Graphene anti-microbial shoe pads and preparation method thereof

Abstract

The invention provides graphene anti-microbial shoe pads. Each shoe pad comprises a skin-touching layer, an anti-microbial functional layer and an elastic damping layer, wherein a fabric of the anti-microbial functional layer contains graphene. The graphene anti-microbial shoe pads have the beneficial effects that the used anti-microbial substance is a graphene microchip, and due to the unique two-dimensional structure, graphene has the excellent anti-microbial property. Through the chemical bond connecting method, graphene and chemical fiber macromolecules are connected, thus graphene is uniformly dispersed in the prepared chemical fibers, the corresponding chemical fibers are woven to form cloth used for the shoe pads, the shoe pads fabricated by cutting the cloth have the excellent anti-microbial property, the anti-microbial effect is available no matter whether sweat exists or not, meanwhile, chemical bond connecting is adopted between the graphene microchip and the macromoleculesof the cloth, so that loss due to fall-off seldom occurs, and thus the fabricated shoe pads have long anti-microbial time and washing resistance.

Description

technical field [0001] The invention relates to a graphene antibacterial insole and a preparation method thereof, belonging to the technical field of antibacterial materials. Background technique [0002] Foot is an important starting point for the human body to run Qi and blood, run through the upper and lower viscera and meridians. After moderate exercise, the human body will sweat on the soles of the feet. Especially after strenuous exercise, the feet will sweat a lot in the small airtight space of the shoes worn. If the sweat cannot be removed in time, wet shoes will breed bacteria, leading to foot odor and beriberi, which will endanger the health of the feet. For this situation, a lot of enterprises and units disclose the invention of a lot of antibacterial deodorant insoles. [0003] Among them, the patent application number 201710422705.6 mentions that the antibacterial emulsion is prepared first, and then the insole is soaked in the antibacterial emulsion, so that t...

[0003] Among them, the patent application number 201710422705.6 mentions that the antibacterial emulsion is prepared first, and then the insole is soaked in the antibacterial emulsion, so that the antibacterial agent is attached to the insole, and then the antibacterial effect is achieved. Although this method is simple to prepare, the antibacterial agent on the insole is difficult to last for a long time. Retention, as the number of uses increases, its antibacterial agent will slowly lose until it loses its antibacterial properties

Patent application No. 201611011560.2 uses silver ion antibacterial agent, which is added to the inner layer of the fabric layer. The silver ion antibacterial agent releases silver ions after sweat contact, and the released silver ion dissolves in sweat for antibacterial and deodorizing , although the antibacterial insole prepared by this invention has better antibacterial performance, the disadvantages are also more prominent. Among them, silver ions need sweat to be antibacterial and sterilized, and the antibacterial effect is not good in a relatively dry environment. At the same time, this kind of insole is not resistant to washing , with the loss of silver ions during washing, its antibacterial effect will gradually decrease
