Abstract

The invention discloses a diatom coating capable of degrading formaldehyde, belongs to the technical field of home decoration coatings and aims to solve the technical problem that existing diatom coatings are low in diatomite content and cannot truly adsorb and decompose formaldehyde effectively. The diatom coating is composed of a component A and a component B which are packaged independently, the component A is composed of water, hydroxyethyl cellulose, glycol, ND-1096 wetting agent, RT8040 dispersant, defoamer, LXE bactericide, titanium dioxide, light calcium, heavy calcium, talcum powder,nano titanium dioxide, nano zinc oxide, tourmaline powder, Changbai diatomite, kaolin and 5-20 parts of yellow clay, and the component B is composed of 25K2 hydroxyethyl cellulose, RF-86 multifunctional auxiliary, NXZ defoamer, vanadium doped modified titanium dioxide photocatalyst, nano zinc oxide, tourmaline powder, 1SF-18 styrene-acrylic emulsion, RT-1035 thickener, Changbai diatomite and water. The diatom coating is used for wall decoration.

Description

technical field [0001] The invention belongs to the technical field of home decoration coatings, in particular to a formaldehyde-degradable diatom coating. Background technique [0002] After "soot pollution" and "photochemical smog pollution", human beings are experiencing the third generation of pollution - "indoor pollution". The main source of indoor pollution is the building itself and interior decoration materials, and formaldehyde is the main pollutant released into the air by building materials and decoration materials, and the release time of formaldehyde is as long as 3 to 15 years. The national standard stipulates that the formaldehyde content in indoor air should be lower than 0.08mg / m 3 . In 2005, CCTV-2 conducted the first survey on the indoor environmental pollution of urban household decoration in cities nationwide. The results found that among the 566 households in the 22 cities surveyed, the average formaldehyde content of 71% of the residences exceeded t...
