Anion-releasing wear-resistant coating and preparation method thereof

The invention relates to a wear-resistant coating capable of releasing negative ions and a preparation method thereof, and belongs to the technical field of coating compositions. The coating comprises the following components in parts by weight: 50-70 parts of heavy calcium carbonate, 10-16 parts of seaweed mud, 6-8 parts of cast stone powder, 6.5-9 parts of a negative ion generating agent, 1.2-1.8 parts of carboxyl cellulose and 1.5-2 parts of redispersible rubber powder, wherein the negative ion generating agent takes tourmaline powder as a core, a porous cerium and zirconium oxide coating structure is formed through chelating adsorption and conversion roasting decomposition, the negative ion generating agent has good water retention and photocatalysis effects, the moisture absorption and air permeability of the coating are improved with the assistance of seaweed mud, generation and release of negative ions are facilitated, and it is detected that the negative ion generating agent has good water retention a
