The invention belongs to the technical fields of plastic conduit, provide a kind of buried corrosion-resistant PVC plastic pipeline and preparation method for saline-alkali tolerant.This method combs networking with aramid short fiber and aramid fiber fibrid, and intersects and be laid with continuous basalt fiber and the obtained non-woven fabrics of aramid short fiber, then binding resin is infiltrated, the surface of pvc pipe is closely coated in a manner of spiral winding, then adds one layer of corrosion-resistant sheath outside pipe.Compared with conventional method, the pvc pipe corrosion resistance of preparation of the invention is strong, and saline-alkali tolerance can be good, and service life is long, while mechanical property is good, and application performance is good, can be widely used for the buried tubing in varieties in saline-alkali areas. |
