The invention discloses heat-resistant polyvinyl chloride resin and belongs to the technical field of resin preparation. The heat-resistant polyvinyl chloride resin comprises the following raw materials: polyvinyl chloride resin, hydroxyl-terminated polybutadiene, polyphenylene sulfide, methacrylic acid, epoxy resin E-51, coumarone resin, isocyanate, polyphosphate, butylene terephthalate, hydrogenated styrene, low-density polyethylene, nano ceramic powder, nano boron nitride, zinc borate, aluminium triphosphate, nano aluminium oxide, calcium sulfate whiskers, chlorinated paraffin, mica iron oxide, pine tar, polyadipic acid, benzotriazole, aluminium diethylphosphinate, antimony(III) oxide, sodium metaborate, silane coupling agent KH-560 and a heat resistance modifying assistant. The heat-resistant polyvinyl chloride resin is prepared through steps of preparation of a base material, preparation of a modified material, mixing of the base material, the modified material and other materials, and the like.
