Description

一种降低尿液刺激性的尿不湿
技术领域
本发明涉及尿不湿产品技术领域，尤其涉及一种降低尿液刺激性的尿不湿。
背景技术
尿不湿是婴儿常用的日用品，是纸尿片、纸尿裤、拉拉裤的统称。干爽的尿不湿可以使婴儿保持整夜的安睡，由于吸水性强，被俗称为“尿不湿”。纸尿裤一般由三个主要部分组成︰面层、导流层、吸收芯层和底布。表面包覆层紧贴婴儿的身体，能够促使尿液快速渗透并有效阻止回渗，保持尿裤表层干爽。国内市场上的纸尿裤基本上是无纺布面层，透气无纺布能提升尿裤内部的透气程度，水蒸气可以流通至纸尿裤以外，及时排出湿气、热气，有效减少湿疹发生几率，柔软舒适不刺激皮肤；导流层是位于面层和吸收芯层之间的一种材料，一般是木浆纤维复合材料、织物或泡沫材料，能快速吸收大量液体、防止液体侧漏、阻止液体反渗等作用；吸收芯层主要是能够俘获并快速吸收尿液、分散尿液或能通过毛细作用把它扩散到整个芯层中、最终吸收并储存尿液，国内市场上纸尿裤的吸收芯层，主要是由纯木浆(绒毛浆)和高吸水树脂(SAP)构成层状结构；底布部分多采用触感舒适的无纺布、PE膜等材料。
婴幼儿在使用尿不湿的过程中最大的困扰就是蓄积的尿液对婴儿皮肤产生的刺激，严重的会导致尿布疹、湿疹，给婴儿造成健康危害。尿液中的尿素、氨、尿酸等物质是刺激皮肤细胞最主要的物质，因此提高尿不湿对氨的吸附和排除能力将会极大的降低尿不湿对婴幼儿皮肤的伤害。
发明内容
本发明为了弥补已有技术的缺陷，提供一种降低尿液刺激性的尿不湿。
本发明是通过以下技术方案实现的：
一种降低尿液刺激性的尿不湿，所述的尿不湿从上至下依次包括面层、导流层、吸收芯层和底膜，所述的吸收芯层包括非织布包裹层、高吸水性树脂和/或绒毛浆，所述的导流层经过脲酶抑制剂-纳米银溶胶整理，所述的非织造布包裹层含有氨氮吸附剂。
所述的脲酶抑制剂-纳米银溶胶是由以下配方量的原料制备得到：脲酶抑制剂1-5、银氨溶液2-5、1%-5%的氢氧化钠水溶液100-500，制备方法：将脲酶抑制剂溶于氢氧化钠水溶液，搅拌混合均匀后置于微波反应器中，调节微波功率为600-800W，微波温度为50-80℃，然后用注射器将新配制的银氨溶液通过水相滤膜注入上述木质素溶液中，微波反应60-120min后即得。
所述的脲酶抑制剂为木质素或茶多酚。
所述的整理为浸润或涂布。
所述的氨氮吸附剂为有机化的微米或纳米量级硅藻土、活性炭或沸石。
所述的氨氮吸附剂的制备方法为：将微米或纳米量级硅藻土、活性炭或沸石与50%乙醇溶液混合制成浆液，然后加入聚乙二醇400，高速搅拌混合1-2h后干燥即得，其中硅藻土、活性炭或沸石、乙醇溶液、聚乙二醇400三者的质量比为1：（1-5）:（0.1-0.2）。
所述的非织造布包裹层是由聚丙烯与氨氮吸附剂共混后熔融纺丝制备得到的，其中聚丙烯与氨氮吸附剂的重量比为1:（0.01-0.1）。
本发明制备了一种能有效降低尿液刺激性的尿不湿产品，这种尿不湿对传统尿不湿的导流层和吸收芯层分别进行改性处理，用含有纳米银的脲酶抑制剂对导流层材料进行整理，附着在导流层的纳米银和脲酶抑制剂有杀菌、抑制尿素等含氮物质代谢分解的作用，有效的保护了婴儿臀部的肌肤；用含有硅藻土、沸石、活性炭等氨氮吸附性材料制成的非织造布材料作为吸收芯层的包裹层，可以有效的吸附由存储到高吸水性树脂中的尿液所产生的氨氮化合物；本发明通过对尿不湿中的导流层和吸收芯层包裹层进行功能性改性处理降低了尿液对婴儿肌肤的刺激，进一步的呵护了婴儿的肌肤，同时通过这种功能划分的处理避免了处理剂对原本材料性能的不良影响，也提升了产品的使用周期，多次吸尿后仍能保持较低的氨氮量，为婴儿皮肤营造更为温和的氛围。
具体实施方式
一种降低尿液刺激性的尿不湿，该尿不湿从上至下依次包括面层、导流层、吸收芯层和底膜，其中吸收芯层包括非织布包裹层、高吸水性树脂和绒毛浆，其导流层经过脲酶抑制剂-纳米银溶胶涂布，而非织造布包裹层中含有氨氮吸附剂。
使用的脲酶抑制剂-纳米银溶胶是由以下配方量的原料制备得到：脲酶抑制剂2.5、银氨溶液3.5、2.5%的氢氧化钠水溶液300，制备方法：将木质素溶于氢氧化钠水溶液，搅拌混合均匀后置于微波反应器中，调节微波功率为650W，微波温度为65℃，然后用注射器将新配制的银氨溶液通过水相滤膜注入上述木质素溶液中，微波反应80min后即得。
采用的氨氮吸附剂为有机化的微米量级硅藻土，其制备方法为：将微米量级硅藻土与50%乙醇溶液混合制成浆液，然后加入聚乙二醇400，高速搅拌混合1h后干燥即得，其中硅藻土、50%乙醇溶液、聚乙二醇400三者的质量比为1：2.5:0.15。
将制备得到的氨氮吸附剂与聚丙烯按照1:0.05的重量比共混后熔融纺丝，即得到所述的非织造布包裹层。
