Problems solved by technology

[0003] Solvent-free lamination is widely adopted by many enterprises because of its fast lamination machine, no solvent residue, and low cost. However, due to the low molecular weight of solvent-free adhesives, it is easy to permeate during the bonding process with the ink film layer, which may easily cause composite products to break out. Darkness, white spots, etc.
Due to the fast compounding speed of the solvent-free adhesive compounding machine, it is easy to cause a large number of compound products to be scrapped, resulting in economic losses

Abstract

The invention provides white ink which overcomes permeability, guarantees product quality and is suitable for solvent-free glue compositing and a preparation method thereof. To meet the requirements of solvent-free glue compositing, a formula system is modified, a silane coupling agent is added into a formula, the affinity of modified polyurethane resin and modified ternary Vinisol OH is improved, the leveling performance of ink is improved, and an ink film formed in the ink printing drying processing is high in surface tension and compactness. Accordingly, after the white ink is composited with solvent-free glue, the permeability of solvent-free glue molecules is avoided, white points of a composited product is avoided, and the quality of the printing packaging product is improved.

Description

technical field [0001] The invention relates to a printing ink and a preparation method thereof, in particular to a white ink suitable for compounding with solvent-free glue, and a preparation method of the white ink. Background technique [0002] At present, the composite method used in food flexible packaging in the domestic market is mainly dry composite. With the rapid development of the economy and the gradual maturity of various conditions, the domestic solvent-free composite and solvent-free polyurethane adhesives are facing unprecedented opportunities, especially in the new national standard GB / T10004-2008 "Plastic composite films and bags for packaging Dry compounding, extrusion compounding" was introduced and implemented on August 1, 2009. The standard stipulates that "the total amount of solvent residues is ≤ 5mg / m2, and benzene solvents must not be detected." Therefore, more and more flexible packaging Enterprises began to pay attention to solvent-free laminatio...
