Description

一种高强度瓦楞纸板及其制作方法和瓦楞纸箱
技术领域
本发明涉及瓦楞纸板制造领域，具体涉及一种高强度瓦楞纸板及其制作方法和瓦楞纸箱。
背景技术
瓦楞纸板是一个多层的黏合体，又称波纹纸板。由至少一层瓦楞纸和一层箱板纸粘合而成，具有较好的弹性和延伸性，通常瓦楞纸称为芯纸，箱板纸称为面纸。主要用于制造纸箱、纸箱的夹心以及易碎商品的其他包装材料。瓦楞纸板通过土法草浆和废纸经打浆，制成类似黄纸板的原纸板，再机械加工使轧成瓦楞状，然后在其表面用粘合剂与箱板纸粘合而成。
现有的瓦楞纸板在受力变形后无法快速回弹，不能及时再次对物体起到保护作用，使得瓦楞纸板所起到的缓冲抗压能力和强度较差。
发明内容
有鉴于此，本发明的目的在于提供一种高强度瓦楞纸板及其制作方法和瓦楞纸箱，能够提高瓦楞纸板的缓冲抗压能力和强度。
为了达到上述目的，本发明提供如下技术方案：
一种高强度瓦楞纸板，所述高强度瓦楞纸板依次包括：第一防水外层、第一无纺布层、第一珍珠棉层、第二珍珠棉层、第二无纺布和第二防水外层，各层之间通过粘合剂粘合；
所述第一珍珠棉层和所述第二珍珠棉层之间设置有菱形纸筋架层；
所述菱形纸筋架层包括多个菱形纸筋架、多个瓦楞纸筋和多个瓦楞纸芯；
所述瓦楞纸芯内切设置在所述菱形纸筋架内，所述瓦楞纸筋一端连接第一珍珠棉层，另一端连接第二珍珠棉层，且相邻的两个菱形纸筋架之间通过瓦楞纸筋连接；
所述菱形纸筋架由纸筋条通过所述粘合剂粘合而成。
优选地，所述粘合剂由以下重量份的原料制成：环氧树脂25-30份，丙烯酸5-8份，丙烯酸丁酯20-25份，十二烷基磺酸钠5-8份，过硫酸铵1-2份，碳酸氢钠1-3份，3-氨丙基三乙氧基硅烷2-3份，改性纳米二氧化硅5-8份，改性石墨烯10-20份和去离子水40-50份。
优选地，所述粘合剂的制备方法包括下列步骤：
a、制备改性纳米二氧化硅和改性石墨烯；
b、将环氧树脂、丙烯酸、丙烯酸丁酯、十二烷基磺酸钠、过硫酸铵、碳酸氢钠、3-氨丙基三乙氧基硅烷、改性纳米二氧化硅、改性石墨烯和去离子水混合均匀，搅拌10-12h，即得所述粘合剂。
优选地，所述步骤a中改性纳米二氧化硅的制备方法为：将纳米二氧化硅、氨基硅烷偶联剂和体积分数为75％的乙醇溶液混合搅拌10min，用体积分数为30％的盐酸溶液调节PH至3-4，于70℃下继续搅拌反应30min，过滤，洗涤干燥，即得改性纳米二氧化硅。
优选地，所述纳米二氧化硅、氨基硅烷偶联剂和乙醇溶液的重量份比为1:1:5。
优选地，所述步骤a中改性石墨烯的制备方法为：将石墨烯置于体积分数为70％的浓硫酸和体积分数为70％的浓硝酸的混合酸中，超声处理10-12h，超声结束后，静置12-24h，过滤，洗涤干燥，即得改性石墨烯。
优选地，所述浓硫酸和浓硝酸的重量份比为2：1。
优选地，所述石墨烯、浓硫酸和浓硝酸的重量份比1：5：2.5。
本发明还提供一种高强度瓦楞纸板的制作方法，包括下列步骤：
A、将纸筋条通过粘合剂粘合而成菱形纸筋架；
B、将瓦楞纸芯通过粘合剂内切粘合在菱形纸筋架内；
C、将步骤B中相邻的两个菱形纸筋架之间通过瓦楞纸筋和粘合剂粘接；
D、将步骤B中的菱形纸筋架通过粘合剂粘合在第一珍珠棉层和第二珍珠棉层之间，将瓦楞纸筋通过粘合剂一端粘接第一珍珠棉层，另一端粘接第二珍珠棉层，以此构成第一珍珠棉层和第二珍珠棉层之间的菱形纸筋架层；
E、将第一防水外层、第一无纺布层、第一珍珠棉层、第二珍珠棉层、第二无纺布和第二防水外层，各层之间通过粘合剂粘合，即得所述高强度瓦楞纸板。
本发明还提供一种瓦楞纸箱，由上述的瓦楞纸板经过模切、压痕、钉箱/粘箱制成。
本发明中间位置增加菱形纸筋架，提高了整个瓦楞纸板的抗冲击防弯折的能力，而且在菱形纸筋架的保护下，不仅提高了抗弯力，而且提高了恢复能力；在纸板内部增加瓦楞纸芯，提高了纸板的支撑性，增加横向上的抗冲击能力，防止瓦楞纸表面受压后发生形变。本发明在瓦楞纸板的内部设置瓦楞纸筋，能够增加内部连接处的接触面积，提高连接的牢固性、稳定性和强度。
本发明先通过氨基硅烷偶联剂对纳米二氧化硅进行改性，使纳米二氧化硅带电荷，通过浓酸对石墨烯进行改性，以使得石墨烯表面含有大量羧基、羟基等功能基团，之后改性后纳米二氧化硅、改性石墨烯和其他组分通过静电吸附、分子交联进行充分混合，以最终得到粘接性良好的粘合剂。
