Abstract
The present invention relates to an enamel blackboard and a manufacturing method thereof, in which a printing unit is printed by silk-screen printing. More specifically, the present invention relates to a method of manufacturing an enamel blackboard having a printing unit including characters, patterns, and pictures necessary for a learning program It is characterized by being able to maximize the learning effect by directing the silk screen printing by the enamel glaze to produce the beautiful or printing the contents necessary for the learning.
Description
The present invention relates to a method and apparatus for producing an embossed blackboard, in which a printing unit including characters, patterns, and figures necessary for a learning program is silk-screen printed and integrated to produce a visual beauty and maximize a learning effect, The present invention relates to a printed enamel blackboard and a manufacturing method thereof.
In the past, chalkboard was mainly made of chalk, but in recent years, a white board painted with white paint on the upper surface of wood or plastic plate is used.
Unlike the chalkboard that uses chalk, the whiteboard uses a marking pen, so it is easy to use because there is no inconvenience that the chalk powder is blown away or the chalk powder adhered to the board eraser is shaken off.
However, in such a conventional whiteboard, over time, the paint coated on the top surface is discolored by ultraviolet rays, and the whiteness of the blackboard gradually decreases.
Therefore, not only the written characters on the whiteboard are not clearly visible but also the appearance is not good, and the surface hardness is low, so that scratches easily occur.
In addition, since the whiteboard is frequently used, the whiteboard surface becomes black due to long use of macapens, which makes it impossible to use for a long period of time, resulting in ineffective results.
Therefore, recently, enamel blackboard which is harmless to human body and excellent in durability is used.
The enamel chalkboard has a structure in which an enamel glaze is applied to the surface of the steel sheet and then fired in a firing furnace to form an enamel layer on the surface thereof.
However, the conventional enamel chalkboard is formed by applying enamel glaze and then firing the surface to form an enamel layer. Since the surface of the enamel layer is simple and beautiful, the quality of the enamel is lowered. The learning effect is deteriorated.
In addition, characters, patterns and the like are not printed on the enamel layer surface of the enamel chalkboard, so that there is a problem that the infant or child is visually curious and does not attract interest.
In order to solve the above-mentioned problems, it is an object of the present invention to provide a printing unit by forming silk screen printing on an enamel layer formed on the surface of an enamel chalkboard including various characters, patterns, pictures, etc.
In order to solve the above problems, the present invention provides an enamel chalkboard on which a silk screen printing section with characters, patterns, and pictures is printed on the surface of the enamel layer.
In addition, the present invention relates to a method for producing an enamel layer, which comprises silk screen printing using enamel glaze mixed with pigment to express characters, patterns, and pictures on the surface of the enamel layer, firing in a firing furnace, A silk screen printed with the mixed enamel glaze, followed by firing in a firing furnace, followed by repeating the drying process to silk screen printing to a color of 5 degrees.
As described above, according to the present invention, the enamel chalkboard has a printed portion made of enamel glaze on the surface of the enamel layer by silk screen printing of letters, patterns, and pictures, thereby providing a beautiful enamel layer, And can be used continuously to increase the learning effect.

2 is a flowchart showing a method of manufacturing an enamel chalkboard according to the present invention.
In order to achieve the above objects and effects, the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a perspective view showing an enamel chalkboard according to an embodiment of the present invention, and FIG. 2 is a flowchart showing a method of manufacturing an enamel chalkboard according to the present invention.
In the present invention, the enamel chalkboard 1 is formed integrally with the
It is preferable that the printing section 3 is formed by silk screen printing a part of the surface of the
In order to manufacture the enamel chalkboard 1, a steel sheet is first cut to a standard size, and then an enamel glaze is applied to the surface, followed by drying and baking at a temperature of 740 to 840 ° C in a baking furnace to form an
In order to form the printing section 3 silk-screen printed on the enamel layer 1 of the enamel chalkboard 1, the printing section 3 including characters, patterns, and pictures is silk-screen printed using an enamel glaze, And then baked at a temperature of 600 to 750 ° C. for 10 to 15 minutes in a firing furnace to form the printing unit 3 as a single unit.
Then, on the surface of the enamel layer (2) of the enamel chalkboard (1), the printing section (3) including letters, patterns and pictures is silk screen printed and can be visually beautiful.
In addition, the printing unit 3 can be produced in various colors by silk screen printing in a color of 1 degree to 5 degrees.
In order to perform silk screen printing in a color of 1 to 5 degrees, the printing unit 3 selects five enamel glazes mixed with pigments and sequentially uses a part of the printing unit 3 as a first color in a silk screen After printing and drying, the mixture is fired in a firing furnace at a temperature of 600 to 750 ° C. for 10 to 15 minutes, cooled, and then silk-screen printed in a second color on the printing section (3) It is baked at a temperature of 600 ~ 750 ℃ in a firing furnace for 10 ~ 15 minutes.
In this manner, the third to fifth colors are repeated and the enamel glaze is used in order to complete the printing unit 3 by silk screen printing.
On the other hand, the printing unit 3 can select a color of 1 to 5 degrees and print it according to the operator's selection.
