| Abstract: | Flame-retardant rigid polyurethane foam insulation board was prepared by using perlite as filler.The effects of filling coefficient and particle size of perlite on the composites properties,such as mechanical and thermal conductivity,were investigated.The best filling coefficient of perlite was 40%.To further improve the flame resistant performance of the composites,TCPP and DMMP were used as the additional flame retardants,and the best limiting oxygen index（LOI） was 34.1. |
