/ Polyurea resin agent and waterproofing and sealing method using thereof
According to the present invention, provided is a polyurea resin composition, a two-component composition comprising a main component and a curing agent, in which the main component comprises a two-stage polymerization product having an isocyanate (NCO) structure at the terminal obtained by introducing and mixing 70 to 90 parts by weight of FIRST polyol I (polyether polyol), and 1 to 5 parts by weight of a plasticizer in 100 parts by weight of methylenediphenyl diisocyanate (MDI) in which monomeric MDI and modified MDI are mixed in a volume ratio of 9 : 1, and the curing agent comprises a curing agent mixture manufactured by introducing and mixing, to 100 parts by weight of FIRST polyol II (polyether polyol), 10 to 40 parts by weight of FIRST polyol III (polyether polyol), 30 to 50 parts by weight of diethyltoluenediamine, 1 to 3 parts by weight of an antifoaming agent, and 5 to 12 weight parts of a pigment into a mixer.
본 발명에 의하면, 주제와 경화제로 구성되는 2액형으로서, 주제는, Monomeric MDI와 변성 MDI가 9:1의 부피비 혼합된 메틸렌디페닐 디이소시아네이트(MDI) 100 중량부에 FIRST폴리올 I(Polyether polyol) 70~90 중량부 및 가소제 1~5 중량부가 반응기에 투입 및 혼합되어 말단이 이소시아네이트(NCO) 구조를 가지는 2단 중합 중합물을 포함하고, 경화제는, FIRST폴리올 II(Polyether polyol) 100 중량부에 FIRST폴리올 III(Polyether polyol) 10~40 중량부, 디에틸톨루엔디아민(Diethyltoluenediamine) 30~50 중량부, 소포제 1~3 중량부 및 안료(Pigment) 5~12 중량부가 혼합기에 투입 및 혼합되어 제조된 경화제 혼합물을 포함하는 폴리우레아 수지 조성물이 제공된다.
