Description

건축물의 온돌바닥 난방용 자기수평성을 갖는 시멘트계 모르타르 조성물Cement Mortar Composition with Self-Horizontality for Heating Floor of Building

본 발명은 온수배관이 설치되는 건축물 온돌바닥의 난방용에 사용되는 자기수평성(Self Leveling)을 갖는 시멘트계 모르타르 조성물에 관한 것으로서 특히, 난방배관부위의 균열 및 박리현상의 감소, 표면 수평성 향상, 경량성, 원적외선 효과를 부여함을 특징으로 하는 것이다.The present invention relates to a cement-based mortar composition having self leveling used for heating a building's underfloor on which hot water pipes are installed. In particular, the cracks and peeling of heating pipes are reduced, surface leveling is improved, and light weight. It is characterized by imparting sex and far-infrared effects.

주택, 상용건물, 구조물등 대부분의 건축에 있어서, 바닥, 벽 혹은 천정 공사의 마감재료로서 통상 모르타르(Mortar)라고 부르는 시멘트 조성물이 보편적으로 사용되고 있다. 모르타르는 대개 건축 현장에서 골재와 시멘트를 임의의 비율로 혼합하고 여기에 물을 혼합하여 어느정도 점착력(粘着力)을 가지게 된 상태의 시멘트 조성물을 말한다. 상기한 바와같이 혼합한 모르타르는 여러가지 다양한 도구를 이용하여 바닥, 벽, 천정등의 건축물 부위에 바르게 되고 일정한 양생 기간을 통하여 경화, 건조시키면 강도를 발휘하게 되는 것이다. 국내 건축물에 시공되는 모그타르는 콘크리트, 블록, 경량 기포 콘크리트 등 시공대상의 종류에 따라 배합비의 차이가 있으나, 통상 시멘트 100중량부에 대하여 골재 200∼520중량부, 물 50∼100중량부 정도로 이루어지고 있으며 이때 바람직한 골재는 강변 및 해안 등지에서 쉽게 구할 수 있는 모래를 이용하게 된다.In most constructions such as houses, commercial buildings and structures, cement compositions commonly referred to as mortars are commonly used as finishing materials for floor, wall or ceiling construction. Mortar generally refers to a cement composition in which aggregates and cement are mixed in an arbitrary ratio at a construction site and water is mixed therein to have a certain adhesive strength. The mortar mixed as described above is applied to various building parts such as floors, walls, and ceilings by using various tools, and when hardened and dried through a certain curing period, strength is exerted. The mog tar used in domestic buildings has different mixing ratios depending on the type of construction targets, such as concrete, block, lightweight foamed concrete, etc., but it is usually made of 200 to 520 parts by weight of aggregate and 50 to 100 parts by weight of water based on 100 parts by weight of cement. In this case, the preferred aggregate is sand which can be easily obtained from riversides and shores.

본 발명은 건축물의 바닥을 마감하는데 사용되는 시멘트 주제의 조성물로서, 예컨대 아파트, 단독주택, 연립주택등 바닥 온돌에 의하여 건물의 내부를 가열 및 보온시킬 경우, 물과 함께 혼합하여 사용함에 의하여 그 마감 재료로 사용할 수 있는 조성물에 관한 것이다.The present invention is a cement-based composition used to finish the floor of a building, such as apartments, single-family houses, townhouses, etc. When heating and warming the interior of the building by floor ondol, the finish by mixing with water used It relates to a composition that can be used as a material.

건축용 모르타르는 통상 압축 강도 150kgf/㎠, 시공 두께 24mm 이상으로 하도록 건축 관련 법규집에 규정되어 있고 대개 수작업에 의하여 혼합과 시공이 이루어진다. 이러한 모르타르는 현재 토목 및 건축분야에 광범위하게 사용하고 있고 바닥 가온에 의한 난방을 위한 바닥 시공재로도 사용되는 기재이다. 그러나 모르타르는 높은 작업수량(作業水量)에 의하여 건조 수축시의 균열(Crack) 및 박리현상, 강도 저하등의 문제가 발생하고 특히 건물이 고층화 되어감에 따라 운반의 어려움이 따르는 등 많은 문제점을 내포하고 있다. 또한 표면의 침출물 발생, 흙손 마감 작업에 따른 요철등이 문제로 대두되고 있으며, 현장 배합에 의하여 국부적으로 불균질한 상태를 나타내는데 따른 단점등이 있다. 따라서 종래의 모르타르보다 시공이 간편하고 더우기 시공후 상주 사용자의 요구에 충족한 제물성을 내기 위한 모르타르 재료의 개발 또는 개선이 요구되고 있다. 본 발명과 유사한 자기 평활성의 조성물이 국내외에서 여러차례 특허 등의 방법으로 제안된 바 있으나 높은 수평도에도 불구하고 난방 배관 부위에서의 균열으로 인해 열손실이 크게 발생하여 주거 시설 사용에서 만족할만한 효과를 얻지 못하고 있다.Building mortars are usually specified in the building codes to have a compressive strength of 150kgf / ㎠ and a construction thickness of 24mm or more, and are usually mixed and constructed by manual work. These mortars are widely used in civil engineering and construction, and are also used as floor construction materials for heating by floor heating. However, mortar has many problems such as cracking, peeling phenomenon, and deterioration of strength during drying shrinkage due to high working quantity, and in particular, difficulty in transporting as the building becomes higher. Doing. In addition, the surface of the leaching, irregularities due to the trowel finishing work, etc. are emerging as a problem, there is a disadvantage such as showing a local heterogeneous state by the on-site compounding. Therefore, there is a need for development or improvement of a mortar material for producing a product that is easier to install than conventional mortars and further meets the needs of a resident user after construction. Although the composition of self-smoothness similar to the present invention has been proposed by a number of patents at home and abroad, the heat loss is generated largely due to cracks in the heating pipes despite high horizontality, so that a satisfactory effect is obtained in the use of residential facilities. I can't.

본 발명품은 전기한 종래 공법의 단점을 보완하고, 바닥 난방 시공시 소비자의 욕구를 충족 시키기 위하여 개발된 것이며, 특히 균열 및 박리현상의 감소, 표면의 수평성 향상, 경량성, 원적외선 효과를 부여하고자 하였다.The present invention was developed in order to supplement the disadvantages of the conventional method described above, and to meet the needs of consumers during the floor heating construction, in particular to reduce the cracking and peeling phenomenon, improve the horizontality of the surface, light weight, far-infrared effect It was.

이하 본 발명에 대하여 좀더 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail.

본 발명에서는 시멘트가 수화반응(水和反應)에 의하여 강도가 형성되는 것과 아울러 석고와 알루미나계 수경성 재료를 동시 반응시켜 침상의 결정인 에트린자이트(Ettringite)를 형성시킴에 의하여 출발된다. 석고와 알루미나계의 수화는 물이 존재할 경우 초기에 본래의 물질보다 비준이 낮은 특수 결정구조가 생성되며 이를 에트린자이트 칼슘과 알루미늄의 수화황산염)라고 한다. 이와같이 에트린자이트를 형성할때 비중이 낮아지기 때문에 스스로 팽창되어 시멘트와 시멘트 또는 시멘트와 모래 사이에 있는 공극이 없어지고 전반적으로 매우 치밀하게 된다. 본래 시멘트의 균열은 공극 사이에 있는 물이 증발할 때 서로간의 인력에 의하여 공극을 메워주려고 하는 선수축(線收縮)에 기인되며 이는 장기적으로 물질 이동을 일으키게 되어 기재면에서 탈락ㆍ박리되게 되는 것이다. 에트린자이트는 초기 팽창에 의하여 공극을 극소화 시켜주기 때문에 이후에 발생되는 선수축력을 상쇄시켜 주는 역할을 하며 초기 균열의 안정화에 큰 기여를 한다. 상기의 신수축력 상쇄에 의한 균열의 안정은 바닥난방용 시멘트계 조성물의 중요한 특징이다. 즉 바닥난방용 기재에서는 난방배관 파이프에 의해 기재 각부위의 온도차가 발생하며 이로인한 용력발생으로 균열의 발생위험이 높다. 이에 본 발명은 선수축이 안정되어 균열발생 위험이 없다. 또한 본 발명에서는 특히 물에 용해하여 시멘트와 함께 사용시 유연성과 수분을 자체 보유할 수 있는 보수력을 부여하기 위하여 에틸렌비닐아세테이트수지, 아크릴수지, 폴리비닐알콜수지등을 사용함으로서 장기적인 수축 및 균열 안정효과를 가중하였다. 이러한 수지들은 물속에서 그물 모양의 가교 결합을 가지게 되며 따라서 유연성 신축성을 부여하게 된다. 상기 수지는 시멘트 100중량부에 대하여 1∼20중량부 사용함이 바람직하며 이 양이 지나치게 많을 경우 유동성이 크게 저하되어 자기수평의 특성을 발휘하기 어렵다.In the present invention, the cement is started by forming strength by the hydration reaction and simultaneously reacting gypsum with an alumina-based hydraulic material to form needle crystals, Ettringite. Gypsum and alumina-based hydration creates a special crystal structure that initially has lower ratification than the original material when water is present, which is called hydrated sulfate of ethrinzite calcium and aluminum. In this way, the specific gravity is lowered when forming ethrinite, so it expands by itself, thereby eliminating voids between cement and cement or cement and sand, and becoming very dense overall. Originally, the crack of cement is caused by the bow axis trying to fill the pores by the attraction of each other when the water between the pores evaporates, which causes long-term mass transfer, causing them to fall off and peel off from the surface of the substrate. . Ethrinzite minimizes voids by initial expansion, so it counteracts the later bowing force and contributes to stabilization of early cracking. The stabilization of the crack by the above-mentioned elastic shrinkage cancelation is an important feature of the cement composition for floor heating. That is, in the floor heating substrate, the temperature difference occurs at each part of the substrate by the heating pipe, and thus the risk of cracking is high due to the generation of heat. Therefore, the present invention is stable bowed shaft does not have the risk of cracking. In addition, in the present invention, by using ethylene vinyl acetate resin, acrylic resin, polyvinyl alcohol resin and the like to dissolve in water to give flexibility and water retention capacity when used with cement, long-term shrinkage and cracking stabilization effects are achieved. Weighted. These resins will have a net-shaped crosslink in water and thus give flexibility and flexibility. It is preferable that the resin is used in an amount of 1 to 20 parts by weight based on 100 parts by weight of cement. When the amount is excessively large, fluidity is greatly reduced, and thus it is difficult to exhibit the characteristics of self-horizontality.

이러한 수지는 침상의 에트린자이트 사이에 서로 엉켜 미세 공극까지 채워주고 적절한 보수력에 의하여 장기적인 수축 및 균열이 발생하지 않게 하며 이때 특히 석회석을 동시 사용함에 의하여 그 효과는 더욱 커진다. 또한 미립의 석회석은 그 성질상 물과 혼합시 점도 상승 효과를 발휘하여 매우 강한 점착성(粘着性)을 나타내며 미립 석회석이 그물모양의 수지의 가교 결합 중간에 결합되어 시멘트, 모래등 물질의 이동을 억제하는 역할을 하게 되는 것이다.These resins are entangled with each other between the needle-like ethrinzide to fill the fine pores, and long-term shrinkage and cracking do not occur by proper water retention, and in particular, the effect is further increased by simultaneously using limestone. In addition, fine limestone exhibits a very strong adhesiveness due to its viscosity when mixed with water, and exhibits very strong adhesiveness. Fine limestone is bonded in the middle of crosslinking of a net-like resin to suppress the movement of materials such as cement and sand. It will play a role.

본 발명에 사용되는 석고는 무수 석고(CaSO4), 반수 석고(CaSO4ㆍ1/2 H2O), 이수 석고(CaSO4ㆍ2H2O)등이 사용될 수 있으며 특히 반응 효과를 확실히 하기 위하여 무수 석고를 사용함이 바람직하다. 석고의 사용량을 시멘트 100중량부에 대해 5∼50중량부를 사용하고 있으며 석고의 사용은 알루미나계 수경성 재료의 사용량에 따라 결정되어 있다. 우선 석고의 사용량은 알루미나계 수경성 재료에 대해 50∼70중량%를 사용하여야 하는데 석고의 양이 이보다 적을 경우는 팽창의 효과를 발휘하기 힘들며 강도형성이 어렵다. 석고의 양이 지나치게 많을 경우는 팽창이 지나치게발생하여 표면에 미세균열이 발생하며 강도저하의 우려가 있다. 알루미나계 수경성 재료로서는 알루미나 시멘트, 비정질 알루미나 미립자등 활성도가 높은 알루미나 성분이면 가능하다. 알루미나계 수경성 재료 시멘트 100중량부에 대해 10∼70중량부를 사용하며 그 사용량이 많을 경우는 조성물의 응결이 빨라져 유동성 손실이 크며 장기 강도를 해칠 우려가 있다. 반대로 그 사용량이 너무 적을 경우는 부유물 발생이 심하며 경화가 늦어진다. 이때 반응이 너무 빨리 진행되면 초기 작업성이 나빠지므로 유기산을 이용한 적절한 경화 시간의 조절이 필요하다. 유기산은 구연산, 개미산, 주석산 등이 있으며, 물에 잘 녹는 친수성 유기산이어야 한다. 또한 본 발명의 특징으로 조성물의 경량화를 들 수 있다.As the gypsum used in the present invention, anhydrous gypsum (CaSO 4 ), hemihydrate gypsum (CaSO 4 .1 / 2 H 2 O), dihydrate gypsum (CaSO 4 2H 2 O), and the like may be used. Preference is given to using. The amount of gypsum used is 5 to 50 parts by weight based on 100 parts by weight of cement, and the use of gypsum is determined by the amount of alumina-based hydraulic material used. First of all, the amount of gypsum used should be 50 to 70% by weight based on the alumina-based hydraulic material. If the amount of gypsum is less than this, the effect of expansion is difficult and strength is difficult to form. If the amount of gypsum is too large, expansion may occur excessively, and microcracks may occur on the surface, and the strength may be reduced. The alumina-based hydraulic material may be any alumina component having high activity such as alumina cement and amorphous alumina fine particles. 10 to 70 parts by weight based on 100 parts by weight of the alumina-based hydraulic material cement is used, and if the amount is large, the condensation of the composition may be accelerated, resulting in a large loss of fluidity and damage to long-term strength. On the contrary, when the amount is too small, floating matters are generated severely and curing is delayed. At this time, if the reaction proceeds too fast, the initial workability is deteriorated, so it is necessary to control the appropriate curing time using an organic acid. Organic acids include citric acid, formic acid, tartaric acid, etc., and should be hydrophilic organic acids that are soluble in water. Moreover, the weight of a composition is mentioned as a characteristic of this invention.

본 발명에서 사용되는 골재는 시멘트 100중량부에 대하여 50∼200중량부 사용하며 모래 및 경량골재로 이루어지는 혼합골재 또는 경량골재, 맥반석으로 구성되는 혼합골재를 사용하며 인공경량골재 또는 맥반석은 전체 골재 사용량 대비 각각 20∼100중량% 사용한다. 본 발명에 혼합 사용된 골재는 특히 인공경량골재로서 이의 제조방법은 돌로마이트, 플라이 애쉬 등을 습식 성형기에서 구상 성형한 후 1200℃ 내외에서 발포시켜 사용하며 입도 1.0∼10mm, 비중 0.5∼2.0을 갖는 것이다. 본 경량골재 사용시 저비중 뿐만아니라 난방에 필요한 축열 성능을 보유하여 시공성 및 물리적 성능의 향상을 가져올 수 있다.Aggregate used in the present invention is used 50 to 200 parts by weight based on 100 parts by weight of cement and use a mixed aggregate consisting of sand and light aggregate or a light aggregate, mixed aggregate consisting of ganban stone and artificial light aggregate or ganban stone Use 20 to 100% by weight, respectively. The aggregate used in the present invention is an artificial lightweight aggregate, in particular, a method for producing the same, which is used for spherical molding of dolomite, fly ash, etc. in a wet molding machine, and then foamed at around 1200 ° C. with a particle size of 1.0 to 10 mm and a specific gravity of 0.5 to 2.0. . When using this lightweight aggregate, it can bring about low specific gravity as well as heat storage performance required for heating, resulting in improved construction and physical performance.

또한 혼합골재로서 골재의 기능 이외에 본 발명의 효용성 증대를 위하여 맥반석을 사용하여 원적외선 방사율 향상 효과를 기대할 수도 있다. 원적외선(Deep-Ultrared-Ray)은 인체에 흡수시 건강 증진에 도움을 주는 것으로 알려져 있으며 본발명에 사용되는 모래 대신 입도 0.1∼10mm, 비중 1.0∼3.0의 원적외선 효과가 풍부한 맥반석을 혼합하여 사용할 경우 난방층에서의 원적외선 방사율을 높여줄 수 있다.In addition, in addition to the function of the aggregate aggregate as a mixed aggregate may be expected to improve the far-infrared emissivity by using elvan to increase the efficacy of the present invention. Deep-Ultrared-Ray is known to help improve health when absorbed by the human body, and heating is used when a mixture of ganban stones with a particle size of 0.1 to 10 mm and a specific gravity of 1.0 to 3.0 is used instead of the sand used in the present invention. It can increase far-infrared emissivity in layers.

이러한 방식으로 얻어진 본 발명은 바닥 난방용 바름재로 사용시 종래의 단점들을 개선할 수 있는 것이며, 이하 본 발명은 좀더 구체화 하기 위하여 다음의 실시예를 들어 설명한다.The present invention obtained in this manner can improve the disadvantages of the conventional when used as a floor heating varnish, the present invention will be described by the following examples in order to be more specific.
