Abstract
The invention relates to a nanometer silver formaldehyde eradicating-liquid, which is formed by triethanolamine, sodium sulfite, complexon, amchlor, amylaceum, water and water-soluble colloidal silver, wherein the average diameter of water-soluble colloidal silver is 1-100nm; said eradicating-liquid can quickly disinfect bacillus coli, etc, and reduce the free formaldehyde density under 0.08mg/m3, while the virus disinfection rate is above 90%. The invention also discloses a relative preparation.
Description
Technical field
The present invention relates to a kind of formaldehyde but also nano silver-group formaldehyde eradicating-liquid that can antibiotic (antibacterial) not only can removed; The invention still further relates to the preparation method of this nano silver-group formaldehyde eradicating-liquid.
Background technology
Along with the enhancing of people's environmental consciousness, people are also more and more higher to the requirement of house decoration, living environment, and people generally pay attention to the quality of family's indoor environment.What influence indoor environmental quality mainly is indoor air pollutants, mainly is to be the organic toxic gas of representative with formaldehyde, and main in addition is bacterium, mainly with Escherichia coli and staphylococcus aureus etc., and people's immediate cause of falling ill often.
The formaldehyde scavenger of having reported, the formaldehyde catching agent kind is more, product functions such as Chinese patent CN1463753A, CN1104657A and CN1526470A are single as has been publicly, lack comprehensive removing indoor pollution material, can only be single decomposition or absorbing formaldehyde, and do not possess bactericidal effect, and the pollution of being not only volatile materials such as formaldehyde, benzene, ammonia, TVOC that often touches in people's living environment, also having a lot of bacteriums is influencing people's normal life.
Summary of the invention
At the above-mentioned deficiency of prior art, one of technical problem to be solved by this invention is to propose a kind ofly both can to remove formaldehyde, nano silver-group formaldehyde eradicating-liquid that also can antibiotic (antibacterial).
Two of technical problem to be solved by this invention is the preparation methods that propose above-mentioned nano silver-group formaldehyde eradicating-liquid.
The present invention one of solves the problems of the technologies described above the technical scheme that adopts to be: this nano silver-group formaldehyde eradicating-liquid is made up of following components in weight percentage:
Triethanolamine 0.3-2%;
Sodium Metabisulfite 0.05-0.5%;
Disodium ethylene diamine tetraacetate 0.05-0.5%;
Ammonium chloride 0.5-2%;
Glucose 0.1-2%;
Water-soluble colloid silver 0.005-0.01%;
Surplus is a water; Wherein
The average grain diameter of water-soluble colloid silver is 1-100nm.
Nano silver-group formaldehyde eradicating-liquid of the present invention is made up of two kinds of functional components, and a kind of is formaldehyde eliminating solution function solution, is made up of triethanolamine, Sodium Metabisulfite, disodium ethylene diamine tetraacetate, ammonium chloride, glucose and water; Another kind is antibiotic, antibacterial base-material, is selected from water-soluble colloid silver.Nano silver particles evenly distributes in liquid phase, and good dispersion does not precipitate.
The preparation method of the above-mentioned nano silver-group formaldehyde eradicating-liquid of the present invention is as follows: water-soluble colloid silver is added in the entry, stir, add triethanolamine, Sodium Metabisulfite, disodium ethylene diamine tetraacetate, ammonium chloride and glucose more successively, stir at normal temperatures, until uniform dissolution, filter, promptly get slightly faint yellow transparent nano silver-group formaldehyde eradicating-liquid.
Nano silver-group formaldehyde eradicating-liquid of the present invention uses at the more serious artificial board of pollution, carpet, furniture, wallpaper etc. and locates, and removes formaldehyde, eliminates peculiar smell, kill bacteria, create formaldehydeless, abacterial clean environment, conscientiously ensure people's healthy living, improve people's living standard.
With respect to prior art, the present invention utilizes nano silver particles to be distributed to have formaldehyde to eliminate in the aqueous solution of function, and its system is homogeneous phase, does not have precipitation, has the following advantages:
1, this nano silver-group formaldehyde eradicating-liquid can be eliminated free formaldehyde rapidly, does not need particular surroundings and temperature in the use.
2, this nano silver-group formaldehyde eradicating-liquid is that pH value is the neutral aqueous solution, and no corrosiveness can not have infringement to sheet material or the article surface that sprays.
3, this nano silver-group formaldehyde eradicating-liquid is light yellow transparent liquid slightly, and is nontoxic, tasteless, do not produce secondary pollution.
4, this nano silver-group formaldehyde eradicating-liquid is removed free formaldehyde efficient height, and very strong antibacterial and bacteriostasis is arranged.Decorate indoor environment monitoring center of association through China and detect, eliminate the formaldehyde rate more than 90%; When nano silver particles concentration is 100PPM, through Shanghai Disease Prevention and Control Centre check, to Escherichia coli and staphylococcus aureus (ATCC6538) bacteriostasis rate more than 90%.
5, this nano silver-group formaldehyde eradicating-liquid production technology is simple, easy to use.
