Problems solved by technology

[0008] 3. Epoxy system resin has good resistance to butanone, ethyl ester and other solvents after film formation, but has poor adhesion to PET / PI materials, and after adding a certain amount of matting powder, ink fluidity is poor, thixotropy is large, gravure printing poor effect;
[0009] 4. Epoxy system resin has poor compatibility with other polyester system resins. Although some models have certain compatibility, the appearance of the coating film is poor, and it is difficult to achieve a good combination;
[0010] 5. Ordinary epoxy resin systems need to add amine curing agents, and the reaction temperature is relatively high, generally above 150°C. The high drying temperature limits the use of this system on PET materials;
[0011] 6. Some hydroxyl-modified epoxy resins can react and cure with isocyanate curing agents at lower temperatures (about 130°C) or at room temperature, but it is also difficult to achieve excellent adhesion on PET / PI materials

Abstract

The invention discloses butanone-wiping-resistant insulating intaglio printing black ink for thin-film materials and belongs to the technical field of insulating intaglio printing black ink. The butanone-wiping-resistant insulating intaglio printing black ink for thin-film materials comprises ingredients: a resin binder, a solvent, a dispersant, a carbon black filler, a blue pigment / filler, an extinction filler, a curing agent and an assistant. According to the butanone-wiping-resistant insulating intaglio printing black ink, the selected resin binder achieves a good compatible effect under the condition that a prime solvent and a cosolvent are matched according to a certain proportion, and a prepared ink coating is good in apparent effect; the ink disclosed by the invention not only can simultaneously achieve the characteristics of matte black blue phase, good coverage, high insulatibity, solvent resistance, storage stability, constructability, and the like, but also can achieve theseproperties without stacking a variety of coatings; and meanwhile, the ink can achieve very excellent adhesive power on PI materials.

Description

technical field [0001] The invention relates to the technical field of insulating gravure printing black ink, in particular to an insulating gravure printing black ink used for butanone-resistant wiping on film materials. Background technique [0002] PET / PI materials on the market are mainly used in industrial tape (KAPTON tape), microelectronic products, etc. Industrial tape is an electronic tape with insulation and voltage resistance, which is used for bonding and temporary fixing of various electronic components in digital products. Used for battery packaging, electromechanical insulation packaging, making nameplates or pasting panels and components, PI materials are widely used for their excellent high temperature resistance, mechanical properties, radiation resistance, low dielectric constant and high resistivity. It is used in the microelectronics industry as a dielectric space layer, a protective covering layer and substrate for metal films, especially in the field o...
