AI Technical Summary

Technical Problem

Existing technologies struggle to provide a single catalyst that combines high steric hindrance, HFO compatibility, gel selectivity, reactivity, low emissions, simple synthesis process, and good economics. They cannot simultaneously meet the comprehensive requirements of HFO rigid polyurethane foam for long-term storage stability, excellent flowability, and mechanical properties.

Method used

A novel sterically hindered reactive tertiary amine catalyst was prepared by reacting organic amine compounds with urea or alcohol/ether compounds through a specific structure. This catalyst exhibits both high steric hindrance and high gel selectivity and can be used in polyurethane systems with HFO-based environmentally friendly foaming agents.

Benefits of technology

This study comprehensively improves the stability, flowability, and mechanical properties of HFO rigid polyurethane foam during long-term storage, avoids the deactivation and uneven reaction problems of traditional catalysts, and meets environmental protection requirements.
