Abstract

The invention discloses a conductive antistatic coating, a coiled material, and a preparation method of the coiled material. The coating comprises a component A and a component B according to a weight ratio of 10:2-5; the component A comprises, by mass, 40-65% of epoxy resin, 10-15% of a dilution agent, 1-5% of a flexibilizer, 0.5-1% of a wetting dispersant, 0.1-0.5% of an antifoaming agent, 0.1-0.5% of a leveling agent, 1-5% of short carbon fibers, 15-35% of a conductive filler, 1-5% of a color paste, and the balance of a mineral filler; and the component B comprises 91-98% of a curing agent, and the balance of a curing accelerator. The short carbon fibers and the conductive filler are added to the coating, so the conductivity of the coating is good; and a carbon fiber cloth, a carbon fiber felt and a carbon fiber surface felt are adopted as the conductive skeleton of the coiled material, so the resistance of the coiled material is reduced, the conductivity of the coiled material is guaranteed, and the mechanical performances of the coiled material are improved.

Description

technical field [0001] The invention relates to the technical field of polymer coatings and coils, in particular to a conductive antistatic coating, a coil and a preparation method thereof. Background technique [0002] With the continuous advancement of science and technology and the continuous improvement of the degree of automation, the requirements for anti-static are getting higher and higher. The weak charge and the charge caused by friction will hinder the automated production process, affect the accuracy of high-precision instruments and product processing quality, and seriously It may cause accidents such as fire and explosion. [0003] At present, most of the existing antistatic coatings use conductive powder and conductive fiber conductive materials as external conductive materials. [0004] The invention patent application document with the application publication number CN1594470A discloses a high-solid antistatic epoxy floor coating, which uses conductive powd...
