Problems solved by technology

[0003] At present, the main methods to remove formaldehyde and other harmful gases are ventilation and physical adsorption; many manufacturers produce adsorbents, but the effect is not ideal, and it is not environmentally friendly, and it is easy to cause secondary pollution; at the same time, the quality of traditional adsorbents is low and the recycling rate is low. , the microporous structure is easily damaged, reducing the adsorption effect

Abstract

The invention discloses formaldehyde-removing adsorption coating for an interior wall. The formaldehyde-removing adsorption coating is prepared from the following raw materials in parts by weight: 90to 100 parts of diatomite, 20 to 30 parts of modified silicone acrylic emulsion, 1 to 2 parts of ricinoleic acid, 0.4 to 1 part of 2-thiolbenzimidazole, 1 to 2 parts of sodium lauryl sulfate, 0.7 to 1part of sorbitan monooleate, 1 to 2 parts of calcium propionate and 2 to 3 parts of oleic acid polyoxyethylene ester. According to the formaldehyde-removing adsorption coating for the interior wall,the diatomite and the silicone acrylic emulsion have very good dispersion compatibility and a coating film has good uniform stability and high adsorption performance; the formaldehyde-removing adsorption coating is especially suitable for being used as interior wall coating and has a very good promotion effect on air purification and formaldehyde adsorption.

Description

technical field [0001] The invention belongs to the field of environmental protection, and in particular relates to a formaldehyde-removing adsorption coating for interior walls and a preparation method thereof. Background technique [0002] Harmful gases refer to gases that have adverse effects on the health of humans or animals, or that have no effect on the health of humans or animals, but make humans or animals feel uncomfortable and affect the comfort of humans or animals. Such as formaldehyde, H2S and aromatic hydrocarbons and so on. Relevant data show that indoor air pollution is 5-10 times higher than outdoor, and there are as many as 500 kinds of indoor air pollutants. Indoor air pollution has become the cause of many diseases, and formaldehyde is a major aspect of indoor air pollution. The problem of formaldehyde pollution is mainly concentrated in the living room, textiles and food. Plywood, fiberboard, particle board and other man-made panels in room decoratio...
