Novel wear-resistant anti-static polyformaldehyde material and preparation method thereof

Abstract

The invention provides a novel wear-resistant anti-static polyformaldehyde material and a preparation method thereof. The polyformaldehyde material is prepared from the following raw materials in parts by weight: 100 parts of polyformaldehyde, 5-20 parts of polytetrafluoroethylene and 1-10 parts of antistatic agent. According to the novel polyformaldehyde material provided by the invention, since the wear-resistant additive polytetrafluoroethylene is added into a polyformaldehyde system to form a POM / PTFE (Polyformaldehyde / Polytetrafluoroethylene) system, so that the system has excellent wear-resistant performance. Meanwhile, polyether-modified silicone oil with a unique performance is added into the POM / PTFE system, so that the compatibility and the dispersibility of PTFE in a matrix are improved and the antistatic performance of the system is greatly improved. The novel polyformaldehyde material provided by the invention not only has excellent wear-resistant performance, but also has good antistatic performance. Compared with existing polyformaldehyde materials, the polyformaldehyde material provided by the invention has a wider scope of application.

Description

technical field [0001] The invention belongs to the field of polymer material engineering plastics and their molding processing, and in particular relates to a wear-resistant and antistatic polyoxymethylene material and a preparation method thereof. Background technique [0002] Polyoxymethylene (POM) is an engineering plastic with excellent comprehensive performance, which is widely used in industries such as automobiles, electronics, household appliances, machinery and building materials. However, with the continuous expansion of application fields, new POM modified grades must also match. In some specific applications, such as automotive fuel systems, underground transmission systems, etc., the electrostatic charge that may accumulate in polymer parts during use is very fatal. 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 Polyoxymethylene Material...

Problems solved by technology

However, because the compatibility between PTEF and POM is extremely low, and the melting temperature of the two is very different, the application of PTEF in the POM system is limited.
