Example Embodiment
[0041] Example 1
[0042] A preparation method of high impact and high CTIPPS composite material includes the following steps:
[0043] (1) Weigh the raw materials according to the amount of PPS, PA66, toughening agent, coupling agent, antioxidant and lubricant in Table 1;
[0044] (2) After mixing PPS and coupling agent at 120°C for 10 minutes, cool to 60°C, then add PA66, toughening agent, antioxidant and lubricant and mix for 5 minutes, then add it to the main feed hopper of the extruder and feed it on the side The glass fiber is added to the hopper, and the pellet is extruded through a twin-screw extruder.
[0045] The speed of the twin screw extruder is 400r / min, and the temperature is 260-300°C. The properties of the resulting high impact and high CTIPPS composites are shown in Table 2.

[0046] Example 2
[0047] A preparation method of high impact and high CTIPPS composite material includes the following steps:
[0048] (1) Weigh the raw materials according to the amount of PPS, PA66, toughening agent, coupling agent, antioxidant and lubricant in Table 1;
[0049] (2) After mixing PPS and coupling agent at 130°C for 9 minutes, cool to 70°C, then add PA66, toughening agent, antioxidant and lubricant to mix for 4 minutes, then add it to the main feed hopper of the extruder and feed it on the side The glass fiber is added to the hopper, and the pellet is extruded through a twin-screw extruder.
[0050] The speed of the twin-screw extruder is 300r / min, and the temperature is 260-300°C. The properties of the resulting high impact and high CTIPPS composites are shown in Table 2.

[0051] Example 3
[0052] A preparation method of high impact and high CTIPPS composite material includes the following steps:
[0053] (1) Weigh the raw materials according to the amount of PPS, PA66, toughening agent, coupling agent, antioxidant and lubricant in Table 1;
[0054] 2) After mixing PPS and coupling agent at 140°C for 8 minutes, cool to 80°C, add PA66, toughening agent, antioxidant and lubricant and mix for 3 minutes, and then add it to the main feed hopper of the extruder, in the side feeding hopper Add glass fiber, extrude and granulate through twin screw extruder.
[0055] The speed of the twin-screw extruder is 500r / min, and the temperature is 260-300°C. The properties of the resulting high impact and high CTIPPS composites are shown in Table 2.
