Abstract

The invention discloses a metal water-proof paint. The metal water-proof paint comprises the following components in parts by weight: 35-55 parts of acrylic acid, 15-20 parts of aluminum chloride, 20-22 parts of styrene-acrylic emulsion, 5-8 parts of weather-proof silicone adhesive, 6-10 parts of polyurethane, 3-5 parts of vinyl caproate, 2-3 parts of iso-octanol, 1-2 parts of nano silicon dioxide and 20-30 parts of water. The metal water-proof paint has the beneficial effects that the corrosion of water to the metal surface can be effectively protected, meanwhile, the adhesion of the paint is strong, the paint does not fall off even though the paint is soaked in water for a long time, the protection capacity of the metal against the water corrosion is improved, and in-plant experiments prove that the water corrosion resistance effect is 3-4 times that of similar products.

Description

technical field [0001] The invention relates to the field of metal protection, in particular to a metal waterproof coating and a preparation method thereof. Background technique [0002] Painted on the metal surface, a thin film is formed by the volatilization of solvent or water or the chemical reaction of the two components, which isolates the metal surface from water and thus plays a waterproof role. These viscous liquids painted are called metal waterproof coating. The waterproof film formed after the waterproof coating is cured has certain extensibility, elastic-plasticity, crack resistance, impermeability and weather resistance, and can play the role of waterproof, anti-seepage and protection. The waterproof coating has good temperature adaptability, easy operation, easy repair and maintenance. However, the previous metal waterproof coatings have higher requirements on the spraying process, and the waterproof effect cannot meet expectations. Contents of the inventi...
