Special-effect heath indoor wall aqueous paint composition and preparation method thereof

Abstract

The invention relates to a special-effect health indoor wall aqueous paint composition and a preparation method thereof, and belongs to the field of aqueous paint compositions for construction decoration. The paint composition is composed of the following raw materials in parts by weight: 20 to 30 parts of water, 0.2 to 0.5 part of thickening agent, 0.05 to 0.2 part of pH adjuster, 0.1 to 0.3 part of antifoaming agent, 0.1 to 0.4 part of wetting agent, 0.2 to 0.7 part of dispersant, 10 to 25 parts of nano titanium dioxide, 1 to 10 parts of nano diatom ooze, 2 to 10 parts of embedded anionic nano silicon dioxide, 20 to 40 parts of filling material, 9 to 18 parts of emulsion, 0.2 to 0.7 part of anti-freezing agent, 0.1 to 0.5 part of film-forming auxiliary agent, and 0.2 to 0.4 part of bactericidal mildew inhibitor. The paint composition can absorb the harmful components in air, is healthy and environment-friendly, and also has the advantages of excellent color retention, scrubbing resistance, water and alkali resistance, and proper softness of paint film.

Description

Technical field

[0001] The invention relates to an indoor wall water-based paint and a preparation method thereof, in particular to a special-effect healthy indoor wall water-based paint composition and a preparation method thereof, and belongs to the field of architectural decoration water-based paint compositions. Background technique

[0002] With the popularization of the Internet and indoor fitness equipment, people’s production and lifestyle are more modernized. More work and recreational sports activities can be carried out indoors. Shopping does not have to go to the streets every day. The suitable indoor microclimate prevents people from having to go outdoors frequently. Activities, in this way, people spend most of their active time indoors. According to survey statistics, people spend more than 80% of their time indoors on average every day, and some even up to 93%. Therefore, the relationship between indoor air quality and human health is closer, and people pay more ...

[0040] A special effect healthy indoor wall water-based paint composition, which is prepared from the following raw materials according to the following mass ratio through the following steps:

[0041] Under magnetic stirring, first mix 17 parts of polyethylene glycol octyl phenyl ether (Triton X-100) and 8 parts of n-octanol in a dispersing vessel, then add 60 parts of cyclohexane and stir for 35 minutes. Drop 1.5 parts of ammonia solution with a concentration of 24.5% by mass, then add 22 parts of negative ion powder and 36 parts of ethyl orthosilicate, then ultrasonically shake until the mixed solution is uniformly emulsion-like, and then drop 150 parts of water, through molecular diffusion and penetration , Followed by a hydrolysis condensation reaction, so that the tetraethyl orthosilicate undergoes a hydrolysis reaction, a layer of nano silica is deposited on the surface of the powder particles of the negative ion powder, and then the precipitate is separated by centrifugati...
