Diaminotetrachlorophenoxycyclotriphosphazene에 의한 Epoxy수지의 경화
Abstract
1,1-Diam intr-3,3,5,5-tetrap henoxycyclorotriphosphasene (APP), 1,3,5-trichloro -1,3,5-trid imethylaminocyclotriphosphazene (Cl3), 1,1-d iam ino-3,3,5,5-tetra- (2,2,2-trifluoroet hoW) cyclotriphosphazene (AFEP), 1,1-d iamino-3,3,5,5-tetra-(p-chlorophenoxy ) cyclotriphosphazene (ACPP)were synthesized from hexachlorocyclotriphosphazene(PNC) and used as curing agent of epoxy prepolymers(Bisphenol A-type, diglycidyl ether EPIKOTE 828, 184-194 g/eq.) The dynamic viscoelastic properties, mechanical properties of the epoxy resin cured by photophazene derivatives were investigated. Considering the rigidity and glass transition temperature of the cured resin, the curing conditions for EPIKOTE 828/ACPP system was found to be 20
