Abstract

The invention provides a preparation method of an intelligent controlled release essence capsule with an ambient temperature response function. The preparation method comprises the following steps: (1) fully stirring and dissolving (methyl) alkyl acrylate monomers with different alkyl chain lengths, an oil-soluble initiator and essence to prepare a homogeneous oil phase; (2) adding the prepared organic oil into an aqueous solution containing an emulsifier for full stirring and shearing emulsification to obtain emulsified drops with the particle size of 10nm-5mm; (3) heating emulsion to generate polymerization reaction by the (methyl) alkyl acrylate monomers to form essence-wrapped capsule wall, and performing filtering and washing to obtain the essence capsule with a nuclear shell structure. The synthesis technology is simple, and the energy consumption is low; the requirement on equipment is low, and reaction conditions are easy to control; the preparation method has a large-scale production prospect. The capsule capable of intelligently adjusting the release speed has a great application prospect in the field of cosmetics and the field of intelligent heat storage and temperature adjustment textiles.

Description

technical field

[0001] The invention relates to a method for preparing an essence capsule, in particular to a method for preparing an intelligently controlled release essence capsule with an environmental temperature response function. Background technique

[0002] Encapsulation technology is used to wrap the essence to make aromatic capsules with a particle size of 10nm~5mm, which avoids direct contact between the essence and the outside world, thereby achieving the purpose of inhibiting the essence from volatilizing too quickly and controlling the release speed of the essence. In addition, aroma capsules can avoid the "burst effect" and prolong the duration of fragrance. Fragrance capsules are widely used in the textile industry and also in daily cosmetics. At present, some people have prepared aromatic microcapsules with melamine-formaldehyde resin as the capsule wall by in-situ polymerization. This method has simple preparation process and low cost, but formaldehyde wil...
