| titleOfInvention | Modified polyurethane material |
| abstract | The invention provides a modified polyurethane material which is obtained by reacting diisocyanate compounds with graphene modified by hydroxyl. Compared with the prior art, the hydroxyl modified graphene adopted by the invention has a special structure, the liquid state of the graphene material can be realized by controlling the length and the number of the alkyl hydroxyl chain segments on the graphene sheet layer, enough steric hindrance effect can be provided to limit the irreversible superposition of the graphene sheet layer, the dispersion problem of the modification of the graphene as a nano material is solved, and the hydroxyl modified graphene can be directly used as a polyurethane material A component to react and solidify with diisocyanate compounds, so that the obtained modified polyurethane material not only has excellent damping performance, but also has a very stable internal structure. |
