Description

무독성 접착성분을 포함하는 실내건축용 견운모 마감재 조성물{Sericite Finishing Material Composition for Interior Construction Containing Non-toxic Adhesive Component}Technical Field [0001] The present invention relates to a sericite finishing material composition for interior construction including a non-toxic adhesive component,

본 발명은 견운모 분말과 접착제 성분으로 구성된 실내건축용 마감재 조성물에 관한 것으로서, 견운모 분말을 피접착물에 접착하는 접착제 성분이 주변환경에 유해한 성분을 발산하는 유기물을 포함하지 않으면서 견운모 분말을 충분한 접착력으로 피접착물에 접착되도록 하는 마감재 조성물에 관한 것이다.The present invention relates to an interior finishing composition for building construction comprising a sericite powder and an adhesive component, wherein an adhesive component for adhering a sericite powder to an adherend does not contain an organic matter that emits a harmful component to the surrounding environment, And to adhere to the complex.

건축용 마감재는 일반적으로 각종 건축자재의 마감을 위해 사용하는 재료를 지칭하는 것으로서, 이러한 마감재는 통상적으로 각종 건축재료 분말과 이를 피접착물에 접착시키기 위한 접착제 조성물을 포함하여 구성된다.Background of the Invention Architectural finishing materials generally refer to materials used for finishing various building materials. Such finishing materials usually comprise various building material powders and an adhesive composition for adhering the same to the adherend.

최근의 건축용 마감재는 내산성, 내마모성, 내구성, 내열성, 내부식성, 방음, 단열 등의 고유한 기능뿐만 아니라, 웰빙시대에 적합하도록 외적 미감, 항균, 탈취, 원적외선 방사, 음이온 발생 등과 같은 새로운 친환경적 기능을 가진 마감재로 진화하고 있다.Recent architectural finishing materials have not only unique functions such as acid resistance, abrasion resistance, durability, heat resistance, corrosion resistance, soundproofing and insulation but also provide new eco-friendly functions such as external aesthetics, antibacterial, deodorization, It is evolving into a solid finish.

마감재에 이러한 친환경적 기능을 부여하기 위하여 새로운 종류의 건축재료 분말과 이를 피접착물에 접착시키는 접착제에 대한 개발이 이루어지고 있으며, 특히 환경에 유해한 성분이 함유된 접착제 성분을 환경 친화적인 성분으로 대체할 수 있도록 하는데 관심이 집중되고 있다.In order to provide these environmentally friendly functions to the finishing materials, a new kind of building material powder and an adhesive for bonding it to the adherend are being developed. In particular, an adhesive component containing an environmentally harmful component can be replaced with an environmentally friendly ingredient There is a growing interest.

접착제는 일상생활에 있어서 없어서는 안 될 정도로 다양한 분야에서 생활에 밀접하게 사용되고 있고, 특히 근래에 들어 주거환경에 대한 관심이 높아지면서 디자인적인 요소를 중요하게 여기고 이러한 욕구를 충족시키기 위하여 고급인테리어 자재를 2차 마감재로 사용하는데, 이때 2차 마감재 등을 고정하는 가장 널리 알려지고 보편적인 수단이 접착제를 이용하는 방법이다.Adhesives have been used extensively in everyday life in various areas of life. Especially in recent years, interest in the residential environment has become increasingly important. In order to satisfy these needs, Used as a car finish, the most widely known and common means of securing secondary finishes, etc., is the use of adhesives.

대표적인 건축용 접착제로서 주로 목재에 사용되는 에폭시계 접착제와 타일에 사용되는 수성 아크릴계 접착제가 있는데, 에폭시계 접착제는 접착력이 강하여 냉·난방에 의한 목재의 수축팽창을 최소화시키는 장점이 있는 반면에 가사시간(可使時間)이 짧고 초기접착력이 약하여 시공이 불편한 단점이 있다.Typical architectural adhesives include epoxy-based adhesives used mainly in wood and water-based acrylic adhesives used in tiles. Epoxy adhesives have the advantage of minimizing shrinkage and expansion of wood caused by heating and cooling, And the initial adhesive force is low, which is disadvantageous in construction.

수성 아크릴계 접착제는 가사시간이 충분히 길고 초기 접착력이 강하여 시공이 용이하나, 접착력이 약하여 환경온도변화에 따른 타일의 수축팽창이 발생하고 온도, 습도 등 환경조건의 변화로 인하여 쉽게 변형되는 목질계 바닥재에는 적용이 어렵다.The water-based acrylic adhesive has a sufficiently long pot life and is easy to construct due to its strong initial adhesive force. However, the tile is shrunk and expanded due to the change of the environmental temperature due to the weak adhesive force and is easily deformed due to changes in environmental conditions such as temperature and humidity. It is difficult to apply.

또한, 종래에 사용되고 있는 대부분의 접착제는 유기용제를 사용하고 있는데, 이는 포름알데히드 등의 발암물질과 휘발성 유기화합물(VOCs) 등의 인체 유해물질을 방출하여 새집증후군, 피부질환, 두통, 안구질환, 기관지염 등과 같은 질병을 유발함으로써 인체에 악영향을 끼치는 문제가 있다.Most conventional adhesives use an organic solvent, which emits harmful substances such as formaldehyde and volatile organic compounds (VOCs) to prevent sick house syndrome, skin diseases, headache, eye diseases, Bronchial inflammation and the like, thereby causing adverse effects on the human body.

특히, 시공 후 시간이 경과함에 따라 휘발성이 사라진 후에는 접착력이 급격히 떨어져 부분적으로 외벽 부착자재(타일, 석고보드 등)가 떨어지고, 습도와 온도가 높은 장소에 사용되는 경우 접착제에서 곰팡이 균이 발생하는 단점이 있다.Particularly, when the volatility disappeared after the lapse of time after the application, the adhesive force is suddenly dropped to partially remove the adhesive material (tile, gypsum board, etc.), and when the adhesive is used in a place having high humidity and temperature, There are disadvantages.

건축공사시에는 주로 시멘트에 물을 혼합한 시멘트풀 또는 시멘트, 모래, 물을 적당량 혼합한 시멘트 모르타르를 접착제로 사용하여 왔다.Cement mortar mixed with cement water or cement, sand, and water mixed with water has been used as an adhesive agent in construction work.

그런데 상기와 같이 시멘트를 이용하는 경우에는 시멘트 작업 특성상 작업공정이 많이 복잡하고, 작업시 전문적인 숙련기술이 필요하므로 작업시간이 길어지는 것은 물론 시공비용이 많이 드는 결점이 있다.However, in the case of using cement as described above, the work process is complicated due to the characteristics of the cement work and the skilled worker skill is required in the work, so that the work time is long and the construction cost is high.

시멘트풀을 사용하는 경우 시간의 경과에 따라 시멘트풀이 단시간에 건조되기 때문에 자주 물을 가하여 혼련 후 사용하여야 하는 단점이 있으며, 또한 시멘트풀이 함유하고 있는 수분을 피접착물이 조기에 흡수함으로써 충분한 접착강도를 기대하기 어렵고, 피접착물의 규격이나 접착면이 고르지 못한 경우에는 시멘트풀을 도포하는 것만으로는 피접착물의 수평을 잡기 어렵다는 단점이 있다.In the case of using cement paste, cement paste is dried in a short time according to the elapse of time. Therefore, there is a disadvantage that water should be frequently added after kneading with water. Also, since the cement paste absorbs moisture containing cement paste early, It is difficult to expect, and when the size of the adherend or the bonding surface is uneven, it is difficult to level the adherend simply by applying the cement paste.

또한, 시멘트 모르타르를 사용하는 경우에는 피접착부분 사이의 간격이 모르타르로 메어짐으로써 공사 후 표면이 일치하지 않아 추후 마감 모르타르로 미장처리를 하여야 하는 등의 조적과정이 번잡하고, 시멘트 모르타르의 점력을 증가시켜 벽면에 잘 접착되도록 하기 위하여 수용성 분말 점력증진제를 모르타르에 첨가하여 사용하기도 하나 벽돌, 블록, 판재 및 석재 등을 조적할 때 시멘트를 제외한 접착제를 사용하는 것은 여러 가지 제약이 따른다.In addition, when cement mortar is used, the gap between the adhered portions is filled with mortar so that the surface does not coincide after the construction, so that the masonry process is required to finish with mortar after finishing. In order to improve the adhesion to the wall surface, a water-soluble powder viscosity enhancer may be added to the mortar. However, there are various limitations in using an adhesive other than cement when a brick, a block, a plate, and a stone are combined.

또한, 콘크리트의 점력증진제로서 에폭시계 또는 불포화 폴리에스테르계 접착제와 같은 유용성 접착제가 사용되고 있으나 이는 고가이고 화재시 발화하는 문제점이 있으며, 건축자재가 물에 젖어있을 때에는 사용이 불가능하기 때문에 보편적 사용에 한계가 있다.In addition, although an oil-soluble adhesive such as an epoxy or an unsaturated polyester adhesive is used as a pressure-increasing agent for concrete, it is expensive and has a problem of ignition in the case of fire. When the building material is wetted with water, .

상기와 같이 건축분야에서 사용되는 다양한 접착제들은 여러 문제점을 가지고 있으며 이러한 문제들을 해결하기 위하여 여러 방안들이 제안되어 있는데, 한국등록특허공보 제10-1044239호에는 우레탄 발포체 분말, 에멀젼 수지, 숯분말, 무기 충전제, 송진, 증점제로 구성되는 건축 자재용 접착제 조성물이 개시되어 있고 한국등록특허공보 제10-0591267에는 비스페놀 A형 에폭시 수지, 수산화 알루미늄 난연제, 적인, 황토분말 또는 맥반석분말, 참숯 분말, 송진으로 조성된 건축용 난연 접착제가 개시되어 있으며, 상기 접착제들은 숯 등을 접착제에 첨가하여 접착제 자체의 냄새 및 유해물질을 탈취하고 원적외선 방출, 음이온 방사 및 항균효과를 제공하여 쾌적한 실내환경을 구현하고자 하였다.As described above, various adhesives used in the field of construction have various problems.

또한, 한국등록특허공보 제10-733926호에는 플라보노이드계 화합물, 폴리페놀계 화합물, 스테로이드계 화합물 또는 이들의 혼합물을 포함하는 기능성 접착제가 제안되어, 접착제의 구성 성분들 중에서 일부를 식물 건조 분말 등으로 대체함으로써 각종 휘발성 유기화합물을 저감시키고 포름알데히드를 제거할 수 있도록 하였다.Korean Patent Registration No. 10-733926 discloses a functional adhesive comprising a flavonoid compound, a polyphenolic compound, a steroid compound, or a mixture thereof. Part of the components of the adhesive is dried to a plant powder or the like By replacing them, various volatile organic compounds can be reduced and formaldehyde can be removed.

또한, 한국등록특허공보 제10-1053081호에는 코펄수지(copal gum)와 세락 수지(shellac gum)의 천연 수지액, 견운모, 토르마린, 자수정, 맥반석, 벤토나이트, 탄산칼슘 및 활석의 기능성 광물 고형물, 첨가제 또는 보조제, 증점제, 흐름방지제를 포함하는 접착제 조성물에 관한 발명이 개시되어 있으며, 환경적으로 유용한 기능을 가지면서 기존 합성수지를 이용한 접착제를 대체할 수 있는 무공해 접착제를 제공한다.Korean Patent Registration No. 10-1053081 discloses a functional mineral solids of copal gum and shellac gum, a functional resin solids of sericite, tourmaline, amethyst, elvan, bentonite, calcium carbonate and talc, additives Or an auxiliary agent, a thickener, and an anti-flow agent, and provides a pollution-free adhesive having an environmentally useful function and capable of replacing an adhesive using a conventional synthetic resin.

When the additive capable of removing the adhesive component harmful to the human body is included, the manufacturing cost is increased and both the environment friendliness and the adhesiveness are both satisfied There is a disadvantage that it can not do.

본 발명이 해결하려는 과제는 견운모 분말과 이를 피접착물에 접착시키는 접착성분을 포함하는 실내건축용 마감재 조성물에서, 상기 접착성분이 환경에 유해한 유기물질을 포함하지 않으면서 우수한 접착력을 가지도록 하는 실내건축용 견운모 마감재 조성물을 제공하는 것이다.The problem to be solved by the present invention is to provide a finishing composition for interior architectural use, which comprises a sericite powder and an adhesive component for bonding the composition to an adherend, wherein the adhesive component comprises an organic material which is harmful to the environment, To provide a finish composition.

본 발명에 따른 실내건축용 견운모 마감재 조성물은 건축용 접착제의 재료로 통상 사용되는 탄산칼슘, 석회 등을 대체하여 해양수산폐기물인 굴 껍질을 재활용하므로 환경오염을 줄이고 자원을 절약할 수 있어서 환경친화적이고 또한 인체에 유해한 유기용제를 포함하지 않아서 인체친화적이며, 신속한 응결과 높은 압축강도 및 부착강도를 발현하고 소성수축균열이 억제되므로 실내건축용 마감재로서 유용하고 폭넓게 이용될 수 있다.The present invention relates to a composition for finishing a sericultural element for building construction, which can reduce environmental pollution and save resources by replacing calcium carbonate, lime and the like which are commonly used as building adhesive materials, thereby recycling oyster shells, Which is harmless to the human body and is friendly to the human body, exhibits rapid condensation, high compressive strength and adhesion strength and suppresses plastic shrinkage cracking, so that it is useful and widely used as a finish material for interior construction.

본 발명의 마감재 조성물은 견운모 분말 70~90 중량%, 탄산칼슘(CaCO3) 3~9 중량%, 석고(CaSO4·2H2O) 3~9 중량%, 수화알루미나(Al2O3·nH2O) 1~5 중량%, 실리카(SiO2) 1~5 중량%, 소성(燒成)한 굴 껍질(oystershell) 분말 1~5 중량%를 포함한다.The finishing composition of the present invention comprises 70 to 90 wt% of a sericite powder, 3 to 9 wt% of calcium carbonate (CaCO 3 ), 3 to 9 wt% of gypsum (CaSO 4 .2H 2 O), hydrated alumina (Al 2 O 3 .nH 2 O) comprises 1-5% by weight of silica (SiO 2) 1 to 5% by weight, the firing (燒成) oyster shell (oystershell) powder, 1-5% by weight.

견운모(sericite)는 층상구조의 수화된 알루미늄 규산염 광물군의 일종으로서, 원적외선 방사율, 탈취율, 항균 및 항곰팡이성, 음이온 방출, 방오, 대기정화 등의 기능이 우수한 광물이다.Sericite is a group of hydrated aluminum silicate minerals with a layered structure and is excellent in functions such as far infrared ray emissivity, deodorization rate, antimicrobial and antifungal property, anion release, antifouling and air purification.

견운모는 대략 이산화규소(SiO2) 65~80 %, 산화알루미늄(Al2O3) 10~20 %, 산화칼륨(K2O) 9~11 % 및 기타 물 분자로 이루어져 있으며, 칼륨원자를 정점으로 하여 이를 받치는 산소원자와 이를 기저로 한 알루미늄, 규소 및 기타 금속과 수소 등의 원자가 결합하여 극히 안정된 결정구조를 이루고, 이러한 기본 결정구조에서 산소 및 칼륨원자가 불규칙적으로 치환된 구조의 천연 무기재료이다.The sericite consists of approximately 65 to 80% of silicon dioxide (SiO 2 ), 10 to 20% of aluminum oxide (Al 2 O 3 ), 9 to 11% of potassium oxide (K 2 O) and other water molecules, , Which is a natural inorganic material having an extremely stable crystal structure in which oxygen atoms supporting it and atoms such as aluminum, silicon, and other metals and hydrogen based thereon form an irregularly substituted structure of oxygen and potassium atoms in the basic crystal structure .

견운모는 가소성(plasticity), 건조강도(drying strength), 생강도(green strength)가 높아서 요업분야에 주로 이용되며, 도료, 전기절연체, 활마재(滑摩材), 화장품 등 다양한 분야에 이용되어 왔으나 실내건축용 마감재의 재료로서는 많이 이용되지 못하였다.The sericite has high plasticity, drying strength and green strength and is used in various fields such as paints, electric insulators, lubricants and cosmetics. It has not been widely used as a material for interior finishing materials.

본 발명은 이러한 특성을 나타내는 견운모를 실내건축용 마감재로 사용함으로써 실내 주거공간을 환경 친화적인 분위기로 조성하고자 하는 것이다.The present invention aims to provide an indoor living space in an environmentally friendly atmosphere by using a sericite that exhibits such characteristics as a finishing material for indoor construction.

먼저, 견운모를 분쇄하여 분말화하는데, 견운모의 탈취, 항균, 음이온 방출, 대기정화 등의 기능을 극대화하기 위하여 견운모 분말의 전체 표면적을 최대화하는 것이 바람직하고, 이를 위하여 견운모를 지름 10~100 ㎛ 크기로 미세하게 분쇄하는 것이 바람직하다.In order to maximize the functions such as deodorization, antimicrobial, anion release and atmospheric purification of the sericite, it is preferable to maximize the total surface area of the sericite powder. For this purpose, the sericite has a diameter of 10 to 100 μm To be finely pulverized.

상기 마감재 조성물 중 견운모를 제외한 나머지 성분은 물과 혼합되어 견운모의 접착제로서 작용하는데, 상기 조성물이 물과 혼합되면 접착제로 작용하는 각 성분과 물이 에트링가이트(ettringite) 반응을 하여 고화됨으로써 견운모를 피접착물과 결합시키게 된다.When the composition is mixed with water, each component acting as an adhesive reacts with water to ettringite and solidifies to form a sericite. And is bonded to the target complex.

탄산칼슘은 자연계에서 존재하는 염 중에서 가장 많이 존재하고 있으며, 일반적으로 무색의 결정 또는 백색의 고체로서 비중이 2.93이고 825 ℃에서 분해되며, 순수한 물에는 용해하지 않으나 이산화탄소를 함유하는 물에는 용해하여 중탄산칼슘을 생성하고 탄산칼슘에 산을 작용시키면 이산화탄소를 발생하는데, 탄산칼슘은 값이 싸고 비중도 크지 않아 공업분야에 널리 사용된다.Calcium carbonate is the most abundant salt present in the natural world. It is generally a colorless crystal or a white solid. It has a specific gravity of 2.93 and decomposes at 825 ° C. It dissolves in water containing carbon dioxide but does not dissolve in pure water, Calcium is produced and carbon dioxide is generated by the action of acid on calcium carbonate. Calcium carbonate is widely used in industrial fields because it is cheap and has a low specific gravity.

본 발명에서 탄산칼슘은 충전재로서 작용하며, 마감재 조성물 중 3~9 중량%로 혼합되고 친수성이 높고 흡유성이 낮으며 균질성이 우수하다는 장점을 갖는다.In the present invention, calcium carbonate acts as a filler and is mixed with 3 to 9% by weight of the finishing material composition, has high hydrophilicity, low in absorbency, and excellent homogeneity.

상기 탄산칼슘은 넓은 입도 분포를 갖는 것이 바람직한데, 입도 분포가 넓을수록 마감재 조성물 중 접착제 성분이 물과 반응하여 고화된 고화체의 충전밀도가 높아지고 공극률이 낮아지므로 고화체의 강도를 향상시키고 균열 발생을 억제할 수 있다.The calcium carbonate preferably has a wide particle size distribution. As the particle size distribution becomes wider, the adhesive component in the finishing material composition reacts with water to increase the filling density of the solidified solidified material and to lower the porosity, thereby improving the strength of the solidified material and suppressing cracking can do.

상기 접착제 성분은 물과 혼합되어 일정한 유동성을 가지는 페이스트(paste) 형태로 견운모를 접착하게 되는데, 충전재로 작용하는 탄산칼슘 입자가 미세할수록 비표면적이 커지고 이러한 미세입자에 유동성을 부여하기 위하여 물은 입자표면을 둘러싸게 되고 또한 입자와 입자 사이의 공간을 채워야 하므로 소요되는 물의 양이 증가한다.The adhesive component is mixed with water to bond the sericite to a paste having a certain flowability. The finer the particles of the calcium carbonate serving as the filler, the larger the specific surface area. In order to impart fluidity to such fine particles, The amount of water consumed increases as the surface is surrounded and the space between the particles and the particles is filled.

접착제 성분은 고화될 때 물이 증발하면서 건조·고화되는데, 물의 양이 많아지면 건조시 수축이 커지게 되어 균열발생이 증가할 수 있으므로 가능한 한 물을 적게 사용하는 것이 바람직하며, 탄산칼슘 입자의 비표면적이 작을수록, 즉 입자가 클수록 입자의 유동성을 확보하기 위해 소요되는 물의 양이 줄어서 고화체의 균열 발생을 억제할 수 있다.The adhesive component is dried and solidified while the water evaporates when it is solidified. When the amount of water is increased, the shrinkage upon drying becomes larger and the occurrence of cracks may increase. Therefore, it is preferable to use as little water as possible. The smaller the surface area, that is, the larger the particle size, the smaller the amount of water required to secure the fluidity of the particles, and the cracking of the solidified body can be suppressed.

탄산칼슘은 입도와 제조공정에 따라서 중질 탄산칼슘(ground calcium carbonate)과 경질 탄산칼슘(precipitated calcium carbonate)으로 구분될 수 있으며, 중질 탄산칼슘은 석회석을 물리적으로 분쇄, 분급하여 제조되고, 경질 탄산칼슘은 석회유(石灰乳)에 이산화탄소를 불어넣어 생기는 침전을 여과·건조·미세분쇄하는 화학적 방법으로 제조된다.Calcium carbonate can be classified into ground calcium carbonate and precipitated calcium carbonate depending on the particle size and the manufacturing process. Heavy calcium carbonate is produced by physically pulverizing and classifying limestone, and calcium carbonate Is produced by a chemical method of filtering, drying and finely grinding precipitates formed by blowing carbon dioxide into lime milk.

중질 탄산칼슘의 입자크기는 명확히 정의되어 있지 않으나 대략 지름이 1 ㎛ 이상을 가리키고 1~45 ㎛ 정도이며, 경질 탄산칼슘의 입자크기는 1 ㎛ 미만으로서, 중질 탄산칼슘은 경질 탄산칼슘에 비해 입자가 크고 비표면적이 작으며 입도 분포가 넓으므로, 고화체의 균열 억제를 위하여 중질 탄산칼슘을 사용하는 것이 바람직하다.The particle size of the heavy calcium carbonate is not clearly defined, but the particle size of the hard calcium carbonate is less than 1 占 퐉, and the diameter of the heavy calcium carbonate is about 1 占 퐉 or more and about 1 to 45 占 퐉. It is preferable to use heavy calcium carbonate in order to suppress the cracking of the solidified body because the large specific surface area is small and the particle size distribution is wide.

석고는 매우 부드러운 황산염 광물로서 능판상(菱板狀) 또는 주상 결정을 이루는데, 견운모 마감재의 초기 접착성 확보 및 강도발현에 주요한 역할을 수행한다.Gypsum is a very soft sulphate mineral which forms rhomboid or columnar crystals and plays a major role in ensuring initial adhesion and strength development of the sericite finish.

석고는 본 발명의 접착제 성분이 물과 접촉한 이후 수 시간 동안 유동성을 유지시켜주고 각 접착제 성분 간 또는 접착제 성분과 견운모 분말을 입체적으로 연결하는데 기여한다.The gypsum maintains fluidity for several hours after the adhesive component of the present invention has been in contact with water and contributes to the three-dimensionally connecting between the adhesive components or between the adhesive component and the sericite powder.

석고는 마감 조성물 중 3~9 중량%로 혼합되며, 3 중량% 미만이면 접착 초기에 에트링가이트의 생성이 작아져 초기강도가 저하되고 수축이 증가하는 문제가 있으며, 9 중량%를 초과하면 시공성이 저하될 뿐만 아니라 에트링가이트가 과다하게 생성되어 팽창에 의해 접착부위의 균열이 발생하여 접착강도가 저하되는 문제가 있다.If the amount of the gypsum is less than 3% by weight, the generation of ettringite tends to be reduced at the initial stage of the adhesion, thereby lowering the initial strength and increasing shrinkage. When the amount of the gypsum exceeds 9% by weight, There is a problem that the etch ring is excessively generated and the bonding portion is cracked due to expansion, resulting in deterioration of the bonding strength.

수화알루미나는 제조법에 따라 결정질 또는 젤 형태를 이루고 있으며, 마감재 조성물의 난연성과 안정성을 향상시키는 기능을 수행한다.The hydrated alumina has a crystalline or gel-like form according to the production method, and performs the function of improving the flame retardancy and stability of the finishing composition.

굴 껍질은 탄산칼슘이 주성분을 이루고 있고 이를 소성하면 산화칼슘(CaO)이나 수산화칼슘{Ca(OH)2}이 생성되며, 산화칼슘을 물과 작용시키면 발열하면서 수산화칼슘이 생성된다.Calcium carbonate (CaO) or calcium hydroxide {Ca (OH) 2} is formed when the oyster shell is composed mainly of calcium carbonate. When calcium oxide is reacted with water, calcium hydroxide is generated by heating.

수산화칼슘은 500 ℃이상의 고온에서의 내화성과 물 또는 특정 산에 대한 열화를 일으켜 접착력을 저하시키는 문제가 발생하는데, 수화알루미나는 수산화칼슘과 결합하여 수화칼슘 알루미네이트 또는 실리코 알루미네이트, 하이드로가네트(hydrogarnet)를 형성함으로써 마감재의 접착부위에는 수산화칼슘이 존재하지 않게 된다.The calcium hydroxide has a problem of refracting at a high temperature of 500 ° C or higher and deteriorating the water or a specific acid to lower the adhesive strength. The hydrated alumina combines with calcium hydroxide to form hydrated calcium aluminate or silicoaluminate, hydrogarnet So that calcium hydroxide is not present at the bonding site of the finish material.

수화알루미나는 마감재 조성물 중 1~5 중량%로 혼합되는데, 상기의 양이면 수산화칼슘과 결합하기에 충분한 분량이고, 또한 1 중량% 미만이면 난연성과 안정성이 불충분하고 5 중량%를 초과하면 마감재 조성물의 점도가 상승하므로 바람직하지 못하다.The amount of the hydrated alumina is 1 to 5% by weight of the finishing composition. If the content is less than 1% by weight, the flame retardancy and stability are insufficient. If the amount exceeds 5% by weight, Which is undesirable.

실리카는 이산화규소 또는 규산 무수물이라고도 하며 지각 중에 가장 많이 존재하는 성분으로서, 거의 모든 토사 암석 속에 다른 성분과 결합한 규산염 광물로 존재하는 외에, 순수한 상태에서는 규사(珪砂), 규석(珪石)으로 존재한다.Silica is also known as silicon dioxide or silicic anhydride, and is the most abundant component in the crust. It is present as silicate minerals bound to other elements in almost all the earth rocks, and in pure state as silica sand and silica.

실리카는 물에 이온 상태, 콜로이드 상태로 함유되어 있으며, 실리카 용액을 급냉하면 쉽게 유리상태로 전환하여 석영 유리가 되며, 석영 유리는 고내열성(高耐熱性)이어서 열팽창률이 대단히 작고 열충격에 강할 뿐만 아니라 내약품성(耐藥品性)이 우수하다.Silica is contained in water in an ionic state and in a colloid state. Quartz glass is easily converted into a glass state by quenching the silica solution. Quartz glass has a high heat resistance (very high heat resistance) and has a very low coefficient of thermal expansion and is resistant to thermal shock But it has excellent chemical resistance.

본 발명의 마감재 조성물을 물과 혼합하면 실리카가 물에 분산되면서 졸(sol) 형태로 변하고 상기 졸은 접착제 조성물의 내구성, 내식성을 증가시키며, 구상(球狀)의 실리카 입자가 굴 껍질 입자표면에 부착되어 비표면적을 향상시킴으로써 열충격을 완화하고 균열의 방지에도 효과가 있다.When the finishing composition of the present invention is mixed with water, the silica is dispersed in water to form a sol. The sol increases the durability and corrosion resistance of the adhesive composition, and spherical silica particles are dispersed in the surface of oyster shell particles Thereby improving the specific surface area, thereby alleviating thermal shock and preventing cracking.

실리카가 존재하는 자연상태의 규산염 광물은 네소 규산염 광물(nesosilicate minerals), 소로 규산염 광물(sorosilicate minerals), 사이클로 규산염 광물(cyclosilicate minerals), 이노 규산염 광물(inosilicate minerals), 필로 규산염 광물(phylosilicate minerals), 텍토 규산염 광물(tectosilicate minerals)로 분류할 수 있으며, 이들 규산염 광물을 미세 분쇄하여 본 발명의 마감재 조성물에 실리카 성분으로 첨가할 수 있다.Natural state silicate minerals in which silica is present include nososilicate minerals, sorosilicate minerals, cyclosilicate minerals, inosilicate minerals, phylosilicate minerals, Tectosilicate minerals. These silicate minerals can be finely pulverized and added as a silica component to the finishing composition of the present invention.

이들 규산염 광물 중 이노 규산염 광물은 SiO4 사면체가 직선 모양으로 결합되어 있는 섬유상 모양의 광물로서 휘석, 각섬석, 연옥 등이 여기에 해당하고, 텍토 규산염 광물은 SiO4 사면체가 그물눈 모양으로 결합되어 있는 그물눈 구조형 광물로서 정장석, 준장석, 비석(沸石), 석영, 옥수(玉髓), 단백석, 앨바이트(albite), 소달라이트(sodalite), 휼란다이트(heulandite), 스틸바이트(stilbite) 등이 여기에 해당하는데, 상기 이노 규산염 광물과 텍토 규산염 광물은 섬유상의 잔섬유를 많이 가지고 있어서 이들 잔섬유에 의해 본 발명의 마감재 조성물의 상호 간 부착력이 증가하여 마감재 조성물이 접착·경화된 부위의 강도가 증가한다.Among these silicate minerals, inosilicate minerals are fibrous minerals in which a SiO 4 tetrahedron is linearly bonded, such as pyroxene, amphibole, and nephrite, and tectosilicate minerals are meshes in which a tetrahedron of SiO 4 is bonded in a net shape Quartz, quarzite, zeolite, quartz, agate, opite, albite, sodalite, heulandite, stilbite, etc., are available as structural minerals here , The inosilicate mineral and the tectosilicate mineral have a large amount of residual fiber in the fiber so that the mutual adhesion between the finishing material composition of the present invention is increased by these residual fibers to increase the strength of the portion where the finishing material composition is bonded and cured do.

실리카는 마감재 조성물 중 1~5 중량%로 혼합되는데, 1 중량% 미만이면 굴 껍질의 산화칼슘과의 결합상을 형성하는 양이 너무 적어서 마감재 조성물의 결합력이 낮아지고 5 중량%를 초과하면 접착·경화된 부위에 여분의 실리카가 너무 많이 잔존하여 오히려 결합력을 떨어뜨린다.Silica is mixed with 1 to 5 wt% of the finishing composition. When the amount of the silica is less than 1 wt%, the amount of the oily shell to form a binding phase with the calcium oxide is too small to lower the binding force of the finishing composition. Too much silica remains on the cured site, which reduces the bonding force.

굴 껍질은 해양수산폐기물인 패류양식업의 부산물로서, 주성분은 방해석구조의 탄산칼슘이고 이를 고온에서 연소시키면 탈탄산되어 산화칼슘으로 전환되는데, 산화칼슘은 상기 석고, 알루미나 등과 함께 물과 반응하여 고형화됨으로써 견운모를 피접착물과 결합시키게 된다.Oyster shell is a by-product of shellfish aquaculture, which is marine aquatic wastes. The main component is calcium carbonate of calcite structure. When it is burned at high temperature, it is decarbonated and converted into calcium oxide. Calcium oxide is solidified by reacting with gypsum, The sericite is combined with the adherend.

굴 껍질에는 탄산칼슘 외에도 인(phosphorus) 성분이 함유되어 있어서 물과의 반응시 인산칼슘을 생성하여 강도가 향상되며, 천연의 다공성 무기물로서 열충격에 의한 수축·팽창에 매우 안정하여 접착부위의 균열을 억제하는 장점을 지닌다.In addition to calcium carbonate, phosphorus is contained in the oyster shells. It reacts with water to produce calcium phosphate, which improves the strength. It is a natural porous inorganic material that is very stable in shrinkage and expansion due to thermal shock, .

본 발명에 사용되는 굴 껍질은 굴 껍질을 세척하여 염분, 악취, 불순물 등을 제거하고 이를 고온에서 가열한 다음 200 메쉬(mesh) 이상으로 미분쇄하여 얻은 분말형태로 사용되며, 상기 연소는 탄산칼슘이 탈탄산하여 산화칼슘으로 충분히 전환될 수 있도록 900 ℃ 이상의 온도에서 2 시간 이상 가열하는 것이 바람직하고, 900~1200 ℃에서 2~3 시간 가열하는 것이 더욱 바람직하다.The oyster shell used in the present invention is used in the form of a powder obtained by washing oyster shells to remove salts, odors, impurities and the like and then heating it at a high temperature and finely grinding it to a size of 200 mesh or more, It is preferable to heat at a temperature of 900 DEG C or more for 2 hours or more so that it can be converted into calcium oxide by decarbonation, and it is more preferable to heat at 900 to 1200 DEG C for 2 to 3 hours.

일반 콘크리트를 구성하는 포틀랜드 시멘트는 수산화칼슘이 고온에서 탈수되면서 붕괴의 원인이 되어 내화성이 낮으며, 또한 산류(酸類), 염류(鹽類), 아황산가스 등의 화학물질로 인해 열화되고 침식되기 쉬워서 건축구조물이 조기에 열화되는 문제가 있다.Portland cement, which constitutes ordinary concrete, is low in fire resistance due to dehydration of calcium hydroxide due to dehydration at high temperatures, and is easily degraded and eroded due to chemicals such as acids, salts, and sulfur dioxide, There is a problem that the structure deteriorates prematurely.

이러한 콘크리트의 산에 의한 열화는 수산화칼슘이 산에 의해 중화되어 분해하는 데 따른 것인데, 이는 수산화칼슘이 시멘트 수화물과 산의 중화반응으로 생기는 생성물의 용해도를 높이기 때문이다.The degradation of these concrete by acid is due to neutralization and decomposition of calcium hydroxide by acid, because the calcium hydroxide enhances the solubility of the product resulting from the neutralization reaction of cement hydrate with acid.

굴 껍질을 가열하면 굴 껍질의 탄산칼슘이 가열온도에 따라 산화칼슘이나 수산화칼슘으로 전환되는데, 본 발명에서와 같이 900 ℃ 이상에서 2 시간 이상 가열하면 탄산칼슘이 전량 산화칼슘으로 전환되어 에트링가이트 반응에 참여하므로 콘크리트 건축재의 접착제로 사용하여도 건축재의 열화를 방지할 수 있다.When the oyster shell is heated, the calcium carbonate of the oyster shell is converted into calcium oxide or calcium hydroxide according to the heating temperature. When the oyster shell is heated at 900 DEG C or more for 2 hours or more as in the present invention, calcium carbonate is converted into calcium oxide It is possible to prevent the deterioration of the construction material even if it is used as an adhesive for a concrete building material.

또한, 굴 껍질로부터 생성된 산화칼슘은 실리카, 알루미나와 함께 수화반응을 하여 규산칼슘계 건축자재의 합성에 사용될 수 있어서, 본 발명의 마감재 조성물을 규산칼슘계 건축자재의 접착용도로 사용할 경우 건축자재를 동질의 성분으로 접착하므로 접착부위의 균열방지에 효과적이다.Calcium oxide generated from oyster shells can be used for synthesis of calcium silicate-based building materials by performing hydration reaction with silica and alumina. Therefore, when the finishing material composition of the present invention is used for bonding calcium silicate-based building materials, As a homogeneous component, so that it is effective in preventing cracks at the bonding site.

굴 껍질의 단면을 보면 치밀한 판상구조인 시트층(sheet layer)과 비표면적이 큰 다공성 구조의 벌키층(bulky layer)으로 구성되어 화학조성과 구조에서 서로 차이가 있는데, 상기 층들 중 시트층은 가열하지 않고 그대로 분쇄하고 벌키층은 가열하여 분쇄하는 것이 바람직하다.The section of the oyster shell is composed of a sheet layer, which is a dense plate structure, and a bulky layer, which has a porous structure with a large specific surface area. There are differences in chemical composition and structure, It is preferable that the pulverization is carried out without heating and the pulverizer layer is heated and pulverized.

탈탄산되지 않은 시트층은 잔존하는 실리카와 함께 경화체로 남아 골재역할을 수행하고 또한 조성물 성분인 탄산칼슘의 사용량을 줄일 수 있으며, 가열에 의해 탈탄산된 벌키층은 실리카와 반응함으로써 토버머라이트(tobermorite) 또는 제노트라이트(xonotlite)와 같은 결합상을 형성하여 마감재 조성물에 결합력을 부여한다.The non-decarbonated sheet layer remains as a cured product together with the remaining silica to serve as an aggregate and can also reduce the amount of calcium carbonate used as a component of the composition, and the decarbonated layer is heated by heating to react with silica, such as tobermorite or xonotlite, to provide a bonding force to the finish composition.

이와 같이 다공성 구조의 벌키층을 가열하여 산화칼슘으로 전환시켜 수화반응에 참여시키고 치밀한 구조의 시트층은 골재역할을 수행하도록 함으로써, 고화체의 거대기공이 적고 미세기공이 많아져 구조가 치밀해지며, 이에 따라 강도가 향상되고 길이변화율이 억제되어 수축균열이 방지되는 효과를 얻을 수 있다.In this way, the porous structure layer is heated to convert it to calcium oxide to participate in the hydration reaction, and the dense structure sheet layer serves as an aggregate. Thus, the solid pores are small and the fine pores are small, As a result, the strength is improved and the rate of change in length is suppressed, whereby shrinkage cracking can be prevented.

상기 가열하여 분쇄된 굴 껍질 분말은 알루미나 및 석고 등과 함께 물과 섞이면 하기의 반응식과 같이 에트링가이트 반응하여 고형화되며, 수화에 의해 에트링가이트라는 침상 결정이 생성되어 공극이 감소하기 때문에 접착부위에서 건조 수축에 의한 균열이 감소함과 동시에 장기 강도향상 및 방수 증진효과를 얻을 수 있다.
When the oily shell powder is mixed with water together with alumina, gypsum and the like, the heated and pulverized oyster shell powder is solidified by the reaction of Ettingkite as shown in the following reaction formula, and acicular crystals such as ettringite are formed by hydration, Cracks due to shrinkage can be reduced and long-term strength improvement and waterproofing enhancement effect can be obtained.

3CaO+Al2O3+3CaSO4+32H2O → 3CaO·Al2O3·3CaSO4·32H2O 3CaO + Al 2 O 3 + 3CaSO 4 + 32H 2 O → 3CaO · Al 2 O 3 · 3CaSO 4 · 32H 2 O

상기와 같이 제조된 마감재 조성물은 건축용 접착제의 재료로 통상 사용되는 탄산칼슘, 석회 등을 대체하여 해양수산폐기물인 굴 껍질을 재활용하므로 환경오염을 줄이고 자원을 절약할 수 있어서 환경친화적이고 인체에 유해한 유기용제를 포함하지 않아서 인체친화적이며, 통상의 포틀랜드 시멘트 경화체에 비하여 거대기공이 적고 미세기공이 많아서 경화체의 구조가 치밀하여 강도가 높으며, 내산성 및 내화성 등의 각종 물성이 우수하다.
The finishing composition thus prepared recycles oyster shells, which are marine fish wastes, in place of calcium carbonate and lime commonly used as building adhesive materials, thereby reducing environmental pollution and saving resources, thereby being environmentally friendly and harmful to the human body. It does not contain solvents and is human-friendly.

상기 표 2에 나타난 바와 같이, 응결시간은 전체적으로 실시예가 초결 및 종결 시간이 짧고 비교예가 길며, 특히 경질 탄산칼슘과 가열하지 않은 굴 껍질을 사용한 비교예 2의 응결시간이 가장 긴 것을 알 수 있다.As shown in Table 2 above, it can be seen that the coagulation time of Comparative Example 2 using the hard calcium carbonate and the unheated oyster shell is the longest, in particular, the coagulation time is short in the embodiments of the present invention.

압축강도와 부착강도 또한 실시예가 비교예보다 우수한 결과를 나타내었는데, 굴 껍질의 시트층과 벌키층을 분리한 후 벌키층만을 가열하여 시트층과 합한 실시예 5의 강도가 가장 우수하고 굴 껍질을 사용하지 않은 비교예 1 및 굴 껍질을 가열하지 않은 비교예 2가 낮게 측정된 결과로부터 굴 껍질을 고온으로 가열하여 마감재 조성물에 혼합하는 것이 강도 향상에 바람직하고 굴 껍질 중 벌키층만을 분리하여 가열하는 것이 고화체의 구조를 좀더 치밀하게 하여 강도 면에서 유리한 효과를 제공함을 알 수 있다.Compression strength and adhesion strength also showed better results than those of the comparative example, except that the oyster shell layer and the honeycomb layer were separated, and only the bulk layer was heated to obtain the most excellent strength in Example 5 combined with the sheet layer, It was found from the results that the unused Comparative Example 1 and the Comparative Example 2 in which the oyster shells were not heated were heated at a high temperature and the oyster shells were heated to a high temperature for mixing in the finishing composition to separate the oyster shell from the oyster shell, It is understood that the structure of the solid body is made more dense to provide a favorable effect in terms of strength.

길이변화율은 비교예가 비교적 크고 이에 따라 고형체에서 균열이 다수 발생함을 알 수 있다.
It can be seen that the rate of change in length is comparatively large, and thus a large number of cracks are generated in the solid body.

<시험예 2> 피부 첩포시험&Lt; Test Example 2 >

건선, 습진 등의 피부병변 보균자나 항히스타민제 복용자를 제외한 20 명의 피험자를 대상으로 haye's chamber를 이용한 피부 첩포 시험을 실시하였다.Twenty subjects, except those with skin lesions such as psoriasis, eczema, and those taking antihistamines, were subjected to a skin patch test using haye's chamber.

팔 안쪽 부위를 70 % 에탄올로 닦아내고 건조한 다음, 여기에 상기 시험예 1의 마감재 조성물과 물의 혼합물 각각을 chamber에 적하시킨 후 첩포하였다.The inside of the arm was wiped with 70% ethanol and dried. Then, each of the mixture of the finishing composition of Test Example 1 and water was dripped into a chamber, and then applied.

24 시간 경과 후 시험부위를 표시한 다음 첩포물을 제거하고 30 분, 24 시간, 48 시간 경과 후 시험부위를 관찰하여 국제접촉피부염연구회(International Contact Dermatitis Research Group : ICDRG)에서 제시하는 평가기준에 따라 피부자극지수를 판정하였다.After 24 hours, the test area was marked and the test piece was removed. After 30 minutes, 24 hours, and 48 hours, the test site was observed and evaluated according to the criteria given by the International Contact Dermatitis Research Group (ICDRG) The skin irritation index was determined.

판정 결과, 상기 실시예 1~5 및 비교예 1, 2의 마감재 조성물을 사용한 첩포시험 모두에서 무자극(피부자극지수 0.00)으로 판정되었으며, 이러한 결과로부터 본 발명의 마감재 조성물이 인체와 접촉하여도 피부에 자극을 주지 않음을 알 수 있다.
As a result of the determination, it was judged to be unstimulated (skin irritation index 0.00) in both of the pellet tests using the finishing composition of Examples 1 to 5 and the comparative examples 1 and 2. From these results, it was found that even when the finishing composition of the present invention was in contact with the human body It can be seen that the skin is not stimulated.
