Abstract：Reduce the EPS particle size to less than 1mm beads and dispersed the beads into the foamed cement to prepare wall insulation materials. This method can enhance the fireproof performances of EPS-foamed cement composite insulation material and slow down the development of fire after being ignited. The fireproof performances of EPS-foamed cement under different EPS particle size were carried out and the cusp catastrophe model of EPS-foamed cement combustion behaviors were established to study the influence of EPS particle size on the fireproof performances and the development of fire in high temperature furnace. The results show that compared to EPS beads with 2.0～4.0 mm,EPS beads with 0.5～1.0 mm can be used to reduce the pyrolysis rate and the degree of pyrolysis of EPS to enhance the fireproof performances and improve the stability of combustion behavior of EPS-foamed cement to slow down the development of fire.
