The invention relates to a reinforced polyphenylene sulfide composite material for a battery cover plate and a preparation method of the reinforced polyphenylene sulfide composite material. The reinforced polyphenylene sulfide composite material comprises the following components in parts by weight: 20-40 parts of polyphenylene sulfide; 1-5 parts of a compatilizer; 1-3 parts of a resin cross-linking agent; 35 to 50 parts of glass fiber; 10 to 30 parts of mineral whisker; 0.5-2 parts of an acid acceptor; the compatilizer is a glycidyl methacrylate grafted styrene-ethylene/butylene-styrene copolymer, and the grafting rate of glycidyl methacrylate is 2-3%; the preparation method comprises the following steps: uniformly mixing polyphenylene sulfide, a compatilizer, a resin cross-linking agent, mineral whiskers and an acid acceptor to obtain a mixture, respectively adding the mixture and glass fibers from a main feeding port and a side feeding port of a double-screw extruder, and carrying out melt extrusion granul
