Description

Technical Field

[0001] The invention relates to the technical field of hot stamping printing, and in particular to a high-gloss and high-applicability metallic color carbon ribbon and a preparation method thereof. Background Art

[0002] Traditional metallic ribbons have deficiencies in terms of substrate applicability, glossiness, resolution, and durability. First, the substrate applicability is poor. The adhesion between the substrate and the coating of existing ribbons is limited, and it cannot meet the printing needs of a variety of different materials. It is easy to have problems such as coating shedding. Second, the glossiness is low. Traditional metallic ribbons cannot achieve a high-gloss hot stamping effect. The pattern after transfer is not bright enough and the visual effect is not good. Third, the resolution is limited. Due to the limitations of the structure and formula of each layer, the edges of the printed pattern are not clear enough, and the details are difficult to accurately present, affecting the printing quality. Fourth, insufficient durability: After a certain number of frictions, the metal layer is easy to wear, resulting in the loss of the hot stamping effect. Summary of the invention

[0004] The technical solution of the present invention to solve the above technical problems is as follows:

[0005] The first object of the present invention is to provide a high-gloss and high-applicability metallic color carbon ribbon, comprising a back coating layer, a substrate, a release layer, a dyeing layer, an aluminum plating layer, an isolation layer, and an adhesive layer arranged in sequence from bottom to top;

[0010] The adhesive layer comprises the following raw materials in parts by weight: 10 to 14 parts of a fifth resin, 4 to 7 parts of an auxiliary agent, 1 to 3 parts of a dispersant, 1 to 3 parts of an antioxidant B, and 1 to 3 parts of an antistatic agent B.

[0011] The beneficial effects of the present invention are as follows: the metal color carbon ribbon provided by the present invention improves the substrate applicability, glossiness, resolution and durability of the carbon ribbon by optimizing the formula and structural design of the back coating, release layer, dye layer, metal aluminum plating layer and adhesive layer. The carbon ribbon can achieve high-quality hot stamping printing on a variety of substrates, and the transferred pattern has high glossiness and high resolution, and has good durability in different environments, thereby extending the service life and application range of the product.

[0012] Based on the above technical solution, the present invention can also be improved as follows.

[0013] Furthermore, the substrate includes at least one of polypropylene (PP), polyethylene naphthalate (PEN), polyethylene terephthalate (PET), polyethylene (PE), polyvinyl alcohol (PVA), and polymethyl methacrylate (PMMA).

[0014] Further, the first resin in the back coating layer includes at least one of a thermoplastic resin, a thermoplastic resin silicone modified substance, an organic silicon resin, and a non-silicone resin;

[0015] The catalyst includes at least one of a tin catalyst, an antimony catalyst, and a platinum catalyst; the anchoring agent includes at least one of a silane coupling agent and a titanate coupling agent;

[0016] The silane crosslinking agent includes at least one of hydrogenated silicone oil and methyltriacetoxysilane;

[0017] The release agent A includes at least one of a solid release agent and a liquid release agent.

[0018] Furthermore, the thermoplastic resin includes at least one of polyester resin, polyacrylate resin, polyvinyl acetate resin, styrene acrylate resin, polyurethane resin, polyolefin resin, polystyrene resin, polyvinyl chloride resin, polyether resin, polyamide resin, polyimide resin, polyamideimide resin, polycarbonate resin, polyacrylamide resin, polyvinyl chloride resin, polyvinyl butyral resin, polyvinyl acetal resin, and polyvinyl acetal resin.

[0019] Furthermore, the first resin is a silicone resin.

[0020] Further, the solid release agent includes at least one of polyethylene wax, palmitamide, ethylene bislauric acid amide, behenic acid amide, ethylene bisoleic acid amide, stearic acid amide, ethylene bisstearic acid amide, oleic acid amide, erucic acid amide, oleyl palmitamide, octadecyl stearic acid amide, octadecyl erucic acid amide, pentaerythritol tetrastearate, glyceryl trihydroxystearate, zinc stearate, stearyl zinc phosphate, calcium stearate, and magnesium stearate; the liquid release agent includes at least one of silicone oil, liquid paraffin, chlorinated paraffin, and n-butyl stearate;

[0021] Furthermore, the release agent A is a solid release agent having a melting point of 60° C. or higher and 140° C. or lower.

[0022] The beneficial effects of adopting the above further scheme are: (1) The function of the back coating is to provide smoothness at different printing temperatures, avoid adverse effects such as lateral wrinkles or stickiness during printing, and clean and protect the print head and ensure uniform heat transfer. After the first resin is added to the back coating, in order to further form a more stable three-dimensional network structure, improve the heat resistance of the back coating, improve the adhesion between the back coating and the substrate, and reduce the viscosity at high temperatures, a cross-linking agent and an anchoring agent can be added to the first resin. The cross-linking agent can react with the resin to form a stable three-dimensional network structure, and the anchoring agent can chemically bond with the hydroxyl group on the surface of the substrate, significantly enhancing the adhesion between the back coating and the substrate.

[0023] (2) In order to effectively promote the reaction between the resin and the cross-linking agent and accelerate the curing process, a catalyst can be added to the above-mentioned resin. In order to maintain the excellent smoothness of the carbon ribbon at different printing temperatures during high-speed printing, a certain amount of release agent needs to be added to the back coating. The selection of different melting points can significantly improve the smoothness of the back coating, reduce the friction coefficient between the carbon ribbon and the print head, guide roller and other components, enable the carbon ribbon to move smoothly, reduce paper jams, coating wear and other problems, and ensure the continuity and stability of printing. At the same time, the release agent with a suitable melting point can soften and melt during the printing process, reducing the damage of the solid particles to the aluminum coating due to pressure, which helps to improve the gloss of the printed product.

[0024] Further, the second resin in the dyeing layer includes at least one of a thermoplastic resin, a thermosetting resin, a thermoplastic resin silicone modified substance, and a thermosetting resin silicone modified substance;

[0025] The dye comprises at least one of carbon black dye, acetylene black dye, lamp black dye, cadmium red dye, chrome red dye, vermilion dye, cobalt yellow dye, cadmium orange dye, chrome yellow dye, zinc yellow dye, Naples yellow dye, onion yellow dye, ultramarine dye, vermilion dye, cadmium green dye, chrome green dye, phthalocyanine dye, aluminum pigment, and azo dye;

[0029] Furthermore, the second resin is a hydroxyl polyacrylic resin with a Tg of 80-130° C., a molecular weight of 10,000-100,000, and a hydroxyl value of 50-150.

[0030] Furthermore, the isocyanate compound includes at least one of toluene diisocyanate (TDI), isophorone diisocyanate (IPDI), diphenylmethane diisocyanate (MDI), dicyclohexylmethane diisocyanate (HMDI), hexamethylene diisocyanate (HDI), lysine diisocyanate (LDI), and aromatic isocyanate compounds.

[0031] Furthermore, the isocyanate compound is an aromatic isocyanate compound, and the aromatic isocyanate compound includes but is not limited to 2,4-toluene diisocyanate, 2,6-toluene diisocyanate, toluidine diisocyanate, p-phenylene diisocyanate, and the like.

[0032] The beneficial effects of adopting the above further scheme are as follows: (1) The function of the dyeing layer is to achieve a metallic luster of different colors after the product is printed. By selecting different dyes, the transfer pattern can be given various metallic color effects to meet diverse decorative needs; secondly, it provides a metal deposition carrier for evaporation. Its surface characteristics enable the metal aluminum to be evenly deposited during the evaporation process to form a continuous and dense metal aluminum plating layer, thereby ensuring the quality and stability of the hot stamping effect.

[0033] (2) To ensure that the dyeing layer has appropriate toughness and heat resistance and deformation resistance during the evaporation process. Isocyanate compounds can be added to the above-mentioned resins. In order to achieve metallic luster of different colors after the product is printed, it can be achieved by selecting different dyes. No dye is required to achieve silver metallic luster. A certain amount of wetting agent needs to be added to the coating, which can effectively reduce the surface tension of the dye layer, so that the metal aluminum atoms can better spread and adhere to its surface during the evaporation process, and improve the uniformity and density of the metal aluminum-plated layer. In order to help the coating to flow evenly during the coating process, eliminate surface defects, and ensure the flatness of the dye layer surface, thereby providing a good foundation for metal deposition, making the metal aluminum-plated layer smoother and more uniform, and improving the gloss and texture of the hot stamping pattern, a certain amount of leveling agent needs to be added to the coating.

[0034] Further, the third resin in the isolation layer includes at least one of polyurethane resin, polyester resin, polyacrylic resin, polyvinyl acetate resin, polyvinyl alcohol resin, polyamide resin, polyester, polyolefin resin, polystyrene resin, styrene acrylate resin, polyvinyl chloride resin, water-based polyurethane resin, water-based polyester resin, and water-based polyacrylic resin;

[0035] The defoamer comprises at least one of a silicone defoamer, a surfactant defoamer, a paraffin defoamer, and a mineral oil defoamer;

[0036] The wetting agent B includes at least one of an organic silicon wetting agent, an anionic wetting agent, and a nonionic wetting agent;

[0037] The leveling agent B includes at least one of an acrylic leveling agent, a silicone leveling agent, and a fluorine-modified acrylic leveling agent.

[0038] Furthermore, the third resin is at least one of waterborne polyurethane resin, waterborne polyester resin, waterborne polyacrylic resin and the like.

[0039] The beneficial effects of adopting the above further scheme are as follows: (1) The role of the isolation layer is to isolate the filler particles in the adhesive layer from damaging the aluminum-plated layer. During the use of the carbon ribbon, the filler in the adhesive layer may scratch or corrode the metal aluminum-plated layer due to various factors (such as friction, temperature changes, etc.), affecting the gloss and integrity of the metal aluminum-plated layer. The isolation layer can effectively prevent such damage and maintain the good performance of the metal aluminum-plated layer, thereby ensuring the high gloss of the pattern after printing. At the same time, the synergistic cooperation between this layer of resin and the adhesive layer resin can improve the adaptability of the carbon ribbon to the substrate.

[0040] (2) In order to further eliminate bubbles generated during the preparation and coating of the coating, ensure the flatness and density of the isolation layer, and avoid the influence of bubbles on the performance of the isolation layer, a certain amount of defoaming agent needs to be added to the coating. In order to further reduce the surface tension of the isolation layer coating, improve its wettability to the metal aluminum-plated layer, and ensure good adhesion and coating effects, a certain amount of wetting agent needs to be added to the coating. In order to further reduce and promote the leveling of the coating during the coating process, reduce surface defects, make the isolation layer surface more flat and smooth, and improve the bonding strength with the adhesive layer, a certain amount of leveling agent needs to be added to the coating.

[0041] Further, the fourth resin in the release layer includes at least one of polyurethane resin, polyester resin, polyacrylic resin, polyvinyl acetate resin, polyvinyl alcohol resin, polyamide resin, polyester, polyolefin resin, polystyrene resin, styrene acrylate resin, polyvinyl chloride resin, and EVA resin;

[0042] The release agent B includes at least one of a solid release agent and a liquid release agent;

[0044] The antistatic agent A includes at least one of a sulfuric acid derivative antistatic agent, a phosphoric acid derivative antistatic agent, an amine antistatic agent, a quaternary ammonium salt antistatic agent, an imidazole antistatic agent, and an ethylene oxide derivative antistatic agent.

[0045] Furthermore, the fourth resin is a polyacrylic acid resin with a Tg of 80-130° C. and a molecular weight of 1000-10000.

[0046] Furthermore, the solid release agent includes at least one of polyethylene wax, palmitamide, ethylene bislauric acid amide, behenic acid amide, ethylene bisoleic acid amide, stearic acid amide, ethylene bisstearic acid amide, oleic acid amide, erucic acid amide, oleyl palmitamide, octadecyl stearic acid amide, octadecyl erucic acid amide, pentaerythritol tetrastearate, glyceryl trihydroxystearate, zinc stearate, stearyl zinc phosphate, calcium stearate, and magnesium stearate; the liquid release agent includes at least one of polyethylene wax emulsion, silicone oil, liquid paraffin, chlorinated paraffin, and n-butyl stearate.

[0047] Furthermore, the release agent B is a polyethylene wax emulsion. The polyethylene wax emulsion can reduce the adhesion between the release layer and the upper coating layer, so that the pattern can be smoothly separated from the carbon ribbon, ensuring the integrity and clarity of the transfer. In addition, the wax emulsion can also improve the surface smoothness of the release layer to a certain extent, further enhancing the glossiness.

[0048] The beneficial effects of adopting the above further scheme are: the role of the release layer is to ensure that the release layer can be demoulded smoothly during printing; second, to provide glossiness on the pattern surface after printing. In order to ensure that the release layer has good gloss on the pattern surface after printing, the resin can select a resin with high light transmittance and glossiness. In order to further improve the glossiness of the release layer, it is necessary to improve the demoulding property of the release layer under high temperature printing. A certain amount of release agent needs to be added to the release layer. In order to extend the service life of the product, a certain amount of antioxidant needs to be added to the coating. In order to promptly eliminate the static electricity accumulation generated by the carbon ribbon during the printing process due to friction, and to prevent adverse conditions such as static electricity adsorption, dust absorption, and cremation discharge, a certain amount of antistatic agent can be added to the release layer.

[0049] Furthermore, the fifth resin in the bonding layer is a thermoplastic resin;

[0050] The auxiliary agent includes at least one of inorganic particles, solid lubricants, and liquid lubricants;

[0051] The dispersant includes at least one of a cationic wetting dispersant, an anionic wetting dispersant, a nonionic wetting dispersant, an amphoteric wetting dispersant, and a polymeric super dispersant;

[0052] The antioxidant B includes at least one of a hindered phenol antioxidant, a phosphite antioxidant, a thio antioxidant, a composite antioxidant, and a hindered amine antioxidant;

[0053] The antistatic agent B includes at least one of a sulfuric acid derivative antistatic agent, a phosphoric acid derivative antistatic agent, an amine antistatic agent, a quaternary ammonium salt antistatic agent, an imidazole antistatic agent, and an ethylene oxide derivative antistatic agent.

[0054] Furthermore, the thermoplastic resin is at least one of cellulose-based resin, polyvinyl acetate resin, polyvinyl alcohol resin, polyurethane resin, polyamide resin, polyester, polyacrylate, polyolefin resin, polystyrene resin, styrene acrylate resin, acrylic resin, modified acrylic resin, polyvinyl chloride resin, phenolic terpene resin, rosin ester resin, and polyvinyl chloride resin.

[0055] Furthermore, the fifth resin is at least one of phenolic terpene resin, acrylic resin, modified acrylic resin, and polyvinyl chloride resin.

[0056] Furthermore, the inorganic particles include at least one of silicon dioxide, aluminum oxide, titanium dioxide, molybdenum disulfide, calcium carbonate, and talc; the solid lubricant and the liquid lubricant include at least one of microcrystalline wax, carnauba wax, paraffin, various low molecular weight polyethylene waxes, wood wax, honey wax, spermaceti, wool wax, candelilla wax, vaseline, polyester wax, modified wax, zinc stearate, stearyl zinc phosphate, calcium stearate, magnesium stearate, and flaky kaolin.

[0057] Furthermore, the particle size of the additive is 0.1-0.6 μm, and the specific surface area is 5-10 g / m 2 .

[0058] Furthermore, the dispersant is a polymer type super dispersant.

[0059] The beneficial effects of adopting the above further scheme are as follows: (1) The role of the adhesive layer is to provide basic bonding properties, firmly bonding the metal aluminum-plated layer to the target material through the isolation layer, ensuring that the front layer can be completely transferred to the target material during the printing process, and maintaining a firm adhesion during the subsequent use process to prevent the pattern from falling off or peeling off. To further improve the flatness, barrier properties and adaptability of the adhesive layer on rough surface substrates. During the transfer process, the flat adhesive layer can make the metal aluminum-plated layer and the dye layer better contact with the target material, ensuring the uniformity and integrity of the transfer, and avoiding the situation where the transfer is not local or unclear.

[0060] (2) At the same time, the barrier properties of flaky kaolin can prevent the influence of external substances (such as water vapor, oxygen, etc.) on the performance of the adhesive layer, thereby improving the stability of the product. In addition, the addition of fillers can greatly improve the adaptability of the product on rough substrates, fill the surface of the substrate during printing, and improve the printing effect. In addition, in order to reduce the time and energy required to complete the dispersion process during powder grinding and stabilize the dispersion after grinding, a certain amount of dispersant needs to be added. As such a dispersant, further, in order to inhibit the oxidation reaction of the adhesive layer during storage and use, prevent its performance from deteriorating, such as yellowing, brittleness, etc., extend the service life of the adhesive layer, and thus ensure the stability of the entire metallic color carbon ribbon. In order to reduce the accumulation of static electricity in the adhesive layer during printing, avoid problems such as static electricity adsorption of dust, affecting print quality or causing print head clogging, and improve printing reliability and stability. A certain amount of antistatic agent can be added to the adhesive layer.

[0061] Furthermore, the thickness of the substrate is 4 to 25 μm, the thickness of the back coating is 0.1 to 1.0 μm, the thickness of the release layer is 0.1 to 2 μm, the thickness of the dyeing layer is 0.2 to 5 μm; the thickness of the aluminum plating layer is 0.3 to 0.5 μm; the thickness of the isolation layer is 0.1 to 1.0 μm; and the thickness of the adhesive layer is 0.1 to 1.0 μm.

[0062] A second object of the present invention is to provide a method for preparing a metallic color carbon ribbon with high gloss and high applicability, comprising the following steps:

[0063] S1: back coating liquid: the first resin, catalyst, release agent A, anchoring agent, silane cross-linking agent are dissolved in a solvent to prepare a back coating liquid for standby use; release liquid: the fourth resin, release agent B, antioxidant A, and antistatic agent are dissolved in a solvent and mixed and dissolved to prepare a release liquid for standby use; dyeing liquid: the second resin, isocyanate compound, dye, wetting agent A, and leveling agent A are dissolved in a solvent to prepare a dyeing liquid for standby use; isolation liquid: the third resin, water-based acrylic emulsion, defoamer, wetting agent B, and leveling agent B are dissolved in a solvent and mixed and dissolved to prepare an isolation liquid for standby use; adhesive liquid: the fifth resin, auxiliary agent, dispersant, antioxidant B, and antistatic agent B are dissolved in a solvent and mixed and dissolved to prepare an adhesive liquid for standby use;

[0064] S2: Preparation of back coating layer: apply the back coating liquid on one side of the substrate, and then dry to form the back coating layer; Preparation of release layer: apply the release liquid on the side of the substrate away from the back coating layer, and then dry to form the release layer; Preparation of dyeing layer: apply the dyeing liquid on the side of the release layer away from the substrate, and then dry to form the dyeing layer; Preparation of aluminum-plated layer: use vacuum evaporation to evaporate and deposit metallic aluminum on the side of the dyeing layer away from the substrate to form an aluminum-plated layer; Preparation of isolation layer: apply the isolation liquid on the side of the aluminum-plated layer away from the substrate, and then dry to form an isolation layer; Preparation of bonding layer: apply the bonding liquid on the side of the isolation layer away from the substrate, and then dry to form a bonding layer, so as to obtain a high-gloss and highly applicable metallic carbon ribbon.

[0065] The beneficial effects of the present invention are as follows: the present invention improves the performance of the back coating layer through the synergistic effect of the components in the back coating layer, the cooperation of the isolation layer and the adhesive layer effectively protects the metal aluminum-plated layer and ensures a good bonding effect, and at the same time, the layers work together to achieve the improvement of comprehensive performance such as good smoothness, high gloss, high resolution, high transfer integrity and strong bonding strength.

[0066] Furthermore, the vacuum degree of the vacuum evaporation method in step S2 is 5×10 -3 ~1×10 -2 Pa, evaporation rate is 0.2~0.5nm / s.

[0067] The beneficial effect of adopting the above further scheme is: the main function of the aluminum plating layer is to provide a unique metallic luster and reflective performance, which greatly enhances the decorativeness and visual impact of the pattern. The compactness and flatness of the metal aluminum layer are crucial to ensure the uniformity of the gloss and reflective effect. The compact structure can prevent the aluminum layer from falling off or wearing during use, ensuring the durability of the hot stamping effect; the flat surface can make the light reflect evenly, avoid the appearance of local bright spots or dark spots, and make the pattern more beautiful and delicate. . Generally speaking, the aluminum plating process can adopt a vacuum aluminum plating method, using resistance, high frequency, and electron beam heating to plate aluminum, or vacuum coating technologies such as magnetron sputtering and ion sputtering for aluminum plating. From the perspective of cost and ease of operation, the resistance heating vacuum aluminum plating method is preferred. BRIEF DESCRIPTION OF THE DRAWINGS
