Embodiment 1

[0056] Take 50 grams of soluble starch (Starch), add it to 850 grams of water, stir, dissolve, heat up to 90°C for further dissolution, add water to a total of 900 grams, and prepare Starch aqueous solution. Take 10 grams of polyhexamethyleneguanidine hydrochloride (GP1), add it into 90 grams of water, stir and dissolve, and prepare an aqueous solution of guanidine-based polymer. 100 grams of the prepared guanidinium polymer aqueous solution are added to the prepared 900 grams of Starch aqueous solution, stirred, and mixed uniformly to obtain the Starch / GP1-1 composite disinfection mother liquor with a Starch concentration of 5.0% and a guanidinium salt polymer concentration of 1.0%. .

Embodiment 2

[0058] Take 50 grams of soluble starch (Starch), add it to 850 grams of water, stir, dissolve, heat up to 90°C for further dissolution, add water to a total of 900 grams, and prepare Starch aqueous solution. Take 5 grams of polyhexamethylene biguanide hydrochloride (GP2), add it into 95 grams of water, stir and dissolve, and prepare a guanidine-based polymer aqueous solution. 100 grams of the prepared guanidinium polymer aqueous solution are added to the prepared 900 grams of Starch aqueous solution, stirred, and mixed uniformly to obtain Starch / GP2-2 composite disinfection mother liquor with a Starch concentration of 5.0% and a guanidinium salt polymer concentration of 0.5%. .

Embodiment 3

[0060] Take 20 grams of soluble starch (Starch), add it to 880 grams of water, stir, dissolve, raise the temperature to 90°C for further dissolution, add water to a total of 900 grams, and obtain Starch aqueous solution. Take 1 gram of polyhexamethylene guanidine phosphate (GP3), add it into 99 grams of water, stir and dissolve to obtain an aqueous solution of guanidine-based polymer. 100 grams of the prepared guanidine-based polymer aqueous solution are added to the prepared 900 grams of Starch aqueous solution, stirred, and mixed uniformly to obtain a Starch / GP3-3 composite disinfection mother liquor with a Starch concentration of 2.0% and a guanidinium salt polymer concentration of 0.1%. .

Abstract

The invention belongs to the technical field of disinfectants, and relates to a safe and long-acting disinfection mother solution, which comprises a disinfectant, a water-soluble polymer and water, and the disinfectant is selected from one or more of guanidine salt polymers. After being diluted into a disinfectant, the disinfection mother liquor is coated or sprayed on the surface of an object toform an antimicrobial film. The disinfectant is enriched on the surface of the membrane and has a hydrogen bond association effect with the water-soluble polymer, so that a disinfection function is efficiently and permanently performed on the surface of an object at a very low concentration. The disinfection mother liquor disclosed by the invention has the characteristics of safety and greenness,can be used for efficiently disinfecting the surface of an object for a long time and has a good application prospect.

Description

technical field [0001] The invention belongs to the technical field of disinfectants, in particular to a safe and long-acting disinfectant mother solution. Background technique [0002] On the surface of objects in hospitals, public health places, office areas, etc., there are often some germs, and these germs may exist for a long time (see Table 1, Yang Huaming et al., "Modern Hospital Disinfection"). [0003] Table 1 The survival time of some bacteria on the surface of dry objects [0004] Bacteria survival time Bacteria survival time Acinetobacter 5 months Helicobacter pylori 1.5h Campylobacter jejuni 6d Listeria sp. several months Clostridium difficile spores 5 months Mycobacterium tuberculosis 4 months Pseudomonas aeruginosa 5 weeks Neisseria gonorrhoeae 3d diphtheria 6 months Proteus 24h Escherichia coli several months Salmonella typhi 4 weeks Enterococcus 4 months Salmonella typhimuri...
