NOVELTY - Internal drag-reducing coating material comprises 40-50 pts. wt. epoxy resin, 10-20 pts. wt. modified graphene body, 10-20 pts. wt. sepiolite fiber coordinated adjustment solution, 1-3 pts. wt. defoamer, 2-6 pts. wt. reactive diluent, 3-6 pts. wt. phenalkamine curing agent, and 55-65 pts. wt. acetone solvent. USE - The internal drag-reducing coating material is used for geothermal conveying pipeline used in oil exploration and development of petroleum or natural gas, and used in drilling of boreholes. ADVANTAGE - The anti-drag coating material: utilizes epoxy resin as matrix to add modified graphene body, sepiolite fiber synergistic adjusting liquid as complex coordination agent, both of them raw material synergistic effect; enhances the interfacial effect of the product and the performance stability of the improved product; and provides the improved geothermal conveying pipe with improved corrosion resistance. The coating material utilizes epoxy resin as a matrix to add modified graphene body and sepiolite fiber synergistic adjustment liquid as a compound coordinator, and the two raw materials are synergistically synergistic to enhance the interface effect of the product and the performance stability of the product. The sepiolite fiber has a needle-like structure, and the prepared modified graphene body is interspersed in the product system, and further synergizes with the sepiolite fiber synergistic regulator to jointly enhance the interface of the product and optimize the stability of the product under conditions such as acid rot. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing the drag-reducing coating material, comprising stirring and mixing the raw materials in turn until they are fully mixed to obtain a coating agent, and then spraying the substrate to form the coating material.
