Abstract
The invention discloses a bactericidal agent and a manufacturing method thereof, belonging to the biochemistry field, in particular to a bactericidal agent and a manufacturing method thereof. The invention provides a bactericidal agent with simple technology, favorable sterilizing effect, safety and no toxicity and provides the manufacturing method thereof. The invention adopts the following technical scheme that the bactericidal agent is neutral aqueous solution which contains nanometer metal, photochemical catalyst, dispersing agent and water, and the pH value of the neutral aqueous solution is 6-7. The bactericidal agent is characterized in that the components are as follows in percentage by weight: 0.10-2.5% of nanometer metal, 1.0-25.0% of photochemical catalyst, 0.50-14.0% of dispersing agent and 80-98% of water; and the dispersing agent can be one or a plurality of glycol, sodium hexametaphosphate, sodium silicate and alcohol. The nanometer metal is single-element silver of 5-60 nm, the photochemical catalyst contains at least two of titanium dioxide of 10-30 nm, zinc oxide of 5-30 nm and magnesium oxide of 2-30 nm. The manufacturing method of the invention is characterized in mixing three raw materials at ratio, adding into water to be evenly stirred and pulped, and coating on a paper substrate.
Description
Technical field
The invention belongs to biochemical field, relate in particular to a kind of bactericidal agent and preparation method thereof.
Background technology
" sterilization " promptly is all hygienic articles and virus all will be killed, to reach aseptic purpose.In environmental pollution serious day by day today; crisis-ridden in our living environment, exist invisible pathogenic bacteria of many naked eyes and virus, the health that they invade us by respiratory tract, digestive system or skin contact; cause various diseases, even also can threaten our life.Add up according to hygiene department, reach more than 30 ten thousand people because of gastrointestinal disease death person every year, do not cause because be not careful in one's diet health mostly, and the regular incidence more than 80 percent, for example: flu, dysentery, skin disease, venereal disease, gynaecological disease, tuberculosis, hepatitis B or the like, also all be because pathogenic bacteria, virus intrusion and other condition concurrent due to.The effective method that prevents these diseases is exactly the disinfecting work of strengthening daily life environment, diet and human body self aspect.Safe in utilization, effective method is done omnibearing sterilization to the daily life environment, can not only improve our quality of life, more can prevent disease, ensure healthy.
The bactericide of Xiao Shouing in the market, major part all has certain toxicity, and its residue is harmful to health.Adopt in practice to be coated with to be prevented to preserve fruits and vegetables by multiple means such as fresh-keeping method, chemical storage method, biological antiseptic methods and infected by mould and rot, or suppress fruits and vegetables metabolism, prevent aging, prolong storage ﹠ fresh-keeping period.From choice of preservatives, what China's application in the past was maximum is topsin and two kinds of bactericide of carbendazim, its outstanding feature is efficient and systemic action, major defect are arranged is that systemic action then causes the residual quantity height owing to the resistance fungus strain occurs comparatively fast causing drug effect to reduce.This preservative is if be used for thin skin fruits such as apple, pears, and residual dense agricultural chemicals flavor then becomes its significant disadvantages.
Summary of the invention
Purpose of the present invention just is to overcome the prior art above shortcomings, and a kind of technology is simple, sterilization effect good, the bactericidal agent of safety non-toxic evil and provide, and preparation method thereof.
To achieve these goals, the present invention adopts following technical scheme, and the present invention is that to contain the pH value of nano metal, photochemical catalyst, dispersant and water be 6～7 neutral aqueous solution, and it is characterized in that: above-mentioned each composition is proportioning as following weight percent:
Nano metal 0.10～2.5 photochemical catalyst 1.0～25.0
Dispersant 0.50～14.0 water 80～98;
Described dispersant can be one or more in ethylene glycol, calgon, sodium silicate, the ethanol, and wherein ethylene glycol can use separately, and other several need use jointly.
Described nano metal is 5～60nm simple substance silver, photochemical catalyst comprises that supported titanium dioxide is the visible light catalyst or the ultraviolet light catalyst of matrix with Metaporous silicon dioxide material MCM-41 or AIMCM-41, can be at least two kinds in 10～30nm titanium dioxide, 5～30nm zinc oxide, the 2～30nm magnesia.
A kind of preserving fruit and vegetable utilizing bactericidal agent preparation method is planted raw material with above-mentioned first three and is mixed in proportion, adds in the entry to stir, and making beating is coated on the paper substrates then.
Beneficial effect of the present invention
1, safety non-toxic evil: the present invention is used for preserving fruit and vegetable utilizing to the combination of the sterilizing function of light-catalysed decomposition ethene function and nanometer simple substance silver, do not contain preservative, not only can kill mould, but also can killing bacteria, because this product contains inorganic fungicide, can not make fruit produce peculiar smell, except that sterilization, decompose the function of ethene in addition, compare with existing tin foil, composition and effect are all different, and not chloride;
2, sterilization effect is good: the present invention has adopted high efficiency photocatalyst, and higher activity is also arranged under visible light, even thereby need not ultraviolet ray also can sterilization;
3, technology is simple: the present invention does not need big equipment investment, using method is easy, can be used as antistaling coating, the surface that directly smear, method such as sprinkling imposes on fruits and vegetables, air-dry back forms the very thin transparent coating of one deck, in order to strengthen the protective action of fruits and vegetables cortex; Suitably stop up aperture portion, suppress respiration, reduce nutrient consumption; Suppress moisture and distribute, prevent the shrinkage wilting; Suppress microorganism and invade, prevent putrid and deteriorated.Also the powdery antistaling agent can be packed in the ventilative good cloth bag, seal standby.
