이하에서는 본 발명에 의한 실시예를 들어 본 발명을 보다 상세히 설명하기로 한다. Hereinafter, it will be explained in more detail with the reference to examples according to the present invention.

본 발명에 의한 아크릴계 방수액 조성물은 아크릴 모노머 100중량부에 대하여 산화제수용액 100중량부, 촉매제로서 알콕시아민 2~10중량부, 마이크로시멘트 50~100중량부로 이루어진다. Bangsuaek acrylic composition according to the invention comprises per 100 parts by weight of acrylic monomer aqueous solution 100 parts by weight of an oxidizing agent, alkoxy amine of 2 to 10 parts by weight of micro-cement as a catalyst portion 50 to 100 wt. 상기 산화제 수용액은 산화제와 물이 1:1의 중량부로 혼합되는 것이 바람직하다. Said oxidizing agent is an oxidizing agent aqueous solution is water and one part by weight of the mixture is preferably 1. 또한, 본 발명에서 사용하는 산화제로서는 개미산인 것이 바람직하지만, 다른 균등한 산화제를 사용할 수도 있으며, 또한 바람직한 촉매제로서 알콕시아민을 사용하였으나, 이 역시 다른 균등한 촉매제를 사용할 수도 있다. In addition, there may be used an oxidizing agent Examples of the formic acid is a preferred, other equivalent oxidizing agent used in the present invention, but also an alkoxy amine used as the preferred catalyst, this may also use other equivalent catalyst.

본 발명에 의한 아크릴계 방수액 조성물은 콘크리트 구조물의 크랙에 대한 방수작업을 할 때 2액형으로 준비된다. Bangsuaek acrylic composition according to the invention are prepared in the two-component when the waterproof working for cracks in concrete structures. 즉, 제 1 용기에는 아크릴 모노머와 촉매제로서 알콕시아민 혼합물을 수용하고, 제 2 용기에는 마이크로 시멘트와 산화제수용액 혼합물을 수용하며, 작업시에 인젝션 펌프장치로 제 1 및 제 2 용기들에 수용된 방수액 성분 혼합물을 크랙에 주입하여 제 1 및 제 2 용기들의 혼합물들이 혼합될 때, 아크릴모노머가 가교반응을 하여 겔화 상태로 된다. That is, the first container accommodating the alkoxy amine the mixture as an acrylic monomer and a catalyst, and the second container bangsuaek component contained in the micro-cement and accommodates the oxidizing agent aqueous solution mixture, the first and second container to the injection pump device at the time of operation when the mixture to be injected into the cracks were first mixed and the mixture of the second vessel, the acrylic monomer by a crosslinking reaction is a gelled state.

상기 촉매제의 함량은 시공처의 작업환경, 즉 작업시의 온도와 누수량의 정도에 따라 조절되며, 특히 누수량이 많은 곳일수록 증가된다. The amount of the catalyst is treatment of the construction work environment, that is adjusted according to the degree of the temperature and the leakage at the time of operation, in particular is increased the more the leakage many places.

상기 촉매제의 함량이 2중량부 보다 적을 경우 아크릴모노머의 겔화가 지나치게 지연되는 문제점이 발생되고, 촉매제의 함량이 10중량부 보다 많은 경우 아크릴모노머의 겔화가 급격히 진행되어 크랙내로 방수액이 충분한 깊이로 침투되기 전에 아크릴모노머의 겔화로 요구되는 크랙내부 깊이에서 방수막이 형성되지 못하는 문제점이 발생된다. When the amount of the catalyst is less than 2 parts by weight is a problem that gelation is too delay of acrylic monomers occurs, if the amount of the catalyst is greater than 10 parts by weight, the gelation of the acrylic monomer proceeds rapidly penetrate into sufficient bangsuaek into the crack depth the gelled film is not waterproof is formed on the internal crack depth required to the problem of the acrylic monomer is generated before.

본 발명에서 사용되는 마이크로시멘트는 비표면적이 8,000cm 2 /g 정도인 것이 바람직하며, 비표면적이 3,260cm 2 /g 정도의 일반 시멘트를 사용할 수도 있으나, 일반 시멘트는 입경이 커서 크랙 내부로 침투되어야 하는 크랙 방수에는 적합하지 않고 일반 콘크리트 상면의 방수도막 형성에 사용될 수 있다. Micro-cement used in the present invention preferably has a specific surface area of about 8,000cm 2 / g, a specific surface area, but also use the common cement of about 2 / g 3,260cm, common cement should penetrate into the particle size of the large cracks not suitable for crack resistant may be used in the water film forming the upper surface of the plain concrete.

본 발명에 의한 아크릴계 방수액 조성물은 2액형으로 두개의 용기에 분리된 상태로 준비되어 크랙에 인젝션에 의해 혼합될 때, 크랙과 같은 밀폐된 공간에서 비중의 차이로, 즉 마이크로시멘트의 비중이 3.01 정도임에 비하여 아크릴모노머의 비중은 1.026 정도이고, 산화제수용액은 1.04 정도이므로 아크릴겔과 마이크로시멘트 혼합된 상태가 3개의 층으로 구분하여 이루어 진다. Acrylic bangsuaek composition according to the invention are prepared in a separate state to the two containers by two-component when mixed by spraying the cracks, to a difference in specific gravity in an enclosed space, such as a crack, that is, approximately the portion of micro-cement 3.01 being compared to the weight of the acrylic monomer is about 1.026, the oxidizing agent aqueous solution is about 1.04, so is achieved by the mix acrylic gel and micro-cement, separated by three layers.

즉, 비중이 3.01인 마이크로시멘트와 비중이 1.026인 아크릴모노머 및 비중이 1.04인 산화제수용액의 비중의 차이로 2액형의 아크릴계 방수액 조성물 성분들이 밀폐된 크랙에서 혼합될 때, 방수막은 상대적으로 비중이 큰 마이크로시멘트로서 콘크리트 위에 형성되는 제1층과, 상기 제1층 위에서 아크릴겔에 마이크로시멘트가 1:1로 분산된 상태의 제2층 및 최상층인 비중이 상대적으로 작은 아크릴겔로만 형성되는 제3층으로 된 방수막이 형성된다. That is, a specific gravity of 3.01, a micro-cement with a specific gravity of 1.026 an acrylic monomer and a specific gravity of 1.04 which when mixed in the acrylic bangsuaek composition component of the two-component are hermetically sealed cracks by the difference in specific gravity of the oxidizing agent aqueous solution, water resistant film is relatively specific gravity is large a third layer which is a second layer in a dispersed state in the first and the top layer of specific gravity to form only a relatively small acrylic gel: the first layer formed on the concrete as a micro-cement, wherein the micro-cement in the acrylic gel on the first floor 1 a film of water as formed.

그러나, 상기한 제 1, 2 및 3 층들은 출원인이 임의적으로 규정한 것으로 층들간의 경계가 명확하게 구분되지 않고 상대적으로 비중이 큰 마이크로시멘트가 주로 아래쪽에 분포하여 제1층을 이루지만, 아크릴겔에서 일부분의 마이크로시멘트가 분산된 상태로 제2층을 이루고, 최상층인 제3층은 비중이 상대적으로 작은 아크릴겔로만 형성되는 것으로 판단한 것에 의한 구분임을 밝혀둔다. However, only the above-described first, second, and third layers are the applicant, optionally one that boundary is clearly does not delimited relative to a specific gravity of larger micro-cement between the layers defined by a mainly distributed in the bottom fulfill the first layer, acrylic form the second layer in a micro-cement is dispersed in a portion of the gel, the top layer of the third layer is put out that the specific gravity is relatively to ninth is determined to be formed only in a small acrylic gel.

본 발명의 아크릴계 조성물이 크랙에 인젝션된 다음 시간이 경과함에 따라 산화제수용액에 함유된 수분이 증발되며, 이로 인하여 아크릴겔로 된 제3층(3)에서는 체적비로 70%, 제2층에서는 50%, 제1층에서는 체적 감소를 보였다. The moisture contained in the oxidizing agent aqueous solution is evaporated as the acrylic composition according to the present invention the following time injection to crack lapse, which in due to the third layer (3) with an acrylic gel of 70%, in the second layer and 50% by volume in the first layer it showed a volume reduction. 그러나, 물이 유입될 때, 상기한 바와같이 아크릴겔의 수분 흡수로 인하여 감소된 체적이 회복되는 것으로 나타났다. However, appeared to be when the water is flowing, the reduced volume due to moisture absorption of the acrylic gel recovered as above.

상기한 바와같이 아크릴계 방수액 조성물의 경우 아크릴겔의 수분 증발 및 흡수로 인한 체적 변화가 발생됨에 따라 종래의 아크릴계 방수액에 의한 방수도막에서 장기간 사용시 방수도막의 체적 감소 및 팽창으로 인한 방수 효과가 저하되는 문제가 있었지만, 본 발명의 아크릴계 방수액 조성물에 의한 방수 도막의 경우 최상층인 제3층과 제2층에서는 상대적으로 아크릴겔에서의 수분의 증발과 흡수로 인한 체적 변화가 있지만 콘크리트와 접착된 기저층인 제1층에는 주로 마이크로시멘트로 이루어져 체적 변화가 10% 정도로 극히 적어 안정됨을 보였다. Problems with the water resistant effects due to long-term volume reduction and expansion of using water resistant coating film on the water film by a conventional acrylic bangsuaek as the case of the acrylic bangsuaek composition the volume change caused by evaporation of water and absorption of the acrylic gel balsaengdoem lowered as described above, is but, in the case of the waterproof film by acrylic bangsuaek composition of the present invention, the top layer of the third layer and the second layer is relatively, but the volume change due to evaporation and absorption of water in the acrylic gel of the concrete and the adhesive base layer of claim 1 layer was mainly composed of stabilized extremely less so the volume change of 10% in micro-cement.

본 발명의 아크릴계 방수액에 의한 방수도막의 압축강도는 평탄한 콘크리트 표면에 방수도막을 시공하였을 때 시공 1일 경과시 12.2MPa, 3일 경과후 29.9 , 7일 경과후 41.2 , 28일 경과후 52.3을 나타내어 압축강도가 증진되어 방수막의 내구성이 향상되고, KSF2322:2000에 의한 투수시험 결과 투수가 되지 않는 것으로 나타났다. The compressive strength of the waterproof film by acrylic bangsuaek of the present invention after 1 day elapsed during 12.2MPa, 3 days have passed since the construction when the construction of water resistant coating film on a flat concrete surface 29.9, and after 7 days exhibits a 41.2, 52.3 after 28 days is increase the compressive strength durable waterproof film can be improved, KSF2322: it was found that is not a permeability test results permeability by 2000.

본 발명은 콘크리트 구조물용 방수 시공을 위한 방수액으로, 특히 콘크리트 구조물의 사용연한 경과에 따라 발생되는 크랙의 방수 시공에 효과적이고 효율적으로 방수시공을 할 수 있다.
