Description
본 발명은 내구성이 뛰어난 건축용 단열재 및 그 제조 방법에 관한 것으로, 더욱 상세하게는, 볏짚 및 우레탄 발포수지로 이루어지는 건축용 단열재 및 건조시킨 볏짚을 우레탄 발포수지에 대하여 일정 비율로 배합 후 성형하여 상기 건축용 단열재 조성물을 제조하는 방법에 관한 것이다.The present invention relates to a durable building insulation and a method of manufacturing the same, and more particularly, building insulation and dried rice straw consisting of rice straw and urethane foamed resin in a proportion to the urethane foamed resin and then molded by molding in a predetermined ratio. It relates to a method of preparing the composition.
현재 공장, 주택, 사무실, 저온창고, 기타 건축물을 짓기 위해서는 대량의 스티로폴 단열재와 그 보다 단열성이나 품질이 조금 더 우수한 우레탄 단열재가 보편적으로 사용되고 있다. 그러나 두 제품 모두 인장강도나 압축강도의 부족으로 운반중이나 사용중의 작은 부주의에도 부러지고 파손되는 경우가 종종 있다. 즉 스티로폴이나 우레탄 단열재를 이용하여 양면에 철판이나 합판을 부쳐 조립식 패널을 만들어 조립식 건물을 짓는 경우, 압축강도나 인장강도가 부족하여 폭설을 지탱하지 못하고 무너지는 피해를 입기도 한다. 게다가 스티로폴이나 우레탄 단열재는 석유화합물로서 원자재를 수입에 의존하고 있기 때문에 생산원가가 높은 문제점이 있다.Currently, large quantities of styropol insulation and urethane insulation, which is slightly better in insulation and quality, are commonly used to build factories, houses, offices, low-temperature warehouses, and other buildings. However, both products are often broken and broken due to the lack of tensile or compressive strength, even during minor carelessness during transport or use. In other words, when building a prefabricated panel by using steel plates or plywood on both sides using styropol or urethane insulation, building a prefabricated building may not sustain heavy snow due to lack of compressive strength or tensile strength. In addition, styropol and urethane insulation have a high production cost because they depend on imports of raw materials as petroleum compounds.
최근 환경에 대한 소비자들의 관심 고조로 환경 친화적 건축용 내외장재가 요구되고 있으므로 100% 석유 화합물로서 보편적으로 사용되는 스티로폴 단열재나 우레탄 단열재는 그 석유 화합물의 비율을 최소화할 필요가 있다.Recently, due to the increasing interest of the environment, environmentally friendly building interior and exterior materials are required, so Styropol insulation and urethane insulation, which are commonly used as 100% petroleum compounds, need to minimize the proportion of petroleum compounds.
한편 본 발명자의 기 특허출원 제1998-029084호에 의하여 건축 내외장재로서 볏짚 또는 왕겨를 혼합한 성형제품이 알려져 있으며, 동 특허는 볏짚에 요소수지제의 접착제를 사용하거나 우레탄 발포수지제의 접착제를 사용하여 성형열압착 하는 방법에 의해 제조되는 패널을 그 내용으로 하고 있다.Meanwhile, according to the present inventor's patent application No. 1998-029084, a molded product obtained by mixing rice straw or rice husk as a building interior and exterior material is known, and this patent uses an adhesive made of urea resin or an urethane foam resin adhesive to rice straw.

상기한 바와 같은 목적을 달성하기 위한 본 발명의 건축용 단열재는, 볏짚을 30중량% 내지는 95중량%, 바람직하게는 50중량% 내지는 70중량% 함유하고 단열재 조성물의 나머지 함량이 우레탄 발포수지로 이루어진 것을 특징으로 한다.Building insulation of the present invention for achieving the object as described above, 30% by weight to 95% by weight, preferably 50% by weight to 70% by weight of the straw and the remaining content of the insulation composition made of urethane foamed resin It features.
본 발명의 건축용 단열재를 제조하는 방법은, 건조시킨 볏짚을 10cm 이하, 바람직하게는 50mm 이하로 절단 후 볏짚의 결대로 부수어 가는 실 형태로 만든 후 방부제 처리하여 볏짚을 가공하는 단계(a); 상기 단계(a)에서 가공된 볏짚과 우레탄 발포수지를 분사장치를 이용하여 성형틀에 분사시키는 단계(b); 및 상기 단계(b)에서 성형틀에 분사된 볏짚과 우레탄 발포수지를 10배 내지 40배 정도의 발포배수로 발포시키고, 양생시키는 단계(c)를 포함하여 이루어지는 것을 특징으로 한다.The method of manufacturing a building insulation material of the present invention comprises the steps of processing the rice straw by cutting the dried rice straw to 10cm or less, preferably 50mm or less, and then forming the yarn into a string of broken straw, and then preservative treatment (a); (B) spraying the straw and the urethane foaming resin processed in the step (a) using a spray device; And (c) foaming rice straw and urethane foaming resin sprayed on the mold in the step (b) with a foaming drainage of about 10 to 40 times.
상기의 건축용 단열재 제조 방법 중 단계(b)의 분사장치는 분리된 볏짚 분사장치와 우레탄 발포수지 분사장치 각각을 물리적으로 합체하고 그 분사구를 하나로 단일화시켜 일체형으로 제작하는 것을 특징으로 한다. 단계(c)의 우레탄 발포수지는 10배 내지 40배, 바람직하게는 20배 내지 25배 정도의 발포배수로 발포시키는 것임을 특징으로 하며, 단계(c)의 양생시키는 시간은 30초 내지 3시간임을 특징으로 한다.The injector of step (b) of the building insulation material manufacturing method of the above is characterized in that the rice straw injector and the urethane foam resin injector is physically coalesced, and the injection port is united into one to produce a single body. The urethane foaming resin of step (c) is 10 to 40 times, preferably 20 to 25 times Degree of It is characterized in that the foamed foaming drainage, the curing time of step (c) is characterized in that 30 seconds to 3 hours.
본 발명의 재료가 되는 볏짚은 목재와 같이 단열성이 뛰어나고 우수한 보습효과를 가질 뿐 아니라 환경 친화적이다. 국내뿐 아니라 세계적으로 쌀을 주식으로 하는 나라가 많고, 매년 많은 양의 볏짚이 생산되지만 현재 볏짚의 활용은 극소에 지나지 않고, 나머지는 버려지고 있으므로 본 발명에 의해 버려지는 자원을 재활용하여 건축용 단열재를 생산할 경우 단열재의 내구성을 질적으로 향상시키면서 생산원가도 줄일 수 있다.Rice straw, which is a material of the present invention, has excellent thermal insulation and excellent moisturizing effect as wood, and is environmentally friendly. There are many countries that use rice as a staple in Korea as well as in the world, and a large amount of rice straw is produced every year, but the use of rice straw is only a very small amount, and the rest is thrown away. In production, production costs can be reduced while qualitatively improving the durability of the insulation.
볏짚의 절단 길이는 지나치게 크면 혼합시간이 많이 걸리고 접착제가 용이하게 침투할 수 없으므로 혼합 시간과 용이성을 고려할 때 10cm 이하가 바람직하며, 더욱 바람직하게는 50mm 이하가 적당하다. 볏짚의 함량은 접착제의 함량과 상대적인 관계에 있으므로 단열재의 중량과 강도 및 접착성을 고려할 때 30중량% 내지는95중량%가 적당하며, 더욱 바람직하게는 50중량% 내지는 70중량%로 한다.If the cutting length of the rice straw is too large, it takes a long time to mix and the adhesive cannot easily penetrate, so considering the mixing time and ease, 10 cm or less is preferable, and more preferably 50 mm or less. Since the content of rice straw is related to the content of the adhesive, 30% by weight to 95% by weight is appropriate in consideration of the weight, strength, and adhesion of the insulation, and more preferably, It may be 50 to 70 weight%.
접착제는 볏짚을 고형화 시키고 내구성을 향상시키기 위한 것으로 우레탄 발포수지를 사용한다. 우레탄의 단열성은 이미 공지되어 있으므로, 단열성이 뛰어난 이 두 소재를 함께 사용하면 볏짚의 섬유조직이 접착제에 의하여 결합되어 높은 강도를 발휘할 수 있게 된다. 우레탄 발포수지는 일반적으로 폴리올(polyol)을 주성분으로 하는 예비혼합물(premix) A액과 폴리이소시아네이트(polyisocyanate)를 주성분으로 하는 B액을 일정비율로 혼합, 주입함으로써 만들어진다.The adhesive is used to solidify rice straw and to improve durability. Urethane foam resin is used. Since the thermal insulation of urethane is already known, when the two materials having excellent thermal insulation are used together, the fiber structure of rice straw can be bonded by an adhesive and can exhibit high strength. The urethane foaming resin is generally made by mixing and injecting a premix A liquid containing a polyol as a main component and a B liquid containing polyisocyanate as a main component at a predetermined ratio.
이하, 본 발명의 방법을 실시예에 의하여 더욱 상세히 설명한다.Hereinafter, the method of the present invention will be described in more detail with reference to Examples.
