Description

Technical Field

[0001] This invention belongs to the field of printing technology, specifically relating to a water-based, smooth, and highly abrasion-resistant varnish, its preparation method, and its application. Background Technology

[0002] Printing ink is an indispensable material in the printing industry, and with increasing demands for environmental protection and safety, water-based inks, as an environmentally friendly type of ink, are receiving more and more attention. Water-based varnishes, as a key component of water-based inks, provide printed materials with excellent appearance and performance. Water-based varnishes are water-based coatings used in inks primarily to provide smoothness, abrasion resistance, and overall appearance to printed materials.

[0003] Water-based varnishes offer several distinct advantages. First, they use water as the primary solvent, reducing environmental pollution compared to traditional organic solvents. Second, water-based varnishes have a lower impact on human health, meeting modern environmental and health safety requirements. Furthermore, water-based varnishes possess excellent lubrication and gloss properties, making them an ideal component in inks.

[0004] Despite the significant advantages of water-based varnishes among inks, several challenges remain, one of the most prominent being abrasion resistance. Abrasion resistance is crucial for printed materials, especially during high-speed printing where surfaces are easily subjected to friction and wear. Current water-based varnishes have limitations in abrasion resistance; under high abrasion resistance requirements, their protective effect on printed surfaces is not as good as some solvent-based varnishes. Therefore, the development of a new water-based abrasion-resistant varnish is still necessary. Summary of the Invention

[0005] The present invention aims to at least solve one of the aforementioned technical problems existing in the prior art. To this end, the present invention provides a water-based, smooth, and highly abrasion-resistant varnish that, while providing lubrication and improving flowability, forms a robust and smooth surface protective film, thereby enhancing the abrasion resistance of the coating. The interaction of each component and its comprehensive effect on coating performance make this water-based, smooth, and highly abrasion-resistant varnish formulation superior in addressing abrasion resistance issues.

[0006] The present invention also provides a method for preparing a water-based, slippery, and highly abrasion-resistant varnish.

[0007] This invention also provides an application of a water-based, smooth, and highly abrasion-resistant varnish in high-speed printing.

[0008] The first aspect of the present invention provides a water-based, smooth, and highly abrasion-resistant varnish, comprising, by weight:

[0009] Water-based wax emulsion: 20 to 45 parts,

[0010] Resin solution: 50 parts

[0011] Defoamer: 0.1 to 0.5 parts

[0012] Wetting agent: 2 to 10 parts

[0013] Dipropylene glycol methyl ether: 1 to 3 parts

[0014] Dispersant: 0.1 to 2 parts

[0015] Lubricant: 0.1 to 2 parts

[0016] Water: 5 to 10 parts.

[0017] The aqueous wax emulsion contains palm wax and beeswax, and the mass ratio of palm wax to beeswax is 1:1 to 3.

[0018] One of the technical solutions of this invention regarding a water-based, smooth, and highly abrasion-resistant varnish has at least the following beneficial effects:

[0019] Aqueous wax emulsions are emulsions containing wax microparticles. While aqueous wax emulsions offer advantages in providing lubrication and a certain degree of wear resistance, several drawbacks exist. First, because the wax microparticles in aqueous wax emulsions are typically small and dispersed in water, traditional methods of improving wear resistance often rely on larger or specially shaped particles to form a more robust protective film on the surface. The small particles in aqueous wax emulsions are less likely to form a structure with the same effect. Second, the water-based nature of the wax emulsion can affect the uniformity of the coating during application. Traditional solvent-based lubricants and wear-resistant additives are easier to distribute uniformly in organic solvents, while uniform distribution in aqueous systems may require more refined processes. Third, while the components of wax emulsions generally have good compatibility with other water-based components, compatibility issues may exist with some traditional organic solvent-based wear-resistant additives, limiting the application of some traditional additives in aqueous wax emulsions. Fourth, the wetting and adhesion properties of wax emulsions may differ from those of traditional wear-resistant additives, resulting in variations in the performance of the protective film formed on the surface.

[0020] This invention relates to a water-based, smooth, and highly abrasion-resistant varnish. Through optimized formulation, a water-based, smooth, and abrasion-resistant varnish has been obtained. Specifically:

[0021] The water-based wax emulsion of this invention contains palm wax and beeswax. Beeswax generally has lubricating properties, while palm wax may provide better abrasion resistance. The properties of the water-based wax emulsion can be adjusted by selecting palm wax and beeswax for blending. The microparticles in the wax emulsion can form a robust protective film, improving the abrasion resistance of the coating. Palm wax and beeswax themselves have good lubricity, which helps to improve the smoothness of the coating.

[0022] The addition of resin liquid can enhance the adhesion of the coating and ensure that the varnish adheres firmly to the surface of the printed material.

[0023] Defoamers help prevent bubbles from forming during coating, keeping the coating smooth.

[0024] Wetting agents can improve the flowability of coatings, ensure uniform coating distribution, and help form a more robust surface.

[0025] Dipropylene glycol methyl ether helps to disperse pigments evenly and maintain the consistency of color on the surface of printed materials.

[0026] Using water as a solvent reduces the use of organic solvents and improves the environmental friendliness of the product.

[0027] Dispersants can ensure that pigments are evenly distributed in coatings, enhancing the overall quality of the coating.

[0028] The addition of slip agents can significantly improve the gloss of the coating, making the surface of printed materials smoother.

[0029] The water-based, smooth, and highly abrasion-resistant varnish of this invention, by comprehensively utilizing the above-mentioned components, can form a robust and smooth surface protective film while providing lubrication and improving fluidity, thereby enhancing the abrasion resistance of the coating. The interaction of each component and its combined effect on coating performance make this water-based, smooth, and highly abrasion-resistant varnish formulation superior in addressing abrasion resistance issues.

[0030] According to some embodiments of the present invention, the aqueous wax emulsion contains, by weight:

[0031] Carnauba wax: 1 part

[0032] Beeswax: 1 to 3 parts

[0033] Emulsifier A: 3 to 5 parts

[0034] Emulsifier B: 1 to 3 parts

[0035] Stabilizer: 1 to 3 parts

[0036] Water: 10 to 100 parts

[0037] The emulsifier A is at least one of octanol polyoxyethylene ether and polyethylene ether.

[0038] The emulsifier B is a fatty alcohol ether.

[0039] The stabilizer is at least one of polyacrylate and polyacrylate.

[0040] Water-based wax emulsions contain carnauba wax and beeswax. Beeswax has excellent lubricity, thus forming a smooth film on the coating surface, improving the surface smoothness of printed materials or coatings. Beeswax also provides a certain degree of abrasion resistance to the coating, reducing surface wear and scratches. Beeswax often has a light yellow tint, producing a gentle color effect in some applications. Carnauba wax is an extremely hard wax that provides excellent abrasion resistance, making it a more suitable choice for applications requiring even greater abrasion resistance, such as printing inks. Carnauba wax also provides a glossy surface to coatings or printed materials.

[0041] The combined use of emulsifiers A and B helps to evenly disperse wax particles in water, preventing aggregation or sedimentation and improving coating uniformity. It also increases emulsion stability, preventing stratification or phase changes during storage or use. Furthermore, by aiding in the formation of a uniform film, the combined use of emulsifiers A and B helps improve coating lubricity, resulting in a smoother printed surface. The combined use of emulsifiers A and B also contributes to coating uniformity, improving coating flow and making the coating process smoother.

[0042] The stabilizer is at least one of polyacrylate and polyacrylate, both of which have good dispersibility and adsorption properties, which helps to maintain the dispersion state of the wax particles.

[0043] According to some embodiments of the present invention, the resin liquid is at least one of acrylic resin liquid and polyurethane resin liquid, in parts by weight.

[0044] Both acrylic resin and polyurethane resin have good adhesion and abrasion resistance, which can improve the adhesion of water-based slippery and abrasion-resistant varnishes to the substrate, while increasing the abrasion resistance of the coating and making it more durable.

[0045] According to some embodiments of the present invention, the defoamer is at least one of fatty alcohol polyoxyethylene ether and silicone oil, in parts by weight.

[0046] By reducing or eliminating foam, fatty alcohol polyoxyethylene ethers and silicone oils help improve coating uniformity, ensuring that the coating forms a smooth and uniform surface on the substrate.

[0047] According to some embodiments of the present invention, the wetting agent is at least one of polymethyl polyoxyethylene ether and polyethylene glycol ether, in parts by weight.

[0048] Polymethyl polyoxyethylene ether and polyethylene glycol ether exhibit good wetting properties, which helps the coating adhere better to the substrate surface and form a uniform film. Good wetting properties can also improve the surface quality of the coating, making it smoother and more uniform, and improving gloss and appearance. By improving wetting properties, the wetting agent can indirectly improve abrasion resistance, allowing the coating to be more evenly distributed on the substrate and reducing the possibility of wear and peeling.

[0049] According to some embodiments of the present invention, the dispersant is at least one of octylphenol polyoxyethylene ether and polyacrylamide, in parts by weight.

[0050] The choice of dispersant is crucial to the stability of the emulsion system. Octylphenol polyoxyethylene ether and polyacrylamide dispersants help maintain the stability of aqueous wax emulsions, preventing phase separation or precipitation. By ensuring uniform dispersion of wax particles, dispersants help improve the adhesion between the coating and the substrate, resulting in a stronger bond between the coating and the substrate surface. The use of dispersants also helps prevent the agglomeration of wax particles, allowing them to be more evenly distributed in the aqueous wax emulsion, improving the uniformity and transparency of the coating.

[0051] According to some embodiments of the present invention, the slip agent is at least one of polyvinyl ketone and microcrystalline wax, in parts by weight.

[0052] Polyvinyl ketone (PVP) and microcrystalline wax slip agents possess excellent lubricity, forming a thin, uniform lubricating film on the coating surface, improving its smoothness and feel. They also reduce friction, enhance the coating's wear resistance, and extend its service life. Because the slip agent forms a thin film on the coating surface, it provides a soft, slippery feel, improving the product's tactile experience. Furthermore, the addition of PPVP and microcrystalline wax slip agents helps reduce the coefficient of friction on the coating surface, especially when the contact area is large. The lubricating effect of the slip agent reduces the adhesion of dust and stains, thereby improving the coating's stain resistance.

[0053] A second aspect of the present invention provides a method for preparing the water-based slippery and highly abrasion-resistant varnish of the present invention, the method comprising the following steps: mixing the water-based wax emulsion, resin liquid, defoamer, wetting agent, dipropylene glycol methyl ether, dispersant, slippery agent and water in a specified ratio.

[0054] One technical solution of the present invention relating to the preparation method of water-based slippery and highly abrasion-resistant varnish has at least the following beneficial effects:

[0055] The preparation method of the present invention does not require expensive equipment and complex process control, the reaction conditions are not harsh, the raw materials are readily available, the production cost is low, and it is easy to industrialize.

[0056] A third aspect of the invention provides the application of water-based, slippery, and highly abrasion-resistant varnishes in high-speed printing.

[0057] The present invention relates to a technical solution for the application of water-based, smooth, and highly abrasion-resistant varnish in high-speed printing, which has at least the following beneficial effects:

[0058] In high-speed printing, paper needs to pass through the printing press at a faster speed, making paper handling and feeding more difficult and prone to wear, which can affect print quality. The use of abrasion-resistant varnishes helps reduce friction and improves the sliding properties between the paper and the printing press, thus increasing printing speed in high-speed printing. Reduced friction also helps lower energy consumption and improve production efficiency. The lubricating and abrasion-resistant components in abrasion-resistant varnishes can form a protective film on the mechanical parts of the printing press, reducing wear and fatigue and extending the life of the printing press. Furthermore, the use of abrasion-resistant varnishes can improve the surface smoothness and appearance of printed materials, reducing paper burrs and other defects generated during printing, and improving print quality. The components in abrasion-resistant varnishes can form a uniform protective film, improving the abrasion resistance of printed materials, making them more durable and adaptable to high-frequency printing processes. The lubricating effect of abrasion-resistant varnishes helps reduce friction between the paper and the printing press, thereby reducing paper breakage and improving production efficiency. The use of lubricants and slip agents in abrasion-resistant varnishes helps reduce dust generated during the printing process, improving the printing environment and operating conditions. The use of abrasion-resistant varnish can reduce uneven distribution of coatings in high-speed printing, and improve the stability and consistency of printing.

[0059] According to some embodiments of the present invention, the printing speed of the high-speed printing is ≥100 meters / min. Detailed Implementation

[0060] The following are specific embodiments of the present invention, and the technical solutions of the present invention will be further described in conjunction with the embodiments, but the present invention is not limited to these embodiments.

[0061] In some embodiments of the present invention, a water-based, smooth, and highly abrasion-resistant varnish is provided, comprising, by weight:

[0070] The water-based wax emulsion contains palm wax and beeswax, with a mass ratio of palm wax to beeswax of 1:1 to 3.

[0106] It is understood that the preparation method of the present invention does not require expensive equipment and complex process control, the reaction conditions are not harsh, the raw materials are readily available, the production cost is low, and it is easy to industrialize.

[0107] In some embodiments of the present invention, the application of water-based, slippery, and highly abrasion-resistant varnishes in high-speed printing is provided.

[0108] Understandably, in high-speed printing, paper needs to pass through the printing press at a faster speed, making paper handling and feeding more difficult and prone to wear that can affect print quality. The use of abrasion-resistant varnishes helps reduce friction and improves the sliding properties between the paper and the printing press, thus increasing printing speed in high-speed printing.

The use of lubricants and slip agents in abrasion-resistant varnishes helps reduce dust generated during the printing process, improving the printing environment and operating conditions. The use of abrasion-resistant varnish can reduce uneven distribution of coatings in high-speed printing, and improve the stability and consistency of printing.

[0109] In some embodiments of the present invention, the printing speed of high-speed printing is ≥100 meters / min.

[0110] The aqueous dispersion in water-based, slip-resistant, high-abrasion-resistant varnishes allows the coating to dry more quickly after printing. This helps prevent blurring or sticking of printed materials due to incomplete ink drying during high-speed printing. Furthermore, the components in water-based, slip-resistant, high-abrasion-resistant varnishes, particularly the resin and slip agents, contribute to the formation of a smooth and glossy surface. This enhances the appearance quality of printed materials, making them more attractive.

[0111] Understandably, water-based, high-abrasion-resistant varnishes, being water-based, emit lower levels of volatile organic compounds (VOCs) compared to solvent-based varnishes, thus reducing environmental impact and making them more environmentally friendly. Furthermore, the components in water-based, high-abrasion-resistant varnishes, such as wax emulsions and resin solutions, can form a uniform coating and provide a protective film, thereby improving the abrasion resistance of printed materials and adapting to the frequent contact and wear in high-speed printing. The use of water-based, high-abrasion-resistant varnishes also helps reduce dust generated during the printing process, maintaining the cleanliness of the printing press and printed materials, and reducing machine maintenance needs. The wetting agents and slippers in the varnish form a lubricating film on the coating surface, helping to reduce friction between paper and printing machinery parts, improving paper transfer and the operational stability of the printing press.

[0112] In addition, water-based, slippery, and highly abrasion-resistant varnishes can provide a uniform coating in high-speed printing, which helps maintain the stability of the printing press and reduces problems caused by uneven coating distribution.

[0248] Performance testing

[0249] Water-based varnishes from Examples 1 to 3 and Comparative Examples 1 and 2 were used to form ink layers under the same conditions, and the gloss, abrasion resistance, and smoothness of the ink layers were tested.

[0250] The gloss test was conducted in accordance with GB / T 7706-2008 "Relief Printing".

[0251] The abrasion resistance test is conducted according to the test conditions for ink layer abrasion resistance in GB / T 7706-2008 "Relief Printing" 6.8. The abrasion resistance of water-based varnish is judged by whether the ink layer color is rubbed off, and the number of rubbings when the ink layer color is rubbed off can be recorded.

[0252] The slip properties of the ink were tested using a coefficient of friction meter.

[0253] The test results are shown in Table 1.

[0254] Table 1

[0255] Glossiness / ° Abrasion resistance / times coefficient of friction Example 1 62 515 0.2 Example 2 64 525 0.18 Example 3 65 530 0.15 Comparative Example 1 64 490 0.25 Comparative Example 2 63 485 0.23

[0256] As can be seen from the test results in Table 1, the water-based varnish of the present invention has good gloss, and is also smooth and wear-resistant.

[0257] The water-based wax emulsion of this invention contains palm wax and beeswax. Beeswax generally has lubricating properties, while palm wax may provide better abrasion resistance. The properties of the water-based wax emulsion can be adjusted by selecting palm wax and beeswax for blending. The microparticles in the wax emulsion can form a robust protective film, improving the abrasion resistance of the coating. Palm wax and beeswax themselves have good lubricity, which helps to improve the smoothness of the coating.

[0258] Furthermore, beeswax has excellent lubricating properties, thus forming a smooth film on the coating surface, improving the surface smoothness of printed materials or coatings. Beeswax can also provide coatings with a certain degree of abrasion resistance, reducing the degree of surface wear and scratches. Beeswax often has a light yellow tint, which can produce a gentle color effect in some applications. Carnauba wax is a wax with extremely high hardness, providing excellent abrasion resistance. For applications requiring even greater abrasion resistance, such as printing inks, carnauba wax is a more suitable choice. Carnauba wax can also provide a better gloss surface for coatings or printed materials.

[0259] The present invention has been described in detail above with reference to the embodiments. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
