Embodiment Construction

[0025] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the examples.

[0026] A preparation method of modified melamine resin essence microcapsules, comprising the steps of:

[0027] (1) Preparation of styrene-maleic anhydride copolymer powder

[0028] Dissolve styrene, maleic anhydride and initiator in a mixed solvent of aromatic hydrocarbons and ketones to prepare a mixed solution, wherein: the molar ratio of styrene to maleic anhydride is 1:1-5:1; in the mixed solution The mass percent of the aromatic hydrocarbon solvent is 10%-80%; the mass ratio of the ketone solvent to the maleic anhydride in the mixed solution is 0.5:1-3:1; the quality of the initiator accounts for 0.5-5% of the mixed solution; the aromatic The hydrocarbon solvent is an aromatic hydrocarbon solvent with 7-10 carbon atoms;

[0029] Add the mixed solution dropwise i...

Abstract

The invention discloses a preparation method for a modified melamine resin essence microcapsule. The preparation method comprises the following steps: (1) preparing styrene-maleic anhydride copolymerpowder; (2) preparing styrene-maleic anhydride copolymer solution; (3) preparing melamine resin prepolymer; (4) preparing the self-splicing double-wall essence microcapsule. Firstly, the styrene-maleic anhydride copolymer is taken as emulsifier, the essence is taken as a capsule core, the melamine resin and polyacrylate are taken as wall materials, and the essence is respectively encapsulated through an in-situ polymerization method and an interfacial polymerization method, and the melamine resin essence microcapsule is prepared. The essence microcapsule prepared with the method has a good coverage rate for the essence, and the stability of a product is good.

Description

technical field [0001] The invention belongs to the technical field of textile finishing, and specifically relates to a self-adhesive fabric with melamine resin and polyacrylate as the double-layer wall material and essence as the core material respectively formed by in-situ polymerization and interface polymerization. The preparation method of essence microcapsule. Background technique [0002] Microcapsule technology is a microcapsule technology that uses polymer materials to embed active substances to form semi-permeable or sealed capsules. It can improve the physical properties of the encapsulated substance, isolate the active ingredient from the external environment, enhance stability, reduce volatility, prolong shelf life, and also have a controlled release function. [0003] Textiles with aromatic smell are deeply loved by consumers. However, the composition of essence is very complex. The ingredients contained in it are mostly volatile and chemically unstable subs...
