Abstract

The invention discloses environment-friendly anti-static polyurethane anticorrosion paint and a preparation method thereof. The environment-friendly anti-static polyurethane anticorrosion paint comprises the following raw materials in parts by weight: 36-60 parts of aqueous polyurethane emulsion, 28-43 parts of aqueous acrylic resin, 4-13 parts of copper sulphide, 3-12 parts of montmorillonite, 2-9 parts of conductive mica powder, 2-10 parts of calcium carbonate, 2-5 parts of zinc oleate, 1-6 parts of PPG-n Laurate, 1-3 parts of sodium dodecyl sulfate, 1-2 parts of a levelling agent, 0.2-2 parts of an antifoaming agent, 12-25 parts of ethanol, and proper amount of deionized water. The prepared paint is large in surface resistance, shows good antistatic capability, and further, the conductive mica powder and copper sulphide raw materials are low in cost and easy to obtain and suitable for wide application. The prepared paint possesses good water proofness and acid resistance, displays excellent anticorrosion performance, and is long in practical service life and stable.

Description

technical field [0001] The invention belongs to the field of anticorrosion coatings, in particular to an environment-friendly antistatic polyurethane anticorrosion 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...
