The development of low-cost flame retardant and thermal insulation fabrics to replace expensive high-performance fiber fabrics is of positive significance for the popularization of household fire-fighting equipment and reducing the cost of fire-fighting clothing.In this paper,on the basis of the regulation of the surface structure of inorganic nanoparticle materials and the surface treatment of glass fiber,the thin layer coating of viscoelastic material on glass fiber fabric is realized by foam finishing,and through the surface treatment of aluminum hydroxide and glass fiber fabric,it ensures that sufficient heat insulation materials are applied on the surface of glass fiber fabric,and the rubbing fastness of aluminum hydroxide and organic polymer on the surface of fiberglass fabric and the flame retardancy and thermal protection of the fabric are improved.As a result,the flame retardant and heat insulating protective fabric is prepared,the carbon length after combustion is 2.0 mm,the smoldering and reburning time is 0,and there are no solution droplets.The thermal protection property of the fabric is 35.80 J/cm2·s,which reaches the thermal protection level of aramid.In addition,the dry friction fastness of the functional layer of the fabric is grade 4,and the wet friction fastness is grade 3.
