ミド系に限定されるが、高価格、作業性、高温下の使用
における接着強度等の問題があった。As a recent tendency for polymer adhesives, pollution resistance and heat resistance are being demanded. Therefore, a so-called hot melt adhesive that does not require the use of a solvent has been attracting attention as a pollution-free adhesive. However, conventional hot melt adhesives have a problem in heat resistance, and only a small part of thermosetting, such as polyimide, can be used in an environment of 100 ° C or higher, but high price, workability, and high temperature. There was a problem such as adhesive strength in the use below.
一方、近年の接着技術の進歩に伴い、金属板等の金属材

使用した場合に金属板が剥離する、いわゆる界面破壊が
生じる懸念があるという問題もあった。On the other hand, with the recent progress of the bonding technique, it has become more common to bond metal materials such as metal plates with an adhesive.
In particular, there is a demand for an adhesive that can firmly bond a joint to which an external force is applied such as a structural joint, and expectations for a high-strength adhesive having high heat resistance are increasing. In conventional polymer adhesives, the expansion coefficient of the base polymer is very different from that of metal, so even if initially adhered firmly, the metal plate peels off when used at high temperatures, so-called interface fracture There was also a problem that there is a concern that there may occur.
