Problems solved by technology

[0003] At present, there are mainly paints, coatings, diatom mud, wallpaper products, etc. on the market for removing formaldehyde. These products may contain harmful substances, resulting in the secondary introduction of harmful substances. At the same time, there will be a lot of unpleasant smells during the construction process, and it is not convenient. Clean up, prone to "peeling" and "tears"

Abstract

The invention provides a preparation method of a plant formaldehyde-removing mud. Plant extracts are used as raw materials; and the plant extracts can be a tea extract, a wormwood extract, a pine needle extract, an aloe extract and the like. The extracts comprise tea polyphenol, cineole, platycladus orientalis ketone, flavonoid substances, vitamins, amino acids, mineral substances and the like, the substances have good effects of resisting radiation, refreshing mind and restoring consciousness and the like and can release faint scent, and the natural plant extracts are non-toxic and harmless.According to the preparation method, a titanium dioxide precursor is used as a raw material, and is mixed with quartz sand, so that prepared titanium dioxide and quartz sand are interlinked, nano titanium dioxide can efficiently adsorb formaldehyde, the main component of the quartz sand is silicon dioxide, which can effectively prevent fouling; the plant formaldehyde-removing mud also contains high-alumina cement and kaolin, and the high-alumina cement is high in strength and has high temperature resistance and corrosion resistance; and kaolin is high in chemical stability and has very high plasticity and adhesion.

Description

technical field [0001] The invention belongs to the technical field of chemical environmental protection, and in particular relates to a plant aldehyde-cleaning slime and a preparation method and application thereof. Background technique [0002] Most of the time in life is spent indoors, so the quality of the indoor environment directly affects human health. There are more than 300 kinds of pollutants produced by interior decoration materials, mainly formaldehyde, benzene compounds and ammonia compounds. These harmful substances seriously endanger people's physical and mental health. In recent years, the research and development of environmentally friendly and non-toxic interior decoration materials has become a hot topic of concern. [0003] At present, there are mainly paints, coatings, diatom mud, wallpaper products, etc. on the market for removing formaldehyde. These products may contain harmful substances, resulting in the secondary introduction of harmful substances....
