본 발명은 마커펜(marker pen) 사용이 가능한 U,V코팅 칠판의 제조방법에 관한 것으로, 더욱 상세하게는 일반 백묵칠판과 같은 바탕색을 갖되 공해 및 질병유발의 원인이 되는 백묵을 사용하지 않고 백묵색깔의 마커펜, 다시말해 수성펜등을 백묵대신 사용할 수 있게 함으로써 백묵사용에 따른 제반불편을 해소할수 있도록 함은 물론 운필성과 지움성을 향상시킨 칠판제조 방법에 관한 것이다.The present invention relates to a method for manufacturing a U, V-coated blackboard that can be used as a marker pen, and more particularly, has a background color like that of a general chalk board, but does not use chalk to cause pollution and disease. By using colored marker pens, that is, water-based pens, instead of chalk, it is possible to solve all the inconveniences caused by the use of chalk, as well as to improve the pencilability and eraseability.

일반적으로 대다수 교습용 칠판의 경우 시각적으로 피감을 덜주고 안정감을 주는 녹색을 바탕색으로 한 칠판을 사용하고 있는 것으로, 이경우 필기구로서 백묵을 사용하는 것이 교습용 칠판사용의 기본인 것이다.In general, most teaching blackboards use a green-based blackboard that gives visually less relief and stability. In this case, using chalk as a writing instrument is the basis of the teaching blackboard.

그러나, 상기와 같이 백묵을 사용하는 칠판은 시각적으로 피로감을 덜주고 안정감을 주는 측면, 다시말해 피교습자의 눈을 보호하는 측면에서는 사용상 별 무리가 없지만, 그 칠판과 아울러 사용되는 필기구는 반드시 백묵이어야만 하므로 이미 주지하고 있듯이 백묵을 사용하는데 따른 제반불편, 즉 필기시 및 필기된 내용을 지우개로 지우는 과정에서 백묵가루가 날리게 되어 백묵을 사용하는 강사는 물론이고 같은 강의실내의 피교습자들 까지도 백묵가루에 의한 공해를 피할 수 없게되어 건강을 해치게되는 문제점이 있으며, 또한 칠판에 적힌 내용을 지운 지우개의 처리에 있어서도 지우개를 털이개로 털어야 하는데 따라 미세한 백묵가루들이 공기를 오염시킴으로써 환경문제에도 크게 역행하게 되는 등의 심각한 문제를 유발하는 것이었다.However, the blackboard using chalk as described above has no problem in terms of visual fatigue and stability, that is, in terms of protecting the eyes of the subjects, but writing instruments used with the blackboard must be chalk. Therefore, as it is well known, chalk powder is blown in the process of using chalk, that is, when writing and erasing the written contents with an eraser, so not only the instructor who uses chalk but also the students in the same classroom. There is a problem that the pollution caused by the inevitable damage to health, and also to erase the contents written on the blackboard to erase the hair with an eraser, as the fine chalk powder contaminates the air, thereby greatly reversing the environmental problems It was causing serious problems.

또한 근자에 들어서 상기와 같이 백묵을 사용하는데 따라 야기되는 제반문제점으로 부터 탈피하고자 공해발생이 적은 수성펜이나 마커펜을 사용할수 있도록 한 하얀칠판(white board)이나, 세락믹 칠판이 안출, 사용되고 있는 실정이나, 이것은 백묵을 사용하지 않고 마커펜을 사용하므로 백묵가루에 따른 공해유발의 문제가 없을지는 모르나 칠판의 바탕색이 흰색이므로 시각적으로 안정감을 주지못해 피교습자들의 눈이 쉬 피로해질 우려가 있어 그만큼 학습능률을 저해하게 되어 효율적인 학습을 이룰수 없게 되는 문제가 발생되었으며, 세락믹 칠판의 경우에는 칠판면이 세락믹으로 되어 있기 때문에 마커펜 사용할 때 내약품성이 약하여 운필성과 지움성이 떨어져 칠판사용이 매우 어려운 상태로 되어 다시 새로운 제품으로 교환을 해야하는 문제가 발생되었다.In addition, in order to escape from the problems caused by using chalk as mentioned above, a white board or a ceramic board that allows the use of a low-pollution water-based pen or a marker pen is created and used. In addition, since it uses a marker pen instead of chalk, there may not be a problem of pollution caused by chalk powder. There was a problem that the efficiency of learning could not be achieved due to impaired efficiency, and in the case of the ceracic blackboard, since the blackboard surface is made of ceracic, the chemical resistance is weak when using a marker pen, which makes it difficult to use the blackboard due to poor repellency and eraseability. Problem and you have to replace it with a new product. They were occurred.

따라서 본 발명은 상기한 바와 같은 지금까지의 종래 칠판들의 제반문제점을 감안하여 백묵을 사용하는 칠판과 같은 색깔의 바탕색을 갖는 칠판에 백묵색깔의 수성 또는 마커펜을 사용할 수 있게 함은 물론 운필성과 지움성을 향상시킴으로써 시각적으로 안정감을 주는 기존의 칠판과 같은 색깔의 바탕색으로 되는 칠판을 공해유발 요인이 높은 백묵을 전혀 사용하지 않고서도 사용할 수 있도록 하여 강사나 피교습자 모두가 청결한 상태에서 보다 향상된 학습효과를 기대할 수 있는 마커펜이 사용이 가능한 U,V코팅 칠판의 제조방법을 제공함을 그 목적으로 하는 것으로 첨부도면을 참고로 상세히 설명하면 다음과 같다.Therefore, the present invention allows the use of chalk-based aqueous or marker pens on a blackboard having a background color of the same color as the blackboard using chalk in view of the conventional problems of the conventional blackboards as described above. Improved learning ability allows the board, which is the same color as the existing board to provide visual stability, without using any chalk that has high pollution-causing factors. It can be expected that the marker pen can be used for the purpose of providing a manufacturing method of the U, V coated blackboard as described in detail with reference to the accompanying drawings as follows.

일정크기의 아연도칠판으로 되는 모재(1)의 표면을 탈지제로서 탈지수세한 후 산처리하여 산화피막층(2)을 형성하고, 그 위에 산화규소 70중량%, 산화아연 30중량%의 비율로 혼합한 하도제를 40∼50μ 두께로 도포하여 상온에서 40∼60분 건조경화시켜 하도막층(3)을 이룬다음, 폴리비닐 95중량%, DOP 가소제 3중량%, 티타늄 1중량%, 안정제 1중량%, 녹색 완료가 일정비율로 각각 혼합된 혼합제를 하도막층(3)이 도포된 모재(1)의 상면에 180∼200℃에서 0.12∼0.3㎜의 두께로 롤압착하여 P,V,C 코팅층(4)을 형성하고, 그 표면에 특정모양을 실크인쇄하여 상온에서 30∼40분 동안 건조시킨 다음 그 위에 ULTRA VIOLET 레진 99중량%, 경화제 0.5중량%, 레베링 0.5중량% 비율로 혼합한 유액을 20∼30μ 도포한후 100∼130℃의 자외선으로 20∼30초 경화 건조시켜 U,V 코팅층(5)을 형성한 것을 특징으로 하는 마커펜 사용이 가능한 U,V코팅칠판의 제조방법이다.The surface of the base material 1, which is a certain size of the galvanized sheet, is degreased and washed with a degreasing agent, followed by acid treatment to form an oxide film layer 2, which is mixed at a ratio of 70% by weight of silicon oxide and 30% by weight of zinc oxide. One coat was applied to a thickness of 40-50 μm, and then dried and cured at room temperature for 40 to 60 minutes to form the undercoat layer (3), followed by 95% by weight of polyvinyl, 3% by weight of DOP plasticizer, 1% by weight of titanium, and 1% by weight of stabilizer. P, V, and C coating layers (4) were roll-compressed in a thickness of 0.12 to 0.3 mm at 180 to 200 ° C. on the upper surface of the base material 1 to which the undercoat layer 3 was applied. ), And silk-printed a specific shape on the surface, dried at room temperature for 30 to 40 minutes, and then mixed with an emulsion of 99% by weight of ULTRA VIOLET resin, 0.5% by weight of curing agent, and 0.5% by weight of levering. 20-30 seconds of curing was performed by applying a UV coating of 30-30 占 폚, followed by drying for 20 to 30 seconds to form the U, V coating layer 5 Capable of using a marker pen as ranging U, a method for manufacturing a V-coated board.

도면중 미설명 부호 6는 모재(1) 뒷면에 접착제를 개재하여 부착되는 보강재를 나타낸다.In the figure, reference numeral 6 denotes a reinforcing member attached to the back of the base material 1 through an adhesive.

상술한 본 발명에 의한 마커펜사용이 가능한 U,V코팅 칠판의 제조방법에 대해 보다 상세히 설명하기로 한다.It will be described in more detail with respect to the manufacturing method of the U, V-coated blackboard that can be used marker pen according to the present invention.

먼저 코일상(coi1 狀) 또는 판상(sheet 狀)으로 되며 U,V 재와 친화력이 우수한 아연도칠판을 일정크기로 절단하여 모재(1)를 구성한다. 그다음 상기 모재(1)가 함유하고 있는 이물질을 제거하기 위해 가성소다를 주원료로 하는 탈지제를 이용하여 모재(1)의 표면을 탈지수세한 후 하도제의 접착성을 좋게하기 위하여 모재(1) 표면을 산처리하여 산화피막층(2)을 형성한다.First, the base material 1 is formed by cutting the galvanized plate into a coil shape (coi1 狀) or plate shape (sheet 狀) and having excellent affinity with U and V materials. Then, using a degreasing agent containing caustic soda as a main raw material to remove the foreign substances contained in the base material (1), the surface of the base material (1) in order to improve the adhesiveness of the base material after degreasing washing the surface of the base material (1) Acid treatment to form an oxide film layer (2).

이와같이 모재(1) 표면의 모든 이물질이 제거되고 산화피막층(2)이 형성된 상태에서 산화규소 70중량%, 산화아연 30중량%의 비율로 각각 혼합한 하도제를 40∼50μ두께로 모재(1)의 표면에 골고루 도포한 후 상온에서 40∼60분 건조경화시켜 하도막층(3)을 이룬다. 이때 상기 하도막층(3)의 내열온도는 600℃ 정도로 내열성이 우수한 상태로 된다.Thus, in the state in which all the foreign substances on the surface of the base material 1 were removed and the oxide film layer 2 was formed, the base material 1 to 40-50 micrometers thickness which were respectively mixed by the ratio of 70 weight% of silicon oxide and 30 weight% of zinc oxide is respectively. After coating evenly on the surface of the to form the undercoat layer (3) by drying for 40 to 60 minutes at room temperature. At this time, the heat resistance temperature of the undercoat layer 3 is in a state of excellent heat resistance at about 600 ℃.

이후 폴리비닐 95중량%, DOP 가소제 3중량%, 티타늄(지당) 1중량%, 안정제 1중량%, 녹색완료가 열정비율로 각각 혼합된 혼합제를 하도막층(3)이 도포된 모재(1)의 상면에 180∼200℃에서 0.12∼0.3㎜의 두께로 롤압착하여 P,V,C 코팅층(4)을 형성하는데, 상기 P,V,C 코팅층(4)을 형성할 때 사용되는 폴리비닐 대신에 본 고안에서는 열가소성수지(폴리스티렌, 폴리에틸렌, 폴리프로필렌등)는 어느것이나 선택하여 사용할 수 있음은 물론이다.Thereafter, 95% by weight of polyvinyl chloride, 3% by weight of DOP plasticizer, 1% by weight of titanium (per fat), 1% by weight of stabilizer, and the green material were mixed in a passion ratio, respectively, of the base material (1) to which the undercoat layer (3) was applied. Roll-compress the upper surface to a thickness of 0.12 to 0.3 mm at 180 to 200 ° C. to form a P, V, C coating layer 4, in place of the polyvinyl used to form the P, V, C coating layer 4 In the present invention, of course, any thermoplastic resin (polystyrene, polyethylene, polypropylene, etc.) can be selected and used.

상기와 같이 P,V,C 코팅층(4)을 형성한 후에 칠판에 일반적으로 그려지는 행(行) 간격선, 오선, 방안지, 스게일(scale)등의 문양을 실크인쇄하여 상온에서 30∼40분 동안 건조 시킨후 그 위에 ULTRA VIOLET 레진 99중량%, 경화제(건조첨가제) 0.5중량%, 레베링(평활성유지) 0.5중량% 비율로 혼합한 유액을 20∼30μ의 두께로 도포한 후 100∼130℃의 자외선으로 20∼30초 정도 경화 건조시켜 U,V코팅층(5)을 형성한 것으로써 본 발명에 의한 칠판은 제작되는 것으로서, 이후 칠판의 모재(1) 뒷면에 우레탄 재로 판상으로 된 보강재(6)를 접착제를 개재하여 덧대어 열융착함으로써, 칠판의 중량을 경량화 함은 물론 휨 강도를 강화시켜 치판이 휘거나 변형되는 것을 효과적으로 억제하여 칠판의 수면을 연장할 수 있도록 한 것이다.After forming the P, V, C coating layer (4) as described above, the patterns such as line spacing lines, erroneous lines, squares, scales, and the like, which are generally drawn on a blackboard, are silk-printed at room temperature at 30 to 40 degrees. After drying for 20 minutes, a mixture of 99% by weight of ULTRA VIOLET resin, 0.5% by weight of curing agent (drying additive) and 0.5% by weight of levering (smoothing oil) was applied to a thickness of 20 to 30μ, and then 100 to 130 The board according to the present invention is formed by curing and drying for about 20 to 30 seconds with ultraviolet rays of ℃ to form a U, V coating layer (5), and then a reinforcing material having a plate shape of urethane material on the back of the base material (1) of the board ( By heat-sealing 6) through an adhesive, the weight of the board is reduced, and the flexural strength is enhanced to effectively suppress the bending or deformation of the board, thereby extending the surface of the board.

상술한 칠판에 있어 P,V,C 코팅층(4)의 접착성을 좋게하기 위해 모재(1) 표면을 산처리하여 형성되는 산화피막층(2) 대신에 모재(1) 표면을 샌딩처리하여 표면에 미세한 요철층을 형성함으로써 하도제가 보다 확실하게 접착될수 있도록 하였다.In the above-described blackboard, the surface of the base material 1 is sanded instead of the oxide film layer 2 formed by acid treatment of the surface of the base material 1 in order to improve the adhesion of the P, V, and C coating layers 4. By forming a fine concavo-convex layer, the primer was able to be bonded more reliably.

그리고 본 발명의 칠판을 이루는 모재(1)로서 아연도칠판을 사용하였기 때문에 칠판을 필기판으로서 뿐만 아니라 자석교재를 이용하기 위한 하나의 자성체판으로서 사용할 수도 있으므로 학습효과릍 배가 시킬 수 있는 장점이 있다.In addition, since the zinc painted board is used as the base material (1) forming the blackboard of the present invention, the blackboard may be used not only as a writing board but also as a magnetic board for using a magnetic teaching material, thereby increasing the learning effect. .

이상의 설명에서 알수 있듯이 본 발명의 마커펜 사용이 가능한 U,V 코팅 칠판의 제조방법에 의하면, 일반칠판과 동일한 색깔의 바탕색을 갖되 필기구를 백묵이 아닌 수성펜이나 마커펜을 사용할 수 있도록 그 표면을 U,V 코팅 처리함으로써 운필성과 지움성을 배가 시키고 백묵사용에 따른 제반불편으로 부터 벗어날수 있게 되는 동시에 피교습자 입장에서도 시각적으로 전혀 피로감을 느끼지 않고 보다 안정적인 상태에서 강의가 이루어질수 있으므로 능률적인 학습효과를 기대할 수 있게 되는 것이다.As can be seen from the above description, according to the manufacturing method of the U and V-coated blackboards in which the marker pen of the present invention can be used, the surface of the U-V coating board has the same color as that of a general blackboard but the writing utensil can be used as an aqueous pen or a marker pen instead of chalk. In addition, the V coating process doubles the clarity and eraseability, frees you from all the inconveniences of using chalk, and gives you a more stable learning experience without any visual fatigue from the participant's point of view. It will be possible.
