Abstract

The invention relates to a glass fiber reinforced poly(ethylene terephthalate)/polycarbonate alloy and a preparation method thereof. The alloy has the innovation point that the glass fiber reinforced poly(ethylene terephthalate)/polycarbonate alloy is prepared by employing a liquid-phase chemical deposition method to cover a rare earth compound layer on surfaces of glass fiber and glass microspheres, and processing with poly(ethylene terephthalate), polycarbonate, a flexibilizer, a nucleating agent and an anti-oxidant in a melt blending manner by a double-screw extrusion machine. The alloy can be subjected to injection molding at a mold temperature of 60 DEG C, has the characteristics of being low in warping property, free of micromolecule volatile matter during spraying, excellent in mechanical properties, high in thermal deformation temperature, stable in dimension and the like, and is applicable to injection molding of vehicle doors, wind shields, tyre guard boards and even whole vehicle bodies.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a glass fiber reinforced polyethylene terephthalate / polycarbonate alloy. Background technique [0002] Automobile plasticization is the development trend of automobile lightweight. Automobile body panels are one of the heaviest parts in automobiles, and the plasticization of body panels is of great significance for reducing the weight of the vehicle. The currently developed body plastic sheets are mainly made of glass fiber reinforced polyethylene terephthalate (PET), and the applied parts include front and rear covers, doors, vertical panels of the body, windshields, tire guards and even the entire body. [0003] Glass fiber reinforced PET materials have excellent mechanical properties, electrical insulation properties, chemical corrosion resistance and aging resistance. During the injection molding process of glass fiber reinforced PET materials, due to the orientation of gla...
