Table 6 shows the results of the thermal conductivity test for the adhesive compositions according to Examples 1 to 6 and Comparative Example 1. At this time, the thermal conductivity was measured by a laser scintillation method (ASTM E 1461), and a thermal conductivity measuring instrument was a Linseis XFA 300 device. Each specimen was measured to be 10 mm × 10 mm × 2 mm (width × length × thickness) and measured at 25 ° C. at room temperature.

[Table 6]

Referring to Table 6, according to the test results, the higher the content of the hollow spheres, the lower the thermal conductivity. In Examples 1 to 6, the heat insulating effect was increased to about 20 to 25% The thermal conductivity increased with the addition of powder.

This means that in the case of the interior material for insulation, the content of the micro hollow spheres can be selected and the content of the metal powder can be selectively increased by improving the thermal conductivity.

As can be seen from the above experimental results, it is possible to selectively manufacture the building interior material construction adhesive by using the properties according to the results in a non-heating space requiring heat insulation and a heating space requiring improvement in thermal conductivity.

(1) Basic physical properties (2) Crack prevention effect (3) Noise and vibration improvement effect (4) Heat conduction degree is selectively controlled by thermal conductivity.
