two major transformations: environmental protection and high performance. Environmentally friendly high-performance brake pads should not only meet the requirements of small high temperature recession, low wear rate, and stable friction coefficient, but also have small vibration, low noise, Environmentally friendly and humanized performance characteristics such as less ash fall, all of which put forward h...
