Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a high-corrosion-resistant water-based coating for containers and a preparation method thereof. Background technique [0002] Corrosion is one of the main reasons for the damage of containers, and iron is the main component material of containers. Applying water-based coatings on the iron surface is a common method to prevent its corrosion. However, the existing water-based coatings generally have weak color fastness, poor adhesion, Problems of poor fire resistance and poor corrosion resistance. Contents of the invention [0003] In order to solve the common problems of weak fastness, poor adhesion, poor fire resistance and poor corrosion resistance in the existing high-corrosion-resistant water-based coatings for containers, the purpose of the present invention is to provide a high-corrosion-resistant water-based coating for containers. The coating and the prepar...
