Problems solved by technology

At present, the preparation of essential oil microcapsules by spray drying is a relatively common method, but due to the high temperature of spray drying, it is easy to cause the volatilization loss of aroma components, thereby reducing the utilization rate of essential oils.
In addition, most of the microcapsule wall materials prepared by this method are rigid and cannot be directly attached to the surface of the fabric, and still need to be fixed on the surface of the substrate by forming a film with an adhesive.

Embodiment 1

[0044] (1) Synthesis of adhesive latex.

[0045] In this embodiment, the selected structure of the macromolecular trithiocarbonate compound is shown in formula I, wherein, A is shown in formula III, B is shown in formula V, X=3, Y=70.

[0046] According to the formula in Table 1, the sodium lauryl sulfate aqueous solution and the macromolecular trithiocarbonate compound are mixed and stirred to a homogeneous phase to obtain a water system mixed solution; the lavender essential oil, styrene and n-hexadecane are mixed and stirred to a homogeneous phase to obtain a mixed liquid of the oil system. The water, oil system mixture and deionized water are mixed and stirred again, the purpose is to make them fully mixed and uniform to form an initial emulsified dispersion. The initial emulsified dispersion was placed in an ice bath and ultrasonically prepared to obtain a fine emulsified dispersion. Transfer the resulting fine emulsified dispersion to a four-necked flask under a nitrog...

Abstract

The invention provides aromatic adhesive latex film with controllable rigidity and softness and a preparation method thereof. The aromatic adhesive latex film is made from, by weight, 2-3.5 parts of essential oil, 8-14 parts of rigid monomers, 16-22 parts of soft monomers, 0.5-3 parts of a macromolecular trithiocarbonate compound, 45-50 parts of 3-6% by weight emulsifier solution, 1.5-3 parts of aco-emulsifier, 1.5-3.0 parts of 0.5-0.8% by weight initiator solution, and 9-19 parts of deionized water. The essential oil is microencapsulated so that volatilizing rate of the essential oil can besignificantly decreased; long-acting slow-release effect of the aromatic ingredients is evident. A triblock polymer synthesized by means of RAFT (reversible addition-fragmentation chain transfer) active polymerization has controllable molecular weight; the aromatic adhesive latex film has adjustable mechanical properties and is applicable to more fabric bases.

Description

[0001] (1) Technical field [0002] The invention relates to an aromatic adhesive latex film with controllable softness and strength and a preparation method thereof. [0003] (2) Background technology [0004] Essential oil is a volatile aromatic substance extracted from the flowers, leaves, stems, roots or fruits of plants. It itself has the functions of preventing infectious diseases, anti-bacteria, viruses, molds, anti-inflammation, anti-spasm, promoting cell metabolism and cell regeneration, and even some essential oils can regulate endocrine organs, promote hormone secretion, and let the human body Physiological and psychological activities have been well developed. It is precisely because of these excellent properties that essential oils are used in the aromatic finishing of high-end textiles, and can also impart health benefits such as fabric physiotherapy. [0005] At the same time, essential oils are extremely volatile and will evaporate quickly once exposed to air....
