Graphene aerogel heat-preservation non-combustible plate and preparation method thereof
The invention belongs to the field of graphene materials, and discloses a graphene aerogel heat-preservation non-combustible plate and a preparation method thereof.The graphene aerogel heat-preservation non-combustible plate is prepared by fully dispersing graphene oxide aerogel powder and graphene powder to obtain dispersion liquid, putting the dispersion liquid into a centrifugal spray dryer, heating and drying to obtain mixed powder of graphene and graphene aerogel powder, and sintering the mixed powder to obtain the graphene aerogel heat-preservation non-combustible plate. Adding a foaming agent formed by mixing pentane, polystyrene, cement, reinforced fibers and water glass into the mixed powder of the graphene and the graphene aerogel powder, continuously blowing inert gas to obtain pre-foaming slurry, then introducing the pre-foaming slurry into a pre-foaming barrel, introducing steam for heating, curing, and then extruding, foaming and forming to obtain the graphene/graphene aerogel composite material. The graphene aerogel heat-preservation non-combustible plate produced by the invention has an excellent heat-preservation effect and also has good fireproof performance, and the safety of the heat-preservation plate is improved.
本发明属于石墨烯材料领域，公开了一种石墨烯气凝胶保温不燃板及其制备方法，将氧化石墨烯气凝胶粉末与石墨烯粉体充分分散，得到分散液，将上述分散液放入离心喷雾干燥机，加热干燥得到石墨烯和石墨烯气凝胶粉体混合粉料，在上述石墨烯和石墨烯气凝胶粉体混合粉料内加入戊烷、聚苯乙烯、水泥、增强纤维、水玻璃混合而成的发泡剂，并持续吹入惰性气体，得到预发泡浆料，接着通入预发泡桶，通入蒸汽进行加热，熟化后挤压发泡成型，本发明生产出的石墨烯气凝胶保温不燃板具有优良的保温效果，同时有良好的防火性能，提升保温板的安全性。
