摘要: To study the effect of surfactants on foaming behavior phenol–urea–formaldehyde foam, silicone oil (Dow Corning DC-193) and Tween-80 were selected to their effects mechanical properties, microstructure, combustion characteristics foams. The results show that surface tension resins decreased with increasing surfactant concentration. Both temperature capacity foam first increased then compressive strength oxygen index concentration, which is probably related foam. microstructure foams showed average pore diameters combination DC-193 significantly improved strength, uniformity cells, number closed cells in final product.
