Abstract

The invention discloses a highlight AS / PA9T composite material with an electromagnetic shielding function and a preparation method thereof. The highlight AS / PA9T composite material is characterized bybeing prepared from the following raw materials in parts by weight: 0.5 to 2.5 parts of graphene, 0.5 to 2.5 parts of carbon nanofiber, 3 parts of dispersant, 100 parts of N-methyl pyrrolidone, 47.84to 49.92 parts of terephthalic acid, 44.16 to 46.08 parts of nonanediamine and 30 parts of AS pure resin. The preparation method comprises the following steps: compounding graphene and carbon nanofibers, adding the dispersant, and performing grinding to obtain a nanocarbon material complex; carrying out ultrasonically oscillating and dispersing in N-methyl pyrrolidone, respectively adding terephthalic acid and nonanediamine, stirring at a high speed, and carrying out in-situ polymerization reaction to obtain a composite material PA9T; and blending the obtained composite material PA9T and AS in a high-speed mixer to obtain the PC / PA9T composite material. The composite material has the advantages of high glossiness, high temperature resistance, friction resistance and radiation resistance.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-gloss AS / PA9T composite material with electromagnetic shielding function and a preparation method thereof. Background technique [0002] PA9T (polyamide 9T) is a polyamide engineering plastic with a melting point of 306°C developed from raw material monomers. Molding material with excellent heat resistance, chemical resistance, and friction resistance. Compared with standard nylon, it still maintains effective strength and toughness at higher temperatures, has extremely high thermal stability, and has a water absorption rate of less than 40% of standard nylon. Its excellent performance makes it widely used in electronic and electrical markets. However, while meeting people's living needs, electromagnetic waves are widely present in people's daily life due to the poor glossiness of the materials used and their lack of electromagnetic shielding function, which has...
