| titleOfInvention | A kind of emulsion type defoamer and preparation method thereof |
| abstract | The invention provides an emulsion type defoamer and a preparation method thereof. The preparation method includes: preparing silica modified by γ-methacryloxypropyltrimethoxysilane and 3-aminopropyltrimethoxysilane; further preparing a silicon paste compound by using the modified silica; preparing Compound emulsifier; mix the silicon paste compound and compound emulsifier evenly. The present invention adopts SiO 2 modified by 3-aminopropyltrimethoxysilane and γ-methacryloyloxypropyltrimethoxysilane, which greatly improves the antifoaming performance of the defoaming agent. In addition, the obtained emulsion-type defoamer is not prone to delamination and oil drift, and has good dispersibility and storage stability; and under this emulsification condition, the defoamer has good defoaming performance and foam-inhibiting performance. |
