Problems solved by technology

However, various problems inevitably arise during the use of polymer antistatic agents. For example, the price of permanent polymer antistatic agents is relatively high, and the amount of filling required to form an internal electrostatic charge leakage network is also high. The difference in physical and chemical properties between polymer matrix materials will lead to the decline of thermal and mechanical properties of polymer materials

Abstract

The invention belongs to the technical field of polymer materials, in particular to a nanometer metal oxide / polymer composite antistatic agent and its preparation method and application. The composite antistatic agent of the present invention is a compound of a commercialized high molecular antistatic agent and nanometer metal oxide, and is applied to antistatic high molecular materials. The composite antistatic agent not only has the excellent antistatic performance of the parent antistatic agent, permanent electrostatic protection function and is less affected by the environmental humidity through the nano effect of the nano metal oxide and the interaction between the polymer antistatic agent Small and other characteristics, and can significantly reduce the amount of filling and production cost of the parent antistatic agent in the polymer material, thereby improving the thermodynamic properties of the polymer material. The excellent antibacterial, anti-aging and strong ultraviolet shielding capabilities of nano-metal oxides endow polymer materials with new potential excellent properties and broaden their application fields. The cost of the novel polymer composite antistatic agent is low, the preparation method is simple, and it is suitable for industrialized production.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a composite antistatic agent of nanometer metal oxide / polymer antistatic agent and its preparation method and application. Background technique [0002] Polymer materials are widely used because of their low price, excellent electrical insulation performance, chemical resistance and good processing performance. However, during the use of polymer materials, static charges are easily accumulated due to external environmental influences such as friction and external magnetic field induction, resulting in disasters such as dust collection on the device surface, film closure, electronic device breakdown, electric shock, and explosion. In order to eliminate electrostatic disasters, the industry usually reduces the surface resistivity (Surface resistivity, R s ) or volume resistivity (Volume resistivity, R v ). Low-molecular-weight surfactant-type antistatic a...
