Basalt fiber brush manufacturing step (S500)

Referring to FIGS. 6 and 7 , the basalt fiber brush CB may be manufactured by bundling a plurality of the fiber bundles FG into a predetermined shape. According to one embodiment, a plurality of the fiber bundles (FG), as shown in Figure 6, can be bundled in a circular shape filled in the center. Alternatively, according to another embodiment, the plurality of fiber bundles (FG) may be bundled in a circular shape with an empty central portion, as shown in FIG. 7 . Alternatively, according to another embodiment, as shown in FIG. 8, the fiber bundle (FG) may be used alone. That is, the shape of the basalt fiber brush CB may be variously modified according to the purpose of use of the basalt fiber brush CB.

As a result, the method for manufacturing a basalt fiber brush according to an embodiment of the present invention is a resin mixture (BR) in which a base resin (eg, epoxy resin), abrasive particles (eg, silicon carbide), and a curing agent are mixed. preparing, impregnating a plurality of basalt fibers (BF) into the resin mixture (BR), and coating the plurality of basalt fibers (BF) with the resin mixture (BR); ) Agglomeration of a plurality of the basalt fibers (BF) coated to prepare the fiber bundle (FG), heat treatment of the fiber bundle (FG), the resin mixture (BR) coated on the basalt fiber (BF) ), and manufacturing the basalt fiber brush (CB) by binding a plurality of the fiber bundles (FG).

Accordingly, in the basalt fiber brush (CB), a plurality of the fiber bundles (FG) are bundled to form a predetermined shape, and the fiber bundle (FG) includes the base resin (eg, epoxy resin) and abrasive particles. The plurality of basalt fibers coated with the resin mixture in which (eg, silicon carbide) is mixed may be bundled such that the extension directions of the adjacent basalt fibers are parallel to each other.

In particular, the basalt fiber brush (CB) according to the above embodiment, as the basalt fiber is used as the main fiber constituting the brush, compared to conventional metal brushes, nylon brushes, and glass fiber brushes, durability and post-processing of cutting parts Performance can be improved. In addition, compared to conventional mullite fiber brushes, manufacturing costs can be significantly reduced, which has an economic advantage.

In the above, the basalt fiber brush and the manufacturing method thereof according to the embodiment of the present invention have been described. Hereinafter, a basalt fiber brush according to a modified example of the present invention will be described.

9 is a view for explaining a basalt fiber brush according to a first modified example of the present invention.

Referring to FIG. 9 , the basalt fiber brush CB according to the first modified example may be the same as the basalt fiber brush CB according to the embodiment described with reference to FIG. 6 . That is, in the basalt fiber brush (CB) according to the first modified example, a plurality of fiber bundles (FG) are bundled to form a certain shape, and the fiber bundle (FG) is made of a base resin (eg, epoxy resin) It may include a plurality of basalt fibers coated with a resin mixture in which abrasive particles (eg, silicon carbide) are mixed, and agglomerated such that the extension directions of each of the adjacent basalt fibers are parallel to each other.

However, the basalt fiber brush CB according to the first modified example includes the first fiber bundle FG ₁ disposed in the central portion and the second to seventh fiber bundles FG ₁ disposed to surround the first fiber bundle FG 1 . Compositions of the fiber bundles (FG ₂ to FG ₇ ) may be different. According to one embodiment, the content of the abrasive particles (eg, silicon carbide) in the first fiber bundle (FG ₁ ) may be relatively low. On the other hand, the second to seventh fiber bundles (FG ₂ to FG ₇ ) may have a relatively high content of the abrasive particles (eg, silicon carbide). That is, the content of the abrasive particles of the fiber bundles FG ₂ to FG ₇ disposed on the outside may be higher than the content of the abrasive particles of the fiber bundles FG ₁ disposed on the inside.

As a result, not only the post-processing performance of the cutting part of the basalt fiber brush CB can be improved, but also the durability of the basalt fiber brush CB can be improved. Specifically, in the case of the basalt fiber brush (CB) used in the process of post-processing the cutting part of the cut part, the frequency of contact between the outside of the brush and the part may be higher than the frequency of contact between the inside of the brush and the part. Accordingly, by increasing the content of the abrasive particles (eg, silicon carbide) on the outside of the brush with high contact frequency, not only can the performance of post-treatment of the cutting part of the basalt fiber brush CB be improved, but also durability can improve together.

10 is a view for explaining a basalt fiber brush according to a second modified example of the present invention.

Referring to FIG. 10 , the basalt fiber brush CB according to the second modification may be the same as the basalt fiber brush CB according to the embodiment described with reference to FIG. 6 . That is, in the basalt fiber brush (CB) according to the first modified example, a plurality of fiber bundles (FG) are bundled to form a certain shape, and the fiber bundle (FG) is made of a base resin (eg, epoxy resin) It may include a plurality of basalt fibers coated with a resin mixture in which abrasive particles (eg, silicon carbide) are mixed, and agglomerated such that the extension directions of each of the adjacent basalt fibers are parallel to each other.

However, in the basalt fiber brush CB according to the second modified example, the first fiber bundle FG ₁ disposed in the central portion and the second to seventh fiber bundles FG ₁ disposed to surround the first fiber bundle FG 1 The fiber bundles (FG ₂ to FG ₇ ) may have different thicknesses. According to one embodiment, the first fiber bundle (FG ₁ ) may have a relatively thin thickness. On the other hand, the second to seventh fiber bundles (FG ₂ to FG ₇ ) may have a relatively thick thickness. That is, the thickness of the fiber bundles (FG ₂ to FG ₇ ) disposed on the outer side may be greater than the thickness of the fiber bundles (FG ₁ ) disposed on the inner side.

As a result, not only the post-processing performance of the cutting part of the basalt fiber brush CB can be improved, but also the durability of the basalt fiber brush CB can be improved. Specifically, in the case of the basalt fiber brush (CB) used in the process of post-processing the cutting part of the cut part, the frequency of contact between the outside of the brush and the part may be higher than the frequency of contact between the inside of the brush and the part. Accordingly, by increasing the outer thickness of the brush with high contact frequency, it is possible to improve not only the post-processing performance of the cutting part of the basalt fiber brush (CB), but also the durability.

In the above, the present invention has been described in detail using preferred embodiments, but the scope of the present invention is not limited to specific embodiments, and should be interpreted according to the appended claims. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.
