Abstract

The invention relates to a PET composite material, which is composed of the following components by weight: 70-90 parts of PET; 10-16 parts of modified jute fiber; 3-5 parts of polytitanoxane; 10-16 parts of nano-feldspar powder; 10-14 parts of a toughener; and 0.1-0.5 part of an antioxidant. Rare earth elements act on the surface of jute fiber to attach more oxygen-containing active groups to thefiber surface, serving as an intermediate medium, rare earth elements promote the generation of chemical bond connection between the jute fiber surface and PET material, thus improving the mechanicalproperties in itself. The tensile strength, impact strength, bending modulus and hardness of the PET material provided by the invention are all improved to certain degree than those before modification.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular to a PET composite material. 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 purpose of the present invention is to provide a PET composite material to solve the problem of low impact strength of PET materials in the prior art....
