Description

정보표시용 석재판의 제조방법 및 이에 제조된 정보표시용 석재판{The manufacture method of stone slab for information display and this produced stone slab for information display}[0001] The present invention relates to a method of manufacturing a stone plate for information display and a method of manufacturing the same,

본 발명은 각종 유용한 정보가 표시된 안내판에 관한 것으로, 보다 구체적으로는 안내판을 사람이 다니는 실내·외 바닥이나 벽면과 동일한 석재로 형성하여 보행에 지장을 주지 않고 어우러지는 심미감과 함께 반영구적이면서도 식별력을 향상시킬 수 있는 정보표시용 석재판의 제조방법 및 이에 제조된 정보표시용 석재판에 관한 것이다.More particularly, the present invention relates to a signboard having various useful information. More specifically, the signboard is formed of the same stone as the indoor or outdoor floor or wall of a person, thereby enhancing discrimination while being semi-permanent, The present invention relates to a method of manufacturing a gypsum board for information display and a gypsum board for displaying information.

통상, 도시가 확장됨에 따라 다양한 도로가 신설되고 지하도와 지하철 및 지하주차장 등 지하공간의 활용과 대형화되는 건물이 증가함에 따라 도로를 주행하거나 보행 시 및 각종 건축물 내에서도 목적지의 위치나 방향 등을 인지할 수 있는 다양한 정보를 필요로 하게 된다. 여기서 주요도로의 도로 명 또는 주요건물의 위치와 지하철 및 지하도와 지하 주차장 등 대형건물의 입·출구와 같이, 도시 시설의 실내·외에서 각종정보를 전달하는 이정표 등의 안내판 및 안내표시가 필요로 하게 된다.Generally, as the city is expanded, various roads are newly installed, and as the use of underground spaces such as underpasses, subways, and underground parking lots and the increase in size of buildings are increased, the user is aware of the location and direction of the destination And the like. Here, signposts such as road names or major building locations on major roads, milestones that transmit various information in and out of urban facilities, such as entrance and exit of large buildings such as subways, underpasses, and underground parking lots, do.

현재, 실외의 차도와 인도 등의 도로상에서는 주로 입식간판형태의 안내판 즉, 도로에 통행에 방해가 되지 않도록 지주기둥을 세워서 일정 높이에 이정표 등의 안내판을 설치하고 있다. 이러한 안내판은 인쇄형식으로 제조됨으로서 비교적 선명하여 시인성이 우수하고 많은 양의 다양한 정보 및 실사의 사진 등을 구현할 수 있다는 점에서 유리할 수 있다. 그러나 지주기둥과 같은 보조 시설물을 설치하여야 하므로 시설비용이 많이 들고 태풍과 같은 기후의 영향에 의해 파손되거나 심지어 낙하하여 인사사고로 이어지는 등 다양한 문제점을 유발하는 단점이 있다.At present, on the roads such as outdoor driveways and sidewalks, a signboard in the form of a standing-up signboard, that is, a signpost, such as a milestone, is installed at a certain height by standing upright pillars on the road so as not to interfere with traffic. Such a guide plate is manufactured in a printing format, which is advantageous in that it is relatively clear, has excellent visibility, and can realize a large amount of various information and real photographs. However, there are disadvantages that it is necessary to install supplementary facilities such as supporting pillars, which causes various problems such as a high cost of facilities, damage due to the influence of climate such as a typhoon, or even falling and leading to personnel accidents.

그리고 지하 공간 및 건축물의 실내에는 소형화된 이정표를 벽면에 부착하거나 간단한 문자나 기호 등을 바닥에 설치하여 보행자가 인지할 수 있도록 하고 있다. 예컨대, 콘크리트의 바닥이나 인도 등의 바닥에는 화살표 및 시각장애인용 점자 블록과 같이 상면에 음각 또는 양각으로 돌출 또는 함몰되게 도형과 문자를 형성하여 필요정보를 전달하고 있다. 하지만 벽면에 부착하는 것은 주위환경과 어울리지 못하여 환경미화의 저해요소로 작용하는 단점이 있다. 그리고 블록 등을 조합하여 지면에 설치하는 것은 표현되는 문자나 도형이 지나치게 크게 되며, 점자와 같이 음각 또는 양각으로 형성하는 것은 주로 조각 형태로 제조됨으로서 그 모양 및 색감을 전달하려는 정보의 양이 단편적이고 제한적이므로 필요정보를 충분하게 전달하지 못하게 되는 문제점이 있다.In the underground space and the interior of the building, a miniature milestone is attached to the wall or a simple character or symbol is installed on the floor so that the pedestrian can recognize it. For example, on the floor of a concrete or a floor of a vehicle, necessary information is conveyed by forming shapes and characters such as an arrow and a braille block for a visually impaired person so as to be projected or depressed on the upper surface with a depressed or depressed shape. However, it is disadvantageous that it adheres to the wall because it does not match the surrounding environment and acts as an obstacle to environmental beautification. In addition, when a block or the like is combined with a ground, characters or shapes to be displayed are excessively large, and when formed in a grainy or embossed form like braille, they are mainly produced in a piece form so that the amount of information to convey the shape and color is fragile There is a problem that sufficient information can not be sufficiently transmitted.

이를 해결하기 위한 일환으로, 한국 등록특허공보 제10-1302699호 "석재 안내판의 제조방법"을 제안하고 있다. 제안된 문헌은 내부식성과 내마모성 및 자연 친화적인 특성을 갖는 석재 안내판을 보행자 도로에 설치하되 석재판의 표면에 각종 안내 정보와 지리정보 등의 다양한 정보를 인쇄하여 표시할 수 있도록 함으로써 시야를 가리고 경관을 해치는 문제를 해결하는 한편, 석재판의 표면에 유리질 유약을 피복시켜 석재판에 실크 스크린 인쇄된 안내정보의 손상이 발생하지 않도록 함으로써 자주 교체하고 수리하여야 하는 문제를 해결하고 있다.In order to solve this problem, Korean Patent Registration No. 10-1302699, entitled " Method for manufacturing a stone guide board "is proposed. The proposed document is to install a stone signboard with corrosion resistance, abrasion resistance and nature friendly characteristics on the pedestrian road, so that various information such as various guide information and geographical information can be printed and displayed on the surface of the stone plate, And the glass plate is coated with a glass glaze on the surface of the gypsum board so as to prevent damage to the guide information printed on the gypsum board by silk screen printing, thereby solving the problem of frequent replacement and repair.

그러나 석재를 700~800℃에서 장시간동안 가열하는 과정을 여러 차례 거침에 따라 소모되는 에너지가 상당하여 전반적인 비용이 증가하게 되는 문제점이 있다. 더욱이 석재를 고온으로 가열함에 있어 만족하는 등가온도로의 제어가 어려워 조직의 급격한 변화를 야기하여 크랙에 의한 불량을 초래하는 문제점이 있다.However, the process of heating the stone at a temperature of 700 to 800 ° C. for a long period of time has a problem in that the energy consumed is considerable and the overall cost is increased. Furthermore, when the stone is heated to a high temperature, it is difficult to control the stone to a satisfactory equivalent temperature, causing a sudden change in the structure, resulting in a defect caused by cracks.

이하, 첨부된 도면을 참조하여 본 발명에 따른 바람직한 실시예를 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명은 정보표시용 석재판의 제조방법에 관련되며, 도 1처럼 준비단계(S10)와 전처리 단계(S20) 및 인쇄단계(S30)와 코팅단계(S40)을 거쳐 도 2처럼 정보표시용 석재판(100)을 제조한다. 본 발명은 공수의 절감과 품질의 향상으로 전반적인 시공자와 보행자의 욕구를 충족시킬 수 있는 것을 주요 요지로 한다.The present invention relates to a method of manufacturing a gypsum board for information display, and comprises a preparation step (S10), a preprocessing step (S20), a printing step (S30) and a coating step (S40) Thereby producing a trial plate 100. The main object of the present invention is to satisfy the desire of the constructor and the pedestrian by reducing the number of airs and improving the quality.

먼저, 본 발명에 따른 준비단계(S10)는 석재(10)를 설정한 크기로 절단한 다음, 표면에 부착된 이물질을 제거한다. 석재(10)의 크기와 종류는 기설치 또는 동 설치될 여타의 자재판과 구획조건 및 표시크기에 따라 결정된다. 즉, 자재판의 종류에 따라 콘크리트로 조형한 인공석 또는 천연 화강석을 3~5cm 두께로 자른 후에 구획조건에 따라 설정한 크기로 절단된다. 절단된 석재(10)는 표면으로 물이나 공기를 분사시켜 잔존하는 이물질을 세척한다.First, in the preparation step S10 according to the present invention, the stone 10 is cut to a set size, and then the foreign substances adhering to the surface are removed. The size and type of the stone (10) are determined according to the other substrate and the partition conditions and display size to be installed or installed. That is, artificial stone or natural granite made of concrete is cut to a thickness of 3 to 5 cm according to the type of the magnetic plate, and then cut to a size set according to the compartment condition. The cut stone 10 is then sprayed with water or air to clean the remaining foreign matter.

이어서 본 발명에 따른 전처리 단계(S20)는 석재(10)의 표면을 40~45℃까지 가열하여 내부 응력을 제거한 다음, 표면에 실리콘계 에멀젼을 도포하여 프라이머층(20)을 형성한다. 석재(10)를 가열시키면, 내부에 함유하고 있는 수분은 증발되면서 분자구조는 팽창되어 조직이 균일화 된다. 여기서 석재(10)의 표면이 가열된 상태에서 프라이머층(20)을 형성하는 것이 좋은데, 내부 응력을 제거할 때와 동일한 온도로 가열하는 것이 좋다. 즉, 석재(10)의 표면온도가 45℃ 이상이면 도포된 프라이머층(20)의 온도상승으로 인하여 건조시간이 증가하게 되고, 40℃ 이하이면 프라이머층(20)이 석재(10)의 조직으로 침투력이 저하되어 접착력이 낮아진다.Next, in the pretreatment step S20 according to the present invention, the surface of the stone 10 is heated to 40 to 45 DEG C to remove internal stress, and then a silicone emulsion is applied to the surface to form a primer layer 20. [ When the stone 10 is heated, water contained therein is evaporated, and the molecular structure is expanded to uniformize the structure. Here, it is preferable to form the primer layer 20 in a state where the surface of the stone 10 is heated. It is preferable to heat the stone 10 to the same temperature as that for removing the internal stress. That is, when the surface temperature of the stone 10 is 45 ° C or more, the drying time is increased due to the temperature rise of the applied primer layer 20. When the surface temperature of the stone 10 is 40 ° C or less, The penetration ability is lowered and the adhesive force is lowered.

이어서 본 발명에 따른 인쇄단계(S30)는 프라이머층(20)의 표면에 세라믹이나 아크릴계 도료를 인쇄하여 정보표시층(30)을 형성한 다음, 표면을 40~45℃까지 가열하여 건조한다. 즉, 프라이머층(20)의 표면에 실사의 사진이나 문자를 공판인쇄방식으로 정보표시층(30)을 형성한다. 여기서 정보표시층(30)의 표면이 60℃까지 급속으로 가열한 후에 표면이 40~45℃까지 자연 냉각하는 것이 좋다.In the printing step S30 according to the present invention, the information display layer 30 is formed by printing ceramic or acrylic paint on the surface of the primer layer 20, and then the surface is dried by heating to 40 to 45 ° C. That is, the information display layer 30 is formed on the surface of the primer layer 20 by photolithography or text on the surface of the primer layer 20 by a stencil printing method. Here, it is preferable that the surface of the information display layer 30 is rapidly heated to 60 deg. C and then the surface is naturally cooled to 40 deg. C to 45 deg.

마지막으로 본 발명에 따른 코팅단계(S40)는 정보표시층(30)의 표면에 코팅액을 분사하여 보호층(40)을 형성한 다음, 상온에서 5~6시간 건조시켜 정보표시용 석재판(100)을 완성한다. 코팅액은 수용성 에폭시수지 35~45중량%, 콜로이드 실리카 35~45중량%, 증류수 18~21중량%, 소포제 2~9중량%로 이루어진 조성물에 경화재를 1:1 중량비로 배합된다. 여기서 콜로이드 실리카는 입자크기 20nm, 불휘발분 20중량%, pH 2.5인 것을 암모니아로 pH 7.5로 조정된 제1콜로이드 실리카와, 입자크기 20nm, 불휘발분 30중량%, pH 13인 것을 암모니아로 pH 7.7로 조정된 제2콜로이드 실리카를 1:1 중량비로 균일하게 혼합한 것을 이용한다. 즉, 내산성과 내알칼리성에 모두 강한 콜로이드 실리카로 조성되어 설치환경에 구애받지 않고 반영구적인 수명을 기대할 수가 있다.Finally, in the coating step S40 according to the present invention, a protective layer 40 is formed by spraying a coating solution on the surface of the information display layer 30, and then dried at room temperature for 5 to 6 hours to form an information display stamper 100 ). The coating solution is blended with a curing agent in a weight ratio of 1: 1 to a composition comprising 35 to 45% by weight of water-soluble epoxy resin, 35 to 45% by weight of colloidal silica, 18 to 21% by weight of distilled water and 2 to 9% by weight of defoamer. The first colloidal silica having a particle size of 20 nm, a nonvolatile content of 20% by weight and a pH of 2.5 was adjusted to pH 7.5 with ammonia, and a colloidal silica having a particle size of 20 nm and a nonvolatile content of 30% And the adjusted second colloidal silica is uniformly mixed at a weight ratio of 1: 1. In other words, it is composed of colloidal silica which is strong both in acid resistance and alkali resistance, so that semi-permanent life can be expected regardless of installation environment.

바람직하게는 환류냉각기와 교반기가 설치된 4구 플라스크에 수용성 에폭시수지 40중량%를 투입한 후 제1콜로이드 실리카 20중량%와, 제2콜로이드 실리카 20중량%가 균일하게 혼합된 콜로이드 실리카 40중량%를 교반하면서 첨가한다. 그리고 수용성 에폭시수지와 콜로이드 실리카가 혼합된 혼합물을 80℃로 승온시킨 후 4시간 반응시킨 다음, 상온으로 냉각한다.40% by weight of a water-soluble epoxy resin is added to a four-necked flask equipped with a reflux condenser and a stirrer, and then 20% by weight of the first colloidal silica and 40% by weight of the colloidal silica uniformly mixed with 20% It is added with stirring. Then, the mixed mixture of the water-soluble epoxy resin and the colloidal silica is heated to 80 ° C., reacted for 4 hours, and then cooled to room temperature.

즉, 아래의 반응식과 같이 수용성 에폭시수지가 산성인 제1콜로이드 실리카와 알칼리성인 제2콜로이드 실리카와 각각 반응하여 내산성과 내알칼리성에 모두 강한 성질을 가지게 된다.That is, the water-soluble epoxy resin reacts with the first colloidal silica which is acidic and the second colloidal silica which is alkaline, respectively, as shown in the following reaction formula, so that it has both properties of acid resistance and alkali resistance.

마지막으로 증류수 19.5중량%를 투입하고 소포제 0.5중량%를 첨가시켜 고르게 교반하여 코팅액 조성물을 완성하고, 완성된 조성물 50중량%와 경화재 50중량%를 혼합하여 보호층(40)용 코팅액을 완성한다.Finally, 19.5% by weight of distilled water is added, 0.5% by weight of a defoaming agent is added, and the mixture is stirred well to complete a coating liquid composition, and the coating liquid for the protective layer 40 is completed by mixing 50% by weight of the finished composition and 50%

한편, 코팅단계(S40)는 정보표시층(30)의 표면으로 유리와 규사 알갱이를 살포한 이후에 코팅액을 분사하여 보호층(40)을 형성하거나, 보호층(40)을 형성한 이후에 유리와 규사 알갱이를 살포한다. 유리 알갱이는 빛의 반사량을 증가시켜 주고, 규사 알갱이는 표면의 마찰을 증가시켜 준다. 따라서 시인성이 향상되면서 미끄러짐에 의한 각종 안전사고를 방지해 준다. 이러한 유리와 규사 알갱이는 살포 순서에 따라 도 3a처럼 정보표시층(30)과 보호층(40)에 모두 형성할 수가 있고, 도 3b처럼 보호층(40)에 형성할 수가 있다. 전자와 후자는 모두 정보표시층(30)과 보호층(40)이 경화하기 이전에 살포해야 유리와 규사 알갱이가 각 층에 포함할 수가 있다.In the coating step S40, the protective layer 40 is formed by spraying a coating liquid after spraying glass and silica particles onto the surface of the information display layer 30, or after the protective layer 40 is formed, And silica sand. Glass grains increase the reflection of light, and silica grains increase surface friction. Therefore, it improves visibility and prevents various safety accidents caused by slipping. The glass and silica particles may be formed on the information display layer 30 and the protective layer 40 as shown in FIG. 3A according to the spraying order, and may be formed on the protective layer 40 as shown in FIG. 3B. Both the former and latter need to be sprayed before the information display layer 30 and the protective layer 40 are cured, so that glass and silica particles can be contained in each layer.

이 밖에도 도 3c처럼 정보표시층(30)의 표면으로 유리 알갱이만을 살포한 이후에 코팅액을 분사하여 보호층(40)을 형성한 다음, 보호층(40)의 표면으로 규사 알갱이만을 살포할 수도 있다. 이 경우 유리와 규사 알갱이가 각 층마다 분리됨에 따라 강도를 향상할 수가 있다.3C, the protective layer 40 may be formed by spraying only the glass particles onto the surface of the information display layer 30, spraying the coating liquid, and spraying silica particles only onto the surface of the protective layer 40 . In this case, the strength can be improved by separating the glass and silica sand particles from each other.

완성된 석재판(100)은 도 4처럼 사람이 다니는 인도에 바닥재로 사용되면서, 각종정보를 전달하는 안내판이나 이정표 역할을 수행할 수가 있다. 따라서 지주기둥과 같은 보조 시설물을 불필요 하므로 주위 환경을 저해하지 않으면서도 설치에 필요한 비용이 감축할 수가 있고 특히, 태풍과 같은 기후의 영향에 의해 파손되거나 낙하 따위로 인한 각종 사고를 예방할 수가 있다.As shown in FIG. 4, the finished stone plate 100 can be used as a flooring material for a person's car, and can serve as a signboard or a milestone for conveying various information. Therefore, it does not need auxiliary facilities such as columns, so it is possible to reduce the installation cost without hindering the surrounding environment. Especially, it is possible to prevent various accidents caused by damage or falling due to the influence of climate such as typhoon.
