Integrated manufacturing of REciclable multi-material COmposites for the TRANSport sector

Disclosed in the present invention are a polyamide composition having high performance and high-temperature resistance, a preparation method therefor, and the use thereof. The polyamide composition consists of the following raw materials in parts by weight: 21-84.99% of polyamide resin having high-temperature resistance, 5-20% of hyperbranched aromatic-aliphatic copolymerized polyamide, 10-50% of a reinforcer, 0.01-5% of a crosslinker, 0-1% of an antioxidant, 0-2% of a processing aid, and 0-1% of a color masterbatch. During an impregnation process, the crosslinker in the formula can realize the crosslinking of the polyamide resin having high-temperature resistance and the hyperbranched aromatic-aliphatic copolymerized polyamide by means of chemical bonds, thereby avoiding the influence of the hyperbranched aromatic-aliphatic copolymerized polyamide on the heat deformation temperature (HDT) of the polyamide composition having high-temperature resistance. Said polyamide composition prepared by the present invention exhibits excellent mechanical properties and thermal properties, is an ideal material for "plastics replacing steel", and can be applied in the fields of automobiles, smart home, photovoltaics, etc.
