Description

Technical Field

[0001] This invention belongs to the field of ink resins, specifically relating to a high-performance UV-LED ink resin, its preparation method, and its application. Background Technology

[0002] The development of the printing industry is inseparable from the development of ink resins. However, traditional ink resins release volatile organic solvents during the drying process, resulting in VOC emissions that affect the natural environment and the health of employees, thus becoming the biggest bottleneck for the development of the printing industry.

[0003] To address environmental concerns, UV inks have been gradually developed. UV inks are ultraviolet light-cured inks, with a drying wavelength range primarily between 350 and 420 nm. UV inks are environmentally friendly, efficient, produce high-quality prints, and are highly adaptable. They have broad application prospects and are widely used in various printing methods, including digital inkjet printing and on various substrates. UV inks have become an important foundation for implementing green printing. However, with practical experience in printing production, some drawbacks of UV inks have also emerged. Among the more prominent issues are: 1. High heat generation and energy consumption. Many UV ink dryers use UV mercury lamps, which generate significant heat, causing substrate deformation and potentially leading to fires with prolonged exposure; 2. High-pressure mercury lamps use mercury as a material, which can pollute the environment. Furthermore, mercury lamp tubes have short lifespans, requiring frequent replacements and resulting in high cumulative costs; 3. After curing, the ink is brittle and lacks toughness. During post-processing such as folding and creasing, the ink breaks, leading to loss of printed images.

[0004] UV-LED inks utilize high-purity, single-wavelength ultraviolet light emitted from their light source. The light energy is highly concentrated in a precise ultraviolet spectral band, ensuring effective curing. Furthermore, the unique formula of LED-UV inks allows for instant curing based on the light source's illumination, with monomers and photoinitiators achieving this effect immediately. Compared to traditional UV curing, UV-LEDs offer several advantages: First, UV-LEDs use LED heating, eliminating heat conduction and preventing substrate deformation or fires due to overheating, resulting in a high safety factor. Second, UV-LED lamps are mercury-free, causing no environmental pollution and providing no glare that could harm the eyes, making them very friendly to operators and the environment. Third, the lifespan of UV-LED light sources is generally more than eight times that of traditional UV light sources, reaching up to 12,000 hours, unaffected by the number of on / off cycles. Finally, UV-LED light sources require no preheating, reaching peak performance instantly upon startup and can be turned off when not in use. However, current UV-LED inks still suffer from issues such as high viscosity, low curing efficiency, and relatively low actual drying results. CN 116478571 A discloses a high-temperature UV-LED embossing ink for glass surfaces and its preparation method, comprising 5-10% solid acrylate, 10-15% active monomer, 50-60% frit, 3-5% photoinitiator, 15-20% high-temperature pigment, and 0.5-1% additives. The resin and monomer prepolymer of this invention can be thoroughly burned through at high temperatures without residue. By sintering the frit, pigment, and ink together on the glass surface, the UV material is completely burned away, leaving the frit and the formed texture. This achieves diverse effects while enhancing the surface's scratch resistance, adhesion, and acid and alkali resistance.

[0005] CN 117210062 A discloses a UV-LED curable inkjet and its preparation method and application. By using a reasonable ratio of photoinitiator (7~10 parts), UV monomer (50~750 parts), oligomer (5~10 parts) and thermosetting agent (2~8 parts), a relatively compact polymer network structure is formed. The selection of UV monomer and oligomer further promotes the mutual attraction between molecules, which increases the surface tension and thus makes the surface tension of the ink higher after curing.

[0006] CN 117089239 A discloses a UV-LED screen printing ink for a light diffusion plate and its preparation method, including modification. The invention comprises polyaldehyde resin, amine-modified epoxy acrylate, acrylate monomer, nano-slurry, photoinitiator, and additives. It exhibits excellent color retention, light diffusion characteristics, excellent rubbing fastness, anti-blocking properties, and adhesion on light diffusion plates made of various materials such as PP and PS.

[0007] Rosin is a low-cost and abundant renewable forest resource. Its main component is resin acid, a monocarboxylic acid with a ternary phenanthrene skeleton and two double bonds, exhibiting good hydrophobicity and a certain degree of rigidity. Esterification, addition, and other modification reactions of the rosin groups can endow it with a variety of properties and applications. Summary of the Invention

[0008] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a high-performance UV-LED ink resin, its preparation method and application.

[0009] To solve the above-mentioned technical problems, the technical solution provided by the present invention is: a high-performance UV-LED ink resin, which is a rosin-modified polyester resin, and its composition (unless otherwise specified, all contents below are expressed as weight) includes: (a) Rosin: 35~50%; (b) Vegetable oil: 5-15%; (c) Alcohols: 20-40%; (d) Saturated acid: 10~15%; (e) Unsaturated acids: 5~10%.

Mix vegetable oil with alcohol and heat to 235-255℃ to carry out alcoholysis reaction to obtain resin A; Step S2. Add rosin, saturated acid and unsaturated acid to resin A obtained in step S1, and heat to 240~265℃ to carry out condensation and esterification reaction to obtain UV-LED ink resin B.

[0011] Preferably, the UV-LED ink resin prepared by the above preparation method is used in ink resins.

[0012] By employing the above method, this invention offers the following advantages: It provides a high-performance UV-LED ink resin. The raw materials used in this resin, rosin and vegetable oil, are natural and renewable resources, abundant and environmentally friendly. The addition of vegetable oil provides good wetting properties and reduces resin viscosity, while the addition of rigid rosin groups provides good wear resistance, corrosion resistance, and excellent gloss. The addition of high-cohesion polyester endows the ink resin with good hardness and toughness. The addition of unsaturated acid increases the curing sites under LED light irradiation, improving the ink curing speed. The UV-LED ink resin obtained by reacting the above raw materials in a reasonable ratio can solve the problems of high viscosity and low curing efficiency in current UV-LED inks. This enables the faster development and expansion of environmentally friendly UV-LED inks, which plays a positive role in promoting national economic development. Attached Figure Description

[0039] Comparative Example 1 The difference between this comparative example and Example 1 is that the amount of semi-drying oil was reduced from 15g of soybean oil to 7.5g, resulting in comparative resin D1.

[0040] Comparative Example 2 The difference between this comparative example and Example 1 is that the amount of rosin and its derivatives was reduced from 150g of hydrogenated rosin to 75g, resulting in comparative resin D2.

[0041] Comparative Example 3 The difference between this comparative example and Example 1 is that the amount of reactant alcohol was reduced from 70g of glycerol to 35g, and the amount of trimethylolpropane was reduced from 10g to 5g, resulting in comparative resin D3.

[0042] Comparative Example 4 The difference between this comparative example and Example 1 is that the amount of saturated acid was reduced from 30g of adipic acid to 15g, resulting in comparative resin D4.

[0043] Comparative Example 5 The difference between this comparative example and Example 1 is that the amount of unsaturated acid was reduced from 25g of fumaric acid to 10g, resulting in comparative resin D5.

[0044] To confirm the prepared resin, ultraviolet-visible spectroscopy (UV-vis) was used to characterize this type of resin. Due to structural similarity, soybean oil, disproportionated rosin, and resin product 1 from Example 1 were selected for testing and analysis. The test results are as follows: Figure 1 , Figure 2 , Figure 3 As shown in the figure, the strong characteristic absorption peaks at 268 and 279 nm, belonging to soybean oil, shifted to 267 and 275 nm after alcoholysis with glycerol and trimethylolpropane, followed by condensation esterification with adipic acid and fumaric acid. This indicates that the strong electron-withdrawing hydroxyl and carboxyl groups of the reacting alcohols and acids attached to the soybean oil chain played a color-reducing role. Furthermore, the figure also shows that the characteristic absorption peak at 259 nm, belonging to disproportionated rosin, shifted to 260 nm after the reaction. This indicates that the long-chain alkyl groups on the molecular chain of soybean oil, after alcoholysis and disproportionated rosin reaction, played a color-enhancing role. Simultaneously, the figure also shows that resin product 1 generated new, smooth characteristic absorption peaks. In summary, a UV-LED ink resin was successfully prepared by alcoholysis of soybean oil with glycerol and trimethylolpropane, followed by condensation esterification with disproportionated rosin, adipic acid, and fumaric acid.

[0045] To further confirm the UV-LED ink resin, Fourier transform infrared spectroscopy (FTIR) was used to characterize this type of resin. Due to structural similarity, soybean oil, disproportionated rosin, fumaric acid, and resin product 1 from Example 1 were selected for testing and analysis. The test results are as follows: Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown in the figure, the characteristic absorption peak of the ester carbonyl group in soybean oil at 1745 cm⁻¹ shifts blue to 1728 cm⁻¹, while the intensity of the characteristic absorption peaks at 729 and 694 cm⁻¹ is significantly weakened or disappears. The characteristic peaks of the carboxyl carbonyl group at 1695 cm⁻¹, belonging to disproportionated rosin, and at 1676 cm⁻¹, belonging to fumaric acid, disappear significantly, forming the ester carbonyl group at 1728 cm⁻¹ belonging to the resin product. The characteristic absorption peaks of the carbon-carbon double bond at 905 and 924 cm⁻¹ belonging to fumaric acid, although red-shifted to 909 and 936 cm⁻¹ after the reaction, are still retained. Due to the participation of trimethylolpropane and glycerol in the reaction, the strong characteristic absorption peak of the hydroxyl group at 3475 cm⁻¹ is retained in the resin product. In summary, a UV-LED ink resin was successfully prepared by alcoholysis of soybean oil with glycerol and trimethylolpropane, followed by condensation esterification with disproportionated rosin, adipic acid and fumaric acid.

[0046] Since the structure and characterization of the resins in other embodiments and comparative examples are similar to those in the product of Example 1 above, they will not be described in detail here.

[0047] In addition, the resin, monomer, and defoamer prepared in the embodiments and comparative examples of the present invention were stirred evenly with a glass rod to prepare a binder. Ground pigment, dispersant, and photoinitiator were added to the prepared binder, and after stirring evenly, UV-LED ink was obtained. The obtained ink was uniformly coated onto paper and cured using a 395nm UV-LED light source. Its performance indicators were tested, and the relevant test results are shown in Table 1.

[0048] Table 1

[0049] The resins prepared in the examples and comparative examples were formulated into UV-LED inks. Tests showed that the inks prepared using the resins in the examples had excellent performance, including moderate viscosity (50.7~68.3 mpa.s), excellent solvent resistance, good gloss (greater than 130), short curing time (not exceeding 0.7 s), strong adhesion (grade 1 to 0-1), moderate film hardness (HB~H), good flexibility (grade 2 to 1-2), and good abrasion resistance (more than 59 abrasion cycles).

[0050] The UV-LED ink prepared in Comparative Example 1 exhibited problems such as increased viscosity (110.5 mPa·s) and prolonged curing time (2.7 s) due to the reduction in soybean oil content.

[0051] The UV-LED ink prepared in Comparative Example 2 exhibited problems such as decreased viscosity (30.3 mPa·s), poorer solvent corrosion resistance (whitening and blistering), reduced gloss (50.1), reduced hardness (3B), and weakened abrasion resistance (more than 35 rub cycles) due to the reduction in the amount of hydrogenated rosin.

[0052] The UV-LED ink prepared in Comparative Example 3 exhibited problems such as decreased viscosity (43.5 mPa·s), prolonged curing time (1.3 s), reduced gloss (105.6), reduced adhesion (level 2), and reduced flexibility (level 3) due to the reduction in the amount of reactive alcohol.

[0053] The UV-LED ink prepared in Comparative Example 4 exhibited several problems due to the reduction in saturated acid content, including decreased viscosity (32.6 mpa.s), prolonged curing time (1.5 s), reduced gloss (89.8), reduced hardness (2B), reduced adhesion (2-3 grade), weakened abrasion resistance (more than 50 abrasion cycles), and reduced flexibility (3-4 grade).

[0054] The UV-LED ink prepared in Comparative Example 5 exhibited several problems due to the reduction in unsaturated acid content, including decreased viscosity (30.8 mpa.s), prolonged curing time (3.6 s), reduced gloss (95.7), reduced hardness (2B), reduced adhesion (2-3 grade), weakened abrasion resistance (more than 46 abrasion cycles), and reduced flexibility (3 grade).

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
