Abstract

The invention discloses a manufacturing method of an anti-static shoe sole free of humidity dependence. The manufacturing method of the anti-static shoe sole free of humidity dependence comprises thefollowing steps that a polyurethane sole material A is mixed with metal fiber according to the mass ratio of 100:0.3-0.8, the metal fiber is evenly dispersed in the polyurethane sole material A, and then a conductive material A is obtained; the conductive material A is heated to 45-50 DEG C, a polyurethane sole material B is heated to 35-40 DEG C, and the heated conductive material A and the heated polyurethane sole material B are mixed at an equal ratio, and then conductive sole material is obtained; according to the dimension of the shoe sole, the conductive sole materials with the amount equal to the dimension of the shoe sole is poured into a preheated mold; the temperature and pressure are kept, demolding and finishing are conducted, the obtained product is placed in a vulcanization box to be vulcanized, and then the anti-static shoe sole free of humidity dependence is obtained. The invention further discloses an anti-static shoe comprising the anti-static shoe sole free of humidity dependence. The manufactured anti-static shoe sole free of humidity dependence has the characteristics of being comfortable and conductive permanently and keeping the conductive intensity constant.

Description

technical field [0001] The invention belongs to the technical field of antistatic shoes, and in particular relates to a non-humidity-dependent antistatic sole, a preparation method thereof, and an antistatic shoe. Background technique [0002] Anti-static shoes are a kind of work shoes worn by production workshops and advanced laboratories of microelectronics industries such as electronic semiconductor devices, electronic computers, electronic communication equipment, and integrated circuits to reduce or eliminate electrostatic hazards. Anti-static shoes can guide static electricity from the human body to the ground, thereby eliminating static electricity on the human body, and at the same time effectively suppress the dust generated by people walking in the clean room. They are suitable for clean workshops and laboratories in pharmaceutical factories, food factories, and electronics factories. and other occasions. [0003] Existing antistatic soles are usually added with a...
