이하 본 발명에 따른 저발포용 우레탄 폼과 초고속 경화형 폴리우레아를 이용한 단열.방수.방음제의 조성물 및 제조과정과 그 도포방법을 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, a composition, a manufacturing process, and a coating method of a heat-insulating, waterproofing, and soundproofing agent using a low-foaming urethane foam and an ultrafast curing type polyurea according to the present invention will be described in detail with reference to the accompanying drawings.
먼저, 본 발명은 단열제 기능을 갖는 저발포용 우레탄 폼과 방수.방음제 기능을 갖는 초고속 경화형 폴리우레아로 이루어지며, 상기 저발포용 우레탄 폼은 경화제 역할을 하는 제 1 프리폴리머와, 상기 제 1 프리폴리머와 혼합시 발포 및 경화되어 실질적인 단열제의 역할을 하는 제 1 수지용액으로 구성된다.First, the present invention is made of a low-foaming urethane foam having a thermal insulation function and an ultra-fast curing polyurea having a waterproof and soundproofing agent function, the low-foaming urethane foam is a first prepolymer to act as a curing agent, and the first prepolymer It is composed of a first resin solution which is foamed and cured when mixed with a substantially insulating agent.
여기서 일반적인 우레탄 폼의 경우 발포 두께가 20~50mm이나, 저발포 우레탄 폼은 발포 두께가 5~10mm로 고경도, 고강도 우레탄 폼으로 단열층을 형성하는 것으로 이하 '저발포 우레탄 폼'이라 약칭한다.Here, in the case of a general urethane foam, the foam thickness is 20 to 50mm, but the low foamed urethane foam has a foam thickness of 5 to 10mm and forms a heat insulation layer with high hardness and high strength urethane foam, hereinafter referred to as 'low foamed urethane foam'.
또한, 방수.방음제 기능을 갖는 초고속 경화형 폴리우레아는 경화제 역할을 하는 제 2 프리폴리머와, 상기 제 2 프리폴리머와 혼합시 신율, 탄성율, 내마모성, 방음성, 내구성 등을 가져 실질적인 방수.방음제로서 역할을 하는 제 2 수지용액으로 구성된다.In addition, the ultra-fast curing polyurea having a waterproof and soundproofing agent has a second prepolymer which acts as a curing agent and an agent that acts as a practical waterproof and soundproofing agent by having elongation, elasticity, abrasion resistance, soundproofing and durability when mixed with the second prepolymer. It consists of two resin solutions.
상기 저발포용 우레탄 폼을 구성하는 제 1 프리폴리머은 28~34% NCO 메틸렌 디이소시아네이트 100wt%로 이루어진 것으로서, 상기 메틸렌 디이소시아네이트는 전체 경도와 내후성, 신장율 등 물성을 좌우하는 재료로 N=C=O결합(이하 'NCO'라함)을 사용하였으며, NCO 함유량이 높아질수록 경화 후 도막의 경도는 높아지고, NCO 함유량이 낮아질수록 경화 후 도막의 경도는 낮아지는 것으로서, 이러한 NCO 함유량은 본 발명에서는 28~34% NCO 메틸렌 디이소시아네이트를 사용하는 것이 바람직하다.The first prepolymer constituting the low-foaming urethane foam is composed of 28 ~ 34% NCO methylene diisocyanate 100wt%, the methylene diisocyanate is a material that influences the properties such as overall hardness, weather resistance, elongation, N = C = O bond (Hereinafter referred to as 'NCO'), the higher the NCO content, the higher the hardness of the coating after curing, and the lower the NCO content, the lower the hardness of the coating after curing, and the NCO content is 28-34% in the present invention. Preference is given to using NCO methylene diisocyanate.
상기 저발포용 우레탄 폼을 구성하는 제 1 수지용액은 우레탄 폼의 신장율과 인장강도를 조정하는 분자량 400의 폴리올(polyol) 71~80wt%와, 우레탄 폼의 경화시간을 조정하기 위한 분자량 600의 폴리올(polyol) 17~24wt%와, 우레탄 폼의 표면장력을 낮추어 혼화성을 향상시키고 생성된 기포의 크기를 균일하게 하며 폼(foam)의 셀(cell)구조를 조절하여 발포체에 안정성을 부여하는 실리콘 정포제 1~2wt%와, 우레탄 폼의 연소에 대한 방호막을 생성하는 난연제 1~2wt%와, 수지반응을 촉진시키며 반응성의 상승효과를 얻기 위한 촉매 0.2~0.8wt%와, 상기 제 1 프리폴리머와 반응시 이산화탄소(CO2) 가스를 방출시켜 발포를 생성하는 물 0.2~0.8wt%로 이루어진다.The first resin solution constituting the low-foaming urethane foam is a polyol 71 to 80 wt% of a molecular weight 400 to adjust the elongation and tensile strength of the urethane foam, and a polyol having a molecular weight of 600 to adjust the curing time of the urethane foam (polyol) 17 ~ 24wt% and silicone which improves the miscibility by lowering the surface tension of urethane foam, making the size of the bubbles created uniformly and adjusting the cell structure of foam to give foam stability 1 to 2 wt% of foam stabilizer, 1 to 2 wt% of flame retardant to form a protective film against combustion of urethane foam, 0.2 to 0.8 wt% of catalyst for promoting resin reaction and obtaining synergistic effect of reactivity, and the first prepolymer When the reaction is made of 0.2 ~ 0.8wt% of water to release carbon dioxide (CO2) gas to produce a foam.
여기서 상기 분자량 400의 폴리올은 반응 관능기 4가인 자당(sucrose) 성분의 폴리올으로서 작업의 특성상 71wt% 미만으로 첨가되어 질 때에는 도막의 신율이 떨어지며, 80wt%이상이 초과되면 신율과 인장강도는 증가하지만 내구성 저하를 초래함으로써 71~80wt% 범위내가 바람직하다.Here, the polyol having a molecular weight of 400 is a polyol of a sucrose component having a reaction functional group tetravalent, and when elongated below 71wt%, the elongation of the coating is lowered, and when it exceeds 80wt%, the elongation and tensile strength are increased, but durability It is preferable to be in the range of 71 to 80 wt% by causing a decrease.
상기 분자량 600의 폴리올은 반응 관능기 2가인 에틸렌 옥사이드(ethylene oxide) 성분의 폴리올으로서 24wt% 이상 투입될 경우 경화시간이 너무 빠르게 진행되어 외관의 저하와 부착력 저하를 가져오며, 17wt% 미만 첨가될 경우 경화시간이 많이 지연되어 작업 효율이 저하됨으로써 17~24wt% 범위내에서 투입하는 것이 바람직하다.The polyol having a molecular weight of 600 is a polyol of an ethylene oxide component having a reactive functional group, and when more than 24wt% is added, the curing time proceeds too fast, resulting in deterioration of appearance and adhesion, and hardening when added below 17wt%. Since time is delayed a lot and work efficiency falls, it is preferable to add in 17-24 wt%.
상기 실리콘 정포제는 실리옥산 폴리에테르(siloxane polyether)를 사용하는 것으로 2wt% 이상 첨가시에는 요구되는 압축성 특성이 저하됨으로써 이완현상이 발생되고, 1wt% 미만 첨가시 압축성의 특성이 나아지고 이완현상은 없어지는 반면에 표면장력을 낮추기에는 부적합하여 생성된 기포의 크기가 불균일하게 되어 폼의 셀구조 조절이 어려워 발포체에 안정성을 부여할 수 없는 문제점이 있어 1~2wt% 범위내에서 첨가하는 것이 바람직하다.The silicone foam stabilizer uses a siloxane polyether, and when the addition of 2wt% or more is required, the compressibility is reduced, and when the addition is less than 1wt%, the compressibility is better and the relaxation is On the other hand, it is not suitable to lower the surface tension, resulting in a non-uniform size of the resulting bubbles, which makes it difficult to control the cell structure of the foam, which makes it difficult to impart stability to the foam. .
상기 난연재는 tris(2,3-dichloropropyl) 인산염(phosphate)을 사용하고, 인계화합물과의 분해, 탈수소, 탈수반응으로 탄화물이 형성되어 연소에 대한 방호막을 생성시키는 역할을 하는 것으로 2wt% 이상 첨가될 경우 난연 기능은 향상되나 발포체의 결합력을 떨어뜨리게 되며, 1wt% 미만 첨가시 난연 기능이 현저히 저하됨으로써 1~2wt% 범위내에서 첨가하는 것이 바람직하다.The flame retardant uses tris (2,3-dichloropropyl) phosphate, and carbides are formed by decomposition, dehydrogenation, and dehydration with a phosphorus compound, which serves to create a protective film against combustion. In this case, the flame retardant function is improved, but the bond strength of the foam is lowered, and when it is added below 1 wt%, the flame retardant function is significantly lowered, and therefore, it is preferable to add it within the range of 1 to 2 wt%.
상기 촉매는 옥테이트 배열(stannous octoate)의 주석을 함유하는 성분으로 수지반응을 촉진시키며 반응성의 상승효과를 가져오는 역할을 하는 것으로서 0.8wt% 이상을 넘어서면 수지화 반응이 너무 빨라 폼 셀벽이 지나치게 강해지므로서 밀폐셀(closed cell)이 많아져 수축이 생기는 문제점이 있으며, 0.2wt% 미만 첨가시 수지반응의 촉진 저하를 가져오게 되어 0.2~0.8wt% 범위내에서 첨가하는 것이 바람직하다.The catalyst is a tin-containing component of stannous octoate, which promotes the resin reaction and has a synergistic effect on the reactivity. When the catalyst exceeds 0.8wt%, the resination reaction is too fast and the foam cell wall is excessive. As it becomes stronger, there is a problem that shrinkage occurs due to the increase of closed cells, and when it is added less than 0.2 wt%, it is preferable to add within the range of 0.2 to 0.8 wt%.
상기 물은 제 1 프리폴리머와 반응시 이산화탄소(CO2) 가스를 방출시켜 발포를 생성하는 것으로 0.8wt% 이상 첨가시 발포된 폼이 부스러지는 현상이 발생할 수 있고 이는 접착력 저하의 원인이 되며, 0.2wt% 미만 첨가시 발포가 원할히 이루어지지 못하는 문제점이 발생되어 0.2~0.8wt% 범위내에서 첨가하는 것이 바람직하다.When the water reacts with the first prepolymer, carbon dioxide (CO2) gas is released to generate foam, and when 0.8 wt% or more is added, the foam may collapse. This may cause deterioration of adhesion force. When the addition is less than the foaming does not occur smoothly occurs it is preferable to add within the range of 0.2 ~ 0.8wt%.
이와 같은 성분으로 이루어진 제 1 수지용액의 제조과정은 분자량 400의 폴리올 71~80wt%와, 분자량 600의 폴리올 17~24wt%와, 실리콘 정포제 1~2wt%와, 난연제 1~2wt%와, 촉매 0.2~0.8wt%와, 물 0.2~0.8wt%을 반응조에 투입하여 200~300rpm속도로서 약 20~30분간 교반하여 완성한다.The manufacturing process of the first resin solution composed of such components is 71-80 wt% of a polyol having a molecular weight of 400, 17-24 wt% of a polyol having a molecular weight of 600, 1-2 wt% of a silicon foam stabilizer, 1-2 wt% of a flame retardant, and a catalyst. 0.2-0.8 wt% and 0.2-0.8 wt% of water are added to the reactor and stirred for about 20-30 minutes at 200-300 rpm.
또한, 방수.방음제 기능을 갖고 초속 경화형 폴리우레아를 구성하는 제 2 프리폴리머은 13~17% NCO 메틸렌 디이소시아네이트 100wt%로 이루어진 것으로서, 상기 메틸렌 디이소시아네이트는 전체 경도와 내후성, 신장율 등 물성을 좌우하는 재료로 N=C=O결합(이하 'NCO'라함)을 사용하였으며, NCO 함유량이 높아질수록 경화 후 도막의 경도는 높아지고, NCO 함유량이 낮아질수록 경화 후 도막의 경도는 낮아지는 것으로서, 이러한 NCO 함유량은 본 발명에서는 13~17% NCO 메틸렌 디이소시아네이트를 사용하는 것이 바람직하다.In addition, the second prepolymer having a waterproof and soundproofing function and constituting the ultra-fast curing polyurea is composed of 100 wt% of 13-17% NCO methylene diisocyanate, and the methylene diisocyanate is a material that influences physical properties such as overall hardness, weather resistance, and elongation rate. N = C = O bond (hereinafter referred to as 'NCO') was used, and the higher the NCO content, the higher the hardness of the coating after curing, and the lower the NCO content, the lower the hardness of the coating after curing. In the invention, it is preferable to use 13-17% NCO methylene diisocyanate.
그리고 초속 경화형 폴리우레아를 구성하는 제 2 수지용액은 방수.방음제의 신장율과 인장강도를 조절하기 위한 폴리옥시프로필렌디아민(polyoxypropylene- diamine) 40~55wt%와, 경화시간을 조정하기 위한 분자량 5,000의 폴리에테르트리아민(polyethertriamine) 4~11wt%와, 각 성분들의 가교반응을 증가시켜 주기 위해 첨가제로 사용되는 디에틸톨루엔디아민(Polydiethyltoluenediamine) 4~6wt%와, 경화 물성 중 겔화 시간 즉, 경화시간을 조정하고 신율을 증가시켜 주는 폴리디페닐트리아민(Polydiphenyltriamine) 16~24wt%와, 색상을 나타내기 위한 안료(pigment) 3~4 wt%와, 방수.방음제의 내마모성 향상시키는 나노(Nano) 입자의 제 1 충진재 1~2wt%와, 상기 원료간의 혼합을 원활하게 시켜주고 도포시 소지와의 접착력을 증가시켜 주는 접착증진제 1~2wt%와, 방음성 향상을 위해 첨가되는 나노(Nano) 입자의 제 2 충진재 6~8wt%로 이루어진다.The second resin solution constituting the ultra-fast curing polyurea is 40 to 55 wt% of polyoxypropylene-diamine for adjusting the elongation and tensile strength of the waterproof and soundproofing agent, and a polyolefin having a molecular weight of 5,000 to adjust the curing time. 4 ~ 11wt% of ethertriamine, 4 ~ 6wt% of polydiethyltoluenediamine used as an additive to increase the crosslinking reaction of each component, and the gelation time of the curing properties 16 ~ 24 wt% of polydiphenyltriamine, 3 ~ 4 wt% of pigment to express color, and nano particles which improve the wear resistance of waterproof and soundproofing agents. 1 1 ~ 2wt% of filler and 1 ~ 2wt% of adhesion enhancer which smoothly mixes the above raw materials and increase the adhesion to the base when applied, and Nano added to improve sound insulation 'S second filler consists of a 6 ~ 8wt%.
여기서, 신장율과 인장강도를 조절하기 위한 상기 폴리옥시프로필렌디아민은 40wt% 미만 첨가시 도막의 신장율이 현저히 떨어지고, 55wt% 이상 초과하여 첨가하면 신장율과 인장강도가 증가하지만 내마모성이 떨어져 쉽게 파괴됨으로써 작업의 특성상 40~55wt% 범위내에서 혼합하는 것이 바람직하다.Here, the polyoxypropylene diamine for controlling the elongation rate and tensile strength is significantly lower the elongation rate of the coating film when added below 40wt%, and when added above 55wt%, the elongation rate and tensile strength are increased, but wear resistance is easily broken by being broken. It is preferable to mix within the range of 40-55 wt% for the characteristic.
상기 경화시간을 조정하기 위한 분자량 5,000의 폴리에테르트리아민은 4wt% 미만으로 혼합될 경우 경화시간이 늦어져 작업성이 저하되고, 11wt% 초과 적용 시 경화시간이 너무 빠르게 되어 콘크리트 바닥면과의 부착력이 저하됨으로써 4~11wt% 범위내에서 혼합하는 것이 바람직하다.Polyethertriamine having a molecular weight of 5,000 to adjust the curing time is less than 4wt% when the curing time is slow workability is lowered, when applied more than 11wt% curing time is too fast adhesion to the concrete floor surface It is preferable to mix in 4-11 wt% of ranges by this being reduced.

Since an effect cannot be obtained, it is preferable to mix in the range of 6-8 wt%.
