Abstract

In this paper, fully bio-based branched unsaturated polyester (BUPE) oligomers were synthesized by one-step solvent-free polycondensation using itaconic acid, isosorbide and glycerol as feedstocks. The branched structure was confirmed by Fourier-transform infrared spectroscopy (FTIR) and proton nuclear magnetic resonance spectroscopy (1H NMR). The effect of the branched structure on the properties of BUPE UV curing coatings was investigated. The results showed that the introduction of a glycerol branched structure was favorable for UV curing. The BUPE UV curing coatings based on the glycerol branched structure showed higher gel content and crosslink density, which enhanced the hardness, solvent resistance and mechanical properties of the coatings. In addition, the BUPE UV curing coatings possessed extremely low surface roughness, excellent heat resistance and light transmission properties.

全生物基支链不饱和聚酯低聚物的合成及UV固化涂料
以衣康酸、异山梨酯和甘油为原料,采用一步无溶剂缩聚法合成了全生物基支链不饱和聚酯(BUPE)低聚物。用傅里叶变换红外光谱(FTIR)和质子核磁共振谱(1H NMR)证实了支链结构。研究了支化结构对BUPE UV固化涂料性能的影响。结果表明,甘油支链结构的引入有利于紫外光固化。基于甘油支链结构的BUPE UV固化涂料具有较高的凝胶含量和交联密度,从而提高了涂层的硬度、耐溶剂性和力学性能。此外,BUPE UV固化涂料具有极低的表面粗糙度,优异的耐热性和透光性。
