摘　　要：通过液体动/静态表面张力、铺展面积、接触角、药害等测试,研究了不同表面助剂对三硅氧烷表面活性剂(SE-90)进行二元及三元复配前后性能。结果显示:多种非离子表面活性剂能降低三硅氧烷表面活性剂的动态表面张力,其中具有较高HLB值的窄分布异构十三醇聚氧乙烯醚(9EO,S90)能显著提高三硅氧烷表面活性剂在动态中快速平衡水溶液表面张力的能力,且当wSE-90:wS90=7:1时效果最佳;糖基表面活性剂SWE-30可显著降低三硅氧烷表面活性剂的药害,当wSE-90:wS90:wSWE-30=7:1:2且总施药添加量为0.1%~0.033 %之间时,对5.7 %百树菊酯乳油的增效效果最理想。The effects of different surface additives on the properties of trisiloxane surfactant(SE-90) before and after binary and ternary compound were studied by testing the dynamic/static surface tension,spreading area,contact angle and phytotoxicity.The results show that a variety of nonionic surfactants can reduce the dynamic surface tension of trisiloxane surfactants,and the iso-tridecanol polyoxyethylene ether(9EO,S90) with high HLB value and narrow molecular weight distribution can significantly improve the ability of trisiloxane surfactants to rapidly balance the surface tension of aqueous solution,and the best effect is when wse-90::wS90=7:1.Glycosyl-based surfactant SWE-30 can significantly reduce the phytotoxicity of trisiloxane surfactant.When the ratio of wSE-90:wS90:wSWE-30 was 7:1:2 and the total dosage was between 0.1 % and 0.033 %,the synergistic effect of 5.7 % beta-cyfluthrin emulsifiable concentrate was the best.
