Description

Technical Field

[0001] The invention relates to an easy-to-clean aspartame polyurea anticorrosive coating and a preparation method thereof, and is applied in the field of anticorrosive coating production. Background Art

[0002] Polyaspartic acid ester polyurea material, referred to as aspartic polyurea, is a new type of aliphatic polyurea that has appeared in the polyurea industry in recent years, and is also known as the third generation of polyurea. Aspartic polyurea coatings are widely used in petrochemicals, wind turbine blades, special containers, engineering machinery, marine heavy-duty anti-corrosion, automobiles, high-end industrial and commercial flooring, waterproofing and other fields due to their excellent comprehensive performance. However, it is currently found in the applications of some engineering machinery, marine equipment, etc. that the stains on the paint film are difficult to clean after high-intensity wear, and even break after strong impact, which affects the overall appearance of the coating and the comprehensive anti-corrosion performance of the matching coating.

[0003] Therefore, it has become an urgent task to provide an easy-to-clean asparagus polyurea anti-corrosion coating with excellent impact resistance and corrosion resistance and a preparation method thereof. Summary of the invention
