Description
本发明涉及一种高浓缩粉末固体消泡剂及其制备方法,确切地说,是一种应用于非离子表面活性剂中的固体消泡剂,消泡剂属于精细化工制剂,因此本发明隶属于精细化工制剂技术领域。
在日化、造纸、纺织印染、水处理、食品加工、石油化工等诸多行业中,不可避免地产生过多的泡沫,严重影响工业生产,如降低生产能力、影响产品质量、影响生产的正常进行等。因此在这些水性体系中,需要控制或防止泡沫的产生,而消泡剂成为一种必不可少的添加剂。
消泡剂按形态可分为固体和液体两种,液体消泡剂应用领域较广,但某些应用领域内,固体消泡剂有着液体消泡剂无法取代的地位。
目前公开已知的技术文献资料涉及固体消泡剂的制备方法有很多:专利CN101721843A介绍了一种固体颗粒抑泡剂的制备方法,将主要消泡物质和乳化剂混合后,再和有机载体混合,加入结构剂和水搅拌均匀,造粒,烘干。专利CN101991976B介绍了一种固体消泡剂的制备方法,将消泡活性物、乳化剂和结构剂先混合,依次加入有机载体和去离子水混合,造粒后烘干。CN102302869B介绍了一种固体颗粒抑泡剂的制备方法,将主要消泡物质和乳化剂先混合,然后吸附到载体上,再加入结构剂,造粒,干燥。CN102407033B介绍了一种颗粒消泡剂的制备方法,采用有机硅乳液来代替硅脂,并将有机硅乳 液分步附聚到载体上,形成两个硅脂“层面”,最后将混合物造粒,烘干。CN111821722A提供了一种用于气井泡沫排水采气的纳米固体消泡剂,将固化剂加热熔化与乳化剂混合,然后与二甲基硅油和改性二氧化硅纳米颗粒搅拌混合得到。上述专利制备的固体消泡剂活性物含量不超过30%,其虽然具有一定消抑泡性能,但是在体系中的添加量较高,不经济,可能会对应用体系产生副作用。
CN111389057A介绍了一种活性物含量高的有机硅消泡剂的制备方法,通过加入羧甲基纤维素钠提高该乳化助剂的乳化效果,另外在该消泡剂的制备的成型工序中加入固化剂,既能延长消泡剂的使用期限,也将固体消泡剂活性物含量提高至60%。但是产品的固化效果有待进一步提高,长时间放置产品会发生吸潮结块,从而影响产品的使用。

固体消泡剂性能测试
消抑泡性能测试
洗衣机测试
测试方法:在容量为7kg的滚筒洗衣机里加入50g市售的洗衣粉,0.3g固体消泡剂,测试程序为标准洗。洗衣机的门上标有11个度量表示,依次记为0,10,20,……100,其中0为起始,表示无泡沫;100表示 充满泡沫。每5min为一个洗涤周期,每5min记录一次泡沫高度,且在停机时记录数据。数值越大,表明洗衣机中的泡沫高度越高,抑泡效果就越差;相同时间内泡沫高度越低,说明产品抑泡性能越好。测试结果如下:
表1洗衣机测试结果
无限制压缩测试(UCT)
测试方法:将消泡剂粉末压缩成压紧物,并测量使该压紧物破裂所需的力。将粉末填充进入机筒中并使表面水平。将50g塑料圆盘放置在粉末顶部上,将10kg加重柱塞缓慢放置在圆盘顶部上,并使其保持就位2分钟。然后除去砝码和柱塞,并将粉末除去机筒,保留在其顶 部具有50g塑料圆盘放置在第一个圆盘顶部,并保留大约十秒。然后如果压紧物仍然未破坏,将向塑料圆盘增加100g圆盘,并保留十秒。然后以十秒间隔,250g增量增强负重,直到压紧物崩溃。记录引起崩溃所需的总重量(w)。
消泡剂粉末的内聚性如下按重量(w)分类:
1、良好流动
2、适度流动
3、有内聚力
4、非常有内聚力
