Description
본 발명은 다양한 바탕면에 접착이 가능하면서 경화전 압력에 대한 변형성이 뛰어나 시공 후 일정시간 동안 양각 또는 음각 형태의 성형도구를 이용해 다양한 무늬를 자유자재로 연출할 수 있는 무기질계 미장 조성물에 관한 것이다.The present invention relates to an inorganic cosmetic composition capable of being adhered to various base surfaces and having excellent deformability against pressure before curing, which can freely produce various patterns using a molding tool in the form of embossing or intaglio for a certain period of time after construction.
건축물의 벽면을 시멘트 모르타르로 미장할 때 건축공사표준시방서 15000“미장공사”에 따르면 조적 및 콘크리트 면에 초벌, 재벌, 정벌로 구분하여 18~24㎜의 두께로 2~3회 미장 작업을 해야 한다. 일반적으로 콘크리트 건축물이나 벽돌 등을 이용한 조적식 건축물의 내,외벽을 시멘트 모르타르로 미장할 때 미장 작업자가 한손으로 들고 다닐 수 있는 손잡이가 부착된 작은 판재로 된 모르타르 운반 판재 위에 소량의 시멘트 모르타르를 올려놓고 미장작업 위치로 직접 운반하여 흙손을 이용하여 미장작업을 수행하고 있다.When plastering the wall of a building with cement mortar, according to the Building Construction Standard Specification 15000 “Plastering Work,” it is necessary to classify the masonry and concrete surfaces into roughing, concreting, and consolidating, and plastering 2 to 3 times with a thickness of 18 to 24 mm. . In general, when plastering the inner and outer walls of a concrete building or a masonry building using bricks with cement mortar, a plasterer puts a small amount of cement mortar on top of a mortar carrying board made of a small plate with a handle that can be carried with one hand. It is placed and transported directly to the plastering location, and plastering is performed using a trowel.

한편, 통상적인 건물 외벽의 미장재는 시멘트, 물, 모래를 혼합하여 외벽 표면에 바르는 형태로 이루어져 있는데, 외관이 미려하지 못하여 별도의 패널을 부착하여야 하기 때문에 그에 따른 비용이 상승하는 문제가 있었다.On the other hand, conventional plastering materials for exterior walls of buildings consist of a mixture of cement, water, and sand that is applied to the surface of the exterior wall. However, since a separate panel must be attached because the appearance is not beautiful, there is a problem in that the cost increases accordingly.
이러한 비용상승의 이유로 미장재를 도포한 후 표면에 음각이나 양각 형태의 성형도구를 이용하여 밋밋한 표면에 무늬를 형성하는 경우도 있었으나 대부분 무늬가 유지되지 못하는 문제점이 있었다.For this reason, there were cases where a pattern was formed on a flat surface by using a molding tool in the form of an intaglio or emboss on the surface after applying the plastering material, but in most cases, there was a problem in that the pattern could not be maintained.
상기와 같은 문제점을 해결하기 위한 본 발명에 따른 무기질계 미장 조성물은 건물 외벽 등의 바탕면에 미장시 분말수지에 의해 다양한 바탕면에 미장이 가능함은 물론, 미장 후 성형도구를 이용한 무늬 형성시 무늬 형상이 그대로 유지되며, 반복적인 성형도구 사용시에도 무늬 형성이 가능하여 다양한 무늬와 모양을 연출할 수 있고, 더욱이, 성형도구 사용시 성형도구에 묻어나지 않게 되어 더욱 무늬를 유지할 수 있는 무기질계 미장 조성물을 제공하는데 그 목적이 있다.In order to solve the above problems, the inorganic plastering composition according to the present invention can be plastered on various base surfaces by powder resin when plastering on the base surface such as the outer wall of a building, and the pattern shape when forming patterns using molding tools after plastering It is maintained as it is, and it is possible to form patterns even when repeatedly using molding tools, so that various patterns and shapes can be produced, and moreover, when using molding tools, it is not smeared on molding tools to provide an inorganic cosmetic composition that can further maintain the pattern. It has a purpose.
본 발명은 건물 외벽 등의 바탕면에 미장시 분말수지에 의해 다양한 바탕면에 미장이 가능함은 물론, 미장 후 성형도구를 이용한 무늬 형성시 무늬 형상이 그대로 유지되며, 반복적인 성형도구 사용시에도 무늬 형성이 가능하여 다양한 무늬와 모양을 연출할 수 있고, 더욱이, 성형도구 사용시 성형도구에 묻어나지 않게 되어 더욱 무늬를 유지할 수 있는 유용한 발명이다.In the present invention, when plastering the background surface such as the outer wall of a building, it is possible to plaster various base surfaces by powder resin, and the pattern shape is maintained as it is when forming patterns using molding tools after plastering, and even when using molding tools repeatedly, patterns can be formed. It is possible to produce various patterns and shapes, and moreover, it is a useful invention that can maintain the pattern more because it is not smeared on the molding tool when using the molding tool.
이하에서는 본 발명의 구성에 대해 보다 구체적으로 살펴보도록 한다.Hereinafter, the configuration of the present invention will be described in more detail.
본 발명은 시멘트 35 ∼ 40중량%, 분말수지 0.3 ∼ 0.6중량%, 석고 0.8 ∼ 1.2중량%, 탄산칼슘 1 ∼ 4중량%, 경화촉진제 0.1 ∼ 0.2중량%, 개질제 0.01 ∼ 0.50중량%, 모래 55 ∼ 60중량%, 메틸세룰로오즈 0.2 ∼ 0.4중량%, 소포제 0.1 ∼ 0.2중량%로 이루어져 있다.In the present invention, 35 to 40% by weight of cement, 0.3 to 0.6% by weight of powdered resin, 0.8 to 1.2% by weight of gypsum, 1 to 4% by weight of calcium carbonate, 0.1 to 0.2% by weight of hardening accelerator, 0.01 to 0.50% by weight of modifier, 55% sand to 60% by weight, 0.2 to 0.4% by weight of methyl cellulose, and 0.1 to 0.2% by weight of an antifoaming agent.
우선, 시멘트는 1종 시멘트 단독일 수 있고, 1종 시멘트와 백시멘트를 혼합한 형태로도 이루어질 수 있다. First of all, the cement may be a single type 1 cement, or a mixture of type 1 cement and white cement.
이러한 시멘트는 임계치 미만으로 사용할 경우 초기 강도 저하 및 접착력 저하, 치점 균열이 발생하는 문제가 있고, 임계치를 초과할 경우 경화가 빨리 이루어지게 되고 수화열에 의한 균열 및 수축에 의한 균열이 발생할 수 있다.When these cements are used below the critical value, there are problems in that initial strength and adhesiveness decrease, and point cracks occur. When the critical value is exceeded, hardening occurs quickly, and cracks due to heat of hydration and cracks due to shrinkage may occur.
다음으로, 분말수지는 성형도구 사용시 형상을 유지시킴과 동시에 성형도구에 본 발명의 조성물이 묻어나는 현상을 방지하기 위해 포함된다.Next, the powdered resin is included to prevent the composition of the present invention from smearing on the molding tool while maintaining the shape when using the molding tool.
이러한, 분말수지는 에틸렌-비닐 아세테이트 공중합체 55 ∼80중량%, 이소부틸 메타크릴레이트 20 ∼ 45중량%로 이루어져 있다.This powdered resin is composed of 55 to 80% by weight of ethylene-vinyl acetate copolymer and 20 to 45% by weight of isobutyl methacrylate.
상기 에틸렌-비닐 아세테이트 공중합체는 아세테이트 비닐 단량체와 다산 비닐 폴리머 기반의 재분사성 폴리머 바인더인 에틸렌-비닐 아세테이트 공중합체로서 개선된 유동성, 작업성, 높은 최종 강도, 응집력, 접착력, 가소성, 유연성 및 내마모성을 제공하고, 수축 및 균열을 줄여주게 되어, 본 발명을 건물 외벽에 마감재로서 도포할 경우 높은 부착력을 형성함은 물론, 음각 또는 양각 형태로 이루어진 성형도구를 이용해 무늬 형성시에도 유연성이 부여되어 무늬로 음각 또는 양각의 표현이 가능하고, 더욱이, 무늬 성형 후에는 무늬를 그대로 유지하되 반복적인 무늬 형성시에도 무늬 형성이 가능하며, 양생에 의한 수축시에도 변형이 발생하지 않아 작업자가 형성한 무늬를 그대로 유지할 수 있는 효과를 얻을 수 있게 되며, 특히, 접착성이 우수하여 콘크리트 옹벽, 타일면, 석재면 등의 다양한 바탕면에서도 접착성이 우수하게 된다.The ethylene-vinyl acetate copolymer is an ethylene-vinyl acetate copolymer, which is a re-dispersible polymer binder based on acetate vinyl monomer and polyvinyl polymer, and has improved fluidity, workability, high final strength, cohesion, adhesion, plasticity, flexibility and wear resistance. When the present invention is applied as a finishing material to the outer wall of a building, it forms high adhesive strength, and flexibility is imparted even when forming a pattern using a molding tool in the form of an intaglio or embossment to form a pattern. It is possible to express intaglio or relief, and moreover, the pattern is maintained after pattern molding, but it is possible to form a pattern even when repeatedly forming a pattern, and even when shrinking by curing, deformation does not occur, so the pattern formed by the operator remains intact. It is possible to obtain the effect that can be maintained, and in particular, the adhesiveness is excellent, so that the adhesiveness is excellent even on various base surfaces such as concrete retaining walls, tile surfaces, and stone surfaces.
이러한 에틸렌-비닐 아세테이트 공중합체는 임계치 미만으로 혼합하게 되면 부착강도가 미약하고, 수축시 변형 발생으로 인해 성형도구 사용시 형상유지가 어렵게 되고, 임계치를 초과할 경우에는 더 이상의 증진된 부착력을 발휘하기 어렵다.When these ethylene-vinyl acetate copolymers are mixed below the critical value, the adhesive strength is weak, and deformation occurs during shrinkage, making it difficult to maintain the shape when using a molding tool. .
또한, 이소부틸 메타크릴레이트는 성분들 간의 부착성을 향상시키고, 건조성, 내후성이 우수한 성분으로, 임계치 미만일 경우 도막 형상이 불량하고 임계치를 초과할 경우 성형도구를 통한 무늬 형성시 성형도구가 들러붙지 않도록 하는효과가 미비하게 된다.In addition, isobutyl methacrylate is a component that improves adhesion between components and has excellent drying and weather resistance. If it is less than the critical value, the shape of the coating film is poor, and if it exceeds the critical value, the molding tool stops when forming patterns through the molding tool. The effect of preventing sticking becomes insignificant.
정리하면, 상술한 분말수지는 임계치 미만이면 부착강도가 미약하고, 수축시 변형 발생으로 인해 성형도구 사용시 형상유지가 어렵게 됨은 물론, 도막형상이 불량하게 되고, 임계치를 초과할 경우에는 더 이상의 증진된 부착력을 발휘하기 어렵게 됨은 물론, 성형도구를 통한 무늬 형성시 성형도구가 들러붙지 않도록 하는 효과가 미비하게 된다.In summary, if the above-mentioned powdered resin is less than the critical value, the adhesive strength is weak, and deformation occurs during shrinkage, making it difficult to maintain the shape when using a molding tool, and the shape of the coating film is poor. It becomes difficult to exhibit adhesion, and the effect of preventing the molding tool from sticking when forming a pattern through the molding tool is insignificant.
다음으로, 석고는 본 발명에 따른 조성물이 양생 후 균열 발생을 억제함은 물론 조기강도를 촉진하고 내구성을 증가시키기 위해 사용되는데 임계치를 벗어나 사용할 경우 전체적인 강도 발현이 이루어지지 않는 문제가 발생한다.Next, gypsum is used to suppress the occurrence of cracks after curing of the composition according to the present invention, promote early strength and increase durability, but when used beyond the critical value, a problem occurs that the overall strength is not achieved.
다음으로, 탄산칼슘은 칼슘의 탄산염으로 대리석·방해석·선석(霰石)·석회석·백악·빙주석(氷洲石)·조개껍질·달걀껍질·산호 등에서 산출된다. 시멘트의 주원료, 산화칼슘의 원료, 제철·건축재료 등의 각종 중화제(中和劑)로 사용된다.Next, calcium carbonate is a carbonate of calcium and is produced from marble, calcite, berth, limestone, chalk, glacial stone, clam shells, egg shells, and corals. It is used as a main raw material of cement, a raw material of calcium oxide, and various neutralizing agents such as iron and building materials.
이러한, 탄산칼슘은 제조방법에 따라 중질탄산칼슘과 경질탄산칼슘 2가지로 크게 구분된다.These calcium carbonates are largely divided into two types, heavy calcium carbonate and light calcium carbonate, depending on the manufacturing method.
중질탄산칼슘은 백색결정질 석탄석을 분쇄·분급시켜 제조된 탄산칼슘으로 백색도가 높기 때문에, 백색 탄산칼슘으로 불린다. 입경은 대개 5㎛이하이며 각종 공업용 filler, 식품첨가물, 의약용에 사용된다.Ground calcium carbonate is calcium carbonate produced by crushing and classifying white crystalline coal stone and is called white calcium carbonate because of its high degree of whiteness. The particle diameter is usually less than 5㎛ and is used for various industrial fillers, food additives, and medicines.
경질탄산칼슘은 석탄석을 소성시켜 화학적으로 제조된 탄산칼슘으로서 경미성 탄산칼슘으로도 불린다. 경질탄산칼슘 중에서도 특히 입자의 크기가 0.1 ∼ 0.002㎛정도로 세공인 것을 콜로이드성 탄산칼슘이라 하며, 1㎛이상의 방추형, 주상형 입자의 경진 탄산칼슘과는 구분되어 불리고 있다.Precipitated calcium carbonate is chemically produced calcium carbonate by calcining coal stone, and is also called light calcium carbonate. Among precipitated calcium carbonates, especially those with pores of about 0.1 to 0.002 μm in particle size are called colloidal calcium carbonate, and are called separately from precipitated calcium carbonate with fusiform or columnar particles of 1 μm or more.
본 발명에서는 경질탄산칼슘을 사용하여 흐름성을 제어하면서 미장 마감 조성물로서 제품의 안정성을 위해 이용하게 된다.In the present invention, precipitated calcium carbonate is used for product stability as a plaster finish composition while controlling flowability.
다음으로, 경화촉진제는 시멘트의 성분인 C3S(3CaO·SiO2)의 수화촉진을 위해 사용되는 것으로 본 발명에서는 포름산칼슘(Ca(HCO2)2)을 이용하고 있다.Next, the hardening accelerator is used to promote hydration of C 3 S (3CaO·SiO 2 ), which is a component of cement, and calcium formate (Ca(HCO 2 ) 2 ) is used in the present invention.
상기와 같은 경화촉진제는 임계치 미만으로 혼합할 경우 첨가에 따른 효과가 거의 없으며, 반대로 임계치를 초과할 경우, 유동성이 급격히 저하되어 타설 시간 제어가 어려워져서 사용이 어렵게 되며 강도 역시 저하되는 경향을 나타낸다.When the curing accelerator is mixed below the critical value, there is little effect of addition, and on the contrary, when the critical value is exceeded, the fluidity rapidly deteriorates, making it difficult to control the pouring time, making it difficult to use and the strength also tends to decrease.
다음으로, 개질제는 전분으로 이루어진 것으로 조성물의 점도 차이로 인하여 공기가 인입되는 것을 억제하기 때문에 조성물의 습윤성, 보수성 및 작업가능시간을 향상시켜 성형도구를 이용한 무늬 형성시 습윤성을 유지하여 반복적으로 성형도구를 이용한 무늬 형성이 가능하게 되는데, 이를 임계치 미만으로 혼합할 경우 습윤특성이 불충분한 문제점이 발생하게 되고, 임계치를 초과할 경우 강도 저하 현상을 발생할 수 있다.Next, since the modifier is made of starch and suppresses the inflow of air due to the difference in viscosity of the composition, it improves the wettability, water retention and workable time of the composition to maintain wettability when forming patterns using molding tools to repeatedly mold tools It is possible to form a pattern using , and when mixed below the critical value, a problem of insufficient wetting properties may occur, and when the threshold value is exceeded, a strength decrease phenomenon may occur.
다음으로, 모래는 필러로서 이용되는 것으로 별도의 설명은 생략한다.Next, sand is used as a filler and a separate description thereof is omitted.
다만, 본 발명에서읨 모래는 다양한 입도를 가진 모래를 이용하게 된다.However, in the present invention, sand having various particle sizes is used.
다음으로, 증점제는 본 발명에 점도를 증가시키기 위한 것으로 본 발명에서는 셀룰로오스계를 사용되며, 상기 증점제를 임계치 미만으로 혼합할 경우 사용자가 요구하는 점착력을 기대할 수 없고, 임계치를 초과할 경우 시멘트의 압송성에 지장을 초래할 수 있다.Next, the thickener is for increasing the viscosity in the present invention, and in the present invention, a cellulose-based material is used. When the thickener is mixed below a critical value, the adhesive force required by the user cannot be expected, and when the thickener exceeds the critical value, the pressure of cement It can harm sexuality.
다음으로, 소포제는 기포발생을 억제하기 위한 것으로 상세한 설명은 생략한다.Next, the defoaming agent is for suppressing the generation of bubbles, and a detailed description thereof will be omitted.
본 발명은 상술한 바와 같이 건물 외벽 등의 바탕면에 미장시 분말수지에 의해 다양한 바탕면에 미장이 가능함은 물론, 미장 후 성형도구를 이용한 무늬 형성시 무늬 형상이 그대로 유지되며, 반복적인 성형도구 사용시에도 무늬 형성이 가능하여 다양한 무늬와 모양을 연출할 수 있고, 더욱이, 성형도구 사용시 성형도구에 묻어나지 않게 되어 더욱 무늬를 유지할 수 있는 효과를 얻을 수 있게 된다.As described above, the present invention enables plastering on various base surfaces by means of powder resin when plastering on the base surface such as the outer wall of a building, and the shape of the pattern is maintained as it is when forming patterns using molding tools after plastering, and when repeatedly using molding tools It is possible to form Edo patterns, so that various patterns and shapes can be produced, and moreover, when using a molding tool, it is not smeared on the molding tool, so that the effect of maintaining the pattern can be obtained.
