Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a flame-retardant polyphenylene ether / polypropylene alloy material and a preparation method thereof. Background technique [0002] Polyphenylene ether (PPE or PPO for short) is a high-performance thermoplastic engineering plastic with good mechanical properties, chemical stability, dielectric properties, heat resistance and flame retardancy, but the molecular chain of PPO is relatively rigid. Large, notch impact is very sensitive, its high melt viscosity makes it impossible for injection molding and PPO's poor oil resistance and other shortcomings greatly limit its application. However, polypropylene (PP), as a general-purpose plastic, is poor in physical and mechanical properties and heat resistance, but has obvious advantages in processability, oil resistance, acid and alkali corrosion resistance, and cost. At present, the development of flame-retardant polypropylene materials...
