Self-cleaning building coating

Abstract

The invention discloses a self-cleaning building coating. The self-cleaning building coating is prepared from the following components in parts by weight: 40 to 55 parts of water-soluble acrylic resin, 0.5 to 5 parts of a curing agent, 0.1 to 1 part of a surfactant, 3 to 5 parts of nano titanium dioxide, 15 to 18 parts of methyl methacrylate, 5 to 7 parts of butyl acrylate, 0.2 to 0.5 part of hydroxyethyl acrylate, 0.7 to 0.8 part of an initiator, 0.4 to 0.5 part of a pH regulator and 65 to 80 parts of deionized water. Compared with the prior art, the self-cleaning building coating disclosed by the invention is green, environment-friendly and good in self-cleaning performance.

Description

【Technical field】 [0001] The invention belongs to the technical field of building materials, and in particular relates to a self-cleaning architectural paint. 【Background technique】 [0002] As one of the most commonly used building materials, paint is a general term for a class of liquid or solid materials that can form a solid coating film with protection, decoration or special properties (such as insulation, anti-corrosion, signs, etc.) when applied to the surface of an object. Including paint, water-based paint, wood paint, powder coating, wood wax oil, essential for house decoration. [0003] At present, more and more exterior walls are also painted with paint to prevent the tiles from falling after being pasted for a long time, causing personal injury. However, most of the paints currently used in mass production on the market are solvent-based, containing a large amount of volatile organic solvents, which not only pollute the environment and waste resources, but also...
