一种聚氨酯润滑剂及其制备方法和用途
技术领域
本发明公开了一种聚氨酯润滑剂及其制备方法和用途,该润滑剂是由异氰酸酯和含有单官能度活泼氢基团的脂肪族化合物反应制得,具有与聚氨酯相容性优异、不析出、防粘和润滑效果突出的特点。
背景技术
聚氨酯是指在大分子主链中含有氨基甲酸酯基的聚合物,一般聚氨酯包含聚酯型和聚醚型,具有较高的机械强度、柔韧性、弹性、耐磨性、耐油性等性能优异,市场应用广泛。
由于聚氨酯分子结构中存在强极性基团和聚酯或者聚醚柔性链段结构,聚氨酯材料的粘性较强,对某些市场应用具有不良的影响。例如,聚氨酯弹性体在注塑、压延等加工成型过程中粘连模具,脱模困难;聚氨酯卷材或薄膜收卷后不易开口的问题;浇注型聚氨酯弹性体和聚氨酯发泡材料在成型过程中脱模困难。
CN105504222 A公开了一种高透明手机壳护套专用TPU材料及其制备方法,为实现热塑性聚氨酯弹性体的良好脱模,添加了0.1~0.6%的润滑剂,润滑剂为硬脂酸酰胺、蒙旦蜡、油酸酰胺或乙撑双硬脂酸酰胺中的一种或几种的混合物。US3595827公开了一种自润滑组合物,其中润滑剂结构为R1-CONH-R2化合物,添加量为0.02~1%。US3562291公开了一种芥酸酰胺和月桂酸酰胺的组合物用于聚合物的防粘和自润滑。以上针对聚烯烃的酰胺类或者蒙坦蜡类的润滑剂在用于聚氨酯时,存在相容性差,析出,喷霜出油的问题,产品品质尤其是外观品质受到较大的影响。

实施例和对比例应用验证
以市场上广泛销售的乙撑双硬脂酸酰胺(EBS常州可赛),芥酸酰胺(英国CrodaER),硬脂酸钙(三益SAK-CS-P),蒙坦蜡(Clariant E)作为对比实施例使用双螺杆挤出机加入至常见市售90A TPU(BASF Elastollan 690A)中,测试TPU的脱模力,剥离力,试片透明性,表面析出等。使用本专利所述的一种聚氨酯润滑剂,作为实施例,采用同样的方法将润滑剂加入至常见市售90A TPU(BASF Elastollan 690A)中。具体实施方案如下:
将实施例和对比例的润滑剂按照表1的配方和TPU进行充分混合,然后在南京杰亚挤出装备有限公司的SHJ-42双螺杆挤出机中进行高速剪切混合造粒,螺杆的各区温度设置分别为:一区温度:180℃,二区温度为195℃,三区温度为210℃,四区温度为210℃,五区温度为205℃,六区温度为200℃,七区温度为200℃,八区温度为195℃,九区温度为190℃,口模温度为190℃。喂料速度设置为35转/分,螺杆转速设定为300转/分。
性能对比如下表。
Figure BDA0001882316070000061
Figure BDA0001882316070000071
注*1:使用市售的TPU(BASF Elastollan 690A),使用注塑机(克劳斯马菲CX80-180)和2mm平整模具,测试注射件从模具上顶出时的力。
注*2:使用市售的TPU(BASF Elastollan 690A),使用流延机成型0.2mm薄膜,收卷后测试开口剥离力。参照标准为:ASTM-D3330-a。
注*3:使用市售的TPU(BASF Elastollan 690A),使用注塑机(海天M600A型)注塑成2mm试片,模具粗糙度在0.02以下。在70℃烘箱中放置48h,测试样片表面是否脏污,若有明显脏污,则记录光泽度是否洁净,有无析出物。如有明显异物则记录为“有析出”或者“严重析出”;如表面洁净,则测试透光率,测试光泽度的仪器为英国Diffison,EEL-57D,测试参照标准为ASTM D1003。
通过以上试验测试与对比例进行比较可以看出,相比与常规的防粘脱模助剂,使用本专利所述的聚氨酯润滑剂具有防粘效果好,不析出,不影响聚氨酯产品透明性等优点,是聚氨酯润滑、防粘助剂的产业方向,极具市场价值。
以上所述具体实施例是对本发明精神所做的举例说明,并不用于限制本发明,凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等,均应包含在本发明的保护范围之内。
