The invention discloses an alkyd resin used for nitrolacquers, and relates to the technical field of resin processing. A preparation method of the alkyd resin comprises the following steps: 1, esterification polycondensation; 2, diluting, stirring, and cooling; and 3, filtration. The alkyd resin is a nitrolacquer auxiliary film forming substance, and cooperates with nitrocellulose to prepare nitrolacquers in order to fully improve the brushability and the adhesion of paints and shorten the drying time, and paint films formed after the paints formed by the alkyd resin solidify have excellent light and color maintenance property, wear resistance, water resistance, corrosion resistance, weatherability and insulating property, so the application range of the nitrolacquers is widened, and the service life of the paint films is prolonged. 本发明公开了种硝基漆用醇酸树脂，涉及树脂加工技术领域，其制备方法包括如下步骤：(1)酯化缩聚，(2)兑稀、搅拌、冷却，(3)过滤。本发明醇酸树脂是硝基漆的辅助成膜物质，与硝化棉协同制得硝基漆，以充分提高漆料的涂刷性和附着力，缩短干燥时间，并且固化形成的漆膜具有优异的保光保色性、耐磨性、耐水性、耐腐蚀性、耐候性和绝缘性，从而扩大气硝基漆的使用范围和延长漆膜的
