Problems solved by technology

With the continuous improvement of people's quality of life, the requirements for environmental protection and health are getting higher and higher. The further requirement for coatings (interior wall paints) is to purify indoor harmful gases such as formaldehyde. At present, air-purifying coatings (interior wall paints) have appeared on the market. , such as Chinese patents: application number 200810243214.6, application number 200910222118.8, wherein titanium dioxide is used as a photocatalyst to achieve the purpose of purifying formaldehyde, but the purification effect of these net aldehyde coatings (interior wall paint) is not i

Example Embodiment

[0051] Example 1

[0052] Put 35 parts of water into the stainless steel barrel, add 0.2 part of wetting agent, 0.3 part of defoamer, 0.5 part of dispersant, 8 parts of titanium dioxide, 12 parts of Active silicon, 0.96 parts Ag-AgBr-TiO on active silicon 2 , 11 parts of heavy calcium, 10 parts of wollastonite, and 4 parts of kaolin, uniformly dispersed for 30min at the rotating speed. The rotating speed was adjusted to 800 r / min, and the above dispersion system was stirred at this rotating speed, and 16 parts of the emulsion was slowly added at the same time, and the rotating speed was maintained for uniform dispersion for 15 min. Adjust the rotation speed to 500r / min, stir the above emulsion at this rotation speed, and slowly add 0.4 parts of cellulose, 0.5 parts of ethylene glycol, 0.6 parts of leveling agent, 0.5 parts of film-forming aids, and keep the rotation speed. After 20min of uniform dispersion, add an appropriate amount of pH adjuster to adjust the pH within the...

Abstract

The invention relates to an environment protection-type interior wall paint with a formaldehyde purification function and a preparation method therefor. The paint comprises the following ingredients, by weight, 30-40 parts of water, 3-20 parts of titanium dioxide powder, 9-20 parts of active silicon, 0.5-5 parts of active silicon supported Ag-AgBr-TiO2, 3-5 parts of kaolin and 12-18 parts of emulsion. The active silicon and the active silicon of the active silicon supported Ag-AgBr-TiO2 are both a synthesized product with fly ash as a raw material, and the synthesized product is white powder. Then Ag-AgBr-TiO2 components are loaded on surfaces of the active silicon material through physical absorption, and the mass fraction of Ag-AgBr-TiO2 in the active silicon material is 5-10%. The paint can degrade formaldehyde into CO2 and H2O under a daylight lamp or normal sun light, and is an environment protection paint with a function of purifying indoor harmful gases such as formaldehyde and the like.

Description

technical field [0001] The invention relates to an environment-friendly interior wall paint and a preparation method thereof, in particular to an environment-friendly interior wall paint (interior wall paint) with the function of purifying indoor harmful gases such as formaldehyde and a preparation method thereof, belonging to the technical field of paint. Background technique [0002] Indoor harmful gases such as formaldehyde are harmful substances contained in materials such as building materials, decoration materials and furniture, which are gradually released and endanger human health for a long time. For example, free monomers in emulsions and additives in architectural coatings are prone to produce a large amount of harmful volatiles such as VOC, formaldehyde, and benzene. These volatiles will not only pollute the environment, but also seriously endanger human health and easily cause chronic respiratory diseases. , leukemia, etc. In response to such problems, internat...
