Embodiment 1

[0016] T700-12K carbon fiber is used as reinforcement material, nylon 66 is used as matrix material, carbon fiber reinforced nylon 66 pellets with 10% carbon fiber content are processed and manufactured by twin-screw extruder, and new high-performance carbon fiber composite material wheel lining is processed by injection molding process The outer lining has an outer diameter of 240mm, an inner diameter of 190mm, and a thickness of 60mm.

[0017] Fix the processed outer lining on the lower template of the hot pressing mold, fill the inner cavity of the outer lining with unvulcanized nitrile rubber, pressurize the template and its heating system on the 200-ton hot press and keep it for 30 minutes at a temperature of 150 ℃, and then the pressure is released to make a new wheel liner blank with an inner liner.

[0018] The wheel lining of the present invention is obtained by machining the wheel lining blank to precise dimensions by using a lathe.

[0019] The wear resistance of t...

Embodiment 2

[0021] According to the processing technology described in Example 1, the carbon fiber content is 25%, pressurized on a 200-ton hot press and maintained for 40 minutes at a temperature of 150°C, and then taken out by releasing the pressure to make an outer diameter of 180mm, an inner diameter of 130mm, and a thickness of 90mm new wheel liners.

[0022] On the basis of maintaining the original shock-absorbing characteristics, the new wheel lining has a life span of more than three times that of the original nitrile rubber wheel lining compared with pure nitrile rubber wheel lining.

Embodiment 3

[0024] According to the processing technology described in Example 1, the carbon fiber content is 35%, pressurized on a 200-ton hot press and kept for 50 minutes at a temperature of 155°C, and then the pressure was released to take it out to make an outer diameter of 280mm, an inner diameter of 200mm, and a thickness of 120mm new wheel liner.

[0025] On the basis of maintaining the original shock-absorbing characteristics, the new wheel lining has a life span of more than 5 times longer than that of the original natural rubber wheel lining.

Abstract

The present invention relates to a high-wearability carbon fibre reinforced nylon and rubber composite wheel liner and its production process. Said wheel liner is formed from two layers of structure, its internal layer is rubber vibration-absorptive layer and its external layer is carbon fibre reinforced nylon composite material wear-resisting layer. Said invention can be extensively used as wheel liner of supporting wheel of coal mine underground manned cable way and high mountain cableway.

Description

(1) Technical field [0001] The invention belongs to the technical field of overhead cableways and transport drag rollers, and is particularly suitable for use as a wheel lining of overhead cableway supporting rollers. (2) Technical background [0002] Aerial ropeways are widely used in many fields such as scenic sightseeing, material transportation, coal mine underground worker transportation, entertainment, etc. The supporting rollers of aerial ropeways are one of the key components to ensure the safe operation of ropeways. Because the supporting rollers are used in harsh industries and mines, some are used in the open air and are subjected to wind and rain all year round, and some are used in coal mine environments and are under dust environment all the year round, so the supporting rollers are required to have high wear resistance and high Excellent corrosion resistance, good shock absorption performance is also required, which is conducive to smooth operation and reduces...
