Description
본 발명은 친환경 건축소재용 조성물 및 이의 제조방법에 관한 것으로, 더욱 상세하게는 인체에 무해하면서 다양한 분야의 건축소재로 사용될 수 있는 친환경 건축소재용 조성물 및 이의 제조방법에 관한 것이다. The present invention relates to a composition for eco-friendly building materials and a method for manufacturing the same, and more particularly, to a composition for an eco-friendly building material which is harmless to the human body and can be used as a building material in various fields.
일반적으로 건물의 내외부를 깨끗하게 마감하는 건축소재에는 벽재, 천정재, 장식재, 마감재 등이 있다. 기존의 건축소재는 가연성 플라스틱이나 목재 또는 시멘트 및 석고분에 석면을 혼합하여 제조된 석고보드가 주로 사용되었다.Generally, building materials that finish the interior and exterior of a building cleanly include wall materials, ceiling materials, decorative materials, and finishing materials. Conventional construction materials were mainly made of gypsum board made by mixing asbestos with flammable plastic, wood or cement and gypsum.
이들 건축소재는 화재시에 각종 유독가스를 발생시키는 동시에 화재를 확산시켜 많은 재산과 인명피해를 발생시켰고, 또한 건축소재를 불연성의 새로운 자원으로 사용하게 되더라도 건축 비용이 상승함과 동시에 자원의 낭비와 새집 증후군 등의 여러 가지 문제점을 초래하였다. These architectural materials generate various toxic gases at the same time as fire and spread fire, resulting in a lot of property and personal injury, and even if the building material is used as a new nonflammable resource, the construction cost rises and at the same time, Sick house syndrome and so on.

이러한 구성에 의해, 본 발명의 일실시예에 따라 친환경 건축소재용 조성물을 제조하는 과정을 설명하면 다음과 같다.With this structure, a process for manufacturing a composition for an eco-friendly building material according to an embodiment of the present invention will be described.
우선, 물 100중량부에 질산 11~19중량부를 넣어 잘 교반하여 혼합하고, 여기에 마그네슘 3~7중량부를 조금씩 떨어뜨리면 수증기가 발생하며 끓어오르게 된다. 이때, 마그네슘을 계속 조금씩 넣어주면 점차 투명해지는데 수증기가 증발한 만큼의 물을 따로 보충해주며 1시간 정도 반응시킨 상태로 놓아두면 나중에는 물처럼 투명해지고 이렇게 함으로써 기초액을 조성한다. First, 11 to 19 parts by weight of nitric acid is added to 100 parts by weight of water, and the mixture is mixed with stirring. When 3 to 7 parts by weight of magnesium is dropped little by little, steam is generated and boiled. At this time, if the magnesium is continuously added little by little, it gradually becomes transparent. It replenishes water as much as vaporized vapor, and if it is left in a state of reacting for about 1 hour, it becomes transparent like water afterwards.
다음에, 물 100중량부에, 산화나트륨 14~21중량부, 이산화규소 45~56중량부, 산화철 0.03~0.07중량부, 분산제 0.3~0.9중량부를 넣고 가열교반기에서 60~90 ℃의 온도로 20분간 서서히 가열 교반하여 혼합한다. Next, 14 to 21 parts by weight of sodium oxide, 45 to 56 parts by weight of silicon dioxide, 0.03 to 0.07 part by weight of iron oxide and 0.3 to 0.9 part by weight of a dispersing agent were added to 100 parts by weight of water, and 20 parts by weight of 20 The mixture is gradually stirred with heating for a minute.
그리고, 상기 물에 산화나트륨, 이산화규소, 산화철, 분산제가 혼합된 물질에 탄산마그네슘 1.6~5.2중량부와 상기 기초액 4~9중량부를 서서히 떨어뜨려 혼합하되, 혼합되는 물질에서 수증기가 나올 때까지 교반하여 혼합한다. Then, 1.6 to 5.2 parts by weight of magnesium carbonate and 4 to 9 parts by weight of the base liquid are gradually added to and mixed with the above mixture of sodium oxide, silicon dioxide, iron oxide and dispersant in the water and mixed until the water vapor And mixed by stirring.
마지막으로, 상기 단계에서 수증기가 발생 되면 혼합된 물질에 포타슘 메틸 실리코네이트 3~9중량부를 넣고 1시간 30분 ~ 2시간 정도 가열 교반하면 최종적으로 혼합되는 물질이 투명해지며, 이때부터는 가열을 멈추고 혼합된 물질이 식을 때까지 교반하여 혼합한다.
