AI Technical Summary
Existing thermosetting polymer foam resins have low flame retardancy, degraded material properties, and poor environmental performance, making it difficult to meet increasingly stringent fire safety standards and green development trends.
By employing low-temperature gas-phase, medium-temperature expansion, and high-temperature skeleton flame retardants, as well as the composite of active hydrogen flame retardants and fluorosiloxanes, synergistic flame retardancy is achieved through temperature gradient, combined with surface modification treatment of fluorosiloxanes, thereby improving the compatibility and stability of the flame retardants and resins, forming a porous isolation layer and a char layer for protection.
It achieves a fire rating upgrade from Class B to Class A without significantly affecting material performance. It possesses highly efficient, environmentally friendly flame-retardant properties and good compatibility with resin, meeting current industry needs.
