Abstract: A high wear-resistant nylon composite material for rollers of an airport freight vehicle and a preparation method thereof are disclosed. The composite material includes the following materials as the main components, 60-80 wt % of nylon 6 or nylon 66 or a mixture of nylon 6 and nylon 66, 5-13 wt % of glass beads, 6-14 wt % of glass fiber powder, 5-7 wt % of lubricating anti-wear agent. The composite material further includes the following materials as the auxiliary materials, 3-5 wt % of graft type toughening modifying agent, 0.3-1 wt % of antioxidant, 0.2-0.3 wt % of lubricating dispersant and 0.2-0.5 wt % of nucleating agent. The composite has characteristics such as high wear resistance, high heat resistance, relatively high toughness and skid resistance.

Abstract: The present utility model is a nylon conveyance roller used for the lifting platform loader of aircraft cargo transit wagon, wherein there is a tunnel going through the said roller for placing the axle. The tip and toe of the said roller are provided with plane structure, and the outer surface of the said roller is frosted texture. The material Nylon, designed for making the said conveyance roller, is suitable. It can increase the friction between the roller and the floor of container and container plate during cargo conveyance, making skidding conditions or noise during rotating friction unlikely. By using nylon as material, the said roller can boast good wear resistance, low noise, a slim likelihood of skidding condition, and environmental compliance.
