preparation example Construction

[0040] The present invention provides a kind of preparation method of slow-release drinking water disinfectant, comprising:

[0041] S101: mixing potassium hydrogen persulfate, crosslinking agent and auxiliary agent according to the formula to obtain a mixture;

[0042] Wherein, the formula includes 70-90 parts of potassium hydrogen persulfate in parts by weight; 6-13 parts of auxiliary agent; 2-5 parts of crosslinking agent;

[0043] Wherein, auxiliary agent comprises anionic surfactant and filler;

[0044] The anionic surfactant is selected from one or a combination of alkyl sodium sulfate, sodium dodecylbenzenesulfonate, sodium alkylsulfonate, and oleoyl amino acid sodium; the anionic surfactant can reduce the surface tension of water and contribute to The disinfectant is evenly dispersed in the water to be disinfected to improve the disinfection effect. Preferably, the anionic surfactant is selected sodium dodecylbenzene sulfonate, and its addition weight part is 1-3 par...

Embodiment 1

[0067] formula:

[0068] 90 parts of potassium hydrogen persulfate, 5 parts of crosslinking agent, 2 parts of anionic surfactant, 5 parts of filler agent; 5 parts of emulsion;

[0069] Wherein, the cross-linking agent is selected from borax, the anionic surfactant is selected from sodium dodecylbenzenesulfonate, the filler is selected from sodium chloride; the latex solution is selected from polyvinyl alcohol solution with a concentration of 2%.

[0070] Preparation:

[0071] (1) Potassium hydrogen persulfate, crosslinking agent, filler, anionic surfactant are fully mixed;

[0072] (2) Add 20% alcohol of the mixture mass (the volume ratio of water to alcohol is 2:1), and carry out rotary granulation;

[0073] (3) Spray the latex in the turntable granulator, and turn the turntable to mix;

[0074] (4) The obtained material is placed in the air for 1.5h to make the surface gel solidify;

[0075] (5) Use a belt-type tunnel kiln dryer to dry at 80° C., stop drying after drying...

Embodiment 2

[0077] formula:

[0078] 80 parts of potassium hydrogen persulfate, 3 parts of crosslinking agent, 3 parts of anionic surfactant, 10 parts of filler; 4 parts of emulsion;

[0079] Among them, the cross-linking agent is selected glutaraldehyde, the anionic surfactant is selected sodium dodecylbenzenesulfonate, and the filler is selected sodium chloride; the latex liquid is selected from a chitosan solution with a concentration of 2%, and the chitosan is dissolved in acetic acid .

[0080] Preparation:

[0081] (1) Potassium hydrogen persulfate, crosslinking agent, filler, anionic surfactant are fully mixed;

[0082] (2) Add 25% alcohol (volume ratio of water to alcohol is 2:1) of the mixture mass, and carry out rotary granulation;

[0083] (3) Spray the latex in the turntable granulator, and turn the turntable to mix;

[0084] (4) The obtained material is placed in the air for 2 hours to make the surface gel solidify;

[0085] (5) Use a belt-type tunnel kiln dryer to dry a...

Abstract

The invention discloses a slow-release drinking water disinfectant and a preparation method thereof. The preparation method comprises the following steps: mixing potassium persulfate, a crosslinking agent and an auxiliary agent according to the formula; granulating; coating a latex liquid which can be crosslinked with a crosslinking agent; curing the surfaces of granules through gel polymerization; and drying to obtain the slow-release drinking water disinfectant. Correspondingly, the invention also discloses the slow-release drinking water disinfectant prepared by the method. The slow-releasedrinking water disinfectant reduces the frequency of repeated application, is economical and applicable as well as safe and effective, has controllable slow release rate and has extremely high promotion value.

Description

technical field [0001] The invention relates to a disinfectant, in particular to a slow-release drinking water disinfectant and a preparation method thereof. Background technique [0002] Poultry drinking water hygiene has an important impact on the health of livestock and poultry. However, the problem of drinking water for livestock and poultry has not been taken seriously, and there is no special disinfectant for drinking water for livestock and poultry on the market. However, once livestock and poultry drink water containing bacteria, it will often cause gastrointestinal diseases or parasitic diseases of livestock and poultry. Even severe cases can cause the death of animals. [0003] At present, the most commonly used method for disinfection of drinking water in farms is chemical disinfection, that is, chemical disinfectants are used for disinfection. Chemical disinfectant disinfection has many advantages, such as strong ability to kill pathogenic microorganisms in wat...
