Embodiment 1
[0015] A slow-release broad-spectrum antibacterial agent, the material includes by weight: butyl chitosan 50%, medicinal iodine 10%, distilled water 30%, potassium iodate 5%, sodium carbonate-sodium bicarbonate buffer solution 5% %.
[0016] The preparation method of the above-mentioned slow-release broad-spectrum antibacterial agent is as follows: (1) take 1 part of medicinal iodine and 5 parts of butyl chitosan, mix fully and uniformly, grind until the diameter is 1.2-1.8 mm, and obtain brown-black powder; (2) Move it into a wide-mouth container, heat it with an oil bath at 96 degrees Celsius, and stir continuously for 18 hours until the wet starch test paper is placed in the mouth of the container for 30 seconds until the test paper does not show blue, indicating that the uncomplexed free iodine has been removed. (3) Add 3 parts of water to form an aqueous solution; (4) Add 0.5 parts of potassium iodate to the aqueous solution; (5) Add 0.5 parts of sodium carbonate-sodium b...
Embodiment 2
[0018] A slow-release broad-spectrum antibacterial agent, the material includes by weight: butyl chitosan 45%, medicinal iodine 10%, distilled water 35%, potassium iodate 5%, sodium carbonate-sodium bicarbonate buffer solution 5% %.
[0019] The preparation method of the above-mentioned slow-release broad-spectrum antibacterial agent is as follows: (1) take 1 part of medicinal iodine and 4.5 parts of butyl chitosan, mix them fully and uniformly, grind until the diameter is 1.2-1.8 mm, and obtain a brown-black powder; (2) Move it into a wide-mouth container, heat it with an oil bath at 96 degrees Celsius, and stir continuously for 18 hours until the wet starch test paper is placed in the mouth of the container for 30 seconds until the test paper does not show blue, indicating that the uncomplexed free iodine has been removed. (3) Add 3.5 parts of water to form an aqueous solution; (4) Add 0.5 parts of potassium iodate to the aqueous solution; (5) Add 0.5 parts of sodium carbona...
Embodiment 3
[0021] A kind of sustained-release broad-spectrum antibacterial agent, described material comprises by weight: butyl chitosan 40%, medicinal iodine 10%, distilled water 40%, potassium iodate 5%, sodium carbonate-sodium bicarbonate buffer solution 5%.
[0022] The preparation method of the above-mentioned slow-release broad-spectrum antibacterial agent is as follows: (1) take 1 part of medicinal iodine and 4 parts of butyl chitosan, mix them fully and uniformly, grind until the diameter is 1.2-1.8 mm, and obtain a brown-black powder; (2) Move it into a wide-mouth container, heat it with an oil bath at 96 degrees Celsius, and stir continuously for 18 hours until the wet starch test paper is placed in the mouth of the container for 30 seconds until the test paper does not show blue, indicating that the uncomplexed free iodine has been removed. (3) Add 4 parts of water to form an aqueous solution; (4) Add 0.5 parts of potassium iodate to the aqueous solution; (5) Add 0.5 parts of ...
