摘要

基于聚酯酰胺(PEA)的聚合物系统是高性能材料,它结合了聚酯和聚酰胺树脂的有用特性。本文制备了一种新型改性聚酯酰胺树脂,并对其作为表面涂层的粘结剂进行了评价。以邻苯二酸酐为原料,以N,N-双-(2-羟乙基)大豆油脂肪酸酰胺(HESFAA)为多元醇源和微生物防腐剂,合成了该树脂。测定树脂的酸值为7 mg KOH/g,表明树脂已完全形成。通过红外光谱研究证实了树脂的结构。结果表明,改性提高了PEA的物理力学性能和化学性能。从分析结果来看,合成的树脂可以作为不同类型涂料的粘结剂。关键词:粘结剂,邻苯二酸酐,聚酯酰胺,大豆油脂肪酸

Preparation and characterization of polyester amide resin derived from Nigerian soya bean oil and its performance evaluation as binder for surface coatings
Polymeric systems based on polyesteramides (PEA) are high performance materials, which combine the useful properties of polyester and polyamide resins. In this work, a new modified polyesteramide resin was prepared and evaluated as binder for surface coating.The resin was synthesised by the reaction of N,N-bis-(2-hydroxyethyl) soya bean oil fatty acid amide (HESFAA) as a source of the polyol and as preservative against microbiological attack, with phthalic anhydride as the ingredient source of the polybasic acid. The measured acid value of the resin was found to be 7 mg KOH/g, which indicates the complete formation of the resin. The structure of the resin was confirmed by FT-IR spectral studies. The results show that the modification enhances both phyisco-mechanical and chemical properties of the PEA. From the analyses carried out, the synthesized resin could be suitable as binder for different types of paint. Keywords: Binder, Phthalic anhydride, Polyester amide, Soya bean oil fatty acid
