Abstract

The invention relates to a self-repairing carbon fiber reinforced polyphenylene sulfide composition. The self-repairing carbon fiber reinforced polyphenylene sulfide composition comprises, by weight,65 to 90 parts of PPS resin, 10 to 30 parts of carbon fiber, 1 to 3 parts of allyl mercaptan, 2 to 5 parts of nanometer silver, 0.1 to 1 part of an anti-oxidant, and 0.1 to 1 part of a lubricant. A preparation method comprises following steps: PPS resin, the anti-oxidant, and the lubricant are mixed, and are introduced into an extrusion machine through a main feed inlet; carbon fiber is introducedinto the extrusion machine through a first side feed inlet of an extrusion machine cylinder body; allyl mercaptan and nanometer silver is introduced into the extrusion machine through a second side feed inlet of the extrusion machine cylinder body; and extrusion machine blending granulation is carried out so as to obtain the self-repairing carbon fiber reinforced polyphenylene sulfide composition. Compared with the prior art, the advantages are that: the repairing performance is excellent, the service life is long, the mechanical performance is excellent, the self-repairing carbon fiber reinforced polyphenylene sulfide composition can be used for preparing high strength high toughness materials, and the application prospect is promising.

Description

Technical field[0001]The invention relates to the field of polymer materials, in particular to a self-repairing carbon fiber reinforced polyphenylene sulfide composition and a preparation method thereof.Background technique[0002]Polyphenylene sulfide is widely used in the automotive and electronic industries due to its excellent heat resistance, fluidity, flame resistance and electrical properties. Carbon fiber reinforced polyphenylene sulfide has ultra-high rigidity, which can replace metal, has low density, strong rigidity and convenient processing.[0003]However, high-molecular materials, especially high-rigidity polymers, such as carbon fiber reinforced polyphenylene sulfide, once cracks occur, irreversible damage occurs, causing the cracks to continue to grow, and finally the material fails.[0004]At present, the main methods for constructing self-healing polymer materials are: one is to embed the repair agent in the polymer material substrate, the typical system is microcapsule ...
