Description
Technical Field
The invention relates to the technical field of composite materials, in particular to a polyphenylene ether-based polymer composite material and a preparation method and application thereof.
Background
With the popularization of 5G technology, the requirements for materials are changed newly after the investment cycle of 5G technology construction is expanded worldwide. The frequency band of 5G is far higher than 4G, and the related material requires lower dielectric constant and loss tangent value at the working frequency and has enough mechanical strength. Specifically, in terms of electrical properties, low loss and low leakage current are required; in the aspect of mechanical property, certain toughness and high hardness are required, otherwise, external force can easily cross the yield strength of the material, and the operation of the component is damaged; in terms of chemical properties, it is required to be resistant to corrosion and have low water absorption; in terms of thermal properties, high stability and low shrinkage are desired. In addition, since the 5G coverage is smaller, the construction density is higher, and the material cost is expected to be lower.
The polyphenyl ether has good comprehensive performance, can be used in steam at 120 ℃, has good electrical insulation and small water absorption, but has stress cracking tendency, and the modified polyphenyl ether can eliminate the stress cracking. The polyphenyl ether has outstanding electrical insulation and water resistance, better wear resistance and electrical property and good dimensional stability, and the dielectric property of the polyphenyl ether is the first place of plastics. The polyphenyl ether is non-toxic, transparent, small in relative density, and has excellent mechanical strength, stress relaxation resistance, creep resistance, heat resistance, water vapor resistance and dimensional stability. The electrical property is good in a wide temperature and frequency range, the main defects are poor melt fluidity and difficult processing and forming, most of the practical application is modified polyphenyl ether (polyphenyl ether blend or alloy), such as the polyphenyl ether modified by polyethylene benzene, the processing property can be greatly improved, the stress cracking resistance and the impact resistance can be improved, the cost is reduced, and the heat resistance and the gloss are slightly reduced. The modified polymer includes polystyrene, polyamide, polytetrafluoroethylene, polytetramethylene terephthalate, polyphenylene sulfide, various elastomers, and the like.
The currently produced polyphenylene ether-based engineering plastics generally cannot give consideration to both strength and toughness, are difficult to process and easy to crack, and generally, polyester-based engineering plastics with high strength have poorer toughness, while polyester-based engineering plastics with good toughness have poorer strength. In many application scenarios, the polyphenylene ether-based engineering plastic is required to have good strength and a certain toughness to meet the use standard. For example, the existing part of polyphenylene ether-based engineering plastics have good toughness but the strength is less than 70MPa, and the strength required by part of use scenes is more than 80MPa, so the strength of the polyphenylene ether-based engineering plastics cannot meet the requirement. Therefore, the existing polyphenylene ether-based engineering plastic needs to be improved, the processability of the polyphenylene ether-based engineering plastic is improved on the basis of not influencing the original excellent dielectric property, and the polyphenylene ether-based engineering plastic with high strength and certain toughness is obtained by adding the modified polymer.
