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.

Abstract

The invention relates to a preparation method of a scale material. The method comprises the following steps of continuously arranging glass fiber or basalt fiber into one row; performing heat treatment at 850 to 1150 DEG C for 5 to 20 min; then, performing annealing for 1 to 5 h at 500 to 800 DEG C to obtain the scale material. The method has the advantages that the process is simple; the preparedscale has high flatness degree and can be filled into a coating at the maximum layers; in addition, a plurality of grooves are formed in fiber connecting parts of each scale, so that the surface friction between the scales and the resin is greatly improved; the performance of anti-corrosion coating can be effectively improved.

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...
