Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a wear-resistant enhanced POM and a preparation method thereof. Background technique [0002] Polyoxymethylene, abbreviated as POM, is a thermoplastic crystalline polymer known as "super steel" or "sai steel", also known as polyoxymethylene. POM has the hardness, strength and rigidity similar to metal, and it has good self-lubrication, good fatigue resistance and elasticity in a wide range of temperature and humidity. In addition, it has good chemical resistance. character, but it has the disadvantage of not being resistant to ultraviolet radiation from the sun. [0003] At a lower cost than many other engineering plastics, POM is replacing some markets traditionally occupied by metals, such as replacing zinc, brass, aluminum and steel to make many parts. Since its inception, POM has been widely used in electrical and electronic, mechanical , instruments, ...
