Abstract

The invention discloses a PPO / PA alloy material suitable for wall thinning and a preparation method thereof. The PPO / PA alloy material is composed of following six components in parts by weight: 10 to60 parts of PPO resin, 20 to 70 parts of PA resin, 3 to 10 parts of compatilizer, 5 to 15 parts of flexibilizer, 1 to 5 parts of flow modifier, and 0.1 to 1 part of antioxidant. The alloy material has the advantages that the flow modifier greatly improves the flowing performance of the alloy material, and the modified material can be used to prepare large size thin wall parts by injection moulding.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and in particular relates to a PPO / PA alloy material suitable for thinning the wall and a preparation method thereof. Background technique [0002] Both PPO (polyphenylene ether) resin and PA (nylon) resin are engineering plastics widely used at present. PPO is an amorphous material with excellent heat resistance, outstanding mechanical properties and electrical insulation, good dimensional stability, excellent chemical stability, and good creep resistance. It is one of the most important engineering plastics, but its impact resistance is poor. , high melt viscosity and poor processability, greatly limiting its application in certain fields. PA66 resin is a crystalline material with low melt viscosity, good fluidity and easy processing, but it is easy to absorb water, has poor dimensional stability and poor heat resistance. Using PPO and PA blending compatibilization technology can ob...
