|1. (WO2018076779) ADHESIVE AND PREPARATION METHOD THEREOF, AND ENVELOPE MATERIAL|
|Applicants:||SHENZHEN KUANG-CHI SPACE TECH. CO., LTD.
|Title:||ADHESIVE AND PREPARATION METHOD THEREOF, AND ENVELOPE MATERIAL|
An adhesive comprises an adhesive body and graphene. The weight percentage of graphene in the adhesive is 0.2-1%. Graphene is added in the adhesive body so that graphene is dispersed in the adhesive body. Graphene has a good helium blocking performance, and therefore, the adhesive comprising same also has a helium blocking performance. Moreover, graphene is low in amount, i.e., between 0.2% and 1%, and therefore, the surface density of the envelope material would not be increased significantly, which is of great significance to lightweight of the airship envelope material. Furthermore, graphene is added in the adhesive, and therefore, the processing complexity of the envelope material would not be increased.
