た。2. Description of the Related Art This type of corrugated inorganic fiber board is flexible when it is installed in a curved place, so that it can be mounted in close contact with a curved portion without any gap, so that it has an excellent heat insulating effect and does not increase the bulk density. Nonetheless, that is, despite the reduction in weight, it has excellent characteristics that it has a large compressive strength and a large peel strength without causing delamination as in the conventional inorganic fiber mat. However, this type of Japanese Patent Publication Sho 63-19338, which was previously proposed.
No. 2, Japanese Patent Publication No. 2-6492, Japanese Patent Laid-Open No. 63-270851.
The method disclosed in U.S. Pat. No. 5,968,961 could not be continuously manufactured with the wave height and spacing of the web being constant and the fiber direction being oriented substantially perpendicular to the plane. Therefore, the applicant of the present application discloses in Japanese Patent Application No. 6-74126 a method for producing a corrugated inorganic fiber board, which comprises a pair of folding actuating members for an inorganic fiber web in which resin-attached inorganic fibers are oriented and laminated in layers. A manufacturing method has been proposed in which the inorganic fibers are folded in a zigzag shape by a corrugating machine to orient the inorganic fibers in a vertical direction, and then heated and pressed.

った。However, since the inorganic fiber web is not as thin as the filter paper of an air filter but is relatively thick, even if it is folded in a zigzag shape, as shown in FIG. The inner peripheral surface of the corrugated wave is curved, and a void is generated along the inner peripheral surface of the wave. In addition, since it is necessary to heat and press-mold the corrugated web in order to align it with the desired wave height, the upper part of the wave is pushed vertically downward by the compressive force from above and below, and the lower part of the wave is It is pushed vertically upward, which causes the void to expand in the lateral direction, resulting in an increase in the void space. In the figure, 4'indicates an inorganic fiber web, and 4a 'indicates a void formed on the inner peripheral surface of the corrugated wave. As a result, there is a problem that convection of air occurs due to the size of the void space and the equivalent thermal conductivity deteriorates.

て折り畳むようにしたことを特徴とする。The corrugated inorganic fibrous board of the present invention is, in order to solve the above-mentioned conventional problems, a zigzag-shaped folded inorganic fiber web in which resin-attached inorganic fibers are oriented and laminated in layers. In a corrugated inorganic fiber board in which the inorganic fibers were oriented in the vertical direction by folding, the inorganic fiber web was inclined and folded. In addition, the method for producing an inorganic fiber board of the present invention is a method in which inorganic fiber webs in which resin-attached inorganic fibers are oriented and laminated in layers are zigzag-folded by a corrugating machine composed of a pair of folding actuating members, In the method for producing a corrugated inorganic fiber board in which the fibers are oriented in the vertical direction and then heated and pressed, the inorganic fiber web corrugated by the corrugating machine is supplied to the heating and molding furnace, and the upper side of the heating and molding furnace. By adjusting the speed ratio between the upper perforated belt conveyor and the lower perforated belt conveyor while pressing the inorganic fiber web corrugated with the perforated belt conveyor and the lower perforated belt conveyor to a desired wave height. It is characterized in that the inorganic fiber web is inclined and folded.

Alternatively, it is obtained by spraying, impregnating, dipping or the like a thermoplastic resin such as a polyethylene resin or a polypropylene resin and then suction-depositing it on a perforated belt conveyor of a cotton collecting machine.

きるものであれば特に限定されるものではない。The corrugating machine is composed of a pair of gears rotating in opposite directions, a gear type in which the inorganic fiber web is folded in a zigzag shape at a meshing portion of these gears, and a pair of folding operations for folding operation. A typical example is the Lavoski type in which the inorganic fiber web is folded in a zigzag shape by the folding operation of these folding operation plates, but it is folded by a pair of rolls in which male edges and female edges are arranged. The rotary type is not particularly limited as long as it can be accurately corrugated mechanically.

である。The wave height and wave interval of the corrugating machine are appropriately selected. The wave height is approximately the same as the thickness of the inorganic fiber board, and the wave interval is 5 to 50 mm, preferably 25 to
The thickness of 35 mm is effective in making the most of the characteristics of the corrugated inorganic fiber board.

り所望の波高さと波間隔が得られない。The inorganic fiber web may be supplied to the corrugating machine by a belt conveyor or by dropping by its own weight. When using a belt conveyor, the peripheral speed is preferably 2 to 6 times faster than the peripheral speed of the lower belt conveyor with holes in the heating molding furnace. However, this ratio is determined by the basis weight of the inorganic fiber web, the number of corrugated peaks and the density of the corrugated inorganic fiber plate, and is appropriately selected. If the speed ratio is less than twice, the zigzag-shaped fold is not sufficient, and the desired wave height and wave interval cannot be obtained because the wave can be corrugated only to the extent of folding rather than bending. On the other hand, if it exceeds 6 times, the number of peaks increases and the gaps are compressed so that a sufficient gap cannot be secured and the density becomes high, so that the desired wave height and wave interval cannot be obtained.

Glass paper, glass cloth, felt such as carbon fiber / glass fiber, etc., which has heat resistance and breathability above ℃, acts as a separator between the curved surfaces of the web, and has a degree of freedom after fiber molding. . If the sheet is a hot-melt film such as a hot-melt film that melts into a binder in a heating molding furnace or a thermoplastic resin film such as a hot-melt non-woven fabric, the uncured resin of which the curved surfaces are contained in the web is Since it can be firmly bonded separately from bonding,
It is possible to prevent deterioration of heat insulation performance due to the formation of a gap between the bent surfaces. Further, in this case, a synthetic resin powder such as a thermoplastic resin may be sprayed instead of the film.

熱伝導が良好となる。By adjusting the speed ratio of the belt conveyor, the upper part of the corrugated inorganic fiber web is slanted in an oblique direction, for example, because the speed of the upper perforated belt conveyor is slightly higher than that of the lower perforated belt conveyor. When pressed, the corrugations incline correspondingly, and at the same time, the void shape on the inner peripheral surface of the wave generated by corrugation also inclines to the same angle as the inclination, and is further crushed by the upper and lower belt conveyors to narrow the void space. Become. Therefore, heat transfer due to convection in the void space is suppressed, and the equivalent thermal conductivity can be increased. Further, as compared with the conventional corrugated inorganic fiber board, the slanted corrugation increases the ratio of the fiber orientation perpendicular to the heat transfer direction, thereby improving the heat conduction.

In Comparative Example 1, a corrugated glass fiber plate having the same thickness and the same density as the conventional online-manufactured Example was used, as shown in FIG.

The thermal conductivity is reduced by about 10% and the heat insulation performance is deteriorated. On the other hand, in the example, the void space was crushed and narrowed, and the fiber orientation increased in the direction perpendicular to the heat transfer direction, so that the equivalent thermal conductivity decreased only to about 5%, which is more than that of the comparative example 2. Excellent heat insulation was obtained.
