High-temperature-resistant heat-insulating protective clothing and preparation process thereof

Abstract

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.

Description

technical field [0001] The invention relates to the field of protective clothing, in particular to a high-temperature-resistant heat-insulating protective clothing and a preparation process thereof. Background technique [0002] As the most important type of protective equipment, thermal protective textiles can reduce the temperature rise rate of the wearer's skin in a high-temperature environment, thereby avoiding or reducing various heat damage to the human body, so that high-temperature workers can effectively perform in a certain high-temperature environment. task, or to prolong the time of resisting heat damage so that victims in distress can successfully escape from the high temperature environment. It is suitable for special industries such as fire protection, cutting, welding, power plants, steel plants, maintenance of petrochemical enterprises, coking in the furnace, front operation of the furnace, etc. For special types of work, protective clothing can greatly slow...

AI Technical Summary

Problems solved by technology

[0005] (1) Select the aramid sulfonamide fabric, use the post-finishing flame retardant for flame retardant finishing to obtain a flame retardant layer, soak the aramid fabric in antistatic liquid, dip, dry, and coat a layer of polyester on the surface of the fabric Tetrafluoroethylene coating, drying, to obtain an anti-static air-permeable layer, the anti-static air-permeable layer, heat-insulating layer and flame-retardant layer are sequentially compounded, and the compounded fabric is cut according to the size specification of the protective clothing, and clothing is obtained to obtain an anti-static air-permeable layer. High-temperature heat-insulating protective clothing solves the problem that the existing protective clothing has poor heat insulation, cannot well block heat energy from the protective clothing, and the existing protective clothing has an unsatisfactory flame-retardant effect;
