Description

technical field [0001] The invention relates to the technical field of coating compositions, in particular to a flame-retardant and anti-corrosion coating for outdoor power equipment and a preparation method thereof. Background technique [0002] The installation locations of most power equipment in my country are mainly chosen outdoors. In this case, the power equipment is subjected to wind, sun, and other natural environments all year round. The surface is easily corroded, dust and aging, and the probability of accidents is low. become relatively large, so the protection of electrical equipment is very important. [0003] For a long time, people have been using a variety of technologies to protect power equipment and prevent corrosion. Among them, one of the most effective and commonly used methods for anti-corrosion of electrical equipment is to apply an anti-corrosion coating on the surface of electrical equipment to isolate the corrosive medium from the substrate. Anti...
