Problems solved by technology

However, when the capsule is applied to fabrics, its essence content drops by 2 / 3 after 6 months, and there is basically no fragrance after one year, while general clothing, interior wall paint and other products need to be used for 5-10 years, so the long-term use of the capsule The effect of lasting fragrance still needs to be strengthened

preparation example Construction

[0027] A preparation method of microcapsules with fragrance sustained-release function, characterized in that it comprises the following steps:

[0028] A. Emulsion preparation: Weigh a certain amount of gelatin and gum arabic into a beaker, add a certain amount of distilled water respectively, and dissolve them fully in a water bath at 40°C, then mix the two solutions evenly, and add nanoscale calcined shells Powder, use a high-speed disperser to disperse at a high speed of 2.5 minutes at 4000rpm, then add a certain amount of nourishing and tranquilizing functional essence, and continue to emulsify at 10000rpm for 7 minutes to form a uniform emulsion;

[0029] B. Complex coacervation reaction: use the method of adjusting the pH value; pour the emulsion into a three-necked bottle, add distilled water to dilute to the required concentration, stir at 40°C and add 10% acetic acid solution dropwise to adjust the pH of the system to 3.8. Coagulate the gelatin and gum arabic, keep t...

Abstract

The invention discloses a method for preparing a microcapsule having a slow fragrance release function. According to the method, essence having a function of tranquilizing the mind by nourishing the heart is subjected to dual coating through shell powder and a microcapsule to obtain the microcapsule having the fragrance slow release function. The preparation method is simple, and active ingredients of fragrance can be released slowly continuously. When the microcapsule is applied to internal wall coating, the microcapsule not only makes it aromatic durably indoors, but also has a function of tranquilizing the mind by nourishing the heart, and has effects of relieving mental fatigue and improving sleep.

Description

technical field [0001] The invention relates to the technical field of fine chemicals, in particular to a preparation method of microcapsules with fragrance slow-release function. Background technique [0002] In recent years, the rapid development of microcapsule technology has led to the technological innovation of textiles, coatings and other products in terms of functionality, fashion, and advancement. Fragrance can not only make people have beautiful reverie, but also has a variety of medical and health care effects. The use of microcapsules to provide micro-containers can protect the fragrance from volatilization and prevent the oxidation and pollution of the fragrance. [0003] Chinese invention patent CN100999697A discloses a preparation method and application of a spice nanocapsule dispersion. In the method, the etherified melamine resin prepolymer is used as a monomer for forming the capsule wall material, and the particle diameter of the formed capsule is 140-180...
