Problems solved by technology

[0002] Hair colorants are composed of resins, pigments, additives and solvents. The performance of the paint and the solvent used to dilute it during use are mainly determined by the resins; currently, the resins used in hair colorants are mostly polyurethane resins and acrylate resins. And alkyd resin, etc., most of them use benzene as solvent, which is not only expensive, but also causes great environmental pollution during production and use.

Embodiment 1

[0050] The preparation of embodiment 1 alcohol-soluble resin used in the present invention

[0051] Equipment: The equipment required by the present invention is: reactor, which is equipped with agitator, reflux condenser, stainless steel dropping tank, heating and temperature controller.

[0052] ①. Add 30 kg of vinyl acetate, 4 kg of methyl acrylate, and 10 kg of isopropanol as a diluent into the reaction kettle together, heat up and stir.

[0053] ②. 30 kg of vinyl acetate, 4 kg of methyl acrylate, 20 kg of methyl methacrylate, 5 kg of methacrylic acid, 2 kg of hydroxypropyl acrylate, 5 kg of glycidyl methacrylate, azobisisobutyronitrile 0.6 kg is added to the drop-adding tank as component B. When the temperature of the material in the kettle rose to the reflux temperature, it was dropped into the kettle within 2 hours, and then reacted for 1 hour.

[0054] ③. After dissolving 0.2 kg of azobisisobutyronitrile in 5 kg of ethyl acetate, drop it into the kettle within 0.5 ho...

Embodiment 2

[0056] Embodiment 2 Preparation of alcohol-soluble hair colorant of the present invention

[0057] The formula of producing alcohol-soluble hair colorant with resin of the present invention is as follows (weight ratio):

[0058] Resin solution (solid content 50%) 40 prepared by embodiment 1

[0059] Dye 10 parts

[0060] 15 parts distilled water

[0061] 15 parts absolute ethanol

[0062] Spice 0.05 parts

[0063] The technique of producing alcohol-soluble hair colorant with resin of the present invention is as follows:

[0064] Put the above raw materials into the container, stir at high speed for 10 minutes, let them fully mix and disperse evenly.

[0065] Because the present invention uses the alcohol-soluble resin synthesized with vinyl acetate as the main raw material, the goals of cost reduction and environmental protection are realized on the premise of ensuring product performance.

Abstract

An alcohol-soluble hair coloring agent features that the resin used by it is an alcohol-soluble resin prepared from vinyl acetate as primary raw material, resulting in low cost and environmental protection.

Description

technical field [0001] The present invention relates to a hair coloring agent, in particular to a hair coloring agent using alcohol as a solvent. technical background [0002] Hair colorants are composed of resins, pigments, additives and solvents. The performance of the paint and the solvent used to dilute it during use are mainly determined by the resins; currently, the resins used in hair colorants are mostly polyurethane resins and acrylate resins. And alkyd resin, etc., they mostly use benzene as solvent, not only the price is more expensive, but also cause great environmental pollution during production and use. [0003] The hair colorant prepared by the present invention uses a new type of alcohol-soluble resin, which is polymerized from the cheapest monomer raw material on the market—vinyl acetate as the main raw material plus other monomers, thereby meeting the requirements of both environmental protection and environmental protection. It is cheap and non-toxic and...
