Abstract
本发明的一种微波热熔型环氧树脂胶粘剂及其应用，该微波热熔型环氧树脂胶粘剂各组分按照重量比包括：环氧树脂100份、固化剂50～100份、添加剂10～60份、微波吸收剂10～30份。采用本发明的微波热熔型环氧树脂胶粘剂，具体可涂抹于夹片式锚具的锚环内壁中形成包裹层。也可代替现有的缓粘结剂，应用于缓粘结预应力钢绞线中。当需要将上述结构拆除时，在应用了本发明的微波热熔型环氧树脂胶粘剂的锚固端区域，施加微波场，胶粘剂内部的微波吸收剂将微波能转为热能，使得温度升高。当温度达到一定数值后，环氧树脂胶粘剂自行熔化，实现锚具与锚索夹片、锚具与预应力钢绞线间相脱离，进而完成拆除工作。A microwave hot-melt epoxy resin adhesive and application thereof of the present invention are disclosed. The components of the microwave hot-melt epoxy resin adhesive include, according to the weight ratio, 100 parts of epoxy resin, 50-100 parts of curing agent, and 10-100 parts of additives. 60 parts, microwave absorbent 10-30 parts. The microwave hot-melt epoxy resin adhesive of the present invention can be smeared on the inner wall of the anchor ring of the clip-type anchor to form a wrapping layer. It can also replace the existing slow-bonding agent and be used in slow-bonding prestressed steel strands. When the above structure needs to be dismantled, a microwave field is applied to the anchor end region where the microwave hot-melt epoxy resin adhesive of the present invention is applied, and the microwave absorbent inside the adhesive converts microwave energy into heat energy to increase the temperature. When the temperature reaches a certain value, the epoxy resin adhesive melts by itself, realizing the separation between the anchor and the anchor cable clip, the anchor and the prestressed steel strand, and then the dismantling work is completed.
