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 large (greater than 1 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 present invention relates to a radon-proof wall surface paint, belonging to a building paint. It mainly utilizes the poor-permeability water-tight film formed in the course of coating the wall surface paint made up by using self-crosslinked styrene-acrylic acid copolymer emulsion, titanium pigment and calcium carbonate, etc. according to its formula to prevent the radon gas from evolving outward, so that it has the advantages of high indoor radon-resisting efficiency, good decorative effect.

Description

technical field [0001] The invention relates to an architectural coating, in particular to a radon-proof wall finish. 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 large (greater than 1 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 purpose of the present invention is to overcome the deficiencies of the above-mentioned prior art and provide a radon-proof wall finish that can be used for home decoration. [0004] The present invention is achieved through the following s...
