Abstract

The invention discloses a deodorizing high-toughness sole material and a preparation method thereof, and relates to the technical field of preparation of high polymer materials. The deodorizing high toughness sole material consists of matrix resin 80-100 weight portions, composite deodorizing agent 5-10 weight portions, toughening agent 10-25 weight portions, stuffing 20-40 weight portions, cross-linking agent 2-5 weight portions, and antioxidant 0.5-1.5 weight portions. According to the invention, the antibacterial agent with a specific structure is compounded with the adsorbent, so that a dual mechanism of bacteriostasis and deodorization is realized. The antibacterial agent inhibits bacterial growth from the source to prevent odor from generating, and the adsorbent rapidly captures the existing odor molecules, so that the synergistic effect overcomes the defects of easy loss, easy saturation and short duration of the traditional single odor-resistant component, and the durability and the comprehensive effect of odor resistance are obviously improved.
