Problems solved by technology

However, although the low-molecular-weight surfactant-type antistatic agent currently used is easy to migrate to the surface to achieve the purpose of antistatic, its main disadvantages are poor durability, no scrub resistance, and high dependence on environmental humidity, which reduces the heat-resistant temperature of the material. and surface properties, and its negative impact on the environment when detached from the polymer substrate

Abstract

The invention belongs to the technical field of high polymer materials, and particularly relates to a nano mesoporous material / surfactant type composite antistatic agent as well as a preparation method and applications thereof. According to the invention, a nano mesoporous material is adopted as a carrier, and traditional commercial surfactant type antistatic agent molecules are packaged in the nano mesoporous material, so that a novel long-acting composite antistatic agent is prepared, and applied to antistatic high polymer materials. The novel antistatic agent not only has excellent antistatic properties of traditional surfactant type antistatic agents, but also has a strong slow-release effect, so that the timeliness and permanence of an antistatic effect can be effectively improved. The novel antistatic agent is beneficial to solving various problems occurring in the industrial application processes of the traditional surfactant type antistatic agents; and due to the method, high polymer materials have efficient antistatic properties, and the mechanical and thermal properties and the like of a composite material are enhanced and improved because of a nano-effect.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a nano-mesoporous material / surfactant type composite antistatic agent and a preparation method and application thereof. Background technique [0002] General-purpose polymer materials are widely used because of their low price, excellent electrical insulation performance, chemical resistance and good processing performance. However, during its use, due to external environmental influences such as friction and external magnetic field induction, it is easy to accumulate static charges, resulting in many 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 generally limits the surface resistivity of materials to 10 12 ohm / sq or less. Adding antistatic agents to polymer substrates is the most commonly used effective method t...
