이하, 본 발명의 실시를 위한 구체적인 내용을 도면을 참조하여 자세히 설명한다.Hereinafter, with reference to the drawings will be described in detail for the practice of the present invention.
본 발명에 따른 역타설이 가능한 수반응형 탄성 도막재를 이용한 복합방수재는 HDPE 시트(10)와 고무화 아스팔트 도막재(20)와 부직포(30) 및 수반응형 탄성 도막재(40)로 크게 구성된다.The composite waterproof material using the water-reactive elastic coating material capable of reverse casting according to the present invention is largely composed of HDPE sheet 10, rubberized asphalt coating material 20, nonwoven fabric 30, and water-reactive elastic coating material 40. It is composed.
상기 HDPE 시트(10)는 콘크리트 바탕면의 상측부에 설치되며, 강도보강 및 외부 충격으로부터 방수층을 보호한다.The HDPE sheet 10 is installed on the upper side of the concrete base surface, and protects the waterproof layer from strength reinforcement and external impact.
상기 고무화 아스팔트 도막재(20)는 구조물 거동에 대응 가능한 유연성을 확보하고 콘크리트 및 토양에 존재하는 산알칼리로부터 열화되는 것을 방지하기 위한 도막재로서, 상기 HDPE 시트(10) 손상시 자가 차폐가 가능한 자가 치유성을 확보하기 위해 상기 HDPE 시트(10) 상부에 일체로 적층되게 설치하면 되는 것이다.The rubberized asphalt coating material 20 is a coating material for securing flexibility that can respond to the structure behavior and to prevent deterioration from acid alkali present in concrete and soil, and is capable of self-shielding when the HDPE sheet 10 is damaged. In order to secure self-healing, the HDPE sheet 10 may be installed to be integrally stacked.
상기 부직포(30)는 본 발명의 복합방수재의 생산시 균질한 도막두께를 확보하기 위한 재료로서, 상기 수반응형 탄성 도막재(40)와 고무화 아스팔트 도막재(20) 간의 긴밀한 상호결합을 확보하고, 인장강도 및 신장률을 보강할 수 있도록 상기 고무화 아스팔트 도막재(20)의 상부에 일체로 적층되게 설치하면 되는 것이다.The nonwoven fabric 30 is a material for securing a homogeneous coating film thickness during the production of the composite waterproofing material of the present invention, and secures a close mutual coupling between the water-reactive elastic coating material 40 and the rubberized asphalt coating material 20. In addition, the rubberized asphalt coating material 20 may be integrally stacked on the upper portion of the rubberized asphalt coating material 20 so as to reinforce the tensile strength and the elongation rate.
상기 수반응형 탄성 도막재(40)는 상기 콘크리트의 역타설에 따른 부착력확보를 위한 도막재로서, 방수층 설치 후 후속공정이 가능하도록 하고, 표층부 강도 확보에 따른 보행성을 확보할 수 있다.The water-reactive elastic coating material 40 is a coating material for securing the adhesion according to the reverse casting of the concrete, to enable the subsequent process after the waterproof layer is installed, it is possible to secure the walkability by securing the surface layer strength.
이때, 상기 수반응형 탄성 도막재(40)는 기능성 시멘트 10~18 중량%, 규사 미분말 30~40 중량%, 기능성 변성폴리머 35~50 중량%, 점착부여제 5~10 중량%, 착색안료 0.85~1.5 중량%, 기포제 0.05~0.5 중량%, 소포제 0.1~0.7 중량%, 산화방지제 4~10 중량%로 이루어진 무기충전제 파우더를 기계식으로 믹싱 혼합되어 이루어지는 것이 바람직하다.At this time, the water-reactive elastic coating material 40 is 10 to 18% by weight of functional cement, 30 to 40% by weight of fine silica sand, 35 to 50% by weight of functional modified polymer, 5 to 10% by weight of tackifier, pigment pigment 0.85 It is preferable that the inorganic filler powder consisting of ˜1.5% by weight, foaming agent 0.05-0.5% by weight, antifoaming agent 0.1-0.7% by weight, and antioxidant 4-10% by weight is mechanically mixed and mixed.
상기 수반응형 탄성 도막재(40)의 조성시 사용되는 첨가물은 기능성 시멘트(보통 포틀랜드 시멘트, 백색시멘트, 조강 포틀랜드 시멘트도 사용할 수도 있음)와, 기능성 변성폴리머(아크릴계, EVA계를 단독으로 사용할 수도 있음)와, 점착부여제(폴리부덴, PVA계 점착부여제를 사용할 수 있음)와, 기포제 (동물성 기포제, 식물성 기포제/기포 발생량 조절)와, 규사 미분말(배합조건에 따라 6호사, 7호사, 8호사, 파우더 타입으로 사용할 수 있음)을 포함한다.Additives used in the composition of the water-reactive elastic coating material 40 may be functional cements (usually portland cement, white cement, crude steel portland cement may also be used) and functional modified polymers (acryl-based, EVA-based) ), Tackifiers (polybudene, PVA-based tackifiers can be used), foaming agents (animal foaming agent, vegetable foaming agent / foam generation amount control), silica sand powder (No. 6, 7, depending on the mixing conditions) 8, powder type).
여기에서, 상기 기능성 변성폴리머는 고무적인 탄성을 부여함과 동시에 수반응에 따른 점착성을 부여하며, 2차적으로 콘크리트와의 안정적인 부착을 확보하기 위해 점착부여제를 사용한다. Here, the functional modified polymer imparts rubbery elasticity and at the same time imparts tackiness according to the water reaction, and uses a tackifier to secure stable adhesion with concrete.
또한, 상기 착색안료는 색상을 부여하는 기능 이외에도 산화제가 포함되어 자외선 등에 일시 노출되어도 열화되지 않으며, 기능성 시멘트 및 규사 미분말를 적용하여 작업자의 보행 및 후속 작업(철근배근 및 거푸집 설치 작업)이 가능하다.In addition, the coloring pigment is not deteriorated even when temporarily exposed to ultraviolet rays due to the addition of an oxidant in addition to the function to give a color, it is possible to walk and follow-up work (rebar reinforcement and formwork installation work) of the operator by applying a functional cement and silica sand powder.
또한, 상기 기포제는 인위적인 탄성 부여 및 혼입 재료의 균일적인 분산을 위해 상황에 따라 동물성 기포제 또는 식물성 기포제를 사용한다.In addition, the foaming agent uses an animal foaming agent or a vegetable foaming agent depending on the situation for artificial elasticity provision and uniform dispersion of the incorporation material.
따라서, 방수층 시공 후 2차 타설하는 콘크리트 내부에 존재하는 수분에 반응하여 표면 점착성을 확보(접착제 및 토오치 및 열풍기 등 열기구를 사용하지 않고 화학반응에 의한 부착방법)함으로써 콘크리트의 역타설이 가능하며, 표면강도를 확보함으로서 방수재가 외기에 장시간 노출(UV)되거나 장시간 그 상부에서 콘크리트 타설을 위한 철근배근작업 및 작업자의 보행이 가능한 장점이 있다.Therefore, it is possible to reverse-cast concrete by securing surface adhesiveness (adhesive method by chemical reaction without using hot air balloon such as adhesive and torch and hot air fan) in response to moisture existing in the concrete which is poured after the second waterproofing construction. By securing the surface strength, the waterproofing material is exposed to outdoor air for a long time (UV), or reinforcement work for placing concrete in the upper part for a long time, and the worker can walk.
