Non-antimonide halogen-free flame-retardant polyamide composite material and preparation method thereof

[0051] According to the comparative example 1 ~ 2 described in table 1 and specific embodiment 1 ~ 8 formula consumption, weigh each component respectively, and above-mentioned each component is dropped in the mixer and mixes until uniform, obtains premix; Then The obtained premix is ​​put into a twin-screw extruder for melting and mixing, and extruded and granulated to obtain a PA66 / PPS alloy material; wherein the screw length-to-diameter ratio of the twin-screw extruder is 40~48:1, and the barrel temperature is 270~300℃, the screw speed is 300~450rpm. The composite material that above-mentioned each embodiment and comparative example are made is injection-molded into the standard sample that tests are used earlier by standard size, then carries out each performance test according to test standard; The performance test data of each example sample is shown in Table 2:
