| titleOfInvention | A kind of silicone defoamer that can be used for water-based paint and preparation method thereof |
| abstract | The invention relates to an organosilicon defoamer that can be used for water-based coatings and a preparation method thereof. The method comprises the following steps: (1) synthesis of isomeric alcohol ether-terminated allyl polyether; (2) terminal isomeric alcohol ether-terminated Synthesis of polyether modified silicone oil; (3) Preparation of silicone paste; (4) Preparation of defoamer. The present invention uses anomeric alcohol ether-terminated polyether-modified polysiloxane with symmetrical structure, and simultaneously introduces hydrophilic eo segment, hydrophobic po segment and isomerized large segment on the end group of polysiloxane chain. The molecular alkyl alcohol ether group can effectively adjust the hydrophilicity and hydrophobicity of the polymer by controlling the ratio of eo to po, and achieve better defoaming performance. The organosilicon defoamer of the invention has easy-to-obtain raw materials, simple process and good stability, can effectively eliminate the foam of the water-based coating system, has excellent defoaming and foam-suppressing performance, is not easy to cause defects such as shrinkage cavities, and has good wetting performance at the same time. , which can save the amount of wetting agent in water-based coatings. |
