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.

Abstract

The invention relates to a preparation method of a pigment orange 71 microcapsule. The preparation method comprises the following steps that (1) pigment orange 71 powder is ground by a superfine impact mill to 450 meshes-500 meshes; (2) 90-110 parts of hexyl hydride is added into a constant-temperature stirring tank under an indoor temperature; (3) 9-14 parts of 450-mesh-500-mesh pigment orange 71 is taken to be placed in the constant-temperature stirring tank, and the temperature is set to be 40 DEG C; (4) 18-22 parts of ethyl acrylate and 15-17 parts of polyethylene glycol are slowly added into the stirring tank to be stirred, and stirring is conducted at a 100rpm rotating speed for 3-5min; (5) after stirring is completed, the temperature of the stirring temperature is set to be 65 DEG C, and after the hexyl hydride is volatilized, the pigment orange 71 microcapsule is obtained. The preparation method of the pigment orange 71 microcapsule is simple and practical, and the prepared pigment orange 71 microcapsule strengthens stability of the pigment orange 71, and widens the application space of the pigment orange 71.

Description

technical field [0001] The invention relates to a preparation method of microcapsules, in particular to a preparation method of Pigment Orange 71 microcapsules. Background technique [0002] During the storage of Pigment Orange 71, the properties of Pigment Orange 71 will gradually change as the storage time increases. In order to avoid the above situation and expand the application space of Pigment Orange 71, we can microencapsulate Pigment Orange 71. After the pigment orange 71 is microencapsulated, the outer wall material of the pigment orange 71 will protect the pigment orange 71 to prevent the properties of the pigment orange 71 from changing. At the same time, after the pigment orange 71 is microencapsulated, the pigment orange 71 The color expressiveness will be further enhanced. Contents of the invention [0003] Technical problem to be solved: Pigment Orange 71 is not stable after being placed for a long time. [0004] Technical solution: The present invention ...
