摘　　要：The coated fiberglass fabric was prepared to protect personnel and equipment from sparks, heat, and molten metals during hot work projects. Ferric oxide powder 2%,mica powder6%,wollastonite powder 4%,and white carbon black 8% were added in the phenyl methyl silicone to prepare the composite silicone solution. The french chalk and coupling agent can effectively solve the deposition of fillers in the coating solution. Compared with the original fiberglass fabric,heat resistance of the coated fabric under high temperature was greatly improved, and the temperature limitation in short period was higher than 900℃. Horizontal flammability tests showed that the coated fabric was non-combustible with no melting and no fragments. The temperature for long period usage of coated fabric was lower than 500 ℃. Welding drop test showed that the coating could prevent the molten metals,sparks and heat from transferring in the fabric. Test for toxic gas release showed that the toxic gases such as HCN,SO_2,HCl,and HF were not detected,only CO( 100 mg / m^3) and NO( 12 mg /m^3) were detected,and their concentrations were far lower than the limitation values CO( 4 375 mg / m^3) and NO( 134 mg /m^3). The breaking strength of coated fabric was almost twice the strength of the original fabric,and the coated surface had good water and oil repellency.The coated fiberglass fabric was prepared to protect personnel and equipment from sparks, heat, and molten metals during hot work projects.
