Existing alkali-resistant work clothing mostly passively isolates alkaline substances from the body, protecting workers from corrosion. However, this type of protective clothing is only suitable for normal production work. If alkaline materials leak and create an alkaline environment, such protective clothing only protects the workers themselves and cannot eliminate or improve the acid-base environment created by the alkaline substances. Furthermore, if such protective clothing is damaged by foreign objects, its isolation effect will be lost, thus losing its protective effect. Summary of the Invention

[0037] To further improve the protective performance of the protective clothing, the top 1 and the bottom 2 both include a shaping layer, a protective layer, a barrier layer, a conductive layer, and an inner lining layer, which are arranged in sequence from the outside to the inside. The shaping layer is made of a flexible, breathable and liquid-permeable material, the protective layer is an acid- and alkali-resistant absorbent sponge 9, and the barrier layer and the inner lining are both made of a flexible, gas- and liquid-isolating material.

[0038] A plurality of seepage components are evenly distributed in the protective layer, and the seepage components penetrate the acidic liquid in the liquid storage tank 5 into the absorbent sponge 9. A hose net 14 is provided in the conductive layer, and the liquid inlet end of the hose net 14 is connected to the liquid storage tank 5, and the liquid outlet end of the hose net 14 is connected to the nozzle 6 and the seepage component.

[0039] In order to optimize the product structure, in this embodiment, the seepage component includes a seepage tube 15, a baffle 16 and a liquid bag 17. The seepage tube 15 is in the shape of a circular tube. The liquid bag 17 is made of an elastic acid-resistant and alkali-resistant material and is connected to one end of the seepage tube 15. The liquid bag 17 is connected to the hose net 14. The circumferential side wall of the seepage tube 15 is provided with a plurality of seepage areas in a circumferential array. The seepage areas are evenly distributed with multiple seepage holes. The baffle 16 includes an end plate and a plurality of baffles.
