Use firemen fire protective rubber boots firefighters the regular personal protective equipment. Wearing the boots into the general scene, the scene of the accident for fire fighting and rescue work. However, strong corrosive liquid, gas, chemical accident scene; the strong permeability agents, biological viruses exist the scene of the accident; charged scene of the accident, can not provide effective protection, and are prohibited from use in these places. Second, situation structure the firefighters extinguishing protective rubber boots by outsole and boots to help two parts, the theme color is black, along the strip accompanied by yellow Wai bars, etc.. Whole boots are made of multi-layer structure. The boots head with a steel header, in order to improve the anti-smashing performance. Inside and outside of Baotou Steel insulated rubber layer foam comfort layer, insulating paper, foam comfort layer and interlock fabric lining with insulation so comfortable to wear. Outsole with steel in the end, in order to improve the performance of anti-piercing, in the the steel bottom up and down both sides of the rubber insulation, insulating paper, foam comfort layer and interlock fabric lining, the beads can be non-slip outsole. The sponge layer from the bottom of the shoe-side to the same port, the increase in the rubber layer and the interlock between the cloth lining, with good insulation resistance, flame resistance, heat insulation, colleagues, can effectively improve the comfort of wearing. Third, the main technical performance, quality, the gumboots quality of the: double firefighters protection less than 3Kg. 2, physical and mechanical properties: mechanical and physical nature of the firemen fire protective rubber boots material basically reached the most advanced level of oil resistance: firemen fire protective rubber boots material sample at a temperature of 23 ℃ ± 2 ℃ # 1 standard oil immersion 24h, the volume change within the range of from -2% to +10%. 4, acid and alkali resistance: firemen fire protective rubber boots material samples were soaked in a temperature of 23 ℃ ± 2 ℃ 3.7mol / L, pH 6.0 mol / L sodium hydroxide solution after 70h ± 2h, physical no significant changes in the mechanical properties. 5, the metal liner corrosion resistance: metallic gasket contact the sample with a concentration of 0.25% aqueous sodium chloride solution after 48h, no corrosion occurs. 6, anti-smashing performance; firemen fire protective rubber boots, boots head after 10.78kN static pressure test and the impact hammer quality 23kg drop height of 300mm impact test, the gap height is not less than 15mm. 7, puncture resistance: firemen fire protective rubber boots outsole anti puncture force of not less than 1100N. 8, cut resistance: the firefighters extinguishing protective rubber boots of the head with a total weight of 800g cut pierced. Electrical insulation properties: firemen fire protective rubber boots breakdown voltage not less than 5000V, and leakage current less than 3mA. 10, the insulation performance: the firefighters extinguishing protective rubber boots insulation performance test is heated 30min, not more than 22 ° C surface temperature rise within the soles. 11, thermal radiation permeability: the firefighters extinguishing protective rubber boots boots surface by radiant heat flux for 10Kw/m2 ± 1 Kw/m2, its inner surface up to not more than 22 ° C irradiation after 1min. 12 waterproof: the firefighters extinguishing protective rubber boots waterproof test water seepage. 13, non-slip performance: the firefighters extinguishing protective rubber boots during non-slip performance test, before sliding angle of not less than 15 °. Four sizes firemen fire protective rubber boots boots No. 39-45 No. 7 kinds of specifications steel the Baotou Steel floor high-grade fireproof material fireproof stab-antisquashy wear comfortable and beautiful oil-resistant anti-static
