摘要:
氟乐灵是一种广泛适用于一年生禾本科杂草的芽前除草剂,为改善氟乐灵在使用过程中易光解、易挥发引起的利用率低、持效期短等问题,通过界面聚合法以氟乐灵为原药,制备了30%氟乐灵微囊悬浮剂,研究了乳化剂、芯材溶剂、保护胶体和其他助剂在微囊制备中的影响,并通过添加表面活性剂来改善微囊悬浮剂界面性能以调控微囊释放速率。结果表明,以150#芳烃溶剂油为芯材溶剂、SP-27001为乳化剂、质量分数3% XG为保护胶体、SP-2206为分散剂,最后加入硅酸镁铝、丙三醇、黄原胶、凯松,可得到达标的氟乐灵微囊悬浮剂。性能表征结果表明,所得悬浮剂性能指标达标,微囊形貌良好且分布均匀,D90为6.260 μm,有效含量30.7%,悬浮率98%,物理稳定性良好,加入助剂SP-4028的微囊释放速率可达乳油剂释放水平,对早熟禾防效显著,与乳油剂基本处于同一水平。
