Problems solved by technology

[0002] The traditional metal antirust paint uses organic solvents as the dispersion medium, and is mainly composed of styrene-acrylic emulsion and other additives. When in use, it is directly painted on the base surface to form a dense paint film, which isolates water vapor from contacting the metal surface, thereby preventing rust. However, the traditional metal anti-rust paint has a big smell, serious environmental pollution, poor anti-aging performance, short service life, outdoor rainy season and other climates seriously affect the effect of the coating film, resulting in poor sealing and sealing properties of the coating film, water resistance, salt resistance Fog resistance, salt water resistance (3% sodium chloride solution), acid resistance, etc. are poor, and the service life is not long, and can only last for about 1 year

Abstract

The invention discloses water-based metal antirust paint as well as a preparation method and a construction method thereof. The water-based metal antirust paint is composed of the following raw materials: an acrylic copolymer pure acrylic emulsion, a dispersing agent, a wetting agent, a defoaming agent, iron oxide powder, a coalescing agent, a preservative, mica powder, barium sulfate, zinc phosphate, heavy calcium carbonate powder, an anti-flash-rust agent, a thickening agent, a pH regulator and water. Water is used as a dispersion medium, and the raw material formula is prepared by utilizingmultiple antirust mechanisms such as physics and chemistry, so that the antirust paint has the characteristics of no toxicity, no odor, no pollution, no three wastes, no combustion and no explosion,and is environment-friendly and safe; the water-based metal antirust paint provided by the invention can be directly used, is simple, convenient and rapid, and a paint film formed after construction has excellent properties such as salt spray resistance, saline water resistance, fresh water resistance, gasoline resistance, ultraviolet light resistance, aging resistance, high temperature resistance, low temperature resistance, damp heat resistance, temperature change resistance and the like; the performance effect of a paint film formed after construction can be kept unchanged for at least three years, and the service life is long.
