이하, 첨부도면을 참조하여 본 발명의 실시예에 관하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1 이하에 도시된 바와 같이, 본 발명에 의한 복합방수공법은 기본적으로, 콘크리트(1) 표면에 프라이머를 도포하여 프라이머층(10)을 형성하는 단계; 부틸고무 혼합물에 의한 부틸고무 점착층(110)과, 부틸고무 점착층(110)의 상부에 장착된 박층 구조의 상부 보강재(120)로 구성된 부틸고무 방수시트(100)를 프라이머층(10)의 상부에 접착하는 단계; 부틸고무 방수시트(100)의 상부 보강재(120)의 상부에 폴리우레탄 도막방수재를 도포하여 도막방수층(20)을 형성하는 단계;를 포함하여 구성된다.As shown in Figure 1, the composite waterproof method according to the present invention basically, by applying a primer on the surface of the concrete (1) to form a primer layer (10); Butyl rubber waterproof sheet 100 composed of a butyl rubber adhesive layer 110 and a butyl rubber adhesive layer 110 of the thin layer structure mounted on top of the butyl rubber adhesive layer 110 by a butyl rubber mixture of the primer layer 10 Adhering to the top; And forming a waterproof coating layer 20 by applying a polyurethane coating waterproofing material on top of the upper reinforcing member 120 of the butyl rubber waterproof sheet 100.

즉, 종래의 복합방수공법에서 사용되던 아스팔트 방수시트 대신, 부틸고무 방수시트(100)를 적용한 것이다.That is, the butyl rubber waterproof sheet 100 is applied instead of the asphalt waterproof sheet used in the conventional composite waterproof method.

부틸고무 방수시트(100)의 부틸고무 점착층(110)을 형성하는 부틸고무 혼합물은, 폴리우레탄 도막방수재에 혼입된 우레탄 용제와 혼합되더라도 용해되지 않는 물성을 갖는다.The butyl rubber mixture forming the butyl rubber adhesive layer 110 of the butyl rubber waterproof sheet 100 has physical properties that do not dissolve even when mixed with the urethane solvent incorporated in the polyurethane coating waterproofing material.

따라서, 부틸고무 방수시트(100)의 시공 후, 폴리우레탄 도막방수재를 도포하더라도 방수시트의 점착층의 부착력을 유지할 수 있고, 가장자리의 들뜸현상을 방지할 수 있다는 효과가 있다.Therefore, even after applying the butyl rubber waterproof sheet 100, even if the polyurethane coating waterproofing material is applied, it is possible to maintain the adhesion of the adhesive layer of the waterproof sheet, it is possible to prevent the lifting of the edge.

이하, 부틸고무 방수시트(100)의 부틸고무 점착층(110)을 형성하는 부틸고무 혼합물의 구체적 구성에 대하여 설명한다.Hereinafter, a specific configuration of the butyl rubber mixture forming the butyl rubber adhesive layer 110 of the butyl rubber waterproof sheet 100 will be described.

부틸고무 혼합물은, 부틸고무 5~30중량%, 무기질 필러 10~60중량%, 점착부여제 15~45중량%, 개질재 2~15중량%, 안료 0.1~10중량%, 첨가제 0.1~5중량%를 포함하여 구성된다.The butyl rubber mixture is 5-30 wt% butyl rubber, 10-60 wt% inorganic filler, 15-45 wt% tackifier, 2-15 wt% modifier, 0.1-10 wt% pigment, 0.1-5 wt% additive It is composed of%.

부틸고무는 범용적으로 공장에서 생산되는 합성고무의 한 종류로서, 점접착성이 우수하고 내열내한성이 우수한 고무로서, 상기 부틸고무의 등급은 여러 가지가 있으나 본 발명에서는 그 등급을 제한하지 않는다. Butyl rubber is a kind of synthetic rubber produced at the factory in general, excellent adhesiveness and heat resistance excellent rubber, there are many grades of the butyl rubber, but the present invention does not limit the grade.

부틸성분이 5중량% 미만이 되면 그 사용량이 너무 적어 탄성 및 신장률 등의 물성이 저하되고 부틸고무 특유의 충진 특성이 충분히 발휘되지 않는 등의 문제가 있고, 30중량%을 초과하면, 그 사용량이 필요이상의 사용으로 가격경쟁력이 낮아진다.If the butyl component is less than 5% by weight, the amount of the butyl component is so small that the physical properties such as elasticity and elongation are deteriorated, and the filling property peculiar to butyl rubber is not sufficiently exhibited. More than necessary, price competitiveness is lowered.

무기질 필러는, 탄산칼슘, 탈크, 실리카, 마이카, 클레이, 플라이애쉬, 벤토나이트 중 하나 또는 2 이상의 혼합에 의해 형성된다.The inorganic filler is formed by mixing one or more of calcium carbonate, talc, silica, mica, clay, fly ash and bentonite.

무기질 필러거 10중량% 미만이 되면 제품의 압축강도가 저하되고, 60중량%를 초과하면 사용량이 너무 많아 제품의 탄성, 신장률, 점착강도 등의 물성을 저해하는 요인이 된다.When the inorganic filler is less than 10% by weight, the compressive strength of the product is lowered. When the inorganic filler is more than 60% by weight, the amount used is too much, which is a factor that impairs physical properties such as elasticity, elongation rate, and adhesive strength of the product.

점착부여제는, 석유수지, 폴리부텐, 로진(송진), 로진에스테르 중 하나 또는 2 이상의 혼합에 의해 형성된다.The tackifier is formed by mixing one or two or more of petroleum resin, polybutene, rosin (rosin), rosin ester.

석유수지는 C5계,C9계, 공중합수지, 수첨수지 등이 있으며 단독 또는 2종 이상 조합하여 사용할 수 있다. Petroleum resins include C5-based, C9-based, copolymerized resins, hydrogenated resins, etc. and may be used alone or in combination of two or more thereof.

폴리부텐은 등급이 여러 가지가 있으나 본 발명에서는 그 등급을 제한하지 않는다. Polybutene has many grades but the present invention does not limit the grades.

점착부여제가 15중량% 미만이 되면 점착제로서의 기능이 저하되고, 45중량%를 초과하면 필요 이상의 사용으로 가격경쟁력이 낮아진다.When the tackifier is less than 15% by weight, the function as an adhesive is lowered. When the tackifier is more than 45% by weight, the price competitiveness is lowered by using more than necessary.

개질제는, 천연고무(NR), 에스비에스고무(SBS), 클리로프렌고무(CR), 이피디엠고무(EPDM), 에스비알고무(SBR), 에틸렌비닐아세테이트(EVA), 아타티폴리프로필렌(APP), 비정형폴리올레핀(APAO), 폴리에틸렌(PE), 폴리프로필렌(PP) 중 하나 또는 2 이상의 혼합에 의해 형성된다.Modifiers are natural rubber (NR), SB rubber (SBS), chloroprene rubber (CR), EPDM rubber (EPDM), Esbial rubber (SBR), ethylene vinyl acetate (EVA), attapolypropylene (APP ), Amorphous polyolefin (APAO), polyethylene (PE), polypropylene (PP), or a mixture of two or more.

개질제가 2중량% 미만이 되면 사용량이 너무 적어 개질효과가 낮으며, 15중량%를 초과하면 사용량이 너무 많아 가격상승의 요인이 된다.If the modifier is less than 2% by weight, the amount of use is too low, so the effect of reforming is low.

안료는, 무기안료, 유기안료 또는 이들의 혼합에 의해 형성된다.The pigment is formed by an inorganic pigment, an organic pigment or a mixture thereof.

무기안료는, 카본블랙, 이산화티탄(백색), 적색 산화철, 황색 산화철, 산화철 중 하나 또는 2 이상의 혼합에 의해 형성된다.The inorganic pigment is formed by mixing one or two or more of carbon black, titanium dioxide (white), red iron oxide, yellow iron oxide, and iron oxide.

단, 납, 수은, 크롬 등의 중금속이 포함되어 제조된 안료는 사용하여서는 안 된다. However, pigments prepared by containing heavy metals such as lead, mercury and chromium should not be used.

그 사용량이 0.1중량% 미만이 되면 사용량이 너무 적어 원하는 색상의 제품을 기대하기 어렵고, 10중량%를 초과하면 과잉사용으로 가격경쟁력이 낮아진다.If the amount is less than 0.1% by weight, the amount is so small that it is difficult to expect a product of the desired color, and if it exceeds 10% by weight, the price competitiveness is lowered due to overuse.

첨가제로는 내열안정제, 자외선안정제, 광택제, 활제 등이 있으며 범용적으로 사용되는 자제이므로 그 종류를 제한하지는 않는다. 그 사용량은 0.1~5% 중량이 적정하다.Additives include heat stabilizers, ultraviolet stabilizers, brighteners, lubricants, etc., and are not used to limit the type of the additives. The amount of use thereof is appropriately 0.1 to 5% by weight.

이와 같은 구성을 취하는 부틸고무 혼합물은, 폴리우레탄 도막방수재에 혼입된 우레탄 용제와 혼합되더라도 용해되지 않는 물성을 갖는다.The butyl rubber mixture which has such a structure has the physical property which does not melt | dissolve even if mixed with the urethane solvent mixed in the polyurethane coating waterproofing material.

따라서, 부틸고무 방수시트(100)의 시공 후, 폴리우레탄 도막방수재를 도포하더라도 방수시트의 점착층의 부착력을 유지할 수 있고, 가장자리의 들뜸현상을 방지할 수 있다는 효과가 있다.Therefore, even after applying the butyl rubber waterproof sheet 100, even if the polyurethane coating waterproofing material is applied, it is possible to maintain the adhesion of the adhesive layer of the waterproof sheet, it is possible to prevent the lifting of the edge.

나아가, 이러한 부틸고무 혼합물은 점접착력이 우수함은 물론, 시공 편리성, 내구성 및 방수성능이 우수할 뿐만 아니라, 부착성능과 수밀성, 균열 충진성 등의 성능이 매우 우수하다. Furthermore, the butyl rubber mixture not only has excellent adhesive strength, but also has excellent construction convenience, durability, and waterproof performance, and also has excellent performance such as adhesion performance, water tightness, and crack filling properties.
