Description

technical field

[0001] The invention belongs to the technical field of steel coil coatings, and in particular relates to a highly weather-resistant heat-reflecting steel coil metal coating and a preparation method thereof. Background technique

[0002] With the vigorous development of my country's construction industry, the demand for building materials is increasing year by year. Steel sheet coils are widely used as construction materials such as exterior walls and roofs. Generally, in order to improve the performance of high plate coils, galvanized treatment will be performed on the surface to increase the galvanized layer, thereby endowing the steel plate coils with excellent corrosion resistance, and the steel plate coils are mainly used as outdoor coils, so their weather resistance Sex has higher requirements.

[0003] Coating weather-resistant paint on the surface of the galvanized layer can effectively improve the weather resistance of the galvanized steel sheet. A...
