Architectural water-resistant acrylate outer wall paint

Abstract

The invention relates to an architectural water-resistant acrylate outer wall paint which is prepared from the following raw materials in parts by weight: 100 parts of acrylic resin solution, 20-30 parts of nitrocellulose, 5-15 parts of butyl acetate, 10-30 parts of methyl ethyl ketone, 30-40 parts of maleic anhydride, 15-35 parts of n-butanol, 25-35 parts of ethylene glycol, 10-20 parts of tinting pigment, 20-30 parts of calcium carbonate, 15-25 parts of pentaerythritol, 20-40 parts of deionized water, 25-35 parts of mold preventive, 15-35 parts of cobalt naphthenate and 10-30 parts of acrylic acid. The product does not have any hard lump, and is in a uniform state while being stirred. The solid content is 50-60%, the surface drying time is 1-2 hours, and the solid drying time is 18-20 hours. The paint does not have the phenomenon of blistering or shedding after being immersed in water for 2-3 weeks, and does not have any abnormity after being immersed in alkaline water for 5-7 days. The scrubbing resistance of the coated film is 1500-2000 times; and the paint can be widely produced and continuously used instead of the existing materials.

Description

technical field [0001] The application belongs to the field of coatings, in particular to a water-resistant acrylic exterior wall coating for buildings. Background technique [0002] Paint, traditionally called paint in China. The so-called 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, oil, or emulsion, with or without adding pigments, fillers, adding Corresponding additives, viscous liquid prepared with organic solvent or maleic anhydride. The relatively authoritative book "Painting Technology" in the Chinese coatings industry defines it as follows: "Painting is a material that can be coated on the surface of an object by different construction techniques to form a firm adhesion, a certain strength, and a continuous coating. Solid film. The film formed in this way is commonly called a coating film, also known as a paint film or a coating." The ma...
