Description
본 발명은 칼슘염을 주재로 한 내외장용 건축재 및 그의 제조방법에 관한 것이다. 더 상세하게는 소석회를 물 및 첨가제를 가하여 고압, 성형한 다음, 이를 중탄산나트륨, 탄산나트륨, 2인산 나트륨, 3인산 나트륨, 불화나트륨, 유화나트륨, 암모늄의 인산염, 탄산염, 중탄산염, 황산염, 아황산염, 불화염ㅁ, 유화염 등으로 구성된 1종 이상의 염 수용액에 넣고 상온 내지 100℃의 온도 및 상압 내지 500kg/㎠의 범위의 압력에서 1시간 내지 수주일 방치시킴으로서 성형제[Ca(OH)2]를 칼슘의 무기염, 즉 탄산염, 인산염등으로 전환시켜 경도, 인장강도 및 내충격성이 우수한 건축재를 제조하는 것이다.The present invention relates to a building material for interior and exterior using calcium salt as a main ingredient and a manufacturing method thereof. More specifically, slaked lime is formed under high pressure by adding water and additives, and then sodium bicarbonate, sodium carbonate, sodium diphosphate, sodium triphosphate, sodium fluoride, sodium emulsion, ammonium phosphate, carbonate, bicarbonate, sulfate, sulfite, and fire The molding agent [Ca (OH) 2 ] is calcium-containing by placing it in at least one aqueous salt solution composed of a flame, an emulsion, and the like and leaving it for 1 hour to several weeks at a temperature ranging from room temperature to 100 ° C. and a pressure ranging from normal pressure to 500 kg / cm 2. It is to convert to inorganic salts of carbonate, phosphate, etc. to produce a building material excellent in hardness, tensile strength and impact resistance.
종래 건축자재로서는 인조대리석 즉, 시멘트 등에 대리석조각 등을 넣어 제조한 물품, 합성수지, 충전제 등을 혼합하여 응고시켜 인조대리석을 제조하는 방법(일본 특개소 49-12883호, 동 50-34345, 동 52-133316호, 일본 특허공고소 50-399094호, 동 51-23966호, 동 57-34087호, 동 57-47145호, 동 59-93467호 등)등이 알려져 있으나, 이들 인조대리석은 질감은 천연 대리석과 다르고, 내마모성, 내화성, 내수성, 내노화성이 떨어져 주로 건축물의 내장재로 이용되어 왔다.As a conventional building material, a method of manufacturing artificial marble by coagulating by mixing artificial marble, that is, a product made by putting marble pieces, etc. into cement, and coagulating it (Japanese Patent Laid-Open No. 49-12883, East 50-34345, East 52) -133316, Japanese Patent Publication No. 50-399094, 51-23966, 57-34087, 57-47145, 59-93467, etc.), but the artificial marble has a natural texture. It is different from marble, and has been used mainly as interior materials of buildings due to its low wear resistance, fire resistance, water resistance, and aging resistance.
또한, 소석회를 단독으로 고압 성형한 것은 인장강도, 경도가 약하고, 물에 용해되며, 물에 용해되며, 물레 용해될 때는 강한 알칼리성을 나타내어 건강 및 환경에 유해하다.In addition, the high-pressure molding of slaked lime alone has weak tensile strength and hardness, is soluble in water, is soluble in water, and exhibits strong alkalinity when dissolved in water, which is harmful to health and the environment.
본 발명자는 이러한 문제를 해결하기 위하여 소석회에 7% 물을 첨가하여 이를 고압으로 압축성형하고, 건조한 후, 이산화탄소 개스를 고온, 고압하에 주입 반응시켜 대리석을 제조하는 방법을 특허 받은 바 있다(참고 : 특허공고 90-1541호). 그러나 이러한 방법은 제조 코스트가 높고, 천연 대리석이 갖는 단점, 즉 중량이 크고, 단열성이 적기 때문에 이러한 문제를 해결하기 위하여 소석회를 중탄산 암모늄과 저온에서 배합한 후, 고압에서 성형하면 상기 방법보다 낮은 코스트로 대리석을 제조할 수 있음을 발견하고, 특허 출원한 바 있다(참조 : 특허출원 제91-18075회).In order to solve this problem, the present inventors have patented a method of preparing marble by adding 7% water to slaked lime and compressing it at high pressure, drying, and injecting and reacting carbon dioxide gas under high temperature and high pressure. Patent Publication No. 90-1541). However, since this method has a high manufacturing cost, a disadvantage of natural marble, that is, a large weight and low thermal insulation, to solve this problem, when calcined lime is mixed with ammonium bicarbonate at low temperature and then molded at high pressure, the cost is lower than the above method. Discovered that marble can be produced, and has applied for a patent (see Patent Application No. 91-18075).
본 발명자는 제물성을 검토한 바, 동물의 뼈는 인산칼슘이 주성분이고, 인산칼륨[Ca3[PO4)2] : 탄산칼륨(CaCO3)의 비가 10:1정도이며, 여기에 황산칼슘, 유화칼슘 등이 함유되어 있고, 이러한 동물뼈의 물성은 인장강도가 높고, 재료적 성질이 목재와 유사한 장점이 있다. 또한 바다의 조개류의 주성분은 탄산칼슘이며, 탄산칼슘 : 인산칼슘의 비가 10:1의 비로 구성되어 있으며, 기타 미량의 불화염, 황산염, 아연, 마그네슘의 염이 함유되어 있고 외관이 광택성이 있으며, 내약품성, 내수성이 탁월하다.The inventors of the present invention examined that the bone is composed of calcium phosphate as a main component, and the ratio of potassium phosphate [Ca 3 [PO 4 ) 2 : potassium carbonate (CaCO 3 ) is about 10: 1. , Calcium emulsion, etc. are contained, and the physical properties of these animal bones have high tensile strength and material properties similar to wood. In addition, the main component of the sea shellfish is calcium carbonate, and the ratio of calcium carbonate to calcium phosphate is 10: 1.It contains other trace fluoride salts, sulfates, zinc and magnesium salts and has a glossy appearance. Excellent chemical resistance and water resistance.
만일, 상기 2종 물질의 장점을 결합하면 경도, 인장강도, 내충격성 및 내약품성이 우수한 물질로 되며, 이를 건축재로 이용하면 새로운 소재로서 유용한 것임을 착안하여 소석회[Ca(OH)2]의 하이드록시기를 인산염, 탄산염, 불화염, 아황산염 등으로 전환시키면 표면이 미려하고도 전술한 특징을 갖는 건축재로를 얻을 수 있음을 발견하고 본 발명을 완성하게 되었다.If combined with the advantages of the two materials, the material is excellent in hardness, tensile strength, impact resistance and chemical resistance, hydroxy of calcined lime [Ca (OH) 2] by using it as a building material, considering that it is useful as a new material The present invention has been completed by discovering that converting a group into a phosphate, carbonate, fluoride, sulfite, etc. can provide a building material having a beautiful surface and having the aforementioned characteristics.
본 발명의 목적은 소석회를 탄산나트륨, 중탄산나트륨, 중탄산암모늄, 아황산암모늄, 탄산암모늄, 3인산암모늄, 3인산나트륨, 2인산암모늄, 황산아연, 황산알루미늄, 유화나트륨, 황산나트륨, 아황산나트륨으로부터 선택된 1종 이상과 반응시켜 얻은 이들의 칼슘염 및 그의 제조방법을 제공하는 것이다.An object of the present invention is one type of hydrated lime selected from sodium carbonate, sodium bicarbonate, ammonium bicarbonate, ammonium sulfite, ammonium carbonate, ammonium triphosphate, sodium triphosphate, ammonium diphosphate, zinc sulfate, aluminum sulfate, sodium sulfate, sodium sulfate, sodium sulfite It is to provide these calcium salts obtained by reacting with the above and a method for producing the same.
본 발명의 또다른 목적은 탄산칼슘:인산칼슘의 중량비가 10:1∼1:10의 비율로 조성된 복염상태의 건축재 및 그의 제조방법을 제공하는 것이다.It is still another object of the present invention to provide a double-stranded building material having a weight ratio of calcium carbonate to calcium phosphate in a ratio of 10: 1 to 1:10 and a method for producing the same.
본 발명은 또다른 목적은 소석회로부터 탄산칼슘과 인산칼슘을 필수성분으로 함유시키고, 황산칼슘, 유화칼슘 및 불화칼슘으로 이루어진 군에서 선택된 1종 이상을 함유하는 건축재 및 그의 제조방법에 관한 것이다.Another object of the present invention is to provide a building material containing calcium carbonate and calcium phosphate as essential ingredients from slaked lime, and containing at least one member selected from the group consisting of calcium sulfate, calcium emulsion and calcium fluoride, and a manufacturing method thereof.
이하 본 발명을 상세히 설명한다.Hereinafter, the present invention will be described in detail.
우선 소석회, 탄산칼슘과 혼합한 소석회 또는 무기재료(시멘트, 모래등)을 함유하는 소석회를 300kg∼2000kg/㎠의 압력으로 성형하고, 성형품을 건조 및 전처리하고, 탄산나트륨, 중탄산카트륨, 중탄산암모늄, 아황산암모늄, 탄산암모늄, 3인산암모늄, 3인산나트륨, 2인산나트륨, 2인산암모늄, 황산아연, 황산알루미늄, 황산마그네슘, 유화나트륨, 황산나트륨, 아황산나트륨으로 구성된 군에서 선택된 1종 이상의 화합물의 용액에 전술한 성형품을 넣고, 상온 내지 100℃의 온도, 상압 내지 500kg/㎠의 압력의 조건에서 1시간 내지 수주일 방치하여 성형품의 소석회를 칼슘의 탄산염, 인산염과 같은 무기염으로 전환시킨다. 여기서 반응시간이 짧으면 성형품의 표면 근처에서만 소석회의 하이드록시기가 반응하여 칼슘의 무기염으로 전환되나, 1주일 내지 수주일 반응시키면 소석회의 성형풍의 내부까지 반응하여 칼슘의 무기염으로 전환된다. 따라서 목적하는 바에 따라서 반응시간을 적절히 결정한다. 소재를 건축재로 사용하는 경우, 성형물의 내부까지 전부 반응시키는 것은 에너지 소비가 과대하고, 제조 코스트가 상승하므로 표면으로부터 0.2∼1.0cm 정도만 전환되도록 하기 위해서는 상압하에서 2∼3일간 반응시키는 것이 특히 바람직하다.First, hydrated lime, hydrated lime mixed with calcium carbonate, or hydrated lime containing inorganic materials (cement, sand, etc.) are molded at a pressure of 300 kg to 2000 kg / cm 2, the molded product is dried and pretreated, sodium carbonate, sodium bicarbonate, ammonium bicarbonate, To a solution of at least one compound selected from the group consisting of ammonium sulfite, ammonium carbonate, ammonium triphosphate, sodium triphosphate, sodium diphosphate, ammonium diphosphate, zinc sulfate, aluminum sulfate, magnesium sulfate, sodium emulsion, sodium sulfate, sodium sulfite The molded article described above is placed and left for 1 hour to several weeks under conditions of a temperature of from room temperature to 100 ° C. and a pressure of from 500 kg / cm 2 to convert the slaked lime of the molded product into inorganic salts such as calcium carbonate and phosphate. If the reaction time is short, the hydroxyl group of the slaked lime reacts only in the vicinity of the surface of the molded product, and is converted into the inorganic salt of calcium. However, if the reaction is carried out for one week to several weeks, it is reacted to the inside of the shaped wind of the slaked lime and converted to the inorganic salt of calcium. Therefore, the reaction time is appropriately determined as desired. In the case of using the material as a building material, it is particularly preferable that the entire reaction to the inside of the molding is excessively consumed in energy, and the manufacturing cost is increased, so that the reaction is performed at normal pressure for 2 to 3 days in order to convert only 0.2 to 1.0 cm from the surface. .
