Abstract
The invention provides a fatigue-resistant flame-retardant PC/ABS alloy and a preparation method thereof.The alloy is mainly prepared from PC resin, ABS, a flame retardant, a flexibilizer and an anti-dripping agent, the PC resin comprises extrusion-grade PC resin and blow-molding-grade PC resin, the extrusion-grade PC resin and the blow-molding-grade PC resin are large in molecular weight and long in molecular chain, more molecular chain entanglement points are formed, and the anti-dripping agent is added into the extrusion-grade PC resin and the blow-molding-grade PC resin; under the action of external force, the molecular chain is not easy to damage, so that higher fatigue resistance is provided; the flame-retardant PC/ABS alloy material has the advantages that extrusion-grade and blow-molding-grade PC resin is poor in processability, but ABS is excellent in flowability, the phosphorus flame retardant is a plasticizing flow modifier and can make up the defect of poor flowability of the extrusion-grade and blow-molding-grade PC together with ABS, and the flame-retardant PC/ABS alloy material obtained by blending and modifying PC, ABS and the flame retardant has excellent flame retardancy and also has excellent flame retardancy. Moreover, high fatigue resistance is embodied, and meanwhile, the processing fluidity requirement can be met.
Description
technical field [0001] The invention relates to the technical field of chemical synthesis, in particular to a fatigue-resistant flame-retardant PC / ABS alloy and a preparation method thereof. Background technique [0002] Polycarbonate (referred to as PC), has excellent mechanical properties, optical properties and flame retardancy, and is widely used in construction materials, automobiles, electronic appliances, optics, office supplies, medical equipment, aerospace and packaging and other fields. Polycarbonate has the characteristics of excellent impact resistance, high transparency, high strength, creep resistance, good heat resistance, dimensional stability, etc., but due to the high rigidity of the PC molecular chain, its melt viscosity is large, and its fatigue resistance is low. Poor, prone to stress cracking. ABS is a terpolymer of acrylonitrile, butadiene and styrene. It has excellent processability, strong tinting strength, good surface gloss, good dimensional stabi...
