The invention discloses a polyetheretherketone composition with excellent anti-aging performance and a preparation method thereof. The polyetheretherketone composition is composed of the following components by weight: 100 parts of polyetheretherketone, 10-20 parts of polyetherketone parts, 15-30 parts of glass fiber, 1-5 parts of ethylene bis-stearamide, 0.1-0.3 parts of 4,4'-methylene bis(2,6-di-tert-butylphenol), bis(2,4 -Dicumylphenyl) pentaerythritol diphosphite 0.1-0.3 part. In the present invention, by adding a compound combination of 4,4'-methylene bis(2,6-di-tert-butylphenol) and bis(2,4-dicumylphenyl) pentaerythritol diphosphite, it can be Compared with the oxygen system, its heat aging resistance has been greatly improved. The retention rate of mechanical properties after aging is increased, and the color difference after aging is low. |
