| 摘 要： | 研究了松香改性对生漆漆膜性能的影响.研究结果表明,加入松香或乙醇溶解的松香均能改善生漆漆膜性能,加入生漆质量5%的松香效果最佳.生漆与金属铁离子反应后,再用5%松香改性,漆膜性能显著提高,干燥时间缩短为53h,附着力为4 ～ 5级,耐冲击力为30kg/cm,硬度为2H.红外光谱分析表明,生漆中的漆酚和松香中的树脂酸发生酯化反应,从而改善了漆膜特性.

| Abstract: | Effect of adding rosin into raw lacquer on the film properties was studied. The result showed that the addition of rosin or its alcoholic solution can improved the film properties. The film properties are the best when rosin dosage is 5%. The film properties were improved significantly when 5% rosin was added into the reation product of raw lacquer and Fe~(3 +) , the drying time is shortened to 53h, film adhesion is 4 - 5 level, impact resistance is less than 30kg/cm, film hardness ( by pencil test ) is 2H. The result of IR showed that ester was obtained from the esterification of hydroxyl of the raw lacquer with the carboxyl of the rosin, which improves the film properties. |
