Problems solved by technology

[0003] Existing antistatic methods for plastic products include: adding surfactants, the surface resistance of the product is set above 109 ohms, but the surface resistance of the product is easily affected by environmental factors and fluctuates greatly; if adding a polymer antistatic agent, but There is a disadvantage of poor compatibility between polymer antistatic agents and materials; if conductive fillers such as carbon black are added inside, although the conductivity of the product is good, the product has color shift, which easily affects the transparency of the product; if the surface is sputtered with conductive materials, Its cost is high, the efficiency is low, and it is not easy to produce on a large scale; there are also literatures that can be coated with high molecular polymers, but the adhesion fastness of this method is not good
Although metal oxides as conductive agents have anti-static effects, they have poor placement stability, and the film after direct coating has uneven appearance, and there are phenomena such as streaks and blooming.

Description

technical field [0001] The invention relates to an antistatic composition and an antistatic film containing the composition. Background technique [0002] In industrial production and daily life, static electricity is everywhere, such as dust in industrial production, electrical products in use, electronic display screens, and so on. The existence of static electricity not only affects the quality of industrial products, but also endangers human health. Therefore, in these occasions, it is hoped to avoid the generation of static electricity to prevent harm to production and humans. [0003] Existing antistatic methods for plastic products include: adding surfactants, the surface resistance of the product is set above 109 ohms, but the surface resistance of the product is easily affected by environmental factors and fluctuates greatly; if adding a polymer antistatic agent, but There is a disadvantage of poor compatibility between polymer antistatic agents and materials; if ...
