Diglycidyl hexahydrophthalate, polyester resin, choline chloride, benzoin, titanium dioxide, light calcium carbonate, Leveling agent, powder flow aid, talcum powder, edge covering agent, anti-caking agent, and pigments are mixed at high speed, melted and extruded, pressed into tablets, crushed, sieved and filtered to make powder coatings; it has no pollution, It has the characteristics of energy saving and environmental protection, good bonding performance, good weather resistance, long service life, and low production cost.

Description

technical field [0001] The invention relates to the technical field of pipeline coating production, in particular to an epoxy powder coating for pipelines and a preparation method thereof. Background technique [0002] Powder coating is an environmentally friendly green coating that does not contain organic solvents. It exists in the form of micropowder, and is applied on the surface of the heated substrate by electrostatic spraying technology, and melted to form a film. Compared with traditional solvent-based coatings, powder coatings have no solvent pollution, easy coating, fast curing speed, and excellent film performance. With the development of petroleum and petrochemical industries, higher requirements are put forward for pipeline coatings. Many traditional anti-corrosion coatings have a single variety, high cost and cannot meet the needs. Contents of the invention [0003] In order to solve the problem that the traditional pipeline coating has a single variety, hig...
