Problems solved by technology

However, the nano-precious metal powder of this kind of diatom mud product is difficult to disperse in the product, and it is easy to agglomerate for the second time, so it cannot fully exert the effect of decomposing formaldehyde
[0004] The existing diatom mud coating adopts the gradual addition of nano-metal powder and nano-metal oxide powder, which is prone to agglomeration effect and cannot effectively reduce the content of formaldehyde in the air.

Abstract

The invention relates to a nano composite diatom ooze coating including a solvent and the following components with the total mass of 100%: 0.5-1.8% of cellulose, 5-18% of tourmaline, 5-15% of titanium dioxide, 4-18% of kaolin, 5-12% of a sepiolite powder, 35-55% of diatomite, 5-12% of a nano noble metal loaded type catalyst, 1-6% of nano activated carbon, 0.5-0.8% of a levelling agent, 1.5-5% of a thickener, 7-16% of a re-dispersible latex powder, and 0-5% of a pigment. The solvent is preferably water, and the amount of the water is 20-30%, preferably 25%, of the total mass of all the components. Nano noble metal particles are loaded on a carrier firstly and then mixed with other powders, so as to prevent an agglomeration effect of the nano noble metal particles. The prepared nano composite diatom ooze coating has extremely strong adsorption and ion exchange, can adsorb formaldehyde in air, and decomposes formaldehyde and other harmful gases under the action of the catalyst.

Description

technical field [0001] The invention relates to a coating, in particular to a nano-composite diatom mud coating and a preparation method thereof. Background technique [0002] In recent years, the wide application of coatings has attracted more and more researchers. With the improvement of people's living standards, environmental protection, low carbon, energy saving, etc. have become the trend of modern home decoration. [0003] Diatom mud has a unique molecular sieve and adsorption function, which can effectively absorb free formaldehyde, benzene, ammonia and other harmful substances in the air. By releasing water and negative oxygen ions, it can keep the indoor air fresh for a long time. However, it is difficult to disperse the nano-precious metal powder of this type of diatom mud product in the product, and it is easy to agglomerate for the second time, so it cannot fully exert the effect of decomposing formaldehyde. [0004] The existing diatom mud coating adopts the ...
