The invention discloses a high-temperature-resistant heat-insulating
protective garment and a preparation process thereof, and relates to the field of protective garments, and the high-temperature-resistant heat-insulating
protective garment is prepared by selecting a polysulfonamide fabric, performing
flame-retardant finishing by using an after-finishing
flame retardant, soaking the polysulfonamide fabric in an anti-static liquid, dipping,
drying, and
coating the surface of the fabric with a
polytetrafluoroethylene coating, thereby obtaining the high-temperature-resistant heat-insulating
protective garment. The anti-static breathable layer, the heat
insulation layer and the
flame-retardant layer are sequentially compounded, and the problems that an existing protective garment is poor in heat insulation performance, cannot well block
heat energy outside the protective garment and is not ideal in flame-retardant effect are solved; the compounding of organic and
inorganic materials can realize complementary advantages, and gives consideration to the
mechanical property, weaving property, heat insulation and
open fire resistance of polysulfonamide, so that the heat insulation property of the fabric is improved, the flame-retardant layer can prevent
combustion products from escaping and inhibit
thermal decomposition of materials under the layer, the flame-retardant, low-
smoke and low-
toxicity effects are achieved, a cracked
carbon layer is formed on the surface of the polysulfonamide, and the flame-retardant, flame-retardant and flame-retardant effects are achieved. And the
oxidation resistance of the cracked
carbon layer is improved, so that the flame-retardant purpose is achieved.
