Description

一种高强度纸杯的制备方法
技术领域
本发明涉及纸杯技术领域，尤其涉及一种高强度纸杯的制备方法。
背景技术
目前，造纸工艺中为了提高生活用纸的湿强度通常是在浆料中添加湿强剂来实现。抄造生活用纸的浆料通常为长纤维和短纤维的混合体，也即浆料为针叶木浆与桑树木浆的混合浆。然而直接在混合浆中添加湿强剂，湿强剂的保留率不高，导致增加成纸湿强度的效果不够明显。
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强度纸杯的制备方法，可有效增强纸杯的强度，在保证纸杯力学性能优异的基础上，也不会对纸杯的微孔结构造成堵塞，保证纸杯的透气性，显著提高使用寿命。
本发明提出的一种高强度纸杯的制备方法，包括如下步骤：
S1、将E44型环氧树脂、聚乙二醇4000混合均匀，加入聚醚胺D230、三-(二甲胺基甲基)苯酚混合均匀，真空脱气，调节温度搅拌，冷却，干燥，粉碎得到物料a；
S2、将针叶木浆、桑树木浆、物料a、水混合，磨浆，然后加入醋酸酯纤维、丙烯酸树脂、聚酯树脂、天然橡胶、醚化淀粉混合均匀，调节体系至中性得到物料b；
S3、向物料b中加入明矾、马来松香、活性氧化钙、沸石粉、白土、抗光氧化剂混合均匀，注入杯盖的模具中，在模具压合状态下进行加热干燥，裁边得到高强度纸杯。
优选地，S1中，调节温度至80-90℃，搅拌2-8h。
优选地，S1中，E44型环氧树脂、聚乙二醇4000、聚醚胺D230、三-(二甲胺基甲基)苯酚的重量比为20-30：100-120：1-2：0.1-0.4。
优选地，S2中，针叶木浆、桑树木浆、物料a、水、醋酸酯纤维、丙烯酸树脂、聚酯树脂、天然橡胶、醚化淀粉的重量比为20-32：10-19：4-8：20-30：4-10：1-4：1-2：1-2：0.2-1。
优选地，S3中，在模具压合状态下进行加热干燥，加热干燥时间为2-3min，加热干燥温度为185-200℃。
优选地，S3中，物料b、明矾、马来松香、活性氧化钙、沸石粉、白土、抗光氧化的重量比为60-80：4-10：1-3：5-9：10-16：15-20：1-2。
本发明S1中，E44型环氧树脂与聚乙二醇4000复配，在固化剂聚醚胺D230、促进剂三-(二甲胺基甲基)苯酚的作用下发生交联反应，形成网络结构，聚乙二醇分散在网络结构中，限制了聚乙二醇结晶链段的自由运动，热稳定性好；S2中针叶木浆、桑树木浆的初生壁结构质密，经过磨浆处理后，纤维的结晶度降低，同心层产生弯曲、发生位移和变形，纤维产生裂纹及表面分丝起毛，纤维层和层间变的疏松，纤维丝层间空隙变大，物料a易于进入纤维丝层间空隙，增强了木浆纤维和醋酸酯纤维、丙烯酸树脂、聚酯树脂、天然橡胶、醚化淀粉的结合能力，纤维之间的结合能高，可有效增强纸杯的强度，在保证纸杯力学性能优异的基础上，也不会对纸杯的微孔结构造成堵塞，保证纸杯的透气性，显著提高使用寿命。本发明原料来源广，成本较低，便于大规模生产。
