Embodiment 1
[0022] Use a fiber holder to arrange the E-glass fibers with a diameter of 6 microns in a continuous row in a fixed arrangement at both ends, control the length of the fiber at 15mm, and then put the glass fiber together with the fiber holder into a silicon carbide rod electric furnace. Heat treatment at 980°C for 8min, and then anneal at 650°C for 2h to obtain two-dimensional glass flakes.
[0023] The thickness of the glass flakes obtained in this embodiment is 6 microns, and the thickness of the glass flakes in the longitudinal direction is generally 200-1000 microns after crushing.
[0024] Utilize the glass flakes prepared in this example, the mass fraction is 25%, and epoxy resin is used to prepare the glass flake anti-corrosion coating, and a 500g heavy steel ball is dropped from a height of 500mm to impact the above coating, and the coating does not fall off. , without cracks.

Embodiment 2
[0027] Using a fiber holder, the basalt fibers with a diameter of 16 microns are continuously arranged in a row in a fixed arrangement at both ends, and the length of the fiber is controlled at 20mm, and then the glass fiber and the fiber holder are put into a silicon carbide rod electric furnace, Heat treatment at 1150°C for 12 minutes, and then annealing at 850°C for 3 hours to obtain two-dimensional basalt scales.
[0028] The thickness of the basalt flakes obtained in this example is 16 microns, and generally 100-500 microns after crushing in the longitudinal direction.
[0029] Utilize the basalt flakes prepared in this embodiment, the mass fraction is 25%, and epoxy resin is used to prepare the basalt flake anti-corrosion coating, and a 500g heavy steel ball is dropped from a height of 500mm to impact the above-mentioned coating, and the coating does not fall off. , without cracks.
