Embodiment 1

[0023] This embodiment provides a silver ion antibacterial liquid containing a silver ion-amino group ligand compound and a preparation method thereof.

[0024] The silver ion antibacterial liquid: its solvent is water, and its solute is silver oxide and ethylenediamine; wherein, the molar concentration of silver ions is about 0.1mol / L, and the molar concentration of amino groups is about 0.3mol.

[0025] The preparation method is as follows: take 23.2g of silver oxide (about 0.1mol of silver ion) and 9g of ethylenediamine (about 0.3mol of amino group), add water to 1000ml, stir at room temperature for 30min, and obtain the compound containing silver ion-amino group. Silver ion antibacterial liquid of body compound. Use Shanghai Lunjie Electromechanical Instrument Co., Ltd. NDJ-5S digital viscometer to measure the viscosity, and the viscosity is 98mPas.

Embodiment 2

[0027] This embodiment is a modification of Embodiment 1, and the only changes are: the molar concentration of silver ions is about 0.1 mol / L, and the molar concentration of amino groups is about 0.5 mol.

Embodiment 3

[0029] This embodiment provides a silver ion antibacterial gel and a preparation method thereof.

[0030] Described silver ion antibacterial gel: comprise silver ion antibacterial liquid described in embodiment 1 and gelatin (edible glue), add the weight of edible glue in the described silver ion antibacterial liquid of every liter is 100g, pH9, viscosity is 1100mPas .

[0031] The preparation method of described silver ion antibacterial gel: get the silver ion antibacterial liquid 100ml of embodiment 1, add gelatin 10g, heat and stir for 30min, dissolve gelatin, add sodium hydroxide to adjust pH value to be 9, obtain silver ion antibacterial gel. Use Shanghai Lunjie Electromechanical Instrument Co., Ltd. NDJ-5S digital viscometer to measure the viscosity, and the viscosity is 1100mPas.

Abstract

The invention discloses silver ion antibacterial liquid, silver ion antibacterial gel and a preparation method thereof. According to the silver ion antibacterial liquid, a solvent is water, solute is silver oxide and ethanediamine, molar concentration of silver ions is 0.05-0.5 mol / L, and molar concentration of an amino group is greater than that of the silver ions; the silver ion antibacterial gel comprises a mixture of the silver ion antibacterial liquid and edible glue, and an acid and alkaline regulator; weight of the edible glue added into each liter of the silver ion antibacterial liquid is greater than sum of weight of solute silver oxide and ethanediamine in the silver ion antibacterial liquid; and dose of the acid and alkaline regulator is based on regulating the pH value of the mixture to be basic. Compared with the prior art, the silver ion antibacterial liquid can ensure that viscosity meets practical needs, and is good in antibacterial effect. The silver ion antibacterial gel provided by the invention does not change color to affect the appearance even directly irradiated by hard light, and has stable and long-acting antibacterial effect.

Description

technical field [0001] The invention relates to the technical field of silver ion ligand compounds, in particular to a silver ion antibacterial liquid, a silver ion antibacterial gel and a preparation method thereof. Background technique [0002] High-efficiency sterilization and antibacterial products often contain silver ions and silver compounds, such as silver ion gels, silver ion dressings, silver ion antibacterial socks, etc. These silver ion products form black silver precipitates due to the reduction of silver ions under ultraviolet radiation. It only affects the appearance, but also affects the bactericidal and antibacterial effect, and the raw material silver ion used in these products has a very low viscosity. Adding it to liquids such as paints will cause the viscosity of the paint to decrease, making it difficult to coat, and it is necessary to add thickeners, etc. The cost increases, and many thickeners themselves contain toxic substances that are harmful to th...
