Description
본 발명은 유기용제에 용제가역형 수지를 용해시켜 합판의 표면으로 코팅하여 수지코팅막을 형성하도록 제공하므로 합판과 수지코팅막의 견고한 결속력, 별도의 이형제 없이 시멘트와의 이형성, 수지코팅막의 손상시에 보수 용이성 등에 의해 사용 회수를 최대 반복할 수 있어 경제성과 함께 거푸집 설치 및 탈형 작업성, 신뢰성을 우수하게 제공하는 용제가역형 수지를 이용한 거푸집용 코팅 합판에 관한 것이다.The present invention provides a resin coating film by dissolving a solvent-reversible resin in an organic solvent and coating the surface of the plywood to form a solid binding force between the plywood and the resin coating film, releasability with cement without a separate release agent, repairing when the resin coating film is damaged. The present invention relates to a die-coated plywood using a solvent-reversible resin that can be repeatedly used and reused by ease and the like, and provides excellent mold installation, demolding workability, and reliability.
일반적으로 거푸집 용도로 합판을 주로 사용하고 있다.In general, plywood is mainly used for formwork.
이와 같은 합판은 넓은 면적의 편평도와, 가공성이 용이한 잇점을 갖고 있다.Such plywood has the advantage of flatness of a large area and easy workability.
이와 같은 합판은 주로 단판(베이어)를 수직방향, 수평방향으로 홀수개를 겹쳐 접착하여 제작하게 된다.Such a plywood is mainly produced by adhering an odd number of plates (bayers) to each other in the vertical and horizontal directions.
이와 같은 합판을 단독 또는 유로폼(철재 프레임)에 결합하여 거푸집 용도로 사용하면, 시멘트의 강 알카리에 견디지 못하여 수회 반복 사용이 곤란한 문제점이 있었다.When such a plywood is used alone or in combination with a euro-form (steel frame) for use in formwork, there is a problem in that it cannot withstand the strong alkali of cement and is difficult to use repeatedly.
이를 보완하고자 도 1에 도시된 바와 같이 합판 접착에 사용되는 열 경화성 수지인 페놀을 필름(12) 형태로 합판(10)의 양쪽면에 접착하여 시멘트 타설시 시멘트 액이 안쪽으로 스며들지 못하도록 하므로 반복 사용횟수를 늘리도록 한 것이다.To compensate for this, as shown in FIG. 1, phenol, which is a thermosetting resin used for bonding plywood, is adhered to both sides of the
그러나 상기 필름 접착형 합판의 경우에 필름 형태의 열경화성 수지가 시멘트와 어느 정도 접착성을 가지게 되므로 시멘트 타설 및 양생후 탈형이 용이하지 못하게 되고, 이를 방지하고자 광유나 박리제, 이형제 등을 매번 도포하면서 사용하여야 하는 문제점이 있었다.However, in the case of the film adhesive plywood, since the thermosetting resin in the form of a film has some degree of adhesiveness with cement, it is not easy to demould after cement placing and curing, and is used while applying mineral oil, a release agent, a release agent, etc. every time. There was a problem that should be.
또한, 종래 합판은 주로 나왕을 주 재료로 사용하게 되는데, 나왕의 가공이나 자체 특성상 나무결을 형성하고, 이 나무결상에 열경화성 수지 필름이 접착되어 미세 틈새를 형성하기 때문에 시멘트 타설과, 시멘트의 품질 향상을 위해 시멘트 사이의 공기 빼기를 위해 다짐 작동 등으로 높은 압력과 진동에 의해 필름 표면이 갈라지는 금을 형성하는 문제점이 있었다.In addition, conventional plywood mainly uses Nawang as the main material, and because of the processing or its own characteristics of Nawang, the wood grain is formed, and the thermosetting resin film is adhered to the wood grain to form fine cracks, thereby improving the quality of cement casting and cement. For this purpose, there is a problem in that the film surface is cracked due to high pressure and vibration due to a compaction operation for air extraction between cements.
이와 같이 필름 표면이 갈라지도록 형성되는 금을 통해 시멘트액이 침투하여 필름의 손상은 물론 합판의 손상을 유발하게 되므로 합판의 사용 횟수가 10여회에 이르면 표면이 손상되어 시멘트 타설 및 양생후 탈형이 용이하지 못하게 되는 문제점이 심각하였다.As the cement liquid penetrates through the gold formed to crack the film surface as described above, it causes damage to the film as well as the film. Therefore, when the number of times of use of the plywood reaches 10 times, the surface is damaged to facilitate demolding after cement casting and curing. The problem of not being able to do it was serious.
이 경우에도 상기 합판의 표면에 박리제나 이형제를 매회 도포하면서 사용하여야 하는 문제점이 있었다.Even in this case, there was a problem that it should be used while applying a release agent or a release agent to the surface of the plywood every time.
더우기, 상기와 같이 합판에 박리제나 이형제를 사용하는 경우에는, 상기 박 리제나 이형제를 도포하는 과정중에 철근에 뭍게 되고, 이는 철근과 시멘트의 접착성을 약화시켜 콘크리트의 전단력과 철근의 인장력 등에 큰 문제를 유발하게 되고, 결국 콘크리트 건축물의 부실화를 초래하게 되었다.In addition, when a release agent or a release agent is used on the plywood as described above, it is applied to the reinforcing bar during the application of the release agent or the release agent, which weakens the adhesiveness between the reinforcing bar and the cement, which is great for the shear force of the concrete and the tensile strength of the bar. It caused problems, and eventually led to the deterioration of concrete structures.
그 밖에 상기한 종래 합판의 문제점을 해결하고자 PET(Polyethylen terephthalate) 필름을 50~100㎛로 얇게 제조하여 열 압착하여 사용하였으나 이는 열악한 건축현장에서 한번 흠집이 형성된 곳이 지속적으로 커져 그 곳으로 시멘트액이 침투되어 결국 수명을 단축시키는 문제점이 여전하였고, 또한 주제와 경화제로 분리된 2액형의 불포화포리에스터를 합판 표면에 도포하여 사용하였으나 이는 경도가 너무 높아 모 작업 등을 하면 깨져 버리는 단점과 두께가 상당히 두꺼워야 제 기능을 하게 되는 문제점이 여전하였다.In addition, in order to solve the problem of the conventional plywood, PET (polyethylene terephthalate) film was manufactured by using 50 to 100 탆 thin and thermally compressed, but this was used in the poor construction site where the scratches were continuously enlarged and the cement liquid therein. This penetrates and eventually shortens the lifespan. Also, two-component unsaturated polyesters separated from the main body and the curing agent were applied to the surface of the plywood, but the hardness was too high. It still had to be thick enough to function properly.
그리고 상기한 페놀필름, PET, 불포화포리에스터 코팅 등은 훼손시에 보수가 불가능한 단점을 모두 갖고 있었다.And the phenol film, PET, unsaturated polyester coating, etc. had all the disadvantages that can not be repaired at the time of damage.
본 발명은 상기한 종래 기술이 갖는 제반 문제점을 해결하고자 발명된 것으로서, 유기용제에 용제가역형 수지를 용해시켜 합판의 표면으로 코팅하여 수지코팅막을 형성하도록 제공하므로 합판과 수지코팅막의 견고한 결속력, 별도의 이형제 없이 시멘트와의 이형성, 수지코팅막의 손상시에 보수 용이성 등에 의해 사용 회수를 최대 반복할 수 있어 경제성과 함께 거푸집 설치 및 탈형 작업성, 신뢰성을 우수하게 제공하는데 그 목적이 있다.The present invention has been invented to solve all the problems of the prior art described above, so as to provide a resin coating film by dissolving a solvent reversible resin in an organic solvent to form a coating film of plywood, a solid binding force between the plywood and the resin coating film, separate Its purpose is to provide excellent mold installation, demolding workability and reliability with economical efficiency because the number of times of use can be repeated by release property with cement and ease of repairing when the resin coating film is damaged without the release agent.
이러한 본 발명은,This invention,
유기용제 100중량부에 용제가역형 수지 20~40중량부를 녹여 거푸집용 합판의 표면으로 다수 반복 코팅하되, 상기 코팅액중 유기용제가 증발하여 거푸집용 합판의 표면으로 수지코팅막을 형성하여 제공함에 그 특징이 있다.20 to 40 parts by weight of a solvent reversible resin is dissolved in 100 parts by weight of an organic solvent, and the coating is repeatedly applied to the surface of the formwork plywood, and the organic solvent in the coating solution is evaporated to form a resin coating film on the surface of the formwork plywood. There is this.
본 발명의 상기 유기용제는 아세톤, 메틸에틸케톤(Methyl Ethyl Ketone), 메틸이소부틸케톤(Methyl Isobutyl Ketone), 톨루엔으로 이루어진 그룹으로 부터 선택되고, 상기 용제가역형 수지는 ABS수지, 아크릴 수지로 사용함에 그 특징이 있다.The organic solvent of the present invention is selected from the group consisting of acetone, methyl ethyl ketone, methyl isobutyl ketone, toluene, and the solvent reversible resin is used as an ABS resin or an acrylic resin. Has its features.
본 발명의 상기 거푸집용 합판 표면의 수지코팅막으로 다시 유기용제에 용제가역형 수지를 용해한 용해액을 덧칠하여 표면 손상을 보수하도록 사용함에 그 특징이 있다.The resin coating film of the surface of the die plywood of the present invention is characterized in that it is used to repair surface damage by repainting the dissolved solution in which the solvent reversible resin is dissolved in the organic solvent.
이러한 본 발명은 유기용제에 용제가역형 수지를 용해시켜 합판의 표면으로 코팅하되, 상기 융기용제가 증발하여 수지코팅막을 형성하도록 제공하므로, 합판과 수지코팅막의 견고한 결속력, 별도의 이형제 없이 시멘트와의 이형성, 수지코팅막의 손상시에 보수 용이성 등에 의해 사용 회수를 최대 반복할 수 있어 경제성과 함께 거푸집 설치 및 탈형 작업성, 신뢰성을 우수하게 제공하는 효과를 갖는 것이다.The present invention is to dissolve a solvent reversible resin in an organic solvent and to coat the surface of the plywood, the ridge solvent is provided to evaporate to form a resin coating film, the solid binding strength of the plywood and the resin coating film, without a separate release agent with cement The number of times of use can be repeated at the time of the release property and the damage of the resin coating film due to the ease of repair and the like, and it has the effect of providing excellent mold installation, demoulding workability, and reliability.
이하, 상기한 본 발명에 대해 좀더 구체적으로 살펴보기로 한다.Hereinafter, the present invention will be described in more detail.
본 발명의 거푸집용 합판은 유기용제에 용제가역형 수지를 용해시켜 합판의 표면으로 코팅하되, 상기 융기용제가 증발하여 수지코팅막을 형성하도록 제공하는 것이다.Formwork plywood of the present invention is to dissolve a solvent reversible resin in an organic solvent to be coated on the surface of the plywood, to provide a resin coating film to evaporate the raised solvent.
이와 같은 거푸집용 합판 표면의 수지코팅막은 표면 손상시에 유기용제에 용제가역형 수지를 용해한 용해액을 다시 덧칠하여 보수 가능하도록 제공하는 것이다.The resin coating film on the surface of the formwork plywood is to be repaired by repainting the dissolved solution of the solvent reversible resin in the organic solvent at the time of surface damage.
즉, 본 발명의 거푸집용 합판은 유기용제 100중량부에 용제가역형 수지 20~40중량부를 녹여 거푸집용 합판(10)의 표면으로 다수 반복 코팅하되, 상기 코팅액중 유기용제가 증발하여 거푸집용 합판의 표면으로 수지코팅막(20)을 형성하도록 이루어진다.That is, the die plywood of the present invention is dissolved in 20 to 40 parts by weight of a solvent reversible resin in 100 parts by weight of the organic solvent and repeatedly coated on the surface of the
이때, 상기 유기용제는 아세톤, 메틸에틸케톤(Methyl Ethyl Ketone), 메틸이소부틸케톤(Methyl Isobutyl Ketone), 톨루엔 및 이와 유사 성질의 그룹으로 부터 선택되고, 상기 용제가역형 수지는 ABS수지, 아크릴 수지 및 이와 유사 성질의 그룹으로 부터 선택된다.In this case, the organic solvent is selected from the group of acetone, methyl ethyl ketone, methyl isobutyl ketone, toluene and similar properties, and the solvent reversible resin is ABS resin, acrylic resin. And similar properties.
또한, 상기 용제가역형 수지가 20 중량부 미만으로 용해하면, 용해액이 너무 묽어 합판 표면에 코팅시에 수지코팅막을 일정 두께로 형성함이 어렵고, 40 중량부초과로 용해하면, 용해액이 너무 걸죽하게 되어 합판 표면 코팅시에 수지코팅막을 일정 두께로 넓은 면적에 고르게 조절 형성함이 어렵우므로 상기 용제가역형 수지는 20~40중량부로 형성함이 바람직하다.In addition, when the solvent-reversible resin is dissolved in less than 20 parts by weight, the solution is too thin, it is difficult to form a resin coating film to a certain thickness at the time of coating on the surface of the plywood, when dissolved in excess of 40 parts by weight, the solution is too It is preferable to form the solvent reversible resin in an amount of 20 to 40 parts by weight, since it is difficult to control the resin coating film evenly in a large area at a predetermined thickness when coating the plywood surface.
또한, 본 발명의 상기 거푸집용 합판 표면의 수지코팅막은 수지코팅막의 손상시에 수지코팅막 표면으로 다시 유기용제에 용제가역형 수지를 용해한 용해액을 덧칠하여 수지코팅막에 덧칠한 수지가 용해되어 보수하도록 제공하는 것이다.In addition, the resin coating film of the surface of the formwork plywood of the present invention to the resin coating film surface when the resin coating film is damaged by repainting the dissolving solution dissolved in the solvent reversible resin in the organic solvent to dissolve and repair the resin coated on the resin coating film To provide.
다음은 상기한 본 발명의 거푸집용 합판의 작용에 대해 설명하기로 한다.Next will be described the operation of the formwork plywood of the present invention described above.
본 발명의 거푸집용 합판은 아세톤, 메틸에틸케톤(Methyl Ethyl Ketone), 메틸이소부틸케톤(Methyl Isobutyl Ketone), 톨루엔 등으로 이루어진 그룹으로 부터 선택된 유기용제 100중량부에 ABS수지, 아크릴 수지 등으로 이루어진 그룹으로 부터 선택된 용제가역형 수지 20~40중량부를 녹인 용해액을 거푸집용 합판의 표면으로 다수 반복 코팅한다.Formwork plywood of the present invention is 100 parts by weight of an organic solvent selected from the group consisting of acetone, methyl ethyl ketone, methyl isobutyl ketone, toluene, ABS resin, acrylic resin, etc. Dissolve a solution of 20 to 40 parts by weight of a solvent-reversible resin selected from the group is repeatedly coated on the surface of the die plywood.
이와 같이하면, 상기 용해액 중에 유기용제가 휘발성에 의해 증발하고, 상기 거푸집용 합판(10)의 표면으로 수지코팅막(20)을 형성하게 되는 것이다.In this way, the organic solvent in the solution is evaporated due to volatility, and the
이때, 상기 용해액은 합판의 다공성 조직 사이로 침부하기 때문에 도 2에 도 시된 바와 같이 합판과의 접착성이 우수하게 제공되는 것이다.At this time, since the solution is immersed between the porous tissue of the plywood is to provide excellent adhesion to the plywood as shown in FIG.
이와 같이 제조된 본 발명의 거푸집용 합판을 이용하여 콘크리트 타설하게 되면, 상기 수지코팅막은 유기재료로 내 알카리성을 갖기 때문에 별도의 이형제 도포 없이도 무기재료인 시멘트와 접착이 방지되는 이형성을 기본적으로 갖기 때문에 작업성이 간편함은 물론 이형제 및 이형제 도포작업에 소요되는 비용의 절감으로 경제성을 우수하게 제공한다.When the concrete is poured using the formwork plywood of the present invention prepared as described above, since the resin coating film has alkali resistance as an organic material, since it has a mold release property to prevent adhesion with cement, which is an inorganic material, without applying a separate release agent, Not only is the workability simple, but also the economics are excellent due to the reduction of the cost of the release agent and the release agent application.
또한, 상기 수지코팅막이 시멘트와 접착이 방지되는 이형성을 갖기 때문에 거푸집용 합판의 탈형 작업이 간편하게 됨은 물론 탈형 작업시에 합판 표면의 수지코팅막 손상을 최소화하게 되는 것이다.In addition, since the resin coating film has a releasability to prevent adhesion with cement, it is easy to demold the formwork plywood and minimize damage of the resin coating film on the surface of the plywood during the demolding operation.
더우기, 상기 합판 표면의 수지코팅막이 손상되더라도, 종래 페놀이나 PET 등을 필름 형태로 합판에 접착한 경우와 달리 보수가 가능한데, 이는 상기 유기용제에 용제가역형 수지를 녹인 용해액을 수지코팅막의 표면으로 덧칠하여 용제가역형 수지가 일체로 덧칠되면서 손상 부위를 보수하게 되는 것이다.Moreover, even if the resin coating film on the surface of the plywood is damaged, it can be repaired unlike the case where conventional phenol or PET is adhered to the plywood in the form of a film, which is a surface of the resin coating film of a solution in which the solvent-reversible resin is dissolved in the organic solvent. By repainting, the solvent reversible resin is repainted integrally to repair the damaged area.
즉, 거푸집 합판의 지속적인 보수가 가능하여 사용 수명을 장구히 하게 되는 것이다.In other words, it is possible to maintain the formwork plywood long life.
