▎ 摘  要

NOVELTY - Method for preparing a corrosion-resistant petroleum buried pipe involves (i) soaking basalt fiber unidirectional cloth in a soaking solution and drying the basalt fiber unidirectional cloth until the moisture content is less than 0.1%, (ii) uniformly infiltrating the dried basalt fiber unidirectional cloth in graphene oxide modified epoxy resin, (iii) uniformly winding the basalt fiber unidirectional cloth infiltrated with the graphene oxide modified epoxy resin on the outer side of steel pipe and (iv) placing the steel pipe wound with the basalt fiber unidirectional cloth in a mold, closing the mold, demolding and cooling to obtain the petroleum buried pipe, where the graphene oxide modified epoxy resin is prepared from epoxy resin powder, graphene oxide and acetone. USE - The method for preparing a corrosion-resistant petroleum buried pipe. ADVANTAGE - The method provides the petroleum buried pipe with excellent corrosion resistance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for the corrosion-resistant petroleum buried pipeline comprising the product prepared by the method.
