Abstract

In order to meet the requirements of fire resistant and heat insulation funtions of fire protection clothing and protect firemen's personal safety, 6. 5 μm and 7. 0 μm aluminum foils were combined with basalt and glass fiber to prepare heat-resistant and heat-insulating materials. The thermal stability of base cloth and composites was tested by thermogravimetric (TG) analyzer. The reflection and transmission performance of single reflection layer and its interlayer were tested by spectrometer, and performance of thermal shock resistance of laminated materials was studied by using fabric adiabatic test devices. The results show that the average reflectivity and transmittance of 6. 5 μm aluminum foil in all band (240 - 2 600 nm) are 90. 34% and 0. 023% respectively, that the average reflectivity of 7. 0 μm aluminum foil and basalt fabric composite is 90. 23% and the transmittance is 0. 025%, and that in flame thermal shock tests, 6. 5 μm aluminum foil and basalt fabric composit has the best performace of thermal shock resistance which can hold for 400 seconds at 600-800 ℃ high temperature, and the average temperature difference between the positive and negative surface of the sample is 511 ℃, which shows that 6. 5 μm aluminum foil and basalt fabric composite is a good thermal insulation material. © 2019 China Safety Science Journal
