Abstract

The invention belongs to the field of water-based ink and production technology thereof, and in particular relates to high-performance water-based epoxy ink and a preparation method thereof. The water-based ink is prepared from a water-based epoxy resin emulsion binder, pigments, auxiliaries, water and other little alcohol substance. The preparation method comprises the following steps of: takingwater-based epoxy resin as the binder; adding a certain amount of pigments, solvent, defoaming agents, wetting agents, dispersing agents and the like; mixing and grinding the materials to prepare a component A; fully mixing a certain amount of water-based epoxy hardener and a proper amount of water to prepare a component B; and fully and uniformly mixing the component A and the component B, and filtering the mixture through a screen to prepare the ink. The prepared ink has the advantages of good solvent resistance, water resistance, gloss retention and adhesive force, stable performance, quick drying, good printing adaptability, dark ink color and bright colors. Because the solvent is water, the ink has the characteristics of no toxicity, no pungent odor, noninflammability, no pollution and the like and is favorable for protecting environment and improving construction environmental quality.

Description

technical field [0001] The invention belongs to the field of water-based ink and a production process thereof, in particular to a high-performance water-based epoxy ink and a preparation method thereof. Background technique [0002] Ink is a homogeneous mixture made of pigments, binders, fillers and additional materials after preparation, stirring and grinding. It is a kind of color, certain fluidity, suitable thin and thick, mainly used in the printing industry, and can be dried on the substrate. [0003] Oil-based inks use organic solvents (toluene, xylene, industrial alcohol, etc.) as solvents. Since the solvent-based inks are volatilized during the drying process, the construction environment will deteriorate, and it will also cause environmental pollution. After printing Toxic substances remaining on the surface of the product cause product contamination, and solvent-based ink is flammable and explosive, posing potential safety hazards in production and transportation....
