Problems solved by technology

Therefore, due to the molding method, molding conditions, shape and size of the product, various problems inevitably occur during the processing of the antistatic composite material, such as excessive filling due to local uneven dispersion or destruction of the fine network. The amount of use increases the production cost; and, the difference in physical and chemical properties between it and the polymer matrix material will lead to a decrease in the thermal and mechanical properties of the polymer material

Abstract

The present invention belongs to the technical field of polymer materials, and particularly relates to a nucleating agent / polymer composite antistatic agent, a preparation method and applications thereof. According to the present invention, the composite antistatic agent is the complex of the commercialized polymer antistatic agent and the nucleating agent, and is used for the antistatic polymer materials; the nucleating agent is added to the component of the composite antistatic agent so as to change the crystallization behavior of the polymer materials, wherein the crystallization rate and the crystal density are significantly increased and the grain particle size becomes smaller, such that the amorphous region becomes small, and the filling amount of the antistatic agent in the polymer material can be significantly reduced so as to reduce the production cost; with the composite antistatic agent, the permanent antistatic property is provided for the polymer material while the mechanical property and the processing property of the polymer material are enhanced; and the cost of the novel polymer composite antistatic agent is low, the preparation method is simple, and the method is 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 a nucleating agent and a polymer antistatic agent, a preparation method and application thereof. Background technique [0002] Polymer materials have been widely used in the fields of national defense and national economy because of their low price, excellent electrical insulation performance, chemical resistance and good processing performance. Generally, polymer materials have high surface resistivity ( R S ) or volume resistivity ( R V ). Therefore, during its use, it is easy to accumulate static charges due to external environmental influences such as friction and external magnetic field induction, resulting in disasters such as dust suction on the device surface, film closure, electronic device breakdown, electric shock, and explosion. In order to eliminate static electricity disasters, the industry usually improves ...
