Problems solved by technology

[0003] Although there are many types of modified PPO, they still cannot meet the needs of different fields. For example, solar cell junction boxes require materials with high fluidity, good rigidity, good low-temperature toughness, good flame retardancy, excellent insulation performance, and weather resistance. Good and other characteristics, but the current modified PPO materials are difficult to meet the performance requirements of such products

Description

technical field [0001] The invention relates to a polyphenylene ether composition used in a solar cell junction box, in particular to a halogen-free flame-retardant polyphenylene ether composition with improved fluidity and toughness, and belongs to the field of polymer alloys. Background technique [0002] Pure polyphenylene ether (PPO) resin has good mechanical properties, electrical properties, heat resistance, flame retardancy and chemical stability, etc., but its melt viscosity is high, and its processability is extremely poor. Unmodified PPO resin It cannot be molded by injection method, which greatly limits its application. Both PPO and PS are amorphous polymers with very good compatibility and can form alloys in a wide range of blending ratios. However, due to the high rigidity of the PPO molecular chain, it is very sensitive to the notched impact strength, so HIPS can be used to improve its notched impact strength. However, the effect of simply adding HIPS to toug...
