Problems solved by technology

However, the performance of the existing ceramic-based brake pads is not stable enough. Many brake pads tend to decline in friction performance and tend to lock or drag at high temperatures.
At the same time, due to the unreasonable combination of components, the metal mosaic phenomenon occurs
Sometimes there are even serious quality problems such as friction material expansion and friction surface cracks; at the same time, due to restrictions on the use of copper, traditional copper-containing friction materials cannot meet new environmental protection requirements

Description

Technical field: [0001] The invention relates to a copper-free and metal-free environment-friendly ceramic-based friction material and a preparation method thereof, belonging to the technical field of friction materials. Background technique: [0002] In today's world, with the advancement of science and technology, more new technologies are applied to the field of automobile manufacturing, which also makes the automobile develop towards high speed and high load; at the same time, people also put forward particularly high requirements for comfort. The improvement of braking technology requirements is not only reflected in ensuring safety. Friction material products should not only meet the requirements of braking, but also meet the requirements of low noise, long life, low dust, and non-aggressive duality. [0003] With the enhancement of environmental protection awareness in various countries, the intensity of environmental protection is getting stronger and stronger, ...
