| titleOfInvention | Alkaline silica sol color fixing agent and preparation method thereof |
| abstract | The invention discloses a kind of alkaline silica sol color fixing agent and preparation method thereof, alkaline silica sol color fixing agent is with tetraethyl orthosilicate, water, alcohol, catalyst and silane coupler as raw material, according to mol ratio be 1: 30～40: 20～30: 0.3～0.7: 0.001～0.01 mix after, prepared by solgel reaction；Its preparation method is: tetraethyl orthosilicate and alcoholic solvent is mixed, stirs, be made into solution A；Water is mixed homogeneously with catalyst, is made into B solution；Take 30wt%A solution in reactor, it is warming up to 30～60 DEG C, under agitation the solution A of B solution and residue 70wt% is added drop-wise in reactor, with 30～60 DEG C of condensing refluxes, after reaction 30min, drip silane coupler again, continue stirring reaction 0.5～3h, be aged 8～12h, complete the preparation of alkaline silica sol color fixing agent, there is safety and environmental protection, colour fixation strong, the advantage such as silica sol granule particle diameter is little, narrow distribution. |
