[0084] Embodiment 5: like Figure 1-2As shown in the figure, the nuclear protection suit adopts an integrated design, and a double-layer splicing method is used to ensure the isolation of the protective clothing. The seams are heat-sealed and closely matched with other protective parts. The zipper is made of radiation-proof tape, and the zipper is sealed and pulled straight from the neck to the crotch, which is convenient for wearing and removing. There is a protective placket outside the zipper. The clothing corresponds to the general parts of the human body with a single layer of radiation-proof material, and the sensitive parts such as the thyroid gland and reproductive system are superimposed and stitched with multiple layers of radiation-proof materials. The design of the nuclear protection suit is loose, and the front part is sealed from the neck to the crotch with a zipper, and the cuffs and trouser legs are tightly closed with Velcro. The high-performance flexible radiation-proof material layer is made by calendering, with high-strength flame-retardant fabric as the base fabric, and the lead-free shielding agent tantalum, gadolinium, and bromine antimony flame retardant are dispersed in the coating rubber. After a certain thickness is scraped on the base fabric, it is dried and then bonded with the flame-retardant lining cloth to form a radiation-proof material. The thickness of the radiation-proof material is about 4.5mm.

[0085] The thermal insulation suit's thermal insulation jacket, thermal insulation pants, hood and boot covers are an integrated design with good protection. The lower part of the torso is sewn as a whole and sealed with flame-retardant adhesive strips. The jacket is designed with a hood, a face shield, a built-in helmet and a respirator to provide further protection. There is a jumpsuit release along one side of the body from the hood to the lower trousers. The jumpsuit release is closed with a metal flame-retardant airtight zipper and flame-retardant Velcro, and the zipper is wrapped with a bottom tube and an insulated door lapel. Reflective strips are designed on the front chest, back, hands and legs of the clothing. The thermal insulation boot covers are sewn together with the thermal insulation pants, and the stitching pinholes are fully flame-retardant and pressed. The thermal insulation suit adopts an integrated design of thermal insulation jacket, thermal insulation pants, hood and boot covers. The thermal insulation suit is organically combined with multiple fixing methods such as release, zipper and Velcro. The high-temperature steam-proof outer layer is nylon / PE composite aluminum film cloth, the thickness of the aluminum film is about 8μm, and the heat insulation layer is aramid.

[0086] That is to say, the technical solution of Example 5 is basically the same as the technical solution of Example 1, with the only difference being that the high-temperature steam-proof outer layer is a nylon / PE composite aluminum film cloth, the thickness of the aluminum film is about 8 μm, the thermal insulation layer is aramid, the lead-free shielding agent is tantalum and gadolinium, the polymer is rubber, and the thickness of the radiation protection material is about 4.5 mm.

Based on the test results, it can be seen that the nuclear insulation suits according to embodiments 1-5 of the present invention can reduce the kerma rate of gamma rays with an energy of 130keV by more than 70% (radiation protection capability); 300°C high-temperature steam protection, the time for the inner surface temperature to rise to 24°C is ≥60s (anti-radiation heat penetration performance); after the thermal stability test (260°C), the dimensional change rate along the longitude and latitude directions is not more than 10%, No discoloration, delamination, carbonization, melting and dripping; hydrostatic pressure resistance ≥17kPa; after bending 2500 times, there is no delamination or falling off of the composite material or fiber, the warp and weft breaking strength of the nuclear protection clothing material is ≥500N (bending resistance), the warp and weft breaking strength of the thermal insulation clothing material is ≥500N; wear resistance ≥100 times; warp and weft breaking strength ≥650N; warp and weft tearing strength ≥100N; warp and weft peeling strength ≥9N / 30mm; damage length ≤100mm, afterburning time ≤2s, and no melting or dripping (flame retardant performance).

[0088] The nuclear-proof thermal insulation suit according to the embodiment of the present invention can be used alone or worn together, and is easy to put on and take off. It has limited protection against medium and low energy gamma rays when worn, can withstand high temperatures for a limited time, and has excellent comprehensive protection performance.

[0089] The manufacturing process technology of the emergency rescue nuclear-proof thermal insulation suit with both radiation protection and steam protection functions according to the present invention is mature and reliable, easy to mass produce, and can be widely used in the fields of emergency repair and rescue protection in high-temperature steam and nuclear radiation scenarios.
