A Research on Development of Eco-friendly Polyurethane Waterproofing Membrane Coating of Exposed Type

재활용 소재를 활용한 친환경 노출형 폴리우레탄 도막방수재 개발에 관한 연구

The subject of this study, Eco-friendly Polyurethane Waterproofing Membrane Coating of Exposed Type is manufactured by replacing environmental hazardous substance such as Toluene, Dioctyl Phthalate with Dimethyl Carbonate, waste-soybean oil. As part of existing filler is also replaced with waste-rubber chip and waste-soybean oil. As a result of environment friendly tests, in test of detection of VOCs case was contented with the Ministry of Environment standards at 5% below. Testing methods for heavy metal extracted was contented with standards for official wastes test method. So it is judged that environment friendly is secured.
