Description

technical field [0001] The invention belongs to the technical field of material modification, and in particular relates to a deformation-resistant high-performance flame-retardant reinforced PET modified engineering plastic and a preparation method thereof. Background technique [0002] PET material was first industrially produced by DuPont in 1953. It is a crystalline high polymer with a high melting temperature and a high glass transition temperature. PET material maintains good physical properties in a wide temperature range, has excellent fatigue resistance, friction resistance, aging resistance, insulation resistance, etc., and is stable in solvent resistance and acid resistance, so it is widely used in capacitor shells, Low-voltage electrical enclosures, connectors and transformer bobbins, coil tray supports, etc. [0003] Due to the slow crystallization speed of glass fiber reinforced PET modified engineering plastics, higher molding temperature and molding cycle are...
