Abstract

The invention provides an anti-deviation friction disc made of an ultra-high molecular weight polyethylene material and a preparation method thereof. The ultra-high molecular weight polyethylene material used by the anti-deviation friction disc comprises the following compositions by weight portion: 50 to 150 portions of ultra-high molecular weight polyethylene, 2 to 6 portions of tissuemat E, 1 to 3 portions of graphite, 5 to 15 portions of glass hollow microbeads, 2.5 to 7.5 portions of a flame retardant, 0.3 to 1.9 portions of a coupling agent, 0.1 to 0.5 portions of a nucleating agent and 0.5 to 3.2 portions of an antioxidizer. The preparation method comprises the following steps of batching, mixing, heating, hydraulic pressing, cooling, demolding and forming. The material has high wearing resistance, good self-lubricity, super shock strength, good fire resistance, super inadhesion, age resistance and corrosion resistance, and is mainly applied to the manufacture of the friction aligning idler anti-deviation friction disc.

Description

technical field [0001] The invention relates to an ultra-high molecular weight polyethylene material anti-bias friction plate for friction self-aligning idlers and a preparation method thereof, belonging to the field of polymer processing applications. Background technique [0002] Rollers are widely used in open-air, dusty and highly corrosive harsh environments, such as mining industry, chemical industry, coking industry, steel industry, electric power industry, coal washing industry, grain processing industry, metallurgical industry, cement production industry, etc. The friction self-aligning idler roller can prevent the conveyor belt from being damaged and deviation, and it uses the friction resistance and the deviation adjustment mechanism of the friction wheel radian to prevent and correct the deviation of the conveyor belt. The anti-deflection friction disc of the steel friction self-aligning roller has high production cost, heavy weight, high energy consumption, no c...
