The invention discloses a high-strength PVC (polyvinyl chloride) pipe material. The high-strength PVC pipe material comprises a PVC layer, a bonding layer and a carbon fiber cloth layer; the carbon fiber cloth layer wraps the outer part of the PVC layer through the bonding layer; a plurality of reinforced connecting grooves are formed in the surface of the outer side of the PVC layer; four reinforced ribs are horizontally arranged on the inner side of the PVC layer; the PVC layer comprises the following raw material componentsincluding, by weight,30-35 parts of PVC resin, 15-20 parts of chlorinated polyethylene, 10-15 parts of ethylene-propylene rubber, 5-8 parts of acetylene-propylene copolymer, 2-4 parts of a stabilizer, 8-12 parts of filler and 1-3 parts of beta-cyclodextrin. Through the reinforced ribs, the internal supporting strength of the PVC pipe is enhanced and use in actual life is facilitated; and through the carbon fiber cloth layer, the carbon fiber cloth layer has high strength, low density and small thickness, does not increase the self-weight of a reinforcing component and the section size, is suitable for various structure types and greatly enhances the external supporting strength of the PVC pipe.
