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] Use a fiber holder to continuously arrange the basalt fibers with a diameter of 16 microns in a row in a fixed arrangement at both ends, control the length of the fiber at 20mm, and then put the glass fiber together with the fiber holder 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 vertically to impact the above-mentioned coating, and the coating does not fall off. , without cracks.

Abstract

The invention relates to a preparation method of a scale material, comprising: arranging glass fibers or basalt fibers in a row continuously, heat-treating at 850-1150°C for 5-20 minutes, and then annealing at 500-800°C for 1-5 hours to obtain the scale material . The process of the invention is simple, the prepared scales have high flatness, and the maximum number of layers can be filled in the coating, and each scale has many grooves at the fiber joints, which greatly increases the surface friction between the scales and the resin, and can effectively Improve the performance of anti-corrosion coatings.

Description

technical field [0001] The invention belongs to the technical field of scale materials, in particular to a preparation method of scale materials. Background technique [0002] With the development of modern industry, the petroleum industry, chemical industry and ocean development industry have put forward higher and higher requirements for anti-corrosion technology. These industrial fields have been in harsh corrosive environments for a long time, and general anti-corrosion materials can no longer meet the needs of industrial production. . The emergence of glass flakes, a heavy-duty anti-corrosion material, has attracted the attention of the material industry for its excellent anti-corrosion performance and relatively simple construction methods. The research on glass flake materials began in the 1950s. It was first developed by the Owens-Corning Fiberglass Company of the United States. Using glass flakes as filler, the resulting coating has excellent impermeability, and t...
