Document Type and Number:
WIPO Patent Application WO/2023/071794
Kind Code:
A1
Abstract:
A polycarbonate alloy material, comprising the following components in parts by weight: 40-70 parts of polycarbonate; 20-40 parts of polyethylene terephthalate; and 0.1-2 parts of a metal compound. The metal compound is selected from any one of a metal oxide, a metal base, or a metal salt, and the metal is selected from any one of copper, iron, magnesium, calcium, titanium, antimony, sodium, or potassium. A certain amount of polyethylene terephthalate and a specific metal compound are added to the polycarbonate, such that a prepared polycarbonate alloy material has excellent chemical resistance, also has high melt strength and low melt cooling rate, and is applicable to extrusion blow molding processing to prepare a thick-walled and large-scale packaging container product, such that novel options of materials and molding approaches are provided for the field of packaging, the use requirements of drug packaging containers can be particularly satisfied, and the application of a polycarbonate material is further broadened.
