Problems solved by technology

CN102234419 discloses a halogen-free flame-retardant polyphenylene ether resin composition and its preparation method. Glass fiber is used to reinforce polyphenylene ether, and glass fiber is used to improve mechanical properties and heat resistance, but glass fiber must be added at the fiber port of the extruder Adding more glass fiber, the process is more complicated, and the compatibility of glass fiber and polyphenylene ether is poor, so a large amount of compatibilizer needs to be added, resulting in high processing costs. The density of thermoplastic polyimide is lower than that of glass fiber, which is beneficial Lightweight Development Trend of Polyphenylene Ether Materials

Abstract

The invention discloses a halogen-free flame-retardant high-temperature-resistant polyphenyl ether alloy material and a preparation method thereof. The halogen-free flame-retardant high-temperature-resistance polyphenyl ether alloy material is prepared from the following ingredients in mass fraction: 40 to 60 parts of polyphenyl ether, 10 to 20 parts of polystyrene, 10 to 20 parts of flexibilizer,5 to 10 parts of compound flame retardant, 6 to 15 parts of thermoplastic polyimide, 2 to 5 parts of compatilizer and 0.3 part of antioxidant. According to the halogen-free flame-retardant high-temperature-resistant polyphenyl ether alloy material disclosed by the invention, processability and shock resistance are improved based on ensuring high mechanical property of polyphenyl ether, the halogen-free flame-retardant characteristic is achieved, and high temperature resistance of the alloy material is improved. The halogen-free flame-retardant high-temperature-resistance polyphenyl ether alloy material has wide application in the fields of electrical and electronical, communication photovoltaic and the like.

Description

technical field [0001] The invention relates to a halogen-free flame-retardant high-temperature-resistant polyphenylene ether alloy material and a preparation method thereof, belonging to the technical field of polymer alloy material processing. Background technique [0002] Polyphenylene ether resin (PPE or PPO for short) is one of the five general-purpose plastics, an amorphous thermoplastic resin with excellent properties such as electrical insulation, heat resistance, mechanical properties, flame retardancy and chemical stability. Its products are widely used in electrical and electronic, office equipment, auto parts, chemical industry and other fields. [0003] However, polyphenylene ether has disadvantages such as poor melt fluidity, difficult molding and processing, sensitivity to gaps, easy cracking, and insufficient high temperature resistance. Usually, PPE and PS / HIPS are blended or copolymerized to improve melt fluidity and improve processing. Performance, but al...
