More specifically, it provides an eco-friendly adsorption fiber sheet that can obtain a carbon reduction function and is neutral to slightly alkaline. It relates to a waterproofing coating material that has the function of preventing neutralization of concrete by applying a waterproofing material and at the same time efficiently controlling the moisture contained in the concrete by injecting a moisture absorbent into the perforated hole, and a composite waterproofing method using the same.
일반적으로 콘크리트는 pH 11 내지 12 수준의 알카리성을 유지해야 본연의 기능을 제공할 수 있는데, 콘크리트의 표면의 습기가 공기 중의 이산화탄소를 흡수하여 콘크리트에 포함된 수산화칼슘이 탄산칼슘으로 변하면서 고유의 알칼리성을 잃거나 감소하는 현상을 콘크리트 중성화(카보네이션)라 한다.In general, concrete must maintain an alkalinity of pH 11 to 12 to provide its original function. Moisture on the surface of the concrete absorbs carbon dioxide in the air, and the calcium hydroxide contained in the concrete changes into calcium carbonate, reducing its inherent alkalinity. The phenomenon of loss or reduction is called concrete neutralization (carbonation).
이와 같이 콘크리트가 중성화 과정을 거치면, 철근 부식, 내구성 및 강도 저하 등의 문제가 발생한다.When concrete goes through a neutralization process like this, problems such as corrosion of reinforcing bars and decreased durability and strength occur.
더욱이, 방수를 위해 널리 사용되는 방수 도막재는 pH 4 내지 5 가량의 약산성을 띠는 경우가 많아 이를 콘크리트 표면에 도포하면 콘크리트의 중성화를 가속하는 문제가 따를 수 있다. Moreover, waterproofing coating materials widely used for waterproofing often have a slightly acidic pH of about 4 to 5, so applying them to the concrete surface may cause the problem of accelerating neutralization of the concrete.
또한 콘크리트는 기본적인 함유 수분이 존재하는데, 이를 무시하고 설계된 방수용 도막재(방수층)가 빗물이 콘크리트 표면으로 유입되는 것만 막는 데 치중하면 방수층 내부와 외부의 기압 차로 인해 결로가 발생하고 이를 통해 잔류한 수분이 동절기에 팽창하면서 방수층을 파손할 위험성을 초래할 수 있다.In addition, concrete contains basic moisture, but if the designed waterproofing coating material (waterproof layer) ignores this and focuses only on preventing rainwater from flowing into the concrete surface, condensation occurs due to the difference in air pressure between the inside and outside of the waterproof layer, and the remaining moisture is lost through this. As it expands during the winter, there is a risk of damaging the waterproof layer.

이하 첨부된 도면을 참조하여 본 발명의 바람직한 실시예를 상세하게 설명하도록 한다. 첨부된 도면은 축척에 의하여 도시되지 않았으며, 각 도면의 동일한 참조 번호는 동일한 구성 요소를 지칭한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. The accompanying drawings are not drawn to scale, and like reference numbers in each drawing refer to like elements.
도 1은 본 발명의 복합 방수 공법의 기본적인 공정을 도시한 순서도이다.Figure 1 is a flowchart showing the basic process of the composite waterproofing method of the present invention.
도 1을 보아 알 수 있듯이, 본 발명의 복합 방수 공법은 제 1 단계(S11), 제 2 단계(S12), 제 3 단계(S13), 제 4 단계(S14), 제 5 단계(S15) 및 제 6 단계(S16)을 포함하는 것을 특징으로 한다.As can be seen from Figure 1, the composite waterproofing method of the present invention includes the first step (S11), the second step (S12), the third step (S13), the fourth step (S14), the fifth step (S15), and It is characterized by including a sixth step (S16).
(S11) 제 1 단계(S11) Step 1
우선, 건축물이나 구조물의 외면에서 방수 공법이 이루어질 대상면, 즉 콘크리트의 표면의 불순물을 제거하기 위한 세척 공정을 거친다. 이때, 고르지 못한 콘크리트의 표면을 평탄하게 정리하는 과정이 동반될 수 있다. First, the exterior of a building or structure undergoes a cleaning process to remove impurities from the surface of the concrete, which is the surface where waterproofing will be done. At this time, the process of smoothing out the uneven surface of concrete may be accompanied.
여기서 불순물은 콘크리트의 표면에 붙어 있을 수 있는 먼지, 자갈, 기름 따위의 이물질을 지칭하고, 세척 과정은 불순물을 제거하기 위한 블로잉, 브러싱 등의 다양한 방법이 포함될 수 있으나 바람직하게는 과량의 물 또는 기타 세정용 액상을 이용하여 콘크리트의 표면을 세척하는 과정을 포함할 수 있다.Here, impurities refer to foreign substances such as dust, gravel, and oil that may be attached to the surface of concrete, and the cleaning process may include various methods such as blowing or brushing to remove impurities, but is preferably washed with excess water or other methods. It may include a process of cleaning the surface of concrete using a cleaning liquid.
이후, 세척된 콘크리트의 표면에 프라이머를 도포하는 과정을 거친다.Afterwards, a primer is applied to the surface of the cleaned concrete.
프라이머는 후술할 1차 방수층 및 기타 조성이 콘크리트에 더욱 안정적으로 부착/접착될 수 있는 기반을 조성함과 아울러 콘크리트 표면의 미세한 불완정성, 기공, 마이크로 크랙을 실링 처리함과 동시에 outgassing(콘크리트의 함유 수분을 방출하여 방수층에 기포가 발생하는 현상)을 감소하는 기능을 제공한다.The primer creates a base on which the primary waterproofing layer and other compositions to be described later can be more stably attached/adhered to concrete, and also seals fine imperfections, pores, and micro-cracks on the concrete surface, while outgassing (containing concrete). It provides the function of reducing the phenomenon of bubbles forming in the waterproof layer by releasing moisture.
이러한 프라이머는 아크릴/에폭시/폴리우레탄/실란 기반의 다양한 종류가 적용될 수 있고, 본 발명에서는 특별히 한정되지 않고 후술할 1차 방수층 및 흡착 섬유 시트의 조성/재질에 따라 선택될 수 있다.These primers may be of various types based on acrylic/epoxy/polyurethane/silane, and are not particularly limited in the present invention and may be selected depending on the composition/material of the primary waterproof layer and the adsorbent fiber sheet, which will be described later.
(S12) 제 2 단계(S12) Step 2
제 2 단계는 방수재를 도포하여 1차 방수층을 형성하는 단계이다.The second step is to apply a waterproofing material to form a primary waterproofing layer.
본 발명에서는 2번의 방수재 도포 공정을 포함하므로 첫 번째로 방수재가 도포되어 형성되는 방수층을 1차 방수층이라 명명한다.Since the present invention includes two waterproofing material application processes, the waterproofing layer formed by applying the waterproofing material first is called the primary waterproofing layer.
1차 방수층은 물론 후술할 2차 방수층의 재질이라 할 수 있는 방수재는 기본적으로 산성이나 약산성을 띠지 않고 중성에서 약알칼리성을 가진 물질, 구체적으로 pH 7 내지 8로 이루어지도록 한다.The waterproofing material, which can be said to be the material of the primary waterproofing layer as well as the secondary waterproofing layer to be described later, is basically not acidic or slightly acidic but is made of a neutral to slightly alkaline material, specifically pH 7 to 8.
이러한 방수재는 예를 들어 통기성을 확보할 수 있는 실록산 또는 실란 기반의 물질이거나 물과 잘 섞이면서 통기성을 겸비한 아크릴 계면활성제, 광택을 낼 수 있는 수성 에폭시, 방수 성능은 물론 단열 기능을 제공하는 세라믹 기반의 물질 중 어느 하나로 이루어질 수 있고, 더 나아가 후술하겠지만 본 발명에서는 독특한 혼합물을 방수재로 제공할 수 있다.These waterproofing materials are, for example, siloxane- or silane-based materials that ensure breathability, acrylic surfactants that mix well with water and are breathable, water-based epoxies that can be polished, and ceramic-based materials that provide insulation as well as waterproofing properties. It can be made of any one of the materials, and as will be further described later, the present invention can provide a unique mixture as a waterproofing material.
(S13) 제 3 단계(S13) Step 3
제 3 단계는 1차 방수층의 표면에 흡착 섬유 시트를 부착하여 기초층을 완성하는 단계이다.The third step is to complete the base layer by attaching an adsorption fiber sheet to the surface of the first waterproofing layer.
본 발명에서 '기초층'은 제 2,3 단계에 의해 적층된 2개의 층 구조를 의미하는 것으로서, 1차 방수층과 흡착 섬유 시트가 적층된 층들을 의미한다.In the present invention, 'base layer' refers to a two-layer structure laminated in the second and third steps, and refers to layers in which a primary waterproof layer and an adsorbent fiber sheet are laminated.
흡착 섬유 시트는 화학적으로 안정성을 가지면서 1차 방수층의 방수재를 흡착할 수 있는 성질을 제공하는 것으로서, 방수재를 흡착하여 일종의 저장소와 같은 역할을 제공하여 지속적으로 방수재의 방수 성능을 발현하면서 방수 기능을 장시간 유지할 수 있는 특성을 제공한다.The adsorption fiber sheet is chemically stable and provides the ability to adsorb the waterproofing material of the primary waterproofing layer. It adsorbs the waterproofing material and acts as a kind of reservoir, continuously expressing the waterproofing performance of the waterproofing material and maintaining the waterproofing function. It provides characteristics that can be maintained for a long time.
더불어 흡착 섬유 시트는 1차 방수층의 부식을 막는 물리적 역할을 가질 뿐 아니라 유연성을 제공하여 구조적 결함이 발생할 위험을 줄이는 한편, 1차 방수층에서 방수재가 특정 영역에 집중되는 현상을 방지하며 1차 방수층의 균일성을 보장하는 기능을 수행함과 아울러, 무엇보다 콘크리트 내부의 습도를 조절하여 해당 습기로 인하여 콘크리트가 손상되는 것을 방지하는 콘크리트의 함유 수분 제어 기능을 겸비한다.In addition, the adsorbent fiber sheet not only has a physical role in preventing corrosion of the primary waterproofing layer, but also reduces the risk of structural defects by providing flexibility. It also prevents the concentration of waterproofing materials in a specific area in the primary waterproofing layer and protects the primary waterproofing layer. In addition to performing the function of ensuring uniformity, it also has the function of controlling the moisture contained in the concrete by controlling the humidity inside the concrete to prevent damage to the concrete due to the moisture.
이러한 흡착 섬유 시트는 예를 들어 물에 대한 저항성이 좋고 화학적 안정성을 가진 폴리프로필렌(PP) 또는 방수재와의 우수한 호환성을 가진 폴리아크릴론리트릴(PAN)이거나 나무 펄프에서 생성된 인공 섬유로서 우수한 수분 흡수 성능을 발현할 수 있는 비스코스로 이루어진 상태에서 니덜 펀칭 공법으로 제작하여 자체 중량 대비 최대 20배의 방수재를 흡수할 수 있는 성능을 제공하는 것이 가능하다.These adsorbent fiber sheets are, for example, polypropylene (PP), which has good water resistance and chemical stability, or polyacrylon lithrile (PAN), which has good compatibility with waterproofing materials, or is an artificial fiber produced from wood pulp and has excellent moisture absorption. It is possible to provide performance that can absorb up to 20 times the waterproofing material compared to its own weight by manufacturing it using the needle punching method while made of viscose that can demonstrate performance.
이러한 흡착 섬유 시트는 친환경 재질을 가져 탄소 저감 기능을 제공할 수 있음은 물론인데, 예를 들어 100 내지 300g 중량의 흡착 섬유 시트는 직포 공정을 거치지 않고 부정 방향으로 배열한 상태에서 하단은 저온 열가압 처리하여 저밀도를 가져 1차 방수층의 흡착력을 강화함과 아울러 콘크리트의 습도 조절 기능과 유연성을 확보하되 상단은 고온 가압하여 고밀도를 가짐으로써 내구성과 1차 방수층 보호 기능을 증강할 수 있다.Of course, these adsorption fiber sheets are made of eco-friendly materials and can provide a carbon reduction function. For example, an adsorption fiber sheet weighing 100 to 300 g is arranged in an irregular direction without going through a woven process, and the bottom is heat-pressed at low temperature. By treating it to a low density, it strengthens the adsorption power of the primary waterproofing layer and secures the humidity control function and flexibility of concrete, but the upper part is high-temperature and pressurized to have a high density, thereby enhancing durability and the protection function of the primary waterproofing layer.
도 2는 콘크리트에 타공된 홀에 흡습제가 주입된 도막재의 전체 구조를 예시한 단면도이다.Figure 2 is a cross-sectional view illustrating the overall structure of a coating material in which a moisture absorbent is injected into a hole perforated in concrete.
(S14) 제 4 단계(S14) Step 4
제 4 단계는 기초층 및 콘크리트 표면으로부터 일정 깊이와 직경을 가진 홀을 타공하는 단계이다.The fourth step is to drill holes with a certain depth and diameter from the foundation layer and concrete surface.
이러한 홀은 후술할 흡착제가 주입될 수 있는 공간을 제공하는 것으로서, 콘크리트의 전체 면적에 따라 홀의 개수는 물론 깊이와 직경을 조절할 수 있되 최소한 5cm 이상의 깊이는 확보하여 콘크리트 내부의 수분을 제어할 수 있는 환경을 조성하는 것이 바람직하다.These holes provide a space into which the adsorbent, which will be described later, can be injected. The number of holes as well as the depth and diameter can be adjusted according to the total area of the concrete, and the moisture inside the concrete can be controlled by ensuring a depth of at least 5 cm or more. It is desirable to create an environment.
즉 도 2에서는 홀이 1개만 도시되었으나, 반드시 이에 한정되는 것은 아니고 2개 이상의 복수 개로 타공 형성되는 것도 물론 가능하다.That is, although only one hole is shown in FIG. 2, it is not necessarily limited to this, and it is of course possible to form two or more holes.
(S15) 제 5 단계(S15) Step 5
제 5 단계는 홀에 흡습제를 주입하는 단계를 의미한다.The fifth step refers to the step of injecting the moisture absorbent into the hole.
도 2를 보아 알 수 있듯이, 본 발명의 흡습제는 홀에 주입/충진된 상태에서 노후화된 콘크리트에 포함된 수분을 흡수하여 팽창하는 성질을 제공하는 것으로서, 기본적으로 폴리아크릴아미드(Polyacrylamide, PAM)를 포함한다.As can be seen from Figure 2, the moisture absorbent of the present invention provides the property of absorbing moisture contained in aged concrete and expanding when injected/filled into the hole, and is basically polyacrylamide (PAM). Includes.
폴리아크릴아미드는 수용성 고분자로서 물을 흡수하는 능력이 뛰어나 유아용 기저귀 또는 토양의 수분 보존을 향상하기 위해 사용되는 농업 용제로 사용되고 있다.Polyacrylamide is a water-soluble polymer that has an excellent ability to absorb water and is used as a baby diaper or agricultural solvent to improve soil moisture retention.
특히 본 발명의 폴리아크릴아미드는 가교, 즉 크로스링크(cross-linking) 처리되어 자신의 질량보다 수십 배에서 수백 배에 이르는 물, 즉 수분을 흡수할 수 있는 성질을 가지면서 노후화된 콘크리트의 수분을 흡수하여 상술한 흡착 섬유 시트 이상으로 콘크리트에 함유된 수분을 제어하는 기능을 제공할 수 있다.In particular, the polyacrylamide of the present invention is cross-linked and has the property of absorbing water, i.e., tens to hundreds of times its own mass, and is capable of absorbing moisture from aged concrete. By absorbing moisture, it can provide a function to control moisture contained in concrete beyond the above-mentioned adsorbent fiber sheet.
즉, 흡습제는 수분을 흡수하여 팽창하는 성질을 기반으로 콘크리트에 불필요하게 포함된 수분을 탁월하게 흡수하는 성능을 발휘하면서 본 발명의 특징인 콘크리트 함유 수분 제어 기능을 제공하는 핵심적인 기능을 제공한다. In other words, the desiccant has the ability to absorb moisture unnecessarily contained in concrete based on its ability to absorb moisture and expand, while providing a key function of controlling moisture contained in concrete, which is a feature of the present invention.
(S16) 제 6 단계(S16) Step 6
제 5 단계는 기초층 즉, 흡착 섬유 시트의 표면에 1차 방수층을 형성하는 방수재와 동일한 방수재를 다시 도포하여 2차 방수층을 형성하는 단계이다.The fifth step is to form a secondary waterproof layer by re-applying the same waterproofing material as that forming the primary waterproofing layer on the surface of the base layer, that is, the adsorbent fiber sheet.
즉, 2차 방수층은 흡착 섬유 시트가 외부로 노출되는 것을 방지하면서 재차 방수 기능을 제공하는바, 이러한 2차 방수층은 1차 방수층(1차 방수층의 상단)보다 고밀도로 제작되어 기초층을 보호하면서 본 발명의 도막재에 대한 전반적인 내구성을 강화하는 것이 가능하다.In other words, the secondary waterproofing layer prevents the adsorbent fiber sheet from being exposed to the outside and provides a waterproofing function again. This secondary waterproofing layer is manufactured at a higher density than the primary waterproofing layer (the top of the primary waterproofing layer) to protect the base layer while protecting the base layer. It is possible to enhance the overall durability of the coating material of the present invention.
이후, 2차 방수층 상에 공지의 탑코팅층을 코팅하면서 본 발명의 도막재를 완성할 수 있다.Thereafter, the coating material of the present invention can be completed by coating a known top coating layer on the secondary waterproofing layer.
도 3은 본 발명의 도막재에 대한 성능을 나타낸 표이다.Figure 3 is a table showing the performance of the coating material of the present invention.
도 3에 도시된 성능은 표를 표 1,2로 다시 표현하면 다음과 같이 구체화된다.The performance shown in Figure 3 is specified as follows if the table is rephrased as Tables 1 and 2.
(KS 기준)(based on KS)
(KS 기준)(based on KS)
도 3 및 표 1,2를 보아 알 수 있듯이 상술한 공정을 거쳐 완성된 도막재는 중성화 침투 저항성 및 투습도와 내투수성, 균열 대용성에 대한 기준치를 통과하는 것은 물론 인장강도와 부착강도 역시 기준치 이상의 우수한 성능을 발휘하는 특성을 제공하는 것이 가능하다.As can be seen from Figure 3 and Tables 1 and 2, the coating material completed through the above-described process not only passes the standard values for neutralization penetration resistance, moisture permeability, water permeability resistance, and crack resistance, but also has tensile strength and adhesion strength that are superior to the standard values. It is possible to provide performance characteristics.
추가로 상술한 방수재는 에틸렌비닐아세테이트 50 내지 65 중량부와 아크릴 에멀젼 수지 15 내지 20 중량부 및 폴리비닐아세테이트 10 내지 15 중량부를 포함한 혼합물을 pH 7 내지 8로 조절하여 제조되는 것이 바람직하다.In addition, the above-described waterproofing material is preferably manufactured by adjusting the pH to 7 to 8 of a mixture containing 50 to 65 parts by weight of ethylene vinyl acetate, 15 to 20 parts by weight of acrylic emulsion resin, and 10 to 15 parts by weight of polyvinylacetate.
에틸렌비닐아세테이트(Ethylene Vinyl Acetate, EVA)는 유연성과 부드러움을 제공하는 기반에서 물에 대한 저항성, 즉 방수성을 발휘하는 기능을 제공한다. 이러한 성질에 의하여 균열이 발생하기 쉬운 콘크리트 표면에 접착 및 부착 성능을 향상하는 특성을 가질 수 있다. Ethylene Vinyl Acetate (EVA) provides water resistance, that is, waterproofing, on the basis of flexibility and softness. Due to these properties, it can have properties that improve adhesion and adhesion performance to concrete surfaces that are prone to cracks.
아크릴 에멀젼 수지(Acrylic Emulsion Resin)는 뛰어난 접착력, UV 안정성, 내후성을 가진 상태에서 물에 대한 저항성, 즉 방수성을 제공한다.Acrylic Emulsion Resin provides water resistance, that is, waterproofing, while having excellent adhesion, UV stability, and weather resistance.
이러한 성질을 기반으로 에틸렌비닐아세테이트와 마찬가지로 균열이 발생하기 쉬운 콘크리트 표면에 접착 및 부착 성능을 향상하는 특성을 제공함과 아울러, UV 안정성에 기인하여 외부광에 노출된 콘크리트의 변성을 막을 수 있는 기능을 겸비할 수 있다.Based on these properties, it provides properties that improve adhesion and adhesion performance to concrete surfaces that are prone to cracks, similar to ethylene vinyl acetate, and also has the ability to prevent deterioration of concrete exposed to external light due to UV stability. It can be combined.
폴리비닐아세테이트(Polyvinyl Acetate, PVA) 역시 우수한 방수성을 가진 상태에서 특히 뛰어난 접착 성능을 제공하여 본 발명의 도막재에 대한 전반적인 접착성을 강화하는 특성을 제공하고, 가교 처리하면서 접착성을 개선하는 것도 가능하다. Polyvinyl Acetate (PVA) also provides particularly excellent adhesion performance while having excellent waterproofing properties, providing properties that strengthen the overall adhesion to the coating material of the present invention, and also improves adhesion during crosslinking. possible.
이와 같은 혼합물이 pH 7 내지 8의 중성 내지 약알칼리성을 가지도록 함으로써 콘크리트에 대한 호환성과 안정성을 담보하는 특성을 제공할 수 있다.By ensuring that such a mixture has a neutral to slightly alkaline pH of 7 to 8, it can provide properties that ensure compatibility and stability for concrete.
더 나아가, 상술한 흡습제는 폴리아크릴아미드 이외에 추가의 조성을 포함하는 것이 가능하다.Furthermore, it is possible for the above-mentioned moisture absorbent to contain additional compositions other than polyacrylamide.
구체적으로, 흡습제는 상술한 폴리아크릴아미드를 포함하는 베이스 40 내지 60 중량부와, 다이나트륨 페록시디설페이트(Disodium peroxydisulfate)를 포함하는 가교제 40 내지 60 중량부를 포함하는 것이 가능하다.Specifically, the moisture absorbent may include 40 to 60 parts by weight of a base containing the above-described polyacrylamide and 40 to 60 parts by weight of a crosslinking agent containing disodium peroxydisulfate.
앞서 언급하였듯이 폴리아크릴아미드는 가교 처리되어 수용성 겔을 형성하였을 때 상술한 우수한 팽창 성질을 가질 수 있는바, 가교제가 이같인 폴리아크릴아미드의 가교 처리를 수행하도록 한다.As mentioned earlier, polyacrylamide can have the above-mentioned excellent swelling properties when cross-linked to form a water-soluble gel, and a cross-linking agent is used to perform the cross-linking treatment of polyacrylamide.
가교제는 가교제 전체 100 중량부를 기준으로, 다이나트륨 페록시디설페이트 3 내지 5 중량부와 물 90 내지 95 중량부를 포함할 수 있다. The crosslinking agent may include 3 to 5 parts by weight of disodium peroxydisulfate and 90 to 95 parts by weight of water, based on 100 parts by weight of the total crosslinking agent.
이때 다이나트륨 페록시디설페이트는 폴리아크릴아미드의 중합과 크로스링킹을 개시하는 가교 역할을 제공하고, 물은 흡습제가 일반적으로 가교 처리된 폴리아크릴아미드만으로 이루어진 경우보다 훨씬 높은 점도를 가질 수 있는 기반을 제공하여 안정성을 유지하면서 콘크리트의 수분 흡수 및 제어 기능을 촉진할 수 있는 기능을 제공할 수 있다.At this time, disodium peroxydisulfate provides a cross-linking role that initiates the polymerization and cross-linking of polyacrylamide, and water provides a basis for the moisture absorbent to have a much higher viscosity than when it is composed only of generally cross-linked polyacrylamide. This can provide a function that promotes the moisture absorption and control function of concrete while maintaining stability.
더불어, 베이스는 폴리아크릴아미드 20 내지 40 중량부와, 수산화나트륨(Sodium Hydroxide) 3 내지 5 중량부 및, 벤조일퍼옥사이드(Benzoyl Peroxide) 5 내지 8 중량부와 물 60 내지 70 중량부로 이루어지는 것이 가능하다.In addition, the base may be composed of 20 to 40 parts by weight of polyacrylamide, 3 to 5 parts by weight of sodium hydroxide, 5 to 8 parts by weight of benzoyl peroxide, and 60 to 70 parts by weight of water. .
수산화나트륨은 물에 용해되면서 pH를 높이는 기능을 제공하는 것으로서, 흡습제가 알칼리성을 가질 수 있도록 pH를 조절하는 것은 물론 후술할 벤조일퍼옥사이드와 함께 상술한 폴리아크릴아미드와 가교제 간의 가교 반응을 안정적으로 수행할 수 있는 환경을 조성한다.Sodium hydroxide provides the function of raising pH by dissolving in water. It not only adjusts the pH so that the desiccant becomes alkaline, but also stably performs the crosslinking reaction between the polyacrylamide and the crosslinking agent described above along with benzoyl peroxide, which will be described later. Create an environment where this can be done.
벤조일퍼옥사이드는 강력한 산화제로서 폴리아크릴아미드와 가교제 간의 가교 반응의 시작제로서의 촉매 역할을 제공한다.Benzoyl peroxide is a strong oxidizing agent and serves as a catalyst initiating the crosslinking reaction between polyacrylamide and the crosslinking agent.
특히 벤조일퍼옥사이드는 상술한 수산화나트륨의 존재 하에서 가교 반응을 더욱 촉진할 수 있다.In particular, benzoyl peroxide can further promote the crosslinking reaction in the presence of the above-mentioned sodium hydroxide.
물은 용매로서 폴리아크릴아미드, 수산화나트륨 및 벤조일 퍼옥사이드를 용해하는 것은 물론 폴리아크릴아미드의 겔화를 촉진하는 역할을 수행한다.As a solvent, water not only dissolves polyacrylamide, sodium hydroxide, and benzoyl peroxide, but also promotes gelation of polyacrylamide.
이러한 베이스의 성분에 의하여 상술한 가교제와 폴리아크릴아미드 간의 가교 반응을 촉진하면서 흡습제 전반의 알칼리성을 유지할 수 있는 특성을 겸비할 수 있다.This base component can promote the crosslinking reaction between the above-mentioned crosslinking agent and polyacrylamide while maintaining the alkalinity of the entire moisture absorbent.
도 4는 홀에 서포트 가이드가 형성된 구조를 도시한 단면도이다.Figure 4 is a cross-sectional view showing a structure in which a support guide is formed in a hole.
도 4를 보아 알 수 있듯이, 홀의 중공에는 서포트 가이드가 수용되는 것이 가능하다.As can be seen from Figure 4, it is possible for a support guide to be accommodated in the hollow of the hole.
서포트 가이드는 홀의 상부에서 하부까지의 길이 방향을 따라 연장된 상태에서 코어와 실링재로 구성된다. The support guide extends along the longitudinal direction from the top to the bottom of the hole and is composed of a core and a sealing material.
코어는 후술할 실링재를 지탱하는 기능을 제공하는 것으로, 강성이 있는 금속재로 제작되는 것이 가능하다.The core provides the function of supporting the sealing material, which will be described later, and can be made of a rigid metal material.
이러한 코어는 실링재를 지지하는 기능을 제공하는 것은 물론, 홀의 바닥에 접착제나 기타 고정 수단을 매개로 고정되어 홀 내부에서 유동되지 않고 안정적으로 기립될 수 있도록 설치되는 것이 중요하다.It is important that this core not only provides the function of supporting the sealing material, but is also fixed to the bottom of the hole using adhesive or other fixing means so that it can stand stably without flowing inside the hole.
실링재는 상술한 흡착 섬유 시트와 동일한 재질로 이루어진 상태에서 코어를 감싸는 부재이다.The sealing material is a member that surrounds the core and is made of the same material as the above-mentioned adsorption fiber sheet.
이러한 서포트 가이드가 홀에 수용된 상태에서, 흡습제가 실링재를 적시면서 홀에 주입된다.With this support guide accommodated in the hole, the moisture absorbent is injected into the hole while moistening the sealing material.
이러한 서포트 가이드는 홀에 주입된 흡습제가 중력에 의하여 홀의 상부보다 하부에 편중되거나 침전되어 홀의 상부 주변의 콘크리트의 수분을 제어하지 못하는 문제를 효율적이고 물리적으로 방지하는 기능을 제공한다.This support guide provides a function to efficiently and physically prevent the problem of the moisture absorbent injected into the hole being concentrated or settled in the lower part of the hole rather than the upper part due to gravity, thereby failing to control moisture in the concrete around the upper part of the hole.
즉, 서포터 가이드의 높이 전반에 걸쳐서 실링 처리된 실링재에 흡수제가 묻은 상태에서 흡수제로 하여금 홀의 상부는 물론 중부, 하부에 걸쳐 고르게 콘크리트의 함유 수분을 흡수할 수 있어, 결과적으로 홀의 상단/하단에서 발생할 수 있는 불균일한 흡수성을 균일하게 조절할 수 있는 특성을 부여할 수 있다.In other words, when the absorbent is applied to the sealing material that has been sealed throughout the height of the supporter guide, the absorbent can absorb the moisture contained in the concrete evenly throughout the upper part of the hole as well as the middle and lower parts, resulting in the occurrence of moisture at the top/bottom of the hole. It can provide properties that can uniformly control uneven absorbency.
더불어, 콘크리트의 수분을 충분히 흡수한 서포트 가이드를 쉽게 교체할 수 있는 편의성을 제공할 뿐 아니라 실링재를 매개로 흡습제가 콘크리트의 수분을 과다하게 흡수하는 현상을 줄이면서 흡수량을 효율적으로 조절할 수 있는 특성을 겸비하는 것이 가능하다.
지금까지 설명한 바와 같이, 본 발명에 따른 콘크리트 함유 수분 제어 기능을 포함한 탄소 저감 기반의 친환경 도막재 및 이의 복합 방수 공법의 구성 및 작용을 상기 설명 및 도면에 표현하였지만 이는 예를 들어 설명한 것에 불과하여 본 발명의 사상이 상기 설명 및 도면에 한정되지 않으며, 본 발명의 기술적 사상을 벗어나지 않는 범위 내에서 다양한 변화 및 변경이 가능함은 물론이다.In addition, it not only provides the convenience of easily replacing the support guide that has sufficiently absorbed the moisture of the concrete, but also reduces the phenomenon of the moisture absorbent absorbing excessive moisture from the concrete through the sealing material and has the property of efficiently controlling the amount of absorption. It is possible to combine.
As explained so far, the configuration and operation of the carbon reduction-based eco-friendly coating material and its composite waterproofing method including the moisture control function contained in concrete according to the present invention are expressed in the description and drawings, but this is only an example. The spirit of the invention is not limited to the above description and drawings, and of course, various changes and modifications are possible without departing from the technical spirit of the invention.
