Description
Technical Field
The invention relates to the technical field of insulating films, in particular to a polyphenyl ether composition and a preparation method and application thereof.
Background
Polyphenylene Oxide is a high-strength engineering plastic developed in the last 60 years, and has a chemical name of poly (2, 6-dimethyl-1, 4-phenylene Oxide), abbreviated as PPO (Polyphenylene Oxide) or PPE (Polyphenylene ether), which is also called Polyphenylene Oxide or Polyphenylene ether. Polyphenylene oxide has good electrical insulation, dimensional stability, low density and heat resistance, and is widely applied to the fields of electronic and electric appliances, automobiles, machinery, chemical engineering and the like. However, in recent years, developments in some fields have made it more desirable to develop materials with higher properties, especially heat resistance and resistance to thermo-oxidative aging, because many application scenarios in this field require long-term exposure to high temperature, and when heat resistance is insufficient, the materials are prone to structural changes due to oxidation and thus to deterioration of mechanical properties.
In addition, the polyphenyl ether has poor flame retardant property, and the polyphenyl ether modified material with high flame retardant property is obtained by adding a flame retardant such as a halogen-free flame retardant in the prior art. However, the halogen-free flame retardant also affects the mechanical properties of the material, and particularly, the commonly used phosphate flame retardant also can obviously reduce the heat and oxygen aging resistance of the material, because the phosphate flame retardant is easy to react with polyphenyl ether under the condition of heat and oxygen, the aging of the material performance is accelerated. This results in the difficulty of simultaneously satisfying high flame retardancy, high mechanical strength and thermo-oxidative aging resistance of polyphenylene ether materials, and thus the application thereof is limited.
Therefore, it is necessary to provide a modified or compounded polyphenylene ether resin material to satisfy both high temperature resistance and flame retardancy requirements.
In view of the above, the present invention is particularly proposed.
