Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a painted heat-resistant base material, and its purpose is to easily and efficiently produce a heat-resistant base material with a beautiful multicolored pattern. The object of the present invention is to provide a method that can be manufactured efficiently and at low energy cost.

Conventionally, there are various methods for manufacturing painted heat-resistant pottery such as ceramics and tiles, one of which is so-called raw glaze overlaying. This method involves applying a mixture of glaze and resin to the surface of an unglazed, heat-resistant base material, and then directly printing on it, such as screen printing, or slide transfer printing. ] After applying step 1, the temperature is about 1000℃~13℃
This method involves firing at 50°C. According to this method,
Since the firing process only requires one melon, it is possible to economically produce a heat-resistant base material at a low manufacturing cost.

However, if a direct printing method such as screen printing is used as the first means of painting in this method, the raw glaze surface is easily damaged during painting, and it is difficult to form precise multicolored designs, making it particularly delicate and beautiful. It was unsuitable for forming multicolored designs. On the other hand, if the slide transfer printing method, in which the slide transfer material is swollen in water and the pattern layer is slid and adhered to the surface of the base material, is used as a means of displaying the image, it is possible to print the delicate and beautiful multicolored pattern. Although it is suitable for printing, most of the processes are manual and time-consuming, and the surface of the base material easily absorbs moisture, so it is difficult to transfer print the pattern layer as it is. However, it was necessary to provide a sufficient fake I1 fat layer on the glaze to provide water resistance, making it as complicated as 2.

The present inventors are concerned about the drawbacks of the conventional method as described above,
As a result of various research and experiments, we have completed the present invention. Accordingly, the present invention provides a transfer material in which a transfer layer consisting of a release layer, a pattern layer, and a contact agent layer is laminated on a viscous sheet, and a glaze and a hardening agent coated thereon.
1F, transfer the transferred rYa onto the heat-resistant base material by applying pressure from the base sheet side, then peel off the base sheet, and then bake the iIJ design. This is a method for producing a heat-resistant base material, which is characterized by sintering a circle.

Hereinafter, the method for producing the j1) sex base according to the present invention will be explained in detail.

First, the transfer layer used in the present invention will be explained.

The transfer material 1 used in the present invention is a basic type of material in which a transfer layer 6 consisting of a peeling layer 3, a pattern layer 4, an adhesive layer 5, etc. is laminated on a W-body sheet 2 (No. (See Figure 1).

The base sheet 2 is used as a normal transfer layer.
It is possible to use paper such as double-quality paper, yaw 1-paper, 2571-paper, etc., or films such as polyethylene terephthalate, polypropylene, nylon, etc.

The peeling layer 3 of this base sheet 1-2-1 is formed using a hot melting wax or a synthetic resin that is releasable from the base sheet 2. These materials must have a fast extrusion rate and must be completely burnt out without leaving any residue during the firing process. For example, what is the method of forming (silk screen method, roll coat method)? It is preferable to use methods such as JG, barcode method, Reharsco-1 method, Tarahiako I-method, and the like.

The pattern layer 4 is formed using ordinary ceramic printing ink. Examples of the forming method include an offset printing method, a screen printing method, and a Clavier printing method. It would be better to use a combination of these printing methods, but ordinary ceramics'! 41 Depth pigment is a mixture of colored pigment and frit powder, so the color density,
In order to provide hiding power, screen printing method I■b is also suitable. In addition, the Clavier printing method, offset printing method,
When the pattern layer is formed using a method such as Ill, it is difficult to mix the frit powder into the ink, so it is better to overcoat the frit component using a spray method or a small sprinkling method after applying the transfer image. .

The adhesive layer 5 on the pattern layer 4 is preferably one that has the highest firing rate next to the release layer 3 and the pattern layer 4, and has the above-mentioned release If; As for the formation method, it is preferable to use the same method as that for the peeling layer 3 described above.

Next, the painted culm according to the present invention will be explained.

Place it so that it is in contact with the 7th surface. Gononu・
- Apply a glaze and a solidifying agent to the surface of the heat-resistant base material beforehand. The flll agent used is one that is normally used for ceramics, and the solidifying agent is ``for example, starch, cellulose, acrylic, or vinyl BI IIi? Alternatively, a mixture of these with polyoxyethylene oxai 1ζ, carakeenan, guar gum, etc. is used.

The glaze and solidifying agent may be applied by mixing the two in advance, or by first applying the glaze and then applying the solidifying agent. Heat resistant, )+(+g seed lamps 1 include ceramics, enamel, etc.

Next, the transfer material 1 is heated and pressed from the base sheet 2 side using an elastic body 8 such as silicon to transfer the transfer rΣ) layer 6 of the transfer material 1 to the pJ (resistant base material 7 surface). At this time, Preheating the heat-resistant substrate immediately before transfer improves rolling properties and increases transfer speed.

Next, the base sheet 2 is peeled off and then fired. Firing is about 1
Preferably, the temperature is between 000'C and 1350C. Through this firing, the design is sintered together with the glaze, creating a good picture.

In addition, in the present invention, it is possible to use a sheet of transfer material as a transfer material, and to place each sheet one by one on an unglazed surface and then heat and press it. Using a transfer material in the form of a handle, it is possible to continuously apply pressure with a roll-shaped elastic body, for example, a silicon roll. By doing the following, it is possible to achieve extremely high productivity.

<Example 1> A 25/J thick polyconidylene terephthalate film was bound to the base sheet I, and this film was peeled off using the grapier printing method using an ink consisting of the following composition (2). -"Secondly, a pattern layer is formed by a continuous screen printing method using an ink having the composition shown in (1) below, and an adhesive layer is formed on top of this by a crapier printing method using an ink having the composition (2) below. A transfer material was obtained.
