Description
본 발명은 자기수평성 몰탈 조성물에 관한 것으로서, 보다 상세하게는 응결시간이 짧고 유동성 및 강도가 우수한 자기수평성 몰탈 조성물에 관한 것이다.The present invention relates to a self-horizontal mortar composition, and more particularly, to a self-horizontal mortar composition having a short setting time and excellent flowability and strength.
일반적으로 사무실 빌딩, 오피스텔, 백화점 등의 건축물의 경우 바닥면을 평탄화하고 수평으로 유지하기 위한 미장공정이 필수적으로 행해진다. 이러한 바닥면의 미장공정은 전문적인 기술과 경험, 노하우 등을 필요하여 숙련공에 의하여 시공되어야 하는 실정이다.In general, in the case of buildings such as office buildings, officetels, department stores, a plastering process is essential to keep the floor flat and horizontal. This flooring process is required to be constructed by skilled workers, requiring professional skills, experience, and know-how.
특히 최근 많은 소비자로부터 요청되는 바닥 마감재를 고품질로 시공하기 위해서는 시멘트 몰탈로 이루어지는 바닥면의 평탄화가 매우 중요하며, 건축물의 마감재로 널리 사용되는 시멘트 몰탈의 경우 작업자의 숙련 정도에 따라 평탄화 정도가 좌우되며, 시멘트와 모래 등을 혼합하는 비율에 따라 마감면의 품질이 좌우되는 실정이다.In particular, in order to construct high quality floor finishing materials requested by many consumers recently, the flattening of the floor surface made of cement mortar is very important, and in the case of cement mortar widely used as a finishing material for buildings, the degree of leveling depends on the skill of the operator. The quality of the finish depends on the proportion of cement and sand.
최근에는 상기와 같은 문제를 해결하기 위하여 건조 수축에 의한 균열을 최소화하고 평탄성을 부여하기 위하여 자기수평성(self-leveling)을 갖는 몰탈 조성물을 사용하는 기술이 제공되고 있다. 이러한 자기수평성 몰탈 조성물은 물이 중 력에 의하여 자연스럽게 수평면을 이루는 원리를 이용한 것으로, 각각의 결합재에 적당한 유동화제를 첨가하여 물과 반죽한 슬러리 상태로 사용되며, 물과 같이 유동성을 보유하여 평탄한 수평면을 형성하게 된다.Recently, in order to solve the above problems, a technique of using a mortar composition having self-leveling has been provided to minimize flatness and to give flatness due to dry shrinkage. The self-horizontal mortar composition uses the principle that water naturally forms a horizontal plane by gravity, and is used in the form of a slurry kneaded with water by adding an appropriate fluidizing agent to each binder. It will form a horizontal plane.
일반적으로 자기수평성 몰탈 조성물은 시멘트 및 모래나 무기질계 분말을 주원료로 이루어지고, 일반용과 산업용, 박막형과 후막형 등으로 구분된다. 일반용은 사무실 빌딩, 백화점, 전시장, 아파트 등 일반 건물의 복도, 바닥 마감에 주로 사용되고, 산업용은 공장이나 연구실, 주차장 등의 바닥 마감에 주로 사용된다. 또 박막형은 두께 3∼20mm 정도로 시공되고, 후막형은 20mm 이상의 두께로 시공된다. 여기에서 후막형은 바닥면의 굴곡 오차에 관계없이 평활성을 얻을 수 있는 반면에, 박막형은 바닥면의 상태에 따라 완벽한 수평을 이루지 못할 우려가 있다.In general, the self-horizontal mortar composition is composed of cement and sand or inorganic powder as the main raw material, and is divided into general use and industrial, thin film type and thick film type. General use is mainly used for corridor and floor finishing of general buildings such as office buildings, department stores, exhibition halls, apartments, etc., and industrial is mainly used for floor finishing of factories, laboratories, and parking lots. Moreover, the thin film type is constructed about 3-20 mm in thickness, and the thick film type is constructed by thickness of 20 mm or more. Here, the thick film type may obtain smoothness regardless of the bending error of the bottom surface, whereas the thin film type may not be perfectly horizontal depending on the state of the bottom surface.
종래 자기수평성 몰탈 조성물은 주로 포틀랜트 시멘트와 석회석 분말 등을 기재로 하여 골재 및 각종 혼화제 등을 혼합시킨 프리믹싱(premixing)형으로 시공 두께가 박막형의 경우에도 대략 10∼15mm 정도로 두껍게 이루어진다.Conventional self-horizontal mortar composition is a premixing type in which aggregate and various admixtures are mixed based on portland cement and limestone powder, and the thickness of the thin film is about 10 to 15 mm.
종래 자기수평성 몰탈 조성물의 경우 응결시간이 길어 시공성이 나쁘고, 부착강도 및 휨강도 등이 작아 5∼10mm 정도의 두께로 시공되는 경우 층분리 및 균열 등이 발생한다는 문제가 있다.In the case of the conventional self-horizontal mortar composition has a long condensation time, poor workability, there is a problem that the layer separation and cracking occurs when it is constructed with a thickness of about 5 to 10mm due to the small adhesion strength and bending strength.
본 발명의 목적은 상기와 같은 문제점을 해결하기 위한 것으로서, 고미분 혼화재와 섬유화이버, 분말수지 등을 사용하므로 응결시간이 짧고 유동성 및 강도가 우수한 자기수평성 몰탈 조성물을 제공하기 위한 것이다.An object of the present invention is to solve the above problems, and to provide a self-leveling mortar composition having a high condensation time, high fluidity and strength because of using a fine powder admixture, a fiber fiber, a powdered resin and the like.

본 발명의 자기수평성 몰탈 조성물은 원활한 혼합과 균일한 제품의 생산을 위하여 고미분 혼화재, 수축저감제, 섬유화이버, 분말수지, 천연 무기안료, 기타 첨가제 등을 선택적으로 프리믹싱(pre-mixing)한 다음, 시멘트와 모래를 혼합하면서 프리믹싱된 재료 등을 투입하여 고르게 혼합하는 과정으로 제조하는 것이 바람직하다.The self-horizontal mortar composition of the present invention selectively pre-mixes fine powder admixtures, shrinkage reducing agents, fiber fibers, powdered resins, natural inorganic pigments, and other additives for smooth mixing and production of uniform products. Then, it is preferable to prepare a process of evenly mixing the pre-mixed materials and the like while mixing cement and sand.
상기에서 프리믹싱은 1,700∼2,500rpm 정도로 고속회전하는 0.1∼0.5㎥ 용량의 믹서를 이용하여 진행한다. 또 시멘트 및 모래와 프리믹싱된 재료 등을 함께 혼합하는 과정에서는 150∼200rpm 정도의 회전속도를 갖는 믹서를 사용한다.In the above premixing is carried out using a mixer of 0.1 ~ 0.5 ㎥ capacity that rotates at a high speed of about 1,700 ~ 2500rpm. In addition, a mixer having a rotational speed of about 150 to 200 rpm is used when mixing cement, sand, and premixed material together.

The material to be added is selectively premixed as needed.
상기 프리믹싱은 고미분 혼화재, 수축저감제, 섬유화이버, 분말수지, 천연 무기안료, 기타 첨가제 등에서 2가지 이상을 필요에 따라 선택하여 행하며, 1가지 재료만 시멘트와 모래에 직접 투입하는 경우 고르게 혼합이 이루어지지 않는 특성을 갖는 재료를 혼합이 잘 이루어지는 재료와 함께 프리믹싱을 행하는 것이 바람직하다.The premixing is carried out by selecting at least two kinds of high-powder admixtures, shrinkage reducing agents, fiber fibers, powdered resins, natural inorganic pigments, and other additives as necessary, and mixing evenly when only one material is directly added to cement and sand. It is preferable to perform premixing of the material having this non-conforming property together with the material well mixed.

상기와 같이 얻어진 실시예 1 내지 실시예 4 및 비교예의 물성을 한국공업규격인 KS F 4041에 준하여 시험하고 그 결과를 다음의 표 1에 나타낸다.The physical properties of Examples 1 to 4 and Comparative Examples obtained as described above were tested according to Korean Industrial Standard KS F 4041, and the results are shown in Table 1 below.
상기한 표 1로부터 알 수 있는 바와 같이, 본 발명에 따른 자기수평성 몰탈 조성물의 실시예 1 내지 실시예 4는 비교예에 비하여 플로우가 크게 나타나므로 유동성이 우수함을 알 수 있다. 또 종결까지 걸리는 응결시간이 2시간 25분에서 4시간 20분까지 단축되므로, 시공에 소요되는 시간은 크게 절약하는 것이 가능하다. 그리고 휨강도, 압축강도, 부착강도가 비교예에 비하여 향상됨을 알 수 있으며, 수축에 따른 길이변화가 적음을 알 수 있다.As can be seen from Table 1, Examples 1 to 4 of the self-horizontal mortar composition according to the present invention can be seen that the flow is excellent compared to the comparative example because the flow is excellent. In addition, the condensation time until the end is shortened from 2 hours 25 minutes to 4 hours 20 minutes, it is possible to greatly save the time required for construction. In addition, it can be seen that the bending strength, the compressive strength, and the adhesion strength are improved as compared with the comparative example, and the change in length due to shrinkage is small.
상기에서는 본 발명에 따른 자기수평성 몰탈 조성물의 바람직한 실시예에 대하여 설명하였지만, 본 발명은 이에 한정되는 것이 아니고 특허청구범위와 발명의 상세한 설명의 범위 안에서 여러가지로 변형하여 실시하는 것이 가능하고, 이 또한 본 발명의 범위에 속한다.In the above, a preferred embodiment of the self-horizontal mortar composition according to the present invention has been described. However, the present invention is not limited thereto, and various modifications can be made within the scope of the claims and the detailed description of the invention. It belongs to the scope of the present invention.
상기와 같이 이루어지는 본 발명에 따른 자기수평성 몰탈 조성물에 의하면, 고미분 혼화재, 섬유 화이버, 분말수지 등을 사용하므로, 응결시간이 짧아 시공성이 우수하며, 부착강도 및 휨강도 등이 우수하여 3∼10mm 정도의 두께로 바닥면을 시공하는 경우에도 층분리 및 균열이 발생하지 않는다.According to the self-horizontal mortar composition according to the present invention made as described above, since the fine powder admixture, fiber fibers, powder resin, etc. are used, the setting time is short, the workability is excellent, the adhesion strength and the bending strength are excellent, 3 to 10 mm Even when the floor is constructed to a thickness, the separation and cracking do not occur.
또 본 발명에 따른 자기수평성 몰탈 조성물에 의하면, 고미분 혼화재, 섬유 화이버, 분말수지 등을 프리믹싱하므로, 소량으로 첨가되는 재료가 고르게 혼합되어 전체적으로 균일한 물성을 갖게 된다.In addition, according to the self-horizontal mortar composition according to the present invention, the pre-mixing of the fine powder admixtures, fiber fibers, powder resins, etc., so that a small amount of the added material is evenly mixed to have a uniform physical property as a whole.
