Summary: | The invention relates to the technical field of nylon materials for railway fastener systems, in particular to an anti-fatigue low-temperature-resistant nylon composite material and a preparation method and application thereof.The nylon composite material is prepared from, by weight, 30-60 parts of nylon 66, 20-40 parts of core-shell particles, 20-35 parts of glass fibers, 5-20 parts of a nylon toughening agent, 0.2-1.0 part of a nylon dispersing agent and 1-2 parts of a nylon compatilizer. 2-5 parts of a nylon heat stabilizer and 0.2-0.8 part of an antioxidant. The nylon composite material has high fatigue resistance and low temperature resistance, and can be applied to an environment of-50 DEG C; in addition, when the nylon composite material is applied to the baffle seat, the baffle seat is high in impact resistance and fatigue resistance after being boiled and humidified.
