Children shoe material with nano antibacterial function and preparation method thereof

Abstract

The invention discloses a children shoe material with a nano antibacterial function. The children shoe material is characterized by having an antibacterial rate of 96.12%-99.93% on staphylococcus aureus, bacillus subtilis, candida albicans, novel cryptococcus, hair mould, blue mould and aspergillus niger, wherein an inhibition zone diameter is 38.38mm-56.28mm. The invention further discloses a preparation method of the children shoe material. A nano sliver-organic antibacterial agent mixture which is efficient, low in toxicity and broad in spectrum is selected to carry out antibacterial treatment on the children shoe material, and therefore, the children shoe material is highly targeted and has better inhibitory effect on bacteria and funguses in the children shoes. The children shoe material with the nano antibacterial function disclosed by the invention is delicate in conception of the preparation method, only antibacterial treatment needs to be carried out on a finished shoe material and a shoe-making technical process is not added, and therefore, the children shoe material is strong in practicability and suitable for industrial production.

Description

technical field [0001] The invention belongs to the technical field of functional products and its manufacture, and in particular relates to a children's shoe material with nano antibacterial function and a preparation method thereof. Background technique [0002] Children are in the growth stage, and their growth and metabolism are relatively strong, especially after exercise, their sweat secretion increases sharply, causing bacteria and fungi in the shoes to multiply at a high speed and decompose a large amount of organic matter in the sweat to produce stench. If things go on like this, it will lead to foot odor, athlete's foot and A series of diseases such as beriberi directly affect children's physical and mental health. To achieve the purpose of the present invention, the inventor isolated 13 strains of bacteria, 5 strains of yeast and 8 strains of mold from the mixed microbial population in children's shoes. Among the bacteria, Staphylococcus aureus accounted for 7.70...

AI Technical Summary

Problems solved by technology

Although the following methods can give shoe materials antibacterial properties to a certain extent, there are still some problems: 1) as disclosed in CN 2741396Y (antibacterial health shoes), a kind of antibacterial and deodorant film layer with strong penetrability, bonded From the bottom of the sole pad material layer to the method above the midsole of the shoe, another example is disclosed in CN 1692852A (antibacterial health care shoes) under the surface material layer of the sole pad to use antibacterial insole glue with super penetration. Although these methods The insole has a certain antibacterial effect, but because the antibacterial material is mainly released through penetration and is away from the surface of the insole, the antibacterial effect on the surface of the insole is not direct, and it is easy to cause delayed antibacterial effect

2) For example, CN 1524910A (adhesive for antibacterial shoes) discloses an organic combination of antibacterial and deodorant materials such as silver-based antibacterial powder and adhesive, or directly adds antibacterial and deodorant materials during the production process of the adhesive. For example, CN 101862054A (an antibacterial insole) discloses that an antibacterial agent is applied to the binder resin used to bond the base sheet near the sole and the shock absorbing sheet near the insole, because these methods combine the antibacterial material with the Adhesives are mixed, so this can neither guarantee good compatibility between the antibacterial agent and the adhesive, but may cause changes in the properties of the adhesive to make the viscosity invalid, and more seriously, it will also cause the denaturation of the antibacterial agent, etc.

3) As disclosed in CN 2572803Y (dehumidification, deodorization antibacterial sole), a layer of anatase nanomaterial and activated carbon material is sprayed on the non-woven fabric layer between the upper layer of the sole and the middle layer of the sole. This method Although anatase nanomaterials have antibacterial and antifungal effects, and activated carbon has moisture absorption and deodorizing effects, this treatment method is cumbersome and not suitable for the production and application of the shoe industry.

4) For example, in CN 2792255Y (a sweat-absorbing and deodorizing antibacterial insole), it is disclosed that a silver-loaded activated carbon is arranged between the bottom layer and the adsorption layer, and physical adsorption is used to solve the problem of foot sweat and odor. CN 201085110Y (antibacterial health-care shoes) discloses the use of silver-plated fibers on soles, uppers and vamp linings. Although the silver ions accumulated in these methods make the shoe materials have good sterilization and antibacterial functions, they are only effective against Bacteria are eliminated, while the harm caused by yeast and mold is ignored

[0004] Among the above antibacterial treatment methods for shoe materials, some antibacterial effects are not direct, some are more complicated, and none of these methods are specific to children's shoes. Antibacterial agents are selected from bacteria or fungi, so the antibacterial effect is not efficient and broad-spectrum, and it is not targeted at children, a special population
