Abstract

The invention provides a manufacturing method of an antibacterial air-permeable foaming insole material.The method comprises the following steps that 1, watermelon vines are sheared into watermelon vine strips, and watermelon vine crude fibers are prepared after cooking and flash explosion are conducted; 2, the watermelon vine crude fibers are treated with an alkaline hydrogen peroxide, and alkalized watermelon vine crude fibers are prepared; 3, the alkalized watermelon vine crude fibers are subjected to emulsifying and shearing through ionic liquid, and watermelon vine fibers are regenerated; 4, mixing is conducted on EVA and other auxiliaries through an internal mixer, granulation is conducted, mold pressing foaming is conducted, and an EVA composition is obtained; 5, the EVA composition is composited with the watermelon vine fibers through preimpregnation, laminated molding is achieved through a plate vulcanizing machine, and the antibacterial air-permeable foaming insole material is obtained.The manufactured insole material has the better antibacterial property and air-permeable property.

Description

Technical field: [0001] The invention relates to an insole material, in particular to a method for manufacturing an antibacterial and breathable foamed insole material. Background technique: [0002] EVA is a thermoplastic resin formed by high-pressure bulk polymerization of non-polar, crystalline ethylene monomer and polar, non-crystalline vinyl acetate monomer. Due to the introduction of vinyl acetate monomer into the molecular chain, its crystallization The temperature and melting point are lowered, and it is easy to manufacture cross-linked foaming materials by molding first and then cross-linking. The performance of EVA is mainly determined by the VA content and melt flow rate (MFI). When the MFI is constant, the VA content increases, and its elasticity and softness increase; when the VA content decreases, the rigidity, wear resistance, etc. improve. When the VA content is constant, the softening point will decrease with the increase of MFI, and the workability and su...
