Abstract

The invention discloses a combined type brake pad which comprises a steel sheet and a friction block. The friction block is prepared from, by weight, 100 parts of phenolic resin, 10-30 parts of carboxy-terminated liquid polybutadiene rubber, 10-20 parts of carboxylic crosslinked type acrylic rubber, 3-15 parts of modified graphite, 1-5 parts of polytetrafluoroethylene, 5-15 parts of molybdenum disulfide, 10-35 parts of sisal fiber, 15-35 parts of carbon fiber, 10-25 parts of aluminum fiber, 5-15 parts of molybdenum fiber, 5-10 parts of mica powder, 5-15 parts of zirconium silicide, 3-15 parts of silicon nitride, 1-5 parts of zinc stannate, 3-10 parts of octaphenyl oligomeric silsesquioxane, 5-15 parts of zirconium boride, 2-10 parts of graphene oxide, 3-12 parts of copper powder, 3-12 parts of boron carbide and 3-12 parts of acrylonitrile butadiene rubber powder. The combined type brake pad is good in high temperature resistance, excellent in heat resistance stability, high in wear resistance and long in service life.

Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to a combined brake pad. Background technique [0002] With the rapid growth of China's automobile production and sales, the level of China's automobile manufacturing and technology has also been steadily developed and improved. It is also a good opportunity and challenge for auto parts suppliers with independent intellectual property rights and research and development capabilities. Brake pads are one of the most common parts in automobiles. They are composed of steel sheets and friction substrates attached to the steel sheets. They are the most critical safety parts. Brake pads play a decisive role in all braking effects. However, the strength of the existing friction materials for brake pads is low, and the thermal stability is poor when the friction generates high temperature, and some raw materials are easily oxidized when the high temperature is generated, resulting in low...
