Embodiment

[0026] Embodiment: the preparation method of basalt fiber friction material, comprises the following steps:

[0027] (1) Preparation of mixed fiber skeleton: take basalt fiber, aramid fiber, carbon fiber and potassium titanate fiber according to the weight ratio of 3:2:2:1, and take an appropriate amount of viscous material composed of nitrile modified phenolic resin and nitrile rubber powder. Put the agent into the high-speed mixer and stir for 5-7 minutes, and the speed of the high-speed mixer is 3300 rpm; after mixing evenly, send it into the mold cavity of the hot-press molding machine, and heat-press at a temperature of 160 degrees Celsius and a pressure of 35MPa In 200 seconds, a mixed fiber skeleton was prepared;

[0028] (2) Ingredients and mixing: According to the weight ratio of 1:1, take reinforcing fibers and fillers that are 1.2-2 times the weight of the mixed fiber skeleton, put them into a high-speed mixer, and add an appropriate amount of binder to stir for 5 m...

Abstract

The invention discloses a basalt fiber friction material which comprises a mixed fiber framework, binders, reinforced fibers and fillers. The mixed fiber framework and the reinforced fibers take basalt as a main raw material, high and low temperature resistance of the friction material can be enhanced, friction loss is reduced, and the temperature strain performance of the friction material is improved. No asbestos is added into the friction material, the cost is low, base materials are better in overall combination, metal wires are uniformly distributed, and the friction material is rapider and better in heat conduction and heat dissipation. Dimensional accuracy of a friction element made of the friction material is higher than that of an existing friction material. The problems of buddle swelling, layering, warping and the like in the production process of laminated products are completely avoided. The friction material has the advantages of high and low temperature resistance, wear resistance, low noise, stable friction brake torque, environmental protection and the like.

Description

technical field [0001] The invention relates to a friction material, in particular to a basalt fiber friction material and a preparation method thereof. Background technique [0002] Friction material is a functional accessory used in many sports machinery and equipment to play the role of transmission, braking, deceleration, steering, parking, etc. It can be said that since the beginning of mechanical movement, human beings have the requirement of braking, wooden blocks, Cowhide, rubber, etc. have all been used as braking materials. Before the 1970s and 1980s, asbestos friction materials had been widely used by humans as a traditional product. After that, it was rumored that asbestos would cause lung lesions and mesenchymal tumors and be related to the occurrence of lung cancer. In 1972, the International Oncology Symposium confirmed that asbestos fibers contained carcinogens. Since then, the asbestos-free and pollution-free friction products have gradually become the cons...
