Abstract

The invention relates to a wear-resistant self-lubricating nylon composite material, and a preparation method and application thereof. The nylon composite material is composed of a nylon resin, a reinforcing fiber, a hydrophobic material, an anti-wear agent, a lubricant, an ultraviolet-resistant light absorber, an antioxidant and a compatilizer. The preparation method comprises the following steps: mixing the nylon resin, hydrophobic material, anti-wear agent, lubricant, ultraviolet-resistant light absorption agent, antioxidant and compatilizer, adding into a charging hopper, continuously metering and feeding into a double screw extruder, feeding the reinforcing fiber into the double screw extruder through a side feed metering screw, merging with the main materials, sending into a compounding region for blending, cooling, granulating and drying. The nylon composite material prepared by the method has the characteristics of high strength, low hydroscopic property, wear resistance, moisture resistance, weather resistance, excellent self-lubricating and the like, has the advantages of favorable dimensional stability and long service life, and can be widely used in the fields of lubricating bearings, shaft sleeves, mechanical gears, mine support rollers and the like.

Description

technical field [0001] The invention relates to a wear-resistant self-lubricating nylon composite material and its preparation method and application, in particular to a wear-resistant self-lubricating nylon composite material with high strength, low hygroscopicity, moisture resistance, weather resistance and excellent self-lubricating property and its preparation methods and applications. Background technique [0002] Bearings are important transmission parts of machinery, including two types: one is rolling bearings, and the other is sliding bearings. Rolling bearings are used for heavy-duty adjustment transmission, and sliding bearings are used for low-speed light-load transmission. Traditionally speaking, bearings are made of wear-resistant metal alloy materials. Metal alloy materials have the characteristics of high strength and large load carrying capacity. However, due to the large size of the parts manufactured by them, they are easy to corrode and wear, so regular ...
