▎ 摘 要
NOVELTY - Wet-graphene polyurethane resin comprises 3-20 wt.% polyester polyol, 3-20 wt.% polyether polyol, 0.5-1 wt.% chain extender, 2-10 wt.% isocyanate, 60-75 wt.% solvent, 0.01-0.1 wt.% graphene, 0.01-0.1 wt.% terminator, and 0.1-0.5 wt.% additives. USE - Wet-graphene polyurethane resin used for synthetic leather. ADVANTAGE - The wet-graphene polyurethane resin is easy to prepare and cost-effective, and has excellent conductivity, and antistatic property. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a wet-graphene polyurethane resin, which involves: (A) making polyester polyol and polyether polyol, chain extender, graphene at 100-120 degrees C, vacuum degree of -0.09--0.1MPa, dehydrating for 1-3 hours; (B) reducing at temperature to 70-80 degrees C, adding solvent, and isocyanate, mixing uniformly, carrying out reaction at 75 degrees C, and adding another portion of the solvent, when the viscosity reaches 200,000-300,000 cps / 25 degrees C; and (C) adding terminator to stop the reaction, and adding auxiliary is added, stirring mixture and discharging to obtain final product.
