▎ 摘 要
NOVELTY - Hot melt adhesive comprises 10-65 pts. wt. polyester polyol, 20-55 pts. wt. polyether polyol, 0.1-20 pts. wt. graphene, 5-30 pts. wt. isocyanate and 0.0001-0.001 pts. wt. catalyst. USE - The hot melt adhesive is useful for conducting polyurethane (claimed). ADVANTAGE - The hot melt adhesive has high adhesion strength. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the hot melt adhesive, comprising heating the polyester polyol, polyether polyol and graphene, stirring, ultrasonically dispersing for 0.5-10 hours under vacuum until the graphene is uniformly dispersed, adding isocyanate, stirring and reacting for 1-5 hours, vacuuming, adding catalyst when cyanate reaches the theoretical value, vacuum stirring for 30 minutes, pouring out the product under nitrogen protection, then sealing and packaging.
