The invention relates to high wear-resistant 
epoxy coating, a preparation method of high wear-resistant 
epoxy coating and a high wear-resistant 
epoxy coating layer. The high wear-resistant epoxy coating provided by the invention is characterized by being prepared from an A component and a B component, wherein (1) the A component is prepared from the following raw materials in percentage by 
mass: 45 to 55 percent of epoxy resin, 3 to 5 percent of 
toughening agent, 3 to 5 percent of diluting agent, 5 to 10 percent of accelerator, 2 to 5 percent of 
silane coupling agent, 20 to 25 percent of 
abrasive aggregates, 5 to 10 percent of filler and appropriate percent of 
pigment; (2) the B component is prepared from the following raw materials in percentage by 
mass: 15 to 20 percent of MXDA (M-Xylylenediamine), 15 to 20 percent of IPDA (
Isophorone Diamine), 3 to 5 percent of 1,3-BAC (1,3-bis(aminomethyl)-cyclohexan), 25 to 35 percent of polyether amine D230, 25 to 30 percent of styrenated 
phenol and 5 to 10 percent of 
TMPTA (
Trimethylolpropane triacrylate); the A component and the B component are mixed according to a proportion of 1:5. The high wear-resistant epoxy coating disclosed by the invention has excellent 
wear resistance, high 
hardness, good 
heat resistance and 
water resistance, good chemical 
reagent corrosion resistance, high fullness, high construction efficiency, convenience in construction and a wide application range.
