AI Technical Summary

Problems solved by technology

[0003] Most of the existing diatom mud decoration materials on the market have a single composition, and the effect of aldehyde elimination and sterilization is not ideal, and there is also a problem of weather resistance
For example, the diatom mud wall will continue to release formaldehyde, which greatly affects human health, and it is easy to fade, yellow, mold, and fall off after being exposed to moisture, and there are problems of easy aging and flammable safety hazards

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically, the invention relates to a nano-particle composite antibacterial and mildew-proof diatom mud. Background technique [0002] Diatom mud is a natural and environmentally friendly material that can be used to replace wallpaper and latex paint. It is suitable for wall decoration in villas, apartments, hotels, homes, hospitals, etc. Diatom mud is a dry powder wall decoration coating material prepared with diatomite as the main material. Diatomaceous earth is a single-celled aquatic plankton that lived millions of years ago, that is to say, the sediment of diatoms. After the death of diatoms, it will deposit on the bottom of the water. After hundreds of millions of years of accumulation and geological Change into diatomaceous earth. Diatomite is a natural substance deposited by diatoms, an aquatic plankton that lived millions of years ago. The main component is opal, which is ...
