Abstract The self-healing effect of melamine-based surfaces, triggered by temperature, was investigated. The temperature triggered reversible healing chemistry, on which the self-healing effect is based, was the Diels-Alder (DA) reaction between furan and maleimide groups. Melamine-furan containing building blocks were connected by multi-functional maleimide crosslinker via a Diels-Alder (DA) reaction to give a DA adduct. The DA adduct was then reacted with formaldehyde to form a network by conventional condensation reaction of melamine amino groups with formaldehyde. The obtained resin was characterised and used for the impregnation of paper. Impregnated papers and neat resin were used to perform scratch-healing tests and mechanical analysis of the novel coating system.

Diels-Alder 改性自修复三聚氰胺树脂

摘要 研究了由温度引发的三聚氰胺基表面的自修复作用。温度触发的可逆愈合化学反应是自愈效应的基础，是呋喃和马来酰亚胺基团之间的狄尔斯-阿尔德 (DA) 反应。含有三聚氰胺-呋喃的结构单元通过多官能马来酰亚胺交联剂通过狄尔斯-阿尔德 (DA) 反应连接，得到 DA 加合物。然后DA加合物与甲醛反应以通过三聚氰胺氨基与甲醛的常规缩合反应形成网络。对所得树脂进行表征并用于纸的浸渍。浸渍纸和纯树脂用于对新型涂层系统进行划痕修复测试和机械分析。
