Description

一种可降解婴儿纸尿裤
技术领域
本发明涉及一次性卫生用品技术领域，尤其涉及一种可降解婴儿纸尿裤。
背景技术
纸尿裤又称尿不湿，是一次性使用后即可抛弃的产品，已经成为越来越多 新生婴儿不可或缺的日用品。但是，纸尿裤在给人们生活带来便利的同时，使 用后的纸尿裤如何处理也在困扰着我们，目前对废弃纸尿裤的处理方式是随生 活垃圾一起焚烧或掩埋，焚烧会产生大量的有害气体，污染环境；掩埋处理的 话由于市售的纸尿裤大多数不可降解，给生态环境造成恶劣的影响。因此如何 妥善处理废弃纸尿裤成为纸尿裤可持续发展的一大障碍，研究开发出可降解的 纸尿裤正是解决该问题的有效方法。
中国专利号：201520858958.4公开了一种节能型可降解的纸尿裤，包括尿 裤主体、吸收部分、和魔术贴，所述吸收部分纵向分布在尿裤主体的中间位置， 所述吸收部分的纵向中线上设有吸水凹槽，所述吸收部分上布有吸水沉孔，所 述尿裤主体的后腰侧上贴有魔术贴，所述尿裤主体由玉竹纤维无纺表层、玉竹 纤维无纺底层和塑料底膜组成，所述吸收部分由玉竹纤维无纺表层、聚乳酸纤 维无纺导流层、鱼蛋白水凝胶、棉芯、玉竹纤维无纺底层和塑料底膜组成。本 实用新型一种节能型可降解的纸尿裤，结构合理，即节能又环保，使用后可降 解，不产生有害物质，保护自然环境。
发明内容
因此，针对以上内容，本发明提供一种可降解婴儿纸尿裤，解决现有技术 纸尿裤使用后难以降解，易对生态环境造成恶劣影响的问题。
为达到上述目的，本发明是通过以下技术方案实现的：
一种可降解婴儿纸尿裤，包括纸尿裤本体，定义沿纸尿裤本体长度方向为 纵向，沿纸尿裤本体宽度方向为横向，所述纸尿裤本体包括由上至下依次叠层 设置的透液性面层、导流层、吸收层、防漏底层，所述透液性面层由聚乳酸无 纺布和设于其横向两侧的疏水无纺布组成，所述吸收层由吸收芯体和包裹吸收 芯体外的包裹层组成，所述吸收芯体包括上层吸收芯体和下层吸收芯体，所述 上层吸收芯体上设有复数个横向导流槽，所述横向导流槽的长度为上层吸收芯 体宽度的3/5～1，各所述横向导流槽沿纵向并排间隔设置，所述上层吸收芯体 包括第一高分子树脂层和第一蓬松无纺布层，所述第一蓬松无纺布层设于第一 高分子树脂层的下方，所述下层吸收芯体由自上而下依次叠设的第二蓬松无纺 布、第二高分子树脂层和第三蓬松无纺布层组成，所述第一蓬松无纺布层、第 二蓬松无纺布、第三蓬松无纺布的蓬松度依次减小，所述防漏底层由可降解流 延膜及设于其底部的疏水无纺布复合而成。
进一步的改进是：所述吸收层和防漏底层之间设有除臭层。
进一步的改进是：所述横向导流槽沿纵向等间距排列，间距大小为1.5～ 2.5cm。
进一步的改进是：所述横向导流槽的深度为上层吸收芯体的1/2～2/3。
进一步的改进是：所述上层吸收芯体的长度为下层吸收芯体的2/5～4/5， 宽度为下层吸收芯体的1/2～4/5。
进一步的改进是：所述可降解流延膜的制备包括以下步骤：
(1)按以下重量份称取各原料：聚乳酸70～100份、聚丁二酸丁二醇酯20～ 40份、聚乙烯醇18～25份、乙酰柠檬酸三丁酯10～20份、中空玻璃微珠5～15份、 硅烷偶联剂0.2～0.8份、抗氧剂0.1～0.4份、成膜助剂0.5～1份；
(2)将步骤(1)备好的原料倒入高速混合机内，搅拌混混均匀，然后加入双 螺杆挤出机，挤出分切造粒，制得母粒；
(3)将上述制得的母粒经过流延机成膜，冷却、预热、二次单向拉伸、冷却 定型、电晕处理、切边收卷，即得可降解流延膜。
进一步的改进是：步骤(2)中双螺杆挤出机中各挤出区间的挤出温度分别是 155～165℃、170～185℃、180～190℃、190～200℃、190～200℃、180～195℃。
进一步的改进是：步骤(3)第一次拉伸比为0.9～1.2，第二次拉伸比为1.2～ 1.6。
通过采用前述技术方案，本发明的有益效果是：
本发明制备的可降解婴儿纸尿裤，既具有吸水性好、亲肤的优点，同时具 备可降解性性，不会对环境带来大量的白色污染。其中透液性面层由聚乳酸无 纺布和设于其横向两侧的疏水无纺布组成，聚乳酸无纺布无毒、无刺激性，具 有优良的生物相容性，可再生性和可降解性。聚乳酸无纺布首先以熔融纺丝法 制得聚乳酸纤维，聚乳酸纤维再经过开松、梳理、铺网、水刺加固、卷取制得， 具有良好的物理机械性能和加工性能，手感好，本发明将聚乳酸无纺布应用在 纸尿裤的透液性面层上亲肤不刺激，不会损害婴幼儿娇嫩的皮肤。另外，聚乳 酸纤维的导湿性好、吸湿性差，因此聚乳酸无纺布能够迅速将婴儿的排泄物快 速导流下渗被吸收层吸收，较差的吸湿性可以防止尿液返渗，保持透液性面层 的干爽。
纸尿裤中的吸收层由吸收芯体和包裹吸收芯体外的包裹层组成，所述吸收 芯体包括上层吸收芯体和下层吸收芯体，双层吸收芯体的设置，可以提高纸尿 裤的吸液量。上层吸收芯体上设有复数个横向导流槽，各所述横向导流槽沿纵 向并排间隔设置，横向导流槽的设置可以使尿液快速下渗，提高吸收层的吸液 速度。上层吸收芯体包括第一高分子树脂层和第一蓬松无纺布层，下层吸收芯 体由上到下依次叠设有第二蓬松无纺布、第二高分子树脂层和第三蓬松无纺布 层，所述第一蓬松无纺布层、第二蓬松无纺布、第三蓬松无纺布的蓬松度依次 减小，该设置可以加快液体的下渗吸收，并且能有效防止液体的返渗。进一步， 在所述吸水层和防漏底层之间设有除臭层，可以达到去除臭味的效果，避免臭 味逸出影响周边环境。
优选的，所述上层吸收芯体的长度为下层吸收芯体的2/5～4/5，宽度为下 层吸收芯的1/2～4/5。该设置可以在增加吸液量的同时，节省材料，避免不必 要的浪费。
PE膜不透水，而且具有一定的透气性，因此现有纸尿裤中的防漏底层一般 由PE膜和疏水无纺布复合而成，但PE膜使用后在自然环境中几十乃至数百年都 不会降解，易造成白色污染，危害生态环境。本发明以聚乳酸为主要原料，采 用流延工艺制备得到的薄膜取代PE膜，环保可降解，不会污染环境。虽然聚乳 酸为原料制得的薄膜具有可降解性的优点，但由于聚乳酸分子链柔性不足，制 备出的薄膜硬而脆，不能很好地满足实际需求。本申请的可降解流延膜由以下 重量份称取各原料组成：聚乳酸70～100份、聚丁二酸丁二醇酯20～40份、聚乙 烯醇18～25份、乙酰柠檬酸三丁酯10～20份、中空玻璃微珠5～15份、硅烷偶联 剂0.2～0.8份、抗氧剂0.1～0.4份、成膜助剂0.5～1份。通过对聚乳酸的改性， 制得的流延膜综合性能优异，柔韧性好，拉伸强度大。在聚乳酸中加入玻璃微 珠，不仅能够增加整个体系的流动性，而且还能在保持流延膜刚性的基础上， 提高流延膜的冲击强度和断裂伸长率，改善聚乳酸本身韧性不足的缺陷。聚丁 二酸丁二醇酯是可生物降解性能的聚合物，具有良好的柔韧性，但聚丁二酸丁 二醇酯属于脂肪族直链结构聚酯，其加工性能以及刚性较差，添加到配方中由 于两种聚合物含有相似结构，因此相容性好，制得的流延膜结合了聚乳酸和聚 丁二酸丁二醇酯的优点，既具有刚性大的特性，又具有良好的韧性，弥补二者存在的不足，玻璃微珠还能改善聚丁二酸丁二醇酯的加工性能。乙酰柠檬酸三 丁酯能够削弱聚合物分子间的范德华力，增加彼此之间的相对运动能力，降低 结晶性，使聚乳酸材料的柔韧性增强。本发明的可降解流延膜通过大量优化实 验，确定了最佳的原料组合及其配比，制备得到的薄膜可生物降解，透气性好， 具有高透湿量和耐静水压，在拉伸强度没有大幅下降的同时，断裂伸长率和冲 击强度显著提升。
