Abstract

The present invention proposes an environment-friendly and deodorizing water-based antique decorative paint and a preparation method thereof. The water-based antique decorative paint is made of porous sepiolite adsorbed on potassium permanganate, and then reduced by a reducing agent to obtain sea foam loaded with nano-α-MnO2 Stone powder, mixed with maleic anhydride graft copolymer and water to obtain functional fillers, and finally mixed with defoamer, alkali swelling thickener, dispersant, anti-sedimentation agent, polyurethane modified acrylic emulsion, amba toner And made. In the decorative paint provided by the present invention, the nanometer α-MnO2 of the functional filler can continuously and effectively decompose and remove various harmful gases such as benzene series pollutants volatilized in interior decoration materials, and the sepiolite carrier has super strong adsorption capacity, which can It can remove peculiar smell without producing pollution itself, which can reduce the indoor VOC content and significantly improve the indoor air environment.

Description

technical field [0001] The invention relates to the technical field of decorative coatings, in particular to an environment-friendly and odor-free water-based antique decorative paint and a preparation method thereof. Background technique [0002] It is very common for newly renovated houses to exceed the standard air quality, which is mainly caused by the release of a large amount of gaseous pollutants from decoration and furniture materials. The main gaseous pollutants in indoor air include formaldehyde, benzene series pollutants (such as benzene, toluene and xylene), ammonia, TVOC, etc. Among them, formaldehyde has a strong irritant and is one of the most serious pollutants in indoor air. Modern people spend more than 90% of their time indoors. Therefore, interior decoration can bring beautiful environment, and at the same time, because of the harmful gas discharged by decoration materials, people's living environment will be polluted. [0003] At present, there are man...
