Abstract

The invention is applicable to the technical field of plastics and provides a PPO / PA66 (poly phenylene oxide / polyamide 66) alloy material as well as a preparation method and application thereof. The PPO / PA66 alloy material comprises the following components in percentage by weight: 15-45% of polyphenyl ether, 15-45% of polyamide 66, 10-30% of carbon fiber, 5-15% of carbon black, 5-10% of compatibilizer, 5-10% of toughening agent, 0.2-0.4% of antioxidant and 0.5-1% of lubricating agent and heat stabilizer. The PPO / PA66 alloy material provided by the invention takes polyphenyl ether and polyamide 66 as basic resins, and the carbon fiber and the carbon black are doped, thus the strength of the PPO / PA66 alloy material is greatly improved; and the antistatic performance of the alloy material is obviously improved. The preparation method of the PPO / PA66 alloy material provided by the invention has low cost and high productivity effect, is simple to operate and is especially applicable to industrialized production.

Description

technical field [0001] The invention belongs to the technical field of plastics, and in particular relates to a PPO / PA66 alloy material, its preparation method and application. Background technique [0002] PPO (polyphenylene ether) resin and PA66 (nylon 66) resin are one of the widely used engineering plastics. PPO is an amorphous material with high heat resistance, stable size and excellent electrical insulation. Resistant to organic solvents. PA66 is a crystalline material with good fluidity and resistance to organic solvents, but it is easy to absorb water and has poor dimensional stability. [0003] PPO / PA66 alloy combines the properties of PPO and PA66. With its excellent heat resistance, good processability and sprayability, it is widely used in automobile door panels, spoilers, wheel covers, electronic housings, electronic components, etc. , These parts require materials with high strength, high heat resistance, light weight, good dimensional stability, and in some...
