Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of black card paper printing, in particular to a black card paper anti-ink corrosion printing method and a black card paper product. BACKGROUND

[0002] With the rapid development of economic cross-regional cooperation and the increasing improvement of people's living standards today, people have higher requirements for high-quality surface decoration. In packaging design, black card paper is a kind of main circulating packaging material in modern times. Black card paper is a kind of dyeing offset paper with high stiffness, thickness and large basis weight, and has obvious paper fibers on the surface, which is suitable for paper mobile phone packaging boxes, tea boxes, and collectible packaging boxes. In addition, black card paper can also be used to make folders, writing boards and other stationery. The process on the surface of black card paper on the market mainly is UV and gold stamping, which cannot meet people's needs. In the existing technology, printing on black card paper is to print a layer of white ink first and then print graphics and text on the white ink. Although this way, the graphics and text on the black card will appear discoloration, blackening and fading after a period of use. SUMMARY

[0003] Therefore, it is necessary to provide a black card paper anti-ink corrosion printing method and a black card paper product which can avoid discoloration, blackening and fading of graphics and text during use.

[0004] In a first aspect, the present application provides a black card paper product, comprising black card paper and a styrene-acrylic emulsion touch layer formed on the black card paper, wherein the styrene-acrylic emulsion touch layer is prepared by curing the following components: styrene-acrylic emulsion, water-based resin, additive and water.

[0005] In one embodiment, the styrene-acrylic emulsion touch layer comprises the following components in mass percentage: styrene-acrylic emulsion 20%-60%, water-based resin 5%-15%, additive 1%-2%, and water in the balance.

[0006] In one embodiment, the black card paper product further comprises an ink layer formed on the surface of the styrene-acrylic emulsion touch layer.

[0007] In one embodiment, the ink layer is an environmentally friendly water-based ink layer.

[0008] In one embodiment, the ink layer comprises the following components in mass percentage: water-based resin 20%-25%, additive 1%-3%, pigment 25%-30%, connecting material 2%-5%, and water in the balance.

[0009] In one embodiment, the black card paper contains black fillers, the black fillers contain carbon elements, and the proportion of the black fillers is 60%-70%.

[0010] In one embodiment, the amount of the mixed components of the styrene-acrylic emulsion tactile layer applied to the black cardboard is 4–6 g / m². 2 .

[0011] In one embodiment, the thickness of the ink layer is 1-2 μm.

[0012] In one embodiment, the additives include at least one of dispersants, leveling agents, slip agents, defoamers, antislip agents, matting agents, plasticizers, abrasion resistant agents, and patterning agents.

[0013] Secondly, this application provides a method for printing anti-corrosion ink on black cardstock, comprising the following steps:

[0014] Provide a black cardstock;

[0015] A styrene-acrylic emulsion tactile layer is formed on the surface of black cardboard, wherein the styrene-acrylic emulsion tactile layer is prepared by curing the following components: styrene-acrylic emulsion, water-based resin, additives and water;

[0016] An ink layer is formed by printing on the styrene-acrylic emulsion tactile layer.

[0017] The aforementioned finished black cardboard product utilizes a styrene-acrylic emulsion tactile layer formed on its surface. This styrene-acrylic emulsion tactile layer is prepared from the following components: styrene-acrylic emulsion, water-based resin, additives, and water. Upon curing, the resulting coating exhibits both waterproof and ink-resistant properties due to the styrene-acrylic emulsion, while the cured coating film from the water-based resin demonstrates corrosion resistance, resulting in excellent anti-corrosion performance. The applicant's research has revealed that black cardboard, containing a large amount of black filler primarily composed of carbon elements (60%-70%), is highly acidic, causing it to corrode the surface ink over time. This application addresses this issue by forming a styrene-acrylic emulsion tactile layer on the black cardboard surface, which provides excellent waterproof and ink-resistant properties, effectively separating the ink from the black cardboard and preventing corrosion. The styrene-acrylic emulsion tactile layer also features a matte finish, good abrasion resistance, excellent anti-sticking properties, environmental friendliness, and a smooth feel. Comparative testing revealed that applying a layer of treatment to the paper surface creates a barrier between the ink and the black cardstock. This barrier provides waterproofing and corrosion resistance. The cured coating of the tactile oil further refines and smooths the paper surface. The tactile oil contains styrene-acrylic emulsion and water-based resin. The styrene-acrylic emulsion provides waterproofing and ink resistance, while the cured coating of the water-based resin provides corrosion resistance, resulting in excellent corrosion resistance. The applicant addresses the technical problem of ink deterioration on black cardstock by coating it with a layer of tactile oil, ensuring the quality of printed materials and preserving the original effect of the ink. This prevents discoloration, blackening, or fading of the ink on the black cardstock after printing. BRIEF DESCRIPTION OF DRAWINGS

However, the present application can be implemented in many different forms, and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive. The present application can be implemented in many different ways from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application, therefore the present application is not limited to the specific embodiments disclosed below. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as understood by those skilled in the art to which the present application belongs. The terms used herein are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0020] In a first aspect, the present application provides a black card paper finished product, comprising a black card paper and a styrene-acrylic emulsion touch layer formed on the black card paper, wherein the styrene-acrylic emulsion touch layer is prepared by curing the following components: styrene-acrylic emulsion, water-based resin, auxiliary agent and water.

[0021] The black card paper product is formed by forming a styrene-acrylic emulsion touch layer on the surface of the black card paper, wherein the styrene-acrylic emulsion touch layer is prepared from the following components: styrene-acrylic emulsion, water-based resin, additives and water. Thus, the coating formed after curing has the functions of waterproofing and ink-proofing. The styrene-acrylic emulsion has the functions of waterproofing and ink-proofing, the coating film formed after curing of the water-based resin has the function of corrosion resistance, and excellent corrosion resistance is formed. The applicant found that the black card paper contains a large amount of black filler, which is mainly composed of carbon elements, and accounts for 60%-70% on the black card paper, so that the paper is strongly acidic, and the black card paper will corrode the surface ink after a long time. The application forms a styrene-acrylic emulsion touch layer on the surface of the black card paper, which has good waterproof and ink-proofing effect, and can better separate the ink and the black card paper, thereby avoiding the corrosion of the black card paper to the ink. The styrene-acrylic emulsion touch layer has the characteristics of lusterless, good wear resistance, excellent anti-sticking flower property, environmental protection, delicate touch and the like. Through comparison and test results, a layer of treatment is made on the surface of the paper to form an obstacle between the ink and the black card paper, which has the functions of waterproofing and corrosion resistance. The coating film formed after curing of the touch oil makes the surface of the paper more delicate and smooth. The touch oil contains styrene-acrylic emulsion and water-based resin. The styrene-acrylic emulsion has the functions of waterproofing and ink-proofing, and the coating film formed after curing of the water-based resin has the function of corrosion resistance, forming excellent corrosion resistance. The applicant coats a layer of touch oil on the black card paper to solve the technical problem of ink deterioration on the black card paper, to ensure the quality of the printed matter, so that the ink printed on the black card paper can well ensure the effect of the ink itself. Thus, the black card paper after printing ink has the problems of discoloration, blackening and lightening of the ink image.

[0022] In one embodiment, the black card paper contains black filler, the black filler includes carbon elements, and the black filler accounts for 60%-70%. In other words, the black card paper product of the application is more preferably used for black card paper containing carbon elements, and the black card paper with black filler accounting for 60-70%. Thus, the traditional direct printing of ink on the surface of the black card paper is corroded due to the acidity of the black card paper. The application forms a styrene-acrylic emulsion touch layer on the surface of the black card paper, which can better play the functions of waterproofing and ink-proofing, thereby better isolating the ink and the black card paper, and ensuring that the ink image does not easily appear discoloration, blackening and lightening during long-term use of the black card paper after printing ink.

[0023] In one embodiment, the styrene-acrylic emulsion touch layer includes the following components by mass percentage: styrene-acrylic emulsion 20%-60%, aqueous resin 5%-15%, auxiliary agent 1%-2%, and water balance. In one embodiment, the auxiliary agent includes at least one of dispersant, leveling agent, slip agent, defoaming agent, anti-slip agent, matting agent, plasticizer, wear-resistant agent, and pattern agent. It should be noted that in this embodiment, the auxiliary agent used can be some commonly used auxiliary agents in the field of printing ink technology. Dispersant, leveling agent, slip agent, defoaming agent, anti-slip agent, matting agent, plasticizer, wear-resistant agent, and pattern agent can also use some known agents in the art. This application will not be described here. For example, dispersant: it is a functional polymer or functional small molecule compound, mainly used for the dispersion of pigments in the system, which can improve the coloring power, shorten the grinding time of the ink, increase the stability of the system, prevent color floating and blooming, etc. Leveling agent: mainly acts on the leveling and continuity of the polymeric silicone ink layer, and enhances the flow performance of the ink. Slip agent: makes the surface of the printed ink layer smooth and wear-resistant. Defoaming agent: used to prevent and eliminate bubbles during the production and use of the ink. Anti-slip agent: used for printing the surface of packaging with anti-slip requirements, especially the surface of cartons and packaging bags. Matting agent: used for printing packaging with matt and matt requirements. Plasticizer: used for softening the ink layer to prevent cracking of the printed ink layer. Wear-resistant agent: used to provide the wear resistance of the ink layer surface and the adaptability of the scraper. Pattern agent: used to produce different cracking lines. In this embodiment, by including the following components by mass percentage in the styrene-acrylic emulsion touch layer: styrene-acrylic emulsion 20%-60%, aqueous resin 5%-15%, auxiliary agent 1%-2%, and water balance, the styrene-acrylic emulsion touch layer prepared in this way can play a good anti-film and anti-corrosion effect, so that the black card paper does not easily have problems such as discoloration, blackening, and lightening of the ink pattern after printing. Especially, by using styrene-acrylic emulsion 20%-60% and aqueous resin 5%-15% in combination, the coating formed after curing can better play a hindering effect, which has the effects of water resistance and corrosion resistance, and the coating film of the touch oil after curing makes the surface of the paper more delicate and smooth. The touch oil contains 20%-60% styrene-acrylic emulsion and 5%-15% aqueous resin, which can simultaneously consider the effects of water resistance and ink resistance and corrosion resistance when used in combination, forming excellent corrosion resistance.

[0024] In one embodiment, the amount of oiling of the mixed components of the styrene-acrylic emulsion touch layer on the black card paper is 4-6 g / m 2 . In this way, the styrene-acrylic emulsion touch layer with the above oiling amount can better consider the effects of water resistance and ink resistance and corrosion resistance, forming excellent corrosion resistance, and the thickness of the styrene-acrylic emulsion touch layer can be relatively thin. The applicant found that when the oiling amount is less than 4 g / m 2If the cured adhesive layer is insufficient, it may result in loose adhesion, affecting the corrosion resistance. This can lead to potential problems such as discoloration, blackening, and fading of the ink even after prolonged use. The amount of ink applied to the black cardboard using the mixed components of the styrene-acrylic emulsion tactile layer is 4-6 g / m². 2 This means it can provide good long-term corrosion protection. However, when the oil application rate is greater than 4g / m... 2 At this time, there may be a problem with the coating not being tight enough, which could affect the ink's effect. When the mixed components of the styrene-acrylic emulsion tactile layer are applied to the black cardstock at a rate of 4-6 g / m²... 2 At the same time, it can better balance the anti-corrosion effect and the ink printing effect.

[0025] In one embodiment, the viscosity of the mixed components of the styrene-acrylic emulsion tactile layer is 50–80 Pa·s; solid content is 29–33 wt%; pH value is 6.5–8.5; the anilox roller used for printing is 120–140 lines; the temperature is 80–135°C; and the oil application rate is 4–6 g / m³. 2 In this way, the mixed components of the styrene-acrylic emulsion tactile layer can be well formed after curing to form the styrene-acrylic emulsion tactile layer, and the anti-corrosion effect is good.

[0026] In one embodiment, the finished black cardboard also includes an ink layer formed on the surface of the styrene-acrylic emulsion tactile layer. For example, the ink layer is an environmentally friendly water-based ink layer. For example, the ink layer comprises the following components in parts by weight: 20%-25% water-based resin, 1%-3% additives, 25%-30% pigment, 2%-5% binder, and the balance being water. Thus, using the above-mentioned ink layer, an ink layer can be effectively printed on the surface of the cured coating of the styrene-acrylic emulsion. In this embodiment, the additives include at least one of dispersants, leveling agents, slip agents, defoamers, anti-slip agents, matting agents, plasticizers, abrasion resistant agents, and patterning agents. Specifically, the binder, also known as a tie or adhesive, is the fluid component of the ink and a major component of ink printing. It suspends pigments or dyes in the binder, allowing them to be coated onto the surface of the printing material. Simultaneously, the binder also protects the pigments, preventing them from settling or separating. The binder also has a significant impact on the drying speed, adhesion, water resistance, lightfastness, and heat resistance of printed materials. The binder used in this application can be some common binders in the ink industry, which will not be elaborated upon here. In one embodiment, the thickness of the ink layer is 1-2 μm. Thus, using the above-mentioned ink layer, especially the mixed components combined with the styrene-acrylic emulsion tactile layer, the ink application rate on the black cardstock is 4-6 g / m². 2 This means it can provide good long-term corrosion protection.

[0027] In one embodiment, the viscosity of the mixed components of the aqueous ink layer is 10-25 Pa.S; the solid content is 35-40 (wt%); the pH value is 8.5-9; the printing anilox roll is 300-600 lines; the temperature is 15-40℃; and the thickness is 1-2 μm. In this way, the ink layer can be formed well.

[0028] The black card paper product is formed by forming a styrene-acrylic emulsion touch layer on the surface of the black card paper. The styrene-acrylic emulsion touch layer is prepared from the following components: styrene-acrylic emulsion, aqueous resin, additives and water. After curing, the coating layer formed by the styrene-acrylic emulsion has water and ink resistance, the coating film formed by the aqueous resin after curing has corrosion resistance, and excellent corrosion resistance is formed. The applicant found that the black card paper is strongly acidic due to the large amount of black filler, which is mainly composed of carbon elements, accounting for 60%-70% of the black card paper, so that the paper will corrode the surface ink over time. The application forms a styrene-acrylic emulsion touch layer on the surface of the black card paper, which has good water and ink resistance, and can well separate the ink and the black card paper, thereby avoiding the corrosion of the black card paper on the ink. The styrene-acrylic emulsion touch layer has the characteristics of luster, good wear resistance, excellent anti-sticking flower performance, environmental protection, delicate touch and the like. Through comparison and test results, a layer of treatment is made on the surface of the paper to form an obstacle between the ink and the black card paper. The obstacle has water and corrosion resistance, and the coating film of the touch oil after curing makes the surface of the paper more delicate and smooth. The touch oil contains styrene-acrylic emulsion and aqueous resin, the styrene-acrylic emulsion has water and ink resistance, the coating film formed by the aqueous resin after curing has corrosion resistance, and excellent corrosion resistance is formed. The applicant coats a layer of touch oil on the black card paper to solve the technical problem of ink deterioration on the black card paper, to ensure the quality of the printed matter, so that the ink printed on the black card paper can well ensure the effect of the ink itself. Thus, the black card paper after printing ink can avoid problems such as discoloration, blackening and lightening of the ink image.

The styrene-acrylic emulsion has the effects of waterproofing and ink-proofing, the coating film of the water-based resin after curing has the effect of corrosion resistance, and excellent corrosion resistance is formed. The applicant found that the black card paper contains a large amount of black filler, which is mainly composed of carbon elements, accounting for 60%-70% on the black card paper, so that the paper is strongly acidic, and the black card paper will corrode the surface ink after a long time. The application forms a styrene-acrylic emulsion touch layer on the surface of the black card paper, which has good waterproofing and ink-proofing effects, and can better separate the ink and the black card paper, thereby avoiding the corrosion of the black card paper to the ink. The styrene-acrylic emulsion touch layer has the characteristics of lusterless, good wear resistance, excellent anti-sticking flower property, environmental protection, delicate touch and the like.

[0037]

[0038] It can be seen from the above that the black card paper anti-ink corrosion printing method and the black card paper product provided by the application form a styrene-acrylic emulsion touch layer on the surface of the black card paper, wherein the styrene-acrylic emulsion touch layer is prepared from the following components: styrene-acrylic emulsion, water-based resin, additives and water. Thus, the coating layer formed after curing has the effects of waterproofing and ink resistance, the coating film of the water-based resin after curing has the effect of corrosion resistance, and excellent corrosion resistance is formed. The applicant found that the black card paper contains a large amount of black filler, which is mainly composed of carbon elements, and accounts for 60%-70% on the black card paper, so that the paper is strongly acidic, and the black card paper will corrode the surface ink after a long time. The application forms a styrene-acrylic emulsion touch layer on the surface of the black card paper, which has good waterproofing and ink resistance, and can better separate the ink and the black card paper, thereby avoiding the corrosion of the black card paper to the ink. The styrene-acrylic emulsion touch layer has the characteristics of matte, good wear resistance, excellent anti-stickiness, environmental protection, delicate touch and the like. Through comparative test results, a layer of treatment is made on the surface of the paper to form an obstacle between the ink and the black card paper, which has the effects of waterproofing and corrosion resistance, and the coating film of the touch oil after curing makes the surface of the paper more delicate and smooth. The touch oil contains styrene-acrylic emulsion and water-based resin, the styrene-acrylic emulsion has the effects of waterproofing and ink resistance, the coating film of the water-based resin after curing has the effect of corrosion resistance, and excellent corrosion resistance is formed. The applicant coats a layer of touch oil on the black card paper to solve the technical problem of ink deterioration on the black card paper, to ensure the quality of the printed matter, so that the ink printed on the black card paper can well ensure the effect of the ink essence. Thus, the black card paper after printing ink has the problems of discoloration, blackening, lightening and the like.

[0039] It should be noted that the existing black card paper printing technology has quality problems such as discoloration, blackening and lightening, so it is necessary to solve the black card paper printing quality problem while maintaining the original texture effect of the black card paper, and direct printing technology on the black card paper has become a new topic, and direct printing technology on the black card paper will become a development direction. Therefore, the applicant proposes a "black card paper anti-ink corrosion printing technology research and development" project to provide a process for preventing ink from being corroded, aiming to solve the technical problem of ink deterioration of the existing black card paper.

The touch oil contains styrene-acrylic emulsion and water-based resin, the styrene-acrylic emulsion has the effects of waterproofing and ink resistance, the coating film of the water-based resin after curing has the effect of corrosion resistance, and excellent corrosion resistance is formed.

[0040] Black card paper is a kind of main circulation packaging material in modern society, and the main process on the surface of black card paper on the market is mainly UV and gold stamping. In the existing technology, printing on black card paper is to print a layer of white ink first and then print graphics on the white ink.

This problem is a big problem in the industry. In order to avoid such problems, we coat a layer of touch oil on the black card paper to solve the technical problem of ink deterioration on the black card paper, so as to ensure the quality of the printed matter, so that the ink printed on the black card paper can well ensure the effect of the ink essence.
