Description
技术领域
本发明涉及一种超强代木重型瓦楞纸板，属于包装材料技术领域。
背景技术
瓦楞纸箱具有质量轻、结构性能好、耐戳穿、防震、缓冲、可折叠、印刷适应性强、规格变更容易、环保可回收及适合自动化包装作业等优点，在与其他包装材料的激烈竞争中，瓦楞纸箱以其独特的性能，成为迄今为止常用不衰、发展迅猛的纸质包装容器，成为现代包装中最重要的一种包装形式。
一般瓦楞纸箱只宜装载轻质物品，怕水怕潮，不宜长久储存，所以化工、机械等重载荷产品的出口，大多采用木质包装箱和铁桶，其缺点是：成本高，不符合环保要求；运输、储存时占用空间大，用后难以处理；木箱出口需经熏蒸处理等。国内外都在积极研制开发“重型瓦楞包装纸箱”，提高瓦楞纸箱的抗压强度，力图以纸代木，以纸代金属，在低碳经济中，减少资源消耗，降低生产成本。
2009年8月27日，国务院七部委就“包装节材代木”工程，发出联合通知，将重型瓦楞纸板等新材料，列入今后一阶段国家包装行业的研发应用重点。
发明内容
本发明目的是提供一种超强代木重型瓦楞纸板。
为达到上述目的，本发明采用的技术方案是：一种超强代木重型瓦楞纸板，包括面纸（1）、芯纸（2）、芯纸（3）、和里纸（4）；所述面纸（1）和芯纸（2）之间、芯纸（2）和芯纸（3）之间以及芯纸（3）和里纸（4）之间均设有瓦楞结构层（5）；所述瓦楞结构层（5）均由第一瓦楞纸层（6）、聚醋酸乙烯酯刚性骨架（8）、第二瓦楞纸层（7）粘合而成，所述聚醋酸乙烯酯刚性骨架的形状与所述第一瓦楞纸层和第二瓦楞纸层的形状匹配，所述聚醋酸乙烯酯刚性骨架夹设在所述第一瓦楞纸层和第二瓦楞纸层之间。
优选的技术方案为：所述面纸、芯纸和里纸的材质均采用440g/m2的牛皮箱板纸。
优选的技术方案为：所述聚醋酸乙烯酯刚性骨架为一层波纹状的固态聚醋酸乙烯酯薄膜层，该聚醋酸乙烯酯薄膜层的厚度为25~35g/m2。
优选的技术方案为：所述第一瓦楞纸层和第二瓦楞纸层均采用100g/m2的瓦楞纸，该瓦楞纸的楞型为BCA楞，也适用于其他楞型，如AAA或AAC。
由于上述技术方案运用，本发明与现有技术相比具有下列优点和效果：
由于本发明在面纸和芯纸之间、芯纸和芯纸之间以及芯纸和里纸之间均设有瓦楞结构层，在第一瓦楞纸层和第二瓦楞纸层之间夹设聚醋酸乙烯酯刚性骨架，该聚醋酸乙烯酯刚性骨架既用来固定第一瓦楞纸层和第二瓦楞纸层，也在第一瓦楞纸层和第二瓦楞纸层之间形成刚性骨架，从而起到了强化瓦楞结构的作用，故复合十层三瓦楞纸板具有很高的物理技术强度指标，其各项物理技术指标为：边压强度>30000N/m，戳穿强度42.51J。
附图说明
附图1为一种超强代木重型瓦楞纸板示意图。
以上附图中：1、面纸；2、芯纸；3、芯纸；4、里纸；5、瓦楞结构层；6、第一瓦楞纸层；7、第二瓦楞纸层；8、聚醋酸乙烯酯刚性骨架。
具体实施方式
下面结合附图及实施例对本发明作进一步描述：
须知，本说明书所附图式所绘示的结构、比例、大小等，均仅用以配合说明书所揭示的内容，以供熟悉此技术的人士了解与阅读，并非用以限定本发明可实施的限定条件，故不具技术上的实质意义，任何结构的修饰、比例关系的改变或大小的调整，在不影响本发明所能产生的功效及所能达成的目的下，均应仍属本发明所揭示的技术内容所能涵盖的范围内。同时，本说明书中所引用的如“上”、“下”、“左”、“右”、“中间”及“一”等的用语，亦仅为便于叙述的明了，而非用以限定本发明可实施的范围，其相对关系的改变或调整，在无实质变更技术内容下，当亦视为本发明可实施的范畴。
实施例：一种超强代木重型瓦楞纸板
参见附图1所示，一种超强代木重型瓦楞纸板，包括面纸1、芯纸2、芯纸3和里纸4；所述面纸1和芯纸2之间，芯纸2和芯纸3之间以及芯纸3和里纸4之间均设有瓦楞结构层5。所述瓦楞结构层5均为复合结构，即由第一瓦楞纸层6、聚醋酸乙烯酯刚性骨架8和第二瓦楞纸层7粘合而成，所述聚醋酸乙烯酯刚性骨架8的形状与所述第一瓦楞纸层6和第二瓦楞纸层7的形状匹配，所述聚醋酸乙烯酯刚性骨架8夹设在所述第一瓦楞纸层6和第二瓦楞纸层7之间。所述面纸、芯纸和里纸的材质均采用440g/m2的牛皮箱板纸。所述聚醋酸乙烯酯刚性骨架为一层波纹状的固态聚醋酸乙烯酯薄膜层，该聚醋酸乙烯酯薄膜层的厚度为25~35g/m2。所述第一瓦楞纸层和第二瓦楞纸层均采用100g/m2的瓦楞纸，该瓦楞纸的楞型为BCA楞。所述聚醋酸乙烯酯刚性骨架8为固化后的波纹状聚醋酸乙烯酯薄膜，可以采用聚醋酸乙烯酯胶粘剂涂层或者聚醋酸乙烯酯乳液涂层经固化后构成，其中的聚醋酸乙烯酯为热塑性材料，经固化后有着良好的刚性。
性能测试：以美国的ASTM纸箱标准进行配材。在美标中，三瓦楞纸箱内装物的最大质量可达82kg，此时纸板面纸、里纸的质量都为440g/m2。
经国际SGS机构权威检测，超强代木重型瓦楞纸板的关键指标已远远超过美标规定的最高要求。对比结果见下表：
| 关键指标 | 本技术实施例：SGS测试（峰值） | 德标DIN 55468-1 | 美标ASTM | GB6544/T-2008 三瓦楞纸板最强标准 |
| 边压强度（N/m） | >30000 | 24000 | 19600 | ≧15500 |
| 戳穿强度( J ) | 42.51 | 33 | 39 | - |
| 耐破强度(kPa) | - | - | - | ≧2500 |
由上表可知，实施例一制得的超强代木重型瓦楞纸板，其物理指标已超过美欧的先进水平，远超国标GB6544/T-2008中规定的三瓦楞纸板最强标准。
本发明是利用聚醋酸乙烯酯材料固化后形成的刚性骨架支撑整个的瓦楞纸板，起到结构强化的作用，因此必须要在两张瓦楞纸之间满版涂胶。本发明选用聚醋酸乙烯酯胶粘剂涂层是最佳技术方案。聚醋酸乙烯酯胶粘剂由主体成分聚醋酸乙烯酯和其它助剂组成，从而使得聚醋酸乙烯酯胶粘剂既具有胶粘剂的特性即粘结固定作用，也具有聚醋酸乙烯酯材料本身的作用即其为热塑性材料而具备固化后起的刚性支撑作用，当本发明使用以聚醋酸乙烯酯材料为基本材料的其它产品例如聚醋酸乙烯酯乳液时，其粘结作用下降，但是其也能够满足本发明的要求，其固化后起的刚性支撑作用则与使用聚醋酸乙烯酯胶粘剂时相同。
对比例二，用一张200g/m2的瓦楞纸替代实施例的瓦楞结构层（100g/m2瓦楞纸+聚醋酸乙烯酯刚性骨架+100g/m2瓦楞纸），在其它材质、加工条件相同的情况下，加工成常规七层三瓦楞纸板，测试结果显示：其边压强度仅为23968N/m，戳穿强度28J，都明显低于实施例一制得的超强代木重型瓦楞纸板。该结果说明1+1>2，也说明瓦楞结构层中的聚醋酸乙烯酯刚性骨架起到刚性骨架的支撑作用。
聚醋酸乙烯酯刚性骨架的材质聚醋酸乙烯酯为一种热塑性树脂，其经固化后可以在两瓦楞纸之间形成一具有力学性能的固定结构，因此其可以作为具有支撑作用的刚性骨架用来支撑面纸和里纸。聚醋酸乙烯酯刚性骨架同时具有良好的耐冲击、阻隔、防潮、防水性，所以复合后的瓦楞纸板具有较高的戳穿强度、耐破强度、阻隔性能（透气性、吸水性、吸油性）。
上述实施例只为说明本发明的技术构思及特点，其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围之内。
