Description
본 발명은 탄성이 강하고 내마모성, 내약품성, 내노화성을 갖는 우레탄 방수몰타르 제조방법에 관한 것으로서, 더욱 상세하게는 우레탄 수지와 모래로 이루어진 방수 몰타르 또는 우레탄수지, 모래, 유리 섬유봉, 탄소 섬유봉 등으로 이루어진 방수 몰타르를 제조하여 균열된 건축구조물, 신축건물의 방수제로 사용할 수 있도록 함으로서 시공이 간단 용이하고 방수가 완벽한 방수몰타르 제조방법 및 건축부재에 관한 것이다. The present invention relates to a urethane waterproof mortar manufacturing method having a strong elasticity, wear resistance, chemical resistance, aging resistance, more specifically, waterproof mortar or urethane resin made of urethane resin and sand, sand, glass fiber rods, carbon fiber rods, etc. The present invention relates to a method for manufacturing a waterproofing mortar and a building member, which is simple and easy to construct and perfect for waterproofing, by manufacturing a waterproof mortar made of cracks to be used as a waterproofing agent for a cracked building structure or a new building.
종래에는 사용중인 콘크리트 건축구조에 균열이 발생하여 보수작업을 할 경우 시멘트와 모래, 물을 혼합한 몰타르를 사용하거나 시멘트와 물을 혼합한 시멘트 풀을 사용하였으나 몰타르의 경우 파손된 부분의 공간부를 메우는 용으로는 가능하나 균열이 된 부분 또는 슬래브의 방수처리로는 불가능할 뿐만 아니라 기존의 구조물과 접합이 잘 이루어지지 않는 문제점이 있으며, 시멘트 풀의 경우 균열된 부분의 메움 작업은 어느 정도 효과를 볼 수 있으나 이 역시 기존의 구조물과 시멘트 풀의 양생 후 강도의 차이에 의하여 접합부가 균열되는 문제점이 있었다.Conventionally, when repairing due to cracks in the concrete building structure being used, mortar mixed with cement, sand, and water was used or cement paste mixed with cement and water was used. Although it is possible to use it, but it is not possible to waterproof the cracked part or the slab, and there is a problem that it is difficult to join the existing structure.In the case of cement paste, filling the cracked part may have some effect. However, this also had a problem in that the joint cracks due to the difference in strength after curing of the existing structure and cement paste.
상기의 방법 이외로는 합성수지 실리콘을 주입하여 균열부분을 보수하는 경우가 있으나 이는 보수공사 초기에는 완벽한 접합이 이루어지나 외기의 온도에 약하므로 시간이 지날 수록 점성이 떨어져 재시공해야 하는 문제점 등이 있었다. In addition to the above method, the cracks may be repaired by injecting synthetic resin, but this may be a perfect joint at the beginning of repair work, but it may be weak in the temperature of the outside air, and thus, the viscosity may have to be rebuilt over time.
또한 기존의 다른 예로는 도로시공시 지반침하를 방지하기 위한 방수시트로서 산업폐기물인 폴리우레탄 폼을 재생처리 하여 폴리우레탄쉬트를 얻고 이 쉬트에 고무화아스팔트를 접착하여 고무화아스팔트층을 형성한 다음 그 위에 이 형 필름을 적층시킨 폴리우레탄 방수적층 쉬트가 있었으나, 이러한 종래의 폴리우레탄 방수적층 쉬트는 아스팔트의 온도변화에 따른 상태의 변화 즉 점도의 변화 때문에 장기간이 경과하면 점성이 없어져 경화되고 경화된 아스팔트 층은 온도변화에 따라 팽창과 수축이 되풀이되는 과정에서 접착성이 극히 불량한 폴리에치렌필름층 사이에 간극을 발생시키고 또 박막의 폴리에치렌필름은 시공전의 작업 부주의 몰탈시공시 돌이나 이물질이 혼입되면 표면손상이 쉽게 올 수 있으므로 간극과 필름의 파손은 방수기능을 저하시킨다.In addition, another existing example is a waterproof sheet for preventing ground subsidence during road construction to obtain a polyurethane sheet by recycling polyurethane foam, which is an industrial waste, and to form a rubberized asphalt layer by adhering rubberized asphalt to the sheet. Although there was a polyurethane waterproof laminated sheet in which the mold film was laminated thereon, such a conventional polyurethane waterproof laminated sheet had a viscous property after a long period of time due to the change of state according to the temperature change of asphalt, that is, the viscosity, so that the cured and cured asphalt In the process of repeated expansion and contraction due to temperature change, the layer generates gaps between the layers of polyethylene films which are extremely poor in adhesion, and the polyethylene films of thin films are mixed with stones or foreign substances during mortality during careless work before construction. Surface damage can easily occur. Lowers.
또한 이와 같은 방수쉬트는 쉬트 접착후 그 위에 필히 몰탈 시공이 있어야 하는바 바닥 방수시공시는 몰탈시공작업이 용이하나 벽면 방수시공시는 미끄러운 포리에치렌의 표면 때문에 벽돌을 쌓거나 거푸집을 설치해야 하는 등 시공작업이 극히 번거운 문제점이 있었다.In addition, such a waterproof sheet must be mortar-coated on top of the sheet after bonding. It is easy to mortar the floor during waterproofing, but when waterproofing the wall, it is necessary to stack bricks or form the mold due to the slippery surface of poriethiene. Such construction work was extremely troublesome.
본 발명은 이와 같은 문제점을 감안한 것으로서, 우레탄 수지와 모래 및 CO2가스를 혼합하여 우레탄 방수 몰타르를 제공하여 콘크리트 구조물의 방수와 보수공사및 방수공사를 간단 용이하게 시공하고 보수 관리비용을 최소화 할 수 있도록 함을 목적으로 한 것이다.In view of the above problems, the present invention provides a urethane waterproofing mortar by mixing urethane resin with sand and CO 2 gas, thereby easily and easily constructing and repairing a concrete structure, and waterproofing and minimizing maintenance and management costs. It is for the purpose of making it possible

The present invention having the above object can be applied by spraying a composite urethane resin, sand, etc. with a nozzle between a glass fiber rod or a carbon fiber rod, or spraying a waterproof mortar made of urethane resin and sand with a nozzle. It is characterized by providing a urethane waterproof mortar or building member having a strong elasticity, wear resistance, chemical resistance, aging resistance by molding the building member by filling in.

MDI 50중량%와 분자량 2,000∼4,000g/mol의 폴리올 50중량%가 혼합된 우레탄 A제와, 다염기성 폴리올 혼합물 80중량%, 아민류 3.0중량%, 피그먼트 10중량%, 첨가제7.0중량%를 혼합한 우레탄 B제를 1:1로 혼합한 복합 우레탄 50 중량%, 모래 30중량%, CO2 20중량%로 혼합 분사시켜 패널(11)또는 블록(12)을 형성한 건축부재(10)를 특징으로 한다.50% by weight of MDI and 50% by weight of polyol having a molecular weight of 2,000 to 4,000 g / mol are mixed with the urethane A agent, 80% by weight of a polybasic polyol mixture, 3.0% by weight of amines, 10% by weight of pigment, and 7.0% by weight of additive. Characterized by the building member 10 in which the panel 11 or the block 12 was formed by mixing and spraying a mixture of 50% by weight, 30% by weight of sand, 20% by weight of CO 2 , and a mixture of 1 urethane B in a 1: 1 ratio.

또한 상기 복합 우레탄 50 중량%, 모래 30중량%, CO2 20중량%로 혼합된 패널(11) 중앙부에 유리 섬유봉(13)을 井형으로 설치한 것을 특징으로 한다.In addition, the glass fiber rod 13 is installed in the center portion of the panel 11 mixed with 50 wt% of the composite urethane, 30 wt% of sand, and 20 wt% of CO 2 .
이와 같이 구성된 본 발명은 복합 우레탄과 모래를 혼합하거나 또는 복합 우레탄만을 사용하여 방수 몰타르 또는 건축부재로 성형하게 되는데 이때 반드시 CO2를 혼합하여 발포하여 사용한다. In the present invention configured as described above, the composite urethane and sand are mixed or molded into a waterproof mortar or a building member using only the composite urethane. In this case, CO 2 must be mixed and foamed.
본 발명은 기존의 우레탄에 가스를 주입하여 발포된 우레탄과는 상이한 구성을 갖는 것입니다.The present invention is different from the urethane foamed by injecting gas into the existing urethane.
즉, 기존에는 통상적인 우레탄에 경화제와 가스를 주입하여 분사 발포하는 방식으로 식내장시 조형물 등을 만들었으나 이러한 발포 우레탄은 신축성이 전혀 없는 상태이기 때문에 외부의 충격에 쉽게 파손 되는 반면에 본 발명에서 사용되는 복합 우레탄은 강한 접착력과 탄성을 갖고 내마모성, 내약품성, 내노화성을 갖는 도록 하기 위해 MDI 50중량%와 분자량 2,000∼4,000g/mol의 폴리올 50중량%가 혼합된 프리폴리머 우레탄과, 다염기성 폴리올 혼합물 80중량%, 아민류 3.0중량%, 피그먼트 10중량%, 첨가제 7.0중량%를 혼합한 우레탄을 1:1로 혼합하는 복합 우레탄을 제조하였다.That is, in the past, moldings and the like were made by injecting a curing agent and a gas into a conventional urethane by injection foaming, but since the foamed urethane is not in a state of elasticity at all, it is easily damaged by external shocks, while in the present invention The composite urethane used is a prepolymer urethane in which 50% by weight of MDI and 50% by weight of polyol having a molecular weight of 2,000 to 4,000 g / mol are mixed in order to have strong adhesion and elasticity, and to have abrasion resistance, chemical resistance, and aging resistance, and polybasic polyol The composite urethane which mixed the urethane which mixed 80 weight% of mixtures, 3.0 weight% of amines, 10 weight% of pigments, and 7.0 weight% of additives by 1: 1 was prepared.

이를 좀더 구체적으로 살펴보면, 폴리올을 크게 두 가지로 나누면 polyether polyol과 polyester polyol로 나눌 수 있는데 최근에는 80~90%정도로 주로 polyether polyol이 많이 쓰여지고 있다. 또한 polyether polyol은 알칼리 촉매하에서 에틸렌 옥사이드와 프로필렌 옥사이드를 중합시켜 만든다. 개시제로서는 낮은 분자량의 di,polyfunctional 알코올 또는 아민이 사용된다. In more detail, the polyol can be divided into two broadly divided into polyether polyol and polyester polyol. Recently, the polyether polyol is mainly used as 80 ~ 90%. Polyether polyols are also made by polymerizing ethylene oxide and propylene oxide under alkali catalysts. As the initiator, low molecular weight di, polyfunctional alcohols or amines are used.
Polyester polyol의 경우에는 di,polycarboxylic acid를 축중합하거나 이들의 anhydride와 di,polyalcohol를 축중합해서 얻는다. 가장 일반적인 polyester polyol은 Adipic acid또는 phthalic anhydride와 탄소 2~6개 정도 포함하고 있는 Diglycol과 같은 oligoether diols또는 glycerol또는 trimethylol propane과 같은 triols과의 반응으로 얻어지며 elastomers나 연질폼, 경질폼 등에 많이 쓰인다. Polyester polyols are obtained by polycondensation of di, polycarboxylic acids or condensation of anhydrides with di, polyalcohols. The most common polyester polyols are obtained by reaction with oligoether diols such as adipic acid or phthalic anhydride and diglycol containing 2 to 6 carbon atoms, or triols such as glycerol or trimethylol propane, and are widely used in elastomers, soft foams and rigid foams.
Polyether polyol은 상대적으로 점도 편차가 적게 생산 할 수 있습니다. 폴리머 폴리올은 polyether polyol에 solid가 분산되어 있는 것을 말하며, 폼의 경도를 높이는데 사용된다.Polyether polyols can produce relatively low viscosity variations. Polymer polyols are solids dispersed in polyether polyols and are used to increase the hardness of foams.
따라서 본 발명은 MDI 50중량%와 분자량 2,000∼4,000g/mol의 폴리올 50중량%를 교반 혼합하여 프리폴리머를 제조하고, 프리폴리머 제조시 반응속도에 주의하면서 100∼200RPM으로 MDI를 교반하는 동시에 온도 45℃에서 폴리올(polyol)을 서서히 주입하여 우레탄 A제를 제조하게 된다.Therefore, the present invention is prepared by preparing a prepolymer by stirring and mixing 50% by weight of MDI and 50% by weight of polyol having a molecular weight of 2,000 to 4,000 g / mol, and while stirring the MDI at 100 to 200 RPM while paying attention to the reaction rate when preparing the prepolymer, the temperature is 45 ° C. Injecting a polyol (polyol) slowly to prepare a urethane A.
제2공정: 우레탄 B제 제조Second Step: Manufacture of Urethane B

The pigment (pigment) is the English mark of the pigment, is an inorganic system is not bleached by ultraviolet light, the color is not limited to any one color because the color depends on the site conditions.
제3공정: 복합 우레탄제조3rd step: composite urethane
상기 우레탄 A제와 우레탄 B제를 각각 제조한 후에는 A와 B의 우레탄 비율이 1:1로 혼합되도록 하여 복합 우레탄을 제조하게 된다.After the urethane A agent and the urethane B agent are respectively prepared, the urethane ratio of A and B is mixed in a ratio of 1: 1 to prepare a composite urethane.
상기 제1공정과 제2공정에서 제조된 A,B제 우레탄과 이를 혼합하여 제조된 복합우레탄은 모두 액체(수지)과정에서 실시된다.The A and B urethanes prepared in the first step and the second step and the composite urethane prepared by mixing them are all carried out in a liquid (resin) process.
