▎ 摘  要

NOVELTY - Environmentally friendly solvent-free graphene anticorrosive coating comprises 30-40 pts. wt. epoxy resin, 15-20 pts. wt. reactive diluent, 0.15-0.2 pts. wt. graphene, 5-10 pts. wt. additives, 20-25 pts. wt. iron oxide red, 10-15 pts. wt. mica powder, 0.4-0.8 pts. wt. fumed silica, 4-6 pts. wt. barite, 6-10 pts. wt. tripolyphosphate, 0.5-1.5 pts. wt. silane coupling agent, and 7-15 pts. wt. phenalkamine epoxy resin curing agent. USE - Environmentally friendly solvent-free graphene anticorrosive coating. ADVANTAGE - The environmentally friendly solvent-free graphene anticorrosive coating has solid content of 100%, zero volatile organic content (VOC), large specific surface area, good barrier property, high chemical stability and good conductive performance, greatly improves the comprehensive performance and is free of volatile organic solvent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing environmentally friendly solvent-free graphene anticorrosive coating, which involves: (A) weighing each raw material according to the weight ratio; (B) mixing the weighed epoxy resin with the reactive diluent into a dispersion tank and stirring at a high speed for a period of time; (C) adding graphene and auxiliary agent sequentially to the dispersing tank, and then stirring at a high speed for a period of time; (D) adding mica powder, iron oxide red, tripolyphosphate, barite and fumed silica, silane coupling agent, phenalkamine epoxy resin curing agent to the dispersion tank and stirring at high speed a period of time to obtain semi-finished product; and (E) transferring the semi-finished product obtained into a sanding system and dispersing to a fineness of 40-60 mu m, to obtain finished product, which is discharged.
