Abstract
Description
최근 몇 년 사이에 시트방수공법과 도막방수공법을 결합하여 일방 공법의 장점으로 타방 공법의 단점을 보완하여 신뢰성 높은 방수층을 제공하고자 하는 목적으로 복합방수공법의 개발이 이루어지고 있으며 현장적용도 점차 활발해지고 있다.In recent years, the composite waterproof method has been developed for the purpose of providing a reliable waterproof layer by combining the sheet waterproof method and the film waterproof method to compensate for the disadvantages of the other method with the advantages of the one-way method. Is getting.
시트방수공법에 사용되는 합성 고분자계 방수용 시트(KS F 4911 참조)는 신장률이 크기 때문에 건축물 모체의 균열 또는 거동에 대한 추종성·순응성이 양호하고, 일반적으로 내후성·내수성·내열성 등 충분한 내구성을 가지고 있어 외국에서는 오래전부터 많이 사용되어 왔고 국내에도 간혹 적용되고 있으나, 일반 건축물의 노출형 방수에 사용하는 경우 특히 시트간의 이음부위에서의 방수사고가 여전히 문제시되고 있다.The synthetic polymer waterproof sheet (see KS F 4911) used in the sheet waterproofing method has a high elongation rate, and therefore has good followability and conformity to cracks or behavior of the building matrix, and generally has sufficient durability such as weather resistance, water resistance, and heat resistance. It has been used a lot in foreign countries for a long time and is sometimes applied in Korea. However, when it is used for exposed waterproofing of general buildings, waterproof accidents at joints between sheets are still a problem.
도막방수공법의 하나로 시멘트 혼입 폴리머계 도막방수재(KS F 4919 참조)를 이용한 도막방수공법은 콘크리트 바탕체의 습윤 상태에 크게 영향을 받지 않고 바탕체의 거동에 적응할 수 있는 신축성·내균열성 및 내구성·투습성·통기성을 가지고 있으며, 이음부위 없는 연속적인 방수층을 형성하고 복합한 형상의 구조물에서도 시공성이 뛰어난 장점을 보인다.Coating waterproofing method using cement-based polymer coating waterproofing material (see KS F 4919) is one of the coating waterproofing methods, which is not affected by the wet state of concrete substrates and can adapt to the behavior of the substrates. It has breathability, forms a continuous waterproof layer without joints, and shows excellent workability even in a compound structure.
그러나 일반적으로 도막방수공법은 목적하는 방수효과를 얻기 위해 여러 층으로 방수재를 도포하는데 보통 다음 층의 도포를 위해 보통 24 시간 정도의 경화시간을 기다려야 하므로 도포하는 횟수가 많을수록 대기시간에 따른 시공상의 비효율이 크게 발생하고, 신축성에 비해 균열저항성이 떨어지는 단점을 안고 있다.In general, however, the coating waterproofing method applies waterproofing materials in several layers to achieve a desired waterproofing effect. Usually, a curing time of about 24 hours is usually required for application of the next layer. This occurs largely, and has the disadvantage of inferior crack resistance compared to elasticity.
복합방수공법은 이상과 같은 시트방수공법과 도막방수공법을 결합하여 단일 층의 방수용 시트 위에 1 회 내지 2 회 도막방수재를 도포함으로써, 일방 공법의장점으로 타방 공법의 단점을 보완할 수 있어 매우 신뢰성 높은 방수층을 얻을 수 있는 공법으로 부각되고 있다.The composite waterproof method combines the sheet waterproof method and the film waterproof method as described above to apply the film waterproofing material once or twice on a single layer of waterproof sheet, so that the disadvantages of the other method can be compensated for the advantages of the one-way method, which is very reliable. It is emerging as a method to obtain a high waterproof layer.
그런데 지금까지 개발된 복합방수공법은 방수용 시트와 도막방수재의 접착력을 높이기 위해 방수용 시트의 본체에 부직포를 융착 또는 부착한 복합 시트를 주로 사용하고 있다.However, the composite waterproofing method developed so far uses mainly a composite sheet in which the nonwoven fabric is fused or adhered to the body of the waterproof sheet to increase the adhesion between the waterproof sheet and the coating waterproof material.
예를 들어, 「복합방수구조 및 그 시공방법」(특허등록번호 제 0238994호)에서는 "아스팔트시이트의 상면에 부직포의 모근이 심겨진 상태로 융착되고 그 모간은 외부로 돌출되므로 아스팔트시이트 상면에 도포되는 액상의 폴리우레탄이 모간 사이 사이로 깊이 침투되어 아스팔트시이트와 견고하게 접착"되게 하는 방법을 사용하고 있다.For example, in the "composite waterproof structure and its construction method" (Patent Registration No. 0238994), "the nonwoven fabric roots are fused on the upper surface of the asphalt sheet, and the hair shaft is protruded to the outside so that it is applied to the upper surface of the asphalt sheet. A liquid polyurethane is used to penetrate deeply between hair shafts and firmly adhere to the asphalt sheet.
이 공법이 현장에 실제로 적용하고 있는 방수시트는 아스팔트에 합성고무나 합성수지를 첨가하여 성질을 개량한 아스팔트를 단독으로 또는 폴리에스테르나 폴리프로필렌 등의 유기 합성섬유를 주원료로 하는 원지나 플라스틱필름을 적층시켜 만든 제품을 위와 같은 방법으로 개량하여 사용하고 있다.The waterproof sheet actually applied to the site is made of asphalt, which is made by adding synthetic rubber or synthetic resin to the asphalt alone, or laminated with raw materials or plastic films mainly composed of organic synthetic fibers such as polyester or polypropylene. The product made by making it is being used in the same way as above.
「콘크리트 구조물의 도막 및 시트 이중방수재」(특허등록번호 제 0278173호)에서는 "시트의 하부면 즉 아스팔트 매스틱 방수재와의 접착면에 폴리에스테르 장섬유 부직포가 부착되고, 이 장섬유 부직포가 콘크리트 모체의 표면에 도포된 아스팔트 매스틱 도막방수재를 함침시키므로써 접착력을 극대화"시키는 방법을 사용하고 있다.In "Coating and Sheet Double Waterproofing of Concrete Structure" (Patent No. 0278173), "A polyester long fiber nonwoven fabric is attached to the lower surface of a sheet, that is, an adhesive surface with an asphalt mastic waterproofing material, and this long fiber nonwoven fabric is a concrete matrix. Maximizing the adhesion by impregnating the asphalt mastic coating waterproofing material applied to the surface of the "".
특히 합성 고분자계 수지는 일반적으로 소수성(hydrophobicity)이 큰 물질로써 친수성(hydrophilicity)을 갖는 무기질계 도막방수재와는 그 접착성이 매우 부정적인 상관성을 보이기 때문에 주로 방수용 시트에 부직포 부착 또는 표면엠보싱처리 등을 통해 접착면적을 키우는 기계적 개선방법을 취하고 있다.In particular, synthetic polymer resins generally have high hydrophobicity and have a very negative correlation with the hydrophobic inorganic coating waterproof material. Therefore, non-woven fabrics or surface embossing treatments are mainly used for waterproof sheets. Through mechanical improvement method to increase the adhesion area through.
한 예로, 「2액형 무기질계 탄성 도막방수재, 이를 사용한 복합 도막 방수시트 및 이를 사용한 복합 도막 방수시공방법」(특허출원 제 1999-015798호)는 "기재의 상부에 도포되는 도막방수재와의 접착력을 향상시키기 위하여" 폴리에틸렌계 방수시트에 부직포를 열융착시키는 방법을 사용하고 있다.As an example, "A two-component inorganic elastic coating waterproofing material, a composite coating waterproofing sheet using the same, and a composite coating waterproofing method using the same" (Patent Application No. 1999-015798) describe "adhesion to a coating waterproofing material applied to the upper part of a substrate. In order to improve ", a nonwoven fabric is thermally fused to a polyethylene waterproof sheet.
그러나, 원하는 접착효과를 얻기 위해 방수용 시트에 부직포를 융착 또는 부착한 복합 시트는 시트의 제조공정이 복잡한 만큼 시트의 단가를 상승시켜 결과적으로 복합방수공법의 많은 장점에도 불구하고 시장성을 떨어뜨리는 요인으로 작용하며, 기게적인 방법을 이용한 복합 시트의 제조 및 시공 특성상 하자 발생의 가능성이 그만큼 높을 수밖에 없다.However, the composite sheet in which nonwoven fabric is fused or adhered to the waterproof sheet in order to obtain a desired adhesive effect increases the unit cost of the sheet as the manufacturing process of the sheet is complicated, and as a result, it is a factor that lowers the marketability despite the many advantages of the composite waterproofing method. In the manufacturing and construction characteristics of the composite sheet using mechanical methods, the possibility of defects is inevitably high.
본 발명의 복합방수공법에 사용하는 방수용 시트는 종래의 복합방수공법에서 시트와 도막방수재와의 접착력을 확보하기 위해 부착 또는 융착하는 부직포 층을 없애고, 폴리염화비닐수지에 아세트산비닐공중합체를 적정하게 배합하여 개질한 폴리염화비닐(PVC) 방수용 시트를 사용하여 아크릴산에스테르계 도막방수재와의 접착력을 강화하고 동시에 시트와 시트 간의 이음접합이 용이하게 하며, 방수용 시트의 물성을 확보하기 위한 배합공정에서 주요 재료로써 생활환경에서 대량으로 배출되고 있는 폐 폴리염화비닐수지를 사용함으로써 환경오염을 줄일 수 있을 뿐만 아니라 시공하고 남는 자체의 폐기물도 다시금 본 제품의 생산에 재활용이 가능한 장점을 제공코자 한다.The waterproof sheet used in the composite waterproofing method of the present invention eliminates the nonwoven fabric layer attached or fused to secure the adhesive force between the sheet and the coating waterproofing material in the conventional composite waterproofing method, and the vinyl acetate copolymer is appropriately applied to the polyvinyl chloride resin. The polyvinyl chloride (PVC) waterproof sheet, modified and blended, is used to enhance adhesion to acrylic ester coating waterproofing materials, and to facilitate jointing between sheets, and to secure the physical properties of the waterproof sheet. By using waste polyvinyl chloride resin which is discharged in large quantities from the living environment as a material, not only the environmental pollution can be reduced, but also the wastes left after construction will be reused in the production of this product.
또한 본 발명의 폴리염화비닐 방수용 시트(10)와 아크릴산에스테르계 도막방수재(20)를 사용한 복합방수공법을 통해 여타 복합방수공법보다 간편하고 신뢰성이 높은 방수층을 시공하는 방법을 제공하고자 한다.In addition, through the composite waterproof method using the polyvinyl chloride waterproof sheet 10 and the acrylic ester coating waterproofing material 20 of the present invention to provide a method for constructing a simple and reliable waterproof layer than other composite waterproof method.

발명자는 무엇보다 일반 건축물의 방수에 적용할 수 있는 고품질의 방수용 시트로써 거론되고 있음에도 불구하고 국내에서는 주로 토목공사의 차수용이나 수영장·폐기물처리장의 바닥차수용으로 그 사용이 제한되어 있는 폴리염화비닐(PVC) 방수용 시트를 주된 소재로 하여 시멘트 혼입 폴리머계 방수재 가운데 특히 아크릴산에스테르계 도막방수재(20) - 출원인인 극동크리트주식회사는 현재 아크릴산에스테르계 도막방수재로써 KS F 4919 기준에 적합한 크리트#3010 등의 제품을 생산 판매하고 있음 - 와 충분한 접착성을 가지게끔 개질된 방수용 시트를 발명하고자 하였다.Although the inventor has been mentioned as a high quality waterproof sheet that can be applied to the waterproofing of general buildings, polyvinyl chloride is limited in the domestic use mainly for the order of civil engineering work or the floor order of swimming pool and waste treatment plant. (PVC) Waterproofing sheet as the main material, especially among the cement-incorporated polymer waterproofing material, especially acrylic ester coating waterproofing material (20)-Applicant Kukdong Crete Co., Ltd. is currently an acrylic ester coating waterproofing material that meets KS F 4919 standard. To produce and sell the product-and to modify the waterproof sheet to have sufficient adhesion.
여러 가지 예비적인 시험 결과, 폴리염화비닐수지와 아세트산비닐공중합체를 적정한 범위의 비율로 배합함으로써, 아세트산비닐공중합체의 특유한 접착성을 이용하여 복합방수공법에 적용할 수 있는 충분한 접착력을 가진 방수용 시트를 생산할 수 있었다.As a result of various preliminary tests, a waterproof sheet having sufficient adhesion to be applied to the composite waterproof method using the unique adhesiveness of the vinyl acetate copolymer by blending polyvinyl chloride resin and vinyl acetate copolymer in an appropriate range ratio Could produce.
또한 발명의 또다른 한 축으로 상기의 방법으로 폴리염화비닐 방수용 시트(10)를 제작하는 방법으로 굳이 신재를 사용하지 않고 저렴한 가격에 대량으로 구입할 수 있는 폐재를 사용하는 방향으로 개발하였다.In addition, another axis of the invention has been developed in the direction of using a waste material that can be purchased in large quantities at a low price without using a new material by the method of producing a polyvinyl chloride waterproof sheet 10 by the above method.
이러한 과정을 통해 본 발명에 의한 폴리염화비닐 방수용 시트(10)는 폐 폴리염화비닐수지 70 내지 80 중량%, 폐 아세트산비닐공중합체 접착필름 스크랩을 재활용한 재생수지 14 내지 10 중량%, 폐 아세트산비닐공중합체 접착제를 재활용한 재생수지 8 내지 5 중량%, 석분 8 내지 5 중량%로 구성된다.Through this process, the polyvinyl chloride waterproof sheet 10 according to the present invention is 70 to 80% by weight of waste polyvinyl chloride resin, 14 to 10% by weight of recycled resin recycled waste vinyl acetate copolymer film scrap, and waste vinyl acetate It is composed of 8 to 5% by weight recycled resin recycled copolymer adhesive, 8 to 5% by weight stone powder.
이 배합에서 주 원료로 사용되는 폐 폴리염화비닐수지는 경질 또는 반경질 시트를 재활용한 재생수지이다. 석분은 일반적으로 사용되는 바와 같이 제조단가를 낮출 뿐 아니라 접착성에도 일정하게 기여하므로 소량을 첨가하였다.The waste polyvinyl chloride resin used as the main raw material in this formulation is a recycled resin obtained by recycling hard or semi-hard sheets. Stone powder was added to a small amount because it not only lowers the manufacturing cost as it is generally used but also contributes consistently to adhesion.
그리고 폴리염화비닐 방수용 시트(10)의 제품은 상기의 수지 및 석분을 상기의 범위 내에서 재생수지의 상태 및 소요 물성을 고려하여 적정한 비율로 배합하고 콤파운드로 만들어 이축압출기를 이용하여 뽑아낸다. 현장에 적용되는 폴리염화비닐 방수용 시트(10)는 일반적으로 폭 1 M, 두께 10∼20 MM, 길이 20 M의 롤 형으로 공장에서 생산된 제품을 사용한다.And the product of the polyvinyl chloride waterproof sheet 10 is blended in the appropriate ratio in consideration of the state and the required physical properties of the recycled resin within the above range and made into a compound and made out by using a twin screw extruder. Polyvinyl chloride waterproof sheet 10 is applied to the field is generally used in the factory produced products in the form of a roll width of 1 M, thickness 10-20 MM, length 20 M.
발명자는 본 발명이 목적하는 바와 같은 물성을 만족시킬 수 있는 폴리염화비닐 시트의 배합성분 및 배합비를 한정하기 위하여 다음과 같이 시험하였다.The inventors tested as follows in order to limit the blending components and blending ratio of the polyvinyl chloride sheet which can satisfy the physical properties as desired by the present invention.
폐 폴리염화비닐수지, 폐 초산비닐공중합체 접착 필름 스크랩을 재활용한 재생수지, 폐 초산비닐공중합체 접착제를 재활용한 재생수지 및 석분을 중량%를 달리하여 넣은 후 혼합하여 콤파운드로 만들어 이축 칼렌다 압출기를 사용하여 두께1.2 MM로 시트를 제조하여 각 방수용 시트의 물성을 측정한 결과를 다음 표에 나타내었다.Waste polyvinyl chloride resin, recycled resin recycled waste vinyl acetate copolymer adhesive film scrap, recycled resin recycled waste vinyl acetate copolymer adhesive and stone powder are mixed in different weight percent to make a compound to make a twin screw calender extruder. Using a sheet of 1.2 MM thick to measure the physical properties of each waterproof sheet is shown in the following table.
시험방법은 KS F 4911(합성 고분자계 방수 시트)에 명시되어있는 인장성능에 대해 상온, 60℃, -20℃에서의 인장강도와 신장율을 측정하였다.The test method measured tensile strength and elongation at room temperature, 60 ° C, and -20 ° C for the tensile performance specified in KS F 4911 (synthetic polymer waterproof sheet).

시험에서와 같이 폴리염화비닐수지 60 중량%에서는 인장강도 및 신장률이 상당히 많이 감소하는 것을 알 수 있으며 따라서 60 중량% 이하에서는 원하는 물성을 충족하지 못함을 알 수 있다. 이는 폴리염화비닐수지와 아세트산비닐공중합체간에 상용성이 어느 정도는 보장되나, 원재료인 폴리염화비닐수지에 아세트산비닐공중합체가 다량 들어갈 경우 상용성은 많이 감소하기 때문이다.As in the test, it can be seen that the tensile strength and the elongation rate are considerably reduced at 60% by weight of polyvinyl chloride resin, and therefore, it can be seen that the desired properties are not satisfied at 60% by weight or less. This is because the degree of compatibility between the polyvinyl chloride resin and the vinyl acetate copolymer is ensured to some extent, but when the vinyl acetate copolymer is contained in a large amount of polyvinyl chloride resin as a raw material, the compatibility is greatly reduced.
또한 폴리염화비닐수지 90 중량%에서는 인장강도와 신장률은 폴리염화비닐수지 70 또는 80 중량%일 때와 거의 비슷하게 나타났으나, 아크릴산에스테르계 도막방수재(20)인 크리트 #3010을 도포한 후 수행한 접합성능 시험에서는 별로 만족스럽지 않은 성능을 나타내었다. 이는 접착성을 갖게 하는 아세트산비닐공중합체의 함량이 줄고 폴리염화비닐수지의 함량이 증가할수록 접착성이 현저히 떨어지기 때문으로 파악된다.In addition, the tensile strength and the elongation of 90% by weight of polyvinyl chloride resin were almost the same as those of 70 or 80% by weight of polyvinyl chloride resin, but were applied after the application of Crete # 3010, an acrylic ester-based coating waterproofing material (20). Bonding performance test showed unsatisfactory performance. This is believed to be due to the fact that the adhesion decreases significantly as the content of the vinyl acetate copolymer which gives the adhesion decreases and the content of the polyvinyl chloride resin increases.
상기 폴리염화비닐수지 70 또는 80 중량%일 경우의 방수시트 위에 아크릴산에스테르계 도막방수재(20)인 「극동크리트 #3010」을 도포하여 접착력을 시험한 결과는 다음과 같으며, KS F 4917의 기준을 상회하는 접합성능을 나타내었다.The result of testing the adhesive strength by applying the "Far Copper Crete # 3010", which is an acrylic acid ester-based coating waterproofing material 20, on the waterproof sheet when the polyvinyl chloride resin is 70 or 80 wt% is as follows, and is based on KS F 4917. Bonding performance exceeding was shown.
시험방법은 KS F 4917에 명시되어있는 접합성능 시험방법을 간이하게 적용하였다. 참고로 KS F 4917에서 기준으로 하는 방수시트 간의 접합성능은 5.1 kgf/cm 이상이다.The test method simply applies the bonding performance test method specified in KS F 4917. For reference, the bonding performance between waterproof sheets based on KS F 4917 is more than 5.1 kgf / cm.
