Summary: | The invention belongs to the technical field of adhesives, and particularly relates to a self-complementary quadruple hydrogen bond supramolecular hot melt adhesive and a synthesis method thereof, and the supramolecular hot melt adhesive is synthesized from the following raw materials in parts by mole: 1.0 part of macromolecular polyol, 2.0-2.8 parts of aromatic diisocyanate and 2.0-3.6 parts of pyrimidone derivative. A rigid benzene ring and a ureido pyrimidone element (UPy) containing self-complementary quadruple hydrogen bonds are introduced to the tail end of a macromolecular dihydric alcohol chain, the raw material source is wide, and the synthesis route is simple; the UPy has very high hydrogen bond binding energy, can be used as a non-covalent crosslinking element, is associated at room temperature to obtain high-strength supramolecular resin, and is dissociated at high temperature to endow the supramolecular hot melt adhesive with repeated bonding capacity. The viscous flow temperature of the supramol |
