Abstract

The invention discloses a graphene disinfectant and a preparation method thereof. The method comprises the following steps: 1, preparing a water-soluble graphene dispersion; 2, preparing a water-soluble graphene dispersion liquid; 3, adding a dispersing agent into the water-soluble graphene solution obtained in the step 2, and uniformly stirring; 4, continuously adding a surfactant into the solution, continuously stirring until the solution is uniform, and defoaming; and step 5, standing and cooling to room temperature, and filling into a container to obtain the graphene disinfectant. The invention also provides the graphene disinfectant prepared by the method; the main components adopted by the invention comprise water-soluble graphene, a food-grade dispersing agent, a food-grade surfactant and deionized water. The disinfectant has the characteristics of environmental protection, good sterilization effect, long antibacterial time, no pungent smell, low production cost and the like, and can be applied to daily life areas or public places.

Description

technical field [0001] The invention relates to a disinfectant and a preparation method thereof, in particular to a graphene disinfectant and a preparation method thereof. Background technique [0002] Disinfector (Disinfector, often called disinfectant, disinfectant water) is a liquid disinfectant, which is mainly used in various places and required disinfection work to kill bacteria, fungi, viruses and other microorganisms. [0003] According to the different places of use, disinfectant can be divided into household disinfectant, industrial grade disinfectant, food grade disinfectant, etc. According to the chemical composition, there are sodium hypochlorite (84 disinfectant), quaternary ammonium salt (94 disinfectant), chlorine m-xylenol (Dettol disinfectant, Walsh disinfectant), peracetic acid, etc. There are many types of disinfectant water. According to the different disinfection principles, they are mainly divided into oxidation, aldehyde, phenol, alcohol, alkali salt...
