Abstract

The invention discloses an on-rust anticorrosive paint for steel and iron and a preparation method thereof. Pure water, polyvinyl chloride resin, silicone rubber, acetone, vermiculite power, kaolin, white oil, glycerin, benzotriazole, barium petroleum sulfonate, vinyl acetate, butyl acrylate, acrylic acid and potassium peroxodisulfate are weighed and taken, and the raw materials are agitated, and then are ground, so as to prepare the on-rust anticorrosive paint for the steel and the iron. A paint film is uniform and bright in appearance, has surface drying time of 20min to 40min, actual drying time of 3h to 7h, flexibility of 140mm to 180mm and adhesive force of level 1-2, does not bubble or fall off when being immersed in water at 30 DEG C to 40 DEG C for 7d to 11d, and has the impact strength of 650N / cm to 850N / cm; the on-rust anticorrosive paint for the steel and the iron is used for protecting the surfaces of metal steel products, has the hardness of 2H-6H, and can be widely produced and used for continually replacing existing materials.

Description

technical field [0001] The invention relates to a coating for iron and steel surfaces, in particular to a rusty anticorrosion coating for iron and steel and a preparation method thereof. Background technique [0002] Antirust coatings are coatings that protect metal surfaces from chemical or electrochemical corrosion from the atmosphere, vermiculite powder, etc. Coating anti-rust coatings on the metal surface can effectively prevent the direct invasion of various corrosive substances in the atmosphere, so as to maximize the extension of the service life of the metal. It can be divided into two categories: physical and chemical antirust paint. The former relies on the proper coordination of pigments and paints to form a dense paint film to prevent the intrusion of corrosive substances, such as iron red, aluminum powder, graphite antirust paint, etc.; the latter relies on the chemical antirust effect of antirust pigments, such as red Dan, zinc yellow antirust paint, etc. Us...
