Description

一种防水抗压纸箱的制备方法
技术领域
本发明属于纸箱加工技术领域，特别涉及一种防水抗压纸箱的制备方法。
背景技术
纸箱是应用最广泛的包装制品，按用料不同，有瓦楞纸箱、单层纸板箱等，有各种规格和型号。现有的纸箱仍存在一定的问题，比如纸箱强度脚底，不耐压，在运输过程中，由于外力会造成纸箱的碰撞，损害到纸箱内的物品，难以起到对物品很好的包装效果，且遇到雨天、雪天等潮湿天气时，纸箱经常受潮变软、甚至腐烂，起不到保护物品的作用，有时候反而影响物品的质量，给使用者带来损失。因此，需要对纸箱进行进一步的研究，以使其能够更好的适应当今社会的发展需要。
发明内容
本发明要解决的技术问题是克服上述缺陷，提供一种防水抗压纸箱的制备方法。
为了解决上述技术问题，本发明的技术方案为：
一种防水抗压纸箱的制备方法，包括如下步骤：
（1）选基板，在基板的一侧涂覆粘胶剂，并贴合在与基板大小、长宽相同的缓冲垫，将粘合后的基板放置通风干燥处，放置晾干；
（2）选取与缓冲垫大小相同的防水瓦楞纸板，在瓦楞纸板面向缓冲垫的一侧涂覆胶黏剂，将瓦楞纸板与缓冲垫贴合后，晾干；其中所述防水瓦楞纸板主要由以下重量份的原料制备而成：竹浆40-50份、木浆35-45份、改性石膏纤维15-30份、钠基膨润土10-20份、聚乳酸8-15份、氧化淀粉5-10份、木聚糖 3-8份、防水剂3-5份、阻燃剂1-3份；
（3）在防水瓦楞纸板和基板一侧分别喷涂防水乳液，晾干即得纸箱板；其中所述防水乳液包括如下重量份的原料：丙烯酸乳胶20-30份、松香10-20份、改性硅藻土10-20份、钛白粉5-10份、羟丙基甲基纤维素醚3-5份、表面活性剂1-3份；
（4）将步骤（3）中纸箱板进行切割、碰线、切角、顶箱操作，即制作成纸箱。
优选的，步骤（1）所述缓冲垫为橡胶垫。
优选的，步骤（2）所述胶黏剂包括如下重量份的原料：水50-60份、糊化淀粉20-30份、改性酚醛树脂10-20份、酮醛聚乙烯醇化合物3-5份、阿拉伯胶3-5份、硼砂0.3-0.5份。
优选的，步骤（2）所述改性石膏纤维通过如下方法制备所得：将石膏纤维浸润到石墨烯浆料中，然后加入丙烯酰胺、氧化淀粉、明胶，同时加入引发剂搅拌反应，过滤干燥所得。
优选的，步骤（2）所述防水剂为硅酸钠、硅酸镁铝、羟乙基纤维素、聚乙基羟基硅氧烷按3-5:2-3:1-2:1的重量配比混合搅拌均匀后制得。
优选的，步骤（2）所述阻燃剂为改性滑石粉、硅酸钠、纳米氧化钛按1:1-2:1-3的重量配比混合搅拌均匀后制得。
优选的，步骤（2）所述防水瓦楞纸板通过如下方法制备所得：
（1）按重量份向竹浆、木浆混合液中加入改性石膏纤维，混合均匀，将得到的纸浆液静置3-6h，去除悬浮的杂质后进行离心分离，然后将得到的纸浆洗涤至中性后进行过滤，备用得到浆液A；
（2）按比例将钠基膨润土、聚乳酸、氧化淀粉、木聚糖加水搅拌混合均匀，得到浆液B；
（3）将步骤（1）得到的浆液A和步骤（2）得到的浆液B混合，加入防水剂、阻燃剂，搅拌混合后导入挤压机挤出成型，烘干，即得防水瓦楞纸板。
优选的，步骤（3）所述防水乳液包括如下重量份的原料：丙烯酸乳胶25份，松香20份，改性硅藻土15份，钛白粉8份，羟丙基甲基纤维素醚4份，表面活性剂2份。
优选的，步骤（3）所述改性硅藻土通过如下方法制备所得：将硅藻土加入到表面活性剂溶液中，超声分散，加入氨基硅烷偶联剂搅拌，烘干得改性硅藻土。
与现有技术相比本发明的有益效果是：
（1）本发明采用浆内添加防水剂和表面喷施防水乳液两段组合技术，将浆内添加防水剂，再通过在防水瓦楞纸板和基板一侧分别喷涂防水乳液，制成纸箱，复合防水体系能产生协效防水作用，保证了纸箱的防水性能。
（2）本发明防水瓦楞纸板配料中添加石墨烯改性的石膏纤维，借助凝胶包覆层的高韧性和石墨烯的增强作用，能够增加石膏纤维与纸浆的亲合力，增加改性石膏纤维与纸张的附着力，显著提升纸张的强度和韧性，使后续制备的纸箱具有优良的抗压强度，有效的保护纸箱内的物品。
（3）本发明防水瓦楞纸板中添加防水剂、阻燃剂，使纸盆的防潮防水性和阻燃性均得到较大的提高，防潮防水性的提高还进一步增强了阻燃效果。
（4）本发明采用的胶黏剂具有防水、耐水功能，不会因为纸箱沾水或受潮纸箱粘合处就软化失去作用。
（5）本发明工艺简单、生产成本低，操作方便，制备的纸箱防水、阻燃、抗压性能好，具有极其高的防摔性，具有较广阔的市场前景。
