Glass fiber-reinforced polyamide 66 resin composition with high tensile strength and method of manufacturing the same

摘要

A glass fiber-reinforced polyamide 66 resin composition with a high tensile strength of 260 MPa or more and a method of manufacturing the same are provided. The method of manufacturing the composition includes that 27.2 to 49% by weight of a polyamide 66 resin, 0.2 to 2% by weight of a dye mixture, 0.2 to 2% by weight of a compatibilizer, 0.1 to 3% by weight of an antioxidant, 0.1 to 3% by weight of a lubricant and 50 to 70% by weight of a glass fiber chopped strand are mixed in a twin screw extruder, the materials are extruded in the form of a strand by an extrusion die, and cooled to obtain a pellet-type glass fiber-reinforced polyamide 66 resin composition. The glass fiber-reinforced polyamide 66 resin composition is suitable for vehicular engine mounts due to excellent mechanical strength, and for parts requiring physical properties.
