Abstract

The invention discloses a PA66 / PPO composite material and a preparation method thereof. The PA66 / PPO composite material is composed of the following components in parts by weight: 15-25 parts of low-viscosity polyhexamethylene adipamide, 15-25 parts of high-viscosity polyhexamethylene adipamide, 20-35 parts of polyphenylene ether, 1-10 parts of a compatibilizer A, 1-10 parts of a compatibilizer B,1-10 parts of a toughening agent, 1-5 parts of a lubricant A, 0.1-2 parts of a lubricant B, 0.1-1 part of an antioxidant A, 0.1-1 part of an antioxidant B, 2-8 parts of a flame retardant, 0.1-1 partof a heat stabilizer, and 0.2-1 part of a dispersant, wherein the low-viscosity polyhexamethylene adipamide has viscosity of 1.05-1.1Pa*s, and the high-viscosity polyhexamethylene adipamide has viscosity of 2.55-2.85Pa*s. The PA66 / PPO composite material disclosed by the invention has the advantages of high strength, high impact, high heat resistance, difficult flammability, and excellent electrical insulating performance and flame retardance.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a PA66 / PPO composite material and a preparation method thereof. Background technique [0002] Polyphenylene ether (PPO) resin and polyhexamethylene adipamide (PA66) resin are one of the widely used engineering plastics. PPO has high heat resistance, stable size, and good electrical insulation, but its processing fluidity is poor and it is not durable 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. PA66 / PPO synthetic plastic combines the properties of PPO and PA66, and is widely used for its excellent heat resistance, good processability, and sprayability. At present, most reinforced PA66 / PPO synthetic plastics have low strength and poor heat resistance, which limits the application of PA66 / PPO synthetic plastics. Contents of the invention [0...
