In this study, the synthesis, characterization, and properties of a short oil length chain-stopped(rapid) alkyd resin is investigated. Gum rosin modified alkyd resin (RA-GR) was prepared using soybean oil, phthalic anhydride, glycerin and gum rosin acid. An alkyd modified with benzoic acid (RA-BA) was also prepared for comparison. FTIR analyses and GPC measurements of the alkyds were used for characterization. Other properties such as the viscosity, acid value, and solid content of the final resins were determined. Separately, the synthesized resins were used in paint formulations without any changes in other parameters such as filler, airdrying agents, solvents, etc. Paints were applied to metal and glass surfaces and the effect of gum rosin was investigated by looking at touch and hard drying times, adhesion to metals and gloss changes. Compared to the benzoic acid modified resin (RA-BA), gum rosin modified resin (RA-GR) exhibited remarkable positive effects on the paint with a better adhesion to the metals, and short drying times without any loses in the glosses.
在本研究中，对一种短油长链终止（快速）醇酸树脂的合成、表征及性能进行了研究。使用大豆油、邻苯二甲酸酐、甘油和松香酸制备了松香改性醇酸树脂（RA-GR）。还制备了用苯甲酸改性的醇酸树脂（RA-BA）用于比较。通过傅里叶变换红外光谱（FTIR）分析和凝胶渗透色谱（GPC）测量对醇酸树脂进行表征。测定了最终树脂的其他性能，如粘度、酸值和固含量。另外，合成树脂在涂料配方中使用时，在填料、风干剂、溶剂等其他参数方面未作任何改变。将涂料涂覆在金属和玻璃表面，通过观察触干和硬干时间、对金属的附着力以及光泽变化来研究松香的作用。与苯甲酸改性树脂（RA-BA）相比，松香改性树脂（RA-GR）对涂料表现出显著的积极影响，对金属具有更好的附着力，干燥时间短，且光泽无任何损失。
