Abstract

The invention belongs to the technical field of coatings, and particularly relates to a water-based rust conversion industrial coating and a preparation method thereof. The industrial coating is prepared from the following raw materials in parts by weight: 60-80 parts of water, 1-2 parts of diethylene glycol monobutyl ether, 15-20 parts of tannic acid, 2-5 parts of phosphoric acid, 2-5 parts of citric acid, 1-2 parts of alpha-allylalkylphenolethoxylates (10) ammonium sulfate, 150-250 parts of vinyl chloride-vinylidene chloride copolymer emulsion, 0.3-0.5 part of wetting agent, 0.3-0.5 part ofpolysiloxane defoamer, 0.5-0.8 part of water-based polyurethane thickener and 2-5 part of phosphate. The water-based rust conversion industrial paint prepared by the method has the advantages of highpaint film hardness, high surface drying speed, favorable rust resistance and the like.

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a water-based rust conversion industrial coating and a preparation method thereof. Background technique [0002] Paint, also known as paint, is coated on the surface of the object to be protected or decorated, and can form a continuous film firmly attached to the object to be coated, usually based on resin, or oil, or emulsion, with or without adding Viscous liquid prepared from pigments, fillers, adding corresponding additives, and organic solvents or water. [0003] When steel is exposed to the air, it is bound to be corroded by oxygen, moisture and other corrosive media and transformed into rust. The phenomenon of rust and corrosion of iron and steel pervades social life and production activities, bringing various injuries and economic losses to people. Therefore, anti-corrosion coatings are usually used as protective layers for iron and steel. Traditional anti-...
