Description

一种多层抗拉伸的无纺布的制备方法
技术领域：
本发明涉及无纺布生产技术领域，具体涉及一种多层抗拉伸的无纺布的制备方法。
背景技术：
随着塑料工业的蓬勃发展，废旧塑料薄膜垃圾带来的环境污染也日趋严重，白色污染成为全球瞩目的环境问题。因此，人们必须要加大力度去开发生物可降解的塑料薄膜，治理塑料废弃物对环境所带来污染问题。
无纺布占据了薄膜一部分市场，强度较薄膜强，但是寿命短，阳光直射，长时间无纺布即变脆。
淀粉是一种来源丰富、价格低廉的天然高分子材料，也是一种取之不尽用之不竭的可再生资源，它能在多种环境条件下被生物降解，最终降解产物二氧化碳和水可以通过植物的光合作用再循环，不会对环境造成任何污染。然而淀粉分子链上含有大量羟基，容易在分子链内和分子链外形成氢键，因此难溶、难熔，并且耐水性差，一遇水或长期存放在潮湿空气中容易吸收水分，影响其稳定性。
发明内容：
本发明所要解决的技术问题在于提供一种工艺简单、生产成本低且对环境友好的多层抗拉伸的无纺布的制备方法。
本发明所要解决的技术问题采用以下的技术方案来实现：
一种多层抗拉伸的无纺布的制备方法，包括：
1)薄膜的制备：EVA树脂15-20份、玉米淀粉100-150份、氰乙酸乙酯15-20份、十二烷基苯磺酸钠盐2-5份、环氧有机硅1-3份、三聚氰胺1-2份醋酸乙烯160-180份、苯甲酸1-2份、偶联剂1-3份、37％聚丙烯酰胺水溶液3-5份、一氯醋酸8-10份、40％烧碱水溶液1-2份、水200-220份；
①按配比将水和EVA树脂放入搅拌槽中，在不断搅拌下升温至60℃，使得EVA树脂溶液完全溶解，按配比将玉米淀粉和EVA树脂溶液充分混合后加入反应器中，物料在反应器中搅拌升温70-80℃，当水量减少到20％以下时，升温至150-200℃，使淀粉与EVA树脂进行反应，当物料的黏度大于50Pa·s时，终止反应，降温出料，即得磷酸酯淀粉；
②将氰乙酸乙酯和醋酸乙烯混合；
③将②中的混合后的溶剂与步骤1中的磷酸酯淀粉加入到瓶中，搅拌，5-9小时；
④再升温，加入十二烷基苯磺酸钠盐、环氧有机硅、三聚氰胺、苯甲酸、偶联剂、37％聚丙烯酰胺水溶液、一氯醋酸、40％烧碱水溶液，加热搅拌，加热温度为190℃，时长10分钟；
⑤然后用经双螺杆挤出机挤出、水冷、切割后制得双降解母料，最后经吹膜机吹膜薄膜；
2)纤维层的制备：EVA树脂15-20份、玉米淀粉100-150份、氰乙酸乙酯99-109份、聚丙烯酰胺101-120份、烧碱8-10份、尿素120-150份、五氧化二磷15-25份、水200-220份；
①按配比将水和EVA树脂放入搅拌槽中，在不断搅拌下升温至60℃，使得EVA树脂溶液完全溶解，按配比将玉米淀粉和EVA树脂溶液充分混合后加入反应器中，物料在反应器中搅拌升温70-80℃，当水量减少到20％以下时，升温至150-200℃，使淀粉与EVA树脂进行反应，当物料的黏度大于50Pa·s时，终止反应，降温出料，即得磷酸酯淀粉。
②将聚丙烯酰胺和氰乙酸乙酯混合；
③将②中的混合后的溶剂与步骤1中的磷酸酯淀粉加入到瓶中，搅拌，5-9小时；
④再升温，加入烧碱和尿素，在90-100℃下保持反应1小时；
⑤加入对五氧化二磷，终止反应，降温；
⑥然后用经双螺杆挤出机挤出、水冷、切割后制得双降解母料；
将双降解母料熔融后通过气流牵伸纺丝制成网状的长纤维层；将短纤维制成短纤维层；
3)纤维硬化：聚乙烯醇15-20份、蒸馏水130-150份、十二烷基苯磺酸钠盐2-5份、环氧有机硅1-3份、三聚氰胺1-2份醋酸乙烯160-180份、苯甲酸1-2份、37％聚丙烯酰胺水溶液3-5份；
将聚乙烯醇、环氧有机硅、十二烷基苯磺酸钠盐、三聚氰胺加入搅拌器中，搅拌10分钟，得到搅拌混合溶液；将蒸馏水倒入搅拌罐中，加温，温度控制在60-70℃，10-20分钟，至水与搅拌混合溶液完全溶解；再次加温，温度控制在70-80℃，加温30分钟；加入醋酸乙烯，维持加温反应4小时，再加入37％的聚丙烯酰胺水溶液，得到半成品；最后将苯甲酸加入半成品内，搅拌混合得到,制备完成后通过毛刷刷在纤维层上；
4)胶水的制备：端羟基二甲基硅橡胶：45-50份，二酰氧庚烷二丁基锡：0.1-0.2份，气相法白炭黑：10-15份，丁胺：5-10份，甲基三硅烷：1-2份，交联剂：1-2份，催化剂：1-2份，增韧剂：1-2份；
取20-30份端羟基二甲基硅橡胶，与交联剂、催化剂、增韧剂与5-7份气相法白炭黑混合得到A胶剂；
取剩余的端羟基二甲基硅橡胶和余下的气相法白炭黑与丁胺混合得到B胶剂；
将A与B胶剂混合，在20℃的空气中硫化3-5天,使用前60℃加热即可使用；
5)无纺布的合成：将长纤维层附在薄膜上方，短纤维层附在薄膜下方，中间涂上胶水，通过热压，完成合成。
