| titleOfInvention | A kind of preparation method of water-soluble polystyrene-silicon dioxide core-shell type composite particle |
| abstract | The present invention relates to the preparation method of a kind of polystyrene-silica core shell mould composite particles, for: (1) preparation is through the aqueous solution of the granules of polystyrene of tensio-active agent surface modification; (2) preparation linking agent and silicon aqueous acid, regulates its pH value to be alkalescence by pH adjusting agent, the obtained alkaline aqueous solution through the silicic acid of linking agent process; (3) aqueous solution of the granules of polystyrene through tensio-active agent surface modification that regulating step (1) is obtained is alkalescence, under mechanical stirring heating condition, dropwise drip the alkaline aqueous solution of the obtained silicic acid through linking agent process of step (2), carry out polyreaction; (4) after reaction terminates, stop heating, continuation stirring is cooled to room temperature and obtains described polystyrene-silica core shell mould composite particles; This preparation method has feature with low cost, to be easy to production. |
