Embodiment 1

[0040] 75 parts of polyphenylene ether resin (PPE), 8 parts of hydrogenated styrene-butadiene-styrene (SEBS), 0.2 part of primary antioxidant and 0.2 part of auxiliary antioxidant are fed from the first weight loss type after high mixing 25 parts of polystyrene resin (PS) and 2.5 parts of linear low-density polyethylene (LDPE) are added from the second weight loss feeder after high mixing, and 10 parts of liquid flame retardant are fed from the liquid through a liquid pump It is added at the mouth, and then the twin-screw extruder is plasticized, melted, extruded, drawn, cooled, and pelletized. The pellets were dried in an air blast oven at 110°C for 2 hours, and then test specimens and products were prepared by injection molding machines. The main antioxidant is 3,5-di-tert-butyl-4-hydroxyphenyl propionate stearyl; the auxiliary antioxidant is tris(nonylphenyl)phosphite.

Embodiment 2

[0042] 75 parts of polyphenylene ether resin (PPE), 8 parts of hydrogenated styrene-butadiene-styrene (SEBS), 0.2 part of primary antioxidant and 0.2 part of auxiliary antioxidant are fed from the first weight loss type after high mixing 25 parts of polystyrene resin (PS) and 5 parts of linear low-density polyethylene (LDPE) are added from the second weight loss feeder after high mixing, and 10 parts of liquid flame retardant are fed from the liquid through a liquid pump It is added at the mouth, and then the twin-screw extruder is plasticized, melted, extruded, drawn, cooled, and pelletized. The pellets were dried in an air blast oven at 110°C for 2 hours, and then test specimens and products were prepared by injection molding machines. The main antioxidant is 3,5-di-tert-butyl-4-hydroxyphenyl propionate stearyl; the auxiliary antioxidant is tris(nonylphenyl)phosphite.

Embodiment 3

[0044] 75 parts of polyphenylene ether resin (PPE), 8 parts of hydrogenated styrene-butadiene-styrene (SEBS), 0.2 part of primary antioxidant and 0.2 part of auxiliary antioxidant are fed from the first weight loss type after high mixing 25 parts of polystyrene resin (PS) and 1 part of silicone masterbatch are added from the second weight loss feeder after high mixing, 10 parts of liquid flame retardant are added from the liquid feeding port through a liquid pump, and then Twin-screw extruder plasticizing, melting, extruding, drawing, cooling, pelletizing. The pellets were dried in an air blast oven at 110°C for 2 hours, and then test specimens and products were prepared by injection molding machines. The main antioxidant is 3,5-di-tert-butyl-4-hydroxyphenyl propionate stearyl; the auxiliary antioxidant is tris(nonylphenyl)phosphite. Silicone masterbatch is dimethyl silicone oil with low density polyethylene as the carrier.

Abstract

The invention discloses a polyphenyl ether resin material used for processing a charger case, which consists of polyphenyl ether resin, polystyrene resin, an elastic body, fire retardants, polyolefin, silicone masterbatch, main antioxidants and auxiliary antioxidants. Through adding proper auxiliary agents into a polyphenyl ether resin composition, the invention improves the surface lubricating effect of manufactured elements, reduces the pressure required during welding, and solves the problems of impression, scratches and the like occurring during the ultrasonic welding of products. The products are mainly applied to the fields requiring the ultrasonic welding, such as charger cases, wiring cases and the like.

Description

Technical field: [0001] The invention relates to a polyphenylene ether resin material used for processing charger shells. Background technique: [0002] The polyphenylene ether resin composition has excellent mechanical properties, electrical resistance, heat resistance, and good dimensional stability, and is widely used in industries such as household appliances and auto parts. These industries require materials with high strength, high toughness, high flame retardancy, high heat resistance, etc., such as charger shells, junction boxes, instrument panels, and automotive air intake components. However, many of these same components are made into multiple parts, and these parts need to be assembled into products according to certain methods to meet the requirements. At present, ultrasonic welding technology is the most widely used to make the products reach the purpose of use. [0003] Ultrasonic welding is a welding method that converts electromagnetic wave energy into heat...
