Embodiment 1

[0027] A kind of nanometer photocatalyst disinfectant, its component is calculated as:

[0028] Nano titanium dioxide photocatalyst powder 1~10%;

[0029] Ethanol 1~20%;

[0030] Water 70~98%;

[0031] Wherein, the particle size of the nano-titanium dioxide photocatalyst powder is 1-100 nm, preferably 1-20 nm.

[0032] The nano-titanium dioxide photocatalyst powder can be a visible light-type nano-titanium dioxide photocatalyst powder, which works under the following visible light conditions: light or natural light or sunlight; Work.

[0033] In this embodiment, 1% of ultraviolet-type nano-titanium dioxide photocatalyst powder (with a particle size of 1 nm), 1% of ethanol, and 98% of water are selected in terms of mass percentage.

[0034] The method for preparing the nano photocatalyst disinfectant solution according to the above-mentioned proportioning is:

[0035] ① Add the UV-type nano-titanium dioxide photocatalyst powder into the water, stir and mix it well to form ...

Embodiment 2

[0038] In terms of mass percentage, 5% of visible light-type nano-titanium dioxide photocatalyst powder (particle size is 7nm); 10% of ethanol; and 85% of water are selected.

[0039] The method for preparing the nano photocatalyst disinfectant solution according to the above-mentioned proportioning is:

[0040] ①Add visible light nano-titanium dioxide photocatalyst powder into water, stir and mix well to form a uniform visible light nano-titanium dioxide photocatalyst suspension.

[0041] ② Add ethanol to the visible light-type nano-titanium dioxide photocatalyst suspension, and stir well to become a nano-photocontact coal disinfectant.

Embodiment 3

[0043] In terms of mass percentage, 8% of visible light-type nano-titanium dioxide photocatalyst powder (particle size: 20nm); 15% of ethanol; and 77% of water are selected.

[0044] The preparation method of nanometer photocatalyst disinfectant is identical with embodiment 2.

Abstract

The invention relates to nano-photocatalyst disinfectant, which is prepared from the following components by mass percent: 1-10% of nano titanium dioxide photocatalyst powder, 1-20% of ethanol and 70-98% of water. A technology for preparing the nano-photocatalyst disinfectant comprises the following steps: (1) adding the nano titanium dioxide photocatalyst powder into water according to the proportion, and fully stirring and mixing to obtain uniform nano titanium dioxide photocatalyst suspension; (2) adding the ethanol into the nano titanium dioxide photocatalyst suspension, and fully and evenly stirring to obtain the nano-photocatalyst disinfectant. The effective components in the nano-photocatalyst disinfectant can fully adhere to the skin surfaces of patients and can disinfect and sterilize in a lasting way, and has the characteristics of being non-toxic, free from drug resistance, long-acting, broad-spectrum, and the like; furthermore, the nano-photocatalyst disinfectant is clear in color, convenient to observe and easy to use. The nano-photocatalyst disinfectant has an obvious curative effect for skin diseases such as beriberi, bromhidrosis and skin tinea which are caused by fungi and bacteria, and has an obvious healing promoting effect when being used for disinfecting wound.

Description

technical field [0001] The invention relates to the technical field of disinfectant, in particular to a nano photocatalyst disinfectant and a preparation method thereof. Background technique [0002] Sterilization and disinfection are inseparable from sterilizing and disinfecting drugs. In medicine, any chemical substance that quickly kills pathogenic microorganisms outside the body is called a disinfectant. Traditional chemical disinfectants are used in medical environment, skin, and wound disinfection. Unlike antibiotics, they have no obvious selective effect on pathogens and human tissues, so they are also highly toxic to the human body. When using traditional chemical disinfectants to sterilize and disinfect, they must be selected according to the characteristics and needs of various chemical substances, and there are certain toxicity and drug resistance problems, and there is no persistence. Contents of the invention [0003] The object of the present invention is to...
