Description
Technical field
The present invention relates to material chemistry technical field, be specifically related to the compound disinfectant of a kind of Nano Silver and polyhexamethylene guanide.
Background technology
Bactericide has organic bactericide and inorganic fungicide, and organic bactericide consumption is little, and germicidal efficiency is high, but Long-Time Service makes mushroom easily develop immunity to drugs, and the usage amount of bactericide needs to continue to increase, and finally acts on more and more less.Another weakness is that organic bactericide easily lost efficacy, and the drug effect phase is short.Inorganic fungicide dosage is large, and germicidal efficiency is low, and toxicity is large.But inorganic fungicide often duration of efficacy is long, do not develop immunity to drugs, present polyhexamethylene guanide is very effective environment-friendly type organic bactericide, and its toxicity is very low, human body is not damaged, but also there is the problem short with duration of efficacy that easily develop immunity to drugs in it.Silver is close human metalloproteinase, silver salt bactericide due to sterilizing rate high, lasting medicine and welcome, but silver salt is oxidative bactericide, improper use easily produces injury to human body.
Summary of the invention
Main purpose of the present invention is to provide compound disinfectant and the processing technology of a kind of Nano Silver and polyhexamethylene guanide, and germicidal efficiency is high, cost is low.
The technical solution adopted for the present invention to solve the technical problems is:
The compound disinfectant of a kind of Nano Silver and polyhexamethylene guanide, this compound disinfectant is by Nano Silver, polyhexamethylene guanide, dispersant, stabilizing agent, complexing agent and water composition, this compound disinfectant is the aqueous solution, the mass ratio of Nano Silver and polyhexamethylene guanide is (1: 100)-(1: 10000), Nano Silver and polyhexamethylene guanide gross mass account for 1% ~ 50% of total solution quality, dispersant accounts for 0.1% ~ 10% of total solution quality, stabilizing agent accounts for 0.1% ~ 10% of total solution quality, complexing agent accounts for 1% ~ 30% of total solution quality, its surplus of solution is water.
Preferably, the particle size range of Nano Silver is 1 nanometer-100 nanometer; Polyhexamethylene guanide is: the one or any several combinations according to arbitrary proportion in polyhexamethylene guanidine hydrochloride, polyhexamethylene phosphoguanidine or polyhexamethylene sulfuric acid guanidine.
Preferably, dispersant comprises cationic surfactant and neutral surface active agent, cationic surfactant is: eight alkyl bromination ammoniums, eight alkyl ammomium chlorides, ten alkyl bromination ammoniums, ten alkyl ammomium chlorides, dodecyl bromination ammonium, lauryl ammonium chloride, Tetra-n-decylammonium bromide, tetradecyl ammonium chloride, cetyl ammonium bromide, cetyl chloride ammonium, octadecyl bromination ammonium, octadecyl ammonium chloride, dodecyl dimethyl benzyl ammonium bromide, dodecyl benzyl dimethyl ammonium chloride, tetradecyl dimethyl benzyl ammonium, myristyl benzyl dimethyl ammonium chloride, cetyl dimethyl benzyl ammonium bromide, cetalkonium chloride, one or any several combinations according to arbitrary proportion in octadecyl dimethyl benzyl ammonium bromide or stearyl dimethyl benzyl ammonium chloride, neutral surface active agent comprises: the many ammonium salts of triethanolamine, diethanol amine, monoethanolamine, polyethylene, the one or any several combinations according to arbitrary proportion in polyoxyethylated alkyl alcohol, polyethenoxy alkylphenols, polyoxyethylated alkyl alcohol sulfuric ester sodium salt, OP (alkylphenol polyoxyethylene), tween or this Pan.

The present invention also provides the compound disinfectant processing technology of a kind of Nano Silver and polyhexamethylene guanide, at room temperature, get the various raw materials of the proportioning in technique scheme, polyhexamethylene guanide is dissolved in the water, then add dispersant, stabilizing agent, complexing agent, stir, add Nano Silver again after all dissolving, fully stir, Nano Silver is disperseed completely, filter, obtain the composite bactericidal agent solution of Nano Silver and polyhexamethylene guanide.
Implement technical scheme of the present invention, there is following beneficial effect: the compound disinfectant of Nano Silver provided by the invention and polyhexamethylene guanide, by Nano Silver and polyhexamethylene guanide compound, greatly enhance both germicidal efficiencies, and reduce cost, be convenient to popularize.Nano Silver and polyhexamethylene guanide compound disinfectant can use in medicine, daily life, also can treat domestic birds and animals disease of skin.
Pharmaceutically can be used as the skin disease such as beriberi, eczema external application liquid medicine, the eyedrops for the treatment of keratitis, sty can be made, also can be used as women's private parts washing liquid medicine.The skin disease that the fungal infection such as beriberi, eczema causes, belongs to refractory illness, and conventional medicament for the eyes has aureomycin, chloramphenicol, Natamycin, tobramycin, fluoquinolone now, and drug effect is low, and pesticide resistance is strong, and duration of efficacy is short.Women's private parts washing medicine has that clean you are cloudy, scorching clean, the potassium permanganate of woman etc., there is same problem.The skin disease medication that the fungal infection such as beriberi, eczema causes has compound thunder to lock pungent, the tincture of iodine, onychomycosis tincture, calamine, boric acid, triamcinolone, nitric acid Miconazole, neomycinsulphate, compound Triamcinolone Acetonide, Da Kening, benzoic acid etc., and these organic synthesis medicines not easily thoroughly eradicate fungi because duration of efficacy is short.Polyhexamethylene guanide is the large polymeric electrolyte of polycation, it large area can be adsorbed on skin surface and to live germ surface of cell membrane, Nano Silver complexing more enhances its bactericidal effect thereon, Nano Silver duration of efficacy is long, thoroughly can eradicate fungi, Nano Silver and polyhexamethylene guanide compound disinfectant are efficient, lasting, safe bactericide.
In daily life, in daily life, can thimerosal, desinfactant detergent, dishwashing liquid, fruit detergent with sterilizing be used as, swimming sterilizing agent.Although there is various bactericide, majority is oxidative bactericide, e.g., and liquid chlorine, potassium permanganate, hydrogen peroxide, ozone, chloramines, chlorine dioxide, Peracetic acid, 84 thimerosals, formalin, lysol.There is impact to environment during these conventional bactericide sterilizations, have residual hazard after sterilization, have harm to human body.When Nano Silver and polyhexamethylene guanide compound disinfectant use as mild as a dove, do not have residual hazard, duration of efficacy is long, is more satisfactory bactericide.
The frequent skin infection of domestic birds and animals is sick, needs often to carry out disinfection to poultry house.Common drug has bromogeramine (quaternary ammonium compound), lysol (methylphenol), domiphen (Domiphen bromide), Peracetic acid, sodium dichloro cyanurate.These medicines are all Small molecular, and duration of efficacy is short, and drug effect is low, have pollution to environment, have residual hazard.When Nano Silver and polyhexamethylene guanide compound disinfectant use as mild as a dove, do not have residual hazard, do not injure poultry, duration of efficacy is long, does not pollute environment, does not have residual hazard, is more satisfactory bactericide.
