[0046] As another aspect of the embodiment of the present invention. The embodiment of the present invention also provides a preparation method of the polyphenylene ether / polyamide alloy material of the embodiment of the present invention described above. In one embodiment, the preparation method of the polyphenylene ether / polyamide alloy material in the embodiment of the present invention includes the following steps:
[0047] Step S01. Weighing the raw materials of each component: Weighing the raw materials of each component according to the components and contents contained in the polyphenylene ether / polyamide alloy material according to the embodiment of the present invention;
[0048] Step S02. Perform mixing treatment on the weighed part of the component raw materials: perform mixing treatment on the functional masterbatch, elastomer, graft, flame retardant, and antioxidant weighed in step S01 to form a mixed material ;
[0049] Step S03. Carrying out melt-extrusion tr...
Embodiment 1
[0061] Embodiments of the present invention provide a polyphenylene ether / polyamide alloy material and a preparation method thereof.
[0062] The polyphenylene ether / polyamide alloy material contained the components shown in Example 1 in Table 1 below.
[0063] The preparation method is: add 50 parts of polyphenylene ether resin from the first weight loss feeding port, 30 parts of polyamide resin, 5 parts of polystyrene resin, 4 parts of functional masterbatch, 7 parts of elastomer, 4 parts of graft , 8 parts of flame retardant, and 0.3 parts of antioxidant are added from the second weight loss feeder after high mixing, and then plasticized, melted, extruded, drawn, cooled, and pelletized through a twin-screw extruder. The pellets were dried in a blower oven at 120°C for 2-4 hours, and then injection-molded to prepare test specimens and products.
