Description
技术领域
本发明涉及纺织化工技术领域,具体的讲是一种防黏辊的氟碳防水剂及其制备方法。
背景技术
氟碳织物三防整理剂是纺织后整理一类重要的整理剂,经氟碳织物三防整理剂整理过的织物具有拒水、拒油、拒污的三防效果。三防整理主要可应用于涤纶、涤棉、全棉等织物。在运动休闲服装及工作服、家具遮布、汽车内饰材料等方面应用广泛。然而在应用氟碳三防整理剂对织物加工整理过程中,经常出现粘辊问题,需要不断停机清理,不仅阻碍生产加工的连续性,也影响了生产质量。而出现这种情况的原因除了加工过程中的设备、加工面料的影响因素外,作主要的还是使用的氟碳整理剂的稳定性不够,加工过程中环境温度等变化,使得稳定剂破乳,从而产生了粘辊问题。
为此设计一种纺织品用不粘辊的氟碳防水剂是十分有必要的。
发明内容
本发明突破了现有技术的难题,设计了一种纺织品用不粘辊的氟碳防水剂,有效解决了纺织加工过程中出现的三防整理剂的粘辊现象。
为了达到上述目的,本发明设计了一种防黏辊的氟碳防水剂,其特征在于:所述氟碳防水剂由含佛丙烯酸酯聚合物乳液、相变蜡、乳化剂、PH值调节剂、水组成,各组分的质量百分比含量为: 10%~35%的含氟丙烯酸酯聚合物乳液, 10%~15%的相变蜡, 2%~3%的乳化剂, 1~3%的PH值调节剂,44%~77%的去离子水。
所述含氟丙烯酸酯聚合物乳液为六氟丙烯酸丁酯制备的聚合物乳液、八氟丙烯酸戊酯制备的聚合物乳液、C6防水剂、C8防水剂中的任意一种或几种。
所述相变蜡为35#相变蜡、RT31相变蜡、RT35相变蜡、ASTORPHASE30相变蜡、ASTORPHASE42相变蜡中的任意一种或几种。
所述乳化剂为HLB值在8-12中的聚氧乙烯型非离子表面活性剂中的一种或几种。
所述pH值调节剂为马来酸二酯化合物、氯乙酸乙酯化合物、草酸二甲酯化合物的一种或几种。
本发明还设计了一种防黏辊的氟碳防水剂的制备方法,其特征在于:按照如下步骤进行制备:
步骤1:按照权利要求1所述的配比称取相变蜡、乳化剂、含氟丙烯酸酯聚合物乳液和去离子水;
步骤2:将步骤1称取的相变蜡、乳化剂和去离子水加入容器混合,在温度范围为50℃~60℃的恒温水浴中熔化,搅拌均匀,保持乳化30min~50min,之后空冷至室温,获得相变蜡乳液;
步骤3:在步骤2获得的相变蜡乳液中边搅拌边加入步骤1称取的含氟丙烯酸酯聚合物乳液,获得混合乳液;
步骤4:在步骤3获得的混合乳液中加入PH值调节剂,混合均匀,获得防黏辊的氟碳防水剂。
所述防黏辊的氟碳防水剂在处理面料的工作液中的用量为20~60g/L,且面料浸轧工作液后的带液率为50%~80%,面料的烘干温度范围为95~98℃,烘干时间为2~4分钟,焙烘温度范围为160~170℃,时间为1~2分钟。
本发明与现有技术相比,在防水剂的配方中加入了相变蜡,保证在加工进行过程中保持工作液温度相对稳定,从而提高了工作液系统的稳定性,较现有的防水剂破乳概率降低,并且其中包含的PH值调节剂,在加工过程中可以缓慢释放酸,使得工作液使用保持在弱酸性,提高了防水剂的稳定性,避免了黏辊现象的发生。
