Abstract

The invention belongs to the field of chemical coatings, and particularly relates to a graphene nano-silver antibacterial coating and a preparation method thereof. The graphene nano-silver antibacterial coating comprises water, cellulose, a wetting agent, an antifreezing agent, a thickening agent, a defoaming agent, titanium dioxide slurry, filler slurry, a multifunctional amine auxiliary, emulsion, a sterilizing agent, a coalescing agent, a flatting agent, a formaldehyde-resistant auxiliary, and a silver-bearing antibacterial agent, and the silver-bearing antibacterial agent is graphene nano-silver dispersion liquid. According to the graphene nano-silver antibacterial coating and the preparation method thereof, a traditional formula is improved, the specially-made graphene nano-silver dispersion liquid is added to the formula, and the antibacterial effect is achieved. Nano silver can further destroy a microorganism electron transmission system, a respiratory system and a material transfer system. When the activity of thalli is lost, the nano silver can be dissociated out of the thalli and repeatedly conducts sterilization activities, and therefore the long-acting antibacterial function of the coating can be maintained. The nano silver can exert the lasting antibacterial effect by slowly releasing Ag<+>.

Description

technical field [0001] The invention belongs to the field of chemical coatings, in particular to a graphene nano-silver antibacterial coating and a preparation method thereof. Background technique [0002] The antibacterial application of silver can be traced back to BC. People at that time knew that silver can accelerate wound healing, prevent infection, purify water quality and keep fresh and antisepsis. Using silver utensils to store food can prevent the growth of bacteria and prolong the storage period of food. Li Shizhen, a medical scientist in the Ming Dynasty of my country, recorded in "Compendium of Materia Medica": silver scale has the functions of soothing the five internal organs, calming the mind, relieving panic and palpitations, and eliminating evil spirits. Taking it for a long time can lighten the body and prolong life. Western medicine also has more than 100 years of records of using silver to diagnose and treat related diseases. [0003] Silver element has...
