Abstract

The invention discloses water-based scratch-resistant ink for plastic films. The ink is prepared from the following five raw materials in percentage by mass: raw materials A comprise water-based matting polyurethane PU 980, water-based matting polyurethane PU 940 and water-based glossy polyurethane PU 77; raw materials B comprise a water-based defoaming agent TEGO 1488 and a water-based defoamingagent DF7072; raw materials C comprise a water-based film forming additive and purified water A; raw materials D comprise a water-based thickening agent RHEOLATE 288, water-based wax slurry W-2335A, awater-based leveling agent DAPRO-77, a water-based wetting agent Surfynol 420, a water-based PH adjusting solution DMA and a water-based crosslinking agent XL-725; a raw material E comprises purifiedwater B. The production process of the ink comprises the following steps: sequentially adding the raw materials A to a stirring barrel, and adding the raw materials B slowly and sequentially under stirring; premixing the raw materials C, and adding the premixed raw materials C slowly under stirring; adding the raw materials D sequentially under stirring; finally, adjusting viscosity by a QC worker. The ink replaces a UV scratch-resistant coating and a common solvent scratch-resistant coating, and the problems of large odor of existing UV scratch-resistant coatings, poor scratch resistance ofsolvent coatings and potential safety hazards in the production and use processes are solved.

Description

technical field [0001] The invention relates to a water-based gravure coating ink, in particular to a water-based anti-scratch ink used for plastic films and a production process thereof. Background technique [0002] In the field of high-end packaging boxes, in order to protect the appearance of the packaging box from damage, moisture and improve the visual effect of the surface, a layer of plastic film is compounded. The surface of the plastic film is too soft. During the use of the packaging box, hard objects such as fingernails, packaging materials, etc. will often rub or collide with each other, resulting in scratches and marks on the surface, which will seriously affect the appearance of the product packaging. In order to To solve this problem, we will pre-gravure coat a layer of scratch-resistant ink in the composite plastic film to solve it. The initial method is to apply UV-type anti-scratch coating on the plastic surface first, but after the UV anti-scratch coatin...
