Abstract

The invention relates to a low VOC high-performance PET-PS composite material and a preparation method thereof. The preparation method comprises the following steps: weighting 80-100 parts of PPE, 20-30 parts of PS, 2-6 parts of PPE-g-PS, 10-20 parts of modified basalt fiber and 0.1-0.5 part of antioxidant in parts by weight, mixing and uniformly stirring, thereby acquiring a mixture, and then adopting a twin-screw extruder for extruding and pelletizing the acquired mixture, thereby acquiring the PET-PS composite material. According to the technical scheme, the low VOC high-performance PET-PScomposite material is prepared by introducing nanometer TiO2 and improving the basalt fiber VOC under a photocatalytic condition; a rare earth element acts on the surface of the basalt fiber, so thatmore oxygen-containing active groups are attached to the fiber surface; as an intermediate, the rare earth element is capable of boosting the chemical bond connection between the surface of the basaltfiber and the PPE material, so that the mechanical property of the composite material can be promoted.

Description

technical field

[0001] The invention belongs to the technical field of polymer materials, in particular to a low-VOC high-performance PPE-PS composite material and a preparation method thereof. Background technique

[0002] Polyphenylene ether (PPE) and polystyrene (PS) are two widely used resins. It is of great significance if the two can be blended and modified to complement each other in performance. For the PPE-PS blend system, the compatibility of the two is relatively poor, which seriously affects the physical properties of the PPE-PS composite material.

[0003] This technical solution has innovatively prepared a low-VOC high-performance PPE-PS composite material, and the relevant literature has not been reported. This has very important practical significance for expanding the application range of PPE-PS composite materials. Contents of the invention

[0004] The purpose of the present invention is to provide a low-VOC high-performance PPE-PS composite material an...
