Abstract

The invention discloses interior wall paint capable of absorbing and decomposing formaldehyde. The interior wall paint is characterized by comprising 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.

Description

technical field [0001] The invention relates to the field of chemical coatings, in particular to 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 decomposing formaldehyde. ...
