Abstract

The present invention provides a coating film waterproofing agent formed by mixing 25 to 60% by weight of a main agent formed by an inorganic filler and 40 to 75% by weight of a curing agent formed by a polymer emulsion. The curing agent includes 25 to 47% by weight of a liquid polymer, 2 to 5% by weight of a coupling agent, and 50 to 70% by weight of water. The liquid polymer is formed by one or a mixture of two or more of acrylic emulsion, EVA emulsion, water-dispersed urethane (PUD), water-dispersed acrylic urethane (AUD), and SBR latex. The coupling agent is formed by one or a mixture of two or more of epoxy-based, methacryloxy-based, and amino-based. With a composite application of a cement mixed polymer-based waterproofing material and an asphalt waterproofing sheet, since the waterproofing material penetrates a concrete matrix, even if cracks occur in concrete due to long-term micro-vibration, penetrating waterproofing molecules fill voids to realize semi-permanent waterproofing. Due to the elongation and tensile performance of a self-hardening cement-mixed polymer-based waterproofing material, it is possible to cope with microcracks in concrete.

Description

도막방수제 및 이를 이용한 복합방수공법{WATERPROOF AGENT AND COMPLEX WATERPROOF CONSTRUCTION METHOD}Coating waterproofing agent and composite waterproofing method using the same

본 발명은 건설 분야에 관한 것으로서, 상세하게는 도막방수제 및 이를 이용한 복합방수공법에 관한 것이다.The present invention relates to the field of construction, and more particularly, to a coating film waterproofing agent and a composite waterproofing method using the same.

각종 건물의 옥상, 외벽, 터널 및 지하실 등의 표면에는 방수 또는 방식 도막을 형성하는 것이 일반적이다.It is common to form a waterproof or anticorrosive coating film on the surfaces of roofs, exterior walls, tunnels, and basements of various buildings.

건축 기술 및 토목 기술의 발전으로 인하여 건물의 방수 기술도 종래의 시트(Sheet) 방수, 구체 방수, 도막 방수, 아스팔트 방수, 금속판 방수 및 개량 아스팔트 시트 방수 등 여러 종류의 방수 공법과 기술이 개발되었으나 공법에 따라서 각각의 특징과 시방의 문제점을 내포하고 있다.With the development of building technology and civil engineering technology, various types of waterproofing methods and technologies have been developed, such as conventional sheet waterproofing, sphere waterproofing, coating film waterproofing, asphalt waterproofing, metal plate waterproofing, and improved asphalt sheet waterproofing. Accordingly, each of the characteristics and specifications contains problems.

이러한 문제점으로는 시공 후의 효과의 차이점, 재시공 시의 인건비 문제, 시공 편의성, 자외선에 의한 노화 및 변질 문제, 흡수성 및 발수성 문제, 피착제와의 접착성 문제 등을 들 수 있으며, 최근에 와서는 시공상의 편의성 및 경제성이 건물 보수업계, 방수업계에서 문제로 부각되고 있다.These problems include differences in effects after construction, labor cost problems during re-construction, construction convenience, aging and deterioration problems caused by UV rays, water absorption and water repellency problems, and adhesion problems with adherends. The convenience and economic feasibility of the design is emerging as a problem in the building repair industry and the waterproofing industry.

일반적으로 기존의 복합방수는 우레탄 경화제로 인해 시트방수재가 녹는 현상 때문에 방수층이 충분히 형성되지 않아 콘크리트의 표면 외부로 흘러나옴으로써 환경 문제를 야기시키고, 이로 인해 미관상 좋지 않은 영향을 끼치고 있다.In general, conventional composite waterproofing causes environmental problems by flowing out of the surface of concrete because the waterproofing layer is not sufficiently formed due to the melting phenomenon of the sheet waterproofing material due to the urethane curing agent, which has an adverse effect on the aesthetics.

즉, 이와 같이 시트와 우레탄 혼합액이 콘크리트 외부로 흘러나오는 문제를 현재로서는 아직까지 해결하지 못하고 있는 실정이다.That is, the problem of the sheet and the urethane mixture flowing out of the concrete as described above has not been solved at present.

기존의 복합방수제들은 주로 절연 공법을 택하고 있는데, 이는 바탕면에서 전면부착이 아니고 일부분은 표면에서 떠있는 상태를 유지하는 방식이다.Existing composite waterproofing agents mainly use the insulation method, which is not attached to the entire surface of the base surface, but is a method to keep a part floating on the surface.

이는 콘크리트의 크랙이 발생하였을 경우 크랙에 의해 방수층이 밀려나지 않게 하기 위함이지만, 비노출 공법으로 시공함에 따라 방수시공 후 그 위에 흙을 되메우기 하면, 방수층이 흙에 밀려 버려 방수능력이 상실되는 문제점이 발생한다.This is to prevent the waterproofing layer from being pushed out by cracks in the case of cracks in the concrete, but as the non-exposed method is used, if the soil is backfilled after waterproofing, the waterproofing layer is pushed into the soil and the waterproofing ability is lost. do.

또한, 방수시공 후 무근콘크리트를 타설할 때, 방수층이 밀려나는 문제점도 발생하여 방수층이 형성되지 않아 하자가 일어난다.In addition, when pouring unsupported concrete after waterproofing, there is also a problem that the waterproofing layer is pushed out, which causes a defect because the waterproofing layer is not formed.

도막재와 아스팔트 시트를 적용하는 복합방수의 경우에는 열공법으로 인한 문제와(환경, 안전) 방수능력에서 한계를 보이고 있다.In the case of composite waterproofing using a coating material and asphalt sheet, problems due to the thermal method (environmental, safety) and waterproofing ability are limited.

상술한 문제점과 같이 기존의 복합방수 공법으로 시공되게 되면, 방수층이 콘크리트 표면에서 분리되어 표면에 떠있는 상태로 지속 되기 때문에 그 사이로 물이 스며들어 유입하게 되고, 이를 보수하기 위해 일부분이 아닌 전체 시공부위를 모두 들어내야 하는 문제점이 발생한다.As with the above problems, when the existing composite waterproofing method is used, the waterproofing layer is separated from the concrete surface and remains floating on the surface, so water seeps in and flows in between them. A problem arises in that all parts have to be lifted.

본 발명은 상기와 같은 문제점을 해결하기 위하여 도출된 것으로서, 시멘트 혼입 폴리머계 방수재와 아스팔트 방수시트를 복합으로 적용함으로써, 방수재가 콘크리트 모체에 침투하도록 하여 장기적인 미세진동에 의한 콘크리트의 균열이 발생하더라도 침투되어 있는 방수분자가 공극을 메움에 따라 반영구적인 방수를 실현할 수 있고, 자기경화형 시멘트 혼입 폴리머계 방수재의 신장율과 인장성능으로 인해 콘크리트의 미세균열에도 대응할 수 있도록 하는 도막방수제 및 이를 이용한 복합방수공법을 제시하는 것을 그 목적으로 한다.The present invention was derived to solve the above problems, and by applying a cement mixed polymer-based waterproofing material and an asphalt waterproofing sheet as a composite, the waterproofing material penetrates into the concrete matrix, so that even if cracks in concrete due to long-term micro-vibration occur, penetration The waterproofing molecule can realize semi-permanent waterproofing by filling the voids, and it is a coating film waterproofing agent that can respond to microcracks in concrete due to the elongation and tensile performance of the self-hardening cement mixed polymer waterproofing material and a composite waterproofing method using the same. The purpose is to present it.

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 발명은 기본적으로 무기질 필러에 의해 형성된 주제 25 ~ 60 중량%; 폴리머 에멀젼에 의해 형성된 경화제 40 ~ 75 중량%;의 혼합에 의해 형성되는 도막방수제 조성물(시멘트 혼입 폴리머계 복합방수제, 폴리머 시멘트계 도막방수제)에 관한 것이다.As shown in Figure 1 or less, the present invention is basically 25 to 60% by weight of the base material formed by the inorganic filler; 40 to 75 wt% of a curing agent formed by a polymer emulsion; relates to a coating film waterproofing composition (cement mixed polymer-based composite waterproofing agent, polymer cement-based coating film waterproofing agent) formed by mixing.

이러한 시멘트 혼입 폴리머계 복합방수제는 물과 분리하여 경화하는 합성수지 에멀젼과 물을 끌어들여 경화하는 성분인 시멘트로 도막방수제가 구성되어 있다. The cement-mixed polymer-based composite waterproofing agent consists of a synthetic resin emulsion that is hardened by separating it from water and a cement that is a component that attracts and hardens water.

일반적으로 합성수지 에멀젼은 고형분 농도가 약 80% 정도이면 경화가 시작되고, 시멘트 성분은 시멘트양에 대해 약 40%의 수분을 취하면 경화하기 시작한다.In general, the synthetic resin emulsion begins to harden when the solid content is about 80%, and the cement component begins to harden when the moisture content of about 40% with respect to the amount of cement is taken.

이러한 폴리머 시멘트계 도막방수제의 투수억제 기능(방수성)은 사용하는 합성수지(EVA계 에멀젼, 공중합 고분자 에멀젼, 아크릴 에멀젼 등)의 성분에 따라 다르기 때문에 어떠한 종류의 수지를 사용할 것인가, 어떤 계열의 분산액을 사용할 것인가가 중요하고, 또한 어떠한 종류의 수경성 시멘트를 사용할 것인가에 따라 크게 영향을 받는다고 할 수 있다.Since the water permeability inhibitory function (water resistance) of these polymer cement-based waterproofing agents differs depending on the components of the synthetic resin (EVA emulsion, copolymer polymer emulsion, acrylic emulsion, etc.) used, what kind of resin to use and what kind of dispersion to use is important, and it can be said that it is greatly affected by the type of hydraulic cement to be used.

합성수지 성분은 본래 소수성이 큰 물질이지만, EVA계 에멀젼 등은 수중에서 분산시키면 물과 잘 섞이고, 이것을 콘크리트 바탕에 바르면 물과 구성성분인 시멘트와 함께 공극으로 스며들어, 농축, 경화하고, 수밀화되어 고화한다.Synthetic resin components are inherently highly hydrophobic, but EVA emulsion mixes well with water when dispersed in water. solidify

이러한 도막방수제와 아스팔트 방수시트가 결합하면 수화열 및 경화에따라 아스팔트 컴파운드와 도막층이 일체화 되어 복합방수층을 형성한다.When this coating film waterproofing agent and the asphalt waterproofing sheet are combined, the asphalt compound and the coating film layer are integrated according to the heat of hydration and curing to form a composite waterproofing layer.

시멘트 성분이 바탕 콘크리트의 공극속으로 침투하여 수화반응을 일으키므로 바탕 콘크리트와 일체화되어 방수재와 바탕재간의 강력한 결합력을 갖게된다.Since the cement component penetrates into the pores of the base concrete and causes a hydration reaction, it is integrated with the base concrete and has a strong bonding force between the waterproofing material and the base material.

따라서 방수재가 콘크리트 모체에 침투하도록 하여 장기적인 미세진동에 의한 콘크리트의 균열이 발생하더라도 침투되어 있는 방수분자가 공극을 메움에 따라 반영구적인 방수를 실현할 수 있고, 자기경화형 시멘트 혼입 폴리머계 방수재의 신장율과 인장성능으로 인해 콘크리트의 미세균열에도 대응한다는 효과가 있다.Therefore, by allowing the waterproofing material to penetrate into the concrete matrix, even if cracks occur in concrete due to long-term micro-vibration, the penetrating waterproofing molecules fill the voids, thereby realizing semi-permanent waterproofing. Due to its performance, it has the effect of responding to microcracks in concrete.

또한, 인체에 무해한 친환경 물질로 이루어져 있어 인체에 유해한 화학물질이 배출되지 않고, 제품의 특성상 일반인도 편리하게 시공할 수 있어 높은 인건비를 줄이고 시공상의 기술적인 문제로 일어나는 하자를 대폭 줄일 수 있다.In addition, since it is made of an eco-friendly material that is harmless to the human body, chemical substances harmful to the human body are not discharged, and the general public can conveniently construct the product due to the nature of the product, thereby reducing high labor costs and significantly reducing defects caused by technical problems in construction.

또한, 비휘발성 제품으로 시공하기 때문에 고유가 시대에 재료비 및 건축자재비를 절감할 수 있다.In addition, since it is constructed as a non-volatile product, it is possible to reduce material and building material costs in the era of high oil prices.
