As can be seen from Table 1, the sound insulating material of ethyl vinyl acetate material in the commercial distribution of Examples 1, 2, and Comparative Example 1 of the present invention was found to be satisfactory in use by satisfying the criteria of the dynamic elastic modulus items. The sound insulation material of the styrofoam material of Comparative Example 2 was found to have a problem in use because the dimension stability property items did not meet the standard values;

In particular, the sound insulation material of the ethyl vinyl acetate material of Comparative Example 1 is a defect due to the sound insulation material is torn due to the load transmitted from the bubble concrete layer, the finishing mortar layer, the floor decoration layer which is the floor surface of the building installed on the sound insulation material, It turned out to be a problem in load bearing capacity,

In the sound insulation material of the styrofoam material of Comparative Example 2, the sound insulation material was badly damaged by the load transmitted from the foam concrete layer, the finishing mortar layer, and the floor decoration layer, which is the floor surface of the building installed on the sound insulation material. It turns out to be a significant problem.

In addition, it was found that Examples 1 and 2 of the configuration of the present invention were significantly superior in terms of dynamic modulus, dimensional stability, and load bearing properties than Comparative Examples 1 and 2;

Embodiments 1 and 2 are bonded to the floor slab layer, which is the building floor, and the sound insulating material and the sound insulating member 1 are stacked and installed on the top of the sound insulating member 2, so Unflowed from the top, it has been found to greatly improve workability,

In Comparative Examples 1 and 2, it was found that workability was significantly reduced due to the sound insulation material being directly deposited on the floor slab layer, which is the floor of the building, because the sound insulation material is partially separated from the flow and construction sites at the top of the floor slab layer.

As shown in Table 3, the sound insulation performance of the light and heavy sound of the sound insulating material of Example 1 and Example 2 of the present invention was found to be remarkably superior to Comparative Examples 1,2;

In particular, the sound insulation performance of the light weight and heavy sound of the soundproofing materials of Examples 1 and 2 was found to be the best first class;

The sound insulation material which consists only of the sound insulation base material of the ethylvinyl acetate material which is a commercial distribution of the comparative example 1 was proved that sound insulation quality fell to light grade 4th grade, heavy sound grade 4th grade,

The sound insulation material consisting only of the sound insulation material of the styrofoam material of the comparative example 2 was found to have failed the soundproofing result of the light weight and the heavy sound to grade 4 and grade outside, and it turned out that the sound insulation performance as a sound insulation material has a problem.
