Description

一种纺织印染用消泡剂的制备方法
技术领域
本发明属于消泡剂技术领域，特别涉及一种纺织印染用消泡剂的制备方法。
背景技术
在油气开采、制浆造纸、纺织印染、生物发酵、污水处理、涂料加工和建筑工业等领域，搅拌产生的泡沫会引起产能下降、反应周期延长和原料浪费等问题。添加消泡剂可在短时间内消除泡沫。消泡剂可以分为矿物油消泡剂、聚醚类消泡剂和有机硅消泡剂等。矿物油消泡剂只能在液体剪切力较小、所含表面活性剂发泡能力较温和的条件下使用，对致密型泡沫的消除能力较差。
聚醚类消泡剂只有当发泡体系的温度超过浊点温度时才能发挥消泡作用。近年来，有机硅类消泡剂因消泡效率高、用量少、无生理毒性而受到广泛关注，但有机硅分散性差，难以乳化，易凝聚成没有消泡活性的、粒度过大的油珠，而纯硅油对水溶液的泡沫无消泡作用。
发明内容
本发明为了解决上述问题，提供一种纺织印染用消泡剂的制备方法。
本发明采用以下技术方案来实现：
一种纺织印染用消泡剂的制备方法，包括如下步骤：
S1，将聚硅氧烷、高碳醇、硬脂酸锌、磷酸三丁酯、单甘油脂肪酸酯、过硫酸氢钾混合后，搅拌均匀，制得A液；
S2，将六偏磷酸钠、表面活性剂和增稠剂加入去离子水中，搅拌均匀制得B液；
S3，将A液和B液在60～70℃条件下混合，升温至90～100℃搅拌均匀后，加入疏水性二氧化硅和杀菌剂，保温30～40min，制得纺织印染用消泡剂。
优选的方案，步骤S3中，升温至90～100℃搅拌均匀后，除了加入疏水性二氧化硅和杀菌剂外，还加入了纺织印染用消泡剂。
优选的方案，所述聚硅氧烷为聚二甲基硅氧烷、聚甲基三乙氧基硅烷或聚甲基三甲氧基硅烷中。
优选的方案，所述表面活性剂为脂肪酸山梨坦、聚山梨酯、聚氧乙烯单硬脂酸酯或甘油脂肪酸酯。
优选的方案，所述增稠剂为羧甲基纤维素、羧乙基纤维素、黄原胶或聚丙烯酸酯。
优选的方案，所述杀菌剂为戊二醛或纳米氧化银。
本发明的有益效果是：
1.本发明制备的纺织印染用消泡剂，保证了消泡剂整体的消泡、抑泡效果，添加的助剂成分不仅能有效促进主要活性成分效果的发挥，同时又能改善整体长期存放发生粘度变大、出现交联倾向等失效的情况发生，提高了存储、使用时品质的稳定性。最终在各成分的共同配合作用下，本发明制得的纺织印染用消泡剂具有良好的消泡、抑泡特性，且长期储存使用的品质稳定，有很好的使用价值。
2、本发明的纺织印染用消泡剂中添加有疏水性二氧化硅、纳米氧化银和纳米氧化锌等物质，相互配合作用，可以作为消泡核心，起到快速消泡的作用。
