Shoe and clothing waste hybrid reinforced and toughened cement mortar material and preparation method thereof
The invention discloses a shoe and clothing waste hybrid reinforced and toughened cement mortar material and a preparation method thereof.The preparation method comprises the steps that firstly, waste sole materials containing ethylene-vinyl acetate copolymer (EVA) foam midsoles and polyurethane elastomer outsoles are added into solid-phase shearing and grinding equipment, and strong mechanical shearing force is applied; superfine grinding and mechanochemical decrosslinking are realized, so that good dispersity and surface activity are achieved; and then uniformly mixing the mixture with cotton-polyester blended fabric fibers subjected to mechanical opening and activation with raw materials such as Portland cement and river sand to prepare the shoe and clothing waste hybrid reinforcing and toughening cement mortar material. According to the invention, shoe and clothing wastes which are difficult to recover and separate are upgraded and recovered and are applied to the cement-based composite material, so that low-carbon recycling of the product is realized. The compressive strength of the obtained cement-based material is improved by 63%, and the breaking strength is improved by 49%.
本申请公开了一种鞋服废弃物杂化增强增韧水泥砂浆材料及其制备方法，先将包含乙烯‑醋酸乙烯共聚物(EVA)泡沫中底与聚氨酯弹性体大底的废弃鞋底材料加入到固相剪切碾磨装备中，通过施加强大的机械剪切力作用，实现超细粉碎和力化学解交联，赋予其良好的分散性和表面活性；然后将其与机械开松活化后的涤棉混纺织物纤维一起，与硅酸盐水泥、河沙等原料混合均匀后制得鞋服废弃物杂化增强增韧水泥砂浆材料。本申请将难回收、难分离的鞋服废弃物升级回收，应用到水泥基复合材料中，实现产品低碳回收利用。所得水泥基材料的抗压强度提升63％、抗折强度提升49％。
