Description
Technical Field
The invention relates to the technical field of insulating gravure printing black ink, in particular to insulating gravure printing black ink for butanone wiping resistance on a film material.
Background
The PET/PI material in the market is mainly used for industrial adhesive tapes (KAPTON adhesive tapes), microelectronic products and the like, the industrial adhesive tapes are insulating voltage-resistant electronic adhesive tapes and are used for bonding and temporarily fixing various electronic parts in digital products, and also used for battery packaging, electromechanical insulation packaging and pasting of a manufacture nameplate or panel and the parts, and the PI material is widely used as a dielectric space layer, a protective covering layer and a base material of a metal film in the microelectronic industry due to excellent high temperature resistance, mechanical property, radiation resistance, low dielectric constant, high resistivity and the like, and is particularly used in the fields of battery packaging protective layers and flexible copper clad plates.
The prior gravure printing black covering ink used on PET/PI materials is generally prepared from one or more solvent type saturated polyester resins and one or more solvent type polyurethanes, and is matched with a dispersant, a carbon black filler, a delustering filler, a solvent and an auxiliary agent in a proper proportion, so that the performance requirements of adhesion, blackness, covering, gloss, insulativity and the like are met.
The existing system ink has low or no corrosion resistance of more than 90 percent to solvents (such as ethyl acetate, butanone and the like), and can have certain resistance to alcohol (500 gf/30-40 times) at most; in the market, a few of printing inks can meet the requirement of a printing ink coating on corrosion resistance to a solvent, such as an epoxy system, but the direct adhesion of the printing ink of the epoxy system on a PI material is poor, and the direct use of the printing ink of the epoxy system has great potential safety hazard for terminal application; therefore, in the prior art, a layer of 'bridging' is generally selected to be coated between the epoxy system ink and the PI material to ensure the adhesion, but a coating process is added, so that the production cost is increased.
Therefore, the solvent type saturated polyester resin, solvent type polyurethane and epoxy resin system ink in the prior art has the following defects:
firstly, the saturated polyester or polyurethane resin is limited by the molecular structure of the resin, and the formed coating film is basically solvent-intolerant, and can be easily dissolved by common ester and ketone solvents;
secondly, isocyanate curing agent is used to react with hydroxyl in saturated polyester or polyurethane resin, Tg point and crosslinking density after film forming are improved, resistance to ester or ketone solvent is low, and solvent-resistant coating cannot be formed;
thirdly, after the epoxy system resin is formed into a film, the effect of resisting solvents such as butanone and ethyl ester is good, but the adhesion to a PET/PI material is poor, and after a certain amount of matting powder is added, the fluidity of ink is poor, the contact is large, and the gravure printing effect is poor;
fourthly, the compatibility of the epoxy system resin and other polyester system resins is poor, although part of models have certain compatibility, the film appearance is poor, and better splicing combination is difficult to achieve;
fifthly, an amine curing agent needs to be added into a common epoxy resin system, the reaction temperature is higher, generally higher than 150 ℃, and the use of the system on a PET material is limited due to the higher drying temperature;
sixth, some hydroxyl-modified epoxy resins can be cured by reaction with an isocyanate curing agent at relatively low temperatures (about 130 ℃) or at room temperature, but excellent adhesion to PET/PI materials is difficult to achieve.

The polycarbonate diol used is a mixed solution of Asahi chemical compounds T5652 and G4672, and has a comprehensive average molecular weight of 2000, so that the polycarbonate diol has very excellent alcohol resistance, flexibility and scratch resistance after completely reacting with an isocyanate curing agent; the used hydroxy acrylic resin is a mixed solution of long-chain hydroxy acrylic resin and branched-chain hydroxy acrylic resin, the comprehensive solid content of the hydroxy acrylic resin is 40 percent, the glass transition temperature reaches 70 ℃, and the molecular weight range is as follows: 4500, the hydroxyl value range is 40mgKOH/g, so as to accelerate the curing speed of the ink system, and the hydroxyl acrylic resin used in the invention has good compatibility with the polycarbonate diol used in the invention, and further has the performance characteristics of stable storage, film appearance effect, excellent solvent resistance and the like; the used dispersing agent is a mixed solution of British excellent card 605S and BYK-163, can effectively disperse carbon black and blue pigment filler, improves the blackness of a coating, reduces the viscosity of the ink to prevent pseudo-thickening, and has a certain effect of improving the insulation effect of the whole ink system; the used carbon black is a mixed liquid of Degussa 4A and Mitsubishi MA-11, the used carbon black is easy to disperse, convenient to construct and stronger in tinting strength, and provides good blackness and coverage for an ink system, the selected carbon black is high-blackness insulating carbon black, the good insulativity can be ensured under the condition of a large addition amount (38 percent of the relative resin solid content), and the carbon black is matched with special blue color filler and extinction filler according to a certain proportion to achieve a matte black effect with a blue phase and high blackness, so that the obtained ink has higher blackness and smaller color difference fluctuation; the blue pigment filler is a mixed solution of phthalocyanine blue and milorin, so that the blue phase requirement of the ink after film formation can be effectively improved, the color difference b value is reduced, the color difference L value and the color difference a value of a film are not influenced, the viscosity of the ink is not influenced, and the ink is not pseudo-thick due to the higher addition amount; the main solvent is a mixed solution of isophorone and butanone, so that the viscosity and drying speed of the ink can be effectively adjusted, the ink can be quickly dried in the coating process by matching according to a certain proportion, the surface of the coating is smooth, the carbon black and the pigment can be better and uniformly distributed in the ink by matching 25 parts of the solvent, and the storage time of the ink is prolonged; the used cosolvent is a mixed solution of diacetone alcohol and ethylene glycol monobutyl ether, the compatibility of polycarbonate diol and hydroxy acrylic resin can be effectively improved, and the cosolvent has the best cosolvent effect when the using amount is 7 parts; the used auxiliary agent is a mixed liquid of an organic tin drier and an organic amine drier, the reaction of hydroxyl in the resin connecting material and NCO groups in an isocyanate curing agent can be accelerated, so that the drying rate of an ink image layer is increased, and the reaction speed can be effectively increased without influencing the use activation period of the ink due to low addition amount.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
