Embodiment 1

[0038] Example 1: First synthesize maleic acid modified chlorinated polypropylene emulsion. In a four-necked flask, add 20 parts of solvent gasoline, 15 parts of ethyl acetate, 15 parts of chlorinated polypropylene solids, and heat to dissolve under the protection of nitrogen to obtain a solution with a solid content of 30%. Add 2.5 parts of maleic acid to the solution (Acid anhydride), 1 part of benzoyl peroxide, the reaction is terminated after being incubated at 80°C for 3 hours to obtain a maleic acid-modified chlorinated polypropylene resin solution.

[0039] Continue to cool the resin solution to 60°C, add organic amine AMP95 (2-amino-2-methyl-1-propanol) dropwise until the neutralization is complete, vacuum to remove the organic solvent, and add 40 parts of deionized water while it is hot The mixed liquid with emulsifier is dispersed in the emulsifier at high speed, inverted and emulsified to obtain a modified emulsion. The solid content of the emulsion is 30%.

Embodiment 2

[0041] Example 2: First synthesis of acrylic acid modified chlorinated polypropylene emulsion. In a four-necked flask, add 20 parts of cyclohexane, 15 parts of ethyl acetate, and 15 parts of chlorinated polypropylene solids, and heat to dissolve under the protection of nitrogen to obtain a solution with a solid content of 30%. Add 4 parts of acrylic acid to the solution. One part of benzoyl peroxide was kept at 80° C. for 3 hours and then the reaction was terminated to obtain an acrylic acid-modified chlorinated polypropylene resin solution.

[0042] Continue to add organic amine AMP95 (2-amino-2-methyl-1-propanol) dropwise to the resin solution until the neutralization is completed, vacuum to remove the organic solvent, and add 40 parts of deionized water and emulsifier while it is hot. Liquid, disperse in an emulsifier at high speed and reverse emulsify to obtain a modified emulsion. The solid content of the emulsion is 30%.

Abstract

The invention relates to water-based ink for the package printing of a high-adhesion film and a manufacturing method thereof. The water-based ink is prepared from the following raw materials in percentage by weight: 10 to 30 percent of water, 5 to 25 percent of alcoholic solvents, 5 to 50 percent of modified chlorinated polypropylene emulsion, 0 to 40 percent of auxiliary blended emulsion, 5 to 40 percent of pigment, and 1 to 15 percent of assistant. The modified chlorinated polypropylene emulsion is formed by using functional organic acid to initiate graft copolymerization through free radicals in non-aromatic solution, using organic amine for neutralization, then removing a solvent and performing a phase inversion emulsification process, wherein the using weight of the functional organic acid in the formula is between 1 and 10 percent. The water-based ink and the manufacturing method thereof have the advantages of synthesizing and using a functional organic acid modified chlorinated polypropylene aqueous emulsion and matched oil manufacturing technology with disperse pigment and compound formula based on the functional organic acid modified chlorinated polypropylene aqueous emulsion. The water-based ink can greatly improve the adhesion and compound properties of ink on films.

Description

Technical field [0001] The invention relates to a water-based ink and a manufacturing method thereof, and mainly relates to a water-based ink for high-adhesion film packaging printing and a manufacturing method thereof. Background technique [0002] In order to meet the important directions of solving fire safety, reducing petroleum resource consumption, reducing atmospheric pollution and improving food packaging hygiene requirements, for the ink and plastic film printing industry, a recognized consensus is to develop and use water-based inks. In this field, many researchers have carried out pioneering work. This article has also noticed some published ink invention patents for plastic film printing, such as: Publication No. CN101003703A "Manufacture of water-based flexo and intaglio plates Composite white ink", CN101029174A "Water-based gravure printing ink for plastic film", CN101054490A "Water-based multi-purpose plastic composite and surface printing ink and its preparation m...
