본 발명은 알카리실리케이트, 계면활성제, 아크릴-에폭시 공중합체, 수소화 폴리터르펜, 무기계 충진제를 포함하는 것을 특징으로 하는 침투형 방수제 조성물에 관한 것이다. The present invention relates to a penetrating waterproofing agent composition comprising an alkali silicate, a surfactant, an acrylic-epoxy copolymer, a hydrogenated polyterpene, and an inorganic filler.
Description
본 발명은 콘크리트 구조물 등의 콘크리트의 표면에 도포됨으로써 내균열성, 방수성 등을 향상시키는 침투형 방수제 조성물에 관한 것이다. The present invention relates to a penetrating waterproofing agent composition that improves crack resistance and waterproofness by being applied to the surface of concrete such as a concrete structure.
일반적으로, 콘크리트 구조물은 건조수축과 균열수축 현상에 의한 균열이 발생되며, 이러한 균열로 방수성능이 필요한 구조물에 누수가 발생되게 된다. 또한 방수성능이 없는 콘크리트의 경우 콘크리트 내부에 물이 침투하여 동결융해가 발생되고 각종 자연환경과 인공적 작업에 의한 염해, 중성화, 화학적 침식 등 다양한 열화요인이 발생된다.In general, concrete structures are cracked due to drying shrinkage and crack shrinkage, and these cracks cause water leakage in structures requiring waterproof performance. In addition, in the case of concrete without waterproof performance, water penetrates the inside of the concrete, causing freezing and thawing, and various deterioration factors such as salt damage, neutralization, and chemical erosion caused by various natural environments and artificial operations occur.
종래, 상기한 문제점을 해결하기 위하여 에폭시, 우레탄 방수 등 다양한 특허기술들이 개시되어 있으며, 일 예로 대한민국 특허등록 제10-1804307호에서는 경질유 100 중량부, 실란계 커플링제 55 내지 65 중량부, 실리콘계 발수제 5 내지 10 중량부, 계면활성제 2 내지 4 중량부 및 물 25 내지 35 중량부로 이루어지며, 상기 경질유는 수소처리된 등유로 이루어지고, 상기 계면활성제는 폴리에틸렌 글리콜, 폴리프로필렌 글리콜, 폴리에틸렌 글리콜 노닐 페닐에테르, 폴리프로필렌 글리콜 노닐 페닐 에테르, 폴리에틸렌 글리콜 노닐 페닐 에테르와 폴리프로필렌 글리콜 노닐 페닐 에테르의 블록 코폴리머, 소듐 디옥틸 설포석시네이트, 폴리에틸렌 글리콜 알킬 에테르, 폴리에틸렌 글리콜 패티 에씨드에스터로 이루어진 그룹에서 선택된 하나 이상으로 이루어지는 것을 특징으로 하는 침투형 콘크리트 방수제를 제시하고 있다.Conventionally, in order to solve the above problems, various patent technologies such as epoxy and urethane waterproofing have been disclosed. For example, in Korean Patent Registration No. 10-1804307, 100 parts by weight of light oil, 55 to 65 parts by weight of a silane-based coupling agent, and a silicone-based water repellent 5 to 10 parts by weight, 2 to 4 parts by weight of surfactant, and 25 to 35 parts by weight of water, the light oil is made of hydrogenated kerosene, and the surfactant is polyethylene glycol, polypropylene glycol, polyethylene glycol nonyl phenyl ether , polypropylene glycol nonyl phenyl ether, block copolymers of polyethylene glycol nonyl phenyl ether and polypropylene glycol nonyl phenyl ether, sodium dioctyl sulfosuccinate, polyethylene glycol alkyl ethers, polyethylene glycol patty acid esters It proposes a penetration type concrete waterproofing agent characterized in that consisting of the above.
그러나 상기 기술은 모체인 콘크리트와 열팽창계수가 달라 시공 후 장시간 경과되면 접착면의 부착강도가 저하되어 방수층이 파괴되는 단점 있으며, 균열을 회복하지 않는 이상 균열이 확장되어 결국 최종적인 방수 성능을 발현하지 못하는 단점이 있다. However, the above technology has a disadvantage in that the adhesive strength of the adhesive surface is lowered and the waterproof layer is destroyed when a long time elapses after construction because the coefficient of thermal expansion is different from that of the parent concrete. There is a downside to not being able to.
이에 본 발명은 콘크리트의 방수성능 향상과 동시에 내균열성을 향상시킬 수 있는 방수제 조성물을 제공하고자 함이다. Accordingly, the present invention is to provide a waterproofing agent composition capable of improving the waterproofing performance of concrete and simultaneously improving the crack resistance.
상기와 같은 목적을 달성하기 위한 본 발명에 따른 침투형 방수제 조성물(이하 “본 발명의 조성물”이라함)은 알카리실리케이트, 계면활성제, 아크릴-에폭시 공중합체, 수소화 폴리터르펜, 무기계 충진제를 포함하는 것을 특징으로 한다. The penetrating waterproofing agent composition according to the present invention (hereinafter referred to as "the composition of the present invention") for achieving the above object includes an alkali silicate, a surfactant, an acrylic-epoxy copolymer, a hydrogenated polyterpene, and an inorganic filler. characterized by
하나의 예로 카복시메틸 셀룰로오스가 더 포함되는 것을 특징으로 한다. One example is characterized in that carboxymethyl cellulose is further included.
하나의 예로 라피노오스가 더 포함되는 것을 특징으로 한다. One example is characterized in that raffinose is further included.
하나의 예로 상기 무기계 충진제에는 알루미늄 분말과 지르코늄 분말 혼합물이 포함되는 것을 특징으로 한다. As an example, the inorganic filler includes a mixture of aluminum powder and zirconium powder.
앞서 설명한 바와 같이, 본 발명의 조성물은 콘크리트 구조물 등의 표면에 도포됨에 의해 내부조직을 치밀화 함으로써 내구성, 강도 등을 향상시키도록 하는 것은 물론 콘크리트 균열을 치유하여 방수성능 확보 및 균열의 추가 진행을 억제할 수 있는 장점이 있다. As described above, the composition of the present invention is applied to the surface of a concrete structure to densify the internal structure to improve durability and strength, as well as to heal cracks in concrete to secure waterproof performance and suppress further progress of cracks. There are advantages to doing so.
도 1은 본 발명이 적용된 예를 도시한 개략도이다. 1 is a schematic diagram showing an example to which the present invention is applied.
아래에서는 본 발명에 따른 양호한 실시 예 및 실험 예를 상세히 설명한다.Hereinafter, preferred embodiments and experimental examples according to the present invention will be described in detail.
본 발명의 조성물은 알카리실리케이트, 계면활성제, 아크릴-에폭시 공중합체, 수소화 폴리터르펜, 무기계 충진제를 포함하는 것을 특징으로 한다. The composition of the present invention is characterized by including an alkali silicate, a surfactant, an acrylic-epoxy copolymer, a hydrogenated polyterpene, and an inorganic filler.
본 발명의 조성물은 콘크리트 구조물 등의 표면에 2회 정도 도포를 하여 재령 28일 정도 경과되면 구조물의 표면에 방수층이 2 내지 4 cm 가량 만들수 있도록 하는 것으로, 도 1에서 보는 바와 같이 실리카겔 수화생성물은 콘크리트 내부에서 경화되어 표면경도 저항성, 압축강도 및 휨 강도를 증가시키며, 아울러 영구 보호막으로서 방수층을 형성토록 하는 것이다. The composition of the present invention is applied twice to the surface of a concrete structure so that a waterproof layer of about 2 to 4 cm can be formed on the surface of the structure after about 28 days of age. As shown in FIG. 1, the silica gel hydration product is concrete It is cured from the inside to increase surface hardness resistance, compressive strength and bending strength, and to form a waterproof layer as a permanent protective film.
방수성능 등을 위해 알카리실리케이트가 주제로 사용되는 바, 상기 알카리실리케이트는 그 종류를 한정하지 않으나 예로 Na2O·SiO2, Li2O·SiO2가 적용됨이 타당하다. Alkali silicate is used as a main material for waterproof performance, etc., and the type of alkali silicate is not limited, but it is reasonable to apply Na 2 O·SiO 2 and Li 2 O·SiO 2 as examples.
이러한 알카리실리케이트는 콘트리트의 Ca(OH)2와 반응하여 고분자의 실리콘 망상구조(-(Si-O-Si)n-)를 형성하여 방수효과를 발현시키는 것이다. This alkali silicate reacts with Ca(OH) 2 of concrete to form a polymeric silicon network structure (-(Si-O-Si)n-) to express a waterproof effect.
상기 계면활성제는 그 종류를 한정하지 않으며, 예로 실리콘계 계면활성제가 적용될 수 있는 바, 상기 실리콘계 계면활성제는 콘크리트 내부에 제품 침투력을 향상시키는 목적으로 사용되는 것으로, 디메치콘 코폴리올, 알킬 폴리글루코사이드, 실리콘 인산 에스테르 등이 적용될 수 있다. The surfactant is not limited in its type, and for example, a silicone-based surfactant may be applied. The silicone-based surfactant is used for the purpose of improving product penetration into concrete, dimethicone copolyol, alkyl polyglucoside, and silicone. Phosphoric acid esters and the like can be applied.
상기 아크릴-에폭시 공중합체는 페이스트 내부에 폴리머 필름을 형성하여 휨, 인장 및 부착강도를 증진시킬 뿐만 아니라 폴리머 필름막으로 인하여 내구성을 개선시킨다. The acrylic-epoxy copolymer forms a polymer film inside the paste to improve bending, tensile and adhesive strength, as well as improving durability due to the polymer film.
상기 수소화 폴리터르펜은 빠른 경화속도 및 압축강도 등의 물리적 특성을 개선시키는 기능이 발현되도록 한다. The hydrogenated polyterpene allows the function of improving physical properties such as fast curing speed and compressive strength to be expressed.
상기 무기계충진제는 강도를 향상시키는 것은 물론 구조물의 미세균열에 충진되어 내구성을 향상시키고, 균열을 보강하는 기능이 발현되도록 하는 것이다. The inorganic filler not only improves the strength, but also fills the microcracks of the structure to improve durability and to express the function of reinforcing the cracks.
바람직하게 본 발명의 조성물은 알카리실리케이트 100중량부에 대해 계면활성제 1 내지 3중량부, 아크릴-에폭시 공중합체 1 내지 3중량부, 수소화 폴리터르펜 0.1 내지 1중량부, 무기계 충진제 5 내지 10중량부를 포함하도록 배합하는 것이 타당하다. Preferably, the composition of the present invention contains 1 to 3 parts by weight of a surfactant, 1 to 3 parts by weight of an acrylic-epoxy copolymer, 0.1 to 1 part by weight of a hydrogenated polyterpene, and 5 to 10 parts by weight of an inorganic filler based on 100 parts by weight of an alkali silicate. It is reasonable to mix it so that it contains.
한편 증점제가 첨가되어 균열부분에 상기 무기충진제 등이 침투되도록 하면서 부착력을 강화시키도록 하는 것이 타당한데, 이러한 증점제의 첨가에 의해 부착강도 등은 향상되나 충진성이 저하되는 문제가 발생할 수 있다.On the other hand, it is reasonable to add a thickener to enhance adhesion while allowing the inorganic filler to penetrate into the cracked portion. However, the addition of such a thickener improves adhesion strength, but may cause a problem of deterioration in fillability.
이에 본 발명에서는 카복시메틸 셀룰로오스가 증점제로 포함되도록 하는 예를 제시하는데, 상기 카복시메틸 셀룰로오스는 점탄성을 향상시킴으로써 분산과정에서는 점성을 낮추어 균일한 분산이 이루어지도록 하여 균열부위 등에 무기충진제 등이 충분한 충진이 이루어지도록 함과 동시에 분산 후 점성이 복원되도록 하여 충진후 균열부위에서 무기충진제에 부착강도를 증진시키도록 하는 것이다. Accordingly, the present invention provides an example in which carboxymethyl cellulose is included as a thickener, and the carboxymethyl cellulose improves viscoelasticity, thereby lowering the viscosity during the dispersion process so that uniform dispersion is achieved so that sufficient filling of cracks and the like with inorganic fillers is possible. At the same time, the viscosity is restored after dispersion to improve the adhesion strength to the inorganic filler at the cracked portion after filling.
바람직하게 알카리실리케이트 100중량부에 대해 카복시메틸 셀룰로오스가0.01 내지 0.5중량부로 배합되도록 함이 타당하다. Preferably, it is appropriate to mix carboxymethyl cellulose in an amount of 0.01 to 0.5 parts by weight based on 100 parts by weight of the alkali silicate.
한편 본 발명의 조성물에는 수소화 폴리터르펜이 첨가되도록 하여 조기경화가 이루어지도록 함에 따라 수분증발에 따른 페이스트의 건조수축균열 등이 유발될 수 있다. 이에 본 발명의 조성물에는 라피노오스가 더 포함되는 예가 제시되는데, 라피노오스는 보습제로서 기능이 발현되도록 하여 상기에서 언급한 건조수축 등에 의해 유발되는 균열에 대한 저항성을 향상시키도록 하는 것이다. On the other hand, as hydrogenated polyterpene is added to the composition of the present invention to achieve early curing, drying shrinkage cracking of the paste due to moisture evaporation may be induced. Accordingly, an example in which raffinose is further included in the composition of the present invention is presented, and raffinose functions as a moisturizing agent to improve resistance to cracking caused by drying shrinkage and the like mentioned above.
바람직하게 알카리실리케이트 100중량부에 대해 라피노오스가 0.01 내지 0.5중량부로 배합되도록 함이 타당하다. Preferably, it is appropriate to blend 0.01 to 0.5 parts by weight of raffinose with respect to 100 parts by weight of the alkali silicate.
또한 본 발명에서는 상기 무기계 충진제에 알루미늄 분말과 지르코늄 분말 혼합물이 포함되는 예를 제시하고 있다. In addition, the present invention suggests an example in which a mixture of aluminum powder and zirconium powder is included in the inorganic filler.
상기 알루미늄 분말은 Ca와 Na가 존재할 때 다음과 같은 반응에 의해서 수소가스를 발생하며, 발포되고 팽창하는 특성을 가지고 있다.The aluminum powder generates hydrogen gas by the following reaction when Ca and Na are present, and has characteristics of foaming and expansion.
2Al + Ca(OH)2 + 2H2O → CaAl2O4 + 3H2 2Al + Ca(OH) 2 + 2H 2 O → CaAl 2 O 4 + 3H 2
2Al + 2NaOH + 2H2O → 2NaAlO3 + 3H2 2Al + 2NaOH + 2H 2 O → 2NaAlO 3 + 3H 2
따라서 무기계 충진제에 알루미늄 분말이 포함됨에 의해 페이스트의 팽창을 유도하여 수축균열에 대한 저항성을 향상시키도록 하는 것이다. Therefore, by including aluminum powder in the inorganic filler, the expansion of the paste is induced to improve resistance to shrinkage cracking.
그런데 알루미늄 분말만을 첨가하는 경우 상기 반응식에서 보는 바와 같이 수소가스가 발생되어 이러한 수소가스가 외부로 배출되면서 표면공극을 형성시키는 문제가 있다. 이러한 표면공극은 균열발생 포인트로서 작용될 수 있고, 이러한 표면공극을 통해 탄산화가 이루어질 수 있는 등의 문제가 있다. However, when only aluminum powder is added, hydrogen gas is generated as shown in the above reaction formula, and as such hydrogen gas is discharged to the outside, there is a problem of forming surface pores. Such surface voids can act as crack generation points, and there are problems such as carbonation through these surface voids.
또한 본 발명의 조성물에는 조기경화를 위해 수소화 폴리터르펜이 첨가되도록 하는데 상기 수소화 폴리터르펜의 경우도 반응과정에서 수소가스를 발생시켜 상기와 같은 문제가 야기될 수 있다. In addition, hydrogenated polyterpene is added to the composition of the present invention for early curing. In the case of the hydrogenated polyterpene, hydrogen gas is also generated during the reaction, which may cause the above problem.
이에 본 발명에서는 상기 무기계 충진제에 지르코늄의 더 첨가에 의해 수소가스를 제거하여 수소가스에 의해 형성될 수 있는 상기와 같은 문제점을 해결토록 하는 것이다. Accordingly, the present invention is to solve the above problems that may be formed by hydrogen gas by removing hydrogen gas by further adding zirconium to the inorganic filler.
바람직하게 알루미늄 분말 및 지르코늄은 중량비로 (8 : 2) 내지 (9 : 1)의 혼합비로 배합토록 하는 것이 타당하다. Preferably, it is reasonable to mix aluminum powder and zirconium in a mixing ratio of (8: 2) to (9: 1) in weight ratio.
이하 본 발명의 조성물의 실험예를 설명한다. Hereinafter, experimental examples of the composition of the present invention will be described.
이하 실시예 1은 알카리실리케이트 100중량부에 대해 계면활성제 3중량부, 아크릴-에폭시 공중합체 3중량부, 수소화 폴리터르펜 1중량부, 무기계 충진제로 알루미늄 분말 5중량부, 증점제로 검 0.1중량부를 배합된 시료이며, 실시예 2는 실시예 1과 동일하되 증점제로 검 대신 카복시메틸 셀룰로오스가 0.1중량부가 배합된 시료이고, 실시예 3은 실시예 2와 동일하되 라피노오스 0.1중량부가 더 배합된 시료이며, 실시예 4는 실시예 3과 동일하되 지르코늄 분말 0.5중량부가 더 배합된 시료이다.Example 1 below contains 3 parts by weight of surfactant, 3 parts by weight of acrylic-epoxy copolymer, 1 part by weight of hydrogenated polyterpene, 5 parts by weight of aluminum powder as an inorganic filler, and 0.1 part by weight of gum as a thickener based on 100 parts by weight of alkali silicate. Example 2 is the same as Example 1, but with 0.1 part by weight of carboxymethyl cellulose instead of gum as a thickener, Example 3 is the same as Example 2, but with 0.1 part by weight of raffinose. Sample, and Example 4 is the same as Example 3, but a sample in which 0.5 parts by weight of zirconium powder was further mixed.
<투수성 실험> <Permeability test>
내투수성능을 평가하기 위하여 KS F 4930에 의거 각 실시예들을 도포한 것을 14일간 표준상태에서 양생 후 투수시험장치를 사용하여 1 bar의 수압을 1시간 동안 가하여 내투수성을 평가하였다. In order to evaluate the water permeability resistance, each of the examples applied in accordance with KS F 4930 was cured under standard conditions for 14 days, and then a water pressure of 1 bar was applied for 1 hour using a water permeability test device to evaluate the water permeability.
<내염화성능 실험><Improvement resistance test>
내염화성능을 평가하기 위하여 KS F 4930의 의거 각 실시예들을 도포한 것을 14일간 표준상태에서 양생 후 5% 염화나트륨 수용액에 7일간 침지하여 침지 전ㆍ후의 질량변화를 통하여 내염화성능을 평가하였다.In order to evaluate the flame resistance performance, each of the examples applied in accordance with KS F 4930 was cured under standard conditions for 14 days, then immersed in 5% sodium chloride aqueous solution for 7 days, and the flame resistance performance was evaluated through mass change before and after immersion.
상기 표 1에서 보는 바와 같이 내투수성 및 내염화성면에서 실시예 1보다 실시예 2가 더 좋은 결과를 도출하는 것을 알 수 있는데 이는 실시예 2에서는 실시예 1과 달리 증점제로 카복시메틸 셀룰로오스가 첨가됨에 기인한 것으로 판단되는데, 이는 카복시메틸 셀룰로오스의 첨가에 의해 무기계 충진제가 분산과정에서는 균일한 분산이 이루어지도록 함으로써 균열부위 등에 무기충진제의 충분한 충진이 이루어진 후에 점성이 발현되도록 함에 기인한 것으로 판단된다. As shown in Table 1, it can be seen that Example 2 produces better results than Example 1 in terms of water permeability and flame resistance, which is different from Example 1 in Example 2 because carboxymethyl cellulose is added as a thickener This is determined to be due to the addition of carboxymethyl cellulose so that the inorganic filler is uniformly dispersed in the dispersion process, so that the viscosity is developed after sufficient filling of the inorganic filler such as the crack area.
또한 내투수성 및 내염화성면에서 실시예 2보다 실시예 3이 더 좋은 결과를 도출하는 것을 알 수 있는데, 이는 실시예 3에 라피노오스가 더 첨가되어 균열저항성이 향상됨에 기인한 것으로 판단된다. In addition, it can be seen that Example 3 yields better results than Example 2 in terms of water permeability and flame resistance, which is believed to be due to the improvement of crack resistance due to the addition of raffinose to Example 3.
또한 실시예 4가 내투수성 및 내염화성면에서 가장 좋은 결과를 도출하고 있는 것을 알 수 있는데, 이는 무기계 충진제에 지르코늄이 더 첨가됨에 기인한 것으로, 실시예 3 등은 무기계 충진제로 알루미늄 분말만이 첨가되고, 또한 조기경화를 위해 수소화 폴리터르펜이 첨가됨에 따라 반응과정에서 수소가스가 발생되어 표면공극이 문제가 유발되는데, 실시예 4의 경우 발생되는 수소가스가 지르코늄에 의해 제거가 되어 표면공극의 문제가 해결됨에 기인한 것으로 판단된다. In addition, it can be seen that Example 4 produces the best results in terms of water permeability and flame resistance, which is due to the addition of zirconium to the inorganic filler. In Example 3, only aluminum powder is added as an inorganic filler. In addition, as hydrogenated polyterpene is added for early curing, hydrogen gas is generated in the reaction process, causing problems with surface pores. In the case of Example 4, the generated hydrogen gas is removed by zirconium and It is believed that the problem has been resolved.
