Also, due to the rapid reaction of isocyanates with amines, the coating has poor wetting of the substrate, resulting in poor adhesion
[0005] The patent number is: CN99124013.8, CN200610049566.9 two patent documents record content, it can be seen that the fusion-bonded epoxy powder coating disclosed by it needs to be coated in a special coating production line. Therefore, the fusion-bonded epoxy powder coating is most suitable for pipes with uniform specifications and large batches, while other applications are subject to certain restrictions. For example, it is not suitable for thin-walled steel plates and cannot be recoated. Variety

Embodiment 1
[0027] A, B, C component composition, by mass percentage:
[0041] According to the proportion of raw materials, three components A, B and C are prepared, and the components A, B and C are mixed according to the ratio of 100:20:200 to prepare a sample plate and measure the coating performance.
[0042] The method of use is to treat the base material with sandblasting or shot blasting to Sa2.5 level, mix A, B, and C components evenly in proportion, and apply it by scraping. The thickness of one layer can reach 500 microns.
[0043] The heavy-duty anti-corrosion coating for marine steel structure produced by the above ratio has the following performance indicators:

Abstract
The invention relates to a heavy-duty coating used in ocean steel structure, which adopts three-component combination; wherein, A component consists of epoxy resin, a plasticizer, a flatting agent and a defoamer; B component is an epoxy curing agent; C component consists of wear-resistant pigment, alkaline water absorbent, antirust pigment and anti-cracking pigment; the weight percentage of each component are that: A component: 60 to 100 parts of epoxy resin, 10 to 30 parts of plasticizer, 0.1 to 1 part of flatting agent, and 0.1 to 1part of defoamer; B component: epoxy curing agent; C component: 60 to 100 parts of wear-resistant agent, 30 to 50 parts of alkaline water absorbent, 2 to 10 parts of antirust pigment and 2 to 10 parts of anti-cracking pigment. Before coating, A component and B component are mixed evenly according to certain proportion, and C component is added according to proportion; the mixture is mixed evenly; the proportion of the three components can be adjusted within certain scope according to the difference of construction environment temperature, and the proportion of A, B, and C components is 100: 20: 200 when temperature is 25 DEG C. The heavy-duty coating used in ocean steel structure has good adhesion, abrasion resistance, and corrosion resistance.
Description
technical field [0001] The invention relates to the technical field of anti-corrosion coatings, in particular to a heavy-duty anti-corrosion coating for marine steel structures. Background technique [0002] There are three kinds of heavy-duty anti-corrosion coatings with similar purposes in the known technology: polyester glass flake coatings, spray polyurea coatings and fusion bonded epoxy powder coatings. [0003] According to foreign literature reports, polyester glass flake coatings have been used in offshore drilling platforms. Polyester resin is free radical polymerization through an initiator, and the polymerization speed is fast, accompanied by exotherm. Therefore, polyester glass flake coatings are generally applied with a two-component sprayer. The surface of the coating will prevent curing due to exposure to oxygen in the air. Therefore, the surface of the paint film must be isolated from oxygen with paraffin, otherwise, the surface of the paint film will be dif...
