聚酰胺俗称尼龙(PA),居五大通用工程塑料之首。尼龙具有优异的机械强度高、韧性好、高熔点、耐磨、耐油和耐一般有机溶剂,且耐热性能优良,因此在日常生活和工业领域的应用十分广泛。
MMT是一类非金属矿物的硅酸盐,具有层状结构。MMT单个片层的厚度为l nm,宽度约为100nm,是一种高度有序的准二维晶片。具有高刚度,层间不易滑移的特点。MMT比表面积较小,影响了吸附性能,其层间距较小,且层间化学微环境为亲水憎油性,需要对MMT进行针对性的改性,制得纳米复合材料。 采用原位插层聚合方法制备尼龙6/蒙脱土(PA6/MMT)复合材料优势明显:
(1)MMT用量极少,即可大大提高复合材料强度、弹性模量、韧性及阻隔性能,聚合物/MMT纳米复合材料比传统的聚合物体系密度小,各项热力学综合性能优异,成本也有一定程度下降。
(2)聚合物/MMT纳米复合材料热稳定性及尺寸稳定性优良。
(3)MMT片层可以在二维方向上起到增强作用,纳米复合材料的力学性能有望优于纤维增强聚合物体系。
(4)由于MMT片层呈平面取向,且以纳米尺度分散在聚合物基体中。原位聚合的尼龙6/蒙脱土复合材料具有高耐热性、高强度、高模量、高气体阻隔性能、低吸水性和优良的加工性能,大大拓展了复合材料的应用领域,PA6可广泛应用于汽车、船舶、电子电器、工业机械和日用消费品、食品包装、医药等领域。
该材料已采用五层下吹水冷吹塑薄膜生产线在投产。
一、原位插层聚合蒙脱土改性PA6 将Na-MMT、ε-己内酰胺、催化剂、助催化剂、活性剂和水混合均匀,形成稳定的胶体分散体系,结合以前所做的工作,使分散体系在机械搅拌和超声波振荡作用下,混合分散均匀,放入自制聚合釜中聚合。使离子交换、单体插层、单体原位聚合一步完成,不但缩短了工艺流程,降低了成本,还提高了产品性能。 将反应温度设定在聚合物熔点以下,提高了聚合物白度,解决了聚合产物易变黄发黑的问题,实现了低温一步法制备纳米复合材料的最佳工艺条件,在此工艺条件下通过原位插层法制备了PA6/MMT纳米复合材料,分析表明复合材料分子量很高,PA6分子链进入MMT层间,MMT层间距大大增加,大大提高了材料的热力学性能和白度。

                                                                                    


二、原位插层聚合PA6/复合蒙脱土高阻隔性材料 将蒙脱土经一次无机改性和两次有机改性,制备大层间距复合蒙脱土,将复合蒙脱土和己内酰胺在聚合釜中聚合,通过控制催化剂等助剂和工艺调整产物分子量,制备力学性能优异的高阻隔性PA6/蒙脱土复合材料,可作为食品包装膜使用。
