Abstract

The invention relates to an HGM-C type high friction composite brake shoe and a preparation method thereof and belongs to the technical filed of materials. The preparation method of the HGM-C type high friction composite brake shoe comprises the following steps: firstly stripping and slicing rubber, then plastifying, adding auxiliary materials, mixing, rolling into slices, then weighing the slice, and carrying out shoe back treatment, hot-compression treatment and aftertreatment to obtain the HGM-C type high friction composite brake shoe product. After the HGM-C type high friction composite brake shoe product is vulcanized, friction and abrasion properties of the HGM-C type high friction composite brake shoe product meet the requirements of technical conditions of high friction coefficient composite brake shoes for railway freight cars (provisional) in shipment freight cars [2002], the phenomena of damascene, cracks, chip off-falling and the like can be effectively inhibited in a car loading using process, and damage to wheels is reduced; and the HGM-C type high friction composite brake shoe product has the characteristics of good impact property and good weather resistance.

Description

technical field [0001] The invention relates to a HGM-C high-friction synthetic brake shoe and a preparation method thereof, in particular to a friction material used in the HGM-C high-friction synthetic brake shoe and a preparation method thereof, and belongs to the field of material technology. Background technique [0002] At present, high-speed and heavy-duty will be the main direction of my country's railway development, and brake shoes are an indispensable component in the braking system of locomotives and vehicles. Due to the characteristics of railway transportation, the working conditions of the brake shoe are extremely complicated. It bears the effects of high temperature, static load and dynamic load. These factors affect the working performance of the friction parts of the wheel and the brake shoe. Phenomena such as metal inlays, cracks, and falling blocks occur, resulting in scratches, heat damage, cracks, and driving safety on the wheels, and the service life i...
