High-antistatic modified polymer insulating material and preparation method thereof

Abstract

The invention discloses a high-antistatic modified polymer insulating material, which comprises a protective insulating layer and an antistatic insulating layer, wherein the protective insulating layer and the antistatic insulating layer are formed by co-extrusion and have an insulating effect; and the protective insulating layer and the antistatic insulating layer are of a double-layer compositestructure. The static electricity is prevented from gathering on the surface layer of the material while the insulation effect is achieved; in the preparation method of a composite antistatic agent, modified attapulgite, nano conductive particles and graphene are used as main body framework materials; a mesh structure is formed, part of electrons can be timely transferred under conditions that the antistatic effect is not influenced; the migration speed of an antistatic agent in the material is reduced; the attapulgite, the nano conductive particles and the graphene material are used for adsorbing a large amount of the antistatic agent, and the migration speed of the antistatic agent in the material can also be reduced through the hydrogen-bond interaction and the adsorption capacity of the attapulgite, so that the effective action time of the antistatic agent is prolonged.

[0002] Insulating materials are widely used in many fields. Insulating materials are often used as protective materials to play various functions such as insulation and anti-corrosion. Due to the poor conductivity of insulating materials, it is easy to accumulate charges on the surface. In some occasions It will reduce the safety of use. In the prior art, a layer of electrostatic agent is often coated on the surface of the material or mixed with an electrostatic agent in the processed polymer material to endow the surface lubricity of the polymer material, inhibit and reduce the However, the electrostatic agent coated on the surface of the material will easily fall off after long-term use, resulting in a decrease in antistatic ability. Although the antistatic effect can be achieved by directly mixing the electrostatic agent in the polymer material, due to different The antistatic mechanism of antistatic agents is different, and their antistatic effect will be affected when they are used in different environments, and because the antistatic agent migrates faster in the product, the action time of the antistatic agent is limited, and Due to the compatibility of antistatic agents in polymer materials, it will affect the antistatic properties of materials
