▎ 摘　　要

NOVELTY - Graphene-organosilicon modified polyurethane aqueous coating comprises 38-80 pts. wt. water-based urethane resin modified with graphene-organosilicon, 3-8 portions propylene glycol monobutyl ether, 0.5-1.5 pts. wt. leveling agent, 0.5-1 pts. wt. water repellent, 0.5-1 pts. wt. dispersant, 0.5-1 pts. wt. antifoaming agent, 0.2-0.6 pts. wt. wetting agent and 10-30 pts. wt. deionized water. The graphene-organosilicon-modified aqueous polyurethane resin is obtained from polyisocyanate, polyhydric alcohols, polyamine chain extenders, oligomeric polyols, dimethylol propionic acid and silicone. USE - Graphene-organosilicon modified polyurethane aqueous coating used for protection of cement concrete, metal, wood and other structures. ADVANTAGE - The graphene-organosilicon modified polyurethane aqueous coating has a high cross-linking density, high hardness, good mechanical performance, good waterproof performance, corrosion resistance, antistatic property, high temperature resistance, aging resistance and chemical resistance.
