Description
Technical Field
The invention relates to the technical field of disinfectants, in particular to an efficient and safe oxone compound disinfectant and a preparation method thereof.
Background
With the development of the breeding technology, the scale of the breeding industry is continuously enlarged, the breeding industry is rapidly and stably developed, and great economic benefits are brought to the society. In order to ensure the health of livestock and poultry, the poultry house must be disinfected regularly. The potassium hydrogen persulfate compound salt is a novel oxidation disinfectant and is widely applied to the fields of water quality treatment, livestock and poultry breeding, food medical treatment and the like.
At present, the existing oxone complex salt disinfectant is generally composed of oxone, sodium chloride, pigment and the like. The sterilization mechanism is as follows: the oxidation releases hypochlorous acid which is decomposed into nascent oxygen and free chlorine, and the sterilization effect is achieved through oxidation. However, such products have some disadvantages in use, such as: when in use, chlorine is released, and the chlorine has strong oxidability and has a corrosion effect on metal equipment in a farm; the content of the sterilization active ingredients of the disinfectant is indicated by adding the pigment, but the pigment is easily oxidized by chlorine and oxygen to be colorless, and the pigment cannot play an indicating role; in addition, chlorine generated in the product is easy to dissociate and volatilize, the disinfection effect is correspondingly weakened, and the product stability is poor.
Therefore, there is a need to develop a disinfectant product that is highly effective, less corrosive, and stable.
Disclosure of Invention
Therefore, in order to solve the above problems, it is necessary to provide an efficient and safe oxone compound disinfectant, which not only has a good disinfection effect, but also can reduce the corrosivity to metal equipment.
The high-efficiency safe potassium hydrogen persulfate composite disinfectant comprises the following raw materials in parts by weight:
the potassium hydrogen persulfate composite disinfectant does not use chlorine salt, thereby avoiding the corrosion effect of chlorine release of the chlorine-containing disinfectant on metal equipment and the interference on pigment components. After repeated research and study, the inventor finds that the bromine salt can effectively replace chlorine salt and also has a stronger disinfection effect, and the action mechanism is as follows: the hypobromous acid is released through oxidation, the hypobromous acid is decomposed to generate active oxygen and free bromine, the sterilization effect of the free bromine is better than that of free chlorine, and the oxidation of the hypobromous is lower than that of the hypobromous, so that the hypobromous acid is less corrosive to metals and higher in safety. In addition, after the disinfectant is dissolved in water, bromine is released to enable the solution to be displayed in reddish brown, when the reddish brown is faded, the content of the disinfection component in the disinfectant is reduced, the content of the disinfection component in the product can be judged according to the color of the product, no pigment is required to be additionally added for indication, and the preparation cost of the product is reduced.
In one embodiment, the bromine salt is selected from: one or more of sodium bromide, potassium bromide, calcium bromide, lithium bromide, magnesium bromide, ammonium bromide, aluminum bromide and manganese bromide.
In one embodiment, the hexametaphosphate salt is selected from sodium hexametaphosphate.
In one embodiment, the synergist is selected from: one or more than two of calcium percarbonate, sodium percarbonate and calcium peroxide. The peroxide synergist can improve the oxidation effect of the product.
In one embodiment, the surfactant is selected from: one or more of sodium dodecyl sulfate, sodium dodecyl sulfate and sodium dodecyl benzene sulfonate.
In one embodiment, the water-soluble paint further comprises 1-3 parts of a pH regulator.
In one embodiment, the pH adjusting agent is selected from: one of sodium hydroxide and potassium hydroxide.
In one embodiment, the pH value of the potassium hydrogen persulfate composite disinfectant is 2-9.
After the potassium hydrogen persulfate composite disinfectant added with sodium chloride in the prior art is dissolved in water, a large amount of acid is usually added to adjust the pH value of the disinfectant to be 2-5, a large amount of hypochlorous acid components can be generated in a system under a strong acid condition, no hypochlorous acid is generated under a neutral or alkaline condition, only free chlorine exists, the free chlorine is volatile, and the sterilization effect is weakened. After the disinfectant is prepared into the disinfectant, free bromine has good stability and a good sterilization effect in a neutral or alkaline environment. Therefore, when the disinfectant is used, the pH value is kept in a large range (pH is 2-9), so that a good sterilization effect can be ensured, and the disinfectant has good stability, and the characteristic is favorable for expanding the application range of products.
The invention also provides a preparation method of the efficient safe potassium hydrogen persulfate composite disinfectant, which comprises the following steps: pulverizing the above materials, sieving, and mixing.
The preparation method is simple and easy to operate, and is beneficial to reducing the manufacturing cost of the product.
The invention also provides a use method of the high-efficiency safe potassium hydrogen persulfate composite disinfectant, which comprises the following steps: mixing the solid disinfectant and water according to the weight ratio of (0.05-5): 100, dissolving the solid to obtain a disinfectant, and spraying the disinfectant on an area to be disinfected. The concentration of the disinfectant can be adjusted according to the requirement.
The invention also provides a liquid disinfectant, which comprises the following raw materials in parts by weight:
0.05 to 5 parts of the potassium hydrogen persulfate composite disinfectant,
100 parts of water.
In one embodiment, the liquid disinfectant has a pH value of 2-9. The liquid disinfectant disclosed by the invention can keep good disinfection performance at a pH value of 2-9, and can keep good stability.
Compared with the prior art, the invention has the following beneficial effects:
compared with the existing chlorine-containing disinfectant, the potassium hydrogen persulfate composite disinfectant disclosed by the invention has the following advantages: 1) the sterilization effect is better and more efficient; 2) the corrosion to metal is less, and the safety is higher; 3) the volatility is lower, and the product stability is better; 4) the reaction progress can be indicated by the self color change (gradual fading of reddish brown), and no indicator needs to be added; 5) Bromine-containing disinfectants decay faster in the environment than chlorine-containing disinfectants, and are less harmful to the environment. The disinfectant is particularly suitable for disinfecting livestock industry equipment.
