Embodiment Construction

[0026] Polyurethane resin composite printing ink and manufacture method thereof are characterized in that polyurethane resin, vinyl chloride resin, solvent, pigment, dispersing aid are raw materials, and described solvent comprises toluene, methyl ethyl ketone, isopropanol, and specific formula ratio is:

[0027] Polyurethane resin liquid (30% solid content): 25%-40%

[0028] Vinyl resin: 0-4%

[0029] Pigment: 5%-25%

[0030] Dispersing aid: 0.2%-0.5%

[0031] Toluene: 0-20%

[0032] Butanone: 25%-35%

[0033] Isopropanol: 5%-15%

[0034] Polyurethane resin is formed by the stepwise addition polymerization reaction of diisocyanate and high molecular weight diol, and then extended by low molecular weight active hydrogen compounds such as polyamine or polyol with a molecular weight of less than 500.

[0035] Among them, the polymer diol can be all known polymer diols in the polyurethane industry, commonly used polyester diol, polyester amide diol, polyether diol, polyether...

Abstract

The invention discloses a polyurethane resin compound ink and preparation method thereof, comprising polyurethane resin, chloride-vinyl acetate resin, solvent, dye and dispersing auxiliary, wherein the solvent comprises methyl benzene, butanone, isopropyl alcohol. The composition of the polyurethane resin compound ink is: polyurethane resin liquor (30% solid content) 25-40%, chloride-vinyl acetate resin 0-4%, dye 5-25%, dispersing auxiliary 0.2-0.5%, methyl benzene 0-20%, butanone 25-35%, isopropyl alcohol 5-15%. The invention provides polyurethane resin compound ink with wide application range, good thermal stability, good adhesion and no aromatics solvent, in order to conquer the lacks such as not environment protection, narrow application range and bad thermal stability.

Description

【Technical field】 [0001] The invention relates to polyurethane composite ink, and the invention also relates to a manufacturing method of polyurethane composite ink. 【Background technique】 [0002] China's ink manufacturing industry has developed rapidly in the past 20 years since it began to produce benzene-soluble composite inks with chlorinated polypropylene resin as the main binder in the early 1980s, and the manufacturing and printing processes of inks are all It is very mature, but from the analysis of the development trend of gravure composite ink, there are the following insurmountable shortcomings in the production and use of benzene-soluble composite ink: (1) A large amount of aromatic hydrocarbon solvents are used: because the main binder polyurethane resin of the ink is in the Toluene is used in the synthesis process, and it also needs to be dissolved with toluene; so the main resin of the existing benzene-soluble composite ink is toluene as a true solvent, and i...
