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

A kind of formaldehyde eliminating agent
Technical field
The present invention relates to the technical field of remover, more particularly relate to a kind of solvent that can eliminate formaldehyde.
Background technology
At present, after family is fitted up, if used do not reach the ornament materials of environmental requirement after, this material will discharge a kind of pernicious gas that contains formaldehyde, absorption of human body is this can poison after containing the gas of formaldehyde, go back the life security of entail dangers to when serious to the people, therefore, after family is fitted up, just need eliminate the indoor harmful substance that contains formaldehyde, to guarantee that indoor pernicious gas can not surpass state specified standards, otherwise will have influence on people's health, the method of noxious air is to utilize formaldehyde eliminating agent in the decontamination chamber that people adopt usually, utilize this formaldehyde eliminating agent just at an easy rate decontamination chamber contain the pernicious gas of formaldehyde material, as a application number is 01133329, the applying date is October 23 calendar year 2001, denomination of invention is the Chinese invention patent of formaldehyde remover, it is by triethanolamine, Sodium Metabisulfite, disodium ethylene diamine tetraacetate, 2,3,4,5, the aqueous solution that 6-penta hydroxy group hexanal and distilled water are formed, triethanolamine wherein, Sodium Metabisulfite, disodium ethylene diamine tetraacetate, 2,3,4,5,6-penta hydroxy group hexanal, the consumption of distilled water is respectively 0.9-1.1 part, 0.22-0.28 part, 0.22-0.28 part, 0.2-0.6 part, 125 parts (above all by weight) make concentrate, before the application again with it with distilled water diluting to 1000 part (weight meter).Utilize the formaldehyde eliminating agent of method for preparing, needed raw material is many during its preparation, preparation cost is high.
Summary of the invention
Purpose of the present invention is exactly that needed raw material is few when providing a kind of preparation in order to solve above-mentioned deficiency, preparation cost is low, and can remove a kind of formaldehyde eliminating agent of formaldehyde harmful substance in indoor and the indoor furniture effectively.
The technical solution that the present invention adopts in order to solve the problems of the technologies described above is as follows:
A kind of formaldehyde eliminating agent, it forms (percentage by weight) by following component:
Amine compound 1%-50%
Cyanamide compounds 0.5%-30%
The water-soluble high-molecular compound 0.1%-20% of hydroxyl
Titanium dioxide 0.8%-1.5%
Water 1%-30%.
Described amine compound is the urea element.
Described cyanamide compounds is a dicyandiamide.
The water-soluble high-molecular compound of described hydroxyl is CMC.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is: its needed raw material is few, low cost of manufacture, and can very remove the formaldehyde pollutant of air in indoor and the indoor furniture effectively, thereby purify our living space, the elimination factor of PARA FORMALDEHYDE PRILLS(91,95) can reach 90%, and titanium dioxide can utilize nano titanium oxide, behind the adding nano titanium oxide, not only the formaldehyde pollutant can be removed effectively, airborne other noxious pollutant can also be disposed.
The specific embodiment
A kind of formaldehyde eliminating agent, it forms (percentage by weight) by following component: the water-soluble high-molecular compound 8% of urea element 45%, dicyandiamide 20.5%, hydroxyl, nano titanium oxide 1.5% and water 25%.
Formaldehyde eliminating agent, it can also form (percentage by weight) by following component: the water-soluble high-molecular compound 10% of urea element 40%, dicyandiamide 30%, hydroxyl, nano titanium oxide 1% and water 19%.
Wherein the chemical equation of amine compound and formolite reaction is:
H 2N-R+HCHO→R-HN-CH 2-OH
The chemical equation of cyanamide compounds and formolite reaction:
TIO 2Photocatalysis mechanism:
As the photon irradiation TiO of wavelength less than 387.5nm 2Behind the surface, the electronics that is in valence band will be excited to conduction band and get on, thereby produces highly active photohole (h+) and e-respectively on valence band and conduction band:
TiO 2+hv→h ++e-(1)
Under different condition, h+ and e-generate hydroxyl radical free radical (OH) through series reaction.
Under high pH condition, OH easily passes through the OH-Direct Transfer to photoactive TiO 2The surface, capture photohole and produce:
h ++OH -→·OH (2)
Under low pH condition, OH easily passes through H +With the O that is adsorbed 2 -Series (O -, O 2 -, O 2 2-, O 3 -) combination, forming H 2O 2The basis on further generate:
e -+O 2→·O 2 - (3)
·O 2 -+H +→HO 2· (4)
2HO 2 ·→O 2+H 2O 2 (5)
H 2O 2+·O 2 -→·OH+OH -+O 2(6)
HO 2 ·+·O 2 -→HO 2 -+O 2 - (7)
HO 2 -+H +→HO 2 · (8)
In addition, the h+ that is produced also can directly be oxidized to OH with the hydrone that is adsorbed on the TiO2 surface:
2H 2O+h +→·OH+H 3O + (9)
Through the OH that above-mentioned reaction produced, the adjacent with it organic pollution of energy oxidation also can be diffused into oxidation organic pollution in the liquid phase.In addition, many organic pollutions also can be directly by the h+ oxidation.
