Problems solved by technology

[0003] But at present, the known various interior wall decorative paints, most of them lay particular stress on the requirements of decoration, and do not pay attention to the problem of indoor environmental pollution in the home. A kind of architectural coating, which mainly uses the chlorine partial emulsion in the formula to form a poor air permeability and water impermeable film during the coating process, thereby preventing radon gas from escaping and preventing water from oozing out, and has a certain anti-radon effect. However, it does not have the function of preventing benzene, xylene, formaldehyde, etc., and because the emulsion polymerization monomer used contains polyvinylidene chloride, the paint film is prone to yellowing, chalking and foaming

Abstract

A new type of composite water-based radon-proof latex paint for home interior wall decoration, the components and parts by weight are: water 280-320, hydroxyethyl cellulose 2-3, dispersant 3-5, defoamer 3 ~4, leveling agent 2.5~3.2, light calcium carbonate 100~130, titanium dioxide 170~200, bentonite 45~55, talcum powder 75~150, ethylene glycol 6~7, film-forming aid 3~4, PVDF-acrylate copolymer and vinyl acetate-acrylate copolymer emulsion 350~400, bactericide and antifungal agent 3~3.5. This coating can be used as a decorative coating on the wall, and can also form a barrier layer, which can absorb and prevent the precipitation and volatilization and diffusion of radon, benzene, xylene, formaldehyde, etc., which are harmful to the human body in the wall, and the effect can reach 80%. above.

Description

Technical field [0001] The invention relates to a chemical coating, in particular to a water-based radon-proof latex paint used for home interior wall decoration. Background technique [0002] With the improvement of people's living standards, people pay more and more attention to the problem of indoor environmental pollution in the home, and the main pollution factors that cause indoor pollution in the home are radon, benzene, xylene, formaldehyde, etc. Radon gas is a colorless, odorless radioactive gas, and benzene, xylene, formaldehyde, etc. are also chemical poisons harmful to the human body. They may exist in building materials such as bricks, gravel, concrete, prefabricated components, plywood, etc., and migrate from them by thermal motion and convection of atoms or molecules, from the interior of the substrate to the surface of the substrate and then to the air In the environment, when the concentration of these harmful gases accumulates and gradually increases, it w...
