Preparation and Study of a New Polyurethane Curing Agent

Abstract:

A new environmentally friendly polyurethane curing agent was prepared by the method that cyclic carbonate reacted with isophorone diamine. Investigated the synthesis temperature of the curing agent by DSC and FT-IR, and discussed membrane mechanical properties by curing agent and thermal properties of membrane. The results showed cyclic carbonate reacted violently with isophorone diamine in 82 °C, and the carbamate group appeared on molecular chain; breaking strength of the film and given elongation modulus was greatly improved by using this curing agent.
