Problems solved by technology

However, when basalt flakes are used in water-based anti-corrosion coatings, due to their surface inertia, the dispersion and stability in the resin are relatively poor, and they are easy to settle, resulting in a decrease in the performance of the coating.

Description

technical field [0001] The invention belongs to the technical field of anti-corrosion coatings, and in particular relates to an anti-corrosion coating for wheel rims containing basalt scales and a preparation method thereof. Background technique [0002] Basalt scale is a new type of scale material. It is a new type of material processed by selecting natural basalt ore with excellent performance through special processes such as high-temperature melting, clarification, homogenization, and screening. It presents a transparent or dark green sheet structure. It can not only produce Shielding effect, and also has unique advantages in acid and alkali resistance and corrosion resistance, especially the stable high and low temperature resistance of basalt, as well as excellent dielectric and chemical resistance, making it widely used in coatings, construction, national defense, military, Highway, railway and other fields have great development prospects. [0003] With the continuo...
