The invention discloses a PPS (polyphenylene sulfide) composite material and a preparation method thereof. The PPS composite material is prepared from the following components in parts by weight: 80 to 100 parts of PPS, 10 to 16 parts of dielectric filler, 8 to 12 parts of basalt fiber, 0.2 to 0.4 part of SEBS-g-MAH (styrene-ethylene-butylene-styrene-graft-maleic anhydride) and 0.1 to 0.5 part of antioxidant. Wherein the dielectric filler is composed of Mg (at) ZrO2 (at) PDA nano-particles, and the surface of nano-particles ZrO2 is sequentially coated with PDA and Mg nano-particles, so that the dielectric filler is formed. The dielectric filler and the basalt fiber are added into the PPS resin matrix to improve the dielectric property and the mechanical property of the PPS composite material, so that the application of the PPS composite material is expanded. 本发明公开了一种PPS复合材料及其制备方法，所述的PPS复合材料由以下组分按照重量份制备而成：PPS 80份-100份，介电填料10份-16份，玄武岩纤维8份-12份，SEBS-g-MAH0.2份-0.4份和抗氧剂0.1份-0.5份；其中，所述介电填料的组成为Mg@ZrO2@PDA纳米颗粒，其是在纳米颗粒
