| Zusammenfassung: | The invention discloses a high-efficiency antifoaming agent. The high-efficiency antifoaming agent is prepared from low-hydrogen silicone oil, n-amyl alcohol, white carbon black, malonic acid, amino silicon oil, 1.5% concentrated sulfuric acid, octamethylcyclotetrasiloxane, trifluoropropionic acid, polyether silicone oil, carboxymethyl cellulose sodium, and sorbitol. According to a preparation method, low-hydrogen silicone oil is subjected to chemical modification so as to obtain the high-efficiency antifoaming agent, defoaming speed of the high-efficiency antifoaming agent is increased greatly, foam inhibition performance is improved, using amount is one third less than that of common antifoaming agents, and the high-efficiency antifoaming agent possesses excellent water solubility. |
