Description

一种高隔热性纸杯
技术领域
本发明涉及纸杯，具体涉及一种高隔热性纸杯。
背景技术
纸杯具有防水、防油、耐热、不渗漏、无污染、无异味、强度好、质感好、可自然降解和回收价值大等特点。饮茶人常将滚开的开水倒入纸杯内进行泡茶，纸杯的外部温度较高，纸杯是没有把手的，而现有纸杯的隔热性能不高，经常有人被烫伤。
发明内容
基于背景技术存在的技术问题，本发明提出了一种高隔热性纸杯。本发明具有优异的隔热性能。
本发明提出的一种高隔热性纸杯，其原料按重量份包括：中草药渣32-43份、植物纤维17-30份、钛白粉12-20份、隔热材料6-12份、牡蛎壳粉3-11份、增粘剂5-15份。
优选地，其原料按重量份包括：中草药渣36-40份、植物纤维20-26份、钛白粉14-17份、隔热材料8-10份、牡蛎壳粉5-8份、增粘剂8-12份。
优选地，所述隔热材料的制备方法为：将凹凸捧土置于水中浸泡沉降1-2个月后，烘干，冷却至室温，研磨过300-400目筛，得到预处理凹凸捧土；将硅烷偶联剂溶解于15-25wt％的乙醇溶液中，加入1.2-1.7重量份预处理凹凸捧土和2.2-3.6重量份钛酸钾晶须，磁力搅拌，抽滤，弃滤液，洗涤，干燥，得到改性纳米珍珠岩。
优选地，所述烘干的温度为50-70℃。
优选地，所述硅烷偶联剂选自KH-550、KH-570、甲基三乙氧基硅烷中的一种。
优选地，所述磁力搅拌的温度为85-100℃，时间为4-6h。
优选地，所述干燥的温度为75-90℃，时间为30-50min。
本发明可按照常规方法进行制备。
本发明的原料包括：中草药渣、植物纤维、钛白粉、隔热材料、牡蛎壳粉、增粘剂，各原料之间相容性好，赋予本发明良好的基础性能。优选方案中，采用钛酸钾晶须改性凹凸捧土，磁力搅拌下，排除晶须里面的空气，使凹凸捧土逐步填空到晶须的空隙中，在硅烷偶联剂的作用下，钛酸钾晶须与凹凸捧土通过活性位点相互作用，使两者分散更加均匀，得到结合紧密的复合物；由于凹凸棒土是一种晶型为2：1的富镁硅酸盐黏土矿物，其结构为层链状，外观呈针状或纤维，其比表面积大，特殊的层链状晶体结构使其具有发达的沸石类孔道，形成聚集多孔结构，气体被封闭于无数微小非连通的孔道内，使对流传热效率可忽略不计，其与钛酸钾晶须复合后，能够有效提高其力学性能，增强其热阻作用，进而提高本发明的隔热性能；且对凹凸捧土进行低温预处理，能够脱去凹凸捧土内的沸石水、吸附水和结晶水，使凹凸捧土的针棒状团疏松多孔，激活封闭的孔道，增大比表面积和孔隙容积，为与烷基偶联剂反应提供更多的活性位点。
