▎ 摘　　要

NOVELTY - Preparing graphene aerogel fiber composite plastic honeycomb board involves connecting the bottom plate to the lower surface of the plastic honeycomb panel (3). The graphene aerogel fiber is filled into the cavity of the plastic honeycomb panel. The panel (1) is connected to the upper surface of the plastic honeycomb panel, and released pressure and solidified to obtain a composite board. The periphery of the composite board is sealed with an inorganic heat insulating material to obtain a graphene aerogel fiber (4) composite plastic honeycomb panel. The bottom plate (5), the panel and the inorganic thermal insulation material (6) form a sealed whole. USE - Method for preparing graphene aerogel fiber composite plastic honeycomb board. ADVANTAGE - The method enables to prepare graphene aerogel fiber composite plastic honeycomb board, that has excellent mechanical properties and fire resistance and high temperature resistance. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of preparing graphene aerogel fiber composite plastic honeycomb board.
