Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heat transfer printing, in particular to a high-adaptability transfer medium, a preparation method and application. BACKGROUND

[0002] As an important means of modern identification and information carrier preparation, heat transfer label printing technology is widely used in industrial automation, product traceability, logistics management and other fields. This technology melts and transfers the color layer on the transfer medium to the surface of the printing substrate through a heat transfer printer, forming the required text, graphics or barcode information.

[0003] However, the main challenge of current heat transfer technology is the contradiction between the highly differentiated application scenarios and the specificity of medium adaptation.

[0004] On the one hand, the printing substrate shows significant diversity, covering two major systems of paper materials and plastic materials, and the plastic substrate is further divided into polyester, polyolefin and other materials with significant differences in chemical structure. The physical and chemical properties of different substrates such as surface energy, thermal stability and chemical compatibility are essentially different, making it difficult for a single transfer medium to achieve stable transfer effect and excellent adhesion performance on different substrates at the same time.

[0005] On the other hand, the heat transfer equipment itself has two mainstream working mechanisms of flat pressure and edge pressure. The two types of printers have fundamental differences in heating element structure, heat conduction mode, and print head pressure distribution, etc. core parameters, which further causes the printing speed range to change from low to high, and this heterogeneity at the equipment level further aggravates the complexity of the performance requirements of the transfer medium.

[0006] The existing technical solutions generally match special transfer media for specific printing materials, and design differentiated products to adapt to different types of printers. This fragmented solution not only increases the production enterprises' formulation research and development cost and inventory management burden, but also brings many practical problems to the end users such as medium selection difficulty, a large number of spare parts, limited use flexibility, etc. It is impossible to meet the urgent needs of modern manufacturing for standardization and generalization of consumables.

[0007] Therefore, how to break through the scene limitation of traditional transfer medium, realize the high adaptability of a single product on multiple types of substrates and multiple types of printers through innovative design of material system, while ensuring the key performance indicators such as transfer speed, image resolution, chemical corrosion resistance and wear resistance, has become the core technical bottleneck restricting the development of heat transfer technology towards high efficiency and intensification.

[0025] The highly adaptable transfer medium of the present invention has a thermoplastic acrylic resin in its color layer 3 that has good pigment dispersibility, can replace conventional dispersants, reduces the raw material cost of color layer 3, and has excellent economic benefits; at the same time, this type of thermoplastic acrylic resin has good transferability, because it requires low energy for transfer, has good fluidity after heating, and has good compatibility with a wide range of substrates, which can effectively improve the transfer on edge press printers and paper-based printing substrates.

[0026] The highly adaptable transfer medium of the present invention has the advantages of fast transfer speed and compatibility with a variety of different substrates. It not only has good transfer effect, but also has good solvent resistance and abrasion resistance.

[0027] Preferably, in the main components, the mass percentage of thermoplastic acrylic resin is 45%-55%, the mass percentage of chloroacetic acid resin is 10%-15%, the mass percentage of chlorinated polypropylene resin is 7%-12%, the mass percentage of pigment is 25%-38%, and the total mass percentage of each component is 100%.

[0028] Preferably, the vinyl chloride-vinyl acetate binary vinyl chloride resin is a vinyl chloride-vinyl acetate binary vinyl chloride resin, in which the mass percentage of vinyl chloride is greater than 85% and the degree of polymerization is greater than 40. This type of vinyl chloride resin has high polarity and vinyl chloride content, providing good substrate compatibility for the color layer 3, enabling the transfer medium to have good transferability on various substrates. At the same time, this type of vinyl chloride resin can also ensure high adhesion of the transferred pattern, ensuring that the pattern has good wear resistance and scratch resistance on various substrates, making the transferred label very reliable.

[0029] Preferably, the chlorinated polypropylene resin contains 18%-30% chlorine by mass. This type of chlorinated polypropylene resin has good compatibility with polyolefin substrates and good solubility in organic solvents. Within the above content range, it can ensure good compatibility with other resins in the color layer 3, thereby giving it good stability in the coating liquid of the color layer 3.

[0030] Preferably, the pigment is carbon black, titanium dioxide, etc., and the particle size of the pigment is 0.1-0.2 μm.

[0031] Preferably, the thickness of the color layer 3 is 0.3-0.6 μm; at this thickness, the pattern printed on various substrates using the transfer medium of the present invention can have good printing quality; if the thickness of the color layer 3 is too thin, it will result in insufficient color density, while if the thickness is too thick, it will result in poor transfer effect and reduced resolution.

[0032] Preferably, the solvent includes methyl ethyl ketone (MEK) and toluene, with the solvent comprising 75-85 parts by mass and the main component comprising 15-25 parts by mass.

[0033] The highly adaptable transfer medium of the present invention also includes a substrate 1, a back coating layer 4 on one side of the substrate 1 and a release layer 2 on the other side, and a color layer 3 on the release layer 2; the thickness of the substrate 1 is 4-10 μm, the thickness of the back coating layer 4 is 0.1-0.5 μm, and the thickness of the release layer 2 is 0.1-0.5 μm.

[0036] The release layer 2 is composed of a water-based wax emulsion, which has good coatability and is less affected by static electricity during the coating process, enabling dense coating. At the same time, the dried wax coating has good peel release properties. The appropriate thickness design ensures that non-transfer areas do not peel off during the transfer process, achieving high-resolution transfer. The low-emulsifier water-based wax emulsion has good resistance to chemical reagents after transfer, and the transferred pattern has good wear resistance and solvent resistance.

[0037] The purpose of the back coating 4 is to prevent adverse effects such as stickiness or wrinkles caused by heating of the temperature-sensitive heating head during heat transfer. Preferably, the back coating 4 includes a main component and auxiliary components. The main component includes one or more of cellulose acetate propionate resin, polyvinyl acetal resin, and polyvinyl butyral resin.

[0038] Further preferred options include high-adhesion resins such as polyester and polyurethane; lubricants such as phosphate esters, zinc stearate, diglyceride, and glyceryl monooleate; self-cleaning fillers such as talc, kaolin, calcium carbonate, aluminum hydroxide, silica, graphite, and boron nitride; and crosslinking agents such as isocyanate compounds.

[0039] The method for preparing the highly adaptable transfer medium of the present invention involves preparing a coating liquid for color layer 3, coating the coating liquid onto release layer 2 and curing it to obtain color layer 3.

[0040] In one specific embodiment, the preparation method of the present invention includes the following specific steps: S1. Prepare the coating liquid for the back coating layer 4, the coating liquid for the release layer 2, and the coating liquid for the color layer 3 respectively.

[0041] The coating liquid for the back coating layer 4 is prepared by dissolving and mixing the main and auxiliary components of the back coating layer 4 with 2-butanone and toluene.

[0042] The preparation method of the release layer 2 coating liquid is to dilute the aqueous wax emulsion to the required solid content range.

[0043] The coating liquid for color layer 3 is prepared by mixing its main components with a solvent of butanone and toluene, then grinding and preparing it into a solution.

[0044] S2. Apply corona discharge to both sides of substrate 1.

[0045] S3. Apply the coating liquid of the back coating layer 4 to one side of the substrate 1 and dry it. Then apply the coating liquid of the release layer 2 to the other side of the substrate 1 and dry it. Finally, apply the coating liquid of the color layer 3 to the release layer 2 and dry it to obtain a highly adaptable transfer medium.

[0046] The method for coating the back coating 4 is as follows: the coating liquid of the back coating 4 is applied to the substrate 1 using a ceramic anilox roller with 200-250 lines and a gravure coating machine, and then dried at 80-100℃. The coating speed is 60-100m / min.

[0047] The coating method for release layer 2 is as follows: the coating liquid of release layer 2 is applied to substrate 1 using a 400-line ceramic anilox roller and a gravure coating machine, and dried at 70-80℃. The coating speed is 60-100m / min.

[0048] The coating method for color layer 3 involves using a 300-340 line ceramic anilox roller and a gravure coating machine to coat the coating liquid of color layer 3 onto release layer 1, and drying it at 80-100℃ at a coating speed of 60-100m / min.

[0049] The highly adaptable transfer media of this invention can be used for thermal transfer flatbed printing on PET, PVC, PP or coated paper, with a printing speed of 12.7 cm / s or higher, or for thermal transfer edge printing on PP film, with a printing speed of up to 60 cm / s.

[0050] The effects of the present invention will be illustrated below through specific embodiments and comparative examples.

[0051] The present invention provides Examples 1-6 and Comparative Examples 1-4.

[0052] The preparation method of the coating liquid for the back coating layer 4 in Examples 1-6 is as follows: Weigh the raw materials according to the following proportions: 60 parts of 2-butanone, 25 parts of toluene, 10 parts of cellulose acetate propionate, 0.5 parts of polyester resin, 0.3 parts of zinc stearate, 0.25 parts of phosphate ester, 0.2 parts of diglyceride, 2 parts of isocyanate, 0.3 parts of talc, 0.2 parts of silica, and 0.3 parts of antistatic agent.

[0053] First, cellulose acetate and polyester resin are dissolved in a mixed solvent of 2-butanone and toluene. Then, zinc stearate, phosphate ester, diglyceride ester, talc, silica and antistatic agent are added and stirred thoroughly for 2 hours. Then, isocyanate is added and stirred for 0.5 hours to obtain the back coating 4 coating liquid.

[0054] In Examples 1-6, the coating liquid formulations for release layer 2 are shown in Table 1: Table 1 In Examples 1-6, the coating liquid formulations for color layer 3 are shown in Table 2: Table 2 The thickness of each coating in Examples 1-6 is shown in Table 3: Table 3 In Comparative Examples 1-4, the composition of the release layer is shown in Table 4, the composition of the color layer is shown in Table 5, and the thickness of each layer is shown in Table 6.

[0055] Table 4 Table 5 Table 6 The media of Examples 1-6 and Comparative Examples 1-4 were tested for print integrity, print tail, abrasion resistance, and alcohol resistance. The specific test methods are as follows: (1) Thermal transfer flatbed printing integrity test: Using a thermal transfer flatbed printer (manufactured by Zebra, model 105SLPlus), transfers were performed on PET, PVC, PP, and coated paper as shown in the image. Figure 2 The lines shown are 0.3pt thick; the printing speed is set to 12.7cm / s.

[0056] The images formed were visually confirmed and evaluated according to the following evaluation criteria. The evaluation results of Examples 1-6 and Comparative Examples 1-4 are shown in Table 7.

[0057] A: No unprinted fine lines or dots were observed in the image; B: Several unprinted thin lines and dots (less than 3) were observed in the image; C: 3-20 or fewer unprinted fine lines and dots were observed in the image; NG: More than 20 unprinted fine lines and dots were observed in the image.

[0058] (2) Thermal transfer edge-press printing integrity test: Using a thermal transfer edge-press printer (manufactured by Markem, model SmartDate®X30), the following prints were transferred onto the PP film: Figure 2 The lines shown are 0.3pt thick; the printing speed was set to 60cm / s. The evaluation results of Examples 1-6 and Comparative Examples 1-4 are shown in Table 7.

[0059] The resulting image, confirmed visually, is evaluated using the following criteria: A: No unprinted fine lines or dots were observed in the image; B: Several unprinted thin lines and dots (less than 3) were observed in the image; C: 3-20 or fewer unprinted fine lines and dots were observed in the image; NG: More than 20 unprinted fine lines and dots were observed in the image.

[0060] (3) Print trail test: Using a label printer (Zebra 105SLPlus), transfer prints were made on a PET substrate. Figure 3 The barcode shown is perpendicular to the printing direction; the printing speed was set to 12.7 cm / s. The test results of Examples 1-6 and Comparative Examples 1-4 are shown in Table 8.

[0061] The resulting image was visually verified and evaluated using a barcode inspector (Honeywell QuickCheck 850) based on the following criteria: A: No trailing was observed in the image; the judgment result based on the barcode inspector is A or B. B: A small amount of trailing is observed in the image. Based on the barcode inspector's judgment result, it is C or D, but it does not affect actual use. NG: Severe trailing, the barcode inspector's judgment result is F or cannot be judged, affecting actual use.

[0062] (4) Abrasion resistance test: Using a label printer (Zebra, model 105SLPlus), transfer is performed on the PET substrate. Figure 3 The barcode is shown; the printing speed is set to 12.7 cm / s. After the barcode transfer is complete, the barcode is then loaded with an 800g weight and wrapped with a lining cloth, and rubbed back and forth 20 times. The test results of Examples 1-6 and Comparative Examples 1-4 are shown in Table 9.

[0063] The resulting image is visually verified and evaluated using the following criteria: A: There is absolutely no image detachment; B: Some images have been missing; C: The image has a lot of missing parts, but it is not a problem in practical use; NG: The image shows significant blemishes, posing practical problems.

[0064] (5) Alcohol resistance test: Using a label printer (Zebra, model 105SLPlus), transfer the label onto PET. Figure 3 The barcode is shown; the printing speed is set to 15.2 cm / s. After the barcode transfer is completed, the barcode is first tested, then a 200g weight is applied to the barcode and wrapped in cotton cloth soaked in 0.5 ml of isopropyl alcohol, and the barcode is rubbed back and forth 10 times. The test results of Examples 1-6 and Comparative Examples 1-4 are shown in Table 10.

[0065] The barcode grade was determined before and after the alcohol resistance test using a barcode inspector (Honeywell Quick Check 850), the grade change was recorded, and the results were evaluated using the following criteria: A: The judgment result based on the barcode inspector has not changed; B: The judgment result based on the barcode inspector was downgraded by one level; NG: The judgment result based on the barcode inspector has been reduced by more than two levels.

[0066] Table 7 Print Integrity Test Table 8 Print trailing test Table 9 Abrasion Resistance Test Table 10 Alcohol Resistance Test The following conclusions can be drawn from the above test results: (1) Examples 1-6 performed well in the print integrity test and were rated A on PET, PP, PVC substrates and edge-pressed printer PP film. In the coated paper test, only Examples 3 and 6 were rated B and the rest were rated A. Comparative Examples 1-2 were rated NG on most substrates due to improper color layer formulation or thickness. Comparative Examples 3-4 were rated B or A on some substrates but the overall stability was insufficient.

[0067] (2) The results of the printing tail test showed that Examples 1, 2, 3, 5, and 6 all obtained Grade A on the PET substrate, while only Example 4 was Grade B. Comparative Examples 1-2 were all Grade NG, Comparative Example 3 was Grade C, and Comparative Example 4 returned to Grade NG. This indicates that the 0.5μm release layer thickness of the comparative examples was too thick, and its 0.2μm color layer was too thin, causing an imbalance in the overall layer structure of the medium, resulting in severe printing tailing.

[0068] (3) In the abrasion resistance test, all of Examples 1-5 were grade A, only Example 6 was grade B, Comparative Examples 1-2 were grade NG, Comparative Example 3 was grade C, and Comparative Example 4 was grade A. This shows that both too high and too low proportions of chlorinated polypropylene resin affect abrasion resistance. In the examples, the ratio of 10-15% combined with the dominant role of 45-55% acrylic resin and the synergistic effect of 7-12% chlorinated polypropylene formed the best abrasion resistance system.

[0069] (4) In the alcohol resistance test, the examples and comparative examples showed more significant differences. Examples 1-5 all obtained grade A, only example 6 obtained grade B, while comparative examples 1-4 were all NG. This shows the decisive advantage of the water-based wax emulsion release layer 2 without emulsifier and the color layer 3 with a specific resin combination in the present invention in terms of chemical corrosion resistance. Even though comparative example 3 was close to the examples in terms of printing integrity, its alcohol resistance was completely ineffective. This proves that the present invention has a significant synergistic effect in the two key technical points of demulsification of release layer 2 and resin ratio optimization of color layer 3.

[0070] In summary, the various embodiments achieved a breakthrough in comprehensive performance by matching the thickness of the release layer 2 (0.2-0.3 μm) with the thickness of the color layer (0.4-0.5 μm), using thermoplastic acrylic resin with a molecular weight of 5000-10000 and a glass transition temperature of 60-80℃ as the pigment dispersion carrier, and by targeting the polyolefin substrate with chlorinated polypropylene with a chlorine content of 18-30%. This resulted in high transfer speed, high resolution, and wear and solvent resistance on various printing substrates and flatbed / edge-press printers. In contrast, the comparative examples generally exhibited systemic failures such as incomplete transfer, heavy tailing, poor wear resistance, and alcohol resistance failure due to deviations in formulation or thickness from the scope of this invention. This demonstrates the high adaptability and superiority of this technical solution.

[0071] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
