It is preferable that a plurality of the members are assembled in the transverse direction or the longitudinal direction by the protrusion and the concave structure formed along the outside of the finishing member of the sandwich panel having such a structure. In this case, the polymer resin foam for joining the sandwich panel It is preferred that the adhesive composition or the foamed adhesive pad be located.

The polymeric resin foamable adhesive composition for sandwich panel bonding may be formed by coating or spraying in the form of a composition. The polymeric resin foamable adhesive composition for bonding the sandwich panel may be subjected to ordinary molding to give a fireproofing layer having a thickness of 1 to 5 mm It is also possible to apply to the joint site in the form of foam adhesive pads, which reinforce the bonding forces of the different sandwich panels within the asperity structure formed along the closure member 50.

Thus, it is possible to effectively prevent the fire from spreading by preventing the flame from being generated or moving through the gap formed in the panel assembling part, and even when the fire is not generated, the fire- Durability (e.g., compressive strength and the like) that satisfies the performance of the battery can be improved.

Therefore, in order to secure the fire resistance at the time of construction of the existing sandwich panel, the present invention is characterized in that a ceragewall which is difficult to be installed in the panel assembly portion is inserted at a thickness of 12.5 mm or an aluminum rivet is applied to both sides of the assembly portion at an interval of about 8 cm It is possible to effectively overcome the limitation of preventing the diffusion of the flame through the minute gap or space generated in the assembly part in case of fire.

In order to improve the strength of the refractory foamed bonding pad, the filler is preferably contained in an amount of 13 to 45 parts by weight based on 100 parts by weight of the high molecular weight polymer. In order to improve the dispersibility of the filler, the degree of polymerization is preferably 3,000 to 6,000, Or more of the polyvinyl alcohol dispersion aid having a degree of saponification of 3 to 6 parts by weight based on 100 parts by weight of the high molecular weight polymer.

Further, in the present invention, in addition to the acrylic polymer, a urethane polymer obtained by including 100 parts by weight of a urethane urea resin obtained by reacting an urethane prepolymer having an isocyanate group at the terminal thereof with an amino compound and 0.5 to 10 parts by weight of a curing agent may be used. It is also possible to use a mixture of an acrylic polymer and a urethane polymer.

When the amount of the filler used is less than 13 parts by weight, the degree of improvement in the compressive strength of the refractory foam adhesive composition or the refractory foam adhesive pad is insignificant. When the filler content exceeds 45 parts by weight, Uniform dispersion in the refractory foamed bonding pads is difficult, resulting in a problem that the compressive strength becomes nonuniform depending on the position.

Even if polyvinyl alcohol as a dispersing aid is used for more uniform dispersion of the pores, when the amount of the pores is more than 45 parts by weight, the function of the dispersing aid can not be effectively exerted.

Compressive strength was measured according to KS F 2519: 2000 and KS F 2518: 2005 for the above Examples and Comparative Examples, and heat resistance was also measured.

In order to measure the heat resistance, the refractory foamed bonding pads of each of the comparative examples and the examples were crushed by a crusher, and the crushed material was put into a Labo plastomill. The crushed material was melted and kneaded at 200 ° C and taken out immediately. . The obtained plate-like molded article was heated in a hot press at 220 占 폚 for 40 minutes and then cooled with a cooling press to obtain a heat resistance test sample. The spectroscopic color system SD6000 manufactured by Nippon Seimei Kogyo Co., Ltd. was used to calculate? E for each of the standard white plates. At this time, the smaller ΔE, the higher the heat resistance.

As can be seen from the results of Table 1, it was found that the compression strength and heat resistance of the refractory foamed adhesive pad were improved as the mixing ratio of the particle graphite increased, and the physical properties of the refractory foamed adhesive pad of the present invention were as thin as 1.5 to 3 mm Despite the thickness, it means that it improves the convenience of installation and the heat resistance is excellent, and it is effective to prevent the spread of fire by foaming in case of fire.

In order to confirm the effect of addition of the dispersing aid, the compressive strength and heat resistance were measured in the same manner as in Example 5, in which the ratio of graphite in the particle chain was the highest, while varying the amount of the dispersing aid. Respectively.
