The interior wall paint consists of 30% of acrylic resin, 20% of 1250 mesh heavy calcium powder, 2% of activated carbon powder with a particle size of not about 100 microns, and Na 2 SO 3 3% doped modified bentonite, 3% nano-titanium dioxide with a particle size of less than 100 nanometers, 5% nano-titanium phosphate, 12% pigments and additives, and 25% water, of which Na 2 SO 3 In doped modified bentonite, Na 2 SO 3 Account for 16%; Described method comprises the steps:

[0026] (1) At the speed of the mixer at about 1500r / min, Na 2 SO 3 Mix and stir with bentonite according to the ratio and add appropriate amount of water to adjust it into a paste, stir for about 20 minutes, and put it in a container for later use;

[0027] (2) At the speed of the mixer at about 500r / min, add nano-titanium dioxide and nano-titanium phosphate into an appropriate amount of water, mix and stir ...

Embodiment 2

[0031] A method for preparing an interior wall paint that absorbs and decomposes formaldehyde. The interior wall paint consists of 40% of silicon acrylic emulsion, 15% of 1250 mesh talc powder, 3% of activated carbon powder with a particle size of not about 100 microns, and Na 2 SO 3 5% doped modified bentonite, 6% nano-titanium dioxide with a particle size of less than 100 nanometers, 3% nano-titanium phosphate, 14% pigments and additives, and 14% water, of which Na 2 SO 3 In doped modified bentonite, Na 2 SO 3 Account for 15%; Described method comprises the steps:

[0032] (1) At the speed of the mixer at about 1800r / min, Na 2 SO 3 Mix and stir with bentonite according to the ratio and add appropriate amount of water to adjust it into a paste, stir for about 15 minutes, and put it in a container for later use;

[0033] (2) At the speed of the mixer at about 1000r / min, add nano-titanium dioxide and nano-titanium phosphate into an appropriate amount of water, mix and st...

Embodiment 3

[0037]A method for preparing an interior wall paint that absorbs and decomposes formaldehyde. The interior wall paint consists of 32% styrene-acrylic emulsion, 20% 1250 mesh talc powder, 4% activated carbon powder with a particle size of not about 100 microns, and Na 2 SO 3 4% doped modified bentonite, 8% nano-titanium dioxide with a particle size of less than 100 nanometers, 5% nano-titanium phosphate, 16% pigments and additives, and 11% water, of which Na 2 SO 3 In doped modified bentonite, Na 2 SO 3 Account for 18%; Described method comprises the steps:

[0038] (1) At the speed of the mixer at about 1600r / min, Na 2 SO 3 Mix and stir with bentonite according to the ratio and add appropriate amount of water to adjust it into a paste, stir for about 18 minutes, and put it in a container for later use;

[0039] (2) At the speed of the mixer at about 800r / min, add nano-titanium dioxide and nano-titanium phosphate into an appropriate amount of water, mix and stir for abou...

Abstract

The invention discloses a method for preparing an interior wall coating material for absorbing and decomposing formaldehyde. The method comprises the following steps: (1) mixing and stirring Na2SO3 and bentonite according to a ratio at a speed of about 1500-1800 revolutions per minute of a stirrer, adding a proper amount of water, regulating into paste, stirring about 15-20 minutes, and putting the paste into a container for later use; (2) adding nanometer titania and nano titanium phosphate into the proper amount of water at the speed of about 500-1000 revolutions per minute of the stirrer, mixing and stirring for about 10-15 minutes, forming uniform slurry, and putting the slurry into the container for later use; (3) adding a film-forming base material, filler, pigments and auxiliaries into the residual water, uniformly mixing at the speed of about 1000 revolutions per minute of the stirrer, and preparing the slurry; and (4) adding the slurry prepared in the steps (1) and (2) into the slurry prepared in the step (3) at the speed of about 500 revolutions per minute, mixing and stirring for about 10-15 minutes, adding activated carbon powder, and stirring for about 20-30 minutes.

Description

technical field [0001] The invention relates to the field of chemical coatings, in particular to a preparation method of an interior wall coating that absorbs and decomposes formaldehyde. Background technique [0002] Formaldehyde is contained in paints such as wood, boards, furniture, walls, etc. in the family room, but what is even more frightening is that the release period of formaldehyde is generally three to fifteen years. The No. 153 Bulletin released by the World Health Organization in 2004 determined that formaldehyde is a carcinogenic and teratogenic substance. Formaldehyde is a recognized allergen, is also one of the potential strong mutagen, and is also one of the risk factors leading to childhood leukemia. According to domestic medical journals and related literature reports, the hazards of indoor formaldehyde to human health can be summarized as stimulating, toxic and carcinogenic. [0003] Nano-materials can generate negative ions and have the function of de...
