摘要:

无溶剂黏合剂因其绿色环保、操作简便以及适用范围广等优点,已成为食品与医药包装、电子器件、汽车制造及航空航天等领域中不可或缺的关键辅助材料。 本文筛选廉价的苯丙氨酸为构筑基元,通过简单的热辅助工艺,成功制备了一系列无溶剂黏合剂。 所制备的无溶剂黏合剂能黏接多种天然和人造基材,黏附强度最高可达1.84 MPa; 具有良好的持久黏附性(>15 d)、循环黏接性(>10次)和耐非极性溶剂性; 使用温度宽广(-196~80 ℃),可注入到不同形状的微管和用于工艺品的修复,能黏附生物组织并呈现出良好的生物相容性。 值得注意的是,无溶剂黏合剂可通过简单的热辅助工艺轻松实现千克级制备。 本文中开发的无溶剂黏合剂为推动绿色制造和可持续发展的黏性材料提供了可靠依据与指导。

Abstract:

Solvent-free adhesives are indispensable auxiliary materials in the fields of food and pharmaceutical packaging, electronic devices, automotive manufacturing and aerospace due to their advantages of eco-friendliness, ease of use, and wide applicability. Herein, we have screened inexpensive phenylalanine as building blocks and successfully prepared a series of new solvent-free adhesives through a simple heat-assisted process. This solvent-free adhesive can be bonded to a variety of natural and artificial substrates, the adhesion strength can reach up to 1.84 MPa; Excellent durable adhesion (>15 days), cyclic adhesion (>10 cycles) and non-polar solvent tolerance; A wide operating temperature (-196~80 ℃), can be injected into different shapes of microtubes and crafts for repair, and adhere to biological tissues and exhibit good biocompatibility. Notably, this solvent-free adhesive can be easily achieved for kilogram-scale preparation by a simple heat-assisted process. The work in this paper provides a reliable basis and guidance for promoting green manufacturing and sustainable development of adhesive materials.
