Embodiment 1
[0024] 70 parts of polyphenylene ether resin (PPE) and 0.5 parts of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) are mixed and added from the first weight loss feeder , 30 parts of high-impact polystyrene resin (HIPS) is added from the second loss-in-weight feeder, plasticized, melted, extruded, drawn, cooled, pelletized, extruded and injected through a twin-screw extruder The temperature is between 250-320°C. The pellets were dried at 110°C for 2 h in a blast drying oven, and then test specimens were prepared by injection molding machine. At the same time, part of the pellets were taken according to the previous steps to back-extrude, granulate, and dry through the twin-screws, and the test specimens were also prepared by the injection molding machine.
Embodiment 2
[0028] 70 parts of polyphenylene ether resin (PPE), 6 parts of hydrogenated styrene-butadiene-styrene (SEBS), 0.5 parts of 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxid After high mixing, DOPO is added from the first loss-in-weight feeder, and 30 parts of high-impact polystyrene resin (HIPS) is added from the second loss-in-weight feeder, and then the twin-screw extruder is plasticized, Melting, extrusion, drawing, cooling, pelletizing, extrusion and injection molding temperature are between 250-320 ℃. The pellets were dried at 110°C for 2 h in a blast drying oven, and then test specimens were prepared by injection molding machine. At the same time, part of the pellets were taken according to the previous steps to back-extrude, granulate, and dry through the twin-screws, and the test specimens were also prepared by the injection molding machine.
Embodiment 3
[0031] Example 3: 70 parts of polyphenylene ether resin (PPE), 8 parts of hydrogenated styrene-butadiene-styrene (SEBS), 0.5 part of 9,10-dihydro-9-oxa-10-phosphaphenanthrene -10-Oxide (DOPO) is added from the first loss-in-weight feeder after high-mixing, 30 parts of high-impact polystyrene resin (HIPS) is added from the second loss-in-weight feeder, and 8 parts of liquid flame retardant The agent is added from the liquid feed port through a liquid pump, and then the twin-screw extruder is plasticized, melted, extruded, drawn, cooled, and pelletized. The extrusion and injection molding temperatures are between 250-320°C. The pellets were dried at 110°C for 2 h in a blast drying oven, and then test specimens were prepared by injection molding machine. At the same time, part of the pellets were taken according to the previous steps to back-extrude, granulate, and dry through the twin-screws, and the test specimens were also prepared by the injection molding machine.
