Embodiment 1

[0007] Take 15 kg of Pigment Red 146 powder and grind it to 1000 mesh with a grinder; put the ground Pigment Red 146 powder into the reactor, add 12 kg of emulsified silicone oil and stir at the same time; then add 23 kg of emulsifier OP-9 and stir at the same time; Then add 14kg of ethylene glycol and stir at the same time; then add 85kg of water and stir evenly; finally use a homogenizer for homogenization, the homogenization pressure is 17MPa, and the homogenization time is 25min. Pigment Red 146 emulsion was prepared.

Embodiment 2

[0009] Take 16 kg of Pigment Red 146 powder and grind it to 1000 mesh with a grinder; put the ground Pigment Red 146 powder into the reactor, add 14 kg of emulsified silicone oil and stir at the same time; then add emulsifier OP-9 to 21 kg, and stir at the same time; Then add 11kg of ethylene glycol and stir at the same time; then add 80kg of water and stir evenly; finally use a homogenizer for homogenization, the homogenization pressure is 17MPa, and the homogenization time is 25min. Pigment Red 146 emulsion was prepared.

Embodiment 3

[0011] Take 18 kg of Pigment Red 146 powder, grind it to 1000 mesh with a grinder; put the ground Pigment Red 146 powder into the reactor, add 16 kg of emulsified silicone oil and stir at the same time; add emulsifier OP-9 to 22 kg, and stir at the same time; Then add 12kg of ethylene glycol and stir at the same time; then add 82kg of water and stir evenly; finally use a homogenizer for homogenization, the homogenization pressure is 17MPa, and the homogenization time is 25min. Pigment Red 146 emulsion was prepared.

[0012] 100g of the products of Example 1, Example 2, and Example 3 were each taken, and poured into 1000g of water, the emulsion was quickly dispersed evenly, and all had good dispersibility. The emulsions of Example 1, Example 2, and Example 3 were measured using a particle size analyzer, and the particle sizes of Example 1, Example 2, and Example 3 were 12um, 15um, and 18um, respectively. All have a very small particle size, avoiding the grainy feeling during t...

Abstract

The present invention relates to a pigment red 146 emulsion preparation method, which comprises: taking 15-18 parts of pigment red 146 powder, and grinding into 1000 mesh with a grinding machine; adding the grinded pigment red 146 powder into a reactor, and adding 12-16 parts of emulsified silicon oil while stirring; adding 21-23 parts of an emulsifier OP-9 while stirring; adding 11-14 parts of ethylene glycol while stirring; adding 80-85 parts of water, and uniformly stirring; and finally adopting a homogenizer to homogenize, wherein a homogenizing pressure is 17 MPa, and a homogenizing time is 25 min. The prepared pigment red 146 emulsion has characteristics of good dispersibility and small particle size.

Description

technical field [0001] The invention relates to a preparation method of a pigment emulsion, in particular to a preparation method of a pigment red 146 emulsion. Background technique [0002] Pigments have different properties and can be divided into oil-soluble and water-soluble pigments. In the application of pigments, oil-soluble pigments cannot be applied to water-soluble systems, and water-soluble pigments cannot be applied to oil-soluble systems. Due to the difference in the above properties, its application space is limited. If the oil-soluble pigment is applied to the water-soluble system by emulsification, or the water-soluble pigment is applied to the oil-soluble system by emulsification, the range of use of pigments with different properties will be expanded. Contents of the invention [0003] Technical problem to be solved: apply Pigment Red 146 in water-soluble system. [0004] Technical solution: The present invention discloses a preparation method of Pigme...
