Description

연질 고무아스팔트계 도막재와 그 제조방법{Soft rubber-asphalt coating material and the method of manufacturing thereof}Soft rubber-asphalt coating material and the method of manufacturing

본 발명은 기후 여건 변화에 따른 대응성, 균열 추종성, 탄성력 및 신장율이 우수하도록 제조된 연질 고무아스팔트계 도막재와 그 제조방법에 관한 것이다.The present invention relates to a soft rubber asphalt-based coating material and a method for manufacturing the same, which are manufactured to have excellent responsiveness, crack followability, elastic force, and elongation rate according to climate change.

건축 구조물의 방수는 건축 총 공사비의 1~3% 이하로 금액적인 측면에서는 미비한 부분을 차지하고 있으나, 실거주자의 쾌적한 주거 환경의 유지라는 환경적 측면 뿐만 아니라 누수로 인한 철근 및 철골의 부식, 중성화, 동결융해, 유해 물질의 침입 등으로 인한 구조적인 열화가속화 등 내구성 저하의 방지 차원에서 영향력이 큰 중요한 공정이다.The waterproofing of building structures is less than 1 ~ 3% of the total construction cost, which is insignificant in terms of money.However, not only the environmental aspects of maintaining a pleasant living environment for real residents, but also corrosion, neutralization, It is an important process that has a high impact in terms of preventing durability degradation such as structural deterioration acceleration due to freezing thawing and invasion of harmful substances.

건축물의 방수에 사용되는 비노출 방수공법은 노출방수공법 시공 단가의 약 50% 수준에서 시공이 가능한 공법으로서 국내 옥상방수공법의 70%를 점유하고 있다. 그러나 이러한 경제적 장점에도 불구하고 저렴한 단가로 인해 노출방수공법과는 달리 고성능의 방수 재료가 사용되고 있지 않은 것이 현실로, 재료의 92%이상이 아스팔트계 재질이 사용되고 있다. The non-exposed waterproof method, which is used for waterproofing the building, can be constructed at about 50% of the unit price of the exposed waterproof method and occupies 70% of the domestic rooftop waterproof method. However, in spite of these economic advantages, due to the low cost, the high performance waterproof material is not used unlike the exposure waterproof method. As a result, more than 92% of the material is asphalt-based material.

불과 수년전까지만 해도 비노출방수공법의 82%는 아스팔트 열공법, 개량아스팔트 토치공법, 개량 아스팔트 열공법 등이 주로 사용되면서 냄새로 인한 환경오염, 민원발생, 토치 및 열풍기 사용으로 인한 전문인력 요구, 열이 과도하게 전달되었을 때 재료의 손상 및 변형부착 또는 바탕면과의 부착력 약화 등을 야기하는 문제점이 발생됨에 따라, 최근에는 자착식 아스팔트 시트가 사용되고 있으며 도막재의 단점과 시트의 단점을 보완하기 위하여 아스팔트 도막재 또는 우레탄 도막재를 시트와 함께 사용하는 복합공법의 사용도 점차 증가하고 있다.Until just a few years ago, 82% of non-exposure and waterproof methods mainly used asphalt thermal method, improved asphalt torch method, and improved asphalt thermal method, resulting in environmental pollution due to odor, civil complaints, demand for professional manpower due to the use of torch and hot air fan, and heat. As such problems cause problems such as damage and deformation of the material or weakening of adhesion to the base surface when excessively transmitted, self-adhesive asphalt sheets are used in recent years. The use of the composite method which uses a coating material or a urethane coating material with a sheet is also gradually increasing.

그러나 자착식 아스팔트 시트의 경우, 시트 후면에 자체 점착성을 부여하여 바탕 콘크리트에 부착하는 방식을 사용함에 따라 접착력이 기존 열을 이용한 아스팔트 공법에 비해 낮고, 바탕면의 상태 즉 레이턴스의 처리상태, 바탕면의 요철, 습윤상태 등에 따라 접착성능의 변동폭이 크다는 문제점을 보이고 있을 뿐만 아니라, 시트 이음부 방식을 겹침이음으로 처리함에 따라 바탕체의 열적 거동으로 인해 시트접합부가 쉽게 파단됨과 동시에 겹침이음 부위가 바탕체와 접착이 되지 않아 시트파단에 따른 누수발생시 물길을 형성하게 됨에 따라 방수성능을 상실하게 되는 등의 문제점이 발생되고 있다. However, in the case of self-adhesive asphalt sheets, the adhesive strength is lower than that of the asphalt method using heat by applying the self-adhesive property to the back of the sheet and attaching it to the ground concrete. Not only does it show a problem that the variation in adhesion performance is large depending on the surface irregularities and wet conditions, and the sheet joints are easily broken due to the thermal behavior of the substrate as the sheet joints are treated as overlapping joints. There is a problem such as the loss of waterproof performance as the water is formed when the leak occurs due to sheet breakage due to the adhesive does not adhere.

또한 도막재와 개질아스팔트시트를 이용한 대표적인 비노출복합공법으로는 문헌 1의 등록특허 제10-0638990에 개시된 우레탄과 양면부직포 형태의 대흥산업 하이브리드 냉공법과 문헌 2의 공개특허 제2000-0002469호에 개시된 상용성을 높이도록 아스팔트계의 도막재와 개질아스팔트 시트의 하층부에 부직포를 부착하고 상층부 PE필름을 부착하며 양면에 아스팔트 컴파운드가 도포된 합성수지재가 개재되어 있는 한본 인더스트리의 매스틱 도막 시트 이중방수 공법이 있으나 하이브리드 냉공법의 경우 절연공법으로 하자 발생시 유지보수 관리에 어려움이 있으며, 작업자의 미숙으로 인한 교반불량 등으로 우레탄의 용제가 아스팔트 시트를 용해시켜 방수층의 손상을 가져와 방수의 문제점을 야기시킨다.In addition, typical non-exposure composite methods using a coating material and modified asphalt sheet are disclosed in Daeheung Industrial Hybrid Cold Forming Method in the form of urethane and double-sided nonwoven fabric disclosed in Patent Document 10-0638990 of Document 1 and Publication No. 2000-0002469 in Document 2 In order to increase the compatibility, Hanbon Industries' mastic coating sheet double waterproofing method is applied with nonwoven fabric attached to the lower layer of asphalt-based coating material and modified asphalt sheet, PE film attached to the upper layer, and synthetic resin material coated with asphalt compound on both sides. However, in the case of hybrid cold method, the insulation method is difficult to maintain and maintain when defect occurs. Urethane solvent dissolves the asphalt sheet due to poor agitation due to inexperienced workers, causing damage to the waterproof layer, causing problems of waterproofing.

또한 매스틱 방수의 경우에는 용제형의 아스팔트 컴파운드가 기존 우레탄 같은 액상에 비해 점도가 많이 높아 도포작업이 힘들어 작업의 효율이 떨어지며 Gel 상태의 아스팔트 컴파운드가 굳는 현상이 발생되어 콘크리트의 균열에 대한 추종성을 지속적으로 기대하기는 어려우며 조인트 연결부위 역시 바닥 도포용의 용제형 아스팔트 컴파운드를 사용하고 있어 이질재료로 수밀한 복합화 형성이 어려우며 용제형의 아스팔트 컴파운드라 결국 용제가 휘발되어 일정 시간이 경과하게 되면 딱딱하게 굳어져 도막재의 탄성과 인장강도 등이 미약하게 되어 이음부 파단 위험성이 존재한다. In the case of mastic waterproofing, solvent-type asphalt compound has a higher viscosity than conventional liquid such as urethane, so it is difficult to apply the coating work and the work efficiency decreases. As a result, the asphalt compound in the gel state is hardened. It is difficult to expect continuously, and joint joints also use solvent-based asphalt compound for floor coating, which makes it difficult to form a complex complex with dissimilar materials. Solvent-type asphalt compound eventually evaporates the solvent and hardens after a certain period of time. There is a risk of joint breakage due to weakened elasticity and tensile strength of the coating material.

따라서 이러한 자착식 시트와 복합공법의 문제점을 보완하고 자재를 정량시공하면서, 미숙련자도 쉽게 시공할 수 있고, 다양한 콘크리트 구조물(PC, RC, 하프PC 등)과 기후 변화, 현장 여건이나 시공자의 선호도에 따라 선택적으로 적용될 수 있으면서, 탁월한 방수성능을 발휘하도록 하는 도막재 개발과 이를 이용한 복합방수공법의 개발이 매우 중요하다.Therefore, the problem of self-adhesive sheet and composite method can be compensated and the material can be quantitatively constructed, and the unskilled person can be easily installed, and it can be applied to various concrete structures (PC, RC, Half PC, etc.) According to the present invention, it is important to develop a coating material and a composite waterproofing method using the same, which can be selectively applied and exhibit excellent waterproofing performance.

본 발명의 목적은 비노출 방수자재로서 탄성과 신장율이 우수하며 하절기의 고온과 아스팔트의 점도가 상승되는 동절기 저온에서도 시공상의 간편성과 경제성을 갖춘 비노출 복합방수공법으로 별도의 프라이머 도포 작업없이 시공 가능한 도막재 즉 1액형의 연질 고무아스팔트계 도막재로서 칙소성이 부여되면서 시공성이 양호하고 작업자들이 선호하는 우레탄 수준의 점도(6000~14000cPs)로 점도가 낮고 무기질 재료 특히 콘크리트와의 접착력이 우수하여 별도의 프라이머 작업 공정이 필요없으며, 작업성 또한 우수하여 롤라 및 레끼 작업이 가능하며, 1액형 제품으로 빠른 시간내 반고체화되어 후속작업이 용이하며, 현장에서 점도 조절을 하여 사용할 수도 있으며, 칙소성이 부여되어 아스팔트의 문제점인 내열 흐름 저항성을 향상시켰으며 일정 시간이 경과 후에도 Gel상 보다는 점도가 높고 고체상보다는 점도가 낮은 반고체상의 연질 고무아스팔트계로서 점도 유지성이 있어 탄성력과 신장율을 극대화한 도막재를 제공하는 것이다. An object of the present invention is an unexposed waterproofing material, which has excellent elasticity and elongation rate, and is a non-exposed composite waterproofing method with simplicity and economy in construction even at low temperature in winter when the high temperature in summer and the viscosity of asphalt are increased, and can be applied without additional primer coating work. In other words, it is a one-component soft rubber asphalt coating film material, which is provided with thixotropy and has good workability, and has a high viscosity (6000 ~ 14000 cPs) of the urethane level preferred by workers, and has a low viscosity and excellent adhesion to inorganic materials, especially concrete. No work process is required and workability is also excellent, so it is possible to work with rollers and squirts. It is a one-component product that semi-solidizes in a short time for easy follow-up work, and can be used by adjusting the viscosity in the field. Improved heat flow resistance, which is a problem of asphalt, As soft rubber asphalt on the high viscosity has a viscosity lower than the solid phase rather than the Gel-based semi-solid even after lapse of the retention's viscosity is to provide a coating material which maximizes elasticity and elongation.

나아가 바닥도포용 보다 더 빠른 건조와 칙소성을 부여한 벽체 도포용을 함께 개발하여, 종래에 우레탄실란트를 벽체 도포용으로 많이 사용함으로써 우레탄과 아스팔트 재료의 상응성이 없어 바닥과 벽체의 연결부위에서 빈번한 누수가 발생하는 문제점을 해결하고자 하는 것이다.Furthermore, by developing a wall coating that gives faster drying and thixotropy than floor coating, and by using urethane sealant for wall coating, there is no correspondence between urethane and asphalt material, so it frequently leaks at the connection between floor and wall. Is to solve the problem that occurs.

따라서 본 발명의 목적은 비노출복합공법의 문제점인 조인트 부위 및 코너부위의 이음매들에 대한 하자요인을 줄일 수 있는 도막재를 제공하는 것이다.Accordingly, an object of the present invention is to provide a coating material that can reduce the defects on the joints and corners of the joint which is a problem of the non-exposure composite method.

또한 종래의 용제형 및 수성 고무아스팔트계 도막재 제조방법은 제1단계와 2단계 각각을 배치(batch)별로 제조 후 1단계와 2단계를 혼합하는 제조방식으로 제조함으로써, 제조시간도 길며 제조방법도 복잡하였으나 본 발명은 보다 간편한 제조방법 즉 순차적으로 1 배치(batch)에 원료를 투입하여 제조하는 방식으로 개선하여 제조효율성을 높인 제조방법을 제공하는 것이다.In addition, the conventional solvent-type and water-based rubber asphalt coating material manufacturing method is prepared by mixing the first step and the second step after each step (batch) by the manufacturing method of mixing the first step and the second step, the manufacturing time is long and the manufacturing method Although it is complicated, the present invention provides a manufacturing method that improves manufacturing efficiency by improving the manufacturing method by a simpler manufacturing method, that is, by sequentially inputting the raw materials into one batch.

나아가 현장 여건이나, 작업자의 선호도에 따라 선택적으로 다양하게 형성될 수 있는 연질 고무아스팔트도막재를 이용한 선택형 비노출 복합방수구조를 제공하기 위한 것이다.Furthermore, it is to provide a selective non-exposed composite waterproof structure using a soft rubber asphalt coating material which can be formed in various ways depending on site conditions or worker preferences.

본 발명에 따른 연질 고무아스팔트계 도막재는 1액형으로 2가지 타입으로 형성될 수 있는 데, 즉 바닥도포용과 벽체도포용으로 구분 형성될 수 있으며 바닥도포용은 탄성력 및 신장율 극대화 하면서 점도를 낮춰 작업성을 더욱 용이하게 하였으며 벽체도포용은 바닥도포용에 건조를 더 빠르게 하여 후속 공정을 할 수 있도록 하였으며 또한 칙소성을 더 부여 하여 벽체시공이 가능한 도막재이다. The soft rubber asphalt coating material according to the present invention can be formed into two types in one component type, that is, it can be divided into floor coating and wall coating. The wall coating is easier to dry, and the floor coating is faster to dry the floor coating, so that the subsequent process can be performed.

제 1 타입으로 형성되는 연질 고무아스팔트계 도막재는 바닥 도포용으로서, 스트레이트 아스팔트 25~35 wt%, 수소첨가개질유(Hydro treated lube base oil) 3~7 wt%, 속건성석유용제(Aliphatic hydrocarbon계) 5~15 wt%, 칙소성보강재(탈크,해포석,실리카 중 어느하나) 2~5 wt%, EVA Emulsion 0.5~1 wt%, 수용성고분자가교제(SB라텍스, 부틸라텍스, 아크릴 라텍스 중 어느하나) 5~10 wt%, 탄산칼슘(중탄) 25~35 wt%, 시멘트 3~7 wt%, 침강방지제(폴리아마이드계, 폴리올레핀계 중 어느하나) 1~2 wt%로 구성되며, The soft rubber asphalt coating material formed of the first type is used for floor coating, straight asphalt 25-35 wt%, hydrogen treated lube base oil 3-7 wt%, quick-drying petroleum solvent (Aliphatic hydrocarbon type) 5 ~ 15 wt%, thixotropic reinforcements (either talc, disintegrated stone, silica) 2 ~ 5 wt%, EVA Emulsion 0.5 ~ 1 wt%, water-soluble polymer crosslinker (any of SB latex, butyl latex, acrylic latex) 5 ~ 10 wt%, calcium carbonate (heavy carbon) 25-35 wt%, cement 3-7 wt%, sedimentation inhibitor (either polyamide-based or polyolefin-based) 1-2 wt%,

수소첨가개질유(Hydro treated lube base oil), 속건성석유용제(Aliphatic hydrocarbon계), EVA Emulsion, 탄산칼슘(중탄), 칙소성보강재 Hydro treated lube base oil, Fast drying petroleum solvent (Aliphatic hydrocarbon type), EVA Emulsion, Calcium carbonate (heavy charcoal), Thixotropic reinforcement

(탈크,해포석,실리카 중 어느하나)를 혼합 분산 시킨 후 스트레이트아스팔트를 소량씩 투입하면서 분산 시키고, 여기에 수용성고분자가교제(SB라텍스, 부틸라텍스, 아크릴 라텍스 중 어느하나)를 투입하여 1시간이상 교반 가교결합 시키면서 시멘트와 침강방지제를 투입하여 제조한다.After mixing and dispersing (any one of talc, disintegrated stone and silica), add a small amount of straight asphalt and disperse it, add water-soluble polymer crosslinker (any one of SB latex, butyl latex, and acrylic latex) and stir for at least 1 hour. It is prepared by adding cement and sedimentation inhibitor while crosslinking.

탄산칼슘은 입자 크기가 중탄인 10~20㎛ 사용하는 것이 좋으며, 수소첨가개질유(Hydro treated lube base oil)는 온도에 안정한 인화점이 180℃이상, 저온에서의 흐름성이 좋은 유동점 -20℃ 이하의 것을 사용하는 것이 바람직하며, 이 수소첨가개질유의 투입과 수용성 고분자 가교결합으로 아스팔트가 점?접착성을 가지며 유동성이 좋아져 바닥 모체와의 거동 대응성 및 접착력을 유지하여 완벽한 방수를 구성하게 된다.Calcium carbonate is recommended to use 10 ~ 20㎛ particle size of heavy carbon, Hydro-treated lube base oil has a flash point stable at temperature above 180 ℃, flow point at low temperature -20 ℃ below It is preferable to use it. As a result of the addition of the hydrogenated reforming oil and the water-soluble polymer crosslinking, the asphalt has a viscosity and adhesiveness, and the fluidity is improved, thereby maintaining the behavior correspondence and adhesion with the bottom matrix to form a perfect waterproof.

또한 동절기 시공 및 원활한 작업성을 확보하기 위해 수소첨가개질유(Hydro treated lube base oil)와 속건성석유용제(Aliphatic hydrocarbon계)를 투입하였으며, 부착력이 좋은 EVA Emulsion투입하여 접착력을 높였다.In addition, in order to secure the construction and smooth workability during winter season, hydrogen treated lube base oil and fast-drying petroleum solvent (Aliphatic hydrocarbon-based) were added.

수용성고분자가교제(SB라텍스, 부틸라텍스, 아크릴 라텍스 중 어느하나)를 투입하여 가교 결합으로 자체 기계적 강도를 높이고 비중이 높은 시멘트를 투입 함으로써 기계적강도를 더 보완 하고 제조시 도료 분산력도 높였으며 칙소성보강재(탈크,해포석,실리카 중 어느하나)를 투입하여 칙소성과 높여 시공 후 내부 온도가 50℃이상에서도 흘러 내림성을 보완 하였으며 시공시 EVA Emulsion과 칙소성보강재가 바닥 표면의 습기가 존재하더라도 습기를 흡수하여 부착성을 더욱 향상시켰다.By adding water-soluble high molecular weight crosslinking agent (any one of SB latex, butyl latex, or acrylic latex), the mechanical strength is increased by crosslinking, and cement is added with high specific gravity to supplement the mechanical strength. (Talk, Haeposeok, and Silica) is added to increase the thixotropy and increase the flow resistance even after the internal temperature is over 50 ℃ .In case of construction, the EVA Emulsion and the thixotropic reinforcement retain moisture even when there is moisture on the floor surface. Absorption to further improve adhesion.

온도에 대한 영향을 최소로 하기 위하여 온도에 민감한 원료인 아스팔트 함량을 줄였으며 수소첨가개질유(Hydro treated lube base oil) ? 속건성석유용제(Aliphatic hydrocarbon계)를 첨가하여 겨울철과 같이 기온이 영하로 되는 조건에서도 작업성을 확보 및 콘크리트 바닥으로 침투하여 접착제 및 프라이머를 도포하지 않더라도 충분한 접착력을 부여 하였으며, 아스팔트와 수용성고분자가교제의 가교결합으로 Gel화를 유지시켜 겨울철의 작업성 및 점?접착력을 지속적으로 유지하여 방수능력을 향상시켰다.In order to minimize the effect on temperature, the content of asphalt, a temperature-sensitive raw material, was reduced and Hydro treated lube base oil? By adding fast-drying petroleum solvent (Aliphatic hydrocarbon type), it secures workability even under the condition of freezing temperature like winter season and penetrates concrete floor and gives sufficient adhesion even without applying adhesive and primer. By maintaining the gelation by cross-linking, it maintains the workability and adhesiveness of the winter season and improves the waterproof ability.

또한 종종 모체 크랙 부위로 아스팔트 흘러내려 주차장 바닥에 떨어져 문제시 되었으나 칙소성보강재(탈크,해포석,실리카 중 어느하나) 투입으로 칙소성이 부여되어 모체의 크랙에 대해서도 유동성은 확보되면서 흘러 내림성은 보완될 수 있도록 하였다.In addition, the asphalt flows to the mother cracks and often falls to the floor of the parking lot, which is a problem. To make it possible.

제2 타입의 연질 고무아스팔트계 도막재는 벽체도포용으로서, 상기한 제1 타입의 바닥도포용에 수소첨가개질유, 속건성석유용제, 칙소성보강재의 투입함량이 조절되어 칙소성을 더 부여하여 상온 흐름성을 줄인 제품으로 제조될 수 있으며 바닥도포용과 동일한 제조방법이나 초기 유성분산제를 수소첨가개질유(Hydro treated lube base oil), 속건성석유용제(Aliphatic hydrocarbon계) 투입 시 같이 투입하는데, 이는 칙소성이 높아진 도료의 제조 시 균일한 분산을 위해 미리 투입 되어 제조되는 것이며, 분산제로는 도료의 점도를 낮추면서 분산력이 좋은 유성분산제(고분자량의 불포화 폴리카보닉산계) 사용하는 것이 바람직하다.The soft rubber asphalt coating material of the second type is for wall coating, and the content of hydrogenated reforming oil, quick-drying petroleum solvent, and thixotropic reinforcement is adjusted to room temperature by adding the hydrogenated reforming oil, the quick-drying petroleum solvent and the thixotropic reinforcement to the floor coating of the first type. It can be manufactured as a product with reduced flow, and the same manufacturing method or initial oil powder as for floor coating is added when adding hydro treated lube base oil or quick-drying petroleum solvent. In the manufacture of paints having high sintering, they are prepared in advance for uniform dispersion, and as a dispersant, it is preferable to use an oil-based acidic agent (high molecular weight unsaturated polycarboxylic acid system) having good dispersibility while lowering the viscosity of the paint.

제2 타입의 연질 고무아스팔트계 도막재는 스트레이트 아스팔트 25~35 wt%, 수소첨가개질유(Hydro treated lube base oil) 3~5 wt%, 속건성석유용제(Aliphatic hydrocarbon계) 3~10 wt%, 유성분산제(고분자량의 불포화 폴리카보닉산계) 0.2~0.5 wt%, 칙소성보강재(탈크,해포석,실리카 중 어느하나) 5~10 wt%, EVA Emulsion 0.5~1 wt%, 수용성고분자가교제(SB라텍스, 부틸라텍스, 아크릴 라텍스 중 어느하나) 5~10 wt%, 탄산칼슘(중탄) 25~35 wt%, 시멘트 3~7 wt%, 침강방지제( 폴리아마이드계, 폴리올레핀계 중 어느하나) 1~2 wt% 를 투입하여 제조된다.

제1 및 제2 타입의 연질 고무아스팔트 도막재는 KSF 3211의 고무 아스팔트계 시험방법으로 측정시 신장율은 800%이상시 파단되지 않으며 칙소성보강재 ? 수용성고분자가교제(SB라텍스, 부틸라텍스, 아크릴 라텍스 중 어느하나)의 투입으로 칙소성이 증가하여 벽체형 시공이 가능하도록 하였다. 또한 속건성 석유용제를 사용하여 건조시간을 빠르게 빠른 탄성력 신장율을 발위 하도록 하여 후속 작업이 바로 가능하게 한 제품 이며 저온에서의 작업성 향상을 위해 아스팔트의 함량을 줄여 투입하고 수소첨가개질유(Hydro treated lube base oil)를 투입함으로써 겨울철의 기온이 영하 이하로 되더라도 작업성을 향상시켰으며 희석재를 첨가 교반하여 현장 여건에 따라 희석하여 사용할 수 있도록 배합을 설계하였다The soft rubber asphalt coating material of the first and second type is the rubber asphalt test method of KSF 3211. By adding water-soluble polymer crosslinking agent (any one of SB latex, butyl latex, acrylic latex), the thixotropy was increased to enable wall-type construction. In addition, by using fast-drying petroleum solvent, it is possible to follow up work immediately by developing fast elastic elongation rate and drying time. Reduced content of asphalt to improve workability at low temperature and add hydrogen treated lube. By adding base oil, the workability was improved even when the temperature in winter was below freezing and the mixture was designed to be diluted according to the site conditions by adding and stirring the diluent.

희석재로는 지방족 탄화수소계 및 방향족 탄화수소계 모두 사용가능하나 아스팔트와 상용성이 더 좋은 지방족 탄화수소계가 바람직하다.
As the diluent, both aliphatic hydrocarbons and aromatic hydrocarbons can be used, but aliphatic hydrocarbons having better compatibility with asphalt are preferable.

The soft rubber asphalt coating material of the first type or the second type basically has cold resistance which does not break even at minus 30 ° C., and its basic physical properties are excellent in elongation and elastic restoring force, especially in the first type, namely, soft rubber asphalt for floor coating. In the case of a system coating material, it has the characteristic of excellent adhesive force even in wet conditions.

본 발명에 따르면, 연질 고무아스팔트계 도막재를 사용함으로써 후속작업이 곧바로 진행될 수 있을 뿐만 아니라, 시공 현장의 여건이나 기후조건 또는 시공자의 선호에 따라 낮은 점도의 작업성위주의 제1 타입, 즉 바닥도포용 또는 건조가 빠르면서 칙소성이 부여된 제2 타입, 즉 벽체도포용을 취사 선택하여 이용할 수 있는 이점이 있다.According to the present invention, not only can the follow-up work proceed immediately by using the soft rubber asphalt coating material, but also the first type of workability-oriented floor having low viscosity depending on the conditions of the construction site, climatic conditions, or the preference of the installer. There is an advantage in that it is possible to select and use the second type, that is, wall coating, for which application or drying is fast and to which the thixotropy is imparted.

도 2는 본 발명의 일 실시예에 따라 방수시트를 겹침이음으로 시공하는 방법을 개략적으로 도시한 도면이다. 도시된 바와 같이 제1 방수시트(200)는 제1 연질 고무아스팔트계 도막재(100) 상부에 포설될 때 다른 제1 방수시트(200)와 겹침구간(a)을 갖도록 포설된다. 제1 방수시트(200)의 상부로 제2 연질 고무아스팔트계 도막재(300)를 개재하여 포설되는 제2 방수시트(400)의 경우에도 역시 다른 제2 방수시트(400)와 겹침구간(a)을 갖도록 시공된다. 이는 방수시트간 조인트 부분은 취약하여 시공 중 또는 시공 후 파단우려가 있으므로, 충분한 겹침이음으로 이를 보강하기 위한 것이다. 겹침구간은 약 50mm이상인 것이 바람직하다. 2 is a view schematically showing a method for constructing a waterproof sheet with overlapping joints according to an embodiment of the present invention. As shown, the first waterproof sheet 200 is installed to have an overlapping section a with the other first waterproof sheet 200 when the first waterproof sheet 200 is installed on the first soft rubber asphalt coating layer 100. In the case of the second waterproof sheet 400 installed through the second soft rubber asphalt-based coating material 300 to the upper portion of the first waterproof sheet 200, the overlapping section with the other second waterproof sheet 400 is also (a It is constructed to have). This is because the joint part between the waterproof sheets is fragile and there is a risk of breakage during or after construction, so as to reinforce it with sufficient overlapping joints. The overlapping section is preferably about 50 mm or more.

제2 방수시트(400)의 포설시에는 "+"와 같이 제1 방수시트(200)의 포설방향과 교차되는 방향으로 제2 방수시트(400)를 포설하는 것이 견고한 방수구조 달성에 유리하다.When installing the second waterproof sheet 400, it is advantageous to achieve a robust waterproof structure by installing the second waterproof sheet 400 in a direction crossing the installation direction of the first waterproof sheet 200, such as "+".

도 3은 방근성능이 요구되는 현장에 적용될 수 있는 방수구조를 도시한 도면이다.3 is a view showing a waterproof structure that can be applied to the site that requires the performance of the weather.

먼저 제1 연질 고무아스팔트계 도막재(100), 제1 방수시트(200), 제2 연질 고무아스팔트계 도막재(300) 및 제2 방수시트(400)로 형성되는 상기한 도 1의 방수구조 위에 PET 필름시트(500)가 맞댄이음으로 시공되되, 조인트에는 뿌리억지제(P)가 도포된 후 조인트를 포함하는 부위가 접착필름(600)에 의하여 추가적으로 커버된다. 접착필름(600)은 상부에 우레탄과 특수 고분자의 결합으로 이루어진 고탄성 필름이 형성되고 저면으로 아크릴계 점착제를 도포하여 형성한 것으로 사이에 뿌리억지제(P)가 도포된 PET 필름시트(500)간을 연결 마감하기 위해 형성된다. 따라서 조인트 부위에 요구되는 방근성능이 완벽하게 확보될 수 있게 된다.First, the waterproof structure of FIG. 1 is formed of the first soft rubber asphalt coating material 100, the first waterproof sheet 200, the second soft rubber asphalt coating material 300 and the second waterproof sheet 400. The PET film sheet 500 is constructed as a butt joint, but the joint is additionally covered by the adhesive film 600 after the root inhibitor P is applied to the joint. The adhesive film 600 is formed by applying an acrylic pressure-sensitive adhesive on the bottom and a high elastic film formed of a combination of a urethane and a special polymer on the upper portion of the PET film sheet 500 coated with a root inhibitor (P) therebetween. The connection is formed to finish. Therefore, the rooting performance required at the joint part can be secured perfectly.

상부에 상기한 PET 필름시트(500)가 사용되면, 인장강도, 내충격성, 내뚫림성, 내한성 등의 물리적 성능이 향상될 뿐만 아니라 도막재와 부착성능이 우수하고 방수구조에 대한 충분한 보호를 제공할 수 있을 뿐만 아니라 후속공정의 신속한 진행도 가능한 이점이 있다.When the PET film sheet 500 is used on the top, not only the physical performance of tensile strength, impact resistance, puncture resistance, cold resistance, etc. is improved, but also excellent adhesion to the coating material and provide sufficient protection for the waterproof structure. Not only that, but also the rapid progress of subsequent processes has the advantage.

따라서 본 발명에 따르면, 도막재로서 연질 고무아스팔트계 도막재가 사용됨으로써 경화시간을 기다려 후속공정을 진행할 필요없이 후속공정이 곧바로 진행될 수 있을 뿐만 아니라, 도막재와 방수시트를 적층적으로 시공함으로써 견고한 방수구조가 형성될 수 있다.Therefore, according to the present invention, since the soft rubber asphalt-based coating material is used as the coating material, the subsequent process can be immediately proceeded without having to wait for the curing time and proceed with the subsequent process, as well as providing a solid waterproof by laminating the coating material and the waterproof sheet. A structure can be formed.
