Problems solved by technology

[0017] The inks in the prior art are all inks that only have adhesion to one of PET film or PI film alone, and its main components are generally polyurethane resin, insulating carbon black, SiO 2 Matting powder and organic solvents need to purchase and select different types of inks to ensure their stability and adhesion when they need to use different substrates. This will cause trouble for the use or processing of inks, increase production costs, and greatly Reduced work efficiency

Abstract

The invention provides general insulation matte black electron gravure printing ink for PET and PI films and a preparation method thereof. The general insulation matte black electron gravure printingink comprises saturated polyester, modified polyurethane resin, hydroxyl acrylic resin, 0.1-2 parts of a dispersing agent, a leveling agent, urea formaldehyde resin modified extinction powder, white carbon black, talcum powder, ultrafine kaolin, polyethylene wax, carbon black, n-propyl acetate, ethyl acetate, saturated polyester B, an adhesion promoter and propylene glycol monomethyl ether acetate. The general insulation matte black electron gravure printing ink provided by the invention has the advantages that resin components, such as modified polyurethane resin and hydroxyl acrylic resin, with different physical and chemical properties are used, and adhesion of the gravure printing ink on base materials such as the PET and PI films is improved, so that the gravure printing ink can be respectively used on the two base materials, namely the PET film and the PI film, the work of using the printing ink on the different base materials is simplified, the cost of printing ink printing workis reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of printing inks, in particular to PET and PI film general-purpose insulating matte black electronic gravure printing inks and a preparation method. Background technique [0002] Ink (ink, printing ink) is an important material for printing. It expresses patterns and characters on the substrate by printing or inkjet painting. The ink includes main components and auxiliary components, which are evenly mixed and rolled repeatedly to form a viscous colloidal fluid. It is composed of linking material (resin), pigment, filler, auxiliary agent and solvent, etc. It is used for various printing of books, periodicals, packaging and decoration, architectural decoration and electronic circuit boards. With the increase of social demand, the variety and output of ink have also expanded and increased accordingly. [0003] Including pigments and dyes, pigments are divided into organic pigments and inorganic pigments. Th...
