Abstract

The invention discloses a graphene-coordinated continuous glass fiber reinforced halogen-free flame-retardant and weather-resistant PPO / HIPS alloy material. The material is prepared from the following components in parts by weight: PPO: 360-480 parts, HIPS: 240-320 parts parts, continuous glass fiber: 200-400 parts, graphene 5-15 parts, compatibilizer 10-20 parts, toughening agent 50-80 parts, flame retardant 80-120 parts, antioxidant 6-10 parts, 3-5 parts of composite light stabilizer, 4-8 parts of lubricant, metal oxide: 5-15 parts. In the present invention, the PPO / HIPS alloy is reinforced by adding pre-dispersed graphene in coordination with continuous glass fiber, and compounding various functional additives, so that the material not only has excellent rigidity and impact toughness, but also has excellent weather resistance and flame retardant. It can meet the application of glass fiber reinforced PPO / HIPS alloy in different fields. The material can be directly molded by injection molding, and the production efficiency is high. The used parts can be recycled after being crushed. .

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...
