Abstract

Solid pattern board is manufactured from substrate material, such as asbestos sheet, glass fiber sheet or paper, by coating the paste sol with or without foaming agent. The paste sol is gelled in a heating chamber at 140-150≰C temp. and cooled to 100-120≰C or room temp. Ink contg. sublimate dye is printed onto the board surface and the product is obtained by heating the mixture to 210-240≰C and quenching it after coating the transparent paste sol layer on to te printed surface.

Description

Method of manufacturing three-dimensional pattern material

The present invention is based on asbestos paper, glass fiber paper, and paper (hereinafter referred to as substrate), and a opaque paste sol containing a foaming agent or a foaming agent on the substrate is coated with a constant thickness. Silk screen or gravure printing machine using oil-soluble and dispersible dyes with sublimation temperature of 170 ℃ or higher after gelation after uniform application, gelation by heating about 140-150 ℃ and cooling or complete cooling to 100-120 ℃ After printing or transferring the pattern with a transfer paper printed using the printing machine or by using a printing machine, the transparent sol is uniformly applied again, and then the dye is produced by passing through a foaming furnace heated to 200-250 ° C. to produce a transparent sol (upper layer). It is a method of manufacturing a flooring material that penetrates into a layer, has a clear, three-dimensional appearance, and has a pattern even when the exterior is worn.

Conventionally, a sol layer containing a blowing agent is applied to the above-mentioned base material, followed by gelation, followed by gelation of an ink containing a blowing inhibitor mixed with various colors of fuel, using a gravure or transfer paper to print a colorful pattern, and then applying a transparent sol layer again. The gel was completely gelled to produce a curative material with cursion and irregularities. However, the upper extremity was applied thinly to give an uneven effect. After printing a pattern by putting a crosslinking agent into the ink on the ingel layer and then crosslinking the UV and radiation irradiating device, a product is produced by gelizing by uniformly applying a sol on the surface to prevent abrasion due to abrasion. There were disadvantages that the investment cost and the product were expensive. Glue the adhesive or sol lightly with a Reknife coster, Reverse Roll Coster, or Comma Coater, and apply 4 or 8 square sheets of vinyl sheet or asbestos sheet with a thickness of about 1 m / m. Alternatively, the chips pulverized into amorphous small pieces are uniformly distributed and gelled or dried, and then coated with a powder or sol layer containing various stabilizers on the surface layer to be completely gelled, but it is disadvantageous due to the high cost and high product cost of the device. There is a point.

In the present invention, when using a dye having a sublimation temperature of 180 ° C. or higher, the dyeing depth can be changed by using only a special dyeing method. Was sublimed in advance and did not penetrate, and it was found that a predetermined effect could not be obtained.

Therefore, in the present invention, the sol layer is half-gelled at 140-150 ° C. before printing, and then cooled to 100-120 ° C., then transferred directly to a room temperature or printed directly, and then the cap sol layer is applied to the surface to adjust the foamer to 200-250 ° C. By passing through, the sol layer became a complete gel layer, and the dye vapor was sublimed into the vent from the solvent of the sol and the intermolecular relaxation.

Therefore, the sublimable dye used in the present invention should be maintained at a sublimation temperature of at least 180 ° C., preferably using a sublimable dye having a sublimation temperature of about 30-60 ° C. lower than 210-240 ° C. of the plastic sol. It is good.

The sublimable dye used in the present invention will be specifically illustrated by way of example: Stanred 7B, Servant Green 70013, Savinyl dye water 3GS.Fallanyl Yellow 5G, Leplin Brown FBL, Latiled GFS. (Hereinafter referred to as a sublimable dye), a transfer paper printed in the color of the pattern required by dyes having a sublimation temperature of 180 ° C. or higher, and directly printed on the gelled surface of the pastesol cooled by gravure or silk screen. If the surface temperature of the gel layer is cooled to 100-120 ℃ lower than the gelation temperature 140-150 ℃ during use, a clean surface can be obtained by volatilization of solvent and water volatilization of printing ink. When the temperature of the pressing roll is heated to 100-120 ° C., sufficient transfer is achieved by pressing, and thus there is no problem in achieving the object of the present invention.

The PVC paste sol used in the present invention is not affected by using a copolymer made of vinyl acetate, acrylonitrile and the like as well as pure PVC paste sol.

The printing method of the present invention can be printed by a commonly used printing method such as printing, screen printing or gravure printing. Mix them together.

The paste sol is uniformly coated on the surface with asbestos, glass fiber and zoni as a coater, and gelled at 140-150 ℃ and cooled to 100-120 ℃ to use transfer paper or printed directly on the surface. By applying paste sol layer and passing through 210-240 ℃ hot blast furnace to commercialize it, sublimable dye sublimates and penetrates into sol so that color does not bleed sideways and the color becomes vivid and there is no pattern even in long-term use. Does not manufacture the material.

Hereinafter, the present invention will be described in detail as follows.

Example 1

Using a printing roll engraved with a figure to be printed, the ink mixed with the dispersible dye is uniformly coated with a paste sol on a substrate using a gravure printing machine, heated to 150-160 ° C., and printed on the semigelled surface. After the transparent sol layer was applied to the cotton, the resultant was cooled by passing through a heat box at 210-240 ° C. to obtain a three-dimensional pattern in which the color was clear and the dye penetrated to the transparent solvent.

Example 2

Printed on the transfer paper with the printing roll and transferred to the semi-gelled surface made in the same manner as in Example (1), and then applied a transparent sol layer and passed the heat of 210-240 ℃ to obtain the same results as in Example (1) there was.

Example 3

When the ink was printed by a silk printer and carried out in the same manner as in Example (1), the same result as in Example (1) was obtained.

Claims (1)

A paste sol with or without foaming agent is applied to the substrate, Asbestos paper, glass fiber and paper, and then gelled at 140-150 ° C. in a hot box or a hot tub, and then cooled to 100-120 ° C. or room temperature, and then mixed with a sublimable dye on the surface. Print directly on the transfer paper or print on the transfer paper, press transfer the transfer paper to the surface and print the pattern, then apply a transparent paste sol layer on the surface of the printing layer to pass through the heat of 210-240 ℃ to quench and beautiful and ink to the upper layer Method for producing a three-dimensional pattern material characterized in that the penetration.
