Description

Technical Field

[0001] The invention belongs to the technical field of animal husbandry, and in particular relates to a method for preparing a special cowshed disinfectant for a dairy farm. Background Art

[0002] Cowshed disinfectant is a liquid specially used for disinfecting and reducing inflammation in cattle sheds, livestock sheds, poultry houses, animal slaughterhouses and other breeding sites and equipment. Cowshed disinfectant can effectively kill various bacteria, viruses, fungi and other pathogens, eliminate the odors produced by drinking water, feed, sputum, feces, etc., greatly improve the cleanliness and hygiene of cattle sheds and other breeding sites and equipment, and reduce the risk of animals being infected with various diseases.

[0003] At present, various cattle shed disinfection products on the market have many defects and shortcomings: quicklime and other alkaline disinfectants have a high disinfection effect, but they are irritating and corrosive, which may damage the respiratory mucosa and cause stress to cattle, and are not suitable for use; oxidant, halogen, phenol and other disinfectants are easily affected by temperature, light, evaporation and other conditions and become ineffective, and their disinfection power is greatly affected by dirt; although phenol can effectively kill bacteria, it is toxic and corrosive, may pollute the environment, and is expensive; other types of disinfection products also have similar problems. The present invention can not only solve the above-mentioned defects, but also has a broad spectrum of sterilization, is fast and lasting, and is an important guarantee for ensuring the safe production of breeding enterprises. Summary of the invention

[0004] In order to solve the above problems existing in cowshed disinfection, the present invention discloses a cowshed disinfectant for dairy farms which can quickly kill bacteria on the surface of cowshed and equipment and a preparation method thereof, and is widely used in dairy farms.

[0005] To achieve the above object, the technical solution of the present invention is as follows:

[0006] The present invention provides a method for preparing a special cowshed disinfectant for a dairy farm, comprising the following steps:

[0007] S01, add excess ammonia water to the zinc lactate solution, heat to 30°C-50°C, stir for 1.5-3.5h, slowly add a mixture of ethanol and ethylene glycol, continue stirring for 1-3h, cool and filter to obtain a precursor;

[0008] S02. Add deionized water, dispersant, and a mixture of tartaric acid and lactic acid to the precursor, adjust the pH value, stir for 0.5-2.5h at 20-30°C, adjust the pH to 6-8, and prepare a cowshed disinfectant.

[0009] Furthermore, in step S01, the mass ratio of zinc lactate to ammonia water in the zinc lactate solution is 1:5-20.

[0010] Furthermore, in step S01, the mass ratio of zinc lactate to ethanol and ethylene glycol in the zinc lactate solution is 1:10-100:3-30.

[0011] Furthermore, the concentration of the zinc lactate solution is 5000-10000 ppm.

[0012] Furthermore, the mass percentage concentration of the ammonia water is 20%.

[0013] Furthermore, in step S02, the mass ratio of the precursor to deionized water is 1:100-1000.

[0014] Furthermore, in step S02, the mass ratio of the precursor to the dispersant is 1:1-10.

[0015] Furthermore, in step S02, the mass ratio of tartaric acid to lactic acid is 1:3.

[0016] Furthermore, in step S02, the mass ratio of the precursor to lactic acid is 1:0.001-0.01.

[0017] Furthermore, in step S02, the dispersant is one or more of sodium polycarboxylate, sodium polycarboxylate salt, ammonium polyacrylate, and polyethylene glycol 200.

[0018] The beneficial effects of the present invention are:

[0019] In step S01 of the present invention, the addition of excess ammonia water, heating to 30°C-50°C, and stirring for 1.5-3.5h can generate a substance with a multi-nuclear coordination structure, making the original zinc lactate structure more irregular, and forming a sharper acute angle, so that the bactericidal effect is more significant, not only has a good killing effect on Staphylococcus aureus, Candida albicans, and Escherichia coli, but also has a significant killing rate on Escherichia coli, and the effect is more significant in the air field and the air simulation field. The addition of ethylene glycol and ethanol can promote the precipitation of precursors, play a role in solid-liquid separation and improve the yield.

[0020] In step S02 of the present invention, a mixture of tartaric acid and lactic acid is added to the precursor solution to adjust the pH. The addition of a dispersant can make the entire system more compatible and more stable. The addition of deionized water plays a role in dissolving, dispersing and adjusting the content of the active ingredients in the product.

[0021] The material selection of the invention is green and environmentally friendly, non-toxic and non-irritating, and it is an environmentally friendly special disinfectant for cattle sheds; it is not affected by external conditions such as temperature, and has rapid sterilization and a broad spectrum; the product system of the invention is uniform and stable, has good water solubility, and a large dilution multiple; it improves the health of dairy farms and provides a healthy environment for the production of dairy farms.
