Abstract

The invention discloses a sole with a light transmitting function and a preparation method of the sole. The sole with the light transmitting function is prepared from the following raw materials in parts by weight: 35 to 60 parts of EVA (Ethyl Vinyl Acetate), 8 to 16 parts of OBC, 2 to 10 parts of ethylene propylene diene monomer, 2 to 8 parts of thermoplastic polyurethane elastomer, 0.1 to 0.9 part of zinc stearate, 0.2 to 1.2 parts of transparent zinc oxide, 0.1 to 0.9 part of a cross-linking agent and 1.2 to 6.0 parts of a transparent foaming agent, wherein the OBC is selected from any oneof OBC 9100 and OBC 9007. The sole with the light transmitting function has the advantages of better light transmittance, high hardness and tensile strength, high rebound rate, good yellowing resistance and comfortableness in wearing; the used raw materials are easy to obtain; the preparation method is simple; the production process flow is easy to operate, so the preparation method is suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a shoe sole with a light-transmitting function and a preparation method thereof. Background technique [0002] Ethylene-vinyl acetate copolymer (EVA) is a random copolymer of ethylene and vinyl acetate. Due to the introduction of short-chain branches formed by polar acetic acid groups in the ethylene chain, the original crystalline state has been changed. Compared with polyethylene, EVA becomes more flexible and elastic due to the introduction of vinyl acetate monomer in the molecular chain, and has good plasticity, elasticity and processability, and the foamed material has low density, With good mechanical properties and easy coloring, it is widely used in shoe sole materials. Although the luminous sole can increase the aesthetics and interest of the sole, the luminous layer of the sole is usually made of PU resin luminous powder or PU resin fluorescent ink. Resin lu...
