Abstract
The present invention provides a kind of preparations of Nano capsule essence, the preparation step including wall material, core material, Nano capsule essence.On traditional liquid essence surface, by the polymerization reaction of acrylate and styrene copolymer latexes, acrylic acid, melamine methylol resin, polymer overmold essence is formed, and then obtains Nano capsule essence, and by secondary embedding, stable Nano capsule essence is obtained.
Description
Technical field
The present invention relates to a kind of preparation of Nano capsule essence, in particular to by traditional liquid essence, coated by wall material,
Form a kind of Nano capsule essence.
Background technique
Essence is widely used in the fields such as food, cosmetics, detergent, textile, papermaking.However traditional liquid essence
Have the characteristics that rate of release is fast, action time is short, and some fragrance components in essence to environmental conditions such as light, heat, oxygen very
Sensitivity, easily because extraneous effect causes fragrance loss.Therefore, preparation is convenient to use, stable storing, can meet different sustained releases and wants
The fragrance product asked is the important development direction in spices and essence field.
Nanotechnology is the one developed in recent years research and probe electronics in nano-scale range, atom and divides
The novel high-tech subject of the sub- characteristics of motion and characteristic is increasingly subject in the application of biomedical, pharmacy and material science
The attention of people.Wherein, Nano capsule is a kind of partial size in nanoscale, small with unique physico-chemical and biological activity
Particle.Active component receive micropackaging, there is the dissolubility for improving hydrophobic components, prevent external environment to active component
Interference and destruction, extend volatile components release time, control many potentiality such as medicament slow release and targeting NO release.Cause
This encapsulates spices and essence by encapsulation techniques, can be effectively protected work in view of the above-mentioned superior function of Nano capsule
Property component, improve the stability of object of being embedded, and slow down the rate of release of fragrance, extend its release time.Therefore, novel essence
Nano capsule development is to solve traditional essence important method of problems at present.
Summary of the invention
The technical problem to be solved by the present invention is to by being formed poly- on traditional liquid essence surface by polymerization reaction
It closes object and coats essence, and then obtain Nano capsule essence, and by secondary embedding, obtain stable Nano capsule essence.
The purpose of the present invention with following technical proposals by being realized:
9 grams of acrylate and styrene copolymer latexes, 9 grams of acrylic acid are weighed, 200 grams of deionized waters are dissolved in, open stirring,
Adjusting pH value with sodium hydroxide solution is 3.5.7 grams of melamine methylol resins are added.It stirs evenly, 180 grams of liquid is added
Essence opens homogenizer, and is warming up to 60 DEG C, obtains stable essence lotion, continues to stir.Weigh again 10 grams of acrylate and
120 grams of water are added in styrene copolymer latexes, and adjusting pH value with sodium hydroxide solution is 5, add 30 grams of methylol melamines
Polyimide resin stirs evenly, and is added in the essence lotion of aforementioned stable, homogeneous, and is warming up to 75 DEG C, and homogeneous stirs and to react 7 small
When, just obtain Nano capsule essence.
Liquid essence of the present invention includes daily chemical essence and edible essence, including bouquet type composition such as rose, jasmine,
The lily of the valley, violet, tuberose, lilac etc. also include Fruity type essence such as apple, sweet orange, pineapple, strawberry, lemon, tangerine
Son, banana etc. also include the essence of other odor types such as compound bouquet type composition and radix aucklandiae, cream perfume, milk.
Beneficial effects of the present invention：The present invention forms polymer overmold essence by polymerization reaction, and then obtains nanometre glue
Capsule essence, and by secondary embedding, stable Nano capsule essence is obtained, reaction condition of the present invention is mild, and preparation process is simple.
Through transmissioning electric mirror test（See attached drawing 1）, prepared about 100 nm of Nano capsule essence partial size or so, rounded bulbous obtains
Nano capsule essence have many advantages, such as that fragrance slow release and fragrance remaining time are long.
Detailed description of the invention
