Problems solved by technology

These solvents will be volatilized during the coating construction process, causing waste of resources, environmental pollution, endangering the health of construction and users, and causing fire hazards
The base polymer emulsion used in one-component water-based anti-corrosion coatings is mostly thermoplastic, and the properties of coating film hardness, medium resistance, and pollution resistance cannot reach the level of solvent-based industrial coatings. Therefore, in recent years, people have begun to devote themselves to two-component water-based coatings. Research on Anti-corrosion Coatings

Description

technical field [0001] The invention belongs to an anti-corrosion paint for electrical network fittings, in particular to an anti-corrosion coating for electrical network fittings coated with a two-component water-based epoxy anti-corrosion coating and a method for making the anti-corrosion coating. Background technique [0002] Most of the traditional anti-corrosion primers for power grid fittings are solvent-based coatings, in which the content of organic solvents generally reaches 20% to 50% of the finished coating. When in use, 5% to 20% solvent is often added to dilute it for the convenience of construction. These solvents will be volatilized during the coating construction process, causing waste of resources, environmental pollution, endangering the health of construction and users, and generating fire hazards. The base polymer emulsion used in one-component water-based anti-corrosion coatings is mostly thermoplastic, and the properties of coating film hardness, mediu...
