| Abstract: | The cone calorimeter was used to study the combustion characteristics of rigid polyurethane foam(RPUF).The effects of polyether polyol,polyester polyol and R value on heat and gas hazards were discussed by systematically testing the heat release rate,total heat release,smoke production rate and total smoke production rate during the combustion process of polyurethane foam.The results showed that the HRR,THR,SPR and TSPR during the combustion process of RPUF prepared by replacing polyether polyol with polyester polyol were greatly reduced.Meanwhile,increasing the R value of polyurethane foam were helpful to reduce the fire hazard. |
