Title:
COMPOSITE ANTISTATIC AGENT AND PREPARATION METHOD THEREFOR, ANTISTATIC POLYOXYMETHYLENE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/109368
Kind Code:
A1
Abstract:
A composite antistatic agent. The preparation method therefor comprises: performing surface functionalization treatment on a metal oxide by using a coupling agent so as to obtain a modified metal oxide; performing melt mixing on polyethylene glycol, an alkaline earth metal compound and the modified metal oxide; and performing extrusion and granulation so as to obtain the composite antistatic agent. The metal oxide is ZnO, PbO, In2O2, SnO, V2O2, CuO or TiO2. The polyoxymethylene prepared by the composite antistatic agent has better antistatic performance and mechanical toughness.
