preparation example Construction

[0017] The invention also discloses a preparation method of an environment-friendly ink, comprising:

[0018] (1) Weigh 15-25 parts of ethyl acetate, 5-10 parts of hydroxyacetate, 10-15 parts of carboxylacetate and dissolve them in 50-80 parts of butanone, and stir them magnetically in a water bath at 50-60°C 10~12h, get the resin mixed solution;

[0019] (2) After the above resin mixed solution is cooled to room temperature, add 10-15 parts of dye, stir for 2-3 hours, then add 2-5 parts of conductive salt additive, 1-3 parts of lubricant, 0.5-2 parts of leveling agent, 1-3 parts of defoamer, 1.5-2.5 parts of adhesion promoter, stir evenly, adjust viscosity, and get environment-friendly ink.

[0020] The following are described with specific examples to prepare the environment-friendly ink of the present invention.

Embodiment 1

[0022] (1) Dissolve 15 parts of ethyl acetate, 5 parts of hydroxyacetate and 10 parts of carboxylacetate in 50 parts of methyl ethyl ketone, and magnetically stir for 10 to 12 hours in a water bath at 50 to 60 ° C to obtain a resin mixed solution ;

[0023] (2) After the above resin mixed solution is cooled to room temperature, add 10 parts of dye, stir for 2 to 3 hours, then add 2 parts of conductive salt additive, 1 part of lubricant, 0.5 part of leveling agent, 1 part of defoamer, 1.5 parts Adhesion promoter, stir evenly, adjust viscosity, get environment-friendly ink.

Embodiment 2

[0025] (1) Dissolve 18 parts of ethyl acetate, 6 parts of hydroxyacetate and 12 parts of carboxylacetate in 60 parts of methyl ethyl ketone, and magnetically stir for 10 to 12 hours in a water bath at 50 to 60 ° C to obtain a resin mixed solution ;

[0026] (2) After the above resin mixed solution is cooled to room temperature, add 12 parts of dye, stir for 2 to 3 hours, then add 3 parts of conductive salt additive, 1.5 parts of lubricant, 0.75 parts of leveling agent, 1.5 parts of defoamer, 1.75 parts of Adhesion promoter, stir evenly, adjust viscosity, get environment-friendly ink.

Abstract

The invention discloses environment-friendly printing ink which is prepared from the ingredients in parts by weight: 15 to 25 parts of ethyl acetate, 5 to 10 parts of hydroxyl acetate, 10 to 15 partsof carboxyacetate, 50 to 80 parts of butanone, 10 to 15 parts of dye, 2 to 5 parts of conducting salt auxiliary, 1 to 3 parts of lubricant, 0.5 to 2 parts of flatting agent, 1 to 3 parts of defoamingagent and 1.5 to 2.5 parts of adhesion promoter. The invention further discloses a preparation method of the printing ink. The method comprises the steps: (1) weighing 15 to 25 parts of the ethyl acetate, 5 to 10 parts of the hydroxyl acetate and 10 to 15 parts of the carboxyacetate, dissolving into 50 to 80 parts of the butanone and magnetically stirring for 10 to 12h under the condition of 50 to60 DEG C water bath to obtain a resin mixed solution; (2) adding 10 to 15 parts of the dye when the resin mixed solution is cooled to room temperature, stirring for 2 to 3h, then adding 2 to 5 partsof the conducting salt auxiliary, 1 to 3 parts of the lubricant, 0.5 to 2 parts of the flatting agent, 1 to 3 parts of the defoaming agent and 1.5 to 2.5 parts of the adhesion promoter, evenly stirring and adjusting a viscosity to obtain the environment-friendly printing ink. The printing ink disclosed by the invention has the advantages of short drying time, good stability, safety and environmental friendliness.

Description

technical field [0001] The invention relates to the field of ink manufacturing, in particular to an environment-friendly ink and a preparation method thereof. Background technique [0002] With the rapid development of the global economy, the continuous improvement of people's living standards, people's awareness of environmental protection and health is constantly increasing, and the safety issues of food, medicine, cosmetics and other products have attracted more and more people's attention. The labels of products such as medicines, cosmetics, etc. must be marked with instructions to protect consumers' rights and interests, such as the production date, batch number, and shelf life of the product. Therefore, general environment-friendly inkjet inks that meet the requirements of food, medicine, cosmetics, etc. have become one of the hot spots of current research. Environmentally friendly ink has broad application prospects because it does not add volatile toxic solvents, an...
