Technical Field
The invention belongs to an explosion-proof boot, and particularly relates to an impact-resistant explosion-proof boot.
Background
After the landmine explodes in the soil, strong shock waves are generated in the soil. Because the soil has certain porosity, the strong action of the shock wave causes the soil around the mine to be compacted and crushed. More than half of the energy of the shock wave is quickly dissipated and attenuated into a stress wave. The reflection and transmission occurs when the stress wave propagates to the foam interface of the soil and the lightning protection boot sole. The compression wave, reflection wave and subsequent expansion of the gas cause the soil above the charge to loosen, strip and throw, thereby forming an inverted cone shaped blast pit. The boot sole of the explosion-proof boot worn during mine sweeping can be continuously impacted by transmitted waves and a part of explosive gas products, the impact-resistant layer of the boot sole of the explosion-proof boot in the prior art is generally made of high-hardness materials or formed by compounding multiple materials, the strength of the impact-resistant layer can be ensured, the high-temperature impact from bottom to top on the boot sole is blocked by the impact-resistant layer during mine removal, but the impact-resistant layer is difficult to buffer the high-temperature impact while blocking the high-temperature impact, and therefore the protective performance needs to be improved.
