Embodiment 1
[0007] (1) Grind the powder of Pigment Orange 71 to 500 mesh with an ultra-micro impact mill; (2) Add 110kg of n-hexane into the constant temperature stirring tank at room temperature; (3) Take 500 mesh of Pigment Orange 71 to 14kg, put it into the constant temperature stirring In the tank, the temperature is set at 40°C; (4) Slowly add 18kg of ethyl acrylate and 15kg of polyethylene glycol into the stirring tank, and stir after adding, the stirring speed is 100rpm, and the time is 5min; (5) Stir Finally, the temperature of the stirring tank was set to 65° C., and the pigment orange 71 microcapsules were obtained after n-hexane evaporated to dryness.
Embodiment 2
[0009] (1) Grind Pigment Orange 71 powder to 450 mesh using an ultra-micro impact mill; (2) Add 100kg of n-hexane into a constant temperature stirring tank at room temperature; (3) Take 450 mesh Pigment Orange 71 to 12kg, put it into constant temperature stirring In the tank, the temperature is set at 40°C; (4) Slowly add 20kg of ethyl acrylate and 17kg of polyethylene glycol into the stirring tank, and stir after adding, the stirring speed is 100rpm, and the time is 3min; (5) Stir Finally, the temperature of the stirring tank was set to 65° C., and the pigment orange 71 microcapsules were obtained after n-hexane evaporated to dryness.
Embodiment 3
[0011] (1) Grind Pigment Orange 71 powder to 500 mesh using an ultra-micro impact mill; (2) Add 90kg of n-hexane to a constant temperature stirring tank at room temperature; (3) Take 500 mesh Pigment Orange 71 to 9kg, put it into constant temperature stirring In the tank, the temperature is set at 40°C; (4) Slowly add 22kg of ethyl acrylate and 16kg of polyethylene glycol into the stirring tank, and stir after adding, the stirring speed is 100rpm, and the time is 4min; (5) Stir Finally, the temperature of the stirring tank was set to 65° C., and the pigment orange 71 microcapsules were obtained after n-hexane evaporated to dryness.
[0012] The Pigment Orange 71 microcapsules prepared in Example 1, Example 2, and Example 3 did not change after being placed for 2 years, and had good stability.
