Description
技术领域technical field
本发明涉及消泡技术领域，具体而言涉及一种有机硅消泡剂及其制备方法。The invention relates to the technical field of defoaming, in particular to a silicone defoaming agent and a preparation method thereof.
背景技术Background technique
多数工业生产过程中，大量产生的气泡会影响生产效率、产品质量或导致设备损坏，因此消泡剂广泛应用于纺织、造纸、石油、食品、污水处理、制药等各个领域，在造纸行业中，泡沫会导致生产的不正常和纸张出现纸病，甚至断纸，大大降低纸机的工作效率和出纸质量，延误劳动时间造成损失。使用消泡剂是工业中消除有害泡沫有效手段之一。有机硅消泡剂具有表机张力低，化学稳定性、耐热性好，用量少等特点，能适应弱酸、碱、盐及高温体系的消泡。传统技术中的二甲基硅油就具有很高的消泡性能，但其在高温白水中因乳化不完全，易出现破乳漂油现象，同时二甲基硅油消泡剂抑泡能力较差。因此，对其做出配方改进，使有机硅类消泡剂通过合理改性并优化生产工艺以提高其自乳化能力及高温稳定性。In most industrial production processes, a large number of air bubbles will affect production efficiency, product quality or cause equipment damage. Therefore, defoamers are widely used in various fields such as textiles, papermaking, petroleum, food, sewage treatment, pharmaceuticals, etc. In the papermaking industry, Foam will lead to abnormal production and paper defects, or even paper breaks, which will greatly reduce the working efficiency of the paper machine and the quality of paper output, and delay labor time and cause losses. The use of defoamers is one of the effective means of eliminating harmful foam in industry. Silicone defoamer has the characteristics of low mechanical tension, good chemical stability, heat resistance, and less dosage, and can adapt to the defoaming of weak acid, alkali, salt and high temperature systems. Simethicone in traditional technology has high defoaming performance, but it is prone to demulsification and floating oil phenomenon due to incomplete emulsification in high-temperature white water, and simethicone defoamer has poor antifoaming ability. Therefore, it is necessary to make formulation improvements to improve the self-emulsifying ability and high temperature stability of silicone defoamers through reasonable modification and optimization of the production process.
