Abstract

Highly hydrostable abrasion resistant plastic printing ink is characterized in that: the printing ink comprises the following compositions in weight portion: 65 to 75 portions of a composition A and 5 to 10 portions of a composition B of a curing agent; the composition A comprises pigment, a bonding material and a solvent, wherein the bonding material is tribasic vinyl chloride-acetate copolymer containing hydroxyl groups and a fluoro-siloxane resin containing the hydroxyl groups; and the curing agent is hexamethylene diisocyanate biuret. An application method comprises the following steps of: separately storing the composition A and the composition B; before use, diluting the composition B with a solvent, and then adding the composition B into the composition A for even mixing and dispersing; carrying out the corona treatment on a plastic film before printing to improve the surface tension of the film, up to more than 38 dynes; and carrying out curing for 12 to 24 hours in an oven ata temperature of between 40 and 70 DEG C after printing. The invention is mainly used for making the printing ink.

Description

technical field [0001] The present invention relates to printing ink, especially to a kind of plastic printing ink with high water resistance and abrasion resistance Background technique [0002] Plastic films such as polyethylene (PE) and polypropylene (PP) are the most commonly used plastic films for flexible packaging. They are non-polar materials with a compact, smooth surface and relatively low surface energy. They are an inert surface that is not easy to infiltrate and adhere. higher technical requirements. In particular, plastic inks used in the outer packaging of refrigerated products such as liquid dairy products need to meet the requirements of water resistance and abrasion resistance. , Due to the alternation of cold and heat on the surface of the film, condensation will occur. During the entire storage, transportation and use process, it is inevitable to contact with water. If the water resistance and wear resistance are poor, it is easy to cause the ink to fad...
