Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to provide an antibacterial shoe which has a good antibacterial effect.

In order to achieve the purpose, the invention provides the following technical scheme:

an antibacterial shoe comprises a sole and a vamp, wherein the sole comprises the following raw materials in parts by weight,

by adopting the technical scheme, the styrene butadiene rubber has good wear resistance, heat resistance and aging resistance, and is easier to combine with sulfur, so that the sole can obtain better vulcanization effect. The butadiene rubber is made of styrene butadiene rubber, and has good elasticity, cold resistance and flexibility resistance. EVA (ethylene-vinyl acetate copolymer) foam material has the characteristics of light weight, good flexibility, excellent electrical insulation, good heat resistance and chemical corrosion resistance, and the like, and is widely applied to the field of products such as shoe materials, sports backing plates, and the like.

The zirconium phosphate silver-carrying powder is a silver-series inorganic antibacterial agent taking zirconium phosphate as a carrier. The inorganic antibacterial agent is prepared by using layered zirconium phosphate as a carrier, using various metal ions such as silver, zinc and the like as antibacterial ions and various auxiliary agents, has high safety, extremely high heat resistance and chemical stability, can be added into various resins to play an antibacterial role, and can be used for efficiently killing and removing various bacteria in a spectrum.

Zinc oxide is a wide-bandgap semiconductor oxide, has a bandgap width close to that of titanium dioxide, has a strong photocatalytic effect, and the antibacterial performance of the zinc oxide can be influenced by illumination conditions. And the zinc oxide destroys the bacterial cell membrane to cause the dissolution of cell contents, hinders the synthesis favorable for cell metabolism, destroys genetic factors, and causes the cell to lose the biological activity and the like, thereby completing the sterilization process. In addition, zinc oxide can interfere with peptidoglycan synthesis, hinder cell wall formation, and inhibit cell proliferation and growth. The zinc ions then penetrate further through the cell wall, displacing sites for cations on the cell membrane surface, binding to proteins or other anionic groups, and disrupting the metabolism and structure of the cell membrane. Meanwhile, the zinc oxide can improve the tear resistance of the rubber material, and can be used as a vulcanization activator to promote the vulcanization process.

The surface of the zirconium phosphate silver-loaded powder treated by the borate coupling agent is grafted with a borate coupling agent group, so that the viscosity of the zirconium phosphate silver-loaded powder on a system is effectively reduced, and the hydrophilicity is excessive to the hydrophobicity. The zirconium phosphate silver-carrying powder particles can not be agglomerated, the uniform dispersion is facilitated, the compatibility between the zirconium phosphate silver-carrying powder and the rubber material matrix is improved, and the antibacterial effect of the zirconium phosphate silver-carrying powder is fully exerted and improved.

Further, the sole raw material comprises 15-20 parts by weight of bamboo charcoal fiber.

By adopting the technical scheme, the tensile strength and the tear strength of the sole can be effectively improved by adding the bamboo charcoal fiber into the system. In addition, the bamboo charcoal fiber has more micropores and can adsorb and bear the zirconium phosphate silver-loaded powder, so that the antibacterial ions can be slowly released on the bamboo charcoal fiber, and the durability of the antibacterial effect is improved.

Further, the sole raw material comprises 10-12 parts by weight of oleamide.

By adopting the technical scheme, the oleamide has a certain lubricating effect, and can improve the fluidity of a rubber material system so as to improve the uniform dispersion of each component in the system. In addition, the oleamide can further reduce the surface energy of the zirconium phosphate silver-loaded powder, and improve the compatibility of the zirconium phosphate silver-loaded powder in a rubber system from agglomeration among tissue particles.

Further, the sole raw material comprises, by weight, 5-6 parts of p-chlorobenzoic acid.

Through adopting above-mentioned technical scheme, it is great to the lipophilicity of chlorobenzoic acid, and one pierces through the cell membrane of bacterium and gets into the cell internal, and then disturbs the permeability of cell membrane, inhibits the absorption of cell membrane to amino acid, and can influence the activity of the internal enzyme of bacterium to chlorobenzoic acid to reach antibacterial effect, and to chlorobenzoic acid can produce micro-hydrolysis and generate p hydroxybenzoic acid at the in-process of sole preparation, thereby strengthen antibacterial effect.

Further, the sole raw material comprises 2-3 parts by weight of polydimethylsiloxane.

By adopting the technical scheme, the polydimethylsiloxane has a good lubricating effect, and can improve the fluidity of a rubber material system so as to improve the dispersion uniformity of each component in the system and improve the brightness of the surface of the demoulded sole. By adding polydimethylsiloxane into the system, the mechanical properties such as tear strength, tensile strength and the like of the sole can be effectively improved.
