Plastic ink for solvent-free adhesive compounding and preparation method thereof

Abstract

The invention provides ink special for polyurethane-type solvent-free adhesive compounding. The ink is prepared from ink main body connecting materials, titanium dioxide, packing, polyethylene wax, an alcohol ester solvent and a silane coupling agent; the ink main body connecting materials are composed of alcohol-ester-soluble polyurethane resin liquid and ternary vinyl chloride-vinyl acetate resin, and the ink further contains a certain amount of polyepoxide resin liquid. In addition, the invention provides a method for preparing the ink. According to the ink, the adverse effect generated by the ink and an solvent-free adhesive during solvent-free adhesive compounding of a printed product can be relieved and avoided, and the problems that a compounded product is dark, and white dots are generated on the compounded product can be solved; meanwhile, volatilization of the organic solvent can be avoided, and therefore the environmental protection requirement is met while the using cost is reduced; in addition, the ink does not generate color changes at the high temperature.

Description

technical field [0001] The invention belongs to the field of printing inks, and relates to a plastic ink suitable for solvent-free adhesive compounding and a preparation method thereof, and more particularly relates to a solvent-free ink that uses alcohol ester polyurethane resin and ternary vinyl chloride resin as ink main binders. Glue compounded plastic ink and preparation method thereof. Background technique [0002] At present, the lamination of food flexible packaging enterprises in the domestic market is still mainly dry lamination. However, with the rapid economic development and the gradual maturity of various conditions, the domestic solvent-free composite and solvent-free polyurethane adhesives are facing unprecedented opportunities. In particular, the new national standard GB / T10004-2008 "Plastic composite film for packaging, bag dry composite, extrusion composite" was introduced and implemented on August 1, 2009 (total solvent residue ≤ 5mg / m 2 , Benzene solve...
