Abstract

The water soluble inorganic zinc paint consists of two components, component A and component B, in the weight ratio of 1 to 1.5-4. The component A is prepared through mixing alkali silicate, water soluble resin, nano colloid solution of inorganic oxide and silane as cross-liking agent under stirring for reaction to obtain sol; ageing the sol to obtain gel; adding pure water, inorganic pigment, alkali water solution and water soluble defoaming agent; and grinding. The component B is prepared with spherical zinc powder, chip metal powder, alkali-resisting inorganic pigment and stuffing, wetting carboxylate dispersant and through mixing. The paint has good early stage water resistance, high slipping resistance and high salt mist corrosion resistance, and the production process has no waste water, slag and waste gas produced and is environment friendly.

Description

technical field [0001] The invention relates to a water-based paint and a manufacturing method thereof, in particular to a water-based two-component inorganic zinc paint and a manufacturing method thereof. The paint is especially suitable for the protection of high-strength bolt connection surfaces, and can also be widely used in the anticorrosion of steel structures. Background technique [0002] Water-based inorganic zinc-rich coatings are one of the few excellent coatings that can protect steel structures and make their corrosion resistance life exceed 10 years. It achieves the purpose of anti-corrosion through electrochemical action, that is, anode action. Its coating film is very hard and wear-resistant, has excellent chemical corrosion resistance within a certain pH value range, and can withstand high temperatures up to 400 °C. It can be used either as a single long-lasting protective coat or as a primer for high-performance paint systems. Since the 1970s, it has been...
