[0045] A second aspect of the present invention provides a method for preparing a high-performance wear-resistant coating material; comprising the following steps:
[0046] (1) Stir and disperse the toughening agent and thermosetting resin according to the above ratio, and heat at a temperature of 90-100°C for 1-2 hours to obtain a prepolymer;
[0047] (2) Add the prepolymer, auxiliary materials and fibers in the step (1) according to the above ratio for stirring and dispersing, and the stirring time is 5-10 minutes;
[0048] (3) Stir 60wt%-80wt% organosilicon material and main ingredients according to the above ratio for 5-10 minutes, then add the substances in step (2) and stir for 5-10 minutes;
[0049] (4) Stir 20wt%-40wt% organosilicon material and stabilizer for 5-10 minutes, then add the substances in step (3) and stir for 5-10 minutes to obtain the required high-performance wear-resistant coating Material.
