BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded view of an interior pattern resistant board manufactured in accordance with an embodiment of the present invention. FIG.
The present invention relates to a manufacturing method of a fire retardant board which directly prints an interior pattern using a water-based ink, unlike a method in which a toxic gas and a carcinogen are not generated in a fire and a conventional surface material is attached to a conventional fire- The present invention relates to an interior pattern non-burned board manufactured according to the above-described method.
Hereinafter, the present invention will be described in detail.
A method for manufacturing an anti-burning board in which a water-based ink of the present invention directly prints an interior pattern comprises the steps of: (A) removing foreign matters on the upper and lower surfaces of the non- (B) applying a primer composition having a viscosity of 3,000 to 5,000 cps on one surface of the non-burnable board from which the foreign substance is removed to form a primer layer; (C) applying a water-based ink composition comprising an aqueous urethane resin, an aqueous acrylic resin, a vinyl acetate resin, an inorganic pigment and a miscible adjuvant on the primer layer to form a print layer; And (D) drying the flame-retardant board on which the print layer is formed in five steps at different drying temperatures.
First, in step (A), the upper and lower surfaces of the non-burnable board are removed.
A brushing process and an air cutting process are simultaneously performed to remove all the foreign materials adhering to the fireproof board, and specifically, 1) air-cutting the fireproof board; 2) treating the air-cut non-burned board with a brush rotating in a forward direction; And 3) processing the brush with the brush rotating in the forward direction and rotating the brush in the reverse direction, and operating the dust collector while cutting the air. Unlike the above-mentioned method, when only air-cutting is performed or only brushing is performed, dust as well as foreign matter is not removed. In the case where the brush and air-cutting are not simultaneously performed in the step 3) May not be removed. Therefore, it is necessary to carry out the method of 1) to 3) as described above to completely remove foreign matter and dust.
The air-cutting is a method of discharging strong wind on the upper and lower surfaces of the fire-retardant board. More specifically, a strong breeze of 25 to 30 mph, 40 to 50 km / h , 10 to 20 m / s, and 20 to 30 knots are discharged through an air knife having a length of 1 to 2 m and a nozzle gap of 1 to 3 mm.
The bristles are used to treat upper and lower surfaces of a fire-retardant board in a manner of sweeping. Specifically, the bristles are made of radiation crosslinked polyethylene or nylon to have a thickness of 0.2 to 1.0 mm and a length of 10 to 50 mm, .
The non-burnable board may be a board, a cement fiber or an ocher board containing at least one selected from the group consisting of gypsum, calcium silicate, calcium carbonate, calcium silicate, volcanic ash, aluminum and magnesium.
Next, in the step (B), a primer layer is formed by applying a primer composition having a viscosity of 3,000 to 5,000 cps on one surface of the fire-retardant board from which the foreign substance has been removed, and drying at 50 to 200 ° C.
The primer layer is a layer that reduces the water absorption of the non-burnable board and improves the adhesion of the non-burnable board and the print layer, as well as improves the color development of the print layer. The aqueous primer composition is applied by a brush, a silk screen, a roller, . The primer composition does not need to be uniformly applied to a fire retardant board with high precision, and even if it is non-uniform, it acts as a primer when applied to a small amount of fire retardant board surface.
The primer composition may contain 0.1 to 10 parts by weight, preferably 1 to 5 parts by weight, of an aqueous ethylene vinyl acetate resin per 100 parts by weight of at least one resin composition selected from the group consisting of an aqueous urethane resin, an aqueous acrylic resin and a vinyl acetate resin ; And 30 to 80 parts by weight of water. The viscosity of the thus prepared primer composition is 3,000 to 5,000 cps, preferably 3,000 to 3,500 cps.
When the viscosity of the primer composition is less than the lower limit, the adhesion between the flame retardant board and the print layer may deteriorate and the color development degree of the print layer may not be improved. If the viscosity exceeds the upper limit, The frying layer and the print layer can be peeled off.
Accordingly, the primer composition should have a low viscosity as described above for excellent water absorbability and color development. Since such a low viscosity primer composition has poor adhesion to a fire retardant board, It is preferable to use a vinyl acetate resin.
When the content of the aqueous ethylene vinyl acetate resin in the resin composition is less than the above lower limit, the adhesiveness with the flame-retardant board is lowered so that the resin can be easily dropped even at a small pressure, and if it exceeds the upper limit, the viscosity can be increased.
When the resin composition contains at least one of water-based urethane resin, water-based acrylic resin and vinyl acetate resin, they must be mixed at the same weight ratio to obtain a primer composition having desired properties.
Examples of the aqueous urethane-based resin include an ionomer-type polyurethane resin.
The aqueous acrylic resin may include at least one selected from the group consisting of butyl acrylate, ethyl acrylate, and hydroxyethyl acrylate.
Examples of the vinyl acetate-based resin include ethylene vinylacetate (EVA) emulsion or vinyl acetate-acrylic emulsion.
When the thickness of the primer layer is less than the lower limit, the primer layer may fail to reduce the absorbency of the flame-retardant board. If the thickness of the primer layer is higher than the upper limit, the primer layer may be formed to a thickness of 10 to 30 μm, preferably 15 to 20 μm. The adhesion to the printing layer may be lowered and the coloring degree may be lowered.
Next, in step (C), an aqueous ink composition is applied on the primer layer formed in step (B) to form a print layer.
Aqueous ink composition
The print layer is formed by coating with a silk screen or a digital printing method as a layer for forming a desired pattern.
The ink composition comprises 30 to 70 parts by weight of an inorganic pigment, 3 to 10 parts by weight of a miscible adjuvant and 30 to 80 parts by weight of water based on 100 parts by weight of a mixed resin composed of an aqueous urethane resin, an aqueous acrylic resin and a vinyl acetate resin .
The mixed resin is prepared by mixing a water-based urethane resin, an aqueous acrylic resin, and a vinyl acetate resin in a weight ratio of 1: 1: 1 so that the viscosity is 10,000 to 40,000 cps so that the ink composition is strongly adhered to the primer layer So that the printed layer is formed directly on the non-burned board without any additional process. The types of the aqueous urethane resin, the aqueous acrylic resin and the vinyl acetate resin are the same as those of the aqueous urethane resin, the aqueous acrylic resin and the vinyl acetate resin used in the primer composition.
The inorganic pigment is a substance that imparts color to the print layer; Bauxite powder, calcium carbonate, acrylic resin or EVA resin, silica, titanium oxide, propylene glycol, and silane.
If the content of the inorganic pigment is less than the lower limit value, a desired color may not be exhibited. If the content exceeds the upper limit value, the print layer may peel off with time.
Also, the miscibility auxiliary agent is a substance used for easily mixing the mixed resin and the inorganic pigment with water, and it is preferable to use one or more kinds selected from the group consisting of a polyoxyethylene compound, a polyoxypropylene compound and a polyoxyethylene-propylene compound .
When the content of the miscible adjuvant is less than the lower limit, miscibility may be deteriorated. If the content exceeds the upper limit, leveling may be lowered and the coating may not be smoothly applied.
Auxiliary ink composition
The auxiliary ink composition improves the coloring degree of the ink composition, delays drying and improves the workability, further improves the adhesion with the primer layer, and also assures self-leveling and smooth printing layer formation .
The aqueous ink composition and the auxiliary ink composition are mixed at a weight ratio of 1: 0.8-1.2, preferably 1: 1-1.2. When the content of the auxiliary ink composition is lower than the lower limit based on the aqueous ink composition, The workability and adhesiveness may be deteriorated. If the upper limit is exceeded, the print layer may be formed unevenly and unevenly.
The auxiliary ink composition comprises 50 to 80 parts by weight, preferably 50 to 60 parts by weight, of butyl acrylate per 100 parts by weight of polymethylmethacrylate; 50 to 90 parts by weight, preferably 60 to 80 parts by weight of 2-ethylhexyl acrylate; 10 to 40 parts by weight, preferably 15 to 25 parts by weight, and 40 to 90 parts by weight of diethanol amine having a vaporization point of 200 to 270 ° C.
The above polymethyl methacrylate, butyl acrylate and 2-ethylhexyl acrylate are used together to increase the color of the ink composition and improve the adhesion with the primer layer. In addition, it can be used together with a mixed resin of an aqueous ink composition and diethanolamine to excellently perform self-leveling.
When the content of butyl acrylate and 2-ethylhexyl acrylate is less than the lower limit value based on the polymethyl methacrylate, the color developing degree of the print layer is not improved and the adhesiveness may be deteriorated. When the content is higher than the upper limit value The printing layer may not be flat, may be formed unevenly, and the releasability may be deteriorated.
remind By using the diethanolamine having a vaporization point of 200 to 270 DEG C, mass production is possible by delaying the drying of the ink composition. If diethanolamine having a vaporization point of 140 to 180 DEG C is used instead of 200 to 270 DEG C, the ink composition is rapidly dried, and if dried for 2 minutes, it can not be mass-produced, workability is poor, Lt; / RTI >
The thickness of such a printing layer is 10 to 100 mu m, preferably 20 to 50 mu m. When the thickness of the print layer is less than the lower limit value, the desired coloring degree can not be exhibited, and when the thickness exceeds the upper limit value, gloss can be lowered.
Next, in the step (D), the non-burned board on which the printing layer is formed is dried and cured in five steps at different drying temperatures.
The printing layer is not easily dried and bubbles are easily generated in the drying process, so that the bubbles are not formed by sequentially drying in five zones having different temperatures.
Specifically, the non-burned board on which the print layer is formed is dried at 30 to 50 ° C in one step to cure the interior of the print layer and dried in two steps at 70 to 80 ° C to further dry the inside of the print layer, The printed layer is dried at 100 to 150 ° C to dry the outside of the printed layer to initially cure the printed layer and dried at 70 to 80 ° C in four steps to harden the printed layer, Lt; RTI ID = 0.0 > 15 C < / RTI > to harden the print layer more tightly. In the step 5, when the cooled air is directly discharged, cracks may occur in the printing layer, and therefore, it is preferable that the drying is performed at 30 to 50 ° C.
In each of the drying steps, drying is performed for 1 to 10 minutes.
Next, in the step (E), a UV curable resin or a transparent resin is coated on the non-burnable board on which the print layer is formed to form a coating layer.
The coating layer is formed by coating a UV curable resin or a transparent resin with a curtain coat, a comma coat, a reverse coat, a gravure, a flexographic printing method or the like in order to prevent contamination of the print layer and to control wear resistance and gloss .
The UV curable resin is prepared by mixing 50 to 80 parts by weight of an unsaturated polyester acrylate oligomer and 1 to 10 parts by weight of a polyurethane resin with respect to 100 parts by weight of the urethane acrylate oligomer to prevent the cured UV resin from breaking.
The UV curable resin is cured with at least one lamp selected from the group consisting of a mercury lamp, a metal halide lamp, and a potassium lamp.
The transparent resin is not particularly limited as long as it is a resin forming a transparent coating layer.
Next, the step (F) is a step of applying a polyethylene film having a thickness of 50 to 100 탆 on the non-burnable board on which the print layer is formed, or on the non-burnable board having the coating layer formed in the step (E) And then the protective film layer is formed by adhering it using a pressing rubber roller.
The present invention also provides an incombustible board directly printed with an aqueous ink, which will be described with reference to Fig.
The interior pattern non-burnable board, in which the water-based ink of the present invention is directly printed, is manufactured according to the above-described manufacturing method and comprises a

As shown in Table 1 above, it was confirmed that the fire-retardant board directly printed with the water-based ink prepared according to Examples 1 and 2 of the present invention was excellent in both adhesion, surface hardness, water resistance, smoothness and abrasion resistance, .
On the other hand, Comparative Examples 1 to 6 were found to show poor results in all tests. Although the test result of Comparative Example 4 is excellent in Comparative Example 1-6, there is a problem that the aqueous ink composition hardens within 2 minutes and is difficult to use.
Test Example 2.
The following tests were carried out on the non-burned boards produced in the above Examples and Comparative Examples.
2-1. Formaldehyde emission (mg / L): It was confirmed by KS F 3217 test method (standard value: 5 or less).
2-2. VOC Resistance: confirmed by JIS A 1901 test method.
2-3. Permeability: Determined by KS F 4936 test method (standard value: not to be watered).
2-4. Water vapor permeability (g / m 2 24h): It was confirmed by KS F 4936 test method (standard value: 50.0 or less).
2-5. Impact resistance: confirmed by KS D 6711 test method (standard value: no abnormality).
2-6. Nonflammability: confirmed by KS M 3015-95 test method.
As shown in Table 2 above, the fire-retardant board directly printed with the water-based ink produced according to Examples 1 and 2 of the present invention did not release heavy metals and toxic substances, and compared with Comparative Examples 1 to 3 and Comparative Examples 4 to 5 It was confirmed that the water permeation resistance was excellent and that it was resistant to heat.
On the other hand, Comparative Example 4 has a problem that it is difficult to use because the water-based ink composition hardens within 2 minutes when the incompatibility is excellent.
