Problems solved by technology

However, the pertinence of this scheme is not obvious, because when the idler is used in different environmental conditions (such as the southern region and the northern region), its performance requirements are different
In addition, when carrying out specific implementation according to this formula, the price is on the high side, and there are defects in promotion
[0004] Although the above technologies can solve certain problems, such as improving the impact resistance, wear resistance, corrosion resistance, and tear resistance of the idlers, these technologies still have not been designed specifically for the environment in which they are used; In addition, there are problems such as good performance but high price, or moderate price but difficult performance to meet the requirements of use.

Abstract

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.
