본 발명은 강화안전거울의 제조방법에 관한 것으로서, 더욱 상세하게는 유리의 열처리작업에 있어 유리의 연화점이하로 가열하되 대류열에 의해 유리 전체를 고르게 간접가열하고 가열된 유리를 제습된 냉각압축공기로 급속냉각하여 유리의 웨이브(wave) 현상을 방지하고 고강도의 내충격 강도와 파쇄시의 안전성을 확보하여 사용자가 상해를 입게되는 안전사고를 미연에 방지할 수 있을 뿐만 아니라, 유리의 평활도가 유지되어 거울에 비치는 투상이 바르게 비춰지도록 한 강화안전거울의 제조방법에 관한 것이다.The present invention relates to a method of manufacturing a reinforced safety mirror, and more particularly, in the heat treatment operation of the glass, the glass is heated below the softening point, evenly indirectly heating the entire glass by convection heat, and the heated glass is dehumidified by cooling and compressed air. Rapid cooling prevents wave phenomena of glass, secures high impact strength and safety during crushing, and prevents safety accidents that injure users, and maintains flatness of glass The present invention relates to a method of manufacturing a reinforced safety mirror in which a projection is correctly reflected.
일반적으로 거울은, 유리의 일면에 반사코팅을 처리하여 사용하는 것으로, 종래 거울의 제조방법을 살펴보면 도 1에 도시된 바와 같이 대형판 유리원판을 세척하여 건조하는 세척건조공정과, 대형 유리원판 뒷표면에 은경작업을 진행하는 은경작업공정과, 은경작업이 진행된 유리원판을 건조하는 건조공정과, 은경작업 이후에 건조한 대형유리판의 표면을 보호하기 위해 도장작업을 진행하는 표면보호도장공정과, 재차 건조하는 건조공정과, 대형 유리판을 재단, 가공, 세척하여 거울을 제조하고 있다.In general, the mirror is used by treating the reflective coating on one surface of the glass. Looking at the manufacturing method of the conventional mirror, as shown in FIG. 1, the washing and drying process of washing and drying the large glass disc, and the rear of the large glass disc The silver mirror work process that performs silver mirror work on the surface, the drying process of drying the glass disc which has been processed by silver mirror work, and the surface protection coating process that performs painting work to protect the surface of the large glass plate dried after silver mirror work; Mirrors are manufactured by drying the drying process and cutting, processing and washing large glass plates.
이러한 공정단계에 의해 제조되는 현재의 거울은 강도가 낮아 쉽게 파손되고 파손될 경우, 날카로운 유리조각들로 파손되기 때문에 인접해 있는 사람에게 상해를 입힐 가능성이 높아 안전상에 문제로 지적되고 있다.The current mirror manufactured by this process step is pointed out as a safety problem because it is low in strength and easily broken and if broken, it is broken by sharp glass pieces, which is likely to cause injury to neighboring people.
또한, 대형유리원판의 뒷면에 먼저, 은경작업과 건조작업을 완료한 상태에서 대형유리원판을 다시 재단, 가공, 세척하여 거울을 제조함에 따라 대형유리판을 재단하거나 가공, 세척하는 작업도중에 대형유리원판이 파쇄되거나 또는 크랙(crack) 이 발생되거나 하여 대형유리원판을 사용하지 못하고 그대로 폐기하게 되어 경제적인 손실을 가져오는 문제점이 있다.In addition, on the back of the large glass disc, the large glass disc is cut during the work of cutting, processing, and cleaning the large glass disc as the mirror is manufactured by cutting, processing, and washing the large glass disc again in the state of completing the silver mirror work and the drying work. This crushed or cracks (crack) is generated, there is a problem that can not be used large glass discs as it is discarded as it is, bringing economic losses.
또한, 종래 거울의 안전상의 문제를 해결하기 위한 여러 가지 방법이 동원되고 있는 바, 일예로 거울 뒷면의 보호막층 뒤에 비닐이나 헝겊을 부착하여 거울의 유리가 깨질 경우에 비닐이나 헝겊에 파손된 유리조각이 달라붙어 있게 하여 인체의 부상을 방지하도록 하고 있으나, 이는 거울이 파손되었을 때의 문제점을 해결하는 것으로, 거울의 강도 저하에 의해 쉽게 파손되는 문제점을 해결할 수 없으며, 추가공정에 의해 작업성 및 생산성이 저하되는 문제점이 있다.In addition, various methods for solving the safety problems of conventional mirrors have been mobilized. For example, when a glass of the mirror is broken by attaching a vinyl or a cloth behind the protective layer on the back of the mirror, glass fragments that are broken on the vinyl or the cloth are broken. This is to prevent the injury to the human body by sticking, but this is to solve the problem when the mirror is broken, it is not possible to solve the problem that is easily broken by the decrease of the strength of the mirror, workability and productivity by the additional process There is a problem of this deterioration.
한편, 특허출원 제2001-37522호인 안전강화거울의 제조방법이 안출된 바 있다. 이는 그 공개된 공보의 청구범위에 게재된 바와 같이, 판유리를 형성하는 단계와, 상기 판유리를 원하는 소정의 크기 및 형태로 재단하는 단계와, 상기 재단된 유리판을 절삭, 펀칭 및 연마 공정 등으로 가공하는 단계와, 상기 가공된 유리판을 세정하는 단계와, 상기 세정된 유리판을 가열로에서 500 ~ 800 ℃의 분위기로 2분 정도 열처리한 후 압축공기로 냉각시켜 강화시키는 단계와, 상기 강화된 유리의 일측면에 은용융액을 코팅하여 은박막으로 된 제1코팅층을 형성하는 단계와, 상기 제1코팅층의 상부 전면에 구리용융액을 코팅하여 구리박막으로 된 제2코팅층을 형성하는 단계 및 상기 제2코팅층이 쉽게 박리되지 않도록 상기 제2코팅층의 상부 전면에 1회 이상의 페인팅 공정에 의해 보호막층을 형성하는 단계로 이루어진다.Meanwhile, a method for manufacturing a safety reinforcing mirror of patent application No. 2001-37522 has been devised. This is achieved by forming a plate glass, cutting the plate glass to a desired size and shape, and processing the cut glass plate by a cutting, punching and polishing process as disclosed in the claims of the published publication. And the step of washing the processed glass plate, heat treating the cleaned glass plate in an atmosphere of 500 to 800 ° C. for 2 minutes in a heating furnace, and then cooling and strengthening the compressed glass plate with compressed air. Forming a first coating layer made of a silver thin film by coating a silver melt on one side, forming a second coating layer made of a copper thin film by coating a copper melt on the entire upper surface of the first coating layer, and the second coating layer A protective film layer is formed by at least one painting process on the entire upper surface of the second coating layer so as not to be easily peeled off.
그러나, 전술한 종래 거울의 제조방법은, 일반적인 강화안전유리 제작방법을 기술한 것으로 일반적인 강화안전유리로는 거울의 상이 일그러짐에 따라 강화안전 거울을 제조할 수 없다는 것이 업계의 통념이다.However, the conventional method of manufacturing a conventional mirror described a general method of manufacturing a tempered safety glass, it is a common belief in the industry that a general tempered safety glass cannot produce a tempered safety mirror due to the distortion of the mirror.
그 이유는, 가열로에서 500 ℃ ~ 800 ℃로 유리를 가열할 경우 유리의 연화점 이상으로 가열되어 유리가 녹는 현상이 발생하게 되고, 또한 가열된 유리를 냉각시에 상온압축공기에 의해 냉각함으로써 유리의 표면에 미세한 굴곡이 형성되기 때문이다.The reason for this is that when the glass is heated at 500 ° C to 800 ° C in a heating furnace, the glass is heated above the softening point of the glass and the glass melts. Also, the glass is cooled by using normal temperature compressed air during cooling. This is because fine bends are formed on the surface.
또한, 가열로의 유리 가열방식이 가열로에 설치된 일자형상의 열선에 의한 복사열에 의해 유리를 직접가열함으로써, 열선에 직하되는 유리표면과 그렇지 않는 유리표면이 각각 다른 온도의 복사열로 가열되기 때문에, 유리표면에 웨이브(wave) 현상이 발생하게 된다.In addition, since the glass heating method of the heating furnace directly heats the glass by radiant heat by a linear heating wire installed in the heating furnace, the glass surface directly below the heating wire and the glass surface that are not directly are heated by radiant heat of different temperatures. A wave phenomenon occurs on the glass surface.
뿐만 아니라, 가열된 유리를 상온압축공기로 냉각시키는 냉각방식은 일반적인 강화안전유리를 제조할 때 사용하는 방식으로 가열된 유리에 대한 압력과 시간이 제습된 냉각압축공기에 의한 냉각방식보다 훨씬 크기 때문에 유리의 표면에 굴곡현상이 일어나는 것을 피할 수 없음에 따라, 거울의 제작이 어려워 강화안전거울을 상품으로 제조하기에는 불가능한 문제점이 있다.In addition, the cooling method for cooling the heated glass with room temperature compressed air is a method used when manufacturing a general tempered safety glass, because the pressure and time for the heated glass is much larger than the cooling method with dehumidified cooling compressed air. As the bending phenomenon cannot be avoided on the surface of the glass, it is difficult to manufacture the mirror, which makes it impossible to manufacture a reinforced safety mirror as a product.
본 발명은 종래 거울이 지닌 문제점들을 해결하기 위해 안출된 것으로서, 가공된 판유리를 가열로에서 유리의 연화점인 650 ℃ 이하로 가열하되, 직접가열이 아닌 대류열에 의한 간접가열에 의해 유리가 동일한 온도로 고르게 가열되도록 하고 가열된 유리를 냉각로에서 제습된 냉각압축공기에 의해 급속냉각함으로써 유리에 대한 고강도의 내충격 강도와 안전성을 확보하여 거울의 파쇄시에 사용자가 상 해를 입게 되는 안전사고를 미연에 방지할 수 있을 뿐만 아니라, 유리의 평활도를 유지하여 개끗한 거울의 영상을 얻을 수 있도록 한 강화안전거울의 제조방법을 제공함에 그 목적이 있다.The present invention has been made to solve the problems of the conventional mirror, the processed plate glass is heated to 650 ℃ or less of the softening point of the glass in the heating furnace, the glass is the same temperature by indirect heating by convection heat rather than direct heating By heating the glass evenly and rapidly cooling the heated glass by the cooling compressed air dehumidified in the cooling furnace, it ensures the high impact strength and safety of the glass and prevents the user from being injured when the mirror is broken. In addition to preventing, it is an object of the present invention to provide a method of manufacturing a reinforced safety mirror to maintain the smoothness of the glass to obtain a clear mirror image.
상기 목적을 달성하기 위한 수단으로 본 발명인 강화안전거울의 제조방법은, 일정한 크기로 판유리를 절단하고 가공, 세척, 건조하는 판유리 가공공정과; 상기 판유리 가공공정에 의해 가공된 유리를 가열로에 인입시켜 유리의 연화점(650 ℃) 이하인 500 ℃ ~ 600 ℃의 온도로 대류열에 의해 간접가열하는 가열공정과; 상기 가열공정에 의해 가열된 유리를 냉각로에 인입시켜 냉각로의 제습된 냉각압축공기에 의해 급속냉각하는 냉각공정과; 상기 가열공정과 냉각공정에 의해 열처리되어 강화된 유리의 일면에 반사막을 도포하고 상기 반사막의 표면에 코팅층을 도포하며 유리의 이면에 보호막을 도포한 후 건조하는 제경공정이 포함되어 이루어진 것을 특징으로 한다.Method for producing a reinforced safety mirror of the present invention as a means for achieving the above object, plate glass processing step of cutting, processing, washing, drying the plate glass to a certain size; A heating step of introducing the glass processed by the plate glass processing step into a heating furnace by indirect heating by convection heat at a temperature of 500 ° C. to 600 ° C. which is below the softening point of the glass (650 ° C.); A cooling step of introducing the glass heated by the heating step into the cooling furnace and rapidly cooling the dehumidified cooling compressed air of the cooling furnace; It is characterized in that it comprises a coating process for applying a reflective film on one surface of the glass strengthened by the heating process and the cooling process, a coating layer on the surface of the reflective film and a protective film on the back surface of the glass and then drying. .
상기와 같은 특징으로 이루어진 본 발명인 강화안전거울의 제조방법은, 가공된 유리를 열처리하여 강화하는 과정이 가열로에 인입된 유리를 직접가열이 아닌 대류열에 의한 간접가열로 가열하되, 유리의 연화점인 650 ℃이하의 온도인 500 ℃ ~ 600 ℃의 범위내에서 유리를 가열할 뿐만 아니라, 가열된 유리를 냉각로에 인입시켜 제습된 냉각압축공기에 의해 급속냉각함으로써, 유리표면에 웨이브 형상이 형성되는 것이 미연에 방지되고 유리의 평활도가 향상되어 깨끗한 거울의 영상을 얻을 수 있을 뿐만 아니라, 거울이 파쇄되더라도 콩알처럼 미세조각으로 분쇄되기 때 문에 일반거울의 날카로운 대형파편에 대한 상해위험을 미연에 방지할 수 있다.In the method of manufacturing the reinforced safety mirror of the present invention having the above characteristics, the process of strengthening by heat treatment of the processed glass is heated by indirect heating by convection heat instead of direct heating, the softening point of the glass In addition to heating the glass within the range of 500 ° C. to 600 ° C., which is a temperature of 650 ° C. or lower, the glass is formed in a wave shape on the glass surface by rapidly cooling the heated glass by introducing it into a cooling furnace. This prevents unevenness and improves the smoothness of the glass to obtain a clear mirror image, and also prevents the risk of injuries to sharp and large fragments of ordinary mirrors, even if the mirror is crushed into fine pieces. can do.

즉, 종래에는 대형유리원판의 이면에 은경작업과 건조작업을 한 후에 다시 대형유리원판을 일정한 크기로 절단하여 가공하는 작업을 진행함으로써, 대형유리원판이 파쇄되거나 또는 크랙이 발생되거나 하였으나, 본 발명은 먼저 대형유리원판을 일정한 크기로 절단하고 가공한 다음 세척하는 판유리 가공공정을 먼저 진행하기 때문에, 작업성이 향상되고 경제적인 낭비를 줄일 수 있다.That is, in the related art, after the silver diameter work and the drying work are performed on the back surface of the large glass disc, the large glass disc is cut and processed to a certain size again, whereby the large glass disc is crushed or cracks are generated. Since the first glass glass processing process is first performed by cutting and processing a large-size glass disc to a certain size and then washing, the workability can be improved and economical waste can be reduced.
상기 가열로의 가열공정은, 판유리 가공공정에 의해 가공된 판유리를 가열로 에 인입시켜 유리의 연화점(650 ℃) 이하인 500 ℃ ~ 600 ℃의 온도로 대류열에 의해 간접가열하는 공정이다.The heating step of the heating furnace is a step of indirectly heating the convex heat at a temperature of 500 ° C. to 600 ° C. which is below the softening point (650 ° C.) of the glass by introducing the plate glass processed by the plate glass processing step into the heating furnace.
