Problems solved by technology

[0002] At present, in building decoration projects, coatings are generally used on building surfaces to prevent radon. However, due to the limitation of film-forming technology, the glass transition temperature of the emulsion is too high (greater than 30°C), and the particle size is relatively large (greater than μm). The coating film is not dense, easily penetrated by radon, and the anti-radon efficiency is not high, only about 60%, or the decorative effect is poor. The coating film is rough, poor in leveling, and easy to crack, so it cannot be applied to home decoration

Abstract

The invention provides nanometer anti-radon antibacterial latex paint, which comprises the following components in portion by weight: 95.0 to 115.0 portions of nanometer polyacrylate emulsion, 7.5 to9.5 portions of film-forming additives, 4.5 to 5.5 portions of sodium polycarboxylate serving as dispersant, 2.0 to 2.4 portions of anti-mildew anti-algae agent, 70.0 to 90.0 portions of nanometer titanium dioxide serving as antimicrobial agent, 125.0 to 145.0 portions of nanometer calcium carbonate serving as filler, 50.0 to 150.0 portions of nanometer barium metaborate serving as radioactive absorbent, 4.5 to 5.5 portions of associative thickener, 0.6 to 1.0 portions of pH regulator, 1.5 to 2.5 portions of leveling modifier, and 31.5 to 151.5 portions of water. The latex paint forms water-proof shielding film with bad air permeability in the coating process, has the advantages of high indoor anti-radon efficiency, good decorative effect, easy construction and the like, and can be used asanti-radon material for modern families, high-radioactivity buildings and underground buildings.

Description

technical field [0001] The invention relates to a kind of architectural paint, in particular to nano anti-radon antibacterial latex paint. Background technique [0002] At present, in building decoration projects, coatings are generally used on building surfaces to prevent radon. However, due to the limitation of film-forming technology, the glass transition temperature of the emulsion is too high (greater than 30°C), and the particle size is relatively large (greater than μm). The coating film is not dense, easily penetrated by radon, and the anti-radon efficiency is not high, only about 60%, or the decorative effect is poor, the coating film is rough, poor in leveling, easy to crack, and cannot be applied to home decoration. Contents of the invention [0003] The object of the present invention is to provide a kind of anti-radon antibacterial latex paint of nanometer, to overcome the above-mentioned deficiencies in the prior art. [0004] Nano anti-radon antibacterial l...
