Embodiment 1

[0017] A kind of interior wall formaldehyde-removing paint, it is made up of the following raw materials of weight part:

[0018] Silicone acrylic emulsion 130, diatomaceous earth dispersion 40, sodium potassium tartrate 2, dodecyltrimethylammonium chloride 4, diisocyanate 2, barium naphthenate 2.

[0019] The preparation method of described diatomite dispersion liquid, comprises the following steps:

[0020] Take 20 parts by weight of diatomaceous earth, mix with 2 parts by weight of polysorbate, stir evenly, add to deionized water 5 times the weight of the mixture, stir evenly, and obtain.

[0021] The preparation method of described interior wall removing formaldehyde paint, comprises the following steps:

[0022] (1) Take barium naphthenate, add it to chloroform that is 5 times its weight, stir evenly, add diisocyanate, increase the temperature to 55°C, keep stirring for 20 minutes, add silicon-acrylic emulsion, ultrasonic for 5 minutes, and distill off chloroform , to o...

Abstract

The invention discloses an interior wall formaldehyde-removal paint and a preparation method thereof. The interior wall formaldehyde-removal paint is prepared from, by weight, 100-130 parts of silicone acrylic emulsion, 20-40 parts of diatomaceous earth dispersion liquid, 1-2 parts of seignette salt, 2-4 parts of dodecyl trimethyl ammonium chloride, 1-2 parts of diisocyanate and 1-2 parts of barium naphthenate. The interior wall formaldehyde-removal paint and the preparation method thereof have the advantages that polysorbate dispersion is adopted, the surface activity of diatomaceous earth iseffectively improved, the compatibility of the diatomaceous earth with the silicone acrylic emulsion is improved, thereby improving the adsorption performance of a finished coating.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a formaldehyde-removing 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 decoration materials and furniture c...
