无硅消泡粉及其制备方法

By preparing a silicone-free defoaming powder, utilizing the network structure polymer of polyether resin and higher alcohols, as well as alkyl glycosides, the problems of low defoaming efficiency, poor foam suppression effect, and water pollution caused by existing defoamers in wastewater treatment are solved. It achieves high-temperature and alkali-resistant defoaming effects, improving the efficiency and environmental friendliness of wastewater treatment.

Abstract

本发明提供了一种无硅消泡粉及其制备方法。以重量份数计，无硅消泡粉的制备原料包括60～90份填充粉料、1～25份乳化剂、5～30份助剂和10～40份消泡活性成分。消泡活性成分包括重量比为1:1～2:1的聚醚树脂和高碳醇。聚醚树脂为乙烯基树脂和丙三醇嵌段聚醚反应而得的聚合物。高碳醇的碳数至少为14，助剂至少包括烷基糖苷和抗结剂。该无硅消泡剂中不含硅，可避免引入硅而导致水体污染，此消泡粉消泡快抑泡持久，且还耐高温及耐碱。
