Next, diatomaceous earth is a fossil of diatom, a single-celled vegetable franc, and is a super-porous material with numerous large and small pores of various shapes.

It is known to be a light material with a structure of ultrafine space of more than 5,000 times that of charcoal. Because of this, diatomaceous earth has strong adsorption power and absorbs about half of its volume of water.

In the present invention, when the coating agent is coated on the zeolite, the antimicrobial and deodorizing power of the zeolite is added together with the nano-powder and the titanium nano-powder to decompose the odor and add the sterilizing power.

If the diatomaceous earth is mixed below the threshold value, the efficiency is lowered. If the threshold value is exceeded, the viscosity of the subject becomes higher and the work becomes difficult, and the ratio of the nano powder and the titanium nano powder is reduced.

Next, the silver nanopowder is excellent in antibacterial, sterilizing and deodorizing effects, and the titanium nanopowder is excellent in the decomposition and removal of harmful substances such as volatile organic compounds and formaldehyde. In the present invention, it is included for antibacterial, , And the antibacterial deodorizing effect is insufficient when it is mixed below the threshold value, and when it exceeds the threshold value, it is difficult to expect the price increase and the increased antibacterial, sterilization and deodorizing effect further.

Next, the water is intended to water the epoxy resin emulsified by the emulsifier.

Next, the antifoaming agent is for suppressing bubble generation, the leveling agent is for smoothly coating the coating agent, and the adhesion promoter is included for improving the adhesion of the coating agent to the zeolite.
