The present invention relates to a PC sound board 100 comprising a PC material or a PC material, and as a means for supplementing the shortcomings of the conventional PC sound board, as shown in FIG. 1, the PC sound board 100 is divided into three parts. and limit it. The reason for limitation is that it was possible to obtain a result in which maintenance can be performed conveniently while using the PC soundproofing board 100 used for the transparent soundproofing wall most effectively as a result of long research, not simply the obtained result.

The divided PC sound insulation board 100 is composed of an intermediate panel 200 , a PC first separation panel 300 , and a PC second separation panel 310 . At this time, when the PC sound insulation board 100 is divided and manufactured, the middle panel 200 is the thickest, and the PC first separation panel 300 and the PC second separation panel 310 are smaller than the intermediate panel 200 and have the same thickness. It is required to have

When replacing the PC sound insulation board 100, the intermediate panel 200 according to the present invention is not replaced, but only the PC first separation panel 300 and the PC second separation panel 310 installed on the front and rear sides are separated, and a new This is because the PC first separation panel and the PC second separation panel are replaced.

Figure 3 is a first embodiment showing the configuration of the PC sound insulation board according to the present invention;

In general, the PC soundproofing board 100 used for the transparent soundproofing wall is composed of 10T. Therefore, based on this 10T, in the present invention, as shown in (a) (b) of FIG. 3 , both the PC first separation panel 300 and the PC second separation panel 310 are made of a PC material, and when manufacturing It was made to have a thickness of 2T by UV coextrusion. The standard of 2T is to satisfy the accelerated weather resistance performance of the highway construction material quality standard, and the PC plate that meets this standard must be made by UV co-extrusion because 2T is the thinnest product.

In Fig. 3 (a), the intermediate panel is made of a PC material, and is composed of a 6T PC intermediate panel 210 . 2T PC first separation panel 300 and PC second separation panel 310 installed on the front and rear sides of the PC intermediate panel 210, respectively, were made of the same PC material. In this way, when the PC first separation panel 300 and the PC second separation panel 310 are laminated and used on the front and rear surfaces of the PC intermediate panel 210, respectively, when yellowing occurs due to ultraviolet rays, the PC intermediate panel located in the middle ( 210) does not cause yellowing, and yellowing occurs on the side of the PC first separating panel 300 and the PC second separating panel 310 located on the same side. At this time, the PC middle panel 210 is not replaced, and only the PC first separation panel 300 and the PC second separation panel 310 in which the macular phenomenon occurs are simply replaced.

On the other hand, as in Fig. 3 (a), the PC sound insulation board is not limited to all made of PC material, and if the desired purpose can be achieved, the material of the intermediate panel is changed to a different material as in Fig. 3 (b). Can be used.

According to (b) in FIG. 3, it is composed of a 6T glass panel 220 made of a tempered glass material, and a PC first separation panel 300 having a 2T thickness of PC material on the front and rear surfaces of the glass panel 220. and PC second separation panel 310 were applied to allow simultaneous use of tempered glass material and PC material.

In this way, if the PC first separation panel 300 and the PC second separation panel 310 are laminated on the front and rear surfaces of the glass panel 220, respectively, and yellowing occurs due to ultraviolet rays, the glass panel 220 is not replaced. Instead, it is only necessary to simply replace the PC first separation panel 300 and the PC second separation panel 310 in which the macular phenomenon occurs, and the stacked between the PC first separation panel 300 and the PC second separation panel 310 is The glass panel 220 has the effect of preventing damage to scattering and the like.

As described above, the ratio of the PC first separation panel 300, the PC intermediate panel 210 and the glass panel 220, and the PC second separation panel 310 is 2:6:2, and the PC first separation panel 300 ), PC middle panel 210, PC second separation panel 310 or PC first separation panel 300, glass panel 210, PC second separation panel 310 was satisfied when used in lamination.

As described above, the present invention having a triple stacking structure is insulated from each other so that it is advantageous for vibration transmission due to vehicle noise, and the sound transmission loss performance can be increased.

Vibration isolation means to block vibration energy by changing the impedance of the transmission medium when transmitting vibration energy, and to block by generating reflected energy. When a vibration wave propagates to another material, it is incident, reflected, and transmitted, and when the density difference of the medium is large, the vibration insulation effect is large as follows.

<Example 2>

Figure 4 is a second embodiment showing another configuration of the PC sound insulation board according to the present invention.

2 to 3, 10T has been described as a reference, but when a PC soundproofing board of 8T is used other than 10T, the PC soundproofing board 100 is divided into three parts, and the PC first separating panel 300 and the PC second separating panel ( 310) is manufactured in 2T, there is no change. However, when manufacturing on the basis of 8T, as shown in FIG. 4 , the intermediate panel 200 may be manufactured in 4T and the ratio of 2:4:2 may be configured and used.

On the other hand, looking at the effect of the PC sound insulation board of the laminated structure in the present invention on the yellowing phenomenon is as follows.

- Confirmation of yellowing through accelerated weathering test for laminated samples

- Laminated samples were each 1T, and 5 PCs were prepared, and these were sequentially laminated.

- For the measurement of yellowing, the degree of yellowing was measured through an accelerated weathering test.

- In the accelerated weathering test, ultraviolet rays were exposed to the sample according to KS M 4892-3, and the degree of yellowing of the sample was measured according to the exposure time.

- In general, for the accelerated weather resistance test on the transparent soundproof wall, UV exposure was performed for 1,500 hours, and for the laminated sample plate, general PC products were used, not UV co-extrusion, which has strong accelerated weather resistance.

UV exposure sequence Yellowness (ΔYI) first sample 12(-) 2nd sample 5(-) 3rd sample 2.3(-) 4th sample 0.2(-) 5th sample 0.1(-)

As shown in Table 2, the yellowing degree (ΔYI) of the first sample stacked on the top among the stacked samples was confirmed to be 12 (-), the second sample was 5 (-), and the last sample was 0.1 (-). became Therefore, it was confirmed that the first sample stacked on top had the highest degree of yellowing, and the fifth sample stacked last had almost no degree of yellowing.

As shown in Table 2, a general PC without UV coating was tested to cause yellowing to occur quickly, but when a UV co-extruded sample was used, the UV co-extruded sample itself had less yellowing shape and thus had a laminated structure PC according to the present invention The yellowing phenomenon does not occur in the PC intermediate panel 210 of the sound insulation board 100 .

For this purpose, the results of testing the general PC sample and the UV co-extruded sample are as follows.

As shown in Table 3, when the accelerated weather resistance of the general product, which is a PC sample of 2T or more, and the UV co-extrusion-treated sample according to the present invention was compared for 1000 hours, it was found that the degree of yellowing was less than 10(-) than that of the general PC sample.

Based on Table 3, a 6T or 4T PC intermediate panel 210 is laminated between the PC first separating panel 300 and the PC second separating panel 310 made of 2T, and the degree of yellowing is as follows. .

- Duration of yellowing degree: 200 h

UV exposure sequence Yellowness 200 h) (ΔYI) PC first separation panel 1.3(-) PC middle panel 0.2(-) or less

As shown in Table 4, it was confirmed that a large number of PC first separation panels, which are samples with a degree of yellowing stacked on top, occurred, and there was almost no yellowing on the PC intermediate panel side.

Therefore, when the PC first separation panel 300 and the PC second separation panel 310 are laminated on the front and rear surfaces of the UV co-extruded PC intermediate panel 210 of the present invention, basically, the PC intermediate panel 210 is used. The yellowing phenomenon on the side is not prevented, and it is enough to replace the PC first separation panel 300 or the PC second separation panel 310 in which the yellowing phenomenon has occurred.
