Abstract

The invention relates to the technical field of coatings, in particular to a water-based anti-corrosion coating for transformers and a preparation method thereof. The water-based anti-corrosion coating is double-layered and includes a water-based epoxy primer and a water-based polyurethane topcoat. The polyurethane coating of PPC has the advantages of safety and environmental protection, good corrosion resistance and high adhesion.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based anti-corrosion coating for transformers and a preparation method thereof. Background technique [0002] Among the equipment used in the power system, the transformer is a key equipment, and its status is directly related to the safe operation of the entire power grid and electrical equipment. With the development of economy and society and the continuous improvement of infrastructure, the demand for transformers is increasing. Transformers are generally installed outdoors, even in coastal and highly corrosive areas with relatively harsh environments. In order to ensure stable operation of equipment, for transformers Corrosion protection is extremely important. Therefore, anti-corrosion coatings for transformers must have good performance. [0003] Coatings, traditionally known as paints. The so-called paint is coated on the surface of the object to be protected ...
