Problems solved by technology

However, the strength of the existing friction material for the friction plate is low, and the thermal stability is poor when the friction generates high temperature. Some raw materials are easily oxidized when the high temperature is generated, resulting in a low service life of the friction material. High temperature resistance, poor thermal stability, not durable, thus affecting the performance of brake pads

Abstract

The invention discloses a high temperature-resistant heavy-duty vehicle brake disc. The high temperature-resistant heavy-duty vehicle brake disc comprises a steel sheet and a friction base material pasted on the steel sheet, raw materials of the friction base material comprise phenolic resin, hydroxyl-terminated liquid polybutadiene rubber, acrylate rubber, silicone rubber, composite modified graphite, meerschaum fibers, potassium titanate whiskers, carbon fibers, aluminum fibers, silicon carbide fibers, molybdenum fibers, talcum powder, zirconium silicide, aluminum carbide, barium sulfate, zinc stannate, octaphenyl silsesquioxane and zirconium boride; and the composite modified graphite is prepared through the following steps: adding phenolic resin, a silane coupling agent KH-550, natural graphite oxide, nano-silica, nanometer titanium dioxide, nano-alumina, ethyl orthosilicate and phenyltriethoxysilane to ethanol, uniformly mixing above added materials and ethanol, stirring the added materials and ethanol at normal temperature for 2-4 h, heating the obtained mixture to 65-75 DEG C, stirring the heated mixture for 20-50 min, evaporating the stirred mixture, drying the evaporated mixture, carrying out dry crushing, and filtering the crushed mixture through a 300-350 mesh sieve.

Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to a high-temperature-resistant heavy-duty automobile 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 material for the friction plate is low, and the thermal stability is poor when the friction generates high temperature. Some raw materials are easily oxidized when the high...
