Problems solved by technology
[0002] Reinforced polyphenylene ether materials have been widely used in water valve spools, high-voltage wrapped coil skeletons, water pump impellers and auto parts. The material is composed of polyphenylene ether raw powder, polystyrene resin, glass fiber and other additives. Due to The bonding between glass fiber and polyphenylene ether raw powder is poor, and the two are easy to separate, resulting in a decrease in the notched impact resistance of the material. Usually, the notched impact resistance of reinforced polyphenylene ether materials is 6-8KJ / m 2 , made into various parts that are brittle and easy to crack

Abstract
The invention discloses a phase solvent suitable for a reinforced polyphenylene oxide material. The phase solvent consists of polyphenylene oxide resin, polystyrene resin, styrene-butadiene rubber, maleic anhydride, and a decolorizing antioxidant. The invention enables effective phase dissolution between polyphenylene oxide raw powder and glass fiber, and makes the polyphenylene oxide raw powder and glass fiber combined together stiffly, so that the notch impact resistance of the reinforced polyphenylene oxide material can be effectively improved, and the notch impact resisting strength of the modified material is enhanced from original 6-8KJ / m<2> to 11-15KJ / m<2>. In addition to be used in a reinforced polyphenylene oxide material, the phase solvent provided in the invention can also be used in flame-retarded and reinforced polyphenylene oxide materials and reinforced polyphenylene oxide materials in inorganic filler.
