Abstract

The invention provides a wear-resistant thermosetting powder coating for oil pipelines and a preparation method thereof. The coating is made of raw materials including the following mass fractions: thermosetting epoxy resin: 30%-60%, curing agent: 4.5%-30%, Pigment and / or filler: 20% to 30%, auxiliary agent: 2% to 12%; the curing agent is one or more of dicyandiamide, modified dicyandiamide and sebacic acid dihydrazide In combination with a phenolic hydroxyl resin, the phenolic hydroxyl resin is a phenolic curing agent with an interpenetrating structure and containing polyfunctional groups of hydroxyl, amide and amine groups with a hydroxyl value of 0.5-0.7 mol / 100g. The invention is simple to operate, easy to realize industrialized production, the product is used for coating oil pipelines, and the labor production efficiency of coating is high; the utilization rate of the coating can reach more than 98%; the coating has good adhesion between the substrate , excellent wear resistance, and more environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of thermosetting powder coatings, and in particular relates to a wear-resistant thermosetting powder coating for oil pipelines and a preparation method thereof. Background technique [0002] Due to the fact that certain impurities will be produced during oil extraction and other links, oil and gas gathering and transportation pipelines often contain a certain amount of solid particles. These sandy fluids impact the inner wall of the pipeline and cause a certain degree of erosion and wear to it, which will eventually affect normal production and may cause pipeline leakage. For oil pipelines, corrosion, scaling, waxing, and wear are the four major public hazards, which always accompany this life cycle. In order to solve the problem of oil pipelines, it is urgent to develop a pipeline coating that is corrosion-resistant, wear-resistant, and has low transmission resistance, but the coatings currently used on oi...
