Abstract

Abstract: A phenolic foam was prepared by using a mixture of p-toluenesulfonic acid, sulfuric acid and muriatic acid as a curing agent, and the effects of polyethylene glycol, foam stabilizer, curing agent and the content of foaming agent on the structure and properties of the foam were investigated. The results indicated that the structure and properties of the foam could be optimized when the foaming temperature was set to 60 ℃ and the contents of PEG, foaming agent, curing agent and surfactant were set as 10 %, 15 %, 8 % and 5 wt %, respectively.
