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 particle diameters of 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 12 μm, 15 μm, and 18 μm, respectively. All have a very small particle size, avoidin...

Abstract

The invention relates to a preparation method of Pigment Red 146 emulsion. The preparation process steps are as follows: take 15-18 parts of Pigment Red 146 powder, grind it to 1000 mesh with a grinder; put the ground Pigment Red 146 powder into a reactor, Add 12 to 16 parts of emulsified silicone oil and stir at the same time; add 21 to 23 parts of emulsifier OP-9 and stir at the same time; add 11 to 14 parts of ethylene glycol and stir at the same time; add 80 to 85 parts of water, Stir evenly; finally use a homogenizer for homogenization, the homogenization pressure is 17MPa, and the homogenization time is 25min. The prepared pigment red 146 emulsion has good dispersion 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...
