Rapid foam inhibitor

一种快速抑泡剂

Abstract

The invention discloses a rapid foam inhibitor. The rapid foam inhibitor comprises the following raw materials in percent by weight: 8 to 15 percent of trifluoropropyl modified silicon polyether, 5 to 10 percent of dimethyl silicon oil, 4 to 7 percent of hydroxyl silicon oil, 10 to 20 percent of high-boiling silicon oil, 7 to 12 percent of emulsifying agent, 2 to 4 percent of thickening agent and 42 to 55 percent of deionized water. The rapid foam inhibitor is prepared by adopting the trifluoropropyl modified silicon polyether, the dimethyl silicon oil, the hydroxyl silicon oil and the high-boiling silicon oil as main defoaming active components and adding the emulsifying agent, the thickening agent and the deionized water, and has the characteristics of small amount of use, fast defoaming, long foam inhibiting time, excellent dispersing performance and lasting defoaming, good stability, no toxicity and no odor and the like; due to the addition of the trifluoropropyl modified silicon polyether, not only can the defoaming active components be emulsified, but also the defoaming capability can be improved; due to addition of the silicon oil, the good and rapid effects of defoaming and foam inhibition can be obtained by reducing the surface tension; and the rapid foam inhibitor is strong in defoaming capability, and can be widely applied in the industries of paper making, printing ink, coating and chemical engineering and the like.
本发明公开了一种快速抑泡剂,按照质量百分比的原料包括三氟丙基改性硅聚醚8-15%、二甲基硅油5-10%、羟基硅油4-7%、高沸硅油10-20%、乳化剂7-12%、增稠剂2-4%、去离子水42-55%。本发明以三氟丙基改性硅聚醚、二甲基硅油、羟基硅油、高沸硅油为主要消泡活性成分,通过添加乳化剂、增稠剂和去离子水制得一种快速抑泡剂,具有用量少,消泡速度快,抑泡时间长,分散性能优异且消泡持久,稳定性好,无毒无味等特点;三氟丙基改性硅聚醚既可乳化消泡活性成分,还可以提高消泡能力;硅油通过降低表面张力,可以获得良好的、迅速的消泡和抑泡的效果;本发明消泡能力强,可广泛应用于造纸、油墨、涂料、化工等行业。
