Diatomite coating with formaldehyde adsorbing and decomposing effects

Abstract

The invention provides a diatomite coating with formaldehyde adsorbing and decomposing effects. The diatomite coating is formed by compounding raw materials comprising a diatomite dispersion liquid loaded with a material capable of decomposing formaldehyde, a 5040 dispersant, 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, a Kh-550 type silane coupling agent, a polyacrylate thickener, 2-amino-2-methyl-1-propanol, kaolin, mica powder, titanium dioxide powder, octyl phenol polyoxyethylene ether, ethylene glycol, a 705 EVA emulsion, an AGITAN-208 defoaming agent, isothiazolinone, water and the like, wherein the diatomite dispersion liquid loaded with the material capable of decomposing formaldehyde is formed by compounding a Cu / Al2O3 catalyst, anatase-type nanometer titanium dioxide, nanometer tungsten trioxide, diatomite, a 5040-type dispersant, a 405 wetting agent, an AGITAN-208 type defoaming agent, a 400 polyethylene glycol, 2-amino-2-methyl-1-propanol, a Kh-570 type silane coupling agent, a TT-935 thickener and water. The prepared product has formaldehyde adsorbing and decomposing effects.

Description

technical field

[0001] The invention relates to the field of building materials, in particular to a diatom coating capable of absorbing and decomposing formaldehyde. Background technique

[0002] The sources of formaldehyde in the indoor environment are mainly furniture and fabrics, wood product fillers, construction sources, detergents, cosmetics, and personal products, among which artificial boards are the main sources. Formaldehyde has an irritating effect on the skin and mucous membranes. Inhalation of formaldehyde can cause symptoms such as dizziness, headache, fatigue, and nausea. In severe cases, it can also cause infertility, fetal malformation, and carcinogenicity. According to GB / T18883-2002 "Indoor Air Quality Standard", the formaldehyde content in the air should be ≤0.10mg / m 3 , and many formaldehyde levels in indoor air exceed the national standard, which poses a threat to people's health.

Embodiment 1

[0036] Add 50.4 parts of water to the stirring tank, then add 2 parts of 5040 type dispersant, 0.1 part of 405 type wetting agent, 0.3 part of AGITAN-208 type defoamer, 0.3 part of 400 type polyethylene glycol and 0.3 part of 2-amino- 2-methyl-1-propanol, and stir well. Then add 2 parts of Cu / Al to the stirred tank 2 o 3 Type catalyst, 2 parts of nano-tungsten trioxide and 2 parts of anatase nano-titanium dioxide, and slowly drop 0.5 parts of Kh-570 type silane coupling agent, and stir at high speed to make it evenly dispersed. Finally, add 45 parts of diatomaceous earth to the stirring tank to continue the dispersion, and slowly add 0.1 part of TT-935 thickener, and stir evenly at a medium speed to obtain a diatomite dispersion loaded with decomposable formaldehyde materials for future use.
