Description
본 발명은 차열성능을 갖는 도막방수재 및 그 제조방법에 관한 것으로, 보다 상세하게는 차열성능이 우수한 진공 세라믹 분말을 사용하여 수용성 아크릴 고무계 에멀젼의 접착강도 및 인장강도를 향상시키고, 충진제 및 무기안료, 진공 세라믹 분말의 접착성을 향상시키기 위해 가수분해된 실란 커플링제를 사용하는 차열성능을 갖는 도막방수재 및 그 제조방법에 대한 것이다.More particularly, the present invention relates to a coating film-waterproofing material having a heat-shielding performance and, more particularly, to a method for improving adhesion strength and tensile strength of a water-soluble acrylic rubber emulsion by using a vacuum ceramic powder having excellent heat- The present invention relates to a coating film waterproofing material having a heat insulating performance using a hydrolyzed silane coupling agent to improve the adhesion of a vacuum ceramic powder and a method for producing the same.
일반적으로 콘크리트 구조물의 수명은 50년으로 알려져 있지만, 신축 후 시간이 지나면서 지반 침하 및 외부충격, 급격한 기후변화 및 풍화작용 등으로 균열 혹은 크랙 등이 발생하여 수명이 단축되고 있다.Generally, the lifespan of concrete structures is known to be 50 years. However, as time elapses after the expansion and contraction, cracks or cracks occur due to subsidence, external impact, rapid climate change and weathering.
따라서, 콘크리트 구조물에 누수현상이 일어나는 경우 보수 또는 건축 신축시 향후 발생될 수 있는 누수 등을 미연에 방지하기 위해서 콘크리트 구조물의 방수처리가 요구되고 있다.Therefore, waterproofing of concrete structures is required to prevent water leaks that may occur in the future when water leakage occurs in concrete structures.
최근 에너지 생산시 발생하는 이산화탄소에 기인한 온실효과로 기후의 이상현상이 발생하고 있으며, 선진국을 비롯한 대부분의 국가에서 이산화탄소의 발생량을 감소시키기 위한 정책을 시행중이며, 특히, 콘크리트 건축구조물에 있어서 태양의 복사열을 효과적으로 차단, 반사하는 원리를 이용해 건축물의 표면온도를 낮춤으로 냉/난방에 필요한 에너지를 저감시켜 이산화탄소의 배출량을 저감시킬 수 있는 도료 및 옥상용 방수재의 개발이 요구되고 있다.Recently, climate anomalies are occurring due to the greenhouse effect caused by carbon dioxide generated in energy production. In most countries including developed countries, policies are being implemented to reduce the amount of carbon dioxide generated. In particular, It is required to develop a paint and a roof waterproofing material capable of reducing the amount of carbon dioxide emission by reducing the energy required for cooling and heating by lowering the surface temperature of the building by using the principle of effectively shielding and reflecting radiant heat.
일반적으로 콘크리트 구조물의 전통적인 방수공법인 도막방수 공법에 있어서 우레탄 공법은 시공 초기에 색상이나 미관이 화려하고 방수기능이 양호하지만, 우레탄 수지가 자외선 노출시 4 ~ 5년 이후 산화되어 강도가 약해지고, 탄성을 잃어 콘크리트 구조물에 균열 및 크랙이 발생되는 경우 갈라지는 현상이 발생하여 방수기능을 상실하는 문제점이 있다.Generally, in the conventional waterproofing method of the concrete structure, the urethane method is excellent in the color and the aesthetics at the beginning of construction and is good in waterproof function, but the urethane resin is oxidized after 4 to 5 years when exposed to ultraviolet rays, When cracks and cracks are generated in the concrete structure, the waterproofing function is lost due to the cracking phenomenon.
또한, 시공시 콘크리트 표면에 소량의 수분이 존재하는 경우 기포 발생 및 도막이 부푸는 현상이 발생하는 문제점이 있다.In addition, when a small amount of water is present on the concrete surface at the time of construction, there is a problem that bubbles are generated and the coating film is swollen.
에폭시 수지 공법도 자외선 노출에 의해 쉽게 산화되어 도막층의 수명이 짧고, 충격이나 기온변화 등에 의하여 쉽게 갈라지는 현상 등의 발생하고 있다.The epoxy resin method is also easily oxidized by exposure to ultraviolet rays, shortening the lifetime of the coating layer and easily cracking due to impact or temperature change.
최근에는 도막방수재에 차열 및 단열 특성을 부여하기 위해 우레탄 및 에폭시 수지에 세라믹 중공체 분말을 일정비율로 첨가하여 혼합교반한 후 콘크리트 슬래브의 바탕면에 고무헤라, 롤러, 스프레이 등으로 적층하여 방수층을 형성시키고 있다. 하지만, 초기에는 방수성능, 차열 및 단열 성능이 우수하지만 사용년수가 증가함에 따라 자외선에 노출된 도막이 열화하여 방수기능이 상실되는 문제점이 발생한다.In recent years, ceramic hollow powder is added to urethane and epoxy resin in a certain ratio in order to impart heat and insulation properties to the coating film waterproofing material, and then the mixture is agitated and laminated on the base of the concrete slab by rubber sheath, roller, spray, . However, in the early stage, the waterproof performance, the heat shielding and the heat insulation performance are excellent. However, as the number of years of use increases, the coating film exposed to ultraviolet rays deteriorates and the waterproof function is lost.
또한, 도막의 주체인 유성의 우레탄 수지 및 에폭시 수지의 사용은 휘발성유기화합물이 다량 포함되어 있어 건강에 헤롭고, 사용하지 않은 제품을 장시간 옥외 노출시 화재 및 폭발의 위험을 갖고 있어, 최근들어 도막의 주체를 수용성 에멀젼을 사용한 환경친화적인 1액형의 다양한 도막방수재가 개발되어 경제적이고 사용하기 편리한 장점을 제공하고 있다. 하지만, 방수성능 및 강도가 유성 우레탄 및 에폭시 수지에 비해 현저히 떨어지는 문제점이 있다.Further, the use of oily urethane resin and epoxy resin, which are the main components of the coating film, is hazardous to health because it contains a large amount of volatile organic compounds, and there is a risk of fire and explosion when exposed to a long- The present invention provides an economical and easy-to-use advantage that a variety of environmentally friendly one-pack type waterproofing materials using a water-soluble emulsion have been developed. However, there is a problem that the waterproof performance and the strength are significantly lower than those of the oil-based urethane and epoxy resin.
상기의 문제점을 해결하기 위한 본 발명은 콘크리트 건축물의 옥상에 사용하는 도막방수재에 차열성능을 부여함으로써 냉/난방 에너지 사용량을 저감시킴으로 이산화탄소 배출량이 절감될 수 있도록 하는 것을 목적으로 한다.In order to solve the above problems, it is an object of the present invention to reduce the amount of cooling / heating energy used by giving a heat shielding performance to a coating material used in a roof of a concrete building, thereby reducing carbon dioxide emissions.
