反应型丙烯酸酯胶黏剂的性能特点及应用范围有哪些?

从甲基丙烯酸酯的自由基聚合的机理可发现,室温快速固化丙烯酸酯胶黏剂的特征和优点如下:

① 采用氧化还原引发体系,聚合活化能低。室温下可快速固化,且配比不严格。

② 单体组合的多样性,使得聚合物性能具有多样性,可广泛粘接各种材料。

③ 单体对油脂、水等的可溶性,对金属表面的高度浸润性,油面可粘接性。

④ 自由基接枝共聚和相分离技术。树脂综合性能提高,特别是耐冲击、耐剥离、耐老化性能有质的飞越。

基于以上优越的使用性能,反应型丙烯酸酯胶黏剂可用于粘接不锈钢、铝合金、钢、铜、铁等金属材料,也可粘接硬塑料、硬橡胶、陶瓷、玻璃等非金属材料,已用于扬声器磁回路、衡器、刀具、量具、装饰嵌件、工艺品、电子零件等各方面的粘接。还可用于汽车油箱、机械裂缝的修复,铸件砂眼的填补,文物古董的修复,以及其他野外应急抢修等。

From the mechanism of free radical polymerization of methacrylate, it can be found that the characteristics and advantages of room temperature fast curing acrylate adhesive are as follows:

① Using redox initiation system, the activation energy of polymerization is low. It can be cured rapidly at room temperature, and the ratio is not strict.

② Due to the diversity of monomer combination, the polymer has a variety of properties and can be widely bonded to various materials.

③ The solubility of monomer to oil, water, etc., the high wettability to metal surface, and the adhesiveness of oil surface.

④ Free radical graft copolymerization and phase separation technology. The comprehensive properties of the resin were improved, especially the impact resistance, peeling resistance and aging resistance.

Based on the above excellent performance, reactive acrylate adhesive can be used to bond stainless steel, aluminum alloy, steel, copper, iron and other metal materials, and also can bond hard plastic, hard rubber, ceramics, glass and other non-metal materials. It has been used in the bonding of loudspeaker magnetic circuit, weighing apparatus, cutting tools, measuring tools, decorative inserts, handicrafts, electronic parts and other aspects. It can also be used for repairing automobile fuel tank and mechanical crack, filling casting sand hole, repairing cultural relics and antiques, and other field emergency repair.
