Abstract

The invention provides a wear-resistant and antistatic polyoxymethylene material and a preparation method thereof. The polyoxymethylene material is prepared from the following raw materials. In parts by weight, the raw material includes the following components: polyoxymethylene 100, polytetrafluoroethylene 5-20, antistatic agent 1-10; the polyoxymethylene material of the present invention is passed through The wear-resistant additive polytetrafluoroethylene is added to the polyoxymethylene system to form a POM / PTFE system, which makes the system have excellent wear resistance. The compatibility and dispersion of PTFE in the matrix are improved, and the antistatic performance of the system is greatly improved. The polyoxymethylene material of the present invention not only has excellent wear resistance, but also has good antistatic performance, and has wider applications than existing polyoxymethylene materials.

Description

Technical field [0001] The invention belongs to the field of polymer material engineering plastics and its molding processing, and specifically relates to a wear-resistant and antistatic polyoxymethylene material and a preparation method thereof. Background technique [0002] Polyoxymethylene (POM) is a kind of engineering plastic with excellent comprehensive performance. It is widely used in industries such as automobiles, electronic and electrical, household appliances, machinery and building materials. However, with the continuous expansion of application fields, new modified polyoxymethylene grades It must also match. In some specific applications, such as automobile fuel systems, underground transmission systems, etc., the electrostatic charge that may accumulate in polymer parts in use is very lethal. Therefore, these parts are required not only to have good friction and wear characteristics, but also to have certain antistatic properties. In the patent "New conductive po...
