Description

一种石墨烯泡棉及其生产工艺
技术领域
本发明涉及发泡棉领域，具体涉及一种适用于鞋垫、床垫的石墨烯泡棉及其生产工艺。
背景技术
泡棉是塑料粒子发泡过的材料，如聚苯发泡板、聚氯乙烯发泡保温板、聚氨酯发泡棉等，用在土木建筑、制冷业、交通运输业、工程业、水上救生设备、各种仪表包装、日用杂品等行业，现有普通泡棉的缺陷在于无降解性并难以回收，对环境会有一定损害，另外普通泡棉所采用的原料有轻微毒性、异味，对人身体有害，这种泡棉不能用于鞋垫、运动护具垫等产品，而聚氨酯海藻棉具有良好的透气性、慢回弹性、抗撕裂、耐磨等特性而被广泛用于鞋垫、运动护具垫等贴身用品中。
聚氨酯发泡棉是以聚氨酯为基材利用发泡工艺制成的多孔结构材料，有开孔、闭孔和微孔之分，开孔指的是发泡材料内部泡孔与泡孔之间相互联通，与外表皮也连通，为非独立泡孔结构；闭孔指的是发泡材料内部泡孔与泡孔之间有壁膜隔开，不互相联通，为独立泡孔结构，微孔指的是发泡材料内部泡孔与泡孔之间有壁膜隔开且泡孔尺寸小于100μm，不同泡孔的聚氨酯发泡棉的特性各有差异，但是对于鞋垫、床垫等产品而言，由于其要与人贴身接触，现有聚氨酯发泡棉的导热性、抗静电性一般，功用性能不丰富。
