preparation example 1

[0066] Preparation Example 1: Preparation of Connection Base

[0067] A1: Prepare pre-polymerized emulsion, specifically:

[0068] At room temperature, in parts by mass, a mixture of 1 part of glycidyl methacrylate and 1.5 parts of vinyl propionate was added to 10 parts of deionized water, and then 0.1 part of nonionic surfactant tetraethylene glycol monostearin was added Ester, fully stirred completely, to obtain pre-polyemulsion;

[0069] A2: Prepare the trigger solution, specifically:

[0070]In parts by mass, 0.05 part of initiator dicyclohexyl peroxydicarbonate and 0.4 part of sodium dodecylbenzenesulfonate are added to 5 parts of absolute ethanol, fully stirred to obtain a uniform initiating solution;

[0071] A3: Prepare the polymerization solution, specifically:

[0072] In terms of parts by mass, weigh 100 parts of the pre-polymerized emulsion and 3 parts of the initiating solution, and then add dropwise 2 / 3 of the total amount to 100 parts of the pre-polymerized e...

preparation example 2

[0073] Preparation Example 2: Preparation of Modified Inorganic Pigment

[0074] B1: Grind the inorganic pigment iron blue several times until its particle size≤5 μm, and then add it to the aqueous solution of polyethylene glycol 200 with a concentration of 10wt% (polyethylene glycol in the aqueous solution of iron blue and polyethylene glycol 200 The mass ratio of 200 is 1.4:1), stirring fully to obtain a suspension; adding a molar concentration of 0.8mol / L sodium bicarbonate solution (the molar ratio of methacrylic acid and sodium bicarbonate) to the aqueous solution of 10 wt% methacrylic acid content The ratio is 1:0.12), fully stirred to obtain the mixed solution;

[0075] B2: Add ammonium persulfate to the mixed solution and stir completely (the mass ratio of ammonium persulfate to methacrylic acid in the mixed solution is 0.25:100), raise the temperature to 50°C and then under nitrogen atmosphere and the temperature Add the suspension dropwise (the mass of the mixed liq...

preparation example 11-14

[0076] Preparation example 1.1-1.4: Preparation of connecting base material

[0077] In addition to replacing the heating rate in Step A3 of Preparation Example 1 from 3°C / min to 1°C / min, 5°C / min, 2°C / min and 4°C / min, the other operations were unchanged, thus repeated implementation Preparation Example 1 corresponded to Preparation Examples 1.1-1.4, and the obtained linking base materials were named DJL1, DJL2, DJL3 and DJL4 in sequence.

Abstract

The present invention relates to a kind of water-based ink, and described water-based ink comprises connection base material, modified inorganic pigment, cosolvent, antifoaming agent, stabilizer, emulsifier, wetting agent, antioxidant, penetrating agent, polyethylene wax and Deionized water also relates to the preparation method and application of the ink. The water-based ink has excellent multiple properties through unique component selection and mutual synergy, as well as unique preparation steps, so it can be applied to the field of printing technology, for example, it can be applied to advertising printing, PVC film printing, paper printing, etc. In many specific applications, it has good application prospects and promotion potential.

Description

technical field [0001] The invention relates to an ink and its preparation method and application, more specifically to a water-based ink, its preparation method and application, and belongs to the field of fine chemical industry, especially printing technology. Background technique [0002] With the advancement of science and technology and the increasing requirements of printing, higher and higher requirements are put forward for the quality, performance and environmental protection of inks. [0003] For the ink used in printing, it was mainly solvent-based ink in the early period, but the ink had very serious defects, such as the presence of heavy metals (causing serious pollution to the environment), a large amount of organic volatiles (especially aromatics such as benzene, toluene, and xylene), etc. Compounds and volatile substances such as esters and ketones) have many disadvantages, which have caused serious harm to the environment and printing operators, and have bee...
