Description
技术领域
本发明涉及包装材料技术领域，更具体的说，是涉及一种复合缓冲材料。
背景技术
随着电子商业及快递行业的高速发展，包装废弃纸盒成为生活垃圾中的重要组成部分，而大多数运输包装纸盒都以质轻、价廉、抗弯曲强度大的瓦楞纸板作为材料，目前应用最广泛的瓦楞纸板由面纸、瓦楞芯和里纸构成，瓦楞芯侧面呈V型、U型或UV型波纹状。虽然随着环境保护和资源利用意识深化，绿色包装理念的渗透，废纸已经成为生产瓦楞纸的主要原料之一，使得瓦楞芯纸中循环利用纤维占比一般高于30％，然而大部分芯纸纸浆仍是原木纸浆，这增大了对木材的需求量，且瓦楞纸箱绝大多数都是一次性使用，导致实质上对自然资源和能源的消耗比较大，从包装生命周期评价的角度看，瓦楞纸板并不是一种绿色包装材料。
解决绿色环保的问题，就要针对瓦楞纸板材料的缺陷进行改进，有报道将一种将纺织材料与天然高分子材料复合来制备瓦楞芯纸：将稻草粉碎制浆喷涂在纺织品表面形成稻草层，后用槽辊对稻草层进行压制使其具有齿条状结构，形成芯纸，再与面纸结合成瓦楞纸板，但其工艺比较复杂，制造成本较高。
发明内容
本发明所要解决的技术问题是，克服上述现有技术中存在的不足，提供一种复合缓冲材料。
本发明复合缓冲材料，由芯材和面材组成，所述芯材的形状为双向叠加瓦楞，双向叠加瓦楞芯材两个方向的瓦楞夹角为1-90度，两个方向的瓦楞横截面形状为两个方向的瓦楞横截面形状为函数曲线或部分函数曲线的组合。
所述的函数曲线具体为正弦函数曲线、余弦函数曲线、双曲线、抛物线、幂函数曲线、指数函数曲线或对数函数曲线。
所述面材的材料为牛皮纸、白卡纸、塑料或金属。
所述芯材的材料为聚马来酸酐、聚季胺盐、聚乙二醇、聚乙烯醇、聚乙烯吡咯烷酮、聚丙烯酰胺、聚丁二酸丁二醇酯、聚丙烯酸或聚丙烯酸酯。
所述芯材的材料内部填充有纳米材料。所述芯材的表面涂覆有纳米材料。所述的纳米材料为纳米氧化锌、纳米二氧化钛，纳米碳化硅，纳米氮化硅或纳米碳酸钙。
本发明具有如下有益效果：
合成高分子材料具备机械强度较好，耐候度较好等特点，本发明将高分子材料和其他材料结合，制造一种复合材料，可以大大降低能源和自然资源的消耗，还可以增加复合材料的循环复用次数。
本发明将高分子材料通过模具成型成双向瓦楞结构后，作为芯材直接替代瓦楞纸板芯纸材料，再与面材结合成瓦楞结构复合缓冲材料，既减少了纸浆用料也减少了制造工艺步骤，而且可以提高回收利用率，减少循环利用导致瓦楞纸板性能降低的问题。还可通过对芯材双向瓦楞形状结构的改变来优化复合材料的缓冲性能。
