Abstract

The invention provides a rubber based granular material and a preparation method thereof, and more specifically relates to the technical field of automobile components. The total mass of raw material components of the rubber based granular material is used as a reference for calculation, and the rubber based granular material comprises the following raw material components in percentages by mass: 7-12% of butyronitrile rubber, 2-5% of styrene butadiene rubber, 3-7% of carbon black, 1-4% of sulphur, 1-3% of a vulcanization accelerator, and 70-85% of a multielement heat-conducting composite powder. The rubber based granular material can replace brass fiber in a friction material in equal proportion, and friction performance and abrasiveness of the prepared friction material are nearly not changed; at the same time, compared with the brass fiber, the noise reduction performance of the rubber based granular material is better, comfort level of a pedal in a braking process is greatly improved, initial performance is excellent when the addition amount is small, and running-in period is shortened; the rubber based granular material has the advantages of cleaning, and environmental protection without pollution.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a rubber-based granular material and a preparation method thereof. Background technique [0002] In recent years, the global automobile industry has developed rapidly. As one of the key components in auto parts, brake pads not only determine the safe and comfortable driving of the car, but also one of the important factors affecting energy conservation and environmental protection in the automotive industry. [0003] The development of friction materials for automobile brake pads has a history of hundreds of years. In order to meet the needs of global development, at present, asbestos-type friction materials have been eliminated due to the strong carcinogenicity of asbestos, and replaced by semi-metallic, low-metal and non-metallic. Asbestos organic (NAO) friction material, and copper, as a good regulator in the above friction material formula, has good thermal properties, me...
