摘要

粘合剂广泛用于工业和建筑业，无甲醛的选择由于其增强的安全性和化学稳定性而越来越受欢迎。然而，它们的耐水性仍然有很大的限制。本研究提出了一种基于物理化学双交联协同网络的简单高效的策略来开发新型无甲醛胶粘剂（IBMP-BT）。独特的结构，具有稳定的化学交联形成的酰胺和多个氢键的网络，使增强的耐水性，强度和韧性的粘合剂。IBMP-BT胶粘剂的干抗剪强度和韧性分别达到2.03 MPa和0.600 J，比未改性胶粘剂分别提高了89.7%和255.03%。IBMP-BT胶粘剂湿粘强度为1.16 MPa，明显超过中国国家标准要求。这种创新的网络设计使烯烃共聚物能够取代传统的甲醛基产品，从而创造出高性能的粘合剂。

Advanced Dual-Cross-Linking Strategy for Upgrading Formaldehyde-Free Olefin Adhesives

Adhesives are extensively used in industry and construction, with formaldehyde-free options gaining popularity due to their enhanced safety and chemical stability. However, their water resistance remains a significant limitation. In this study, a simple and efficient strategy based on a physicochemical dual cross-linking synergistic network was proposed to develop a new formaldehyde-free adhesive (IBMP-BT). The unique structure, featuring stable chemical cross-linking formed by amidation and a network of multiple hydrogen bonds, enables enhanced water resistance, strength, and toughness of the adhesive. The dry shear strength and toughness of the IBMP-BT adhesive reached 2.03 MPa and 0.600 J, respectively, representing improvements of 89.7% and 255.03% compared to those of the unmodified adhesive. The wet bonding strength of the IBMP-BT adhesive was 1.16 MPa, significantly exceeding the requirements of China’s national standards. This innovative network design allows olefin copolymers to replace traditional formaldehyde-based products, leading to the creation of high-performance adhesives.
