Abstract

The invention discloses a preparation method of an antistatic coating, and belongs to the technical field of high polymer materials. The preparation method comprises the following steps: mixing and fermenting sisal fibers, a bacillus pasteurii bacterial solution, urea and water, dropwise adding an iron nitrate solution, stirring and mixing, filtering, freezing, ball-milling, sieving, drying and carbonizing the mixture, performing gradual heating, and carrying out high-temperature treatment to obtain the modified fibers. According to weight ratio, 40-60 parts of modified epoxy resin, 40-60 parts of a diluent, 10-20 parts of pretreated mica powder, 10-20 parts of modified fiber, 10-20 parts of modified additive, 5-8 parts of a curing agent, 5-8 parts of modified sepiolite, 20-30 parts of alkaline phenolic resin and 10-20 parts of modified diatomite are stirred and mixed to obtain the antistatic coating. The anti-static coating provided by the invention has excellent anti-static performance.

Description

technical field [0001] The invention discloses a preparation method of an antistatic coating, which belongs to the technical field of polymer materials. Background technique [0002] Non-metallic structural / functional materials represented by resin-based composite materials have the characteristics of light weight, designable performance, and easy mass production, and their application range is expanding day by day. The volume resistivity of resin-based composite materials is relatively high, generally greater than 109Ω·cm. When the surface is subjected to friction and impact by air flow, solid particles and liquids, it is easy to generate and accumulate static electricity. When the accumulation of static electricity reaches a certain level, it will cause electrostatic discharge, which will lead to the breakdown and scrapping of the components of the equipment, the failure of the control system, the reduction of the accuracy of the hit, and the danger of explosion of the wea...
