Abstract

The invention relates to a PET (polyethylene terephthalate) composite material and a preparation method thereof. The PET composite material is prepared from the following components in parts by weight: 70-90 parts of PET, 10-16 parts of modified jute fiber, 10-16 parts of nano feldspar powder, 10-14 parts of toughening agent and 0.1-0.5 part of antioxidant. A rare earth element acts on the surfaceof the jute fiber so that more oxygen-containing active groups are adhered to the fiber surface; as an intermediate medium, the rare earth element promotes chemical bond connection between the jute fiber surface and the PET material and enhances the mechanical property of the rare earth element; the PET material provided by the invention is improved to a certain degree in tensile strength, impactstrength, flexural modulus and hardness in comparison with that before modification.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a PET composite material and a preparation method thereof. Background technique [0002] Polyethylene terephthalate (PET) is a common high-molecular polyester resin. It has good chemical properties and solvent resistance, but at the same time it also has a small notched impact strength, which is easy to appear break phenomenon. [0003] In response to this situation, the application innovatively uses jute fiber and nano-feldspar powder to modify PET, and finally makes a high-performance and environmentally friendly PET composite material. This material has not been seen in reports so far, which has great significance for expanding the application of PET composite materials. very important practical significance. Contents of the invention [0004] The object of the present invention is to provide a PET composite material and a preparation method thereof, so as to sol...
