Disperse dyestuff microcapsule and preparation method thereof

The invention belongs to the technical field of microcapsules, and in particular relates to a disperse dyestuff microcapsule and a preparation method thereof. The method provided by the invention firstly takes a fine-particle disperse dyestuff as a core material and takes melamine resin obtained by taking melamine and formaldehyde to react as a wall material to prepare the disperse dyestuff microcapsule; then the wall material melamine resin is subjected to silazane treatment to remove hydroxyl on the melamine resin, and the melamine resin wall material is further sealed, so that a condition that the dyestuff of the disperse dyestuff microcapsule in a solvent is leaked is avoided and the solvent resistance of the dyestuff microcapsule is enhanced. The method has the advantages of no pollution, few auxiliary agents, low cost and convenience for operation, and the obtained dyestuff microcapsule has high stability. 本发明属于微胶囊技术领域，具体涉及种分散染料微胶囊及其制备方法。该方法中首先以细颗粒分散染料为芯材，以三聚氰胺和甲醛反应而得的密胺树脂为壁材制备分散染料微胶囊，然后对壁材密胺树脂进行硅氮烷处理，脱
