Description
본 발명은 규산질계 분말형 도포 방수제에 관한 것으로서, 더욱 상세하게는 건물의 옥상이나 기타 토목 구조물의 콘크리트면에 도포하여 물을 차단할 수 있는 유·무기 혼합형 규산질계 분말형 도포 방수제에 관한 것이다.The present invention relates to a siliceous powder coating waterproofing agent, and more particularly, to an organic / inorganic mixed siliceous powder coating waterproofing agent which can be applied to a concrete surface of a roof of a building or other civil structures to block water.
최근 토목분야를 중심으로 도포방수제라 칭하는 구체방수제(軀體防水濟)의 수요가 증가하고 있다. 이러한 방수제는 콘크리트면에 타설하여 구체(驅體)에 무기질 분말이 도포되도록 하는 것이나, 지하 3층 이상, 즉 3kg/㎡ 이상의 압력을 받는 곳에서는 방수 효과가 현저히 떨어지며, 또 한편으로 철근을 부식시키고 건조수축이 크게 발생하는 단점이 있으므로 이의 사용에 주의를 기울여야 한다. 이같은 문제점은 특히 겨울철 시공시에 더욱 큰 문제점으로 대두된다.Recently, the demand for concrete waterproofing agents called coating waterproofing agents is increasing mainly in the civil engineering field. This waterproofing agent is to be sprayed on the concrete surface so that inorganic powder is applied to the sphere. However, the waterproofing effect is remarkably decreased in the place where the pressure is more than 3 stories underground, that is, more than 3kg / ㎡, and the corrosion of the rebar is on the other hand. Attention should be paid to the use of dry shrinkage because of its disadvantage. This problem is especially serious in winter construction.
이러한 문제점을 개선하고자 본 발명자들은 침투성이 매우 우수하고 내식성이 있는 무기질 방수제 조성물에 대하여 출원하였고, 기 특허되었다(대한민국 특허 제95242호).In order to improve this problem, the present inventors have filed and patented an inorganic waterproofing agent composition having excellent permeability and corrosion resistance (Korean Patent No. 95242).
상기의 무기질 방수제 조성물은 시멘트 50∼100 중량부, 고운 모래 30∼50 중량부, 미세한 판유리 분말 10∼15 중량부, 소량의 계면활성제 및 포졸라나를 혼합하여 이루어진 것이다.The inorganic waterproofing agent composition is made by mixing 50 to 100 parts by weight of cement, 30 to 50 parts by weight of fine sand, 10 to 15 parts by weight of fine plate glass powder, a small amount of surfactant and pozzolana.
이같은 무기질 방수제는 내식성, 흡수비 및 투수비를 향상시켜 침투성이 매우 우수하고 내식성이 우수하다.Such inorganic waterproofing agent improves corrosion resistance, absorption ratio, and permeability ratio, thereby having excellent permeability and excellent corrosion resistance.
상기와 같은 규산질계 분말형 도포방수제 조성물은 먼저 시멘트와 물에 의해 경화되고, 시멘트 수화시 칼슘하이드록사이드와 같은 염이 발생하게 된다. 그리고, 실리카 성분이 시멘트 수화시 발생한 염과 반응하여 CaO·SiO3와 같은 불용성 결정체를 생성한다. 따라서, 불용성 결정물이 시멘트 공극 사이를 채우게 되므로 우수한 수밀성을 가지며 무기질계 침투성 방수제라는 이름으로 사용되고 있다. 뿐만 아니라 최근 KS규격의 제정으로 사용량이 증가되고 있다.The siliceous-based powder coating waterproofing composition as described above is first hardened by cement and water, and salts such as calcium hydroxide are generated during cement hydration. In addition, the silica component reacts with the salt generated during cement hydration to form insoluble crystals such as CaO.SiO 3 . Therefore, insoluble crystals fill the gaps between the cement pores and have excellent watertightness and are used under the name of inorganic penetrant waterproofing agents. In addition, the usage has increased due to the recent enactment of the KS standard.
그런데, 이와 같이 무기질계로만 이루어진 도포 방수제는 콘크리트 표면에 도포시 시멘트 공극을 채워 방수층을 형성하기 전에 수압의 영향으로 방수층 박리현상이 발생되고 방수층의 취약부위가 발생되는 문제점이 있다.However, as described above, the coating waterproofing agent made of only inorganic type has a problem in that the waterproofing layer peeling phenomenon occurs and the weak part of the waterproofing layer is generated by the influence of water pressure before forming the waterproofing layer by filling the cement voids when the concrete surface is coated.
이에 따라 상기와 같은 규산질계 분말형 도포 방수제의 접착 성능 및 탄성, 흡수비 등의 물성을 보다 향상시킬 필요성이 대두되었다.Accordingly, the necessity of further improving the adhesive properties, elasticity, absorption ratio, and the like of the siliceous-based powder coating waterproofing agent has emerged.
본 발명의 목적은 침투성이 우수한 무기질계 방수제에 아크릴 에멀젼을 첨가함으로써 방수층과 모체의 접착력을 향상시키고, 도포층의 경화시간을 단축시킴으로써 안정적이고, 통기성이 확보되어 방수층 형성후 침투성분의 침투가 용이한 방수제를 제공하는 데 있다.It is an object of the present invention to improve the adhesion between the waterproof layer and the mother by adding an acrylic emulsion to the inorganic waterproofing agent having excellent permeability, and to shorten the curing time of the coating layer, which is stable and breathable to ensure penetration of the penetrating component after forming the waterproofing layer. To provide a waterproofing agent.
이와같은 목적을 달성하기 위한 본 발명의 방수제 조성물은 시멘트 50∼100 중량부, 고운 모래 30∼50 중량부, 미세한 판유리 분말 10∼15 중량부, 알킬나프탈렌 술포네이트계 계면활성제 1∼2 중량부 및 포졸라나 1∼2 중량부로 이루어진 무기질 방수제 100 중량부 및 아크릴산 에스테르계 아크릴 에멀젼 3∼15 중량부로 이루어진 것임을 그 특징으로 한다.The waterproofing agent composition of the present invention for achieving the above object is 50 to 100 parts by weight of cement, 30 to 50 parts by weight of fine sand, 10 to 15 parts by weight of fine glass powder, 1 to 2 parts by weight of alkylnaphthalene sulfonate surfactant and It is characterized by consisting of 100 parts by weight of an inorganic waterproofing agent consisting of 1 to 2 parts by weight of pozzolana and 3 to 15 parts by weight of an acrylic ester-based acrylic emulsion.
이와같은 본 발명을 더욱 상세하게 설명하면 다음과 같다.The present invention will be described in more detail as follows.
전술한 바와 같이 규산질계 분말형 도포방수제는 지하 구조물 등 수압의 영향을 받는 부위에 주로 사용되고 있으나 지하 3층 이상, 즉 3kgf/㎠ 이상의 압력을 받는 곳에서 들뜸 현상과 같이 모체인 지하 구조물로부터 방수층이 형성되기 전 생기는 수압의 영향으로 방수층 박리현상이 발생되고 방수층의 취약 부위가 발생한다.As described above, the siliceous-based powder coating waterproofing agent is mainly used in areas affected by water pressure, such as underground structures. Under the influence of the water pressure generated before the formation of the peeling phenomenon of the waterproofing layer occurs, the weak portion of the waterproofing layer occurs.
본 발명에서는 방수층과 모체의 접착력 향상에 중점을 두었으며, 도포층의 경화시간이 단축되므로 기존의 방수층에서 침투성분의 충분한 침투시까지 모체가 견뎌야 하는 시간을 단축시켜 기존 방수제 보다 안정화되었으며, 무기질계 방수제 로 인해 통기성이 확보되어 통상의 일부 아크릴 에멀젼 첨가 제품이 통기성이 없으므로 방수층 형성후 침투성분의 침투가 되지 않는 점을 보완하고, 통기성, 충격강도, 작업성, 흡수비 등의 방수성능도 향상킬 수 있다.In the present invention, the emphasis was placed on improving the adhesion between the waterproof layer and the mother, and since the curing time of the coating layer is shortened, it is more stable than the existing waterproofing agent by shortening the time the mother has to withstand until sufficient penetration of the penetrating component in the existing waterproof layer. As the waterproofing agent ensures breathability, some of the usual acrylic emulsion-added products are not breathable, which makes it impossible to penetrate the penetrating components after forming the waterproof layer, and also improves the waterproofing performance such as breathability, impact strength, workability, and absorption ratio. Can be.
본 발명에서 이같은 효과를 나타내기 위해 무기질 방수제에 아크릴산 에스테르계 아크릴 에멀젼을 혼합한다.In order to exhibit such an effect in the present invention, an acrylic ester-based acrylic emulsion is mixed with an inorganic waterproofing agent.
이때, 아크릴산 에스테르계 공중합 에멀젼 수지로는 고형분 56±1%, 점도 1000cps, pH 7∼9인 것을 사용하는 바, 이는 내수성, 내알카리성, 시멘트 혼합성이 우수하며, 탄성과 신축성이 있어 모체의 미세한 크랙에 대한 크랙 추종성이 있다.At this time, the acrylic ester copolymer emulsion resin having a solid content of 56 ± 1%, viscosity of 1000cps, pH 7 ~ 9 is used, which is excellent in water resistance, alkali resistance, cement mixing properties, elasticity and elasticity is fine to the mother There is a crack followability to the crack.
결과적으로 아크릴 에멀젼 수지는 방수제와 모체와의 접착력을 향상시킨다.As a result, the acrylic emulsion resin improves the adhesion between the waterproof agent and the parent.
이같은 아크릴산 에스테르계 아크릴 에멀젼을 무기질 방수제 100 중량부에 대하여 3∼15 중량부 첨가하는 바, 만일 그 함량이 3 중량부 미만이면 접착력 향상에 영향을 주지 못하며, 15 중량부 초과면 방수층의 통기성이 떨어져 침투성분의 침투성이 떨어지며 비경제적이다.3 to 15 parts by weight of the acrylic ester-based acrylic emulsion is added to 100 parts by weight of the inorganic waterproofing agent. If the content is less than 3 parts by weight, the adhesion is not improved. If the content is more than 15 parts by weight, the waterproof layer is poorly breathable. Penetration of the penetrating components is poor and uneconomical.
본 발명의 방수제를 구성하는 무기질 방수제는 본 발명자들에 의해 출원되어 기 특허된 것(대한민국 특허 제95242호)이다.The inorganic waterproofing agent constituting the waterproofing agent of the present invention is the one filed and patented by the present inventors (Korean Patent No. 95242).
무기질 방수제를 구성하는 고운 모래는 입도가 균일한 모래를 체가름하여 혼합한 것으로, 입도 50∼500㎛ 범위 내에서 평균입도가 200㎛ 정도인 것을 일컬으며, SiO2성분비가 큰 것, 즉 SiO2의 함량이 30∼40%인 모래를 사용하는 것이 바람직하다.The fine sand constituting the inorganic waterproofing agent is a mixture of sand having a uniform particle size, which is referred to as having an average particle size of about 200 μm within a particle size of 50 to 500 μm, and having a high SiO 2 component ratio, that is, SiO 2. Preference is given to using sand having a content of 30 to 40%.
시멘트로는 통상의 포틀랜트 시멘트를 사용하며, 판유리로는 SiO272.48%, Al2O31.87, CaO 10.79, Na2O 14.17, K2O 0.45 및 FeO 0.21로 이루어진 소다라임 유리(Soda-Line Glass)를 분말화하여 사용한다.As a cement, a conventional portland cement is used. As a plate glass, soda-lime glass (Soda-Line) composed of 72.48% SiO 2 , Al 2 O 3 1.87, CaO 10.79, Na 2 O 14.17, K 2 O 0.45 and FeO 0.21 It is used by powdering glass.
계면활성제로는 알킬나프탈렌 술포네이트계, 바람직하게는 알킬나프탈렌 술포네이트 포름알데히드 축합물을 1∼2 중량부로 사용하고, 포졸라나는 수경시멘트의 재료로 사용되는 화산회로서 이 또한 1∼2 중량부로 사용하는 것이 바람직하다.As surfactant, alkylnaphthalene sulfonate-based, preferably alkylnaphthalene sulfonate formaldehyde condensate is used in 1 to 2 parts by weight, and pozzolana is also used in volcanic ash used as a material for hydraulic cement, and is also used in 1 to 2 parts by weight. It is desirable to.
이들은 시멘트 및 물과의 상용성을 증진시키기 위해 사용하는 것으로 과량 사용하면 모르타르의 경화시간이 길어지고 소량 사용하면 물의 사용량이 증가하여 결국 모르타르의 강도가 떨어지므로 이의 적정 사용에 유의해야 한다.These are used to improve the compatibility with cement and water. When used in excess, the curing time of the mortar increases, and when used in small amounts, the amount of water used increases and eventually the strength of the mortar decreases.
이와같은 무기질 방수제는 통상의 아크릴 에멀젼 첨가제품이 통기성이 없기 때문에 방수층 형성 후 침투가 되지 않는 점을 보완하여 무기질 방수제로 인해 통기성이 확보되므로 아크릴 에멀젼의 침투도 용이하다.The inorganic waterproofing agent supplements the point that the conventional acrylic emulsion-added product is not permeable, and thus does not penetrate after forming the waterproofing layer, thereby ensuring air permeability due to the inorganic waterproofing agent.
결과적으로 본 발명의 방수제는 유·무기 혼합형으로 이루어져 무기질계 방수제의 단점과 유기질계 방수제의 단점을 효율적으로 제어하여 침투성과 접착성을 동시에 향상시킬 수 있다.As a result, the waterproofing agent of the present invention may be made of an organic / inorganic mixed type to efficiently control the disadvantages of the inorganic waterproofing agent and the disadvantages of the organic waterproofing agent, thereby simultaneously improving permeability and adhesion.
본 발명의 방수제를 현장에 시공할 때는 무기질 방수제와 아크릴 dpajfwuus 수지가 혼합되어 있는 제품을 시공시 도포하거나, 현장에서 직접 따로이 제품화된 무기질 방수제와 아크릴 에멀젼 수지를 혼합하여 시공할 수도 있다.When the waterproofing agent of the present invention is installed on-site, the inorganic waterproofing agent and the acrylic dpajfwuus resin may be applied at the time of installation, or the inorganic waterproofing agent and the acrylic emulsion resin which are separately produced on the spot may be mixed.
이하, 본 발명을 실시예에 의거 상세히 설명하면 다음과 같은 바, 본 발명이 실시예에 의해 한정되는 것은 아니다.Hereinafter, the present invention will be described in detail with reference to Examples, but the present invention is not limited by the Examples.
실시예 1∼5 및 비교예 1Examples 1-5 and Comparative Example 1
포틀랜트 시멘트 60 중량부, 고운 모래 45 중량부, 판유리 미세분말 10 중량부, 알킬나프탈렌 술포네이트 및 포졸라나 각각 2 중량부를 균일하게 혼합하여 무기질 방수제를 제조하였다.The inorganic waterproofing agent was prepared by uniformly mixing 60 parts by weight of portland cement, 45 parts by weight of fine sand, 10 parts by weight of plate glass fine powder, 2 parts by weight of alkylnaphthalene sulfonate and pozzolana.
제조된 무기질계 방수제 100 중량부에 아크릴산 에스테르계 아크릴 에멀젼 수지를 다음 표 1에 나타낸 바와 같이 그 함량을 달리하여 첨가하였다.Acrylic acid ester-based acrylic emulsion resin was added to 100 parts by weight of the prepared inorganic waterproofing agent in varying amounts as shown in Table 1 below.
여기서, 아크릴산 에스테르계 아크릴 에멀젼 수지는 고형분 함량 57%이고, 점도 1000cps이며, pH 8인 것이다.Here, the acrylic ester acrylic emulsion resin has a solid content of 57%, a viscosity of 1000 cps, and a pH of 8.
그런 다음, 제조한 무기질 방수제를 물과 1:2의 중량비로 혼합 반죽하여 시편에 타설한 후, KSF 4918의 규산질계 무기질 도포 방수제 시험방법에 의거 성능을 측정한 결과는 다음 표 1과 같다.Then, after mixing the prepared inorganic waterproofing agent with water and mixing in a weight ratio of 1: 2, and placed on the specimen, the results of measuring the performance according to the test method of silicate inorganic coating material of KSF 4918 is shown in Table 1.
상기 표 1의 결과로부터 아크릴 에멀젼 수지의 첨가량이 증가함에 따라 투수비, 흡수량이 낮아지는 것으로 보아 아크릴 에멀젼 수지의 첨가에 따라 방수효과가 향상됨을 알 수 있고, 부착강도, 압축강도는 증가하는 것으로 보아 모체와 방수제와의 접착력이 향상된다는 것을 알 수 있다.From the results of Table 1, it can be seen that as the addition amount of the acrylic emulsion resin increases, the permeability ratio and absorption decrease, so that the waterproofing effect is improved according to the addition of the acrylic emulsion resin, and the adhesion strength and the compressive strength increase. It can be seen that the adhesion between the mother and the waterproofing agent is improved.
이상에서 상세히 설명한 바와 같이, 본 발명에 따라 무기질계 방수제와 아크릴 에멀젼 수지를 혼합하여 이루어진 유·무기 혼합형 규산질계 분말형 도포 방수제는 침투성이 우수하면서도 모체와의 접착력이 향상되어 콘크리트 면과의 통기성이 우수하고, 접착성, 탄성, 내마모성 및 내충격성 등의 방수성능을 향상시킬 수 있으므로 지하 구조물 등 수압의 영향을 받는 부위의 시공에 용이하게 사용할 수 있다.As described in detail above, the organic / inorganic mixed silicate-based powder coating waterproofing agent formed by mixing the inorganic waterproofing agent and the acrylic emulsion resin according to the present invention has excellent permeability but improves adhesion to the mother body, thereby improving air permeability with the concrete surface. Excellent and can improve the waterproof performance, such as adhesion, elasticity, wear resistance and impact resistance, so that it can be easily used for the construction of the site affected by water pressure, such as underground structures.
