Photocatalytic sterilizing and mosquito repelling agent loaded with black titanium dioxide and preparation method thereof

Abstract

The invention discloses a photocatalytic sterilizing and mosquito repelling agent loaded with black titanium dioxide and a preparation method thereof. The sterilizing and mosquito repelling agent comprises the following raw material in parts by weight: 4-8 parts of black titanium dioxide, 15-20 parts of Chinese mugwort extract solution, 9-15 parts of perilla leaf extract solution, 13-17 parts of peppermint essential oil, 7-15 parts of aloe essential oil, 8-12 parts of essential oil emulsifiers and 25-32 parts of food grade ethanol. The photocatalytic sterilizing and mosquito repelling agent loaded with black TiO2(subscript) disclosed by the invention is simple in raw materials and preparation processes and low in cost; the high-efficiency and environment-friendly photocatalytic sterilizingand mosquito repelling agent is environment-friendly and healthy without adding any toxic chemicals, and has characteristics of strong mosquito repelling durability, excellent sterilizing performance, etc. Moreover, the preparation method of the invention is simple and easy to operate, and is not only suitable for laboratory preparation, but also suitable for large-scale production.

Description

technical field

[0001] The invention relates to the field of mosquito repellents, in particular to a photocatalytic bactericidal mosquito repellent loaded with black titanium dioxide and a preparation method thereof. Background technique

[0002] Every summer and autumn, mosquitoes are rampant, and people are often bitten by mosquitoes, which seriously affects people's normal life, work, study and rest. The route of transmission poses a serious threat to people's health. At present, the main component of commercially available mosquito repellent is a mixture of DEET and alcohol or an alcohol solution containing Chinese herbal medicine extracts. As long as it is applied to the surface of human skin, it can have the effect of repelling mosquitoes. Existing mosquito repellents have Mosquitoes have a short effective time, and some ingredients are slightly toxic, which may endanger human health if used for a long time.

Examples

Embodiment 1

[0027] A photocatalytic bactericidal mosquito repellent loaded with black titanium dioxide of the present embodiment includes the following raw materials in parts by mass: 4 g of black titanium dioxide, 15 g of wormwood extract, 9 g of perilla leaf extract, 13 g of peppermint essential oil, 7 g of aloe vera essential oil, Essential oil emulsifier 8g, food grade ethanol 25g. In this embodiment, the solid content of the extract of wormwood is 3%, and the solid content of the perilla leaf extract is 8%. In this embodiment, the essential oil emulsifier is monoglyceride, and the essential oil emulsifier is refreshing and comfortable when sprayed on the body. All the aforementioned ingredients and raw materials can be purchased directly from the market.

[0028] Among them, the black TiO 2 It is at the nanometer level with a particle size of 5-10 nm. The present invention uses black titanium dioxide instead of conventional white titanium dioxide powder, mainly because white TiO ...
