Description

一种墙面复合无纺布的制备方法
技术领域：
本发明涉及无纺布生产技术领域，具体涉及一种墙面复合无纺布的制备方法。
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墙面复合无纺布的制备方法。
本发明所要解决的技术问题采用以下的技术方案来实现：
一种墙面复合无纺布的制备方法，其特征在于：包括：
1)薄膜的制备：磷酸氢二钠15-20份、玉米淀粉100-150份、聚乙烯45-55份、甘油10-15份、鱼磷胶5-10份、聚乳酸5-8份、纳米二氧化硅3-8份、石蜡5-10份、过氧化二异丙苯1-4份、炙款冬花10-12份，炒桔梗5-8份，炙僵蚕10-12份，川贝母3-5份，炙罂粟壳3-5份，炙全蝎1-2份，花茶4-5份；
将组成原料中的炙款冬花、炒桔梗、炙僵蚕、川贝母、炙罂粟壳和炙全蝎，放入蒸馏瓶中，加入5倍的清水，蒸煮，至蒸馏瓶中的水蒸干，收集水蒸气，水蒸气重新液化；同时将花茶放入开水中浸泡，水量为300ml，浸泡5-8分钟，过滤水，得到花茶水；再将收集的水蒸气与花茶水混合，得到混合液；
按配比将混合液和磷酸氢二钠放入搅拌槽中，在不断搅拌下升温至60℃，使得磷酸氢二钠溶液完全溶解，按配比将玉米淀粉和磷酸氢二钠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℃，当混合液减少到20％以下时，升温至150-200℃，使淀粉与磷酸氢二钠进行反应，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；
机械搅拌下依次向甘油和鱼磷胶中加入聚乳酸、纳米二氧化硅、石蜡和过氧化二异丙苯，然后与聚乙烯和制备的磷酸酯淀粉一起加入到高速混合机中，充分混合；
将混合均匀的物料加入到挤出机中，经螺杆的转动、挤压和搅拌，物料在一定温度作用下熔融塑化，并在螺杆推动下，经过滤网、分流板后通过机头环形口模间隙挤出成薄壁管，然后在流动状态下趁热用压缩空气将其吹胀，冷却定型、夹平，由导辊压紧牵引入卷取辊，即得薄膜；
2)纤维层的制备：磷酸氢二钠15-20份、玉米淀粉100-150份、苯酚99-109份、甲醛101-120份、烧碱8-10份、尿素120-150份、氢氧化铵15-25份、水200-220份；
①按配比将水和磷酸氢二钠放入搅拌槽中，在不断搅拌下升温至60℃，使得磷酸氢二钠溶液完全溶解，按配比将玉米淀粉和磷酸氢二钠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℃，使淀粉与磷酸氢二钠进行反应，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将甲醛和苯酚混合；
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加入对氢氧化铵调节PH值6-7，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；
3)浸泡液的制备：荆芥8-10份，炒桔梗8-10份，蒸百部8-10份，蒸白前8-10份，蒸紫菀8-10份，梨皮5-8份，炒甘草3-5份，花茶4-5份；
将组成原料中的荆芥、炒桔梗、蒸百部、蒸白前、蒸紫菀、梨皮和炒甘草，放入蒸馏瓶中，加入5倍的清水，蒸煮，至蒸馏瓶中的水蒸干，收集水蒸气，水蒸气重新液化；同时将花茶放入开水中浸泡，水量为300ml，浸泡5-8分钟，过滤水，得到花茶水；再将收集的水蒸气与花茶水混合；
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；
再将纤维层浸泡在浸泡液中，加热，水温控制在60℃，浸泡10-11小时，取出晾干；
4)胶水的制备：MQ硅树脂5-9份、107硅橡胶2-5份、催化剂0.7-1份、增粘剂0.7-1份、200#溶解汽油2-4份；
将MQ硅树脂和107硅橡胶搅拌混合，同时加入催化剂，在90℃以上的高温下至完全混合；再将200#溶解汽油加入调节粘度，同时加入增粘剂，搅拌20分钟即可；
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。
本发明的有益效果是：本发明所采用的淀粉来源丰富、价格低廉，对环境友好；并且制得的无纺布强度高、生产成本低、可生物降解，能有效缓解白色污染问题，存放时间长，耐高温，耐水，延长使用寿命，减少白色污染，同时本身不含有任何甲醛等有害气体，并且通过浸泡液的浸泡，时刻散出药物成分，保证不对人体造成损害，保护环境。
