Description

一种耐热高强度纸质包装材料
技术领域
本发明涉及包装材料领域，具体是一种耐热高强度纸质包装材料。
背景技术
纸是传统的包装材料，可以对被包装物提供良好的保护作用，而且特别适合于想要得到自然感观的那些产品，对那些像褐色产品之类的不吸引人的产品来说非常有用，良好的适印性使其具有独一无二的漂亮外观，是最吸引人们眼球的一大亮点，同样，纸包装制品的优质轻量化、品种多样化，使尽可能降低邮递及运输等费用成为现实。
食品包装是包装工业的大户，占整个包装业的70％左右。近些年来，开发食品包装纸已成为食品和包装行业的共识，纸质食品包装这一绿色包装方式正以其环保性成为不可降解的包装形式的最佳替代品，在食品包装领域的优势越来越明显。
塑料包装袋袋由于其防水、机械强度大和质轻得以广泛的应用，但是塑料包装袋容易造成环境污染导致其的使用量在逐渐的降低。针对塑料包装袋的缺陷，纸质包装袋的使用数量在逐渐的增加。虽然纸质垃圾袋具有优异的可降解性，但是纸质包装袋的机械强度较差，从而导致纸质包装袋在使用过程中往往出现破裂，进而影响使用。
因此，发明一种耐热、高强度的纸质包装材料对包装产品技术领域具有积极的意义。
发明内容
本发明的目的在于提供一种耐热高强度纸质包装材料，以解决上述背景技术中提出的问题。
为实现上述目的，本发明提供如下技术方案：
一种耐热高强度纸质包装材料，由以下重量份的原料制成：

一种耐热高强度纸质包装材料，由以下重量份的原料制成：
果树枝粉50份、废弃纸张20份、植物淀粉30份、高硅氧纤维15份、聚丙烯纤维5份、乙酰化甲壳素4份、蚕丝纤维2份、氧化石墨烯7份、改性聚乙烯醇20份、填充母料13份、β-环糊精3份、植物胶5份、弹性体4份、增塑剂2份、增韧剂2份、分散剂3份、阻燃剂3份。
一种耐热高强度纸质包装材料，由以下重量份的原料制成：
果树枝粉60份、废弃纸张30份、植物淀粉40份、高硅氧纤维25份、聚丙烯纤维8份、乙酰化甲壳素8份、蚕丝纤维6份、氧化石墨烯12份、改性聚乙烯醇35份、填充母料18份、β-环糊精7份、植物胶10份、弹性体10份、增塑剂6份、增韧剂6份、分散剂5份、阻燃剂5份。
一种耐热高强度纸质包装材料，由以下重量份的原料制成：
果树枝粉55份、废弃纸张23份、植物淀粉35份、高硅氧纤维20份、聚丙烯纤维6份、乙酰化甲壳素6份、蚕丝纤维4份、氧化石墨烯9份、改性聚乙烯醇27份、填充母料15份、β-环糊精5份、植物胶8份、弹性体7份、增塑剂4份、增韧剂4份、分散剂4份、阻燃剂4份。
改性聚乙烯醇：将纳米二氧化钛分散于蒸馏水中，经超声振荡混合均匀，缓慢加入聚乙烯醇颗粒，恒温搅拌均匀，得到聚乙烯醇-纳米二氧化钛复合溶胶，胶体经胶磨后，真空抽滤脱气、静置，制得纳米纳米二氧化钛改性聚乙烯醇。
所述填充母料为超细滑石粉、纳米氧化铝、纳米蒙脱石按照质量比为1-4:1:2-5混合而成。
所述的植物淀粉为小麦淀粉、玉米淀粉、绿豆淀粉、藕淀粉、马铃薯淀粉、木薯淀粉、大豆淀粉中的一种或者至少二种。
所述的增塑剂为小分子增塑剂。
所述的增韧剂为马来酸酐接枝聚丙烯。
所述氧化石墨烯经过以下方式处理：向氧化石墨烯中加入其质量1.5倍棉籽油和0.5倍卡波姆，加热搅拌，调节pH，真空脱水得到。
所述阻燃剂为3-(3，5-二叔丁基-4-羟基)丙酸十八酯、四[β-(3,5-二叔丁基-4-羟基苯基)丙酸]季戊四醇酯、1,3,5-三甲基-2,4,6-三(3,5-二叔丁基-4-羟基苄基)苯或三(2,4-二叔丁基苯基)亚磷酸酯中的一种或多种。
与现有技术相比，本发明的有益效果是：
本发明耐热高强度纸质包装材料以果树枝粉、废弃纸张、植物淀粉为主要原料，同时配合高硅氧纤维、聚丙烯纤维、乙酰化甲壳素、蚕丝纤维、氧化石墨烯、改性聚乙烯醇及其他添加剂，有助于提高包装材料质量，抗撕裂，具备优异的力学性能，良好的耐热性能，良好的可生物降解性，而且具备成本低廉的优势，可以在市场上大量推广；
乙酰化甲壳素晶须的引入有效改善了乙酰化甲壳素晶须与高硅氧纤维、聚丙烯纤维、蚕丝纤维的相容性，纤维表面羟基可与高硅氧纤维、聚丙烯纤维、蚕丝纤维形成氢键从而促进了复合材料热稳定性和力学性能的改善，甲壳素的酰基化改性有利于晶须与纤维界面相互作用，纤维将应力通过界面层传递给晶须，晶须承担部分作用力，纤维所受作用力分散，断裂得以延缓，从而实现晶须对材料的增强增韧作用。
本发明通过添加经过处理的氧化石墨烯，首先，卡波姆分子结构中的羧基可将氧化石墨烯吸附，在pH调节过程中，卡波姆分子结构部分羧基离子化后，带有同种电荷而相互排斥，使得卡波姆分子链舒展，并良好的分散在体系中，使得预处理氧化石墨烯片层结构良好分散在体系中的，从而提升膜的力学性能；高硅氧纤维具有较好的耐高温性，能够阻止外界的水分和氧气进入体系中的，从而起到良好的防腐蚀性能；
