Abstract

The present invention provides a waterproof coating material for blocking radon. The waterproof coating material for blocking radon is composed of 10 wt% of SEBS copolymer, 85 wt% of solvent, and 5 wt% of SIS copolymer. To produce the waterproof coating material for blocking radon, the SEBS copolymer is added to the solvent at 40 to 50°C and is stirred for 60 to 150 minutes to be dissolved. The SIS copolymer is added and stirred for 60 to 150 minutes to be dissolved. According to the present invention, a waterproofing material is firstly permeated by spray coating on a concrete surface to block pores of concrete, thereby preventing harmful gas caused by radon and preventing fine dust scattering and odor due to asbestos. At the same time, since a thin vinyl coating film (rubber film) is formed on the surface and is covered secondarily, the efficiency of the blocking effect is increased, and a thermal insulation effect and a waterproof function by the coating film can be expected. The waterproof coating material for blocking radon is highly elastic to prevent microcracks on a structure and to strengthen the surface. In addition, an economical effect can be expected because maintenance is not required with a long lifetime.

라돈 차단 방수 코팅재{Waterproofing material for blocking radon}Waterproofing material for blocking radon

본 발명은 라돈 차단 방수 코팅재에 관한 것으로, 더욱 상세하게는 콘크리트 표면 등에 뿜칠 시공을 함으로써 방수재가 1차로 침투되어 콘크리트의 공극을 막아 라돈으로 인한 유해가스 차단과 함께 석면으로 인한 미세먼지 비산 및 냄새 방지와 동시에 표면에 엷은 비닐 코팅막(고무막)을 형성하여 2차로 차폐시키므로 차단효과의 효율성을 증대시킬 뿐더러 상기 코팅막에 의한 보온효과 및 방수기능을 기대할 수 있고, 고신축성으로 구조물의 미세균열을 방지함과 더불어 표면을 강화하며, 긴 수명으로 유지관리가 필요치 않아 경제적인 효과를 기대할 수 있도록 하는 라돈 차단 방수 코팅재에 관한 것이다.The present invention relates to a radon-blocking waterproof coating material, and more particularly, to a waterproof coating material which is sprayed on a concrete surface or the like to prevent air pollution caused by radon, (Rubber film) is formed on the surface to shield the second layer. Therefore, not only the efficiency of the blocking effect is increased but also the effect of keeping the insulation by the coating film and the waterproof function can be expected and the microcracks of the structure are prevented by the high elasticity And a radon blocking waterproof coating material which can provide economical effects because it does not require maintenance with a long lifetime.

일반적으로 라돈(Re-222)은 지구상에서 발견된 약 70여 가지의 자연방사능 물질 붕괴시 생성되는 물질로서 폐암 발병의 위험이 있는 알파선을 방출하는 가스 상의 물질에 해당하므로 지하실, 아파트, 다중 이용시설을 포함한 모든 지하 및 지상 구조물 및 건물의 경우 높은 농도로 존재할 가능성이 있다.Radon (Re-222) is a substance generated from the collapse of about 70 natural radioactive materials found on the earth. It is a gas-like substance that releases alpha rays that are at risk of lung cancer. Therefore, In the case of all underground and overground structures and buildings,

따라서 이런 종류의 구조물 또는 건물에서는 주기적으로 라돈 농도를 측정하는 것이 필요하다고 할 수 있다. 특히 시멘트 콘크리트의 가옥 구조가 주류를 이루고 있는 현 상황에서 건축용 골재나 건자재 또는 시멘트 콘크리트에서 라돈이 방출되고 있는바, 새집증후군(sick house syndrome) 이외에 오래된 실내 주거환경에서도 라돈 방사선 방출에 의하여 보건환경은 심각하게 위협받고 있다.Therefore, it is necessary to periodically measure the radon concentration in this type of structure or building. Especially, in the present situation where the house structure of cement concrete is mainstream, radon is released from the aggregate of buildings, building material or cement concrete. In addition to the sick house syndrome, It is seriously threatened.

실내 공기질 중에서 라돈의 농도는 "다중 이용시설 등의 실내 공기질 관리법"을 근거로 하여 4 pCi/L를 관리 기준으로 정한 바 있으며, 한국 원자력 안전기술원(KINS)은 전국 3,866 가구를 대상으로 실내공기의 라돈가스 농도를 측정한 결과 3.4%가 환경부의 실내 공기질 기준치를 초과했다고 밝혔다.The concentration of radon in the indoor air quality was set at 4 pCi / L as the management standard based on the "indoor air quality management method of multi-use facilities, etc." and KINS (Korea Institute of Nuclear Safety) According to the result of measurement of the concentration of lardon gas, 3.4% of them exceeded the indoor air quality standard of the Ministry of Environment.

또한, 서울 지하철 승강장 및 대합실 44곳을 경희대 대기오염연구실(김동술 교수님팀)에서 측정한바 승강장 가운데 5곳과 대합실 중 4곳이 기준치를 초과하였다.In addition, the Seoul subway platform and 44 waiting rooms were measured by Kyunghee University Air Pollution Research Laboratory (Professor Kim Dong-shik), and five of the platforms and four of the waiting rooms exceeded the standard.

따라서 라돈 농도가 높게 측정된 겨우 라돈 방출률에 근거한 라돈 저감화 시공이 요구된다고 할 수 있다.Therefore, it can be said that radon reduction construction based on the radon release rate is required when the radon concentration is measured high.

현재 국내에서 사용하고 있는 실내에서의 라돈 저감화 방법에는, 건물의 틈새를 통하여 들어오는 라돈 가스를 막기 위하여 실링제로서 틈새를 막거나 자주 환기를 시키는 방법 또는 먼지에 부착되어 흡입되는 라돈 가스를 라돈자핵종의 제거효율이 높은 공기 정화기로써 줄이는 방법 등이 있다.The indoor radon reduction method currently used in Korea includes a method in which a gap is blocked or frequently ventilated as a sealing agent in order to prevent radon gas entering through a gap in a building or a method in which a radon gas sucked and adhered to dust is radon- And a method of reducing the air cleaning efficiency of the air purifier.

그러나 건물의 틈새 외에 콘크리트 벽면 및 천정에서 방출되는 라돈 가스에 대해서는 건물 시공 시 라돈차단제(국내등록특허 제10-454753호)를 콘크리트에 첨가하여 라돈의 방출 속도를 억제시키는 방법을 사용하더라도 라돈가스 방출율의 차단 효과는 30%를 넘지 않고 있다.However, the radon gas emitted from the concrete wall and the ceiling in addition to the clearance of the building, even if the radon blocker (Korean Patent No. 10-454753) is added to the concrete during the building construction to suppress the release rate of radon, The blocking effect does not exceed 30%.

또한, 콘크리트 벽면 및 건자재에 바르는 마감재(국내등록특허 제10-65004호)를 사용하더라도 라돈 차단력은 52% 정도이며, 환기 또는 공기정화기에 의존하는 것은 그 효과가 크지 않을 뿐만 아니라 한계가 있는 방법에 해당한다고 할 수 있으므로 경제적 손실이 발생할 것이라 예상할 수 있다.In addition, the use of the finishing material applied to the concrete wall and the building materials (Domestic Registration No. 10-65004), the radon blocking power is about 52%, and depending on the ventilation or air purifier, It can be expected that economic loss will occur.

이에 본 출원인은 수많은 연구와 노력 끝에, 한번 뿌리거나(뿜칠 시공) 롤러로 문지르는 간단, 간편한 시공으로 라돈의 차단효과를 극대화할 수 있도록 하는 본 발명 라돈 차단 방수 코팅재를 개발하기에 이르른 것이다.The inventors of the present invention have developed a radon blocking waterproofing coating material of the present invention which can maximize the radon blocking effect by a simple and simple operation of spraying (rubbing) and rubbing with a roller after a lot of research and efforts.
