Title:
CORROSION-RESISTANT GRAPHENE OIL DELIVERY PIPE AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/119404
Kind Code:
A1
Abstract:
A corrosion-resistant graphene oil delivery pipe, comprising a PVC (polyvinyl chloride) polyethylene inner layer (1); adhesion assisting holes (2) are uniformly arranged on the outer wall of the PVC polyethylene inner layer, the outer wall of the PVC polyethylene inner layer (1) is coated with a butyl rubber layer (3), the outer wall of the butyl rubber layer (3) is uniformly coated with an antistatic layer (4), cushion rubber lugs (5) are uniformly and annularly adhered on the outer wall of the antistatic layer (4) by means of an adhesive, the outer wall of the butyl rubber layer (3) is wrapped with a metal mesh layer (6), the cushion rubber lugs (5) are positioned between the butyl rubber layer (3) and the metal mesh layer (6), and the outer wall of the metal mesh layer (6) is coated with a graphene outer layer (7). Further disclosed is a preparation method for the corrosion-resistant graphene oil delivery pipe. The corrosion-resistant graphene oil delivery pipe is provided with an antistatic layer, such that the phenomenon that delivered petroleum is ignited due to static electricity generated in use of the oil delivery pipe is avoided; the PVC polyethylene inner layer, good in corrosion resistance, is disposed to be in a direct contact with petroleum; and the graphene outer layer with anti-corrosion property protects the outer wall of the oil delivery pipe.
