Polyurea-based sheet for waterproofing and waterproofing construction method using the same
The present invention relates to a polyurea-based sheet and a waterproofing and anticorrosive construction method using the same and, more particularly, to a polyurea-based sheet for waterproofing and anticorrosion which is formed by curing a combination of a main ingredient and a curing agent. The main ingredient includes 35 to 55 parts by weight of a polyamine mixture, 20 to 30 parts by weight of a crosslinking agent, 7 to 12 parts by weight of an inorganic filler, 5 to 10 parts by weight of glass milled fibers, 5 to 10 parts by weight of a metallic ceramic pigment, and 6 to 9 parts by weight of additives. The curing agent is obtained by reacting 60 to 80 parts by weight of an isocyanate mixture and 20 to 40 parts by weight of epoxidized hydroxyl-terminated polybutadiene (EHTPB) at 60 to 100℃ for two to three hours.
본 발명은 폴리우레아계 시트 및 이를 이용하는 방수·방식 시공방법에 관한 것으로, 더욱 상세하게는 폴리아민 혼합물 35 내지 55 중량부, 가교제 20 내지 30 중량부, 무기 필러 7 내지 12 중량부, 글라스 밀드 파이버(glass milled fiber) 5 내지 10 중량부, 금속계 세라믹 안료 5~10 중량부 및 첨가제 6~9 중량부를 포함하는 주제와, 이소시아네이트 혼합물 60~80 중량부, 에폭시화 하이드록실말단 폴리부타디엔(Epoxidized Hydroxyl-Terminated Polybutadiene, EHTPB) 20 내지 40 중량부를 60~100℃에서 2~3시간 동안 반응시켜 얻어지는 경화제의 배합으로 경화되어 형성되는 것을 특징으로 하는, 방수·방식용 폴리우레아계 시트를 개시한다.
