Abstract

The invention discloses a graphene coordinated continuous glass fiber reinforced halogen-free flame-retardant weather-resistant PPO/HIPS alloy material. The material is prepared from the following components in parts by weight: 360 to 480 parts of PPO, 240 to 320 parts of HIPS, 200 to 400 parts of continuous glass fiber, 5 to 15 parts of graphene, 10 to 20 parts of a compatibilizing agent, 50 to 80 parts of a toughening agent, 80 to 120 parts of a flame retardant, 6 to 10 parts of an antioxidant, 3 to 5 parts of a composite light stabilizer, 4 to 8 parts of a lubricant and 5 to 15 parts of metal oxide. According to the invention, through addition of predispersed graphene coordinated continuous glass fiber reinforced PPO/HIPS alloy, and compounding with a variety of functional additives, the material provided by the invention has excellent rigidity, impact toughness, weather resistance and flame-retardant performance; meanwhile, no glass fiber is exposed on the surface of an injection-molded workpiece, so application of glass fiber reinforced PPO/HIPS alloy in different fields can be satisfied; the material can be directly molded through injection molding, so the production efficiency is high; and a used workpiece can be recycled after crushing.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a graphene synergistic continuous glass fiber reinforced halogen-free flame-retardant and weather-resistant PPO / HIPS alloy material and a preparation method thereof. Background technique [0002] Polyphenylene oxide (PPO) is an excellent thermoplastic engineering plastic. It has good mechanical properties, thermal properties and electrical properties, but has the disadvantages of high melting temperature, high melt viscosity, poor thermoplastic formability and poor resistance to organic solvents (such as halogenated aliphatic hydrocarbons), which limit its application range. In order to improve the performance of PPO and expand its application field, it is necessary to modify PPO, and the modified PPO is called MPPO. The modified polyphenylene ether alloy has excellent comprehensive performance and many varieties, and is widely used in various fields, such as: automobi...
