Problems solved by technology

When supplying oil to the high-level oil tank, because the sealing oil entrains a large amount of water and organic matter in the gas, the emulsification of the sealing oil is accelerated during the pumping process, and thick sludge and suspended organic matter are formed in the piston oil groove and the bottom oil groove. Turbidity makes it difficult to control the oil level, and cannot guarantee the sealing effect of the sealing oil and the safe operation of the gas cabinet

Abstract

The invention discloses gas cabinet anti-corrosion paint and a preparation method thereof. The gas cabinet anti-corrosion paint is prepared from a component A and a component B at the mass ratio of 10 to 1, wherein the component A is composed of an organic silicon modified phenolic aldehyde epoxy resin and epoxy polyurethane mixture, a solvent, an anti-settling agent, a dispersant, a foaming agent, a leveling agent, rutile titanium white, a coloring pigment, a sheet-shaped extender pigment, an anti-rusting agent and an incremental agent; the component B is composed of an epoxy-polyamide curing agent and a solvent; and the mass ratio of organic silicon modified phenolic aldehyde epoxy resin to epoxy polyurethane is 1 to (0.8-1.5). By adopting the gas cabinet anti-corrosion paint, the adhesive force and the high-temperature-resisting and acid-alkali-resisting performances of a coating are improved; meanwhile, the water-resisting performance and the salt mist corrosion resisting performance of a coating system are improved and a coating color protection capability is also greatly enhanced; and the long-acting anti-corrosion effect is relatively remarkably improved.

Description

technical field [0001] The invention relates to a paint, in particular to a gas tank anticorrosion paint and a preparation method thereof. Background technique [0002] A gas cabinet is a container device used to store or transport various industrial gases such as biogas, air, carbon dioxide, oxygen, etc., and also to balance the inhomogeneity of the required amount of gas. Such as Wuhan Iron and Steel 120000m 3 Since the Mann type coke oven gas cabinet was put into operation, coke oven gas has been stored and transported. Because coke oven gas contains more organic components such as tar, sulfur, sulfur, and amine, the demulsibility, kinematic viscosity, etc. The indicators are strictly required. When supplying oil to the high-level oil tank, because the sealing oil entrains a large amount of water and organic matter in the gas, the emulsification of the sealing oil is accelerated during the pumping process, and thick sludge and suspended organic matter are formed in the ...
