問題があった。Structure of conventional examples and their problems Conventionally, rubber-based, vinyl acetate-based, epoxy-based, urethane-based adhesives, etc., used for industrial and general purposes, have a tendency to evaporate their solvents or cause the two liquids to evaporate. As a result of the reaction, only the solid content remains and the adhesive solidifies, but adhesives that evaporate the solvent cause thinning, making it impossible to use them for purposes that combine adhesion and sealing. In addition, two-component reaction type adhesives and one-component thermosetting adhesives also tend to sag in areas with large gaps, making it impossible to use them for both gap sealing and adhesion. Therefore, in areas where sealing and adhesion are required, it is necessary to seal the gap with foamed resin such as foamed polyethylene, and then pour adhesive over it to perform bonding, which poses the problem of increasing the number of work steps.
発明の目的
本発明は、上記従来例の欠点を除去するものであり、接
着剤に発泡性を付与し、スキ間のシールと接着を同時に
行えるようにしたものである。OBJECTS OF THE INVENTION The present invention eliminates the drawbacks of the above-mentioned conventional examples, and provides a foaming property to the adhesive so that sealing between gaps and adhesion can be performed at the same time.
発明の構成
本発明は、上記目的を達成するために、接着剤に加熱す

し、接着の使用範囲を大幅に拡大するものである。Structure of the Invention In order to achieve the above object, the present invention mixes a synthetic resin containing a gas that foams when heated into an adhesive, and heats the adhesive after bonding to create a seal between the gaps. Since it has both adhesive properties and heat insulation properties due to the use of synthetic resin, it can be used to bond areas where heat conduction is not desired, greatly expanding the range of adhesive applications.
実施例の説明 以下本発明の一実施例の構成について説明する。Description of examples The configuration of one embodiment of the present invention will be described below.
本発明は、２液反応タイプのウレタン系接着剤の硬化剤

接着剤が硬化するとともに接着剤が発泡する。上記合成
樹脂微粉末の混入量を変えることにより発泡倍率も任意
に変えることができる。In the present invention, the diameter of the synthetic resin containing a gas such as butane gas in the curing agent of a two-component reaction type urethane adhesive is 5 μm.
By mixing a fine powder of ~30 microns and using the reaction heat generated when the main resin and curing agent are mixed and reacted, the fine powder synthetic resin is expanded by about 4 times in diameter. The adhesive foams as it hardens. By changing the amount of the synthetic resin fine powder mixed in, the expansion ratio can also be changed arbitrarily.
また別の実施例として、上記合成樹脂の微粉末が接着材
により溶剤されるものを使用し接着剤に混入と同時に接
着、発泡させてもよいものである。In another embodiment, the fine powder of the synthetic resin may be used as a solvent by an adhesive, and may be mixed into the adhesive and simultaneously bonded and foamed.

きる等の効果を有する。Effects of the Invention In the present invention, since the adhesive contains a synthetic resin or a foaming agent that foams when heated, the adhesive foams to form both a seal between gaps and adhesion, and also improves heat insulation properties. Because of this, it can also be used for adhesion in areas that require heat insulation.Furthermore, the expansion ratio can be changed arbitrarily, and by increasing the expansion ratio, it has the effect of reducing the amount of adhesive used.
