| titleOfInvention | A kind of preparation method of narrow dispersion large particle size silica sol |
| abstract | A preparation method of narrowly dispersed large particle size silica sol, the preparation is carried out according to the following steps: (1) mixing low molecular weight alcohol and pure water, heating at a constant temperature of 80 ° C in an oil bath, and stirring mechanically for 30 minutes; (2) mixing the obtained Add an alkali catalyst into the solution; (3) dropwise add the silicon source precursor solution and the surface modifier solution into the solution, and continue mechanical stirring at a constant temperature of 80°C; (4) concentrate to the required solid content, thereby obtaining a narrowly dispersed large particle Diameter silica sol products. Compared with the traditional silica sol, the silica sol prepared by the present invention has the advantages of large particle size, concentrated particle size distribution, high sphericity, good stability, etc., and can be better applied to technical fields such as optical film coating liquid. |
