[0009] Patent CN1270189A provides a preparation method of nylon resin with high self-lubrication and high wear resistance. Although ultra-high molecular weight polyethylene resin is used as self-lubricating and wear-resistant agent, the patent does not use resistance High-temperature nylon is also reinforced by continuous fibers; patent CN101134844A provides a flame-retardant and wear-resistant semi-aromatic polyamide composition. Wear-resistant agent and self-lubricating agent are also different; Patent CN1607219A provides a kind of high self-lubricating, wear-resistant, reinforced nylon engineering plastic alloy and its manufacturing method, although its patent also used glass microspheres, potassium titanate whiskers, polytetrafluoroethylene Vinyl fluoride and ultra-high molecular weight polyethylene, but it is not reinforced with continuous fibers, and it is also used for the impregnation and cladding equipment of continuous long fiber reinforced thermoplastic materials to prepare composite materials

Description

technical field [0001] The invention belongs to the field of high-temperature-resistant nylon composite materials, and relates to a continuous long fiber reinforced high-temperature-resistant nylon composite material and a preparation method thereof. Background technique [0002] Engineering plastics generally have the characteristics of excellent self-lubrication, wear resistance, low friction and special anti-seizing properties, and can work normally even under poor lubrication conditions, so they are ideal wear-resistant materials. Nylon has good structural regularity and strong crystallinity. Compared with other engineering plastics, it has more prominent self-lubricating properties, less wear and friction factors, and is more suitable for wear-resistant materials. [0003] In recent years, with the advancement of science and technology and industrial development, the performance requirements of nylon are getting higher and higher. As a lightweight and high-strength wear...
