Description
The present invention relates to a board capable of writing such as a blackboard, and more particularly, to a board on which a ceramic coating layer is formed so that afterimages do not occur and reflection by light does not occur.
The writing board currently being developed and being used is coated with a color layer such as dark green, dark blue and dark brown on one surface of a main plate made of wood, vinyl and steel, or a colorless layer such as white.
In recent years, white boards have been used a lot for office work. White boards can usually be written with a board marker, and the written surface can be erased with a dry eraser.
Such a white board was able to maintain the neatness by solving the problem that dust, such as chalk powder occurs when the writing using a conventional chalk.
However, when the white board is erased after writing, afterimages of the board markers remain, and the afterimage of the board markers can be completely erased only by using a separate cleaner.
In addition, the conventional white board has a difficulty in identifying the written contents due to surface reflection when exposed to fluorescent lights or sunlight, and is not suitable for use as a screen for beam projects.
SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object of the present invention is to provide a board on which a ceramic coating layer is formed so that afterimages are not left after writing and surface reflection is not generated by light.
In order to achieve the above object, according to an embodiment of the present invention, there is provided a board including a main plate and a ceramic coating layer formed on the upper surface of the main plate, the ceramic coating layer is nano-silica (Nano-Silica) 10.0-35.0 wt% Modified Polysiloxane 10.0-30.0 wt%, Nano-Ceramic polymer 15.0-25.0 wt%, Isopropyl Alcohol 5.0-10.0 wt% and Methylethylketone ( Methylethylketone) is formed by coating a ceramic coating paint containing 5.0 to 10.0% by weight.
According to an embodiment of the present invention, the ceramic coating paint may further include a material having a color.
In addition, according to another embodiment of the present invention, a color coating layer formed by the application of a material having a color between the main plate and the ceramic coating layer is provided, a transparent ceramic coating layer may be applied to the upper surface of the color coating layer. .
Board manufacturing method with a ceramic coating layer according to the present invention is nano silica (Nano-Silica) 10.0 ~ 35.0% by weight, modified polysiloxane (Modified Polysiloxane) 10.0 ~ 30.0% by weight, nano ceramic polymer (Nano-Ceramic polymer) 15.0 ~ 25.0 %, Preparing a ceramic coating paint comprising 5.0 to 10.0% by weight of isopropyl alcohol and 5.0 to 10.0% by weight of methyl ethyl ketone and coating the ceramic coating on the upper surface of the main plate It may be made, including.
Here, the ceramic polymer constituting the ceramic coating paint is preferably after adding nano silica and organosilane in a mixed solution of isopropyl alcohol, methyl ethyl ketone and water It is synthesized by the sol-gel process and has a nano-sized particle form.
According to an embodiment of the present invention, the ceramic coating paint may further include a material having a color.
In addition, according to another embodiment of the present invention, the step of coating the ceramic coating paint to form a color coating layer by applying a material having a color on the upper surface of the main plate, the ceramic coating paint on the color coating layer It may consist of coating.
First, since the coating layer formed on the upper surface of the main plate is made of ceramic coating paint, it has excellent durability, chemical resistance, heat resistance, etc., and when erasing a sheet written with a board marker, there is no afterimage left to maintain a clean surface. have.
In addition, the writing written in water chalk, which was difficult to use in the prior art, also has an advantage that can be erased without afterimages.
Second, since the coating layer is formed by the ceramic coating paint hardly causes surface reflection by light, it is easy to identify the written contents even in an environment exposed to light such as a fluorescent lamp or sunlight.
In addition, due to the matte effect of the surface can replace the screen for the beam project, there is an advantage that can be written while using the beam project.
