Description

一种具有高效隔热的纸杯其制作方法
技术领域
本发明涉及纸杯生产技术领域，具体涉及一种具有高效隔热的纸杯及其制备方法。
背景技术
纸杯作为一种常见的日常生活用品，在吃饭聚会的场合中经常出现，随着人与人之间交流的增加，纸杯的需求也在逐渐增大。纸杯可用于盛装冰激凌、奶油果酱和饮用品等，在使用纸杯喝水的过程中，为了避免被烫伤，就需要考虑到纸杯的隔热性能，市面上大多数普通纸杯外观和性能简陋，在加入热水时由于隔热性能差会使得使用者不方便握住，并且保温性能不佳，不久杯中热水便会冷却。
发明内容
为解决上述背景中存在的问题，本发明提供了一种具有高效隔热的纸杯其制作方法，其具有良好的隔热效果和保温能力。
本发明通过以下技术方案实现。
一种具有高效隔热的纸杯，包括如下重量份的原料：
混合植物纤维50～60份、混合填料7～15份、松解剂2～5份、增稠剂10～14份、阻燃剂2～4份、硅酸铝纤维7～10份、聚氯乙烯纤维7～10份。
优选的，包括如下重量份的组分：混合植物纤维55份、混合填料11份、松解剂3份、增稠剂12份、阻燃剂3份、硅酸铝纤维8.5份、聚氯乙烯纤维7.9份。
混合植物纤维的原料按重量份的组分包括：废旧纸张20～25份、玉米秸秆20～25份、干稻草20～25份。
优选的，混合植物纤维的原料按重量份的组分包括：废旧纸张21份、玉米秸秆24份、干稻草23份。
优选的，混合植物纤维的制备方法为：将废旧纸张、玉米秸秆、干稻草混合、粉碎置于纯净水中浸泡12h后过滤得滤渣，将滤渣加入到氢氧化钠溶液中小火蒸煮保持微沸2～4h以去除所含的有机质，然后将不溶物水洗处理至无色后过滤干燥备用。
混合填料的原料按重量份的组分包括：蛭石纳米粉5～11份、空心玻璃微珠4～6份、纳米海泡石纤维3～7份、纳米云母粉4～6份、纳米结晶纤维素1-2份。
优选的，混合填料的原料按重量份的组分包括：蛭石纳米粉10份、空心玻璃微珠5份、纳米海泡石纤维6份、纳米云母粉5份、纳米结晶纤维素1.5份。
优选的，混合填料的制备方法为：将蛭石纳米粉、空心玻璃微珠、纳米海泡石纤维、纳米云母粉混合均匀，研磨成90～100目的粉末，加入纳米结晶纤维素，研磨30min制成混合料，然后在600℃烘干8h待用。
本发明还公开了一种上述隔热纸杯的制备方法，具体的，包括以下步骤：
(1)将混合植物纤维、混合填料、松解剂和增稠剂加入到纯净水中，在500-800r/min下打浆2h，随后加入阻燃剂继续打浆2h，再向其中加入硅酸铝纤维、聚氯乙烯纤维继续打浆30min。加入适量的水调浆至固含量为3.5-4.5％，加热至700℃，将调好的浆料经网部及压榨部脱水成形，湿纸页进入前干阶段，在表面均匀喷涂一层聚氨酯涂层助剂；
(2)在0.06Mpa的真空条件下对成型后的湿纸进行抽吸脱水，然后电热鼓风干燥6～8min，最后在光机上进行压光，取出后即得纸，将处理好后的纸张模切后送入造杯机中，即可得到隔热纸杯。
优选的，步骤(1)所述松解剂为聚丙烯酰胺，增稠剂为聚乙烯吡咯烷酮。
优选的，步骤(1)所述阻燃剂为磷酸三(1,3-二氯丙基)酯。
优选的，步骤(1)中纯净水的质量是所述混合植物纤维的1.2～10倍。
本发明的有益效果为：本发明在打浆过程中向混合植物纤维中添加以蛭石纳米粉为主体的隔热填充材料，在混合植物纤维打浆过程中，水中纸浆纤维受到剪切力的作用，纤维的形态被改变，纤维的细胞壁发生位移、变形与破裂从而吸水润胀，由于混合隔热填充材料为纳米尺度，在这个过程中这些纳米尺度的混合隔热填充材料很好的和这些发生改变的植物纤维结合附着在一起，从而植物纤维整体的隔热性能得到了提升。同时加入的硅酸铝纤维和聚氯乙烯纤维是一种很好的功能助剂，能够与纳米尺寸的隔热填充材料以及混合植物纤维相互配合，在材料内部形成稳定的三维隔热网状结构，大大提高了制得纸杯的隔热能力。此外，蛭石也具有优秀的阻燃能力，磷酸三(1,3-二氯丙基)酯作为阻燃剂能进一步增强材料的阻燃能力。另外，当温度升高时蛭石纳米粉会发生膨胀，也起到了很好的隔热作用。因此，所制得的纸杯同时具有了优秀的隔热和保温效果。
