The invention belongs to the field of high-molecular composite materials, and provides a high-performance multi-component compound modified nylon 6 composite material for a conventional carrier roller. The composite material consists of 100 parts of mixed nylon 6, 10-40 parts of alkali-free glass fiber, 5-30 parts of talcum powder, 0.01-1 part of nano silicon dioxide, 1-5 parts of solid lubricant, 0.01-3 parts of wear-resistant agent, 0.05-1 part of anti-aging agent, 0.2-1 part of dispersing agent and 0.01-0.5 part of silane coupling agent. After being uniformly mixed, the material system is extruded by a twin-screw extruder and granulated to obtain a high-performance composite material. By adopting the composite material provided by the invention, the prepared carrier roller has the characteristics of high strength, abrasion resistance, high-temperature resistance, light weight, low noise, long service life, appropriate price, convenience in maintenance and the like, and can be widely applied to the places such as mines except coal mines, wharfs, grain depots, cement plants, power plants, chemical plants, salt fields and the like.
