[0018] The superhard anti-yellowing epoxy floor paint, the paint is composed of A component and B component, and the A component includes the following raw materials: by weight, 45 parts of bisphenol A epoxy resin, glycerin epoxy resin 8 parts of resin, 8 parts of phenyl glycidyl ether, 1 part of cyclohexanol, 20 parts of precipitated barium sulfate, 40 parts of quartz powder, 10 parts of color paste, 0.5 parts of silicon carbide powder, 0.6 parts of AKN-2048, 0.05 parts of AKN-33570 , AKN-157B 0.8 parts, anti-yellowing agent 0.8 parts;

[0019] Component B includes the following raw materials: by weight, 40 parts of methyltetrahydrophthalic anhydride and 1 part of dihydroxydiethylenetriamine.

[0020] The mass ratio of the A component to the B component is 3:1.

[0021] The preparation method is: mix and stir components A and B for 0.5~1h,

Embodiment 2

[0023] The superhard anti-yellowing epoxy floor paint, the paint is composed of A component and B component, A component includes the following raw materials: by weight, 48 parts of bisphenol A epoxy resin, glycerin epoxy resin 9 parts of resin, 9 parts of phenyl glycidyl ether, 3 parts of cyclohexanol, 25 parts of precipitated barium sulfate, 45 parts of quartz powder, 11 parts of color paste, 0.7 parts of silicon carbide powder, 0.8 parts of AKN-2048, 0.1 parts of AKN-33570 , 0.9 parts of AKN-157B, 0.9 parts of anti-yellowing agent, 5 parts of modified polyimide fiber, 0.3 parts of BYK360, 2 parts of isopropanol.
