Abstract

The invention belongs to the technical field of polymer materials, particularly relates to a composite antistatic agent of a nano-metal oxide/polymer antistatic agent, as well as a preparation method and application of the composite antistatic agent. The composite antistatic agent is a compound of commercialized polymer antistatic agent and nano-metal oxide, and is applied to the antistatic polymer materials. The composite antistatic agent not only has excellent antistatic performance, permanent static protection function, less environmental humidity influence and other characteristics of a mother antistatic agent, but also can significantly reduce the filling usage amount and production cost of the mother antistatic agent in the polymer materials through the nanometer effect of nano-metal oxide and the interaction with polymer antistatic agent molecules, so as to improve the thermodynamic properties of polymer materials. The excellent antibacterial and anti-aging properties and strong ultraviolet shielding ability of nano-metal oxide give the polymer materials new potential excellent properties and broaden the application field of the polymer materials. The novel polymer composite antistatic agent is low in cost, simple in preparation method, and suitable for industrial 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...
