[Best Mode for Carrying Out the Invention]

Hereinafter, a core material forming method of a non-combustible heat insulating sheet and a method of manufacturing a non-combustible heat insulating sheet according to an embodiment of the present invention will be described with reference to the drawings.

[1] Core material forming method for non-combustible heat insulation board (1) Raw material slat cutting process

Figure 1 shows a portion of the raw material slats of asbestos as a heat insulating material. The asbestos raw material slat 1 is a strip having a predetermined width extending in the Y direction. In this case, the fiber 1a mainly extends in the X direction and the Y direction orthogonal to the X direction. In the present embodiment, first, the asbestos raw material slats 1 are provided with a plurality of cutting lines 2 which are parallel to the X direction at equal intervals in the Y direction. Then, the asbestos raw material slat 1 is cut along the cutting line 2, and a plurality of rectangular solid core blocks 10 having a long length are cut out. The size of the asbestos raw material strip 1 and the core material block 10 may be any size, for example, in the case where the width of the asbestos raw material strip 1 is 2000 mm in the X direction and the thickness is 100 mm, the core material block 10 is cut into The cut width is 25 mm and the length is 2000 mm.

(2) The first core block layer formation process

Fig. 2 shows a plurality of core block bodies 10 cut from the asbestos raw material slats 1. In these core block bodies 10, the fibers 1a extend in the X direction and the Y direction. In the first core material bulk layer forming process, first, as shown in FIG. 3, a predetermined number of core material blocks 10 are traversed by 90 degrees to form a fiber 1a. A state in which the vertical direction (the Z direction in Fig. 1 corresponds to the thickness direction) extends. Therefore, the core block 10 after the traverse is 100 mm in width and 25 mm in thickness (height).

Then, a predetermined number of core block bodies 10 which are traversed into a state in which the fibers 1a extend in the Z direction, that is, in the thickness direction, as shown in FIGS. 4 and 5(a), are adjacent to the core block. The bodies 10 are in contact with each other and the ends in the longitudinal direction (X direction) are aligned in parallel, and the first core block layer 21 on which the adhesive 25 is applied is formed on the upper surface of each of the core block bodies 10.

In order to form the first core block layer 21, a rectangular frame 30 shown in Fig. 6 is used. The mold frame 30 is provided with a long frame 32 and a short frame 33 on the long side and the short side which are formed of an angle material, an aluminum material, or the like, and the long frame 32 and the short frame 33 are arranged, for example. The right frame 32 and the short frame 33 are freely movable on the bottom plate 31 at right angles, and the core block 10 is arranged in the long frame 32 and the short frame 33 to be movable on the movable side. The frame 32 and the short frame 33 are aligned in a parallel state, and by this method, the first core block layer 21 can be formed inside the frame of the long frame 32 and the short frame 33. The width of the core block layer 21 may be any width, for example, 900 mm, that is, in this case, nine core blocks 10 having a width of 100 mm after being traversed may be arranged.

In order to form the state in which the adhesive agent 25 is applied to the upper surface of the core block body 10, any of the following processes may be employed: after the plurality of core material blocks 10 are arranged on the mold frame 30, on the upper surface of the core material blocks 10 The adhesive 25 is applied together, or before being placed on the mold frame 30, the adhesive 25 is applied on the upper surface of each of the core blocks 10, and then the core block 10 to which the adhesive is attached is arranged on the mold frame 30. In the case of the former, it is mainly coated with a sprayer. In the case of the latter, the adhesive 25 may be applied by a spray coater, or an adhesive application device such as a roll coater may be used.

(3) The second core block layer formation process

Then, as shown in Fig. 6 and Fig. 7, the core block 10 in the state in which the fiber direction is in the up-and-down direction is formed on the upper surface of the first core block layer 21 formed on the mold frame 30 in the longitudinal direction. The core block 10 of the first core block layer 21 is parallel, and the width direction is laminated with respect to the staggered shape in which the core block 10 of the first core block layer 21 is shifted by half, and is arranged in parallel. Thereby, as shown in FIG. 7, the second core block layer 22 is formed on the upper surface of the first core block layer 21. In order to arrange the second core block layer 22 in a staggered manner, the core block 10 on both sides in the width direction of the second core block layer 22 is adjusted to have a width of 1/2.

The heights of the long frame 32 and the short frame 33 of the mold frame 30 are set to be slightly lower than the height of the two core material blocks 10 of the laminate, and the upper surface of the second core block layer 22 is formed to be shorter than the long frame 32 and shorter. The upper portion of the frame 33 is more prominent. Thereby, the core block layers 21 and 22 which are laminated in the state of being accommodated in the mold frame 30 can be pressurized in the subsequent pressurization process.

In the sixth and seventh figures, the core block layers 21 and 22 are all in a parallel state in which the core blocks 10 are extended in the same direction, and are displaced in the width direction to be laminated as a boundary between the core blocks 10. Inconsistent staggered shape, but as shown in Figs. 8 and 9, the core block 10 of the first core block layer 21 on the lower side may be arranged in the orthogonal direction and in a well-like laminated layer. On the other hand, the core block 10 on the upper side is arranged in parallel as the second core block layer 22.

(4) Pressurization process

Then, the first core block layer 21 and the second core material are applied in the thickness direction. The bulk layer 22 is pressurized and joined to each other, whereby the plate-shaped core material 20 in the form shown in Figs. 5(b) and 7 can be obtained. In order to pressurize the upper and lower core block layers 21 and 22, in a state of being laminated on the mold frame 30, as shown in Fig. 10, a plurality of mold frames 30 are overlapped, and the laminate is laminated from above by a suitable pressurizing means. All of the mold frames 30 are pressurized as a whole.

The core block layers 21 and 22 above and below the mold frame 30 are protruded upward from the long frame 22 and the short frame 23 by the upper first core block layer 21, and the amount of protrusion is compressed as a compression amount. Thereby, the upper and lower core block bodies 10 are pressed against each other by the adhesive 25, and the upper and lower core block layers 21 and 22 are joined to each other to form the upper and lower plate-shaped core members 20. The amount of compression is, for example, about 1 mm, whereby the thickness of the core material 20 is approximately twice the thickness of the core block 10, that is, about 50 mm in the case of the above-described size example, and the entire core material 20 has a width of, for example, 900 mm. The length is 2000mm and the thickness is 50mm.

[2] Manufacturing method of non-combustible heat insulation board

When a plurality of core materials 20 are produced by the above process, the non-combustible heat insulation panel in which the steel sheets 40 are fixedly attached to both sides of the core material 20 is manufactured by the board manufacturing apparatus shown in FIG.

In the plate manufacturing apparatus shown in Fig. 11, the input portion 51a of the conveyance path that is conveyed by the drum conveyor 51 sequentially feeds the core material in the direction in which the longitudinal direction is indicated by the arrow F. 20 is put into the production line 50, and the core material 20 is intermittently conveyed by the cylindrical pusher 52. Then, in the intermediate portion of the production line 50, the steel sheets 40 disposed above and below are fixedly attached to the front and back surfaces of the core member 20, respectively.

The upper and lower steel plates 40 are self-assembled steel plates placed above the input portion 51a. The roller 40A is sent to the downstream side of the production line 50, and is guided to the upper and lower sides of the core material 20 by the guide roller 53. From here, the core material 20 is transported together with the steel sheet 40 by the upper and lower transport rollers 54 in a state of being sandwiched between the upper and lower steel sheets 40. During the transport, the steel sheet 40 is opposed to the front surface of the core material 20. It is gradually attached to the rear from the front. Further, the width of the steel sheet 40 is substantially the same as the width of the core material 20, and is adhered to the entire front and back surfaces of the core material 20 by an adhesive applied to the core material 20 or the steel sheet 40.

When the core material 20 is sandwiched by the upper and lower steel sheets 40, the steel sheet 40 is fixedly attached to the core material 20, and the plurality of core materials 20 are transported one by one from the rear by the pusher 52, and are formed as the front end of the core material 20 on the rear side. The surface is in contact with the rear end surface of the core material 20 on the front side, whereby the steel sheet 40 can be fixedly attached to the front and back surfaces of the core material 20 without causing a gap between the core materials 20. Thereby, the plate material 26 of the long length of the steel plate 40 is fixed to the front and back surfaces of the core material 20 to be connected.

The plate material 26 to which the steel sheet 40 is fixedly attached to the front and back surfaces of the joined core material 20 is transported to the cut region. Then, at the time when the required length is transported, the non-combustible heat insulating panel 27 of the desired length is cut by the cutting means 55 provided in the cut-off area. By continuously performing the above operations, a plurality of non-combustible heat insulating panels 27 of a desired length can be continuously obtained.

[3] The effect of the implementation

According to the core material forming method of the non-combustible heat insulating sheet of the embodiment, the second core block layer 22 is laminated on the first core block layer 21, and the core block layers 21 and 22 are pressurized in the thickness direction. Then, bonding is performed, thereby forming the core material 20. The core material 20 is formed into a plate shape by bonding the laminated core material blocks 10 to each other with the adhesive 25 so that the respective core material blocks 10 do not The discrete portions are formed into a plate shape. Thereby, the operation can be easily performed and easily transferred to the next manufacturing process of the non-combustible heat insulation panel having the steel plate fixing and attaching process.

In the manufacturing process of the non-combustible heat insulation panel, the sheet material 26 constituting the production line 50 can be continuously lengthened, and by cutting the sheet material 26 to a desired length, the non-combustible heat insulation panel of the desired length can be easily obtained. 27. Then, in the obtained non-combustible heat insulating panel 27, the fibers 1a of the core block 10 extend in the thickness direction, so that the strength in the thickness direction can be further increased as compared with the case where the fibers extend in the longitudinal direction, thereby having high rigidity.

Moreover, the raw material of the core block 10 is the asbestos raw material slat 1, but the raw material slat as the heat insulating material is not limited to asbestos. In the present invention, as long as the extending direction of the fiber extends along the direction along one side, Ready to use. In addition, the size of the asbestos raw material strip 1, the core material block, and the core material is only an example, and these dimensions can be determined in accordance with design requirements and the like.
