CRC Polyurea waterproof agent manufacturing method and waterproof method using polyurea waterproof agend and CRC panel
According to the present invention, provided is a method for producing a polyurea paint film waterproofing agent, the method comprising the steps of: preparing an A solution in which 100 parts by weight of an isocyanate complex is mixed and reacted with 70 to 90 parts by weight of polybutylene oxide glycol, 60 to 80 parts by weight of cyclohexanedimethanol, 50 to 70 parts by weight of ethyl 2-butyl acetoacetate, and 30-50 parts by weight of 2,4,6-tribromophenol, wherein in the isocyanate complex, tetramethylxylene diisocyanate, 4,4-dicyclohexylmethane diisocyanate, 1,4-cyclohexane diisocyanate, toluene 2,6-diisocyanate, and 4,4-methylenediphenyl diisocyanate are mixed at a volume ratio of 1 : 0.8 : 0.6 : 0.5 : 0.2; and preparing a B solution in which 100 parts by weight of an amine complex is mixed with 70 to 90 parts by weight of triethylphosphine, 60 to 80 parts by weight of dimethylamine, 50 to 70 parts by weight of cyclopentene, and 5 to 7 parts by weight of pigment, wherein in the amine complex, 2,4-diaminotoluene and 2,6-diaminotoluene are mixed at a volume ratio of 1 : 0.5. Accordingly, a polyuria paint film waterproofing agent with excellent durability is prepared, and waterproofing with reinforced insulation is achieved by applying the prepared polyuria paint film waterproofing agent to a CRC composite panel.
