At the same time also cant achieve reassuring safety standards. Research and development new composite insulation fire wall material became the primary problem of construction safety. This article will first use tapered calorimeter and oxygen index to the current main use food several fire prevention heat preservation material (phenolic resin, rock wool, glass fiber grid cloth, inorganic flame retardant insulation mortar) and the compound material of the improved fire burning performance characteristics and characterized. In the most can reflect the real fire scene 50 kW/m2 thermal radiation fluxes conditions, based on these result of phenolic resin, rock wool, [(glass fiber grid cloth) + phenolic resin + rock wool], [(glass fiber grid cloth) + rock wool + phenolic resin] the maximum heat release rate and total heat ,we can think of phenolic resin and rock wool all have certain fire prevention sex, including rock wool non-combustible better performance; will the compound, can further enhance the overall watery resistance. Finally, according to the wall heat preservation material into the summary, and its application in the future was analyzed. Keywords: building structure wall th
