Abstract

The invention discloses environment-friendly antistatic anti-corrosion paint and a preparation method thereof. The environment-friendly antistatic anti-corrosion paint is prepared from, by weight, 40-65 parts of waterborne polyurethane emulsion, 30-45 parts of waterborne acrylic resin, 5-15 parts of copper sulphide, 5-15 parts of montmorillonite, 3-12 parts of conductive mica powder, 10-20 parts of potassium titanate whiskers, 10-20 parts of zinc oxide whiskers, 3-12 parts of calcium carbonate, 3-8 parts of zinc oleate, 3-8 parts of poly[oxy(methyl-1,2-ethanediyl)], 3-6 parts of lauryl sodium sulfate, 1-2 parts of flatting agents, 0.3-2 parts of defoaming agents, 10-25 parts of ethyl alcohol and 80-100 parts of deionized water. The surface resistance of the prepared paint is large, and good anti-static capacity is displayed. Besides, the conductive mica powder and the copper sulphide are low in cost of raw materials, easy to obtain and suitable for being widely used. The prepared paint has good water resistance and acid resistance, shows excellent corrosion resistance, and is long in actual service life and stable.

Description

technical field [0001] The invention belongs to the field of anti-corrosion coatings, in particular to an environment-friendly anti-static anti-corrosion coating and a preparation method thereof. Background technique [0002] Among the many protective measures, painting is one of the most convenient, quick and effective protective measures. Coating is to apply paint on the surface of equipment products, which can play an insulating role to reduce the corrosion of equipment products by the external environment, prolong the service life of equipment, and reduce the cost of use. As people's requirements for the living environment are getting higher and higher, more and more attention is paid to environmental protection issues. However, most anti-corrosion coatings currently on the market contain volatile organic solvents, some of which are toxic or even carcinogenic, seriously affecting people's health; in addition, with the popularization of electronic products, the electroma...
