Description

Technical Field

[0001] The invention belongs to the technical field of inks, and in particular relates to a solvent-resistant wiping UV ink and a preparation method thereof. Background Art

[0002] UV ink is widely used in UV lithography, screen printing and other fields due to its fast drying, environmentally friendly and pollution-free, and high resolution. Its excellent physical properties and chemical stability make it a leader in light-curing printing materials.

[0003] However, UV ink uses polymer materials with photocuring properties as binders, and has the defect of insufficient solvent wiping resistance, which reduces the durability of UV ink and greatly limits the application range of UV ink. The current UV ink has added some functional groups with special chemical structures in its formula design to enhance its resistance to solvents. Among them, silicone additives are the most widely used. They have low affinity for most solvents and are difficult to interact with polymer chains and cause swelling. The surface energy of silicone materials is low, making it difficult for solvents to wet their surfaces. In addition, silicon-oxygen bonds have high chemical stability and are not easy to react chemically with most solvents. They can form a shielding layer in the ink layer, which can improve the solvent resistance of the ink to a certain extent. However, the performance improvement is limited, and silicone reduces the cohesion of the ink layer. The introduction of a large amount of silicone additives will lead to a decrease in the adhesion performance of the ink layer. Summary of the invention

[0004] In order to solve the technical problems mentioned in the background technology, the object of the present invention is to provide a solvent-resistant wiping UV ink and a preparation method thereof.

[0005] The purpose of the present invention can be achieved through the following technical solutions: A solvent-resistant wipeable UV ink is composed of the following components: 15-20wt% of a pigment, 1.9-2.4wt% of a photoinitiator, 5.5-7.2wt% of an organosilicon additive, 1.5-2wt% of a wetting and dispersing agent, 1.2-1.6wt% of a leveling agent, 1-1.3wt% of a defoaming agent, 1.4-1.8wt% of a covering agent and 16-22wt% of a cosolvent, with the remainder being an acrylate linker.

[0006] The organosilicon additive is prepared by the following method: Step A1: Triallylamine, γ-chloropropyltrimethoxysilane, iodine and anhydrous toluene are mixed, dry nitrogen is introduced for protection, the temperature is raised to 80-90°C, stirring is applied at 60-90 rpm, the reaction is carried out for 25-30 hours, and after the reaction is completed, toluene is removed by vacuum rotary evaporation to obtain a quaternary ammonium matrix; Furthermore, the feed ratio of triallylamine, γ-chloropropyltrimethoxysilane, iodine and anhydrous toluene is 10mmol:10mmol:8-12mg:25-35mL, and under the promotion of elemental iodine, γ-chloropropyltrimethoxysilane and triallylamine undergo quaternization reaction.

[0007] Step A2: Mix the quaternized matrix, the terminal mercapto silicone oil, azobisisobutyronitrile and tetrahydrofuran, heat to 45-55°C, stir at 120-180 rpm, pre-react for 2-3 hours, and then apply 150-200 W / m 2 UV irradiation, continue the reaction for 1.2-1.6 hours, and after the reaction is completed, remove tetrahydrofuran by rotary evaporation to obtain a silicon-loaded intermediate; Furthermore, the feed ratio of the quaternized matrix, the mercapto content of the terminal mercapto silicone oil, azobisisobutyronitrile and tetrahydrofuran is 10mmol:62-65mmol:40-60mg:100-150mL. Under the activation of azobisisobutyronitrile and the promotion of ultraviolet light, the double bond of the terminal mercapto silicone oil and the quaternized matrix is ​​added to introduce branched organic silicon chains and terminal mercapto groups.

[0008] Step A3: Mix the silicon-loaded intermediate, anhydrous sodium sulfate and acetone, introduce dry nitrogen protection, apply stirring at 90-120 rpm at room temperature, slowly add methacryloyl chloride to react for 1.6-2.2 hours, then heat and reflux for 20-30 minutes, and after the reaction, remove acetone by rotary evaporation to obtain an organosilicon additive; Furthermore, the feed ratio of the silicon-supported intermediate, methacryloyl chloride, anhydrous sodium sulfate and acetone is 10 g: 18-26 mmol: 0.1-0.15 g: 30-45 mL. Under low temperature conditions, the highly active methacryloyl chloride esterifies with the terminal thiol of the silicon-supported intermediate to form a thiol ester capping.

[0009] Preferably, the acrylate binder is compounded from polyurethane acrylate resin and polyester acrylate resin, and has moderate viscosity and film-forming strength.

[0010] Preferably, the co-solvent is compounded from isobornyl acrylate and 1,6-hexanediol diacrylate, which has a good co-solventizing effect and can participate in film formation.

[0011] Preferably, the pigment is selected from inorganic pigments, which can interact with the silicone additive to maintain the bonding strength of the pigment and prevent it from being wiped off.

[0012] A method for preparing a solvent-resistant wipeable UV ink comprises the following steps: premixing an acrylate linker, an organosilicon additive, a leveling agent, a defoamer and a cosolvent, and then adding other components for grinding and dispersion to obtain the solvent-resistant wipeable UV ink.

[0013] Beneficial effects of the present invention: The invention is based on the existing acrylate resin-based UV ink system, and introduces a compound of an organic silicon additive to give the ink excellent solvent resistance while maintaining good adhesion stability; the organic silicon additive is prepared by quaternization reaction of γ-chloropropyltrimethoxysilane and triallylamine to obtain a quaternized matrix, and then a terminal mercapto silicone oil is added to the double bond of the quaternized matrix to introduce a branched organic silicon chain and a terminal mercapto group to obtain a silicon-carrying intermediate, and finally a highly active methacryloyl chloride is esterified with the terminal mercapto group of the silicon-carrying intermediate to form a thiol ester end-capping modification, that is, to obtain the organic silicon additive; in the application process of the ink, the multi-branched silicon chains of the organic silicon additive and the acrylate resin matrix produce a separation effect, It migrates to the surface of the ink layer, forms silicone enrichment in the near-surface layer, and improves the solvent resistance of the ink layer. Compared with existing silicone acrylate additives, silicone additives contain multi-branched silicon chains, and the quaternary ammonium structure in its molecule plays an in-situ modification role, reducing the interfacial tension between the silicon chain and the acrylate matrix, which is beneficial for the silicone additive to fully migrate and spread to the surface of the ink layer. The quaternary ammonium structure promotes the photocuring and cross-linking of acrylates, and then forms a silicon-rich highly cross-linked protective layer on the surface of the ink layer, which effectively resists solvent swelling and friction loss. In addition, the introduced methoxysilane in the silicone additive is coupled with the pigment, filler, etc. in the ink to improve the adhesion strength and swelling and peeling resistance of the ink layer.
