Abstract
A formaldehyde eliminating agent for indoor space is proportionally prepared from amino compound, cyanamine compound, water-soluble high-molecular hydroxy compound, water, and TiO2.
Description
Technical Field
The invention relates to the technical field of an eliminating agent, in particular to a solvent capable of eliminating formaldehyde.
Background
At present, after a home is decorated, if a decorative material which does not meet the requirement of environmental protection is used, the material can release harmful gas containing formaldehyde, a human body can be poisoned after absorbing the gas containing formaldehyde, and the life safety of people can be seriously threatened, so after the home is decorated, the harmful substance containing formaldehyde in a room needs to be eliminated to ensure that the harmful gas in the room cannot exceed the national standard, otherwise, the health of people can be influenced The watersolution is composed of sodium metabisulfite, ethylene diamine tetraacetic acid, 2, 3, 4, 5, 6-pentahydroxyhexanal and distilled water, wherein the dosage of triethanolamine, sodium metabisulfite, ethylene diamine tetraacetic acid disodium, 2, 3, 4, 5, 6-pentahydroxyhexanal and distilled water is 0.9-1.1 parts, 0.22-0.28 parts, 0.2-0.6 parts and 125 parts (by weight) respectively to prepare concentrated solution, and the concentrated solution is diluted to 1000 parts (by weight) by distilled water before application. The formaldehyde remover prepared by the method needs more raw materials and has high preparation cost.
Disclosure of Invention
The invention aims to solve the defects and provide a formaldehyde remover which needs less raw materials during preparation, has low preparation cost and can effectively remove harmful substances of formaldehyde in indoor and indoor furniture.
The technical solution adopted by the present invention to solve the above technical problems is as follows:
a formaldehyde eliminating agent comprises the following components (by weight percent):
1 to 50 percent of amino compound
Cyanamide compound 0.5-30%
0.1-20% of water-soluble macromolecular compound containing hydroxyl
0.8 to 1.5 percent of titanium dioxide
1 to 30 percent of water.
The amine-based compound is urea.
The cyanamide compound is dicyandiamide.
The water-soluble polymer compound containing a hydroxyl group is CMC.
The invention adopts the technical proposal to achieve the following beneficial effects: the formaldehyde removingagent has the advantages of less raw materials and low manufacturing cost, and can effectively remove formaldehyde pollutants in air in indoor and indoor furniture, so that the living space of people is purified, the formaldehyde removal rate can reach 90%, and the titanium dioxide can utilize nano titanium dioxide, and after the nano titanium dioxide is added, the formaldehyde pollutants can be effectively removed, and other harmful pollutants in the air can be removed.
Detailed Description
A formaldehyde eliminating agent comprises the following components (by weight percent): 45% of urea, 20.5% of dicyandiamide, 8% of water-soluble macromolecular compound containing hydroxyl, 1.5% of nano titanium dioxide and 25% of water.
The formaldehyde eliminating agent can also comprise the following components (by weight percent): 40% of urea, 30% of dicyandiamide, 10% of water-soluble macromolecular compound containing hydroxyl, 1% of nano titanium dioxide and 19% of water.
The chemical equation of the reaction of the amino compound and formaldehyde is as follows:
chemical equation of reaction of cyanamide compound and formaldehyde:
TIO2the mechanism of photocatalytic action of (a):
when photons with the wavelength of less than 387.5nm irradiate the TiO2After the surface, electrons in the valence band are excited to the conduction band, so that highly active photogenerated holes (h +) and e-are generated in the valence band and the conduction band respectively:
under different conditions, h + and e-undergo a series of reactions to generate hydroxyl radicals (. OH).
TiO with OH easy to directly transfer to photoactivity through OH-under high pH conditions2A surface, trapping photo-generated holes to generate:
at low pH,. OH readily passes through H+With adsorbed O2 -Series (O)-，O2 -，O2 2-，O3 -) Is combined to form H2O2Further generating:
furthermore, the h + generated can also directly oxidize water molecules adsorbed on the surface of TiO2 to OH:
the OH generated by the above reaction canoxidize the adjacent organic pollutants, and can also diffuse into the liquid phase to oxidize the organic pollutants. In addition, many organic contaminants can also be directly oxidized by h +.
