Preparation and Performance Investigation of Phenolic Foam

A phenolic foam(PF) with excellent performance was prepared with the raw materials containing of non-fluorine complex foaming agent,organic and inorganic acid complex curing agent, surfactant twain-80 and self-regulating phenolic resin.The effects of curing temperature,curing agent, foaming agent on curing time,apparent density,compression strength,thermal conductivity and oxygen index of PF were investigated.The optimal technological parameters were obtained.This has important guiding significance for preparation and modification research of PF
