아파트나 다세대 주택과 같은 공동주택에서는 콘크리트 슬래브 위에 시공되는 재료가 거의 시멘트 재료로 되어있어 단열성능이 떨어지며 시멘트 재료의 단점인 수축으로 인한 균열이 발생하여 층간 소음, 진동이 발생하는데 이러한 상, 하층 간의 소음 진동으로 인하여 분쟁이 발생하기도 한다.In multi-unit houses such as apartments or multi-family houses, the material that is constructed on the concrete slab is almost made of cement material, which insulates its insulation performance and causes cracks due to shrinkage, which is a disadvantage of cement material, resulting in interlayer noise and vibration. Disputes arise from noise and vibration.

(20 mm thick), aerated concrete is poured on it, heating pipes are installed on it, cement mortar is placed on it, and finished with wood or vinyl sheets.
그러나 이러한 방법에 있어서 스치로폼이나 고무패드는 접착시간, 접착비용, 재료비, 복잡한 설치 조건 등으로 비용이 많이 소요되며 이러한 스치로폼이나 고무패드 위에 타설되는 시멘트 기포콘크리트가 접착이 잘 안되어 들뜨는 현상이 일어날 수 있으며 균열이 많이 발생하고 있고 시멘트 기포콘크리트 위에 시공되는 시멘트 모르타르 또한 균열이 발생하게 된다. 이러한 요인들로 인하여 전체적으로 비용도 많이 들고 소음. 진동 방지효과를 얻지 못하고 있는 실정이다.However, in this method, styrofoam or rubber pads are expensive due to adhesion time, adhesion cost, material cost, and complicated installation conditions, and cement foamed concrete placed on such styrofoam or rubber pads may not be easily adhered to lift. A lot of cracks are generated and the cement mortar that is constructed on the cement foam concrete is also cracked. These factors are both costly and noisy overall. It is a situation that does not obtain the vibration prevention effect.

본 발명의 조성물은 공동주택 건축물 바닥에 사용 시 균열이 발생하지 않으며 단열성능이 우수하게 되고 바닥 충격음을 방지하는 차음 성능이 우수하며 소요 비용도 절감되는 효과가 있다.The composition of the present invention does not generate cracks when used in the multi-family building floor, the heat insulation performance is excellent, the sound insulation performance to prevent the floor impact sound is excellent and the required cost is reduced.
이하 본 발명에 따른 공동주택 건축물의 바닥충격음 방지와 단열 및 무균열의 바닥재 조성물에 대해 보다 상세히 설명한다.Hereinafter, the floor shock sound prevention and heat insulation and crack-free flooring composition of the multi-family building according to the present invention will be described in detail.
본 발명의 조성물은 석고 10-80중량%, 슬래그 시멘트 10-80 중량%, CAS 5 -20 중량%, 왕겨 목은 볏짚 1-30 중량%, 응결촉진제 0.5-5 중량%를 분말 상태로 혼합 조성하여 이루어진다.The composition of the present invention is a mixture of 10-80% by weight of gypsum, 10-80% by weight of slag cement, 5-20% by weight of CAS, 1-30% by weight of rice straw rice straw, 0.5-5% by weight of coagulant accelerator in powder form It is done by
본 발명에 사용되는 석고는 입자가 100㎛ 체 구멍을 통과한 것을 사용하는데 이는 석고가 아래에서 설명되는 기포제와 결합하여 일정한 크기의 미세한 기포를 형성하게 하여 소리를 골고루 분산시켜 차음효과를 높이고 제품의 강도를 우수하게 얻기 위해서이다. 석고 자체 물성이 단열성, 불연성, 무수축성, 경량성이므로 이를 활용하고 그 입자를 미세하게 하여 강도 또한 상승되게 한다. 석고는 10-80중량% 범위가 바람직한데 많이 사용할수록 좋으나 80중량% 이상이면 기포형성으로 강도가 하락할 수가 있고 10중량% 이하이면 제품의 효과와 성능이 저하될 우려가 있다.The gypsum used in the present invention uses that the particles passed through the 100㎛ sieve hole, which is combined with the foaming agent described below to form a fine bubble of a certain size to evenly disperse the sound evenly to increase the sound insulation effect of the product This is to obtain excellent strength. Since gypsum itself is insulated, non-combustible, non-shrinkable, and lightweight, it is used to make it finer and its strength is increased. The gypsum is preferably in the range of 10-80% by weight, but the more it is used, the more it is 80% by weight or more, the strength may decrease due to bubble formation, and in the case of 10% by weight or less, the effect and performance of the product may be deteriorated.
CAS(칼슘 알루미노 설포네이트)는 시멘트 제품에 주로 사용되는 재료로서 시 멘트 팽창제, 초속경 시멘트, 고강도시멘트, GROUT재 등에 사용되는 재료로서 본 발명에서는 조성물의 응결촉진과 강도보완을 위해 사용되는데 3-30중량% 범위로 사용되는 것이 바람직하다. 3중량% 이하이면 큰 효과를 얻지 못하며 30중량% 이상이면 강도는 상승하지만 경제성이 떨어지고 급속한 응결이 발생한다. Calcium alumino sulfonate (CAS) is a material mainly used for cement products, such as cement expanders, cemented carbide cements, high strength cements, GROUT materials, and the like. It is preferred to use in the range -30% by weight. If it is less than 3% by weight, no significant effect is obtained. If it is more than 30% by weight, the strength is increased, but the economic efficiency is low, and rapid condensation occurs.
슬래그 시멘트는 석고의 강도 보완을 위하며 사용하는 것으로서 10-80 중량%의 범위로 사용하는 것이 바람직하다. 80중량% 이상이면 강도는 상승하지만 반대로 석고의 성질이 감량되며 10중량% 이하이면 효과가 떨어진다. Slag cement is used to supplement the strength of gypsum and is preferably used in the range of 10-80% by weight. If it is more than 80% by weight, the strength is increased, but conversely, the property of gypsum is reduced, and if it is less than 10% by weight, the effect is reduced.
응결촉진제로는 주로 생석회, 소석회, K2SO4, Na2CO3, Al2(SO4)3 등이 사용될 수 있으며 0.05-3중량%의 범위로 사용하는 것이 강도를 상승시킬 수 있어 바람직하다. 이러한 응결촉진제를 3중량% 이상 사용하면 응결이 너무 빠르게 일어나 급결이 올 수 있으며 0.05중량%이하이면 효과를 볼 수 없다. As a coagulant, mainly quicklime, hydrated lime, K 2 SO 4 , Na 2 CO 3 , Al 2 (SO 4 ) 3, etc. may be used, and it is preferable to use it in the range of 0.05-3% by weight to increase the strength. . If 3% by weight or more of such a coagulation accelerator is used, condensation may occur too quickly, resulting in rapid condensation.
본 발명의 왕겨나 볏짚은 섬유소를 60%이상을 갖고 있는 친환경 재료로서 바이오 미생물배양원료, 천연벽지, 동물사료용 및 주택 내벽의 습도 조절제 등으로 널리 사용되고 있는 친환경의 고급재료로서 쉽게 구입할 수 있고 경제성 있는 천연의 재료로서 본 발명에서는 0.01㎛-4㎛로 분쇄하여 사용된다. 본 발명의 왕겨 또는 볏집의 입자가 상기 범위를 벗어나게 되면 기계적 물성이나 제품 물성이 저하될 우려가 있어 상기의 입자 범위가 바람직하다. 이러한 왕겨나 볏짚의 분쇄물은 예부터 점토벽돌이나, 모르타르 등에 균열을 방지하기 위해 사용되어 온 것으로 본 발명제품 조성물에 균열을 방지하는 역할을 하여주며 제품 자체의 신축성이 있어 바닥 충 격음의 흡수나 분산 시키는 완충재 역할을 하며 단열성 또한 크게 증진시킨다. 이러한 본 발명의 왕겨 또는 볏짚은 1-30 중량%의 범위로 사용되는 것이 바람직하다. 1중량% 이하이면 완충효과가 떨어지며 30중량% 이상이면 응결력이 떨어진다.Rice husk or rice straw of the present invention is an eco-friendly material having more than 60% of fiber, and can be easily purchased as an eco-friendly high-quality material widely used as a bio-microbial culture raw material, a natural wallpaper, an animal feed, and a humidity control agent of the inner wall of a house. As a natural material, in this invention, it is used by grind | pulverizing to 0.01 micrometer-4 micrometers. When the grains of the chaff or crest of the present invention are out of the above range, there is a possibility that mechanical or product properties may be deteriorated, so the above particle range is preferable. Such crushed rice husks or rice straws have been used to prevent cracking in clay bricks or mortars since ancient times, which serves to prevent cracking in the composition of the present invention, and the elasticity of the product itself is used to absorb the floor impact sound. It acts as a buffer to disperse and also greatly improves thermal insulation. Such chaff or rice straw of the present invention is preferably used in the range of 1-30% by weight. If it is 1% by weight or less, the buffering effect is inferior. If it is 30% by weight or more, the coagulation force is lowered.
본 발명의 조성물은 펄프 분쇄물을 0.5-5중량%의 범위로 더 포함할 수 있다. 펄프 분쇄물은 왕겨 또는 볏짚과 혼합되어 흡음 및 단열을 위한 완충효과에 상승작용을 제공한다. 본 발명의 펄프 분쇄물이 상기 범위를 벗어나면 완충효과를 볼 수 없다. The composition of the present invention may further comprise a pulp mill in the range of 0.5-5% by weight. The pulp mill is mixed with rice bran or rice straw to provide synergy to the cushioning effect for sound absorption and insulation. If the pulp mill of the present invention is out of the above range, the buffering effect is not seen.
상기와 같은 본 발명의 조성물은 시공시 본 발명의 조성물 100중량%에 대하여 물 80-120중량% 및 기포제 0.05-0.5중량%를 혼합하여 슬러리 상태로 사용된다. 이 경우 물의 양이 80중량% 이하이면 혼합 슬러리의 플로우(Flow)가 낮아 시공이 어려우며, 물의 양이 120중량% 이상이면 시공 후 강도가 하락하는 원인이 될 수 있다.As described above, the composition of the present invention is used in a slurry state by mixing 80-120% by weight of water and 0.05-0.5% by weight of the foaming agent with respect to 100% by weight of the composition of the present invention. In this case, when the amount of water is 80% by weight or less, the flow of the mixed slurry is low, and thus construction is difficult, and when the amount of water is 120% by weight or more, it may cause a decrease in strength after construction.
상기 기포제로는 동물성 또는 식물성 기포제를 사용하는데 이의 사용량은 혼합조성물 100중량%에 대해 0.05-0.5중량%의 범위가 바람직하다. 기포제가 0.05중량% 이하이면 본 발명 조성물의 비중이 높아지게 되고 5중량% 이상이면 기포가 과다하게 발생 되어 비중이 낮아지는 단점이 있다.As the foaming agent, an animal or vegetable foaming agent is used, and the amount thereof is preferably in the range of 0.05-0.5% by weight based on 100% by weight of the mixed composition. If the foaming agent is 0.05% by weight or less, the specific gravity of the composition of the present invention is increased, and when the foaming agent is 5% by weight or more, there is a disadvantage in that the foaming is excessively generated and the specific gravity is lowered.
상기와 같이 혼합된 혼합 슬러리는 공동주택 건축물 콘크리트 슬라브 위에 습식 타설되어 공동주택 건축물의 바닥충격음을 방지하고 단열성을 가짐은 물론 균열이 발생하지 않게 한다. 무엇보다 균열이 발생하지 않음으로 인하여 소음 방지 및 차음효과를 더 크게 얻을 수 있다.The mixed slurry mixed as described above is wet-poured on the concrete slab of the multi-family building to prevent the floor impact sound of the multi-family building and have thermal insulation and also prevent cracking. First of all, it is possible to obtain more noise prevention and sound insulation effect due to no cracking.
이하 상기한 본 발명을 실시예에 의거하여 보다 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to Examples.
