Abstract
The invention provides a catalyst for removing indoor formaldehyde pollution. The catalyst is prepared by successively dissolving 1-4% of titanium dioxide, 2-5% of diammonium hydrogen phosphate, 1-3% of JFC penetrating agent, 1-5% of sodium dodecylbenzene sulfonate, 1-3% of urea peroxide, 0.1-0.5% of polyacrylamide, 1-4% of citric acid, 1-3% of chitosan, 2-4% of sodium sulphite and 1-2% of sodium carbonate in 65-85% water. The catalyst for removing indoor formaldehyde pollution can solve the formaldehyde pollution thoroughly brought by indoor decoration and furniture.
Description
Technical field
The present invention relates to chemical field, be specifically related to a kind of Formaldehyde Pollution of Indoor Air and remove catalyst.
Background technology
The housing industry of China is interior over the next several years will continue maintenance high speed development situation, and the annual newly-increased area of residence 500,000,000 square metres, has the old room of 600,000,000 square metres to carry out decoration renovation in addition every year.Along with the development of Chinese architecture adnornment industry, within 2010, building decorating industry has become the large industry of You18Wan Jia enterprise, more than 1,400 ten thousand practitioners, 1.85 trillion yuan annual value of production in China; Since nearly 20 years, rapidly, annual growth is by about 20%, and these data are far away higher than the growth rate of the GDP same period for the development of Chinese architecture adnornment industry.
Meanwhile, a large amount of synthetic material is widely used in interior decoration and finished product furniture, the volatility toxic compounds such as the formaldehyde that they discharge cause serious pollution to indoor environment, it is the main inducing of cancer, breathing problem, leukaemia, immunity reduction, fetus teratogenesis etc., the various disease caused thus and indoor environment case, had a strong impact on physical and mental health and the normal life of the people.Room air pollution becomes the another killer of infringement human health.Under such background, " IAQ national standard " that China formulates and relevant laws and regulations are also formally implemented.Air pollution problem inside rooms also receives unprecedented attention, and the demand of indoor air purification goods and environmental friendly indoor service is growing.According to the annual finishing area of residence and the estimation of the decorative craft output value, the current formaldehyde scavenger market capacity of China is with higher than 10,000,000,000 yuan (disregarding the public place such as hotel, office building finishing), and the enhancing along with people's environmental consciousness and the attention to health, the market capacity of formaldehyde scavenger estimates the speed increment with annual more than 30.
It is at present, indoor that what directly endanger human body is the free formaldehyde that pollution sources place evaporate in air:
In glue series products production process, the chemical addition agent unreacted containing formaldehyde completely part can produce free formaldehyde, progressively outwardly discharges;
Wood-based plate is in hot-press solidifying process, and a part fails to generate stable network structure containing the glue class material of formaldehyde composition, thus resolves into free formaldehyde and outwards discharge;
Can be there is reversible reaction in the resin glue after partially cured, decompose and discharge free formaldehyde under the effect of other chemical materials such as temperature and humidity.
Summary of the invention
For solving the problems of the technologies described above, a kind of Formaldehyde Pollution of Indoor Air is the object of the present invention is to provide to remove catalyst based on formaldehyde pollution source and process free formaldehyde, the removing of the inner formaldehyde of sheet material and free formaldehyde all there is very good effect, thoroughly can solve interior decoration and furniture brings formaldehyde pollution.
Formaldehyde Pollution of Indoor Air of the present invention removes catalyst, and formula is calculated by weight percentage, is made up of following component:
Preferably,
The particle diameter of described titanium dioxide is 4-5 nanometer, and further, the content of described titanium dioxide is 4%.
The content of described diammonium hydrogen phosphate is 5%.
The content of described careless acid dihydrazide is 5%.
The content of described carbamide peroxide is 3%.
Preparation method of the present invention is as follows: by above-mentioned formula, also soluble in water in proportion by said components order, stirs and can prepare product of the present invention.
The present invention dominates for aldehydes removal with diammonium hydrogen phosphate, careless acid dihydrazide, carbamide peroxide, adds other catalysis, product tool that decontamination, film forming, the suitable proportioning of infiltration composition are made has the following advantages:
1, containing the chemical bond of formaldehyde ion, the generation of free formaldehyde can not can effectively be stoped by immediate stability sheet material.
2, also can destroy and decompose by rapid adsorption periphery free formaldehyde, playing the object removing Indoor Air Formaldehyde.
3, product is neutral aqueous solution, corrosion-free effect, can not have infringement to the plank sprayed, metal or article.
4, the present invention is formed by nontoxic conventional base stock (being usually used in the aspect such as medical science, food additives) copolymerization hybrid modulation, has aldehydes removal and also possesses outward except the clean effect of benzene, and can not damage the person.
5, product has bleeding agent adhesive ability, in the nonexpendable situation of catalyst self, the long-time same formaldehyde remained in various decoration material reacts, destroy and colourless nontoxic, the material that do not produce inverse reaction of material that decomposing formaldehyde produces, secondary pollution can not be caused to environment.
6, of many uses:
(1), the artificial boards such as glued board, medium-density plate, lumber core, particieboard can be directly used in;
(2), can be used for the furniture, wardrobe, composite floor board, automobile liner, carpet etc. fitting up or buy;
(3) room, to fitting-up, is sprayed on wall and can forms aldehydes removal sweeping field.
Detailed description of the invention
Can understand the present invention further by specific embodiments of the invention given below, but they not limitation of the invention.For some nonessential improvement and adjustment that those skilled in the art does according to foregoing invention content, be also considered as dropping in protection scope of the present invention.
In addition, unless stated otherwise, the number adopted in the present invention is all weight percentage.
Embodiment 1
By following formula preparation product of the present invention:
Also soluble in water in proportion by said components order, stir.
Be noted that wherein JFC bleeding agent is AEO.
Embodiment 2
By following formula preparation product of the present invention:
Also soluble in water in proportion by said components order, stir.
Embodiment 3
By following formula preparation product of the present invention:
Also soluble in water in proportion by said components order, stir.
The product Formaldehyde Pollution of Indoor Air of the present invention prepared in embodiment 1-3 is removed catalyst, and carry out purifying formaldehyde performance test respectively, result of the test is in table 1.
