[0019] First collect the fresh leaves of Pittogonia, wash the surface with water and dry naturally, and collect the Pittogonia leaf particles by airflow crushing, and mix the Pittogonia leaf particles with 5% pentamethylene at a mass ratio of 1:10. Stir and mix the dialdehyde aqueous solution and fix the leaf particles for 20 hours; after the fixation is completed, filter and collect the leaf particles, according to the mass ratio of 1:5, stir and mix the Pittosporum flower leaf particles with n-hexane and place them in an Erlenmeyer flask, at 55 °C Heated in a water bath for 1 hour, and after the water bath heating was completed, filtered and collected the filtrate, and evaporated to dryness at 45°C to prepare a waxy concentrate of Pittosporum frondosa leaves; then, according to the mass ratio of 1:3:5, Populus euphratica The pulp board, Pittosporum leaf wax concentrate and deionized water were stirred and mixed for 10 minutes, then beaten with a beater until the slurry concen...

[0025] First collect the fresh leaves of Pittogonia, wash the surface with water and dry naturally, and collect the Pittogonia leaf particles by airflow crushing, and mix the Pittogonia leaf particles with 5% pentamethylene at a mass ratio of 1:10. Stir and mix the dialdehyde aqueous solution and fix the leaf particles for 24 hours; after the fixation is completed, filter and collect the leaf particles, according to the mass ratio of 1:5, stir and mix the Pittosporum flower leaf particles with n-hexane and place them in an Erlenmeyer flask, at 60 °C Heat in a water bath for 2 hours. After the water bath heating is completed, filter and collect the filtrate, and evaporate to dryness at 50°C to prepare a waxy concentrate of Pittosporum flower leaves; then, according to the mass ratio of 1:3:5, Populus euphratica Pulp board, Pittosporum leaf wax concentrate and deionized water were stirred and mixed for 15 minutes, then beaten with a beater until the slurry concentration was conce...
