Description

Technical Field

[0001] The utility model belongs to the technical field of epoxy paint coatings, in particular to a corrosion-resistant epoxy paint coating structure. Background Art

[0002] A coating is a solid continuous film obtained by applying the paint once. It is a thin layer of plastic applied to substrates such as metal, fabric, and plastic for the purpose of protection, insulation, and decoration. The paint can be in gaseous, liquid, or solid state. The type and state of the paint are usually determined by the substrate to be sprayed. In order to reduce pollution from organic solvents, the paint needs to be fully developed.

[0003] After searching, Chinese patent application number 202122858708.9 discloses a corrosion-resistant epoxy paint coating structure. This patent relates to the field of epoxy paint coating technology and discloses a corrosion-resistant epoxy paint coating structure. A corrosion-resistant epoxy paint coating structure includes a substrate layer, characterized in that: an insulating layer is fixedly installed on one side of the substrate layer, a heat-resistant layer is fixedly installed on the side of the insulating layer away from the substrate layer, a corrosion-resistant layer is fixedly installed on the side of the heat-resistant layer away from the insulating layer, a wear-resistant layer is fixedly installed on the side of the corrosion-resistant layer away from the heat-resistant layer, and a waterproof layer is fixedly installed on the side of the wear-resistant layer away from the corrosion-resistant layer. The water-based inorganic zinc-rich resin in the corrosion-resistant layer has excellent anti-corrosion properties. The inorganic zinc-rich primer mixed with zinc powder can be resistant to salt spray and rust for up to 8,000 hours after curing. The paint film has excellent resistance to seawater, atmospheric corrosion, acid, alkali, and salt corrosion. It is non-toxic and odorless, zero VOC, non-flammable, non-explosive, meets environmental protection requirements, and is a green and environmentally friendly product.

[0004] Although the above patent solves the problem that some paint coatings are relatively weak in terms of corrosion and oxidation resistance, resulting in low resistance of epoxy coatings during long-term use, which is not conducive to improving environmental protection performance, in actual application, the patent lacks a reinforcement structure for the epoxy paint coating structure, which makes it possible for the epoxy paint coating structure to decompose and crack when used in some places, thereby causing its corrosion resistance to be compromised, thereby reducing the service life of the epoxy paint coating structure.

[0005] Therefore, it is necessary to modify the epoxy paint coating structure in the above patent to effectively prevent the epoxy paint coating structure from being damaged by frequent cargo handling and personnel movement when used in some places, thereby causing its corrosion resistance to be compromised, thereby resulting in a reduction in the service life of the epoxy paint coating structure.
