| titleOfInvention | High-dispersity precipitated silica anti-settling agent for coating and preparation method thereof |
| abstract | The invention belongs to the technical field of precipitated silica, and particularly relates to a high-dispersity precipitated silica anti-settling agent for a coating and a preparation method thereof. The preparation method of the silicon dioxide anti-settling agent comprises the following steps: s1, liquefying solid sodium silicate at high temperature, adding water and ethanol to prepare a sodium silicate solution for later use; s2, adding a sodium silicate solution into a reaction kettle, heating, stirring and dropwise adding a sulfuric acid solution, controlling the pH value of the reaction end point, stopping adding acid, aging, performing pressure filtration, and washing to obtain a filter cake; s3, breaking the filter cake, putting the filter cake into a thick slurry tank, adding water to adjust the solid content of the thick slurry under stirring, then adding organic acid, uniformly stirring, spray-drying and crushing to obtain the high-dispersity precipitated silica anti-settling agent for the coating. The silicon dioxide anti-settling agent has excellent dispersibility in the oily polyester coating, can enhance the viscosity and thixotropy of a coating system, maintain the stability and no settling of materials in the system, and ensure the quality of the oily polyester coating and the coating quality. |
