Description

Method for preparing green long-acting portable solid fragrance agent
Technical Field
The invention relates to the field of slow-release material application, in particular to a green long-acting portable solid fragrance agent and a preparation method thereof.
Background
The fragrance is that the essential oil is released in a certain space in a mild and controlled manner, so that people in the space can smell pleasant fragrance, and the mood and the vitality are improved. The fragrance is generally classified into a liquid fragrance and a solid fragrance. The liquid fragrance usually selects alcohol with strong dissolving power to dissolve essential oil, and porous substances such as rattans, active carbon and the like are used for helping diffusion and propagation, so that the organic solvent is volatilized to the space together; or heating or microwave fragrance spreading equipment is adopted to volatilize or atomize the essential oil into fine liquid drops to spread the fragrance through aerodynamic force, and the defect is that the fragrance is not easy to carry. The solid fragrance agent gets rid of the traditional heavy glass bottle body with heavy fragrance, can quickly and flexibly meet the fragrance requirement, does not need heating, realizes slow release diffusion by utilizing air flow, and creates a beautiful and natural indoor environment. At present, most of solid fragrances still need organic volatile curing agents to carry and diffuse the fragrances to the space by utilizing the mild sublimation of the organic volatile curing agents. Therefore, although the use is convenient and the utilization rate of the essential oil is high, unnecessary VOC pollution is brought, and chronic poisoning is more likely to be caused by mandatory long-term inhalation of organic solvents with unknown health.
Disclosure of Invention
The purpose of the invention is as follows: aiming at the problems in the prior art, the invention provides the preparation method of the green long-acting portable solid fragrance agent, which completely avoids the use of organic auxiliary reagents, does not need fragrance expanding equipment for assistance, can adjust the release rate of the fragrance, effectively ensures long-acting slow release, has simple preparation process, low cost, green use, no pollution, high utilization rate of essential oil, low residual oil rate and avoids VOC pollution.
The technical scheme is as follows: the invention provides a method for preparing a green long-acting portable solid fragrance agent, which comprises the following steps: s1: pulverizing and drying the colloid-grade attapulgite; s2: uniformly mixing the treated colloid-grade attapulgite and essential oil according to a certain proportion to prepare a high-concentration raw material, and uniformly mixing the treated colloid-grade attapulgite and the essential oil according to another proportion to prepare a low-concentration raw material; s3: quantitatively pressing the high-concentration raw materials into pills at a constant pressure; s4: and (2) taking the pills as cores, putting the low-concentration raw materials as shells, ensuring that the cores are uniformly wrapped in the shells, and then quantitatively pressing at a constant pressure for a second time to obtain the green long-acting portable solid fragrance agent with the core-shell structure.
Preferably, in S2, the mass ratio of the colloidal attapulgite to the essential oil in the high-concentration raw material is 100: 20-40.
Preferably, in S2, the mass ratio of the colloid-grade attapulgite to the essential oil in the low-concentration raw material is 100: 2-4.
Preferably, in S4, the mass ratio of the inner core to the outer shell is 1: 1.5-3.
Preferably, in S3, the standard of the constant pressure is 40-50 KN. The standard selection of quantitative constant pressure needs to be subjected to a large number of tests to obtain optimal data, because too high pressure can cause too tight and compact pressure, the fragrance volatilization is too slow to achieve the effect, too low pressure can cause too loose pressure, the fragrance volatilization is too rapid, and the service time is too short.
Preferably, in S4, the standard of constant pressure is 50-60 KN.
Preferably, in S1, the viscosity of the colloidal grade attapulgite is 1000Pa @ S or more.
Preferably, in S2, the essential oil is commercially available single or compound pure natural plant essential oil; the pure natural plant essential oil is preferably lavender essential oil or citrus essential oil.
Preferably, in S1, the colloidal grade attapulgite is pulverized to 300 mesh.
Preferably, in S1, the attapulgite is dried for 1.5 to 2.5 hours at the temperature of 190 to 210 ℃.
Has the advantages that: the attapulgite adopted by the invention is a natural one-dimensional nano material (clay mineral), and the high specific surface area and abundant pore structures lay a good material foundation for the sustained and controlled release of the essential oil. The invention completely avoids the use of organic auxiliary reagents, does not need the assistance of fragrance spreading equipment, has simple preparation process and low cost, is green and pollution-free to use, and has high utilization rate of the essential oil.
The invention adopts colloid-grade attapulgite, is a natural adhesive, has good adhesive forming characteristic, can be formed at one time by simple physical tabletting, has better mechanical strength and is convenient to carry and use.
The invention can regulate and control the hierarchical pore structure formed by the accumulation of the attapulgite nanofibers through the pressure control of physical tabletting, thereby regulating the release rate of the fragrance. The porosity is reduced along with the increase of the pressure, the release speed of the essential oil is reduced, and therefore the release rate of the essential oil can be adjusted through the regulation and control of the pressure; in addition, the invention also combines the design of taking the high-concentration raw material as the core and taking the low-concentration raw material as the core-shell structure of the coat, and can effectively ensure long-acting balanced slow release of the essential oil.
Compared with organic curing agents or other minerals such as zeolite, bentonite, kaolin and the like, the attapulgite is a clay mineral with a fibrous structure and a chain lamellar structure and has high specific surface area (300-2The specific structure and surface performance of the attapulgite clay can not only effectively control and release the essential oil, but also enable the essential oil to finally volatilize almost completely, have the lowest residual oil rate and have no VOC pollution.
