Embodiment 1

[0026] A variable color pigment, comprising the following components by weight: 30 parts of kaolin, 5 parts of white carbon black, 8 parts of color-changing fine powder, 5 parts of montmorillonite, 0.5 parts of sodium oleate, 1 part of Aminopropylamine dioleate, 30 parts of ethanol, 3 parts of ethylene glycol and 1 part of water. Wherein the discoloration micropowder is obtained by the following method: dissolving phenolphthalein and carboxymethyl cellulose in 30% ethanol aqueous solution, then adding No. 200 solvent oil, slowly adding absolute ethanol, and obtaining the discoloration micropowder after evaporating the solvent.

Embodiment 2

[0028] A color-changing pigment, comprising the following components by weight: 40 parts of calcium sulfate, 10 parts of talcum powder, 6 parts of color-changing micropowder, 10 parts of montmorillonite, 1 part of aminopropylamine dioleate, 15 parts of acetone, 3 parts of polyethylene glycol, 5 parts of ethylene glycol and 2 parts of water. Wherein the color-changing micropowder is prepared by the following method: dissolving methyl orange and carboxymethyl cellulose in 30% ethanol aqueous solution, then adding No. 200 solvent oil, slowly adding absolute ethanol, and obtaining the color-changing micropowder after evaporating the solvent.

Embodiment 3

[0030] A color-changing pigment, comprising the following components by weight: 40 parts of calcium sulfate, 10 parts of talcum powder, 6 parts of color-changing micropowder, 10 parts of montmorillonite, 1 part of aminopropylamine dioleate, 15 parts of acetone, 3 parts of polyethylene glycol, 5 parts of ethylene glycol and 2 parts of water. Wherein the color-changing micropowder is prepared by the following method: dissolving litmus and carboxymethyl cellulose in 30% ethanol aqueous solution, then adding No. 200 solvent oil, slowly adding absolute ethanol, and obtaining the color-changing micropowder after evaporating the solvent.

Abstract

The invention belongs to the technical field of fine chemicals, relates to the field of stationery and leisure products, in particular to a color-changing pigment. A color-changing pigment, comprising the following components in parts by weight: 35-50 parts of inorganic filler, 5-8 parts of color-changing fine powder, 1-10 parts of thickener, 1.5-4 parts of dispersant, 15-5 parts 30 parts of organic solvent, 1-3 parts of water and 3-8 parts of moisture regulating material. The invention proposes a color-changing powder pigment. After the oil solvent volatilizes, the polarity and acidity and alkalinity of the pigment surface change with the surrounding water content to cause color change.

Description

technical field [0001] The invention belongs to the technical field of fine chemicals, relates to the field of stationery and leisure products, in particular to a color-changing pigment. Background technique [0002] The solvents used in color products available in the market are generally single oily or water-based solvents. [0003] For example, the invention patent with the publication number CN101137729A discloses a kind of oily pigment ink composition containing at least pigment, macromolecular compound and organic solvent, containing methoxybutyl acetate accounting for 20-90% by weight of the whole ink composition as the organic solvent The above-mentioned oily ink pigment composition; especially containing nitrogen-containing and / or oxygen-containing heterocyclic compounds accounting for 1 to 50% by weight of the entire ink composition, and / or containing 1 to 50% by weight of the entire ink composition (poly ) alkylene glycol derivatives as the above-mentioned oily i...
