[0008] S2. The crushed lacquer seed skin is mixed with the pretreated plant aromatherapy raw materials and granulated at low temperature;

[0009] S3. The granulated mixed raw materials are placed in a supercritical CO2 extraction device for continuous supercritical CO2 extraction, and the aromatherapy lacquer wax is obtained by separation in a separation kettle.

[0010] Furthermore, in step S2, the weight ratio of lacquer seed husk to plant aromatherapy raw material is 1:0.5-1.5.

[0011] Furthermore, in step S2, the plant aromatherapy raw material is pretreated by natural air drying or low-temperature drying, and crushed to 10-50 mesh at a temperature of 40-60°C.

[0012] Furthermore, in step S2, the granulation temperature is 45-60°C, and the diameter of the obtained granules is 0.2-0.5 cm and the length is 0.4-1.0 cm.

[0013] Furthermore, in step S2, the plant aromatherapy raw material is one of rose, osmanthus, lavender, gardenia, and cinnamon.

[0014] Furthermore, in step S3, the supercritical CO2 extraction conditions are extraction pressure 30-45MPa, extraction temperature 50-60°C; separation kettle I pressure 12-21MPa, temperature 55-65°C; separation kettles II and III pressure 6-8MPa, temperature 50-55°C.

[0015] Furthermore, in step S1, the lacquer seed husk is crushed to 5-50 mesh.

[0016] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] The preparation method of the aromatherapy lacquer wax of the present invention comprises the following steps: after the lacquer seed skin is crushed, it is fully mixed with the plant aromatherapy raw material according to a proportion, granulated at low temperature, and then the aromatherapy lacquer wax is prepared by continuous extraction using low-temperature continuous supercritical CO2. The production temperature is low, the plant fragrance is fully retained, and at the same time, the energy consumption is effectively reduced, the production efficiency is improved, the prepared aromatherapy lacquer wax has a strong fragrance, and the fragrance emission time is increased.
