Title: GRAPHENE-MODIFIED POLYURETHANE COMPOSITE, POLYURETHANE ADHESIVE PREPARED FROM SAME, METHOD FOR PREPARING ADHESIVE, AND AEROSTAT
Abstract:
The present invention provides a graphene-modified polyurethane composite, a polyurethane adhesive prepared from same, a method for preparing the polyurethane adhesive, and an aerostat having the polyurethane adhesive. The composite comprises, in percentage by weight: a component A: 10-85%; a component B: 10-85%; a diluent: 1-30%; and modified graphene: 1-5%, wherein the modified graphene is toluene diisocyanate surface-modified graphene oxide or toluene diisocyanate surface-modified graphene. A toluene diisocyanate group in the modified graphene in the composite enables the surface of graphene oxide or graphene to become hydrophobic from hydrophilic, so that the graphene oxide or graphene can be stably dispersed in a diluent, thus being fully dispersed when mixing with the component A and the component B, thereby ensuring uniform dispersion of graphene oxide or graphene in the formed composite.
