Abstract

The invention discloses a preparation method of a polyurethane material for anti-static shoes. The method comprises the following steps: (1) hydroformylation: filling microalgae grease, rhodium dicarbonyl acetylacetonate (I) and triphenylphosphine into a quartz lining, and then putting the quartz lining into a high-pressure reaction kettle to obtain a reaction mixed solution; (2) hydroformylation: adding absolute methanol and a catalyst into the reaction mixed solution, and then putting into a high-pressure reaction kettle; and (3) addition polymerization: mixing the bio-based polyol, a tertiary amine catalyst, an organic tin catalyst, a surfactant, a foaming agent, an auxiliary foaming agent and a flame retardant to obtain the polyurethane material. According to the preparation method of the polyurethane material for the anti-static shoes, the step design is reasonable, the microalgae grease is used as the raw material, the bio-based polyol is prepared through a hydroformylation-hydrogenation reduction method, consumption of fossil resources is reduced, the polyurethane material is more environmentally friendly and sustainable, the prepared polyurethane material can serve as a scattered electricity material to be used for soles of the anti-static shoes, and the fireproof and flame-retardant capabilities are improved.

Description

technical field [0001] The invention belongs to the technical field of polyurethane materials, and in particular relates to a preparation method of polyurethane materials for antistatic shoes. 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. Wait. [0003] Anti-static shoes usually use dissipative material PU (polyurethane material) or PVC m...
