preparation example Construction

[0039] like figure 1 Shown, a kind of preparation method that an embodiment of the present invention discloses prepares the aforementioned water-based ink, for example, comprises the steps:

[0040] S001: Mix and stir water-based acrylic resin, water-based polyurethane resin, film-forming aid, defoamer, dispersant, wetting agent, matting powder, water-based black slurry, thickener, and component A diluent in parts by mass Evenly, A component is obtained;

[0041] S002: Weigh the curing agent in parts by mass to obtain component B;

[0042] S003: Weigh the adhesion promoter in parts by mass to obtain component C;

[0043] S004: Mix component A, component B and component C to obtain a mixed system, and add component D according to the stated parts by mass for diluting to obtain a mixed solution;

[0044] Further, the mentioned ratio of diluting is 100: (5-15): (1-5): (0-25) for component A: component B: component C: component D.

[0045] like figure 2 As shown, one embodim...

[0050] The water-based ink of the present embodiment weighs ingredients according to the following components and parts by mass thereof:

[0051] Component A: 15 parts of water-based acrylic resin, 45 parts of water-based polyurethane resin, 8 parts of film-forming aid, 20 parts of water-based black paste, 6 parts of matting powder, 0.5 parts of defoamer, 1 part of dispersant, and 1 part of wetting agent , Thickener 0.5 parts, A component thinner 3 parts.

[0052] Component B: 15 parts of curing agent.

[0053] Component C: 2 parts of adhesion promoter.

[0054] Component D: 25 parts of mixed component diluent.

[0055] Specifically, in component A, the water-based acrylic resin is water-based hydroxyacrylic emulsion, the water-based polyurethane resin is water-based fluorine-modified polyurethane emulsion, the film-forming aid is dipropylene glycol dimethyl ether, and the water-based black pulp is high-temperature-resistant boiled water. Dispersible black paste, matting po...

[0069] The selected specific types of the water-based ink of the present embodiment and the preparation method of the water-based ink and the water-based ink coating are the same as those of the first embodiment. The difference is that the water-based ink of the present embodiment has different mass parts of its components from the first embodiment, and the water-based ink disclosed in the present embodiment is weighed according to the following components and parts by mass:

[0070] Component A: 45 parts of water-based acrylic resin, 15 parts of water-based polyurethane resin, 8 parts of film-forming aid, 20 parts of water-based black paste, 6 parts of matting powder, 0.5 parts of defoamer, 1 part of dispersant, and 1 part of wetting agent , Thickener 0.5 parts, A component thinner 3 parts.

[0071] Component B: 15 parts of curing agent.

[0072] Component C: 2 parts of adhesion promoter.

[0073] Component D: 25 parts of mixed component diluent.

Abstract

The embodiment of the invention discloses water-based ink, a preparation method thereof and a plate. The water-based ink comprises a component A, a component B, a component C and a component D, wherein the component A comprises the following components in parts by mass: 15-25 parts of water-based acrylic resin, 15-45 parts of water-based polyurethane resin, 5-10 parts of a coalescing agent, 10-20 parts of water-based black paste, 5-10 parts of matting powder, 0.5-1 part of a defoaming agent, 0.5-1 part of a dispersing agent, 0.5-1 part of a wetting agent and 0.5-2 parts of a thickening agent, and 0-5 parts of a component A diluent; the component B comprises the following components in parts by mass: 5-15 parts of a curing agent; the component C comprises the following components in parts by mass: 1-5 parts of an adhesion promoter; and the component D comprises the following components in parts by mass: 0-25 parts of a mixed component diluent. The water-based ink disclosed by the invention is convenient to coat, is firmly combined with a base material, and has the advantages of high covering power, matte smoothness, small surface tension, good recoatability, boiling resistance, high temperature resistance and strong bending resistance.

Description

technical field [0001] The invention relates to the field of chemical coatings, in particular to a water-based ink, a preparation method of the water-based ink and a board. Background technique [0002] Water-based coatings are processed by compound grinding of water-soluble resins, organic pigments, solvents and related additives. With the prosperity of the national economy, the development of the printing industry and the enhancement of people's awareness of environmental protection, the ink industry and the printing industry have also achieved rapid development, and the demand for water-based inks has grown rapidly. Compared with traditional inks, water-based coatings replace 30%-70% of toxic organic solvents in traditional inks with water, so that the inks have low VOC (volatile organic compounds, volatile organic compounds) emission values. The use of water-based coatings is conducive to promoting industrial The development of pollution prevention and control. In addi...
