Preparation method of three-in-one heat insulation material taking graphene as heat reflection layer
The invention discloses a preparation method of a three-in-one heat insulation material with graphene as a heat reflection layer, and belongs to the technical field of heat insulation materials. The preparation method of the three-in-one heat insulation material with graphene as the heat reflection layer comprises the following steps: preparing a graphene composite film supported by a carbon fiber fabric; preparing the graphene composite film into a plate felt or a barrel felt; compared with a carbon-carbon composite material winding soft felt, the preparation method disclosed by the invention has the advantages that the structure is simpler and more integrated, the installation is convenient, the disassembly is simple and convenient, two materials are replaced by one material, and the cost of consumables is greatly saved; the graphene film is high in compactness, the barrier property is far better than the effect of a coating, the corrosion resistance is better, and the service life is longer; the in-plane thermal conductivity of the graphene film is high, the soaking effect is more obvious, the interlayer thermal conductivity is far lower than that of graphite, the heat conduction loss is small, a bright reflecting film can be formed under low pressure, and the thermal reflection effect is far better than that of a coating and graphite paper.
本发明公开了一种以石墨烯为热反射层的三合一隔热材料的制备方法，属于隔热材料技术领域；以石墨烯为热反射层的三合一隔热材料的制备方法包括以下步骤：制备带有碳纤维织物支撑的石墨烯复合膜；将石墨烯复合膜制备成板毡或筒毡；本发明的制备方法相比于碳碳复合材料缠绕软毡从结构上更简单，一体化，方便安装，拆卸简便，以一种材料替换了两种材料，大大节约了耗材的成本；石墨烯膜的致密性高，阻隔性远好于涂层的效果，抗侵蚀性更好，使用寿命更长；石墨烯膜的面内导热率高，均热效果更明显，层间导热远低于石墨热传导损失小，在较低的压力下即可形成光亮的反射膜，热反射效果远大于涂层及石墨纸的效果。
