Abstract

The invention relates to a high-wear-resistant super-toughness environment-friendly flame-retardant nylon gear. Through the reasonable element proportioning, flame retardants are compounded; the flame retardant performance is better; through the cooperated effect of lithium ions and potassium ions of lithium chloride and gallium chloride in the reasonable mixture ratio, the toughness is enhanced; the effect of avoiding performance reduction due to damage to inside structures of polyamide can be ensured; SiO2 is added into the polyamide as an enhancing body; the material wear-resistant performance can be enhanced; partial energy can be absorbed when the material receives collision; the direct fracture of molecular chains of the polyamide material is prevented; the anti-impact performance, the stretching performance and the fracture performance of the material are improved.

Description

technical field [0001] The invention relates to a gear, in particular to a highly wear-resistant, super-tough, environment-friendly and flame-retardant nylon gear. Background technique [0002] Nylon has good comprehensive properties, including mechanical properties, heat resistance, wear resistance, chemical resistance and self-lubricating properties, and has a low coefficient of friction, certain flame retardancy, and is easy to process. Because nylon is non-toxic, Light weight, excellent mechanical strength, wear resistance and good corrosion resistance, so it is widely used to replace copper and other metals in the manufacture of bearings, gears, pump blades and other parts in machinery, chemical industry, instrumentation, automobile and other industries. Polyamide has high strength after melt spinning, it is mainly used as synthetic fiber and can be used as medical suture [0003] It is a true self-lubricating nylon, and a liquid lubrication system is formed during the...
