Description
본 발명은 보온판재 및 그 제조방법에 관한 것으로, 보다 상세하게는, 건축물의 벽체 보온에 사용되는 보온판재 및 그 제조방법에 관한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating plate and a method of manufacturing the same, and more particularly, to a heat insulating plate used for insulating a wall of a building and a method of manufacturing the same.
건축 에너지 절약은 국가 환경 보호 집행과 에너지 절약 정책의 주요 내용이고, 국민 경제의 지속적 발전의 중요한 부분이다. 우리나라는 건축 에너지 절약을 매우 중시하고, 국가의 일련의 에너지 절약 정책, 기준 및 강제성 조문의 지도하에, 우리나라 주책 건축의 에너지 절약 사업은 계속 심화되고 있고, 에너지 절약 기준은 부단히 높아지고 있으며, 건축의 에너지 절약률에 대한 강제성 요구는 50%보다 낮지 않고, 관련 자료가 표명하듯이 벽의 열 전도가 야기하는 에너지 손실은 건축 총 소모 에너지의 약 1/3 가량을 차지하고, 따라서 벽체 보온의 건축 에너지 절약의 중요한 요소이고, 동시에 전통적인 건축 보온 재료는 이미 미래의 발전에 부합하지 않게 되었다.Architectural energy conservation is a major part of national enforcement and energy conservation policies and is an important part of the sustainable development of the national economy. Our country places great emphasis on building energy conservation and under the guidance of a series of national energy conservation policies, standards and compulsory provisions, energy conservation projects in our country are increasingly becoming more and more energy conservation standards are steadily rising, The compulsory requirement for the saving rate is not lower than 50%, and as the related data shows, the energy loss caused by the thermal conduction of the wall accounts for about 1/3 of the total consumption energy of the building, At the same time, traditional building warming materials have already failed to meet future developments.
일반적으로 건축물의 외벽 보온의 절약 재료로 유기 보온 재료 및 무기 보온 재료의 두 종류로 나눌 수 있다. 유기 보온 재료는 방화 및 단열의 효과가 비교적 좋더라고, 사용에 의해 그 사용 수명이 비교적 짧음이 증명되고, 사용 시간의 증가에 따라 그 보온 성능이 부단히 감소한다. 무기 보온 재료는 불연재료에 속하고, 외벽 보온 재료의 발전 추세 및 국가 상관 법규, 정책의 요구에 부합되나, 보온 성능의 차이가 비교적 크다, 일반적으로 사용되는 석면 및 유리면 제품은 단위 중량이 낮고, 내압 강도가 약하고, 그 외변 보호 시공의 응용이 제한된다. 발수성 펄라이트 판의 열전도율이 비교적 낮으나, 이러한 제품은 깨지고 쉽고, 전체 강도가 좋지 않다. 게다가, 현재 각 무기 보온 재료의 생산 공정상, 대다수 비연속화 생산 방식을 채택하여, 생산 효율이 비교적 낮다.Generally, it can be divided into two kinds of organic insulation material and inorganic insulating material as a material for saving the outer wall insulation of a building. The organic insulating material has a relatively good effect of fireproofing and thermal insulation, and its service life has been proved to be relatively short by use, and the insulating performance is steadily reduced with an increase in use time. Asbestos and glass products generally have a low unit weight, and they are used in a wide range of applications. In general, asbestos and glass products are low in unit weight, The pressure resistance strength is weak, and the application of the outer side protection construction is limited. Although the thermal conductivity of the water repellent pearlite plate is relatively low, such a product is easy to break, and the overall strength is poor. In addition, the production process of each inorganic thermal insulation material adopts the most non-sequential production method, and the production efficiency is relatively low.
발포 펄라이트는 양질의 무기 보온 재료이고, 국내외 모두 대량 사용된다. 일례로, 기존의 보온판재의 조성은 발포 펄라이트, 시멘트, 석고가루, 섬유, 재분산 가능한 고무 분말, 카세인(Casein) 등을 포함한다. 상기 특허는 폐기공 발포 펄라이트를 주요 재료로 사용하고, 비록 펄라이트의 미세 가공 구조에 의한 다량의 점착제 사용이 요구되는 문제를 해결할 수 있지만, 상기 보온판재는 여전히 대량으의 석고가루를 사용해야 해서 단위 중량이 과도하게 큰 문제가 존재하고, 또한 여전히 습한 상태에서 성형이 용이하지 않은 단점이 존재한다.
Foamed pearlite is a high-quality inorganic heat-insulating material, and is used in large quantities both at home and abroad. For example, the composition of the conventional heat insulating plate includes foamed pearlite, cement, gypsum powder, fiber, redispersible rubber powder, casein and the like. Although the patent discloses using a pelletized expanded pearlite as a main material and solving the problem of requiring the use of a large amount of pressure-sensitive adhesive due to the fine processing structure of pearlite, the heat insulating plate still needs to use a large amount of gypsum powder, There is an unduly large problem, and there is still a disadvantage that molding is not easy in a wet state.
본 발명의 기술적 과제는, 종래 기술에서 유기 보온재를 사용함에 따라 수명이 비교적 짧은 문제를 해결하고, 나아가 경량, 방화, 단열 기능을 갖는 보온판재 및 그 제조방법을 제공하는 것이다.The technical problem of the present invention is to solve the problem that the lifetime is relatively short due to the use of the organic insulating material in the prior art, and further to provide a heat insulating plate having a lightweight, fireproof and heat insulating function and a manufacturing method thereof.
본 발명이 이루고자 하는 기술적 과제는 이상에서 언급한 기술적 과제로 제한되지 않으며, 언급되지 않은 또 다른 기술적 과제들은 아래의 기재로부터 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에게 명확하게 이해될 수 있을 것이다.
