| titleOfInvention | Fluorescent thermal expansion microcapsule and preparation method and application thereof |
| abstract | The invention relates to the technical field of thermal expansion microcapsules, and particularly discloses a fluorescent thermal expansion microcapsule as well as a preparation method and application thereof. The microcapsule comprises a capsule core and a capsule wall, wherein the capsule core is a low-boiling-point alkane foaming agent, and the capsule wall sequentially comprises a cross-linked polyurea buffer layer, a fluorescent agent-acrylate copolymer composite layer and an interpenetrating network cross-linked acrylate copolymer protective layer from inside to outside. The preparation method comprises the following steps: the polyurea is used for coating the inner shell layer of the low-boiling-point alkane foaming agent by an emulsion template method through interfacial polycondensation, and then the surface of the polyurea inner shell layer is coated with a middle layer of a fluorescent agent-acrylate copolymer and an interpenetrating network crosslinked acrylate copolymer outer protective shell layer by surface free radical polymerization by using an emulsion template self-assembly technology. When the thermal expansion microcapsule is applied to ink printed matters, the thermal expansion microcapsule can generate two functions of 3D stereoscopic vision/touch effect and fluorescence indication, and is very suitable for the fields of anti-counterfeiting materials, special markers, fluorescent road signs and the like. |
