Description

technical field [0001] The invention relates to the technical field of two-component epoxy coatings, in particular to an antirust two-component epoxy coating for ship hulls. Background technique [0002] In recent years, with the rapid development of the national economy and the sustained growth of the steel industry, the market demand for long-lasting steel structure anti-corrosion coatings is increasing day by day. Through the comprehensive evaluation of the anti-corrosion performance, construction process and later coating maintenance of epoxy coatings, it has higher cost performance and quality assurance as a heavy-duty anti-corrosion supporting system for domestic large-scale steel structure anti-corrosion projects, and has wide application value and prospects; Oxygen coatings are the development direction of anti-corrosion coatings. The anticorrosion coatings for steel structures in the prior art generally have poor cathodic disbonding resistance and cannot meet the n...
