| titleOfInvention | Uniform silica microsphere, preparation method therefor, and application thereof |
| abstract | Provided are a uniform silica microsphere, a preparation method therefor, and an application thereof. The method comprises the following steps: (1) mixing an organosilicon compound and an aqueous medium according to a certain ratio to obtain an organosilicon compound/H 2 O emulsion; (2) adding a small molecule alcohol or mixed small-molecule alcohol solution to the organosilicon compound/H 2 O emulsion of step (1), to obtain a transparent organosilicon compound/alcohol-H 2 O mixture; (3) adding a catalyst to the organosilicon compound/alcohol-H 2 O mixture of step (2) to conduct a hydrolytic polycondensation reaction, turning the transparent organosilicon compound/alcohol-H 2 O mixture into a milky-white silica sol; and (4) subjecting the silica sol of step (3) to centrifugal separation to obtain the uniform silica microspheres. The method uses an aqueous medium as a solvent, and features a simple and controllable process, mild conditions, a uniform and controllable particle size, and large batches of reaction, and can overcome various disadvantages in the prior art and has wide application prospects. |
