Abstract

The invention relates to an anti-aging high-performance PET composite material and a preparation method thereof. The PET composite material is prepared from the following components in parts by weight: 80 to 100 parts of PET, 10 to 20 parts of treated fiber powder and 0.1 to 0.5 part of an antioxidant. According to the technical scheme, basalt fibers are ground into fiber powder through a physical method, the fiber powder loaded with rare earth ions and TiO2 is finally prepared, and compared with commercially available fibers, the fiber powder loaded with rare earth ions and TiO2 is more excellent in mechanical property and better in aging property when being used for modifying PET.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to an anti-aging high-performance PET composite material and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET) is a widely used polymer polyester resin, PET has good fatigue resistance, good heat resistance, excellent dimensional stability and other advantages, but PET's The anti-aging performance is general, which limits the application of PET composite materials in some specific fields. Contents of the invention [0003] The purpose of the present invention is to provide an anti-aging high-performance PET composite material and its preparation method to solve the problem that the existing PET composite material has poor anti-aging performance and affects the application field of the PET composite material. [0004] In order to achieve the above object, the application is achieved through the following technical so...
