Abstract

The invention provides an ink resin used for an environment-friendly solvent-type soft-packaging composite material, and a preparation method thereof. The ink resin is prepared from the following components by weight: 15 to 25% of non-crystalline type high-gloss polyester polyol, 1 to 10% of diisocyanate, 0.1 to 5% of diamine, 50 to 60% of an ester solvent and 10 to 20% of an alcoholic solvent. The invention also discloses a preparation method for the ink resin used for the environment-friendly solvent-type soft-packaging composite material. The preparation method has simple process and low requirements on equipment. The ink prepared from the ink resin used for the environment-friendly solvent-type soft-packaging composite material in the invention has the advantages of high gloss, transparency and adhesive fastness, good dispersion and stability, excellent redissolution property and blocking resistance, high compound strength, resistance to boiling in water at 100 DEG C, resistance to stewing at 121 DEG C, no benzophenone solvent, excellent printability, no odor and low residue after being printed, safety, and environment friendliness.

Description

technical field [0001] The invention belongs to the field of ink resin for printing, and relates to an ink resin for an environment-friendly solvent-type flexible packaging composite material and a preparation method thereof. technical background [0002] With the rapid development of flexible packaging composite materials, people's awareness of environmental protection of flexible packaging composite materials continues to increase, and the printing safety and environmental protection requirements for food flexible packaging composite materials are getting higher and higher. Traditional chlorinated polypropylene inks, polyamide inks, and polyurethane inks mainly use toluene, methyl ethyl ketone, cyclohexanone, etc. as solvents, among which toluene is highly toxic, while methyl ethyl ketone has a strong residual odor and has certain toxicity. When used, it is easy to pollute the air and cause great harm to human health. In order to prevent various toxic and harmful substanc...
