Description
技术领域Technical Field
本发明涉及共混材料技术领域，特别是涉及一种共混改性高弹材料及其弹性发泡鞋材的制备方法。The invention relates to the technical field of blended materials, and in particular to a preparation method of a blended modified high-elastic material and an elastic foamed shoe material thereof.
背景技术Background Art
现有的运动鞋底分为硫化橡胶底、气垫填充底和发泡底三大类，而随着科学技术的不断发展，发泡底因兼具性能优良和成本低廉的优势，在运动鞋底占据了较大的市场份额。由于EVA及其共混发泡材料质轻、保暖舒适、成本低，目前，世界上各种品牌的运动鞋的底部绝大部分使用EVA及其共混物的发泡材料。Existing sports shoe soles are divided into three categories: vulcanized rubber soles, air cushion filled soles and foam soles. With the continuous development of science and technology, foam soles have occupied a large market share in sports shoe soles due to their advantages of excellent performance and low cost. Since EVA and its blended foam materials are light, warm and comfortable, and low in cost, at present, most of the soles of various brands of sports shoes in the world use EVA and its blended foam materials.
但使现有的EVA及其共混发泡材料的密度较大，弹性不够，弹性为30％～42％，而篮球鞋、跑步鞋等运动鞋的中底则要求具有高弹性(回弹性大于50％)，且柔软度、压缩变形性能和力学性能较差，因此现有的EVA发泡材料不能满足要求。However, the existing EVA and its blended foaming materials have a high density and insufficient elasticity, which is 30% to 42%. The midsoles of sports shoes such as basketball shoes and running shoes are required to have high elasticity (resilience greater than 50%), and their softness, compression deformation performance and mechanical properties are poor. Therefore, the existing EVA foaming materials cannot meet the requirements.
鉴于此，本申请旨在提供一种共混改性高弹材料及其弹性发泡鞋材的制备方法，以更好地解决上述技术问题。In view of this, the present application aims to provide a method for preparing a blended modified high-elastic material and an elastic foamed shoe material thereof, so as to better solve the above-mentioned technical problems.
