Abstract

The invention relates to a wear-resistant carbon fiber reinforced nylon 66 resin composition and a preparation method thereof, which mainly solves the problem of low impact strength of the existing wear-resistant carbon fiber reinforced nylon 66 resin composition and the problem that the tensile strength can be lowered after adding an impact modifier. The wear-resistant carbon fiber reinforced nylon 66 resin composition comprises the following components in parts by weight: A 45-70 parts of nylon 66 resin, B 1-20 parts of nylon 6 resin, C 5-25 parts of polytetrafluoroethylene resin, D 10-40 parts of carbon fiber and E 0.01-5 parts of at least one assistant from an antioxidant and a compatilizer. The technical scheme provided by the invention well solves the problem, and can be used for industrial production of injection molding processing of gears, bearings, pulleys, mechanical pump rotors and other mechanical parts.

Description

technical field

[0001] The invention relates to a wear-resistant carbon fiber reinforced nylon 66 resin composition with improved impact strength and a preparation method thereof. Background technique

[0002] In recent years, with the increase of carbon fiber production and price reduction, the application of carbon fiber reinforced thermoplastic resin composite materials has become more and more widespread. For example, US Patent No. 6,231,788 discloses a carbon fiber with electromagnetic shielding properties composed of PC-ABS resin composite and carbon fiber. Composite material, which can be used for dust-proof equipment and notebook computer casing; Chinese patent CN101139462 discloses a flame-retardant carbon fiber composite material composed of polyamide resin, carbon fiber, red phosphorus flame retardant, toughening agent, etc.; Chinese patent CN1165523 discloses A carbon fiber composite material with excellent abrasion resistance composed of ground carbon fiber, pol...
