Description

About formation plotter output fabric high efficient one coating system}

The present invention can be expected to significantly reduce the material cost and coating process (time) by fully exhibiting properties such as excellent adhesion, durability, color development, chemical resistance, etc. required for printing with only a smaller amount of coating agent and a single coating process. The present invention relates to a raw coating agent for a large plotter output fabric (advertising fabric, such as due diligence and banners) and a method of manufacturing the same.

Usually, since the fabric has four layers, the smoothness and durability are inferior, and the spreading property is required. Therefore, it is essential to perform a coating process of coating (or coating) the coating on the surface before printing.

The coated large-format plotter can be printed with various means such as digital printing machines, digital inkjet plotters, printers, printers, and various patterns such as letters, symbols, numbers, images, and photographs. Because it's used for promotion and advertising,

In the coating process for large-format plotter printing, the ink absorption and adhesion should be good, and there should be no ink bleeding or curling, and after printing, the drying speed should be fast, especially the color clarity must be very good. Durability also requires excellent functional coatings.

Conventional coating agent for satisfying this to form a primary coating layer of a certain thickness through the first base coating process in order to give the adhesion and basic properties on the fabric surface for the live-action and banner printing,

In order to form the secondary coating layer through the secondary top coating to give the color development, durability, chemical resistance, etc. required for printing on the primary coating layer,

In addition to the primary and secondary coatings individually manufactured, each of the first and second coatings should be applied by a two-step coating method, which inevitably consumes considerable time and material cost during the first and second coating processes. therefore,

When coating the large plotter output fabric, there is a problem that a considerable material cost and process (time) was wasteful, which requires a lot of manufacturing cost, and such a problem is urgently improved, leading to a weakening of the company's price competitiveness.

In other words, the primary coating solution (adhesiveness and basic properties) and the secondary coating solution (color development and durability, chemical resistance, etc.) are mainly manufactured for the composition that is the key to give the necessary functions for each step in the manufacturing, It is inevitable to consume more than one original coating due to the application thickness and coating amount that is basically followed when applying the 1st and 2nd stage coatings, and the loss rate of the coating agent following each stage of coating application. In addition, the same factors such as the double manufacturing time, cost involved in the individual production of the primary coating will also be accompanied.

 Therefore, the present invention was devised to solve the above-mentioned problems. Unlike the conventional coating agent, which required a considerable amount of materials (primary and secondary coating agents) and many coating processes of two or more steps, it is required to print only one raw coating process. It is completed as a technical problem with the focus on providing a high efficiency coating and a method of manufacturing the same to satisfy all the properties to reduce the enormous material, process (time) and manufacturing cost.

The present invention for achieving the above technical problem is silica, hydrophilic resin (urethane resin, acrylic resin, polyvinyl alcohol resin, polyvinylacetate resin, EVA resin or more selected one) and liquid paraffin, fatty acids, surfactants, salt pigments Anti-bleeding, antistatic and anti-bleaching agents are mixed with solvents (at least one organic alcohol selected from methanol, ethanol and isopropyl alcohol) and water. The high-efficiency original coating agent and its manufacturing method meeting the required physical properties are the characteristics.

As described in detail above, the coating agent of the present invention provides adhesiveness and basic physical properties in primary base coating, which is a fabric manufacturing method for real-life and banner printing when coating on large-format plotter-output fabrics such as live-action and banner film, and second top coating Unlike conventional unreasonable coatings, which had to go through two or more knife coating processes to give final properties (color development, durability, chemical resistance, etc.), only one small coating process and coating amount completely meet the requirements of printing. Using the output digital printing machine can process more production at a lower cost and process when coating the advertising materials such as due diligence and banners, it can greatly contribute to cost reduction and productivity increase, and particularly provided by the present invention. High-efficiency coating agent can be printed on the inside and outside , Banners, bar whose expectations water resistance, durability and alkali resistance, color distortion or discoloration resistant to acid addition does not happen at all when used as a signage such as an invention of the room.

Looking in more detail with respect to the action of the components shown in Examples 1, 2, 3,

    ① Silica absorbs aqueous pigment ink or oily pigment ink to prevent bleeding and promote color development.

 ② Polyurethane resins and polyacrylic resins generally use resins in which the molar ratio of hydrophilic monomers is less than 20% for polyurethane resins and less than 10% for polyacrylic resins. These resins prevent dye transfer of ink deposited inside fabric after printing. It also serves to improve various fastnesses (water resistance, chemical resistance, durability, etc.) and at the same time plays a role of improving color appearance.

 ③ The surfactant can be used both nonionic surfactants, anionic surfactants and cationic surfactants having a HLB (friendship-lipophilic balance) value of 1-10, and fatty acids include fatty acids having 10 or more carbon atoms or Fatty acid ethers or fatty acid ester compounds may be used and may be used alone or as a mixture thereof and mixed emulsions with liquid paraffin. They assist in the uniform settling and penetration of the ink into the fiber during printing and also serve to greatly enhance the color development of the seated dyes and inks.

④ Liquid paraffin and fatty acids provide waterproofing function and protect pigment pigments of water-based ink or oil-based pigment ink from water or rain.

⑤ Polyvinyl alcohol resin, polyvinylacetate resin, EVA resin, water, etc., improves the coating property by controlling the permeability of the coating agent, and also plays a role of further improving durability by serving as an adhesion assistant.

⑥ As the dye pigment anti-bleeding agent, a conventional anti-bleeding agent which is used when printing non-ionic and cationic mixtures can be used, which helps to prevent bleeding of ink and dyes during printing, and various colors and patterns are clearly printed on the fabric. Play a role.

7. Antistatic agents include polyalkylene glycol-based nonionic surfactant mixtures, guanidine hydrochloric acid-based cationic and inorganic salt mixtures, alkyl phosphate-based anionic surfactants, quaternary ammonium compounds and derivatives thereof, and polyester oligomer resins. Antistatic agents for textile processing such as systems can be used, and it plays a role of preventing the scattering and bleeding of dyes and inks due to static electricity during digital printing.

⑧ Representative examples of salt and pigment decolorization inhibitors include UV blockers, and nonionic, cationic and anionic compounds may also be used. This protects the ink and dye surfaces from the effects of light after digital printing to prevent decolorization.

⑨ Solvent plays an important role in obtaining the desired product quality after coating by improving the coating property by improving the flowability of chemicals during coating, improving the permeability of chemicals, and improving the dryness in the drying chamber. The proper organic solvent should be selected and mixed according to the requirements.

As described above, the coating agent of the present invention can be prepared, as described above, without requiring a large number of coating processes (two or more coatings), and only one coating is required, and the significant adhesiveness required for outputs such as actual prints or banners. It is a useful invention that provides a high efficiency coating that can be endowed with durability, color development, durability, bleeding prevention, discoloration prevention, waterproofing, chemical resistance and the like.

In addition, the fabric for yarn and banner printing of the present invention is not subjected to pre-treatment, dyeing, sizing fabric woven with blended yarns as well as synthetic fibers such as polyester and natural fibers such as cotton. It is applicable to both raw and pretreated and dyed processed paper.

Meanwhile, the coating agent of the present invention is coated with a thickness of 0.5 to 3.5 mm using a conventional coating knife as a slime state, and then dried at a speed of 30-60 m / min in a hot air chamber having a drying temperature of 130 ° C. to 170 ° C. At this time, the angle of the knife is preferably set to 60 ° ~ 90 °.

In addition, the component ratio of the coating agent of the present invention described above may be appropriately changed according to the use of due diligence, banners, etc., or the demand quality of the consumer according to one embodiment.

Although the original coating agent of the present invention has not only added about 60-85% of the coating agent as compared to the conventional two-step coating as described above, but also formed a coating layer by only one round coating process,

When printing, it can be seen that the ink is firmly and perfectly seated. Especially, it is resistant to water resistance, durability, alkali resistance, and acid resistance, so that high-quality prints of front color can be obtained without any color change.

As a result, not only the significant reduction in coating process and production cost could be expected, but also the enormous amount of material input and environmental pollution due to the reduction of coating amount.

Furthermore, even if the separate waterproof coating is omitted when the coated yarn is posted outdoors, it is possible to completely prevent the spread of ink due to rainfall or snowfall, the dropping of the coating layer, the discoloration, and the discoloration. It can last for a long time.

Furthermore, when the coating agent is required for a flame retardant function, the flame retardant coating agent may be prepared by mixing 50 to 95% by weight of the coating agent at a ratio of 5 to 50% by weight of the flame retardant.
