The invention discloses a high-flame-retardance polyvinyl chloride resin, and belongs to the technical field of resin preparation. The high-flame-retardance polyvinyl chloride resin comprises: a polyvinyl chloride resin, an epoxy resin, a phenolic resin, poly(phenylene oxide), an EVA resin, diethylene glycol phthalic anhydride polymer, ethylene-vinyl acetate copolymer, trioctyl trimellitate, styrene, dicumyl peroxide, tritolyl phosphate, polycaprolactone, talcum powder, zinc stearate, cerium oxide, antimonous oxide, wood fiber powder, glass fiber, aluminium triphosphate, zinc borate, chlorinated paraffin, epichlorohydrin, maleic anhydride, magnesium hydroxide, a silicane coupling agent KH-560, and a flame-retardant modification auxiliary agent. The high-flame-retardance polyvinyl chlorideresin is made through base material preparation, modification material preparation, and mixing of base materials and modification materials. The prepared polyvinyl chloride resin is excellent in flameretardance. 本发明公开了种高阻燃性聚氯
