Problems solved by technology

However, this method contains a large amount of ethanol, and the volatilization of ethanol will take away the heat on the surface of the nipple, causing the skin surface temperature to be lower; in addition, this method also does not add a film-forming agent, resulting in poor protection in winter

Abstract

The invention discloses a dairy cow nipple antifreezing disinfector. The disinfector comprises the following ingredients in part by weight: 3-6 parts of polymer film-forming agent, 50-60 parts of water, 1-2 parts of organic acid, 0.1-1 parts of thickener, 1-10 parts of skin-friendly agent, 20-60 parts of antifreezing agent, 0.05-0.5 parts of potassium iodate, and 0.1-1 parts of potassium iodite, wherein the polymer film-forming agent comprises the following ingredients in part by weight: 40-60 parts of water, 5-15 parts of PVP (polyvinyl pyrrolidone), 5-15 parts of N-methylpyrrolidone, and 20-40 parts of waterborne polyurethane emulsion. The dairy cow nipple antifreezing disinfector can form a layer of dense membrane on the dairy cow nipple to protect the dairy cow nipple from freezing and invasion of bacteria, and the formed protecting membrane is easy to wash away. In the meantime, the invention further discloses a preparation method of the disinfector. The preparation method is simple and safe to operate, and easy for industrial production.

Description

technical field [0001] The invention relates to a disinfectant and a preparation method thereof, in particular to a disinfectant for preventing freezing of cow teats and a preparation method thereof. Background technique [0002] In the dairy farming industry, dairy cow mastitis is known as the three major diseases in the dairy farming industry, and it is one of the main reasons for the loss of dairy farmers. Disinfectants are generally required to disinfect the teats before and after each milking of cows to prevent and control the occurrence of mastitis in cows. However, in winter in northern China, due to the cold climate, windy and low humidity, the surface of the nipple skin is often very dry, chapped, and even frostbitten and necrotic; Disinfection, because its water content exceeds 90%, often easily causes the teats to freeze and frostbite the teats, so that the cows are eliminated in advance, and often cause large economic losses to farmers or enterprises.
