Problems solved by technology

Even if some diatom mud is added with decomposition materials such as photocatalysts, because photocatalyst nanomaterials tend to agglomerate and form agglomerates, it is not easy to disperse evenly, so direct addition will reduce the utilization efficiency of nanomaterials, increase the cost of products, and reduce the cost of products. Purification function

Abstract

The invention belongs to the field of diatom ooze paints, and discloses an anion-adsorption/decomposition composite diatom ooze and a preparation method thereof. The preparation method comprises the following steps: preparing a composite solution from 5-15 wt% of deionized water, 1-5 wt% of adhesive, 1-8 wt% of anion powder and 0.1-1.5 wt% of photocatalyst, and mixing the composite solution with 20-35 wt% of deionized water, 0.8-3 wt% of antifreezing agent, 0.5-1.0 wt% of thickener, 0.5-3 wt% of bentonite, 3-10 wt% of titanium white, 5-20 wt% of ash calcium, 20-40 wt% of diatomite and 0.1-1 wt% of retarder to prepare the diatom ooze. According to the method, the anion powder, photocatalyst and other materials can be dispersed more uniformly, thereby enhancing the utilization efficiency. The obtained product continuously releases hydroxy anions, thereby eliminating indoor peculiar smell and various harmful gases, and enhancing the indoor air quality. The diatom ooze can intelligently regulate the indoor air humidity. The diatom ooze is composed of pure natural inorganic materials, is free of any harmful substance or harmful additive, and thus, is a pure green environment-friendly product.

Description

technical field [0001] The invention belongs to the field of diatom mud coatings, in particular to a negative ion adsorption and decomposition composite diatom mud and a preparation method thereof. Background technique [0002] As people have higher and higher requirements for interior decoration, diatom mud is more and more popular as an environmentally friendly interior decoration wall material. The main component of diatom mud is diatomaceous earth. After compounding with fillers, additives and binders, it has extremely high porosity, so that diatom mud can absorb indoor air pollutants such as formaldehyde and benzene, and has a great effect on air purification. Certain effect. But this is only a simple physical adsorption, and there is a disadvantage that the purification effect will decrease after the adsorption is saturated. Even if some diatom mud is added with decomposition materials such as photocatalysts, because photocatalyst nanomaterials tend to agglomerate an...
