Abstract

The invention discloses a powder anticorrosion coating for submarine pipelines, which is composed of the following raw materials in parts by weight: 20-50 parts of epoxy resin, 20-50 parts of novolak epoxy resin, 5-30 parts of titanium dioxide, trimethyl 4‑10 parts of hexamethylenediamine, 1‑2 parts of polyvinyl butyral, 3‑4 parts of defoamer, 0.1‑0.2 parts of dimethylimidazole, 1‑2 parts of antioxidant DNP, aminopropyl 1-3 parts of triethoxysilane, 5-26 parts of barium sulfate, 2-10 parts of thickener, 0.5-5 parts of graphene, and 0-4 parts of colorant. The powder anticorrosion coating for submarine pipelines of the present invention can protect steel structures from corrosion of various corrosive media for a long time, is non-toxic, non-polluting, resistant to salt spray, strong in adhesion, strong in impact resistance, and low in cost, and is an environmentally friendly coating with excellent comprehensive performance. coating.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to powder anticorrosion coatings for submarine pipelines. Background technique [0002] In today's society, land oil is increasingly depleted, and people turn their attention to the sea, where abundant oil and natural gas resources are stored, and the competition for offshore oil and gas has become the focus of attention of all countries in today's society. At present, the development of offshore oil and gas resources usually adopts submarine pipeline transportation, which has the outstanding advantages of high safety performance and low cost, and has been adopted by most countries in the world. Natural gas exploration, development and oil and gas transportation started relatively late. Domestic submarine oil and gas pipelines have a large gap with foreign products in terms of mechanical properties, corrosion resistance and service life. Therefore, it is imminent to prolong the li...
