Problems solved by technology

Therefore, although it is easy to use and has a high utilization rate of essential oils, it also brings unnecessary VOC pollution, and it is more likely to cause chronic poisoning due to compulsory long-term inhalation of organic solvents with unknown health

Embodiment approach 1

[0021] First, crush the colloidal grade attapulgite with a viscosity of 1000Pa⋅s to 300 meshes and dry it at 200°C for 2 hours, then cool it to room temperature for later use; take the processed colloidal grade attapulgite and add pure natural citrus essential oil according to the mass ratio of 3:1. The ratio is evenly mixed to make high-concentration raw materials, and put into sealed reagent bottle A for use. Take 2.5g of high-concentration raw material from the sealed reagent bottle A and use a tablet press with a pressure of 45KN to press it into a pill as the core; then take the processed colloid-grade attapulgite and add pure natural citrus essential oil according to the mass ratio of 30:1. Mix evenly to make low-concentration raw materials, and put them into sealed reagent bottle B for later use. From the sealed reagent bottle B, take low-concentration raw materials twice the weight of the core as the shell, and the shell will evenly wrap the pills, and perform secondar...

Embodiment approach 2

[0023] This embodiment is roughly the same as Embodiment 1, and the only difference is that the pressure of the tablet press is different. The high-concentration raw material with a quality of 2.5 g is compressed into a pill by a tablet press with a pressure of 50KN as the core; The tablet press pressure during secondary compression is 60KN.

[0024] The prepared green long-lasting portable solid fragrance with core-shell structure can volatilize fragrance for 3.3 months at room temperature, and the residual oil rate of essential oil is as low as 1.1%.

Embodiment approach 3

[0026] This embodiment is roughly the same as Embodiment 1, and the only difference is that the pressure of the tablet press is different. The high-concentration raw material with a quality of 2.5 g is compressed into a pill by a tablet press with a pressure of 40KNKg as the core; the pill wrapped in the shell The tablet press pressure when carrying out secondary compression is 50KNKg.

[0027] The prepared green long-lasting portable solid fragrance with core-shell structure can volatilize its fragrance for nearly 3 months at room temperature, and the residual oil rate of essential oil is as low as 1.3%.

Abstract

The invention relates to the field of slow-release material application, and discloses a preparation method of a green long-acting portable solid fragrance agent. The method comprises the following steps: S1, crushing and drying 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 according to another proportion to prepare a low-concentration raw material; S3, pressing the high-concentration raw material into pills at constant pressure; and S4, taking the pills serve as inner cores, placing the low-concentration raw material into the pills to serve as outer shells, ensuring that the inner cores are evenly wrapped in the outer shells, then performing secondary pressing under the constant pressure, and preparing the green long-acting portable solid fragrance agent of the core-shell structure. According to the method, the use of organic auxiliary reagents is completely eradicated, fragrance diffusion equipment assistance is not needed, the fragrance release rate can be adjusted, the long-acting slow release is effectively ensured, the preparation process is simple, the cost is low, the use is green and pollution-free, the essential oil utilization degree is high, the residual oil rate is low, and the VOC pollution is avoided.

Description

technical field [0001] The invention relates to the application field of slow-release materials, in particular to a green long-lasting portable solid fragrance and a preparation method thereof. Background technique [0002] Fragrance is to release essential oils in a certain space at a moderate and controlled speed, so that people in it can smell a pleasant fragrance, thereby helping to improve mood and vitality. Fragrances are usually divided into liquid fragrances and solid fragrances. Liquid fragrances usually choose alcohol with strong solubility to dissolve essential oils, and use porous materials such as rattan and activated carbon to help spread them. The disadvantage is that organic solvents will also volatilize into the space; or use heating or microwaves to volatilize essential oils. Or atomized into fine droplets to spread the fragrance through air power, the disadvantage is that it is not easy to carry. Solid fragrances get rid of the heavy glass bottles of tra...
