摘要：

为研究表面活性剂复配制备水基型氯氰菊酯微乳剂的稳定性及润湿展布性。采用紫外-可见分光光度法和气相色谱法测定水基型氯氰菊酯微乳剂的稳定性，用视频光学接触角测量仪测定其表面张力和在杨福麦7116叶面上的接触角。结果表明，该农药微乳剂具有较好的化学稳定性和经时稳定性；表面张力较低，且与杨福麦7116叶面接触角小，铺展速度快，在植物叶面易附着、易润湿、易铺展，宜用于农用喷洒。

Abstract:

In order to study the stability and wet-spreading of water-based cypermethrin microemulsions prepared by the mixed surfactants. The stability of water-based cypermethrin microemulsions prepared was studied by the methods of uv-vis spectroscopy and gas chromatograph. The contact angles on Yangfu wheat leaf were measured by using the optical contact angle measuring device. The results showed that the water-based cypermethrin microemulsions have good properties of chemical stability and ageing stability, and have lower surface tension. The contact angles were lower when the solutions were dropped on Yangfu wheat leaf. The results proved that the water-based cypermethrin microemulsions were easily attached to the plant surface, wetting and spreading fastly, so they are suitable to agricultural.
