る。 As a ghost prevention measure for VHF and UHF televisions, it has been proposed to attach sintered ferromagnetic ferrite plates in the form of tiles to the walls of high-rise buildings. However, radio waves with shorter wavelengths such as SHF and EHF (more than 1 GHz...for example, 9 GHz and wavelength 3)
cm), the ferrite sintered body loses its effectiveness, so conventionally, the ferrite sintered body is first crushed and dispersed in a polymer binder to form a paint, paste, or putty, and then applied to specified areas on the wall. It was applied to. However, in order to have sufficient absorption effect for radio waves such as 9GHz, the coating thickness must be adjusted.
It is necessary to set it at around 1.2 to 3.5 mm. However, when ordinary paints are used, the thickness of the coating film is only on the order of several tens of microns. On the other hand, there is no effective method for applying paste or putty to a constant thickness, and the thickness tends to fluctuate. Among the methods tried by the present inventor, for example, the method of extrusion molding a sheet of rubber with ferrite powder dispersed in it and pasting it on the wall surface resulted in a large amount of waste due to the cutting of trees before construction. Also, it took time to bond. I also tried applying paste or putty using the net as a thickness gauge after pasting the net on the wall.
There was no way to apply the net evenly to the wall. Furthermore, since the non-magnetic net occupies a large volume, radio waves are reflected, reducing the effectiveness of the absorber.
従つて、本発明は電波吸収体を所定の壁面に、
一様に且つ効率的に形成しうる方法を提供するこ

The object is to provide a method that can be formed uniformly and efficiently.

間のない電波吸収体が得られる。 In order to form a radio wave absorption wall having good absorption properties especially for radio waves on the order of GHz,
A high viscosity paste or putty (hereinafter referred to as putty) made of resin or rubber (e.g. epoxy, chloroprene) containing ferromagnetic ferrite powder is applied to a predetermined surface of a building (e.g. around a parabolic antenna or radar antenna). When applying the putty to the area that causes the ferrite powder, first, putty containing ferrite powder is applied to the surface in a plurality of islands to have a constant thickness. Even if there are gaps between the islands of constant thickness of the putty, if they are properly defined according to the wavelength of the radio waves, the radio wave absorption characteristics will hardly deteriorate. Islands of constant thickness can be formed by various methods. For example, fixed-thickness strips or fixed-thickness frames are adhered to predetermined locations on the surface of a building at regular intervals, and these are used as rulers to apply the putty containing ferrite powder to the surface of the structure. These constant-thickness strips or constant-thickness frames may be peeled off later. Alternatively, it is also conceivable to apply the ferrite powder-containing putty using a trowel having recesses or reliefs of constant thickness. Another method is to apply the same putty as the putty islands to the constant thickness strips described above using the same trowel as just mentioned, and use these constant thickness strips as rulers to apply the putty islands and fill the gaps. It is possible to obtain a radio wave absorber that is

きる。 It is preferable in terms of radio wave absorption characteristics that the gaps between islands of constant thickness of putty be completely filled with the same putty. In this case, the putty containing ferrite powder is applied to the gap using the thickness of the island of constant thickness of the putty as a ruler. For example, fixed-thickness strips or fixed-thickness frames are temporarily attached to the construction surface of a building at a predetermined gap, then ferrite-containing putty is applied to the construction surface using these fixed-thickness frames or strips as a ruler, and then fixed-thickness frames are applied to the construction surface. Or peel off the strips. Using the islands of putty thus formed with a constant thickness as a ruler, putty is applied between the islands to obtain a radio wave absorber having a uniform thickness throughout. Alternatively, there is a method in which islands of putty of a constant thickness are formed using a trowel having recesses or reliefs of a constant thickness, and the same putty is applied between these islands of putty as a ruler. In this way, a radio wave absorber having a constant thickness can be obtained, and a good radio wave absorbing surface can be constructed.

Figures 1-3 first illustrate three examples of constant thickness strips for use in carrying out the method of the invention. Referring to FIG. 1, a constant thickness strip 1 is bonded to a flexible plastic strip 2 (polyvinyl chloride, etc.) having a constant thickness d = about 2 to 3 mm and an adhesive layer 3 coated on its back surface. It consists of a release layer 4 that protects the agent layer. This fixed-thickness strip is adhered at predetermined intervals to the surface of a building requiring radio wave absorption, with the release layer 4 removed.

Ｃ）。 Now, referring to Figures 4 and 5, first, as shown in Figure 4A, the constant thickness strip 1 (or 1', 1'') is
is pasted on a predetermined wall surface 8 of the building. Next, putty (for example, consisting of a mixture of 0.5 parts of epoxy resin, 1 part of ferrite powder, and 0.5 parts of talc, and a solvent) is applied to the wall surface 8 using these constant thickness strips 1 as a ruler to form putty islands 9. For example, a method can be considered in which an excessive amount of putty is applied almost uniformly over the entire wall surface using a trowel, and then smoothed with a doctor or the like having a straight edge (FIGS. 4b and 5). The constant thickness strip 1 can be left in place without being peeled off if the adhesive layer 3 on the back side is made of a highly adhesive adhesive. In this case, strip 1
Make the width sufficiently thin so that the radio wave absorption characteristics do not deteriorate. Furthermore, if the adhesive layer 3 is sticky, the constant thickness strip 1 will peel off. Of course, in the case of constant thickness strips 1' and 1'', they will peel off (FIG. 4C).

As for its structure, a structure similar to that of the constant thickness strip shown in FIGS. 1, 2, or 3 may be adopted (however, only the shape is different). In construction, the constant-thickness frame 12 is first fixed to the surface of the structure where power absorption is required, and the putty island 9 is placed in a manner similar to that described in connection with FIG. 4B.

As mentioned above, it is easy to form islands of putty with a constant thickness, which makes the work easier compared to the conventional method of applying putty over the entire surface using a trowel.

され、すぐれた電波吸収体を構成できる。 FIG. 9 then shows a method of forming constant thickness strips in place of the constant thickness strips or frames shown in FIGS. 1, 2, 3 and 7. The constant thickness strip in this case is formed from the same putty as the islands of constant thickness putty. That is, a soldering iron having a recess or relief with a thickness d and a narrow width k is prepared,
Using this, putty is applied directly to the surface of the construction part to form a constant thickness strip 1. Once a plurality of strips of constant thickness are applied to the wall surface at intervals, putty is applied between the strips of constant thickness as a ruler to form islands of putty. In this case, care must be taken to ensure that the hardness of the putty is determined to be sufficient to function as a ruler in an undried state. According to this example,
Since the constant-thickness strip 1 itself is a radio wave absorber, the constant-thickness strip can be used in a state fixed to the building surface together with the island, and can constitute an excellent radio wave absorber.

して連続的に実行できる。 Next, in the examples explained in relation to Figures 1 to 8, there are gaps in the radio wave absorber, but in order to obtain a radio wave absorber with better characteristics, these gaps can be filled with islands of putty of constant thickness. It is best to fill it with the same material. Therefore, in this example, in addition to carrying out the steps corresponding to the steps A to C in FIG. 4 as they are in each of the above examples (excluding the example described in connection with FIG. 9), these steps are performed in the next step. Using the putty island of constant thickness as a ruler, putty 11 is filled into the groove 10 created in the step shown in FIG. 4C using an appropriate trowel. If the putty is selected from those with a sufficiently high consistency, then steps B to D in Figure 4 can be used.
The process corresponding to can be carried out consistently and continuously without the need for a drying step.

According to this example, it is clear that the entire predetermined surface of the building is covered with the radio wave absorber, providing good radio wave absorption characteristics.

特性を有する電波吸収体を得ることができる。 In all of the above examples, drying shrinkage of the putty is inevitable as it dries. Since the magnitude of this drying shrinkage can be predicted, the radio wave absorber produced according to the present invention can have a uniform thickness. However, depending on the application, thickness deviation caused by drying shrinkage may become a problem. It can be. In this case, all the above examples should be modified to set the expected dry thickness of the putty to be thinner than the planned dimensions.
After the putty dries, a resin paint containing ferrite powder (with a dry thickness of several tens of microns per coat) having a viscosity similar to that of ordinary paint is applied to the lower putty layer the required number of times. It is possible to obtain a radio wave absorber having radio wave absorption characteristics of .

The thickness of the second coating is determined by applying the coating thickness for the second time, and it is possible to easily and reliably create a radio wave absorbing wall with a constant thickness.
