The present invention relates to a gas storage tank, for storing gas, especially CNG, methane and/or hydrogen, said tank comprising a liner comprising a high-viscosity polyamide composition comprising a branched polyamide and an impact modifier, and to a process for manufacturing said the tank. More particularly, the composition comprises a copolyamide of the random tree type resulting from the reaction between a multifunctional monomer comprising at least three reactive functions to form an amide function, these functions being of two different types, difunctional monomers conventionally used in the manufacture of linear polyamides, and optionally difunctional monomers.
本发明涉及一种储气罐,用于储存气体,特别是压缩天然气、甲烷和/或氢气,所述储气罐包括一个内衬,该内衬由一种高粘度聚酰胺组合物组成,该组合物包括一种支化聚酰胺和一种抗冲改性剂,本发明还涉及一种制造所述储气罐的工艺。更具体地说,该组合物包括一种无规树型共聚酰胺,由包含至少三个反应官能团的多官能团单体反应生成酰胺官能团,这些官能团有两种不同类型,一种是通常用于制造线性聚酰胺的双官能团单体,另一种是可选的双官能团单体。
