▎ 摘　　要

NOVELTY - Method for preparing a low thermal conductivity hydrophobic melamine foam involves (i) impregnating melamine foam in a graphene oxide aqueous solution, repeatedly extruding for multiple times and leaving still and (ii) taking out the melamine foam in step (i) and performing thermal reduction after vacuum drying. USE - The method is useful for preparing a low thermal conductivity hydrophobic melamine foam. ADVANTAGE - The method can reduce the thermal conductivity of the melamine foam while endowing with hydrophobic properties, adopts simple and easy operation process, is convenient for industrialization and avoids technical problems such as difficulty in foaming and low foaming effect due to the addition of other additives before foaming. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the low thermal conductivity hydrophobic melamine foam prepared by the method.
