However, if a larger amount of filler is contained in the adhesive composition, it is possible to prevent the displacement of a relatively heavy structural material such as a tile at the time of adhesion.

There was a problem. Not only that, when the content of the filler is increased, the flexibility after curing is reduced. That is, there is a problem that the advantage of blending the modified silicon compound, that is, imparting flexibility to the cured product, is lost.

As is clear from Table 1, in the adhesives having the compounding ratios of Examples 1 to 5, the two-liquid mixing property is good, the flexibility after curing is also excellent, and the tile is displaced. You can see that not. On the other hand, Comparative Examples 1 to 13
It is understood that the adhesive composition having the compounding ratio of 2 cannot satisfy any one of the two-component mixing property, the curing flexibility and the deviation of the tile.

〔発明の効果〕〔The invention's effect〕

以上のように、本発明によれば、適度な揺変性を有し、
硬化後の柔軟性の点においても優れているだけでなく、
タイル等の構造材を垂直方向に延びる面に接着した場合
に、構造材のずれが生じ難い接着剤を得ることができ
る。
As described above, according to the present invention, it has appropriate thixotropy,
Not only is it excellent in flexibility after curing,
When a structural material such as a tile is bonded to a surface that extends in the vertical direction, an adhesive agent that is less likely to cause displacement of the structural material can be obtained.

Moreover, when configured as a two-component adhesive, it becomes possible to provide an adhesive for on-site construction which is excellent in workability and which can be smoothly mixed and applied. Particularly, in the system to which the adhesive composition of the present invention belongs, agent A: agent B is generally used in a weight ratio of 2: 1.
However, in the adhesive composition of the present invention, agent A and agent B are mixed in a volume ratio of 1: 1 as in Examples 2 and 3.
It becomes possible to design the composition so that Therefore,
If the composition is designed such that the agent A and the agent B are mixed in a volume ratio of 1: 1 and used, it is possible to easily mix and bond them on site without using a measuring instrument.
