The interior wall paint is composed of 40% of silicon acrylic emulsion, 15% of 1250 mesh talcum powder, and 3% of activated carbon powder with a particle size of not more than 100 microns in terms of weight percentage. 、Na 2 SO 3 5% doped modified bentonite, 6% nano-titanium dioxide with a particle size not greater 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 application method comprises the steps:

[0038] 1) In the pre-treatment process, the wall surface to be painted is first polished with sandpaper, and then the surface is dedusted;

[0039] 2) Spray the primer, first spray the pre-treated wall with ordinary primer, dry at 45°C for 3 hours and then polish;

[0040] 3) Spray the primer again, step 2) Spray the primer again on the wall after treat...

Embodiment 3

[0045] A method for applying an interior wall paint that absorbs and decomposes formaldehyde. The interior wall paint consists of 32% of styrene-acrylic emulsion, 20% of 1250 mesh talc powder, and 4% of activated carbon powder with a particle size of not more than 100 microns. 、Na 2 SO 3 4% doped modified bentonite, 8% nano-titanium dioxide with a particle size not greater than 100 nanometers, 5% nano-titanium phosphate, 16% pigments and additives, and 11% water, of which Na 2 SO 3 Doped modified bentonite, Na 2 SO 3 Account for 18%; Described application method comprises the steps:

[0046] 1) In the pre-treatment process, the wall surface to be painted is first polished with sandpaper, and then the surface is dedusted;

[0047] 2) Spray the primer, first spray the pre-treated wall with ordinary primer, dry at 46°C for 3 hours and then polish;

[0048] 3) Spray the primer again, step 2) Spray the primer again on the wall after treatment, dry at 46°C for 3 hours and then...

Abstract

The invention discloses an applying method for interior wall paint capable of absorbing and decomposing formaldehyde. The interior wall paint comprises the following active ingredients in percentage by weight: 30-45% of film forming base stock, 10-30% of filler, 1-4% of activated carbon powder, 3-5% of Na2SO3-doped modified bentonite, 3-8% of nanometer titanium dioxide, 2-5% of nanometer titanium phosphate, 11-20% of pigment and auxiliaries, and the balance of water, wherein Na2SO3 accounts for 16-30% of the Na2SO3 doped modified bentonite. The applying method comprises procedures of pretreating a wall surface, painting two layers of bottom-layer paint, and applying three-four layers of paint. The paint applied by adopting the applying method is not cracked and not peeled, the method is simple and easy to implement, and the applying effect is attractive and practical.

Description

technical field [0001] The invention relates to the field of chemical coatings, in particular to a method for applying 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 deco...
