NOVELTY - Coating comprises 50-60 pts. wt. diatomaceous earth, 5-10 pts. wt. silica gel, 4-5 pts. wt. calcium hydroxide powder, 1-2 pts. wt. graphene particles, 2-3 pts. wt. titanium dioxide powder, 10-15 pts. wt. hydroxyethyl cellulose powder, 0.5-1 pt. wt. bentonite, 5-8 pts. wt. nano-chitosan, 3-8 pts. wt. redispersible latex powder, 2-3 pts. wt. mesoporous silicon dioxide-coated silver nanoparticles, 0.5-1 pt. wt. defoamer and 40-50 pts. wt. deionized water. USE - The coating is used in interior wall for antibacterial and antiviral adsorption of carbon dioxide. ADVANTAGE - The coating solves that the effect of purifying the air of the existing interior wall coating needs to be further improved, where, in the case of high humidity, condensation occurs on the surface of the airtight wall, causing the problem of black mold and bacteria growth. The coating effectively absorbs carbon dioxide, reduces indoor carbon dioxide concentration, adsorbs toxic substances such as free formaldehyde, benzene, ammonia, radon, and total volatile organic compounds (TVOCs), is suitable for large-area coating of interior walls, improves the living environment, sterilizes and disinfects, and is not easy to produce black mold and bacteria.
