Description

[Detailed Description of the Invention] The present invention relates to a heat-insulating sound-absorbing board made of glass fiber, particularly to a heat-insulating sound-absorbing board made of glass fiber for interior use such as indoor walls or ceilings.

BACKGROUND ART Conventionally, as a sound absorbing board made of fiber, a glass fiber felt is known, in which glass fibers are bonded to each other at their intersections using a small amount of phenol resin or urea resin as an adhesive. This glass fiber felt is usually formed into a cotton-like material in order to have heat-insulating and sound-absorbing properties. Therefore, it is not used as is for indoor interior decoration, and is usually used as a primary material.
As shown in the figure, the surface of the glass fiber felt 6 is wrapped with a surface woven fabric 7 such as a glass fiber woven fabric.

This is because if the surface of the glass fiber felt is exposed on the inner wall, there is a risk that the human body will be injured by the glass fibers when the human body comes into contact with the felt. However, glass fiber felt, which is made by wrapping glass fiber woven cloth etc. in this way, has problems such as dimensional errors between the glass fiber felt and the surface woven cloth, and variations in elastic properties caused by the density distribution of the glass fiber felt, etc. shape of the part,
In particular, irregularities in external dimensions occurred. These irregularities in the peripheral shape are due to poor installation of the heat-insulating sound-absorbing board and the mounting member when installing the heat-insulating sound-absorbing board, and also due to the gap between two heat-insulating sound-absorbing boards that are placed next to each other when installing a large number of heat-insulating sound-absorbing boards in a fixed direction. This caused the appearance of the heat-insulating and sound-absorbing board wall to be poor due to the formation of irregular spaces.

The object of the present invention is to eliminate the above-mentioned conventional drawbacks and to provide a heat-insulating sound-absorbing board made of glass fiber with uniform dimensions and shapes.

In the present invention, at least one side of a plate-shaped glass fiber felt 1 that is formed into a felt shape without woven glass fibers and has two substantially flat surfaces is provided with a thickness that is approximately equal to the thickness of the glass fiber felt 1. Shape retaining piece 3 that is applied to the side edge of glass fiber felt 1 in width
a, and a positioning method 3b for applying to one side of the glass fiber felt integrally formed with the shape-retaining piece 3a; a paper member having a thickness of 1 mm to 5 mm; a metal foil having a thickness of 0.5 mm to 1 mm; and a metal foil having a thickness of 0.5 mm. A shape-retaining member 3 made of a plastic member with a diameter of 3 mm to 3 mm is fixed, and at least one surface of the glass fiber felt with the shape-retaining member 3 is covered with a woven fabric.

Embodiments of the present invention will be described with reference to the drawings. Second
In the figure, glass fiber felt 1 has a thickness of 5 to 25 mm and has a density of 80 to 200 kg per cubic meter.
(as an example, 96 kg/m ³ and 12 mm thick glass fiber felt). Here, a large number of glass fibers constituting the felt 1 are fixed to each other with resin at their intersection points, and have heat-insulating and sound-absorbing properties. This glass fiber felt 1 is cut into arbitrary sizes (for example, width 415 mm and length 2430 mm). Here, in order to protect the shape of the glass fiber heat-insulating and sound-absorbing board, shape-retaining members 3 (for example, 1.2 mm thick cardboard, 0.1 mm thick aluminum foil, 2 mm thick
(made of thick plastic, for example, having a length of 2,430 mm) are attached to two sides of opposing glass fiber felt 1 over almost the entire width using an elastic adhesive (for example, styrene-butadiene rubber). Fix it. Here, the shape-retaining member 3 is made up of a shape-retaining piece 3a and a positioning piece 3b, and the height of the shape-retaining piece 3a is the same as the thickness of the felt 1 for the purpose of protecting the shape of the peripheral part of the glass fiber heat-insulating and sound-absorbing plate. are formed at approximately the same height.

In addition, the positioning piece 3b is provided at the end of the shape-retaining piece 3a in a direction perpendicular to the shape-retaining piece 3a, for the purpose of improving the strength of the shape-retaining member 3 and determining the relative position of the glass fiber felt 1 and the shape-retaining piece 3a. They are attached as one body so that they intersect. The L-shaped cross-sectional shape retaining member 3 is determined by strength conditions depending on its material. For example, in the case of paper parts, 1 to 5
mm, metal foil 0.05~1mm, plastic 0.5~3mm
It is. The shape retaining member 3 has a shape retaining piece 3a at the thickness position of the glass fiber felt and a positioning piece 3b.
is fixed as a glass fiber heat-insulating and sound-absorbing board on the back side. Here, the positioning piece 3b can be attached to the surface as a heat-insulating and sound-absorbing board made of glass fiber, but in such a case, when viewed as a heat-insulating and sound-absorbing board made of glass fiber, the appearance of the positioning piece 3b through the surface woven fabric is is observed, and when attaching the same glass fiber heat-insulating sound-absorbing board to the mounting member, the mounting strength is improved when the positioning piece 3b is attached to the back side of the heat-insulating sound-absorbing board compared to when it is in the opposite position. Because there are many
It is preferable to attach it to the back side. Here, the length of the positioning piece 3b may be approximately the same height as the shape-retaining piece 3a (for example, the height of the shape-retaining piece 3a is 12 mm, and the height of the positioning piece 3b is 10 mm). Then, a woven fabric 2 made of glass cloth or organic fiber etc.
(for example, a glass cloth with a width of 480 mm and a length of 2430 mm) and the surface of the glass fiber felt 1 with the shape-retaining member 3 are sprayed with an elastic adhesive (for example, styrene-butadiene rubber), and the woven cloth 2 is applied to the surface of the felt. After combining the two coated surfaces so as to cover them and bring them together, the two coated surfaces are bonded and solidified using a pressure roller. Here, the surface woven fabric 2 is bonded to the back surface of the glass fiber heat-insulating sound absorbing plate 4, the back surface of the positioning piece 3b, and the back surface of the glass fiber felt 1.

The glass fiber heat-insulating sound-absorbing board manufactured in this way has the shape-retaining member 3 which has a harder elasticity than the elasticity of glass fiber felt, so the glass fiber heat-insulating sound-absorbing board covered with the woven fabric is The peripheral shape can be defined without being affected by the density distribution of the glass fiber felt. Therefore, it is possible to improve the mounting accuracy of the heat-insulating sound-absorbing board and its mounting member, and it is also possible to improve appearance defects such as irregular gaps when two heat-insulating sound-absorbing boards are arranged side by side.

In addition, the shape-retaining member related to the present invention has a structurally strong shape such as an L-shaped cross section, so it can be easily cut with scissors or a cutter, since it has sufficient strength even with materials that do not have much rigidity. The member can be formed from a material that is easily cut by means of the above-mentioned method. Therefore, the glass fiber heat-insulating sound-absorbing board of the present invention is easy to cut, and the glass fiber heat-insulating sound-absorbing board has a small increase in weight. The fact that it is easy to cut indicates the advantage that the shape of the heat-insulating sound-absorbing board can be easily changed in accordance with the shape of the mounting position of the heat-insulating sound-absorbing board at the work site.
Moreover, the fact that there is almost no increase in weight compared to conventional glass fiber heat-insulating and sound-absorbing boards has the advantage that conventional heat-insulating and sound-absorbing board fixtures can be used as they are without any mechanical reinforcement. In addition, by devising the shape of the shape-retaining member in advance and manufacturing it, even if the peripheral shape of the heat-insulating sound-absorbing plate is very complex, it can be manufactured with high precision so that there are no gaps.

Here, in the above embodiment, the surface woven fabric 2 was directly attached to the glass fiber felt 1, but a base member 5 (glass paper, thickness 0.1 mm to 2 mm) may be attached in the same manner as in the previous embodiment (for example, as shown in FIG. 3).

Attaching the base member 5 here has the advantage of making the surface of the glass fiber sound absorbing board more flat,
It also has the advantage of preventing the glass fibers in the felt from penetrating the surface fabric and being exposed to the outside. Further, in the above embodiment, the shape retaining members 3 were attached to the two opposing long sides of the glass fiber felt 1 (as shown in FIGS. 2 and 4), but the shape maintaining members 3 were attached to the four sides of the glass fiber felt 1. A shape retaining member may be attached to each side (for example, as shown in FIG. 5), or a shape retaining member may be attached to one side of the glass fiber felt 1.

Even when attached to one side, the same effect as described above can be obtained by attaching the glass fiber heat-insulating and sound-absorbing plate so that the sides on which the shape-retaining member is attached are in contact with each other. (For example, FIG. 6) Also, the shape of the shape-retaining member 3 is not limited to the L-shaped cross section as in the above embodiment, but even if the shape retaining member 3 has a curvature in cross section (for example, FIG. 7). It does not matter if it is in the shape of a square (for example, Fig. 8). Here, when a shape retaining member 3 having a curvature shape in cross section is attached,
It is possible to obtain a glass fiber heat insulating board having rounded edges with a constant curvature, which is normally impossible to achieve. In addition, when the shape retaining member 3 having a U-shaped cross section is attached, there is an advantage that the strength of the glass fiber heat-insulating sound absorbing board is improved by improving the strength of the shape retaining member 3, and the peripheral shape of the glass fiber sound absorbing board is more secure. You will have the advantage of becoming a real person. Further, by shaping the shape retaining member 3 in a shape based on a certain rule in the length direction, it becomes possible to perform combination construction in which the joints between the heat-insulating and sound-absorbing plates are changed. (For example, Figure 9)
