오늘날 건축용 외장재나 내장재로 천연 대리석이 사용되고 있다. 그러나 천연대리석의 무분별한 채취로 자연환경 파괴 및 자원의 고갈 등 문제점이 발생하였고, 천연석의 색상 및 질감이 불규칙하여 건물 외장을 마감하였을 경우 외장이 고르지 못한 문제점이 발생해왔다.Today, natural marble is used for building exterior and interior materials. However, indiscriminate sampling of natural marble caused problems such as destruction of the natural environment and depletion of resources, and the exterior of the building was uneven because of the irregular color and texture of the natural stone.
최근에는 그러한 문제점을 해결하기 위한 방법으로 고압프레스 성형된 인조 대리석 판재가 제작되고 있다. 그러나 현재 생산되고 있는 인조 대리석 판재는 고가의 기계설비를 필요로 하고 제작 비용이 고가이므로 경제성이 떨어지며 1000톤 이상의 대형 압축프레스 장치를 이용하므로 각종 조형물 제작이 어려운 단점이 있다. Recently, a high-pressure press-molded artificial marble sheet has been produced as a method for solving such problems. However, currently produced artificial marble sheet material requires expensive mechanical equipment and manufacturing cost is expensive, so it is economically inferior and uses a large compression press device of more than 1000 tons, it is difficult to manufacture various sculptures.
또한, 보온성과 단열성, 내화성, 내마모성, 인장성의 향상을 위하여 섬유상의 석면을 사용하였으나 1970년대 이후 석면이 폐질환과 치명적인 폐암인 중피종(中皮腫)을 일으키는 것으로 알려지면서 사용이 중단되어 그 대체물질의 사용이 시급히 요구되고 있는 실정이다.In addition, fibrous asbestos was used to improve insulation, heat insulation, fire resistance, abrasion resistance, and tensile properties.However, asbestos became known to cause lung disease and mesothelioma, a deadly lung cancer since the 1970s, its use was discontinued. The use of is urgently required.
또한, 종래의 골재와 시멘트계 수경성 바인더를 혼합하고 경화시켜 제조하는 방법등에 의해 제조된 인조대리석의 강도는 300~400kg/cm2 로서 고강도 인조대리석을 제조할 수 없고, 수지 바인더의 취급상 어려움이 많았으며, 그 생산단가가 높다는 문제점이 있었다.In addition, the strength of the artificial marble prepared by the method of mixing and curing the aggregate and cement-based hydraulic binder of the prior art is 300 ~ 400kg / cm 2 It is not possible to manufacture high-strength artificial marble, there was a lot of difficulties in handling the resin binder There was a problem that the production cost is high.
이러한 문제점을 해결하기 위하여 본 발명은 석면을 대체할 수 있는 물질로서 규회석(CaSiO3)을 사용하여 인체에도 무해하도록 제작하여 소비자의 욕구를 충족시키고 대리석의 균열, 팽창, 변형을 최소화하며, 친환경적인 인조대리석 제조방법을 제공한다.In order to solve this problem, the present invention is manufactured to be harmless to the human body using wollastonite (CaSiO 3 ) as a material that can replace asbestos to meet the needs of consumers and minimize the cracking, expansion and deformation of the marble, It provides a method of manufacturing artificial marble.
또한,알루미나시멘트(Al2O3CA-50)에 천연돌가루를 혼합하였고, 수축률을 낮추기 위해 석고(CaSO4)를 첨가하였으며, 대량생산을 위하여 경화 촉진 응고제(Li2CO3)와 적정량의 물과 구체방수제(Na2O nSiO2 xH2O)를 첨가하여 초기응결 10~20분 압축강도에서 후기강도(28일)가 500kg/cm2 이상의 고강도 및 속경화성 시멘트 판재, 조형물을 제조하여 반영구적이고 균일한 색상의 제품을 생산하며 인체에도 무해하도록 제작하여 소비자의 욕구를 충족시키고, 친환경적 인조대리석을 제조하는데 그 목적이 있다.In addition, natural stone powder was mixed with the alumina cement (Al 2 O 3 CA-50), gypsum (CaSO 4 ) was added to reduce the shrinkage rate, and a hardening promoting coagulant (Li 2 CO 3 ) and an appropriate amount of mass were produced. Semi-permanent production of high strength and fast curing cement plates and sculptures with a late strength (28 days) of more than 500kg / cm 2 at initial condensation 10 ~ 20 min compressive strength by adding water and concrete waterproofing agent (Na 2 O nSiO 2 xH 2 O) Its purpose is to produce products of uniform color and to be harmless to the human body to meet consumer needs and to manufacture environmentally friendly artificial marble.
또한, 인조대리석 판재의 제조에 있어 종래의 고가 장비인 대형압축 프레스장치 없이 진동압축 성형방법을 사용함으로써 제조 비용을 절감할 수 있고, 혼합물을 형틀에 부어 양생시킨 후 가공할 수 있도록 하여 조형물 제작도 가능한 인조대리석 조형물 제조방법을 제공한다.In addition, in the production of artificial marble plate material by using the vibration compression molding method without a large compression press device, which is a conventional expensive equipment, it is possible to reduce the manufacturing cost, and to manufacture the molding by pouring the mixture into the mold and curing it It provides a method of manufacturing artificial marble sculptures possible.
본 발명은 초속경 알루미나시멘트(Al2O3CA-50)에 천연색상돌가루 등과 무기질 안료를 미량 혼합한 제품으로 균일한 색상과 각종 형태의 조형물을 제작하여 반영구적인 내·외장재를 개발하는데 본 발명의 목적이 있다.The present invention is to produce semi-permanent interior and exterior materials by producing a uniform color and various types of moldings with a product mixed with a trace amount of natural color stone powder and inorganic pigments in superhard alumina cement (Al 2 O 3 CA-50). There is an object of the invention.

종래의 대형압축 프레스장치를 사용하지 않고, 진동압축 성형방법으로 인조대리석 판재를 제조함으로써 제조비용을 절감할 수 있는 장점이 있다.Without using a conventional large-scale compression press apparatus, there is an advantage that can reduce the manufacturing cost by manufacturing the artificial marble plate by the vibration compression molding method.

본 발명자의 여러 가지 실험을 고강도 및 속경화성의 특성을 가지는 원료의 비율을 발견하였다는 점에 본 발명의 특징이 있다. 이하 그 조성비율을 검토한다.It is a feature of the present invention that various experiments of the present inventors found the proportion of raw materials having high strength and fast curing properties. The composition ratio is examined below.
본 발명에 사용되는 알루미나시멘트(Al2O3CA-50)의 주성분은 알루미나 ·생석회 CaO ·무수규산 등의 용융물(溶融物)이며, CaO ·Al2O3 및 5CaO ·3Al2O3이 주요 광물로서 포틀랜드시멘트에 비해서 알루미나 성분이 상당히 많다. 석회석과 보크사이트 또는 반토혈암(礬土頁岩) 등 알루미나 성분이 많은 점토류(粘土類)와 배합하여 1,500~1,600 ℃에서 용융한 다음 유출시켜서 냉각한 후 미세한 분말로 한 것이다. 내식성(耐蝕性) ·내화성 등도 포틀랜드시멘트 보다 우수하고 초속경 시멘트로 강도, 인장력이 우수하다.The main component of the alumina cement (Al 2 O 3 CA-50) used in the present invention is a melt such as alumina, quicklime CaO, silicic anhydride, CaO, Al 2 O 3 and 5CaO 3Al 2 O 3 As a mineral, there are considerably more alumina components than Portland cement. Alumina, limestone, bauxite or alumina shale, etc., is mixed with a lot of clay, and it is melted at 1,500 ~ 1,600 ℃ and then cooled to make fine powder. Corrosion resistance and fire resistance are also better than Portland cement, and super fast cement has excellent strength and tensile strength.
천연원석돌가루는 일반적으로 공지된 구성이므로 그 설명을 생략한다.Natural gemstone powder is a generally known configuration, so the description thereof is omitted.
본 발명은 알루미나시멘트(Al2O3CA-50) 100중량부 대비 천연원석돌가루 180~250중량부를 첨가하는 것을 특징으로 한다. 알루미나시멘트 100 중량부대비 알루미나시멘트와 천연원석돌가루가 총 280중량부 이하이면 시멘트로서 일정한 물 리적 강도를 나타낼 수 없기 때문이다.The present invention is characterized in that the addition of 180 to 250 parts by weight of natural gem stone powder compared to 100 parts by weight of alumina cement (Al 2 O 3 CA-50). This is because when the total amount of alumina cement and natural gem stone is less than 280 parts by weight based on 100 parts by weight of alumina cement, it is impossible to exhibit a constant physical strength as cement.
규회석(CaSiO3)은 고온에서 구워 제조된 광물질로서 시멘트 모래와 응결시 3~5mm의 길이, 0.1~0.5mm굵기의 제품이 상호 연결시켜 인장력 및 파손되는 것을 방지시켜 준다. 규회석은 석면만큼 보온성과 단열성, 내화성, 내마모성 등이 뛰어나면서 값이 저렴한 물질로서 석면의 장점 그대로 가지고 있고 발암 위험이 거의 없어 석면의 유일한 대체물질로 사용될 수 있다. 국제 암 연구기관(IARC)은 규회석이 석면(Asbestos)과 구조, 화학식, 결정상이 완전히 달라 ‘Group3(발암물질이 아님)’으로 분류하고 있으며 이밖에 석면 대체 물질로는 해포석이라는 광물도 있으나 해포석의 경우 단가가 너무 높고 공급이 어려운 단점이 있다. 본 발명은 무석면 인조대리석 판재로서 규회석 함유제품의 부스러기나 분진 등이 호흡기를 통해 흡입된다 해도 인체에 전혀 해가 되지 않는다는 점에 특징이 있다.Wollastonite (CaSiO 3 ) is a mineral produced by baking at high temperatures to prevent tensile strength and breakage by connecting cement sand with products of 3 ~ 5mm length and 0.1 ~ 0.5mm thickness when condensing. Wollastonite is an inexpensive material with excellent heat insulation, heat insulation, fire resistance, and abrasion resistance asbestos, and has the advantages of asbestos, and can be used as the only substitute for asbestos because it has little risk of carcinogenesis. The International Cancer Research Institute (IARC) classifies wollastonite as 'Group3' (not a carcinogen) because its structure, chemical formula and crystal phase are completely different from asbestos. In this case, the unit price is too high and the supply is difficult. The present invention is characterized in that as a non-asbestos artificial marble plate material, even if debris or dust of wollastonite-containing product is inhaled through the respirator, it is not harmful to the human body at all.
본 발명은 규회석(CaSiO3)을 10~50중량부로 첨가하는 것을 특징으로 한다. 규회석이 10중량부 이하인 경우에는 바람직한 휨 강도를 나타내지 못하여 50중량부 이상인 경우에는 휨 강도 등은 향상되나 인장강도, 압축강도 등이 저하되기 때문이다. The present invention is characterized by adding wollastonite (CaSiO 3 ) to 10 to 50 parts by weight. This is because when the wollastonite is 10 parts by weight or less, the desired flexural strength is not exhibited. When the wollastonite is 50 parts by weight or more, the flexural strength is improved, but the tensile strength, the compressive strength, and the like are lowered.
석고는 초속경으로 굳어 양생되는 10~20분 사이에 수축되어 균열 및 변형을 방지시켜 주는 역할을 한다. 석고(CaSO4)는 2~10중량부를 첨가하는 것을 특징으로 한다. 석고가 2중량부 이하이면 수축의 역할을 제대로 수행할 수 없고 10중량부 이상이면 경제성대비 효과가 미약하기 때문이다.Gypsum hardens with a supersonic mirror to shrink between 10-20 minutes of curing, preventing cracks and deformation. Gypsum (CaSO 4 ) is characterized in that adding 2 to 10 parts by weight. If the gypsum is less than 2 parts by weight can not perform the role of shrinkage properly, if more than 10 parts by weight of the economic contrast effect is weak.
경화촉진 응고제는 제품의 생산회수를 빠르게 하고 속 경화성을 확보하기 위하여 하절기 또는 동절기에 각각 다른 비율을 적용하여 사용한다. 경화 촉진 응고제(Li2CO3)는 0.01~0.1중량부를 첨가하는 것이 바람직하다. 0.01중량부 이하이면 경화촉진의 역할을 수행할 수 없고 0.1 이상이면 경제성대비 그 효과가 미약하기 때문이다.Hardening accelerator coagulation agents are used in different periods during the summer or winter to speed up the recovery of the product and to ensure fast curing.
