The present invention provides a kind of Tea Polyphenols formaldehyde remover, by following percentage by weight into being grouped into：Tea Polyphenols 0.5~1.5%, methanal trapping agent 3~5%, nano-silver colloid 4~8%, balance of water.The Tea Polyphenols formaldehyde remover for providing is provided, formaldehyde pollutants can be highly desirable removed, living space is purified.
Description
Technical field
The present invention relates to a kind of formaldehyde remover, more particularly to a kind of Tea Polyphenols formaldehyde remover.
Background technology
Formaldehyde is one of organic gaseous contamination thing of indoor most serious, with toxicity very high, in June, 2004 World Health Organization world cancer
Claiming the formaldehyde of high concentration in the report that disease research center (IARC) is delivered can cause ear nose larynx cancer and other body illnesses, poisonous in China
On chemicals priority acccess control list, first is dioxin, and second is formaldehyde, therefore, formaldehyde is very big to human health risk.Now such as
The present, people are more and more universal to the finishing of office, meeting room and living quarter etc., and the seal to space requires also more and more higher so that
The exchange of indoor and outdoor air is fewer and feweri.When national health, construction and environmental administration spot-check to house decorative material it has been found that：With dirt
The material for contaminating gas accounts for 68%, and these ornament materials can volatilize formaldehyde, dichloroethylene, benzene, dimethylbenzene etc. more than 300 in use
Volatile organic compound is planted, once get in air it is absorbed by the body, it will trigger various health diseases.According to Chinese preventive medicine division
Institute provide data, people in life more than 2/3 time all spend indoors, especially infant, children and adolescents and
The old,weak,sick and disabled person, therefore, harm of the indoor environmental pollution to human health is the most direct, and the extent of injury is bigger.Due to room air pollution
Harmfulness and generality, there is expert to think after " coal-smoke pollution " and " pollution of photochemical fog type ", modern be in
" room air pollution " is the 3rd pollution period of mark, and the prevention of organic gaseous contamination turns into the ring that can not be ignored with oneself is administered in room air
Border problem.
The formaldehyde of the person is endangered, following several approach are mainly derived from：
First, the indoor formaldehyde pollution that house fitting is caused is come from, the People's Republic of China (PRC)《Formaldehyde sanitary standard in indoor air》(GB/T
16127-1995) specify, occupy the acceptable concentration upper limit of indoor formaldehyde amount for 0.08mg/m 3, but concentration of formaldehyde average out to after general house decoration
0.2mg/m 3, reaches as high as 0.81mg/m 3, severe overweight.
Second, coming from the formaldehyde pollution of separate out in artificial board, finishing material, textile
Formaldehyde can be used to synthesize various adhesives, coating or textile auxiliary as industrial chemicals.All kinds of chemical products with formaldehyde as Material synthesis,
The finishing materials such as glued board, the particieboard artificial board used in such as fitting up, wallpaper, wall paper and paint, or textile etc., using
In can all have the formaldehyde separate out of residual.
For above-mentioned two classes formaldehyde pollution, formaldehyde remover product, generally comes according to the processing mode of physical absorption or chemisorbed in the market
Removing residue formaldehyde is eliminated, but there is technological deficiency.
In sum, how the weak point of formaldehyde remover on existing market is improved, develop it is a kind of efficiently, the formaldehyde remover of environmental protection,
It is the technical barrier of those skilled in the art's urgent need solution.
The content of the invention
The present invention provides a kind of Tea Polyphenols formaldehyde remover, and ingredient asepsis environment-protecting can efficiently remove formaldehyde, applied widely, solve
Defect existing for above-mentioned prior art.
For achieving the above object, this invention takes following technical scheme：
A kind of Tea Polyphenols formaldehyde remover, by following percentage by weight into being grouped into：Tea Polyphenols (No. CAS：84650-60-2) 0.5~1.5%,
Methanal trapping agent 3~5%, nano-silver colloid 4~8%, balance of water.
The Tea Polyphenols, Tea Polyphenols are the general names of Polyphenols of Tea, including flavanol compound, anthocyanin class, flavonoids,
Flavonols and phenolic acid class etc..Predominantly flavanols (catechin) class, catechin accounts for 60~80%.Class material Tea Polyphenols also known as tea tan or
Tea tannin, is one of the Main Ingredients and Appearance to form tealeaves color, smell and taste, is also have one of Main Ingredients and Appearance of healthcare function in tealeaves.Research shows, tea
The removing toxic substances of polyphenol isoreactivity material tool and radiation resistance, can effectively prevent radioactive substance from invading marrow, and strontium 90 and Co 60 can be made rapid
Excrete, be described as " radiation jinx " by health and medical field.
The nano-silver colloid, can use commercially available nano-silver colloid, it would however also be possible to employ following methods are prepared from：
By the cyclodextrin aqueous solution of 0.1wt% with molality for the silver ammino solution of 0.1mol/L is mixed with 1: 50 volume ratio,
40min is stirred under 80 DEG C of temperature conditionss, that is, it is the nano-silver colloid of 5-20nm to obtain average grain diameter.
Wherein, the preparation method of silver ammino solution is：The sodium hydroxide solution of 0.1mol/L is added dropwise in the silver nitrate solution of 1.0mol/L, is occurred
White precipitate, is then added dropwise the ammonia spirit of 5wt%, until white precipitate disappears, obtains the silver-colored ammonia that molality is 0.1mol/L
Solution.
Cyclodextrin in the cyclodextrin aqueous solution for 2-O- (hydroxypropyl-N, N- dimethyl-N-hexadecyl base ammonium)-beta-schardinger dextrins and/or
