Description
본 발명은 이형제에 관한 것으로, 보다 상세하게는 양생이 완료된 콘크리트를 거푸집으로부터 손쉽게 박리시키는 거푸집의 해체시간 단축이 가능한 이형제에 관한 것이다.The present invention relates to a mold release agent, and more specifically, to a mold release agent that can easily peel off cured concrete from the mold and shorten the dismantling time of the mold.
콘크리트는 압축강도가 크고, 내구성과 내화성 및 차음성 등이 우수하한 장점이 있어 건설 현장에서 많이 사용된다.Concrete is widely used in construction sites because it has high compressive strength and has excellent durability, fire resistance, and sound insulation.
콘크리트 시공은 가설공사 후 설치된 토대 위에 거푸집을 설치하고, 배합된 콘크리트를 타설한 후 양생하는 과정을 거친 다음 양생이 완료된 콘크리트를 성형틀로부터 이탈시키는 과정을 거친다.Concrete construction involves installing a form on the foundation installed after temporary construction, pouring the mixed concrete, curing it, and then removing the cured concrete from the mold.
콘크리트를 성형틀로부터 이탈시키기 위해 종래의 박리제는 폐유를 재생한 폐오일 정제유를 사용하며, 이 과정에서 부착성을 증대시키기 위해 그리스나 송진 등을 혼합시킨다.In order to remove concrete from the mold, conventional stripping agents use refined waste oil recycled from waste oil, and in this process, grease or rosin are mixed to increase adhesion.
그런데 이러한 종래의 박리제는 콘크리트 응결을 저해하기 때문에 특히 동절기에 보양이 어려워 거푸집의 해체시기가 늦어지고, 콘크리트 강도가 확보되지 않은 상태에서 거푸집을 해체하는 경우 표면에 콘크리트 잔여물이 부착되어 보수가 필요하거나 거푸집의 청소가 필요한 문제가 있다.However, since these conventional release agents inhibit the setting of concrete, it is difficult to maintain them, especially in the winter, and the dismantling of the form is delayed. If the form is dismantled without the strength of the concrete secured, concrete residue adheres to the surface, requiring repair. Or, there is a problem that requires cleaning of the formwork.
본 발명은 상기한 바와 같은 종래의 문제점을 해결하기 위한 것으로서, 본 발명의 목적은, 양생이 완료된 콘크리트를 손쉽게 박리시키면서도 콘크리트의 응결을 촉진하여 거푸집의 해체시간 단축이 가능한 이형제를 제공하는 것이다.The present invention is intended to solve the conventional problems as described above. The purpose of the present invention is to provide a release agent that can easily peel off cured concrete and promote setting of the concrete, thereby reducing the dismantling time of the form.
상기 목적은, 폐유를 정제한 정제유 65 내지 97 중량%; 티오시안 나트륨(NaSCN) 1 내지 20 중량%와, 포타슘포메이트(PF), 포타슘아세테이트(PA), 칼슘포메이트(CF), 질산칼륨, 주석산 및 리튬카보네이트로 이루어진 군에서 선택된 어느 하나 이상을 포함하는 혼화제 2 내지 15 중량%를 포함하는 것을 특징으로 하는 거푸집의 해체시간 단축이 가능한 이형제에 의해 달성된다.For the above purpose, 65 to 97% by weight of refined oil obtained by refining waste oil; Contains 1 to 20% by weight of sodium thiocyanate (NaSCN) and at least one selected from the group consisting of potassium formate (PF), potassium acetate (PA), calcium formate (CF), potassium nitrate, tartaric acid, and lithium carbonate. This is achieved by a mold release agent capable of shortening the dismantling time of the mold, which is characterized in that it contains 2 to 15% by weight of an admixture.
본 발명에 따른 거푸집의 해체시간 단축이 가능한 이형제에 의하면, 양생이 완료된 콘크리트를 손쉽게 박리시키면서도 콘크리트의 응결을 촉진하여 거푸집의 해체시간을 단축시킬 수 있다.According to the mold release agent capable of shortening the dismantling time of the form according to the present invention, the dismantling time of the form can be shortened by easily peeling off the cured concrete and promoting the setting of the concrete.
이하, 본 발명의 일부 실시예들을 예시적인 도면을 통해 상세하게 설명한다. 각 도면의 구성요소들에 참조부호를 부가함에 있어서, 동일한 구성요소들에 대해서는 비록 다른 도면상에 표시되더라도 가능한 한 동일한 부호를 가지도록 하고 있음에 유의해야 한다. 또한, 본 발명의 실시예를 설명함에 있어, 관련된 공지 구성 또는 기능에 대한 구체적인 설명이 본 발명의 실시예에 대한 이해를 방해한다고 판단되는 경우에는 그 상세한 설명은 생략한다.Hereinafter, some embodiments of the present invention will be described in detail through illustrative drawings. When adding reference numerals to components in each drawing, it should be noted that identical components are given the same reference numerals as much as possible even if they are shown in different drawings. Additionally, when describing embodiments of the present invention, if detailed descriptions of related known configurations or functions are judged to impede understanding of the embodiments of the present invention, the detailed descriptions will be omitted.
또한, 본 발명의 실시예의 구성 요소를 설명하는 데 있어서, 제1, 제2, A, B, (a), (b) 등의 용어를 사용할 수 있다. 이러한 용어는 그 구성 요소를 다른 구성 요소와 구별하기 위한 것일 뿐, 그 용어에 의해 해당 구성 요소의 본질이나 차례 또는 순서 등이 한정되지 않는다. 어떤 구성 요소가 다른 구성요소에 “연결”, “결합” 또는 “접속”된다고 기재된 경우, 그 구성 요소는 그 다른 구성요소에 직접적으로 연결되거나 접속될 수 있지만, 각 구성 요소 사이에 또 다른 구성 요소가 “연결”, “결합” 또는 “접속”될 수도 있다고 이해되어야 할 것이다.Additionally, when describing the components of an embodiment of the present invention, terms such as first, second, A, B, (a), and (b) may be used. These terms are only used to distinguish the component from other components, and the nature, sequence, or order of the component is not limited by the term. When a component is described as being “connected,” “coupled,” or “connected” to another component, that component can be connected or connected directly to that other component, but there is no need for another component between each component. It should be understood that may be “connected,” “combined,” or “connected.”
이하, 본 발명의 실시예들에 따른 거푸집의 해체시간 단축이 가능한 이형제에 대해 상세히 설명한다.Hereinafter, a mold release agent capable of shortening the disassembly time of the form according to embodiments of the present invention will be described in detail.
본 발명의 일실시예에 따른 이형제는, 폐유를 정제한 정제유 60 내지 70 중량%와, 티오시안 나트륨(NaSCN) 1 내지 20 중량%와, 포타슘포메이트(PF), 포타슘아세테이트(PA), 칼슘포메이트(CF), 질산칼륨, 주석산 및 리튬카보네이트로 이루어진 군에서 선택된 어느 하나 이상을 포함하는 혼화제 10 내지 39 중량%를 포함할 수 있다.The mold release agent according to an embodiment of the present invention includes 60 to 70% by weight of refined oil obtained from refined waste oil, 1 to 20% by weight of sodium thiocyanate (NaSCN), potassium formate (PF), potassium acetate (PA), and calcium. It may contain 10 to 39% by weight of an admixture containing at least one selected from the group consisting of formate (CF), potassium nitrate, tartaric acid, and lithium carbonate.
여기서 티오시안 나트륨(NaSCN)은 콘크리트의 조강성을 증대시킬 수 있으며, 티오시안 나트륨이 20 중량%를 초과하는 경우 점성으로 인해 사용에 어려움이 생길 수 있다.Here, sodium thiocyanate (NaSCN) can increase the crude strength of concrete, and if sodium thiocyanate exceeds 20% by weight, difficulties in use may arise due to viscosity.
그리고 본 발명의 일실시예에 따른 이형제는 포타슘포메이트(PF), 포타슘아세테이트(PA), 칼슘포메이트(CF), 질산칼륨, 주석산 및 리튬카보네이트로 이루어진 군에서 선택된 어느 하나 이상을 포함하는 혼화제를 10 내지 39 중량% 포함할 수 있으며, 포타슘포메이트(PF), 포타슘아세테이트(PA), 칼슘포메이트(CF)는 어는점이 낮아 저온에서 콘크리트의 응결을 촉진시킬 수 있다. 즉, 콘크리트에 혼합되어 사용되는 경우 어는점을 내리면서 강도를 증진시킬 수 있다.And the mold release agent according to an embodiment of the present invention is an admixture containing at least one selected from the group consisting of potassium formate (PF), potassium acetate (PA), calcium formate (CF), potassium nitrate, tartaric acid, and lithium carbonate. It may contain 10 to 39% by weight, and potassium formate (PF), potassium acetate (PA), and calcium formate (CF) have a low freezing point and can promote the setting of concrete at low temperatures. In other words, when mixed and used in concrete, strength can be improved by lowering the freezing point.
이로써, 본 발명에 따른 이형제는 폐유를 정제한 정제유에 콘크리트의 응결을 촉진하기 위한 혼화제를 혼합하여 기존의 콘크리트의 박리제 역할을 수행함과 동시에 콘크리트의 응결을 촉진시켜 거푸집의 해체 시기를 앞당길 수 있다.As a result, the mold release agent according to the present invention mixes refined oil purified from waste oil with an admixture to promote the setting of concrete, thereby acting as a release agent for existing concrete and at the same time promoting the setting of concrete, thereby accelerating the dismantling of the form.
이상에서 설명한 것은 본 발명에 따른 거푸집의 해체시간 단축이 가능한 이형제를 실시하기 위한 실시예에 불과한 것으로서, 본 발명은 상기한 실시예에 한정되지 않고, 이하 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자라면 누구든지 다양하게 변경하여 실시가능한 범위까지 본 발명의 기술적 정신이 있다고 할 것이다.What has been described above is only an example for implementing the mold release agent capable of reducing the disassembly time of the form according to the present invention, and the present invention is not limited to the above-described embodiment and goes beyond the gist of the present invention claimed in the claims below. Without this, anyone with ordinary knowledge in the technical field to which the present invention pertains will say that the technical spirit of the present invention exists to the extent that it can be implemented with various modifications.
