Project Background:
The XPSF used in external thermal insulation composite systems is extremely flammable and poorly bonded with adhesive mortar. Traditional addition of flame retardants and application of surfactant affect the performance of XPSF and the convenience of construction. Therefore, the UV curable coating is innovatively prepared to improve both these performances simultaneously. The modification coating is efficient, environmentally friendly and convenient, promoting the secure application of XPSF.
Aims & Goals:
To obtain multifunctional UV curable systems by preparing new P-N synergistic flame retardant monomers and hollow nanoparticles containing transition metals.
To investigate the flame retardant performance and mechanism of XPSF modified with UV coating.
To study the bonding behavior and mechanism between modified XPSF with adhesive mortar.
