Embodiment 1

[0018] A special anti-corrosion coating material for the surface of straight seam welded pipes, which is prepared from the following components by weight: 100g of epoxy resin, 5g of mineral powder, 0.1g of graphene microflakes, 1g of sepiolite powder, 5g of pigment, and nano-titanium carbide 10g, selenium powder 0.5g, rare earth oxide 1g, curing agent 0.5g, wax powder 15g, leveling agent 0.5g, brightener 0.5g, zinc powder 5g, calcined wollastonite powder 1g, nano silicon dioxide 1g;

[0019] The graphene microchips grow graphitic carbon crystals in a three-dimensional honeycomb manner. The four valence electrons of each carbon atom form covalent bonds and are bound, unable to form a directional mobile electron flow, so they cannot conduct electricity. After generation, graphene carbon crystals are ground in a single direction by wet nano-grinding. The thickness of graphene microflakes is minimized to 5nm. By adding graphene micro-sheets into the coating, the surface resistivit...

Abstract

The invention discloses a special anticorrosive coating material for the surfaces of straight welded pipes. The special anticorrosive coating material is characterized by comprising, by weight, 90-150 g of epoxy resin, 4-6 g of mineral powder, 0.05-0.5 g of graphene micro-chips, 0.5-2 g of sepiolite powder, 3-8 g of pigment, 5-15 g of nanometer titanium carbide, 0.4-0.6 g of selenium powder, 0.5-1.5 g of rare earth oxide, 0.5-1 g of curing agents, 10-20 g of wax powder, 0.5-1 g of leveling agents, 0.5-1 g of brighteners, 4-8 g of zinc powder, 0.5-1.5 g of calcined wollastonite powder and 0.5-1.5 g of nanometer silicon dioxide. The special anticorrosive coating material has the advantages that the special anticorrosive coating material is used for realizing anticorrosive effects for the surfaces of the welded pipes, and accordingly corrosion-resistant, impact-resistant and abrasion-resistant effects can be realized by the welded pipes; the special anticorrosive coating material comprises the rare earth oxide, the nano-scale powder and the like, accordingly, anticorrosive layers only can deform without being stripped under impact conditions, loss of the corrosion-resistant capacity can be prevented, and the service lives of the welded pipes can be effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of coating technology, in particular to a special anti-corrosion coating material for the surface of straight seam welded pipes. Background technique [0002] Longitudinal welded pipes, steel pipes made of hot-rolled or cold-rolled steel plates or steel strip coils welded on welding equipment are called straight seam welded pipes, (named because the welded parts of the steel pipes are in a straight line) . According to different uses, there are different post-production processes. The standard for longitudinal welded pipes is GB / T3091-2008. [0003] Straight seam steel pipes are mainly used in water supply projects, petrochemical industry, chemical industry, electric power industry, agricultural irrigation, and urban construction in China. Used for liquid transportation: water supply and drainage. For gas transportation: gas, steam, liquefied petroleum gas. For structural purposes: as piling pipes, as br...
