Description
본 발명은 수지조성물과 이를 이용한 차열성 콘크리트구조물 방수공법에 관한 것으로, 특히 콘크리트구조물에 수지조성물을 코팅하고, 상기 수지조성물 상에 보강섬유를 설치하며, 상기 보강섬유 상에 수지조성물을 코팅한 수지조성물과 이를 이용한 차열성 콘크리트구조물 방수공법에 관한 것이다.The present invention relates to a resin composition and a waterproofing method for a heat-insulating concrete structure using the resin composition. More particularly, the present invention relates to a resin composition comprising a resin composition coated on a concrete structure, a reinforcing fiber provided on the resin composition, And a waterproofing method for a heat-resistant concrete structure using the same.
일반적으로 건축물의 옥상, 바닥, 지하 주차장 등과 같이 수분과 접할 수 있는 부위에는 수분이 내부로 스며드는 것을 방지하기 위하여 구조물의 표면에 방수층을 형성하는 방수공사가 시행하고 있다.In general, waterproofing works are performed to form a waterproof layer on the surface of the structure in order to prevent moisture from penetrating into the interior of the building, such as a roof, a floor, and an underground parking lot.
이러한 방수의 형태는 건축물에 있어서 지붕, 실내, 수조류 및 지하방수로 구분될 수 있고, 특히 옥상방수의 경우에는 아스팔트 방수, 시트 방수, 우레탄 방수 및 고무 아스팔트 방수 등이 시공되어 왔다.This type of waterproofing can be divided into roof, interior, water birds and underground waterproofing in buildings, and in case of roof waterproofing, asphalt waterproofing, sheet waterproofing, urethane waterproofing and rubber asphalt waterproofing have been applied.
이러한 종래의 방수 시공은 콘크리트를 숙성시키는 과정에서 방수액을 첨가하여 옥상을 짓거나, 또는 방수액을 이용하여 적층 후에 시트 등을 이용하여 마감하는 등의 방법을 이용하였다.In the conventional waterproofing method, a waterproofing liquid is added to the concrete in the process of aging the concrete, and then a roof is formed, or a waterproofing liquid is used for laminating and then finishing using a sheet or the like.
그러나 이러한 방수 시공에 의하더라도 건축물의 준공 후 유지관리의 부족으로 콘크리트의 부식, 누수 등의 문제가 발생하여 그 대책 마련에 고심하고 있는 실정이다.However, even after such a waterproofing construction, corrosion of concrete due to lack of maintenance after completion of construction and problems such as leakage occur, and the problem is being researched.
누수는 구조물의 성능 저하를 가장 먼저 알려주는 신호임과 동시에, 주거 생활 및 시설물의 사용상 불편함을 주는 주원인이기도 하다.Leakage is the first signal to notify the performance degradation of the structure, and it is also the main cause of inconvenience in the use of residential life and facilities.
누수 하자에 따른 보수 비용은 초기 시공비의 2∼3배가 투입되지만, 완전한 누수 보수가 어렵고, 시간이 지나면서 재누수가 발생되어 또다시 보수해야 하는 시행착오가 반복됨으로써 그에 따른 막대한 비용손실이 발생하고 있다.The repair cost due to the leakage is 2 ~ 3 times the initial construction cost but it is difficult to repair the leak completely, and the leakage and leakage are repeated over time. have.
종래의 방수공법은 크게 노출 방수공법과 비노출 방수공법으로 나누어지는데, 이 중 노출 방수공법으로서 가장 많이 사용되는 것은 탄성과 신율이 우수한 폴리우레탄 방수재를 사용한 도막 방수공법과 시트를 이용한 시트방수공법이다.The conventional waterproofing method is divided into an exposure waterproofing method and an unexposed waterproofing method. Among them, the most commonly used waterproofing method is a waterproofing method using a polyurethane waterproofing material having excellent elasticity and elongation and a sheet waterproofing method using a sheet.
구체적으로, 노출 방수공법으로 사용되는 공법은 아래와 같다.Specifically, the method used in the exposure waterproofing method is as follows.
첫째, 탄성 우레탄 도막 방수공법First, elastic urethane coating waterproofing method
둘째, 연질 에폭시 도막 방수공법Second, soft epoxy coating waterproofing method
셋째, 무기질 탄성 도막 방수공법Third, inorganic elastic film waterproofing method
넷째, 고무화 아스팔트 도막 방수공법Fourth, rubberized asphalt coating waterproofing method
다섯째, 고무화 도막 방수공법Fifth, rubber film coating waterproofing method
여섯째, 복합시트방수공법이 있다.Sixth, there is a composite sheet waterproofing method.
여기서, 상기한 탄성 우레탄 3mm 두께 도막 방수공법은 가장 많이 시공하고 있는 공법으로 탄성이 있고 신율이 우수하여 콘크리트에 크랙이 발생하여도 방수층에 크랙 발생이 없어 방수성이 우수하다.Here, the above-mentioned elastic urethane 3 mm thick coating waterproofing method is the most widely used construction method and has elasticity and excellent elongation, so that even when cracks are generated in concrete, there is no crack in the waterproof layer and waterproof property is excellent.
그렇지만, 상기 우레탄 도막 방수공법은 두께가 3mm 이상의 도막을 형성하여야 방수 특성이 양호하나, 3mm 이하 방수층에 물이 고이면 우레탄의 투수성 및 통기성에 의하여 내부로 물이 스며들므로, 반드시 물매 작업을 잘하여야 물이 스며드는 문제점을 해결할 수 있다.However, since the urethane coating waterproofing method has good waterproof property when a coating film having a thickness of 3 mm or more is formed, the water penetrates into the water due to the permeability and permeability of the urethane when the waterproof layer is less than 3 mm, The problem of water penetration can be solved.
또한, 상기 연질 에폭시 방수공법은 방수성이 양호하여 1회 도장으로도 방수성이 매우 우수하나 자외선에 노화가 심하여 옥외방수는 불가하고 지하층이나 식수 및 용수탱크 방수에 많이 시공하고 있다.In addition, the soft epoxy waterproofing method is excellent in waterproof property even though it has good waterproofing property even in a single coating. However, since it is aged with ultraviolet rays, it can not be used for outdoor waterproofing and is widely used for waterproofing of basement, drinking water and water tank.
그리고, 상기 무기질 탄성 도막 방수공법은 연질 아크릴수지를 포틀랜드 시멘트와 혼용하여 3mm정도 도막을 형성하여 방수처리를 하는 것이다.In the inorganic elastic coating film waterproofing method, a soft acrylic resin is mixed with Portland cement to form a coating film of about 3 mm and waterproofed.
그러나 상기 방수공법에 의하면, 물이 고이는 곳에서는 중합이 풀려 아크릴산으로 환원하므로 콘크리트와 중성화 반응이 발생하여 콘크리트 표면이 산화되고, 이로 인해 상기 도막층이 산화층과 접착되어 박리되는 문제점이 발생하였다.However, according to the waterproofing method, since the polymerization is released and reduced to acrylic acid at the place where the water is floated, the concrete surface is oxidized due to the neutralization reaction with the concrete, thereby causing the problem that the coating layer is peeled off from the oxide layer.
따라서, 옥상방수용으로는 부적합한 공법이다.Therefore, this method is unsuitable for roof waterproofing.
또한, 상기 고무화 아스팔트 도막 방수공법은 아스팔트에 고무를 녹여 수용화 시킨 다음 시멘트를 혼용하여 도막 방수하는 공법이다.Also, the rubberized asphalt coating waterproofing method is a method of waterproofing the asphalt by dissolving the rubber in the water and then cementing it together.
그러나 상기 고무화 아스팔트 도막은 자외선 노출에 의한 노화 및 균열 발생과, 에어 포켓 발생이 용이하여 내부 비노출 방수에는 사용하여도 외부 노출방수용으로는 사용이 불가한 공법이다.However, the rubberized asphalt coating film can not be used for external exposure and waterproofing even if it is used for internal unexposed waterproofing due to aging and cracking due to exposure to ultraviolet rays and easy generation of air pockets.
또한, 상기 고무화 도막 방수공법은 고무를 용제에 녹여 합성수지와 합성한 재질로 이 공법 역시 자외선에 약하므로 옥상방수보다는 교량이나 비노출 방수에 적합한 공법이었다.In addition, the rubberized film waterproofing method is a synthetic material obtained by dissolving rubber in a solvent and synthesized with a synthetic resin, and this method is also applicable to bridging and non-visible waterproofing rather than rooftop waterproofing because it is also resistant to ultraviolet rays.
그리고, 상기 복합시트공법은 고무화 아스팔트 시트나 합성고무 시트를 콘크리트 전 바탕면에 깔고, 이음부위에 우레탄 수지를 바르고 유리섬유를 대고 접합시킨 공법으로, 시트는 상온시공이 가능하며, 기후 및 오존 등에 대한 내구성이 우수하고, 전체적으로 일정한 두께의 방수층을 확보할 수 있어 많이 사용되고 있다.The composite sheet method is a method in which a rubberized asphalt sheet or a synthetic rubber sheet is laid on the entire surface of concrete, urethane resin is applied to the joint portion, and glass fiber is bonded to the joint portion. And is widely used because a waterproof layer having a uniform thickness can be secured as a whole.
그러나 복잡한 부위의 방수시공이 어렵고, 시트 간 이음 부위에서의 완전 접합성을 꾀할 수 없어 크랙발생으로 누수 사고가 발생하고, 누수가 발생할 경우 부분보수가 어렵고 방수층 전체를 걷어내고 재시공함으로 많은 비용이 발생하고 방수층이 바닥에 붙지않고 들떠 있어 결로현상이 심하여 모체가 부식되는 문제가 있다.However, it is difficult to apply waterproofing to complicated areas, and it is impossible to achieve complete bonding at the joints between the sheets. As a result, water leakage occurs due to cracks, and partial repair is difficult when water leakage occurs. There is a problem that the waterproof layer does not stick to the floor and is excited and the condensation phenomenon is severe and the mother body is corroded.
특히, 콘크리트에서의 수분증발로 인해 발생하는 에어 포켓 현상은 콘크리트 모체의 수분 외에 표면 콘크리트의 핀 홀 또는 모르타르의 박리 등에 의해 밀봉된 공기층의 팽창에 의해서도 발생하는 문제가 있다.Particularly, the air pocket phenomenon caused by moisture evaporation in concrete is also caused by the expansion of the air layer sealed by the pinhole or mortar peeling of the surface concrete in addition to the moisture of the concrete matrix.
또한, 신축 콘크리트는 함수율이 높고, 콘크리트 자체는 알칼리성을 띠기 때문에, 종래에 사용되는 에폭시 프라이머 또는 우레탄 프라이머를 사용할 경우, 접착이 불량하여 박리 현상이 발생하는 문제점이 있다.In addition, since the stretch concrete has a high water content and the concrete itself has an alkaline property, there is a problem that peeling may occur due to poor adhesion when an epoxy primer or a urethane primer used conventionally is used.
즉, 종래에는 콘크리트 건축물 옥상 노출방수 시공상에서 젖은 콘크리트나 동절기 시공에서 함수율이 높아 습기로 인한 접착불량으로 들뜸이나 크랙 또는 에어 포켓이 발생하는 문제가 있고, 방수 도막이 투수되어 콘크리트구조물의 산화나 노화를 조장하거나 방수재가 콘크리트와 중성화 반응이 있는 문제가 있다.In other words, conventionally, there is a problem that the water content is high in the wet concrete or the winter construction on the roof-exposed waterproofing construction of the concrete building, and there is a problem that the adhesion failure due to the moisture causes the flooding, cracks or air pockets and the waterproofing film is permeated to oxidize or aging the concrete structure There is a problem that the waterproofing material promotes concrete and neutralization reaction.

이하, 본 발명을 첨부한 예시도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1은 본 발명에 따른 수지조성물을 이용한 콘크리트구조물 방수 과정을 도시한 공정도이다.1 is a process diagram showing a waterproofing process of a concrete structure using the resin composition according to the present invention.
이 도면에 도시된 바와 같이, 본 발명에 따른 수지조성물을 이용한 콘크리트구조물 방수공법은 콘크리트구조물의 표면을 정리하는 단계(S Ⅰ); 상기 콘크리트구조물의 표면에 수지조성물을 코팅하는 단계(S Ⅱ); 상기 수지조성물 상에 보강섬유를 설치하는 단계(S Ⅲ); 상기 보강섬유 상에 수지조성물을 코팅하는 단계(S Ⅳ)로 이루어진다.As shown in this figure, the concrete structure waterproofing method using the resin composition according to the present invention comprises the steps of arranging the surface of a concrete structure (S I); Coating a resin composition on the surface of the concrete structure (SII); Providing a reinforcing fiber on the resin composition (SIII); And coating a resin composition on the reinforcing fiber (SIV).
즉, 본 발명에 따른 수지조성물을 이용한 콘크리트구조물 방수공법은 콘크리트구조물 정리단계(S Ⅰ), 수지조성물 코팅단계(S Ⅱ), 보강섬유 설치단계(S Ⅲ), 수지조성물 코팅단계(S Ⅳ)를 순차적으로 시행하여 콘크리트구조물을 방수처리함을 특징으로 한다.That is, the waterproofing method of concrete structures using the resin composition according to the present invention is characterized in that the waterproofing method of the concrete structure includes the step of arranging the concrete structure (S Ⅰ), the step of coating the resin composition (S Ⅱ), the step of installing the reinforcing fiber (S Ⅲ) The concrete structure is waterproofed.
여기서, 상기 콘크리트구조물 정리단계(S Ⅰ)는 콘크리트구조물의 표면을 바탕을 치핑처리하고 청소한다.Here, the step of arranging the concrete structure (S I) chipping and cleaning the surface of the concrete structure.
즉, 콘크리트구조물의 열화 콘크리트의 치핑은 유압식 해머가 아닌 공압식 해머에 의하여 기존 콘크리트구조물에 미치는 충격을 최소화하여야 하고, 균일한 조도의 형성으로 접합력의 향상, 시공성, 경제성을 동시에 만족하여야 하는 상태에서 콘크리트 깨기(Breaking: 파괴), 그라인더의 면고르기 등을 치핑과 혼용하여 신구 콘크리트 접합을 시행토록 한다.That is, the chipping of the concrete structure deteriorates the impact of the existing concrete structure by the pneumatic hammer, not the hydraulic hammer, and it is required to minimize the impact on the existing concrete structure and to improve the bonding force, Breaking (breaking) and grinding of the surface of the grinder are combined with chipping to allow new and old concrete joints.
이어서, 상기 수지조성물 코팅단계는 콘크리트구조물의 바탕처리된 콘크리트구조물 표면에 수지조성물을 코팅한다.Next, the resin composition coating step coating the resin composition on the surface of the ground concrete structure of the concrete structure.
여기서, 상기 수지조성물은 우레탄 아크릴레이트(urethane acrylate) 10중량%; 부틸 아크릴레이트(butyl acrylate) 10중량%; 리튬실리케이트(Li2O3Si) 3중량%; 폴리메틸 메타크릴레이트(polymethyl methacrylate) 60중량%; 2-하이드록시 에틸 메타크릴레이트(hydroxyl ethyl methacrylate) 15중량%; 규산소다(Na2SiO3ㆍnH2O) 2중량%로 구성된다.Here, the resin composition contains 10% by weight of urethane acrylate; 10% by weight of butyl acrylate; 3% by weight of lithium silicate (Li 2 O 3 Si); 60% by weight of polymethyl methacrylate; 15% by weight of 2-hydroxyethyl methacrylate; And 2% by weight of sodium silicate (Na 2 SiO 3 .nH 2 O).
즉, 상기 수지조성물은 우레탄 아크릴레이트, 부틸 아크릴레이트, 리튬실리케이트, 폴리메틸 메타크릴레이트, 2-하이드록시 에틸 메타크릴레이트, 규산소다로 구성된다.That is, the resin composition is composed of urethane acrylate, butyl acrylate, lithium silicate, polymethyl methacrylate, 2-hydroxyethyl methacrylate, and sodium silicate.
여기서, 상기 우레탄 아크릴레이트(urethane acrylate)는 우레탄의 특성과 아크릴레이트의 특성을 모두 갖는 하이브리드(hybride) 수지이다.Here, the urethane acrylate is a hybride resin having both urethane and acrylate characteristics.
이러한 우레탄 아크릴레이트(urethane acrylate)는 일반적으로 우레탄 프리폴리머(urethane prepolymer)와 하이드록시 알킬 아크릴레이트와의 중합반응에 의해서 제조된다. These urethane acrylates are generally prepared by polymerization of a urethane prepolymer with a hydroxyalkyl acrylate.
우레탄 프리폴리머는 폴리올(polyol)과 이소시아네이트(isocyanate)의 중합 반응에 의해서 형성되며, 그 종류는 다양하다. Urethane prepolymers are formed by the polymerization reaction of polyol and isocyanate, and they are various.
또, 상기 하이드록시 알킬 아크릴레이트의 예로는 메틸 메타크릴레이트(methyl methacrylate), 2-하이드록시 에틸메타크릴레이트(2-hydroxyethylmethacrylate), n-부틸 아크릴레이트(n-butyl acrylate) 등이 있다.Examples of the hydroxyalkyl acrylate include methyl methacrylate, 2-hydroxyethylmethacrylate, n-butyl acrylate, and the like.
여기서, 상기한 우레탄 아크릴레이트(urethane acrylate)의 제조는 아디프산(adipic acid) 약 20 중량부와 이소시아네이트(isocyanate) 약 25 중량부를 반응기에서 열중합하여 우레탄 프리폴리머(urethane prepolymer)를 제조하였다. The urethane acrylate was prepared by thermally polymerizing about 20 parts by weight of adipic acid and about 25 parts by weight of isocyanate in a reactor to prepare a urethane prepolymer.
여기에, 메틸 메타크릴레이트 약 30 중량부, 2-하이드록시 에틸 메타크릴레이트(2-hydroxyl ethyl methacrylate) 약 25 중량부 및 알코올 약 0.3 중량부를 첨가한 후 열중합하여 우레탄 아크릴레이트(urethane acrylate)를 제조한다.About 30 parts by weight of methyl methacrylate, about 25 parts by weight of 2-hydroxyl ethyl methacrylate and about 0.3 part by weight of an alcohol were added and heat-polymerized to prepare urethane acrylate .
또한, 상기 리튬실리케이트(Li2O3Si)는 시멘트, 모르타르, 콘크리트, 칼슘실리케이트와 같은 시멘트 물질로 된 구조물의 표면강화제로서 사용된다. In addition, the lithium silicate (Li 2 O 3 Si) is used as a surface strengthening agent for a structure made of a cement material such as cement, mortar, concrete, calcium silicate.
리튬실리케이트(Li2O3Si)는 콘크리트 표면 내부로 침투하여 콘크리트의 유리 알칼리성분들과 화학적 반응을 일으켜 콘크리트를 강화시킨다. Lithium silicate (Li 2 O 3 Si) penetrates into the concrete surface and chemically reacts with the free alkaline components of the concrete to strengthen the concrete.
그리고, 상기 폴리메틸 메타크릴레이트(polymethyl methacrylate)는 우레탄 아크릴레이트(urethane acrylate)와 혼합 사용함으로써, 수지로 이루어진 구조물의 강도를 향상시킬 수 있다.The polymethyl methacrylate may be mixed with urethane acrylate to improve the strength of the structure made of resin.
또한, 상기 2-하이드록시 에틸 메타크릴레이트(2-hydroxyl ethyl methacrylate)는 본 발명에서 우레탄 아크릴레이트와 폴리메틸 메타크릴레이트 수지 이외에, 콘크리트구조물의 강도 보강을 위해 수지로서 하이드록시 에틸 메타크릴레이트(hydroxyl ethyl methacrylateA)을 추가로 사용할 수 있다.In addition, the 2-hydroxyl ethyl methacrylate may be used in the present invention in addition to urethane acrylate and polymethyl methacrylate resins. In addition to the urethane acrylate and polymethyl methacrylate resins, hydroxyethyl methacrylate hydroxyl ethyl methacrylateA) can be additionally used.
한편, 상기 규산소다(Na2SiO3ㆍnH2O)는 규산의 나트륨염이라 한다.On the other hand, the sodium silicate (Na 2 SiO 3 .nH 2 O) is referred to as a sodium salt of silicic acid.
조성(組成)에 따라 메타규산나트륨(NaSiO), 그 수화물인 오르토규산나트륨(NaSiO), 이규산나트륨(NaSiO) 등 여러 가지가 있으나 보통은 메타규산나트륨을 말한다.Depending on the composition, sodium metasilicate (NaSiO), its hydrate sodium orthosilicate (NaSiO), and sodium diacid (NaSiO), but usually refers to sodium metasilicate.
수화물(水和物)도 있으나 무수물은 석영과 탄산나트륨의 혼합물을 1,000℃로 가열 융해하여 고화(固化)시켜서 만든다.A hydrate is made by solidifying a mixture of quartz and sodium carbonate by heating and melting at 1,000 ° C.
메타규산나트륨은 물에 잘 녹으며 수용액은 가수분해하여 알칼리성이 된다.Sodium metasilicate dissolves well in water and the aqueous solution becomes alkaline by hydrolysis.
따라서 희박한 수용액에서는 산을 사용하여 정량할 수 있다.Therefore, in a dilute aqueous solution, it can be quantified using an acid.
이어서, 상기 수지조성물을 콘크리트구조물에 코팅한 후, 그 위에 보강섬유를 설치하는 단계(S Ⅲ)를 추가한다.Next, after the resin composition is coated on the concrete structure, a step (SIII) of installing reinforcing fibers thereon is added.
여기서, 상기 보강섬유는 아라미드 섬유 또는 아라미드 섬유에 수지조성물을 코팅한 것을 사용한다.Here, the reinforcing fiber is one obtained by coating an aramid fiber or an aramid fiber with a resin composition.
즉, 상기 아라미드섬유는 아마이드결합 -CONH가 벤젠고리와 같은 방향족고리를 결합시켜 고분자 폴리아마이드를 형성하고 있다.
인장강도, 강인성, 내열성이 뛰어나며 고강력·고탄성률을 갖고 있다.
5mm 정도 굵기의 가느다란 실이지만, 2t의 자동차를 들어올릴 정도의 막강한 힘을 가지고 있다.
불에 타거나 녹지 않으며, 500℃가 넘어야 비로소 검게 탄화(炭化)한다.
또 아무리 힘을 가해도 늘어나지 않아 가장 좋은 플라스틱 보강재(補强材)로 꼽힌다. That is, the aramid fiber has a structure in which an amide bond-CONH bonds an aromatic ring such as a benzene ring to form a polymer polyamide.
It has excellent tensile strength, toughness and heat resistance, and has high strength and high elasticity.
It is a thin thread with a thickness of about 5mm, but it has enough strength to lift a 2t car.
It does not burn or dissolve, and it must be carbonized (carbonized) only when it exceeds 500 ℃.
No matter how much force is applied, it is considered to be the best plastic reinforcement material.
이어서, 상기 보강섬유 상에 수지조성물을 코팅하는 단계(S Ⅳ)를 추가한다.Next, a step (S IV) of coating a resin composition on the reinforcing fiber is added.
여기서, 상기 보강섬유 상에 수지조성물을 코팅하는 것은 이미 수지조성물 코팅단계에서 설명하였으므로 더이상의 설명을 생략하기로 함을 밝혀둔다.
Here, coating of the resin composition on the reinforcing fiber has already been described in the resin composition coating step, and therefore, the description thereof will be omitted.
