The invention provides PVDC copolymer emulsion. The copolymer emulsion is formed by mixture monomers and accessory ingredients through copolymerizing. The mixture monomer contains 65 percent to 82 percent of vinylidene chloride, 15 percent to 35 percent of unsaturated fatty acid ester monomer, 3 percent to 8 percent of unsaturated fatty acid and 0.001 percent to 2 percent of perfluoro-unsaturated fatty acid C3 to C6 ester monomer. The copolymer emulsion also contains the three-layer structural particles, the core-shell particles of which are all VDC/MMA/BA: the core layer is 20 percent to 84 percent of VDC and 16 percent and 80 percent of comonomer; the middle layer is 80 percent of VDC and 18 percent and 20 percent of comonomer; the outmost layer is 30 percent to 80 percent of VDC, 20 percent and 60 percent of comonomer and trace amount of C3 to C6 perfluoroester. The ratio of each layer is 5 to 30:25 to 70:15 to 30. The invention also provides a preparation method of the copolymer emulsion and an applicatio
