This diagram is intended to explain the various shapes of brushes.

Referring to Figure 1, the method of manufacturing a basalt fiber brush according to an embodiment of the present invention includes preparing a resin mixture (S100), coating the resin mixture on a plurality of basalt fibers (S200), and applying the resin. A step of manufacturing a fiber bundle by combining a plurality of basalt fibers coated with the mixture (S300), heat treating the fiber bundle and curing the resin mixture coated on the basalt fiber (S400), and a plurality of the fibers It may include a step (S500) of manufacturing a basalt fiber brush by tying the bundles. Below, each step is described in detail.

Resin mixture preparation step (S100)

Referring to FIG. 2, step S100 includes mixing and stirring the base resin and the grinding particles to prepare a preliminary resin mixture (S110), and mixing and stirring the preliminary resin mixture and the curing agent to prepare the resin. It may include preparing a mixture (S120).

Additionally, the resin mixture can be prepared by mixing the preliminary resin mixture with a curing agent and then stirring it at a speed of 450 rpm for 15 to 20 minutes.

Unlike what was described above, in the step of preparing the preliminary resin mixture, when the epoxy resin and silicon carbide (SiC) are stirred for less than 2 hours or at a speed of less than 450 rpm, the formation of viscosity is not sufficiently achieved, which will be described later.

As described above, by reducing the viscosity of the base resin (e.g., epoxy resin) and then mixing the abrasive particles (e.g., silicon carbide), the base resin (e.g., epoxy resin) and the Mixing of abrasive particles (eg, silicon carbide) can be easily accomplished.

Resin mixture coating step (S200) and fiber bundle manufacturing step (S300)

3 to 5, a plurality of basalt fibers (BF) may be impregnated into the resin mixture (BR). Accordingly, the resin mixture (BR) may be coated on a plurality of the basalt fibers (BF). Thereafter, the plurality of basalt fibers (BF) coated with the resin mixture (BR) may be aggregated. Accordingly, a fiber bundle (FG) can be produced.

According to one embodiment, the resin mixture coating step (S200) includes preparing a plurality of basalt fibers, drying the plurality of basalt fibers, and removing moisture present on the surface of the plurality of basalt fibers. , aligning the plurality of dried basalt fibers laterally, and impregnating the plurality of dried basalt fibers with the resin mixture. More specifically, 200tex basalt fibers can be used as the basalt fibers, and the basalt fibers can be dried at a temperature of 110°C for 24 hours.

On the other hand, when the coating of the resin mixture is performed while the basalt fibers are not dried, a problem may occur in which the coating of the resin mixture (BR) is not performed due to moisture present on the surface of the basalt fibers. there is. In addition, when the coating of the resin mixture is performed in a state where the plurality of dried basalt fibers are not aligned, there is a problem in that the resin mixture is not coated on some of the basalt fibers among the plurality of basalt fibers. It can happen.

As shown in FIG. 5, the plurality of basalt fibers (BF) coated with the resin mixture (BR) may be bundled so that the extension directions of each of the adjacent basalt fibers (BF) are parallel. Accordingly, the fiber bundle (FG), in which a plurality of basalt fibers (BF) coated with the resin mixture (BR) are aggregated, may have a cylindrical shape.

According to one embodiment, coating of the resin mixture (BR) and manufacturing of the fiber bundle (FG) may be performed in the coating module 100 including the impregnation tank 110 and the gather 140. More specifically, the coating module 100 includes an impregnation tank 110 in which the resin mixture (BR) is accommodated, a guide roll rod 120, and first to fifth impregnation roll rods 131, 132, 133, 134, 135. ), and a gather 140 for manufacturing the fiber bundle (FG). Below, each configuration is explained.

The guide roll rod 120 may be disposed on one side of the impregnation tank 110 and outside the resin mixture (BR). The guide roll rod 120 may guide the plurality of basalt fibers (BF) to be impregnated into the resin mixture (BF) contained in the impregnation tank 110.

The first to fifth impregnation roll rods 131, 132, 133, 134, and 135 may be disposed in the resin mixture BR contained in the impregnation tank 110. According to one embodiment, the first to fifth impregnated roll rods 131, 132, 133, 134, and 135 are arranged to be spaced apart from each other and are guided into the resin mixture BR from the guide roll rod 120. The basalt fibers (BF) may sequentially move the first to fifth impregnated roll rods (131, 132, 133, 134, and 135). The plurality of basalt fibers (BF) may move the first to fifth impregnated roll rods 131, 132, 133, 134, and 135 in a zig-zag form. The plurality of basalt fibers (BF) that sequentially move the first to fifth impregnated roll rods (131, 132, 133, 134, and 135) may flow out of the resin mixture (BR). Accordingly, the resin mixture (BF) may be coated on the plurality of basalt fibers (BF). According to one embodiment, the plurality of basalt fibers (BF) may move the first to fifth impregnated roll rods 131, 132, 133, 134, and 135 at a speed of 3 m/min.

The gather 140 may be disposed on the other side of the impregnation tank 110 and outside the resin mixture (BR). The gather 140 is provided with a plurality of basalt fibers (BF) flowing out of the resin mixture (BR) through the first to fifth impregnated roll rods (131, 132, 133, 134, 135). , a plurality of the basalt fibers (BF) can be aggregated. Accordingly, the fiber bundle (FG) in which a plurality of basalt fibers (BF) coated with the resin mixture (BR) are aggregated can be manufactured.

The number of basalt fibers (BF) forming the fiber bundle (FG) may vary depending on the use of the basalt fiber brush (CB), which will be described later. That is, the thickness of the fiber bundle (FG) can be controlled in various ways. For example, the fiber bundle (FG) may have a thickness of 0.3 mm to 1.2 mm and an R/C value of 0.4% to 0.56%. For another example, the thickness of the basalt fibers may be 10 to 20 micrometers, and the fiber bundle may be 100 to 600 tex.

Curing step of the resin mixture coated on the basalt fiber (S400)

The fiber bundles (FG) may be heat treated. Accordingly, the resin mixture (BR) coated on the plurality of basalt fibers (BF) can be cured. Because of this, the shape of the fiber bundle (FG) can be maintained constant. According to one embodiment, the fiber bundle (FG) may be heat treated through a heating module at a temperature of 130°C to 150°C, and may move within the heating module at a speed of 3 m/min.

Basalt fiber brush manufacturing steps (S500)

Referring to FIGS. 6 and 7 , the basalt fiber brush (CB) can be manufactured by binding a plurality of the fiber bundles (FG) in a certain shape. According to one embodiment, the plurality of fiber bundles (FG) may be bundled into a circular shape with a central portion filled, as shown in FIG. 6. Alternatively, according to another embodiment, the plurality of fiber bundles (FG) may be bundled into 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 modified in various ways depending on the intended 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 (e.g., epoxy resin), abrasive particles (e.g., silicon carbide), and a curing agent are mixed. Preparing, impregnating a plurality of the basalt fibers (BF) with the resin mixture (BR), coating the plurality of basalt fibers (BF) with the resin mixture (BR), the resin mixture (BR) ) aggregating a plurality of the basalt fibers (BF) coated to produce the fiber bundle (FG), heat-treating the fiber bundle (FG), and then heat-treating the fiber bundle (FG) to form the resin mixture (BR) coated on the basalt fibers (BF). ), and manufacturing the basalt fiber brush (CB) by binding a plurality of the fiber bundles (FG).

Accordingly, the basalt fiber brush (CB) forms a certain shape by binding a plurality of the fiber bundles (FG), and the fiber bundle (FG) consists of the base resin (for example, epoxy resin) and the grinding particles. The plurality of basalt fibers coated with the resin mixture mixed with (for example, silicon carbide) may be bundled so that the extension directions of each of the adjacent basalt fibers are parallel.

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

Above, the basalt fiber brush and its manufacturing method according to an 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.

Figure 9 is a diagram 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, the basalt fiber brush (CB) according to the first modified example includes a plurality of fiber bundles (FG) bundled together to form a certain shape, and the fiber bundle (FG) is made of a base resin (e.g., epoxy resin). A plurality of basalt fibers coated with a resin mixture of abrasive particles (for example, silicon carbide) may be bundled so that the extension directions of each of the basalt fibers adjacent to each other are parallel.

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

Due to this, not only can the post-treatment performance of the cutting area of the basalt fiber brush (CB) 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 post-processing process of the cutting area of the machined part, the contact frequency between the outside of the brush and the part may be higher than the contact frequency between the inside of the brush and the part. Accordingly, by increasing the content of the abrasive particles (e.g., silicon carbide) on the outside of the brush with high contact frequency, not only can the post-treatment performance of the cutting area of the basalt fiber brush (CB) be improved, but also durability. We can improve together.

Figure 10 is a diagram 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 modified example may be the same as the basalt fiber brush (CB) according to the embodiment described with reference to FIG. 6. That is, the basalt fiber brush (CB) according to the first modified example includes a plurality of fiber bundles (FG) bundled together to form a certain shape, and the fiber bundle (FG) is made of a base resin (e.g., epoxy resin). A plurality of basalt fibers coated with a resin mixture of abrasive particles (for example, silicon carbide) may be bundled so that the extension directions of each of the basalt fibers adjacent to each other are parallel.

However, the basalt fiber brush (CB) according to the second modification example includes a first fiber bundle (FG ₁ ) disposed in the center, and second to seventh fibers arranged to surround the first fiber bundle (FG ₁ ). The thickness of the fiber bundle (FG ₂ to FG ₇ ) may vary. 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 be relatively thick. That is, the thickness of the fiber bundles (FG ₂ to FG ₇ ) disposed on the outside may be thicker than the thickness of the fiber bundle (FG ₁ ) disposed on the inside.

Due to this, not only can the post-treatment performance of the cutting area of the basalt fiber brush (CB) 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 post-processing process of the cutting area of the machined part, the contact frequency between the outside of the brush and the part may be higher than the contact frequency between the inside of the brush and the part. Accordingly, by increasing the thickness of the outside of the brush with high contact frequency, not only can the post-treatment performance of the cutting area of the basalt fiber brush (CB) be improved, but also durability can be improved.

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