Abstract

The invention relates to an anticorrosive coating and provides a solvent-free anticorrosive coating for solving the problem that imported underwater applicable coatings are high in cost and domestic underwater applicable coatings are low in coating adhesion, shorter in validity period and the like. The solvent-free anticorrosive coating consists of a component A accounting for 64%-72% of the total weight of the coating, a component B accounting for 16%-20% of the total weight of the coating and a component C accounting for 12%-16% of the total weight of the coating and is an epoxy solvent-free coating. The solvent-free anticorrosive coating is good in underwater applying effect, high in coating adhesion, long in validity period ad good in anticorrosive performance, the cost is remarkably lower than those of the imported coatings, and the problem that the imported coatings are high in cost is solved. Actual coating shows that the solvent-free anticorrosive coating is good in curing effect, film forming effect and coating uniformity, the amount of entrained water in the coating process is small, the water flow influence on coating process is small, and the solvent-free anticorrosive coating is suitable for direct underwater construction in the field of ocean engineering.

Description

technical field [0001] The invention relates to an anticorrosion coating, in particular to a solvent-free anticorrosion coating. Background technique [0002] In recent years, my country has developed rapidly in the field of marine engineering, and has made great progress in many aspects such as port facilities and shipbuilding industry. Due to the high level of corrosion in the marine environment, the rapid development of marine engineering has also brought a lot of demand for coatings. However, there is still a large gap between my country's overall level in the coating field and the international leading technology, and the price of imported coatings is generally expensive, so a large number of imported coatings lead to high coating costs, which has raised the cost of marine engineering as a whole. total cost. [0003] In actual engineering, for the coating of underwater parts of facilities such as port terminals, offshore drilling platforms, and sea-crossing bridges, it...
