Abstract
Description
본 발명은 불소 변성 타르우레탄 도막방수재 및 그 제조 방법, 불소 변성 타르우레탄 도막방수재를 이용한 방수 시공 방법에 관한 것으로, 자세하게는 슬라브 상면에 비노출공법으로 방수층을 형성시 방수시트층 하부와 슬라브간을 새롭게 개발된 불소 변성 타르우레탄 도막방수재를 이용하여 전면밀착식으로 시공하는 방법과 여기에 사용되는 불소변성 타르우레탄과 그 제조방법에 관한 것이다.
The present invention relates to a fluorine-modified tar urethane coating waterproofing material and a method of manufacturing the same, and a waterproofing method using the fluorine-modified tarethane coating waterproofing material. The present invention relates to a method of constructing in close contact with the developed fluorine-modified tar urethane coating waterproofing material, and to a method of producing the fluorine-modified tar urethane used therein.
토목 및 건축용으로서의 폴리우레탄 소재는 1980년대 초기에 도입되었다. 폴리우레탄 소재는 소재 자체로서의 특징인 이음새 없는 시공이 가능하고 복잡한 형태의 구조물에 대해 잘 순응하는 시공 상의 특성과 소지면과의 접착성, 내약품성, 내구성과 같은 화학적인 특성과 흡음성, 치수 안정성과 같은 물리적인 성질이 뛰어나며, 특히 신장율이 우수하다는 큰 장점 때문에 하지 균열에 대한 추종성이 뛰어나 건축물의 내, 외벽 및 바닥 방수재로서 그 수요가 증대되고 있다. Polyurethane materials for civil and building use were introduced in the early 1980s. Polyurethane material is capable of seamless construction, which is a characteristic of the material itself, and chemical properties such as construction properties, adhesion to a small surface, chemical resistance, durability, and sound absorption, and dimensional stability, which are well conformed to complex structures. Due to its great physical properties, especially its excellent elongation, it has excellent trackability against cracking under the ground, increasing the demand for waterproofing the interior, exterior walls and floors of buildings.
그러나 현재 이처럼 건축용으로 우수한 특성을 가지는 폴리우레탄 소재는 생산 공장에서 이소시아네이트 프리폴리머와 폴리올 혼합물로 구분하여 생산하며 이를 시공 현장에서 정해진 배합비에 따라 계량, 배합, 교반, 시공의 여러 단계를 거쳐 시공해야 하므로 시공 상의 결함이 생기기 쉽고 숙련된 전문 인력을 필요로 하므로 인건비 상승의 원인이 되며 이는 전체적으로 시공비를 상승시켜 시공 효율을 감소시킨다는 문제가 단점으로 지적되기도 한다.
However, at present, polyurethane materials having such excellent characteristics for construction are produced by isocyanate prepolymer and polyol mixture in the production plant, and they must be constructed through several steps of weighing, blending, stirring, and construction according to the mixing ratio determined at the construction site. Since defects in the tops are likely to occur and skilled professionals are required, it is a cause of increase in labor costs, which in turn increases the construction cost and reduces the construction efficiency.
통상 2액형 폴리우레탄 소재는 한정된 시간 내에 교반된 방수재를 모두 사용해야 하므로 교반과 시공의 시간 간격을 잘 조절해야 하고 이 시간이 맞지 않을 경우 재료의 손실량이 많아진다. In general, two-component polyurethane materials have to use all of the waterproofing material that is stirred within a limited time, so the time interval between stirring and construction must be well controlled, and the amount of material loss is increased when this time is not correct.
따라서 이러한 폴리우레탄 소재의 우수한 물리, 화학적 특성을 유지시키며 2액형으로서의 단점을 보완하기 위해 폴리우레탄 건축용 소재의 1액형화가 연구되고 있다. 예를 들어 이소시아네이트(NCO) 중량% 함량을 1 - 5% 정도의 이소시아네이트 프리폴리머를 합성하고 여기에 충전제, 안정제, 착색제 등을 첨가하여 폴리우레탄 소재를 1액형화 하는 방법을 사용하고 있다. Therefore, in order to maintain the excellent physical and chemical properties of these polyurethane materials and to compensate for the shortcomings as a two-component type, one-component formulation of polyurethane building materials has been studied. For example, a method of synthesizing an isocyanate prepolymer having a content of 1% to 5% by weight of isocyanate (NCO) and adding a filler, a stabilizer, a colorant, and the like is used to form a one-component polyurethane material.
그러나 이러한 방법은 상온에서 경화 시간이 늦고 약간의 수분만 존재해도 저장 안정성이 저하되며 수분과 이소시아네이트가 반응하여 생성되는 이산화탄소에 의하여 도막의 부풀음 하자가 발생하기 쉽다는 단점이 있다.
However, this method has a disadvantage in that the curing time is slow at room temperature and only a little moisture is present, and storage stability is deteriorated, and swelling defects of the coating film are easily generated by carbon dioxide generated by the reaction of water and isocyanate.
이러한 단점을 보완하기 위해 일본 특허 공고 공보 제5-75035호에는 모포리노 디에틸 에테르를 촉매를 사용하여 저장 안정성 및 경화 속도를 개선하는 방법이 개시되어 있다. To compensate for this disadvantage, Japanese Patent Publication No. 5-75035 discloses a method of improving storage stability and curing rate by using a catalyst of morpholino diethyl ether.
그러나 이러한 방법은 이산화탄소에 의한 도막의 부풀음 현상이 일어나는 하자 발생을 해결하지는 못하였다.
However, this method did not solve the occurrence of defects caused by swelling of the coating film caused by carbon dioxide.
따라서, 이러한 문제점을 해결하기 위하여 미합중국 특허 제4720535호 또는 일본 특허 공개 공고 제4-226522호에는 잠재성 경화제인 시프 베이스를 이용하는 방법이 제시되어 있다. 즉, 1차의 디 또는 트리 아민에 알데히드를 반응시켜 폴리알디민을 만들고 이를 이소시아네이트 프리폴리머와 혼합하여 1액형 소재로 사용하는 방법이다.Therefore, in order to solve this problem, US Patent No. 4720535 or Japanese Patent Laid-Open Publication No. 4-226522 discloses a method using a seed base which is a latent curing agent. In other words, aldehyde is reacted with primary di or tri amine to make poly aldimine, which is mixed with an isocyanate prepolymer and used as a one-component material.
그러나 이와 같은 폴리알디민을 이소시아네이트와 혼합하여 1액형 우레탄 소재로 사용할 경우 고온 다습한 환경에서는 반응성이 빨라 하절기 건물 옥상 방수 시에는 부적당한 문제점이 있다. 즉, 표면 및 도막 밑부분의 경화는 쉽게 진행되지만 도막 내부는 경화된 도막 표면으로부터의 습기 침투가 어려워 경화 진행 속도가 느리며 경화 중 해리되는 알데히드에 의한 부풀음 하자가 자주 발생된다.
However, when the poly-aldimine is mixed with an isocyanate and used as a one-component urethane material, the reactivity is fast in a high temperature and high humidity environment. That is, the hardening of the surface and the bottom of the coating proceeds easily, but the inside of the coating is difficult to penetrate moisture from the hardened coating surface, so that the curing progress is slow and swelling defects are frequently caused by aldehydes dissociated during curing.
잠재성 경화제를 이용하는 또 다른 방법으로 영국 특허 제1575666호에서는 2차 아민에 케톤 또는 알데히드를 반응시켜 폴리 엔아민을 만들고 이것을 이소시아네이트 프리폴리머와 혼합하여 1액형화하는 방법을 제시하였다. Another method using latent curing agents is described in British Patent No. 1575666, which reacts a ketone or an aldehyde with a secondary amine to form a polyenamine, which is then mixed with an isocyanate prepolymer to form one part.
그러나 이러한 경우에는 프리폴리머의 이소시아네이트를 마스킹 시켜 주거나 반응성이 아주 낮은 이소시아네이트를 사용하여야 하며 저장 안정성이 낮아 건축용 소재로서 사용하기 어려운 단점이 있다.
In this case, however, the isocyanate of the prepolymer must be masked or an isocyanate having a very low reactivity should be used, and it is difficult to use as a building material because of low storage stability.
또한 한국특허 10-0192201에서는 잠재성 경화제 사슬에 알디민과 케티민이 동시 존재하게 하여 경화 속도를 조절하여 하자 발생율이 낮고 하절기와 같은 고온 다습한 불리한 환경 조건하에서도 시공이 가능하다고 하였으나 상기의 다른 특허와 마찬가지의 문제점을 내포하고 있다. 또한 대한민국특허 10-0884015에는 접착제층--> 통기완층 엠보싱 폴리비닐클로라이드시트층--> 우레탄 방수층--> 탑코트층으로 구성된 노출형 복합방수 구조에 대하여 나와 있는데, 이처럼 우레탄 도막방수제 시공 전에 시트층을 형성 시키게 되면 폴리우레탄에 포함된 용제가 폴리비닐클로라이드 시트층에 서서히 흡수가 되어 시트가 수축되는 현상이 발생하며, 또한 엠보싱 시트의 엠보싱 면이 바닥에 위치하기 때문에 물의 통로 역할을 하게 되어 누수 현상이 발생하게 되면 시공 전면을 걷어내야 하는 문제점을 가지고 있다.
In addition, in Korean Patent 10-0192201, aldimine and ketamine are simultaneously present in the latent curing agent chain to control the curing rate, so that the defect rate is low and the construction is possible under adverse environmental conditions such as high temperature and high humidity in summer. The same problem is involved. In addition, Korean Patent No. 10-0884015 discloses an exposed composite waterproof structure composed of an adhesive layer-> aeration layer embossed polyvinyl chloride sheet layer-> urethane waterproof layer-> top coat layer. When the sheet layer is formed, the solvent contained in the polyurethane is gradually absorbed by the polyvinyl chloride sheet layer, causing the sheet to shrink. Also, since the embossed surface of the embossed sheet is located at the bottom, it acts as a water passage. If a leak occurs, the front of the construction has a problem that needs to be rolled out.

이하 본 발명의 실시 예인 구성과 그 작용을 첨부도면에 연계시켜 상세히 설명하면 다음과 같다. 또한 본 발명을 설명함에 있어서, 관련된 공지기능 혹은 구성에 대한 구체적인 설명이 본 발명의 요지를 불필요하게 흐릴 수 있다고 판단되는 경우 그 상세한 설명은 생략한다.
Hereinafter, the configuration and the operation of the embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.
본 발명의 불소 변성 타르우레탄도막방수재의 제조방법은 2,2,4-트리메틸-1,6-헥사메틸렌디이소시아네이트 말단 폴리우레탄 프리폴리머 35.3 ~ 40.1 wt%, 2-(퍼플로로옥틸)에탄올 5.5 ~ 6.4wt%, 2-(퍼플로로데실)에탄올 15.5 ~ 17.8wt%, 2,2-비스(4-하이드록시페닐)헥사플로로프로판 16.3 ~ 19.8wt% 및 타르 21.8 ~ 27.3wt%를 혼합하여 불소 변성 타르우레탄을 제조하는 단계와;Fluorine-modified tar urethane coating waterproofing material of the present invention is 2,2,4-trimethyl-1,6-hexamethylene diisocyanate terminated polyurethane prepolymer 35.3 ~ 40.1 wt%, 2- (perfluorooctyl) ethanol 5.5 ~ 6.4 wt%, 15.5 to 17.8 wt% of 2- (perfluorodecyl) ethanol, 16.3 to 19.8 wt% of 2,2-bis (4-hydroxyphenyl) hexafluoropropane and 21.8 to 27.3 wt% of tar Preparing a fluorine-modified tar urethane;
상기 단계에 따라 제조된 불소 변성 타르우레탄 55.7 ~ 65.7wt%, 폴리에틸렌칩 33.0 ~ 43.6wt%, 폴리옥시에틸렌에틸이써모노올레이트하이드로카본 0.3 ~ 1.1wt% 및 폴리옥시에틸렌알킬이써썩시닉 0.3 ~ 1.1 wt%를 혼합하여 균일하게 분산시켜 도막방수재를 제조하는 단계로 이루어진다.
Fluorine-modified tar urethane prepared according to the above step 55.7 ~ 65.7wt%, polyethylene chip 33.0 ~ 43.6wt%, polyoxyethylene ethyl thermomonohydrohydrocarbon 0.3 ~ 1.1wt% and polyoxyethylene alkyl thermoseptic 0.3 ~ 1.1 wt% of the mixture is uniformly dispersed to prepare a waterproof film.
상기 불소 변성 타르우레탄 제조단계는 혼합 조성된 원료를 50 ~ 60℃에서 3 ~ 4시간 반응시켜 고형분 95%의 불소 변성 타르우레탄을 제조한다. 여기서 불소 변성 타르우레탄 조성물을 50 ~ 60℃에서 3 ~ 4시간 반응시키는 이유는 온도가 50 ℃보다 낮으면 불소 화합물들과 이소시아네이트와의 반응성이 떨어지고, 60℃보다 높으면 급격하게 반응하여 점도가 상승하는 문제점이 있기 때문이다. In the fluorine-modified tar urethane production step, the mixed raw material is reacted at 50 to 60 ° C. for 3 to 4 hours to prepare a fluorine-modified tar urethane having a solid content of 95%. Here, the reason why the fluorine-modified tar urethane composition is reacted at 50 to 60 ° C. for 3 to 4 hours is that when the temperature is lower than 50 ° C., the reactivity between the fluorine compounds and the isocyanate is lowered. Because there is a problem.
또한 반응시간을 3시간 보다 적게 반응시키면 미반응 물질이 존재하여 완제품의 성능을 저하 시키는 문제점이 있고, 4시간 보다 많이 반응시키면 분자량이 증가하여 유동성이 저하하는 문제점이 있기 때문이다.
In addition, when the reaction time is less than 3 hours, there is a problem in that the unreacted substance is present to reduce the performance of the finished product, and when the reaction time is more than 4 hours, there is a problem that the fluidity decreases due to an increase in molecular weight.
상기 불소 변성 타르우레탄 조성물에서, 2,2,4-트리메틸-1,6-헥사메틸렌디이소시아네이트 말단 폴리우레탄 프리폴리머는 이소시아네이트(NCO) INDEX가 2.0 ~ 2.8이고 이론 이소시아네이트(NCO) 중량%가 14~15 범위에서 제조한 무게평균분자량이 50000 ~ 60000인 것을 전체 조성물 중에서 35.3 ~ 40.1wt%가 되도록 조성하는데, 이와 같이 조성한 이유는 35.3wt% 보다 작으면 분자량이 작아 인장강도와 신장율이 감소하는 문제점이 있고, 40.1wt% 보다 많으면 반응중 점도가 급격히 상승하여 생산 하기가 힘든 문제점이 있기 때문이다.In the fluorine-modified tar urethane composition, 2,2,4-trimethyl-1,6-hexamethylene diisocyanate terminated polyurethane prepolymer has an isocyanate (NCO) INDEX of 2.0 to 2.8 and a theoretical isocyanate (NCO) weight percent of 14 to 15 The weight average molecular weight prepared in the range is 50000 ~ 60000 to be 35.3 ~ 40.1wt% of the total composition, the reason for the composition is less than 35.3wt% has a problem in that the tensile strength and elongation decreases because the molecular weight is small If it is more than 40.1wt%, the viscosity increases rapidly during the reaction, which is difficult to produce.
또한 상기 2-(퍼플로로옥틸)에탄올 함량이 5.5wt% 보다 미만이면 프리폴리머에 잔류 이소시아네이트기가 존재하여 시공시 수분과 반응하여 부풀음 현상이 발생할수 있으며, 또한 6.4wt% 보다 많으면 프리폴리머의 점도가 높아 도막방수제를 제조하기가 힘들기 때문이다. In addition, when the 2- (perfluorooctyl) ethanol content is less than 5.5 wt%, residual isocyanate groups are present in the prepolymer, which may cause swelling by reacting with moisture during construction, and when the amount is higher than 6.4 wt%, the viscosity of the prepolymer is high. This is because it is difficult to manufacture a film waterproofing agent.
또한 상기 2-(퍼플로로데실)에탄올 함량이 15.5wt% 보다 미만이면 프리폴리머에 잔류 이소시아네이트기가 존재하여 시공시 수분과 반응하여 부풀음 현상이 발생할수 있으며, 또한 17.8 wt% 보다 많으면 프리폴리머의 점도가 높아 도막방수제를 제조하기가 힘들기 때문이다. In addition, when the content of 2- (perfluorodecyl) ethanol is less than 15.5 wt%, residual isocyanate groups may be present in the prepolymer, which may cause swelling by reacting with moisture during construction.In addition, when the amount is higher than 17.8 wt%, the viscosity of the prepolymer is high. This is because it is difficult to manufacture a film waterproofing agent.
여기서 2-(퍼플로로옥틸)에탄올은 분자량 464, 비중 1.70, 녹는점 42 ~ 44℃, 끊는점 95 ~ 105℃인 것이 바람직하다. 또한 2-(퍼플로로데실)에탄올은 분자량 564, 비중 1.71, 녹는점 92 ~ 93℃, 끊는점 111 ~ 115℃인 것이 바람직 하다. It is preferable that 2- (perfluorooctyl) ethanol is molecular weight 464, specific gravity 1.70, melting | fusing point 42-44 degreeC, and breaking point 95-105 degreeC. Moreover, it is preferable that 2- (perfluorodecyl) ethanol is molecular weight 564, specific gravity 1.71, melting | fusing point 92-93 degreeC, and breaking point 111-115 degreeC.
2,2-비스(4-하이드록시페닐)헥사플로로프로판 16.3 ~ 19.8wt%의 수치한정 이유는 16.3wt% 이하이면 타르와 균일한 혼합이 되지 않고 19.8wt% 이상이면 과분산이 일어나 점도가 감소하는 문제가 발생된다The reason for the numerical limitation of 16.3 to 19.8 wt% of 2,2-bis (4-hydroxyphenyl) hexafluoropropane is that when it is 16.3 wt% or less, it is not uniformly mixed with tar. Problem occurs
여기서 2,2-비스(4-하이드록시페닐)헥사플로로프로판은 분자량 336, 녹는점 154 ~ 162℃인 것이 바람직하다. It is preferable that 2, 2-bis (4-hydroxyphenyl) hexafluoro propane is molecular weight 336, melting | fusing point 154-162 degreeC.
상기 타르 21.8 ~ 27.3wt%의 수치 한정이유는 21.8wt% 이하이면 경제성이 떨어지고 27.3wt% 이상이면 기계적 강도가 저하하는 문제가 있다.
The reason for limiting the numerical value of the tar 21.8 to 27.3 wt% is 21.8 wt% or less, and there is a problem that the economic strength is lowered.
상기와 같은 방법으로 제조한 고형분 95%의 불소 변성 타르우레탄 55.7 ~ 65.7wt%, 폴리에틸렌칩 33.0 ~ 43.6wt%, 폴리옥시에틸렌에틸이써모노올레이트하이드로카본 0.3 ~ 1.1wt% 및 폴리옥시에틸렌알킬이써썩시닉 0.3 ~ 1.1 wt% 를 균일 하게 혼합 하여 불소 변성 타르우레탄 도막방수재를 제조한다.
Fluorine-modified tar urethane 55.7-65.7 wt%, polyethylene chip 33.0-43.6 wt%, polyoxyethylene ethyl thermomonohydrohydrocarbon 0.3-1.1 wt%, and polyoxyethylene alkyl of 95% of the solid content prepared by the above method The fluorine-modified tar urethane coating waterproofing material is prepared by uniformly mixing 0.3-1.1 wt% of iseroxic.
상기와 같이 조성된 불소 변성 타르우레탄 도막방수재 중에서 불소 변성 타르우레탄의 수치 한정이유는 55.7wt% 보다 적게 사용하면 도막방수재의 전체적 물성이 감소하는 문제점이 있고, 65.7wt% 보다 많이 사용하면 단가가 상승하여 경제성이 떨어지는 문제점이 있기 때문이다.The reason for limiting the numerical value of the fluorine-modified tar urethane among the fluorine-modified tar urethane coating waterproofing materials formed as described above is that the overall physical properties of the coating-water repellent material decreases. This is because there is a problem that the economy falls.
상기 폴리에틸렌칩 33.0 ~ 43.6wt%의 수치 한정이유는 33.0wt%보다 적으면 내균열 추종성이 떨어지고, 43.6wt%보다 많으면 점도가 급상승하여 시공에 문제점이 있기 때문이다.The reason for limiting the numerical value of the polyethylene chip 33.0 ~ 43.6wt% is less than 33.0wt%, the crack tracking resistance is lowered, and more than 43.6wt%, there is a problem in construction due to the sharp rise in viscosity.
또한 폴리에틸렌칩은 규산소다가 코팅된 것으로 크기가 5 ~ 10mm인 것을 사용한다. In addition, polyethylene chips are coated with sodium silicate and use those having a size of 5 to 10 mm.
여기서 규산소다를 코팅한 이유는 타르우레탄 제조시 소량 포함되는 유기 용제에 녹는 현상을 방지하기 위함이다.The reason for coating the soda silicate is to prevent the phenomenon of melting in the organic solvent contained in a small amount during the production of tar urethane.
또한 크기를 한정한 이유는 5mm보다 작으면 시공시 도막 두께 확보가 어렵고10mm보다 크면 신장률이 저하하는 문제점이 있기 때문이다.
In addition, the reason for limiting the size is that it is difficult to secure the thickness of the coating film when the construction is smaller than 5mm, the elongation is lowered if it is larger than 10mm.
상기 폴리옥시에틸렌에틸이써모노올레이트하이드로카본과 폴리옥시에틸렌알킬이써썩시닉은 고형분 95%의 불소 변성 타르우레탄에 추가의 용제 사용 없이도 매우 높은 고형분 형태의 도막방수제를 제조할 수 있는 분산제로서 폴리옥시에틸렌에틸이써모노올레이트하이드로카본은 비중 0.83 ~ 0.87, 굴절율 1.44 ~ 1.48, 수분 0.1% 이하인 것을 사용하고, 폴리옥시에틸렌알킬이써썩시닉은 비중 1.02 ~ 1.04, 점도 200 ~ 250cps, 산가 112 ~ 102인 것을 사용한다. The polyoxyethylene ethyl ether monooleate hydrocarbon and polyoxyethylene alkyl ether isnic as a dispersant capable of preparing a very high solids type film waterproofing agent without using an additional solvent in 95% solid fluorine-modified tar urethane. Polyoxyethylene ethyl thermomonohydrohydrocarbon has a specific gravity of 0.83 to 0.87, a refractive index of 1.44 to 1.48, and a water content of 0.1% or less. The polyoxyethylene alkyl ether tricyclic has a specific gravity of 1.02 to 1.04, viscosity of 200 to 250 cps, and acid value. Use 112 to 102.
여기서 수치한정의 이유는 0.3wt% 미만을 사용시는 분산이 잘 이루어지지 않아 제품의 점도가 높고, 1.1wt% 보다 많이 사용하면 도막의 내수성이 저하하여 장시간 물에 침적시 물성이 감소하기 때문에 고형분 95%의 불소 변성 타르우레탄 55.7 ~ 65.7wt%에 0.3 ~ 1.1 wt%를 사용하는 것이 바람직하다. The reason for the numerical limitation is that the viscosity of the product is high because the dispersion is not performed well when using less than 0.3wt%, and when it is used more than 1.1wt%, the water resistance of the coating film decreases and the physical properties decrease when it is immersed in water for a long time. It is preferable to use 0.3 to 1.1 wt% in 55.7 to 65.7 wt% of fluorine-modified tar urethane.
이와 같이 제조한 불소 변성 타르우레탄 도막방수재를 건축 토목 구조물 등에 스프레이, 고무 헤라 및 흙손 등을 이용하여 도포하면 우수한 인장강도, 저온유연성, 내충격성, 내약품성 및 내마모성을 발휘하여 1회에 2.5 ~ 3mm 두께로 도포하더라도 경화시간이 빠르고, 특히 접착강도와 내균열 추종성이 우수하고, 내구성이 증대하여 누수로 인한 구조물의 노화 현상을 방지할 수 있다. The fluorine-modified tar urethane coating waterproofing material thus prepared is applied to a building civil structure using spray, rubber spatula, trowel, etc. to exhibit excellent tensile strength, low temperature flexibility, impact resistance, chemical resistance and abrasion resistance at a time of 2.5 to 3mm. Even if it is applied in thickness, the curing time is fast, in particular, the adhesive strength and the crack tracking resistance is excellent, and durability can be increased to prevent the aging phenomenon of the structure due to leakage.
또한 전면밀착공법으로 시공됨으로 인해 누수발생시 누수발생부위만을 보수할 수 있어서 매우 편리하다. 종래와 같은 부분절연공법을 이용하면 시트층 하부에 형성된 엠보싱 돌기 사이가 물 통로가 되어 어느 부분에서 누수가 발생하는지 확인하기가 어려웠지만 본 발명과 같이 방수층 구조가 하부는 부직포를 포함한 하부면은 평탄하게 하여 도포된 도막방수재와 전면접착공법으로 접착시키게 되면 누수 부위를 찾아 내어 보수하기가 매우 쉽게 된다.In addition, it is very convenient because it can be repaired only when the leakage occurs due to the construction by the close contact method. Using the partial insulation method as in the prior art, it was difficult to check where the leakage occurs due to the water passage between the embossing protrusions formed on the lower portion of the sheet layer, but the bottom surface of the waterproof layer structure including the nonwoven fabric is flat as in the present invention. When it is adhered to the coated film waterproofing material and the front adhesive method, it is very easy to find and repair the leaking part.
이하, 상기 제조방법에 따라 제조된 본 발명의 불소 변성 타르우레탄 도막방수재의 시험 결과치는 표 1과 같다.
Hereinafter, the test results of the fluorine-modified tar urethane coating waterproofing material of the present invention prepared according to the above production method are shown in Table 1.
(표 1)불소 변성 타르우레탄 도막방수재의 시험 결과Table 1 Test results of fluorine-modified tar urethane coating waterproofing materials
상기와 같은 성능을 가지는 본 발명에 따른 불소 변성 타르우레탄 도막방수재는 내구성, 내약품성, 접착성 내노화성, 내오존성, 내후성, 내열성 및 발수성이 우수하고, 경화시간이 빠르고 기포가 발생하지 않아 시공시 작업성이 우수한 특성을 갖는 것으로 불소 변성 타르우레탄 도막방수재는 기존 폴리우레탄 도막방수제에서 발생하는 표면 및 도막 밑부분의 경화는 쉽게 진행되지만 도막 내부는 경화된 도막 표면으로부터의 습기 침투가 어려워 경화 진행 속도가 느리며 경화 중 해리되는 알데히드에 의한 부풀음 하자가 자주 발생되는 문제점을 원천적으로 해결하게 된다.Fluorine-modified tar urethane coating waterproofing material according to the present invention having the performance as described above is excellent in durability, chemical resistance, adhesive aging resistance, ozone resistance, weather resistance, heat resistance and water repellency, construction time is fast and does not generate bubbles The fluorine-modified tar urethane coating waterproofing material has excellent workability and hardening of the surface and the bottom of the coating that occur in existing polyurethane coating waterproofing agent proceeds easily, but it is difficult to penetrate moisture from the hardened coating surface inside the coating film. Slowly and swelling defects caused by aldehydes that dissociate during curing often solve the problem that often occurs.
이하 본 발명의 불소 변성 타르우레탄 도막방수재를 이용한 시공방법을 설명한다. Hereinafter, the construction method using the fluorine-modified tar urethane coating waterproofing material of the present invention.
도 1은 본 발명에 따른 방수층 구조를 보인 예시도이고, 도 2는 본 발명의 방수시트층에 사용된 한 실시예에 따른 시트를 보인 예시도이다. 1 is an exemplary view showing a waterproof layer structure according to the present invention, Figure 2 is an exemplary view showing a sheet according to an embodiment used in the waterproof sheet layer of the present invention.
도시된 바와 같이 본 발명은 슬라브층(1) 상부에 프라이머층(2)을 도포하고, 그 상면에 상술한 바와 같은 제조방법에 따라 제조된 불소 변성 타르우레탄 도막방수재층(3)을 도포하고, 그 위에 전면 밀착되는 방수시트층(4)을 형성하고, 그 위에 보호몰탈층(5)을 형성하는 비노출 공법으로 시공된다. 물론 필요에 따라 상기 보호몰탈층 상부에 누름 콘크리트층(6)을 형성할 수 있다. 여기서 프라이머층은 불소 변성 타르우레탄 도막방수재와 동일 재질을 엷게 칠한 층이다.
As shown in the present invention, the
상기 본 발명에 사용되는 방수시트층은 폴리비닐클로라이드시트 하부에 부직포가 형성되고, 폴리비닐클로라이드시트의 상면 즉, 보호몰탈이 도포되는 면은 2가지 크기의 구형 돌기가 연속 배열되어 형성된 인플랫(Inflate) 방수시트층을 사용한다. In the waterproof sheet layer used in the present invention, a non-woven fabric is formed under the polyvinyl chloride sheet, and the upper surface of the polyvinyl chloride sheet, that is, the surface on which the protective mortar is applied, has an inflat formed by continuously arranging two sized spherical protrusions ( Inflate) Use a waterproof sheet layer.
이와 같이 사용하면 하부면을 이루는 부직포에는 불소 변성 타르우레탄 도막방수재가 스며들어 전면 밀착 고정되게 된다. When used in this way, the non-woven fabric forming the lower surface is soaked in fluorine-modified tar urethane coating waterproofing material is in close contact with the entire surface.
또한 상면에 형성된 2가지 크기의 구형 돌기는 골격재 역할을 하여 그 위에 도포되는 보호몰탈을 강하게 고정 지지되어 내구성이 높아지게 된다.In addition, the spherical protrusions of the two sizes formed on the upper surface serve as a skeleton and are strongly fixed and supported by a protective mortar applied thereon, thereby increasing durability.
2가지의 서로 다른 구형 돌기로 형성한 이유는 콘크리트 제조시 시멘트와 다양한 크기의 골재 즉, 큰 골재와 그 보다 작은 골재를 사용하는 것과 같은 이유이다. 동일한 크기의 골재로만 배열하게 되면 그 사이 사이 공간의 강도가 취약해질 수 있기 때문에 취약부분의 강도 보강을 하기 위함이다. The reason for the formation of two different spherical bumps is the same as the use of cement and aggregates of various sizes, ie large aggregates and smaller aggregates, in the manufacture of concrete. If only the aggregate of the same size is arranged to strengthen the strength of the weak part because the strength of the space between them may be weak.
이와 같이 구성된 폴리비닐클로라이드 방수시트층을 불소 변성 타르우레탄 도막방수재 시공 전에 형성시킬 경우 폴리우레탄에 포함된 용제가 폴리비닐클로라이드 방수시트층에 서서히 흡수됨으로써, 시트가 수축되는 문제와 엠보싱 시트의 엠보싱면이 바닥에 위치여 물의 통로 역활을 하게 되어 누수 현상이 발생시 시공 전면을 걷어내야 하는 문제점을 해결하게 된다. 물론 본 발명의 방수시트층은 통상의 폴리비닐클로라이드시트 어느 것을 사용해도 된다.
When the polyvinyl chloride waterproof sheet layer configured as above is formed before the fluorine-modified tar urethane coating waterproofing material is applied, the solvent contained in the polyurethane is gradually absorbed by the polyvinyl chloride waterproof sheet layer, thereby causing the sheet to shrink and the embossed surface of the embossed sheet. It is located on the floor to act as a water passage to solve the problem of having to remove the front of the construction when a leak occurs. Of course, you may use any of the normal polyvinyl chloride sheets for the waterproof sheet layer of this invention.
