Problems solved by technology

However, the permeability of the system has not been adjusted. Only relying on the adsorption properties of the iodine carrier—polyvinylpyrrolidone itself to approach the target surface cannot provide effective penetration properties, which affects the depth of the active ingredients into the target and the effectiveness of sterilization.
[0007] The invention patent with application number 00812978.9 ("Method for producing polyvinylpyrrolidone-iodine with aqueous solution") added formic acid, oxalic acid and its salts, esters, amides and other compounds as stabilizers, and the stability of the system was improved; and The invention patent with application number 99114144 is the same, the permeability of the system has not changed much, and the permeability of the system cannot meet the higher requirements, and high temperature (such as 70-110°C) is required for preparation, and the preparation method is complicated
[0008] The additives used in these invention patents are relatively simple and contain benzene derivatives, which have a bad impact on the natural environment

example 1

[0015] Example 1: Weigh 4.0 grams of PVP and dissolve it in 60ml of deionized water; when it is completely dissolved, add 15ml of potassium iodide solution of iodine and apply ultrasonic wave for 10 minutes; add 0.15 grams of citric acid and mix well; add 0.15 grams of SDS and mix well Add peracetic acid so that the quality of peracetic acid it contains is 0.012 grams; add deionized water to a volume of 100ml.

example 2

[0016] Example 2: Weigh 4.9 grams of PVP and dissolve it in 60ml of deionized water; when it is completely dissolved, add a solution of iodine and potassium iodide and apply ultrasonic waves for 10 minutes; add 0.15 grams of citric acid and mix well; add 0.15 grams of SDS and mix well Add peracetic acid so that the quality of peracetic acid it contains is 0.012 grams; add deionized water to a volume of 100ml.

example 3

[0017] Example 3: Weigh 5.4 grams of PVP and dissolve it in 60ml of deionized water; when it is completely dissolved, add a solution of iodine and potassium iodide and apply ultrasonic waves for 10 minutes; add 0.15 grams of citric acid and mix well; add 0.15 grams of SDS and mix well Add peracetic acid so that the quality of the peracetic acid it contains is 0.008 grams; add deionized water to a volume of 100ml.

Abstract

The present invention relates to one kind of efficient composite iodine disinfectant with powerful permeability and its compounding process. The disinfectant consists of mixture of PVP aqua and potassium iodide solution of iodine in certain proportion, synergist, stabilizer and deionized water for diluting to certain concentration. Owing to iodine carrier as main component, the synergist and the stabilizer to regulate the property of the system, the disinfectant has the advantages similar to that of PVP-I and the features of high permeability, high stability, less iodine color residue, high bactericidal effect and wide use range. The present invention may be disintegrated naturally and is environment friendly. The present invention may be used in effective disinfection of air in ward, operation room, hotel, waiting room in station, household and other places, the disinfection of medical equipment, and the pre-operation disinfection of skin, mucous membrane, etc.

Description

technical field [0001] The invention relates to a compound iodine disinfectant with strong permeability and high efficiency and a preparation method thereof. Background technique [0002] Polyvinylpyrrolidone is a nonionic surfactant that can form a complex with iodine. This complex has the functions of killing pathogenic bacteria, bacteria, fungi, etc., and its use is increasing day by day. [0003] The complex is usually obtained by mixing polyvinylpyrrolidone in solid or solution form with iodine or iodine compounds. The complexes prepared by these simple methods usually have good stability because the active ingredient-elemental iodine is relatively active and volatile; because no synergists, activators and other additives are added, the permeability of the system is not good. Good, and it is easy to color after spraying on the surface of the object, forming yellow stains. [0004] Application number is 91106026.X's invention patent ("The production method of quick-act...
