2. Description of the Related Art In fixing a speaker net made of polyvinyl chloride or the like as described above, various double-sided adhesive tapes (hereinafter referred to as "double-sided adhesive tapes" prepared by applying an adhesive to both sides of a support formed of a flexible material. Conventional double-sided adhesive tape ") has been used. However, the porosity of the adherend speaker net is about 58% as an example,
Adhesive strength of conventional double-sided adhesive tape is 1,000g / 20m
Since it is about m or less, it is hard to say that these conventional double-sided pressure-sensitive adhesive tapes can surely fix the speaker net. There is also a problem that the adhesive exposed in the openings of the mesh in the speaker net looks shiny. Furthermore, since the pressure-sensitive adhesive in the conventional double-sided pressure-sensitive adhesive tape has a relatively high adhesive strength even at room temperature, there is a drawback that dust and dirt are easily attached to the pressure-sensitive adhesive exposed in the openings of the mesh of the speaker net.

Therefore, in order to solve such a problem in the conventional double-sided adhesive tape, as shown in FIG. 4, a black polyester film is used as the support 1 and the surface of the support 1 on the side of the speaker net 2 is used. 3 is coated with a synthetic rubber foamable hot melt adhesive 4 and an acrylic pressure-sensitive adhesive 7 is applied to the opposite surface 5 (cabinet 6 side) (hereinafter referred to as a double-sided adhesive tape "Improved double-sided adhesive tape") is provided. When this improved double-sided pressure-sensitive adhesive tape is heated to a temperature of about 120 ° C. and a pressure of about 2 to 3 kgf / cm 2 is applied for several tens of seconds, the foamable hot-melt pressure-sensitive adhesive 4 foams as shown in FIG. Then, it bites into the openings 8 of the mesh in the speaker net 2 and exerts an anchoring effect to increase the adhesive force, and the foamed surface 9 of the foamable hot-melt adhesive 4 becomes uneven so that the mesh in the speaker net 2 becomes uneven. The surface of the pressure-sensitive adhesive exposed in the openings 8 is a matte surface that does not shine. In addition, foamable hot melt adhesive 4
Since the adhesive strength is low at room temperature, it is possible to prevent the adhesion of dust and dust to the adhesive exposed in the mesh openings 8 of the speaker net 2 due to the adhesive strength.

However, in the above-mentioned improved double-sided adhesive tape, when the speaker net 2 is fixed to the front end of the cabinet 6, it must be pressurized in a state of being heated to about 120 ° C. as described above. However, when heated to such a temperature, the polyester film constituting the support 1 reaches the limit in terms of heat resistance, so that the tape cannot be stamped until the entire tape is sufficiently cooled. Therefore, there arises a problem that the workability in fixing the speaker net 2 is poor. Further, the support 1 of the polyester film bent and digging into the mesh openings 8 of the speaker net 2 during heating and pressurizing tends to return to its original straight state after cooling. There is also a drawback that On the other hand, if the heating and pressurization at the time of fixing are insufficient, most of the performance of the double-sided adhesive tape will not be exhibited. Further, the above-mentioned improved double-sided pressure-sensitive adhesive tape has a problem that the material is expensive and the cost is high. The present invention has been made to solve not only the above problems in the conventional double-sided pressure-sensitive adhesive tape but also the above-mentioned problems in the improved double-sided pressure-sensitive adhesive tape.

[Operation] Since the heat-activatable pressure-sensitive adhesive coated on the surface of the support on the speaker net side has a low adhesive strength at room temperature,
There is no risk of dust or dirt adhering to the adhesive exposed in the mesh openings of the speaker net. Further, since the aluminum foil is used as the support, even when roll pressure is applied to the double-sided adhesive tape for fixing the speaker net at room temperature during fixing, the support bends and bites into the mesh openings of the speaker net, This state is maintained (see FIG. 2). Therefore, even when the roll pressure is applied at room temperature, the double-sided adhesive tape for fixing the speaker net exerts a sufficient anchoring effect on the speaker net and has an adhesive force of about 1.5 kg / 20 mm. Further, the aluminum foil as the support is easily bent even when pressed with a small force. When roll pressure is applied in a state of being heated to 80 to 120 ° C., the adhesive force of the double-sided adhesive tape for fixing the speaker net, which has a heat-acting pressure-sensitive adhesive applied to the surface of the support on the speaker net side, is 3 kg / Increase to about 20 mm. In this case, since the support is an aluminum foil, it is needless to say that there is no problem even if it is heated to about 120 ° C. and the workability in fixing the speaker net is extremely good, and it is bent as described above. It is also clear that the aluminum foil support does not return to its original state after cooling. Furthermore, since the double-sided adhesive tape for fixing the speaker net of the present invention has the matting agent sprinkled on the surface of the heat-activatable pressure-sensitive adhesive, the double-sided adhesive tape enters the surface exposed in the mesh openings of the speaker net. As a result of diffuse reflection of light, the surface becomes a matte surface that does not shine.

Embodiments of the present invention will now be described with reference to the accompanying drawings. Reference numeral 11 is a support made of aluminum foil. The thickness of the support 11 is, for example, 20 μm.
It is about m. A surface 12 of the support 11 on the side of the speaker net 2 is coated with a heat-activatable pressure-sensitive adhesive 13, and the surface of the heat-activatable pressure-sensitive adhesive 13 is provided with a matting agent 14, 1
Disperse 4 ... The matting agent 14, 14, ... Is preferably a gray color matching the color of the speaker net 2,
For example, a mixture of black carbon black and white titanium oxide or calcium carbonate is used. The particle size of these pigments is, for example, about 5 to 40 μm,
It is desirable to use one having a small particle size that does not cause clogging of the nozzle for spraying the pigment. An acrylic pressure-sensitive adhesive 16 is applied to the surface 15 of the support 11 on the opposite side (cabinet 6 side) as an example. Release liners 17 and 18 are provided on both adhesive surfaces of the double-sided adhesive tape for fixing the speaker net. Reference numeral 20 in FIG. 3 is a speaker.

As described above, the double-sided adhesive tape for fixing the speaker net according to the present invention can be surely fixed to the cabinet with a strong adhesive force backed by the anchor effect which does not deteriorate after cooling the speaker net. Moreover, there is no fear that dust or dirt will adhere to the surface of the adhesive exposed in the openings of the mesh of the speaker net. Furthermore, since the matte treatment is performed, the surface of the adhesive exposed in the openings of the mesh of the speaker net does not shine. As described above, since the support is an aluminum foil having excellent heat resistance, there is no problem in workability in fixing the speaker net.
