preparation example Construction

[0038] The preparation method of the self-thickening type high-content iodophor solution for aquatic products of the present invention comprises the following steps:

[0039] Step 1. Prepare the raw materials according to the above formula and set aside;

[0040] Step 2. Add alcohol ether nonionic surfactant, amide type surfactant and iodine to the reaction kettle, control the reaction temperature at 50-60°C, stir for 2-3 hours, and control the stirring speed at 50-100r / min, if it is too high The stirring speed is easy to generate bubbles, which is not conducive to the complexation reaction;

[0041]Step 3, add potassium iodide and potassium iodate into a small amount of water, add to the reaction kettle after dissolving completely, and react for 1 to 2 hours;

[0042] Step 4. Add the auxiliary agent to the remaining water, after dissolving, add it to the reaction kettle, turn off the heating device, and continue the reaction for 30-60 minutes to obtain a self-thickening high...

Embodiment 10

[0054] Stability experiment of embodiment 10 polyalcohol ether iodine dilution

[0055] High-content povidone-iodine solution cannot be directly used for disinfection. It needs to be diluted in actual use until the available iodine is between 0.5% and 1.0%. Therefore, whether the properties of the diluted solution meet the requirements is to examine its highest complexing ability. standard. In this embodiment, the above-mentioned embodiments 1-9 are diluted, and the solution state thereof is investigated. The results are shown in Table 4.

[0056] The solution state of the polyalcohol ether iodine dilution of table 4 embodiment 1-9

[0057]

[0058] As can be seen from Table 4, the iodophor solutions of Examples 1-4 have good stability after dilution, and maintain good stability after freezing experiments. And the povidone iodine solution of embodiment 5-9, along with the increase of available iodine content, the character of its diluent is more unstable, and the embodim...

Embodiment 11

[0060] The consistency change experiment of embodiment 11 povidone iodine solution dilution

[0061] 1. The consistency change experiment of the povidone iodine solution dilution of embodiment 1-6

[0062] There is a problem in the use of existing povidone iodine preparations that the consistency of the solution after dilution is low, which brings great inconvenience in fields such as aquatic products and dairy cow disinfection that require the consistency of the solution, and it is necessary to add a thickening compound Thickening is carried out separately, and the process is cumbersome and troublesome; at the same time, the thickener needs to add special thickener dissolving equipment, which greatly increases the cost of the manufacturer. Apps make a lot of sense. This embodiment dilutes the above-mentioned embodiments 1-6, and investigates the changes in the consistency of the povidone iodine solution stock solution and its dilution. The results are shown in Table 5.

Abstract

The invention discloses a self-thickening high-content iodophor solution for aquatic products, which is prepared from the following raw materials in weight percent: 40%-50% of polyalcohol ether nonionic surfactant; 10% of amide type surfactant ~25%; Iodine 10%~13%; Potassium iodide 1.0%~4.0%; Potassium iodate 0.1%~0.3%; Auxiliary 0.5%~1.0%; The balance is water. The invention also discloses the preparation method of the iodophor solution: adding alcohol ether nonionic surfactant, amide type surfactant and iodine into the reaction kettle, stirring at a reaction temperature of 50-60°C; adding dissolved potassium iodide , Potassium iodate, react for 1-2 hours; then add the dissolved additives, turn off the heating device, and react for 30-60 minutes. The obtained self-thickening high-content iodophor solution for aquatic products can increase the effective iodine content, and the product has self-thickening performance after dilution, and has good sterilization and disinfection effects.

Description

technical field [0001] The invention belongs to the technical field of sterilization and disinfection of aquatic products, and in particular relates to a self-thickening high-content povidone iodine solution for aquatic products and a preparation method thereof. Background technique [0002] Aquaculture is one of the industries with a huge system in my country's animal husbandry. With the continuous improvement of the scale and intensification of aquaculture, the stocking density of aquaculture animals is increasing, the incidence of aquaculture animals is getting higher and higher, and the disease is more and more complicated, and some even reach the point where it is difficult to control, which seriously hinders healthy development of the aquaculture industry. It is an effective measure to improve the water environment and control aquatic animal diseases by using safe and efficient disinfectants to kill pathogens in water and on the surface of farmed animals, so as to cut...
