Abstract
The present invention relates to one kind of paint for pipeline capable of resisting corrosion of sulfate reducing bacteria and its production process. The paint consists of two liquid components, including component A and component B, to be mixed in use. The component A is produced through adding modified phenol phenolic aldehyde type epoxy resin and bisphenol type epoxy resin into mixed solvent; adding chrome oxide green, precipitated barium sulfate, graphite and other seven kinds of material; mixing through stirring and grinding. The component B is produced through adding mannis added and modified polybasic amine into mixed solution. The paint is applied to the inner wall of oil field pipeline to prevent corrosion of sulfate reducing bacteria.
