Abstract
The invention relates to an air purification spray for formaldehyde removal. Chitin and nano-silicon powder are taken as effective raw material components ,are proportioned properly and can sufficiently play a synergistic role, the finally prepared air purification spray for formaldehyde removal contains a large quantity of stable and unsaturated positive charge structures and active amino groups, so that on the one hand, the unsaturated positive charge structures are used for adsorbing small-molecular free formaldehyde and other substances, on the other hand, the active amino groups are used for decomposing free formaldehyde, formaldehyde is converted into equimolar water, and a reaction equation is CH2O+H2NR H2CNR+H2O; besides, the spray can produce a strong negative electric field, and the negative electric field can effectively kill harmful microorganisms and bacteria in the air while adsorbing free formaldehyde and VOCs (volatile organic compounds) in the air.
Description
Technical field
The invention belongs to air purification field, be specifically related to a kind of except formaldehyde air cleaning spray and preparation thereof
Method.
Background technology
The interior product category of indoor cart is various, used raw material substantially wood-base fibre and particle panel material, adhesive, skin
Leather, cloth, sponge, wallpaper, stone material, glass, pottery etc..Different qualities is used between various raw materials
Adhesive bonding, and in adhesive, a large amount of formaldehyde of content is as solvent, therefore, with product meeting in indoor cart
Constantly produce the volatile harmful material such as free formaldehyde, VOCs.Free formaldehyde is judged by World Health Organization (WHO)
For one-level carcinogen, the most releasable 15 years of the formaldehyde in wood-base fibre and particle panel material.
Windowing is the better method of volatile harmful material in release indoor cart, but the PM2.5 index of outdoor is remote
Higher than indoor.Window for a long time and can make the amount of dust accumulation superposition of indoor, be a kind of serious air pollution equally.
If haze sky, people dare not window at all, and therefore indoor formaldehyde just cannot eliminate.Night, Ren Menguan
Door is when closing window rest, and the indoor concentration of formaldehyde that dissociates is higher, and hazardness is bigger.
Conventional indoor air purification product has: (1) air purifier, acts primarily as filtration；(2)
Activated carbon, plays adsorption；(3) photocatalyst, with harmful gass such as decomposing formaldehydes, but can need effective light
Source, and preferably ultraviolet light；(4) amino-compound (ammonium chloride, carbamide etc.), reacts with formaldehyde,
But ammonia can be discharged, same contaminated air.
