| titleOfInvention | A kind of double-core microcapsules and preparation method thereof and application |
| abstract | The invention discloses a kind of double-core microcapsules and preparation method thereof and application; During preparation, melamine and formalin are uniformly mixed, regulation system pH value is 8 ~ 9, is heated by melamino-formaldehyde mixed solution and stirs, adding and distilled water, be obtained by reacting watersoluble melamine-formaldehyde prepolymer in 65 ~ 70 DEG C of water-baths; Then by described carbamide performed polymer and emulsifying agent example mix and blend until all dissolve, adjust ph, adds the first core, is obtained by reacting the melamine formaldehyde resin microcapsules that particle diameter is 0.1 ~ 300 μm; Melamine formaldehyde resin microcapsules and the second core are added in chitosan solution, forms drop with syringe pump, be collected in CaCln 2 in solution, solidification 0.5h ~ 3h; It is spherical for obtaining profile, and particle diameter is the double-core microcapsules of 0.1 ~ 1000 μm.Double-core microcapsules of the present invention significantly can reduce the rate of release of active core, interact little between core. |
