SYNTHETIC RESIN COMPOSITION, FIRE-PROOF MATERIAL, SEALING MATERIAL, ADHESIVE, AND JOINT STRUCTURE

Abstract

The present invention provides a synthetic resin composition from which a combustion residue produced by combustion is rigid. The synthetic resin composition of the present invention is configured such that the strength of the combustion residue of the composition after combustion in an atmosphere of 800° C. for 20 minutes is 0.5 N/mm.sup.2 or more. Thus, the combustion residue produced by combustion is very rigid. The combustion residue is capable of reliably holding a state where a joint part is filled therewith and clogged even during a fire, preventing flames from passing through a sealing part such as the joint part, and imparting excellent fire-proof performance to a wall part of a building construction.

[0197] A synthetic resin, a mineral, a binder component, an expansion agent, and another additive were uniformly mixed in mixing amounts shown in Tables 1 to 6 using a planetary mixer in a vacuum atmosphere over 60 minutes, to obtain each synthetic resin composition. When the synthetic resin was a two-component curable resin, a main agent, a mineral, a binder component, an expansion agent, and an additive were mixed to serve as a first liquid, and a curing agent was served as a second liquid. A synthetic resin composition was a two-component type synthetic resin composition including the first and second liquids. The first and second liquids of the synthetic resin composition were mixed immediately prior to use, to cure the two-component curable resin. In an emulsion-based polymer, the mass of a solid content is shown.

[0198] The strength of a combustion residue of the synthetic resin composition after combustion in an atmosphere of 800° C. for 20 minutes was measured by the aforementioned procedure. The results are shown in Tables 1 to 6.

[0199] For the synthetic resin compositions of Examples 1 to 21, 25, and 27, and Comparative Examples 1 to 4, an I-type specimen in accordance with NPO JAPAN EXTERIOR FURNISING TECHNICAL CENTER standard JTC 5-0001 was aged at 23° C. and a relative humidity of 50% for 28 days. After that, the 50% modulus and the elongation ratio were measured by the aforementioned procedure. The results are shown in Tables 1, 2, 4 and 6.

[0200] For the synthetic resin compositions of Examples 1 to 26 and Comparative Examples 1 to 4, the joint-following property of each combustion residue after combustion in an atmosphere of 800° C. for 20 minutes was measured by the following procedure. The results are shown in Tables 1 to 4 and 6.

[0201] The shear strength of the synthetic resin compositions of Examples 22 to 24, 27 to 38, and Comparative Examples 5 to 10 was measured by the aforementioned procedure. The results are shown in Tables 3, 5, and 6.

[0202] For the synthetic resin compositions of Examples 22 to 24, 27 to 38, and Comparative Examples 5 to 10, the tile-holding property was measured by the following procedure. The results are shown in Tables 3, 5, and 6.

[0203] (Joint-following Property of Combustion Residue)

[0204] Two plates of external wall material (trade name “ALC” manufactured by Asahi Kasei Corporation) were prepared, and disposed so that the distance between facing surfaces of the two plates was 10 mm. A gap between the plates of the external wall material was formed as a sealing part. The sealing part was filled with the synthetic resin composition, and the synthetic resin composition was aged at 23° C. and a relative humidity of 50% for 28 days, to form a specimen. The specimen was burned in an atmosphere of 800° C. for 20 minutes. The length of the gap between the external wall material and a combustion residue of the synthetic resin composition was measured using a thickness gauge. The length of the gap was evaluated in accordance with the following criteria.

[0205] A (less than 0.5 mm)

[0206] B (0.5 mm or more and less than 1.0 mm)

[0207] C (1.0 mm or more)

[0208] (Tile-Holding Property)

[0209] Four tiles having a square planar shape with a side of 15 cm and a flat surface were prepared. The synthetic resin composition was melted, and then applied to a whole back surface of each of the tiles at a coating amount of 100 g/m.sup.2.

[0210] Subsequently, a mortar external wall material was prepared. On a surface of the external wall material, the four tiles were placed with the synthetic resin composition disposed on a side of the external wall material. The synthetic resin composition was then cooled and solidified or cured. Thus, the tiles were adhesively integrated with the surface of the external wall material, to produce a specimen. The distance between the adjacent tiles was 0.5 cm.

[0211] When the synthetic resin composition was cooled and solidified, the synthetic resin composition was left in an environment of 23° C. for 60. When the synthetic resin composition was cured, the synthetic resin composition was aged in an environment of 23° C. and a relative humidity of 50% for 1 month.

[0212] The specimen was left in a constant temperature bath of 600° C. for 30 minutes, burned, taken from the constant temperature bath, and then left in an atmosphere of 23° C. for 3 hours. The external wall material was made stand vertically, and the detachment or attachment of the four tiles was observed.

[0213] A (four tiles were not detached, and were very strongly bonded)

[0214] B (four tiles were not detached, but were very easily detached when they were touched by a hand)

[0215] C (one to three tiles were detached)

[0216] D (all four tiles were detached)

INDUSTRIAL APPLICABILITY

[0217] A combustion residue produced by combustion of the synthetic resin composition of the present invention is very rigid. The synthetic resin composition can be suitably used as a sealing material. The combustion residue can reliably hold a state where a joint part is filled therewith and clogged even during a fire, prevent flames from passing through a sealing part such as the joint part, and impart excellent fire-proof performance to a wall part of a building construction, and the like.

[0218] The synthetic resin composition can also be suitably used as an adhesive. For example, the combustion residue can rigidly hold a decorative article such as a tile adhesively integrated with a surface of the wall part even during a fire, and can effectively prevent the decorative article from detaching from the wall part.
