Abstract

The invention discloses a composite antibacterial deodorizing shoe material. The composite antibacterial deodorizing shoe material comprises a base material layer and a high-pore-volume high-air-permeability and moisture-permeable coating. The high-pore-volume high-air-permeability and moisture-permeable coating is prepared from the following raw materials in parts by weight: 11-15.5 parts of an ethylene-vinyl acetate copolymer, 40-55 parts of a large-aperture hollow silicon dioxide nanoparticle aqueous dispersion, 25-32 parts of a polyvinyl alcohol aqueous solution, 1-3 parts of a dispersing agent and 3-10 parts of composite antibacterial powder. The composite antibacterial deodorizing shoe material has the advantages that the peculiar smell reduction rate is high (the peculiar smell removal rate is high); the normal emissivity is high, densely-distributed miniature pores in the structure are showed to form an effect similar to a black body, the adsorption effect on the peculiar smell is good, and high pore volume and high air and moisture permeability are achieved; the antibacterial rate on staphylococcus aureus is high, and the antibacterial effect on various bacteria such as escherichia coli and candida albicans is good; and in addition, the mechanical properties such as tensile strength are excellent, the rebound rate is high, the permanent compression deformation rate is small, and the comprehensive use performance is good.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a composite antibacterial and deodorizing shoe material and a preparation method thereof. Background technique [0002] As a polymer material, ethylene-vinyl acetate copolymer (EVA) has good plasticity, elasticity and processability, and the EVA material after foaming treatment has the advantages of low density, good mechanical properties, and easy coloring. Therefore, EVA is often widely used in various sole materials. [0003] EVA rubber and plastic products are new environmentally friendly plastic foam materials, which have the advantages of good cushioning, shock resistance, heat insulation, moisture resistance, and chemical corrosion resistance, and are non-toxic and non-absorbent. EVA rubber and plastic products can be processed and shaped after design. Its shockproof performance is better than traditional foaming materials such as polystyrene (foam), and it meet...
