Abstract
The invention provides a nanometer silver anti-mildew spray used for quickly preventing furniture, carpets, walls, and the like from being mildewed. The nanometer silver anti-mildew spray contains nanometer silver, an additive agent, hydrogen peroxide and de-ionized water, wherein the additive agent comprises a thickening agent comprising one or more fiber polymer, such as methylcellulose, hydroxymethyl cellulose, polyanion cellulose, and the like. In the nanometer silver anti-mildew spray, local nanometer silver can be oxidized by the hydrogen peroxide, thereby the anti-mildew and sterilizing effects can be achieved. The nanometer silver anti-mildew spray can be used for quickly preventing mildew.
Description
One, technical field
The present invention relates to a kind of mildew resistant spraying agent.
Two, background technology
Indoor mould is very big to health effects.Mould often is hidden in carpet, furniture or each corner and the wall seam, and the most common with Stachybotrys atra and aspergillus niger, they present black and green.Live in the indoor of mould, maximum to the harm of suffering from bronchitis and sphagitis patient.Mould also possibly cause diseases such as Hay Fever and asthma in addition, and therefore immunity weak people possibly infect.Also can have a headache, phenomenon such as fever, skin or mucous membrane inflammation.
General mould just can breed above under 70% the situation in air humidity for a long time.China's southeastern coastal areas moisture is serious; Whenever plum rain season arrives; Air humidity keeps higher level for a long time, and the main residences in these areas are indoor just to begin to grow mould, is difficult to remove; Not only furniture, leather, wall, clothing etc. are damaged, the more important thing is to have a strong impact on the healthy of people.
Nano Silver (nano silver) is exactly that particle diameter is accomplished nano level argent simple substance.As the natural antibacterial agent of latest generation, bactericidal nano-silver has broad-spectrum antiseptic, have no drug resistance and the characteristics of safety non-toxic.
The mechanism of Nano Silver broad-spectrum antiseptic maybe be relevant with the combination of Nano Silver and protein and nucleic acid.Nano-Ag particles can combine with the metabolic enzyme of crying out sulfydryl after getting into thalline, causes bacterium and fungi dead; Nano Silver also possibly combine with the DNA of bacterium and fungi, causes its structural change, suppresses dna replication dna, causes fungi to lose activity.Domestic authoritative institution discovers: it has comprehensive antibacterial activity to pathogenic bacteria of drug-resistant such as resistance Escherichia coli, resistance staphylococcus aureus, drug-resistant pseudomonas aeruginosa, streptococcus pyogenes, enterococcus, anaerobic bacteria etc.; The common bacterium of burn and scald and wound surface such as staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Candida albicans and other G+, G-property pathogenic bacteria all there is bactericidal action; To chlamydia trachomatis, cause that the gonococcus of sexually transmitted disease also has very powerful bactericidal action.
In Compendium of Material Medica, put down in writing: give birth to silver, nontoxic; Explanation in U.S. public health bureau nineteen ninety " about the survey report of silver-colored toxicity ": silver does not have obvious toxic-side effects to human body; Nano Silver does not have any toxicity when mouse investigate is found in test at oral maximal tolerance dose 925ppm finds, in the skin irritation test of rabbit, does not also find any IR.
Domestic mould inhibitor is used for industrial circle more at present, does not also relate to aspect at home.Application number 200710190772.6 " a kind of novel nanometer mildew proofing agent " mainly applies to the mildew-resistant of cloth class, and the having relatively high expectations of nano particle, and also will carry out post processing, and the preparation process is loaded down with trivial details.
Three, summary of the invention:
The purpose that the present invention implements is to invent a kind of nano-silver mildew-proof agent, with the problem of the quick mildew-resistant protection that solves present furniture, carpet, wall etc.
The embodiment of the invention is achieved in that
It is compared with prior art a kind of that the present invention provides, for a long time the nano silver spray product of quick mildew-resistant.This spray is made up of Nano Silver, additive, hydrogen peroxide solution and deionized water.
Nano-silver mildew-proof agent among the present invention, wherein Nano Silver concentration is 20-500ppm, the additive mass percent is 0.5%-1%.
The hydrogen peroxide solution that uses among the present invention, volumetric concentration are 30%, and mass percent is 0.01%.
The deionized water that uses among the present invention, electrical conductivity are 0.3us/cm.
The Nano Silver that the present invention uses, particle diameter is 20-100nm, purity is not less than 90%, can use a kind of method preparation of discharge-induced explosion wire method, using vaporization condensation process, laser method, sol-gal process.
A kind of nano-silver mildew-proof agent contains Nano Silver and additive, and its additive is made up of thickener, and one or more form thickener by fibrid polymer such as methylcellulose, CMC, polyanion celluloses.
In the technique scheme, additive can form space steric effect, prevents the nano-Ag particles reunion together, thereby Nano Silver can be uniformly distributed in the deionized water.
In the technique scheme, the oxidable part Nano Silver of hydrogen peroxide solution makes it have the effect of dual antimycotic antiseptic.
Four, embodiment:
1, the equal particle diameter of making even is 20nm nano-silver powder 0.1g, methylcellulose 5g, and concentration is 30% hydrogen peroxide solution 0.1g, and deionized water 250g mixes, and adopting frequency is the ultrasonic echography 1 minute of 20khz, and after finishing, it is even to add the 744.8g deionized water and stirring again.
2, the equal particle diameter of making even is 40nm nano-silver powder 0.3g, methylcellulose 10g, and concentration is 30% hydrogen peroxide solution 0.1g, and deionized water 250g mixes, and adopting frequency is the ultrasonic echography 2 minutes of 28khz, and after finishing, it is even to add the 739.6g deionized water and stirring again.
3, the equal particle diameter of making even is 80nm nano-silver powder 0.5g, methylcellulose 7g, and concentration is 30% hydrogen peroxide solution 0.1g, and deionized water 250g mixes, and adopting frequency is the ultrasonic echography 3 minutes of 47khz, and after finishing, it is even to add the 742.4g deionized water and stirring again.
