The study describes the curing and thermal behavior of a new castor oil maleic anhydride adduct/epoxy oils/5-Bromosalicylic acid coatings and their composites with wood. The epoxidized oils were flax and hemp. The kinetic parameters of the curing and thermal degradation processes were calculated. The resistance of the coated wood surfaces against , , and was tested. Color changes, FT-IR and SEM were conducted before and after fungal attack. The decay resistance and color change of raw wood and wood treated samples against fungi was tested. Based on the color changes and according to ASTM D 2017, the decay resistance rating for covered samples was considered as "highly resistant". Chemical resistance and coating performance tests were also undertaken. The obtained results recommend the described materials for applications in wood protective coatings.
本研究描述了一种新型蓖麻油马来酸酐加合物/环氧油/5- 溴水杨酸涂料及其与木材的复合材料的固化和热行为。所使用的环氧油为亚麻油和大麻油。计算了固化和热降解过程的动力学参数。测试了涂覆木材表面对 、 、 和 的抗性。在真菌攻击前后进行了颜色变化、FT-IR 和 SEM 分析。测试了未经处理和经处理的木材样品对真菌的耐腐性和颜色变化。根据颜色变化，并根据 ASTM D 2017，覆盖样品的耐腐性评级被认为是“高度耐腐”。还进行了化学抗性和涂层性能测试。获得的结果表明，所描述的材料可用于木材保护涂料。
