| titleOfInvention | Composite defoaming agent and preparation method thereof |
| abstract | The present invention provides a composite antifoaming agent and a preparation method thereof, comprising: 1) mixing stearic acid and an antioxidant to a temperature of 80-100 ° C until the stearic acid is melted to obtain a mixed liquid X1; After adding ethylenediamine and the first catalyst to the mixture X1, the mixture is stirred and mixed at a temperature of 140-150 ° C for 3-5 hours to obtain a base Y1; 2) in the presence of the second catalyst, and the temperature is 80- The base material Y2 is prepared by mixing a hydrogen-containing silicone oil and an allyl polyoxyethylene polyoxypropylene ether at 100 ° C; 3) placing the silica and the dimethyl silicone oil in the presence of the third catalyst The mixture is mixed for 4-6 hours at a temperature of 150-180 ° C to obtain a base Y3; 4) The base Y1, the base Y2, the base Y3 and water are mixed and emulsified to obtain a composite antifoaming agent. The invention has the advantages of simple preparation, mild conditions, good defoaming and foam suppression performance, and can be applied to various foam types. |
