摘　　要：目前国内市场高粱田专用除草剂较少,为解决高粱田杂草问题,开展了高粱田专用除草剂39.8%氯吡酸·二氯喹·莠去津悬浮剂的配方研制。采用湿法研磨工艺,通过筛选润湿分散剂、增稠剂、防冻剂、增效剂、pH调节剂、高分子缓释剂等助剂种类及其用量,确定了39.8%氯吡酸·二氯喹·莠去津悬浮剂产品的优选配方:氯氟吡氧乙酸5.8%(折百)、二氯喹啉酸9%(折百)、莠去津25%(折百)、润湿分散剂烷基醇聚氧乙烯醚W-6001%、木质素磺酸钠MNS/901%、多聚芳基醚硫酸酯FD 3%、防冻剂乙二醇5%、pH调节剂柠檬酸0.2%、增效剂异构醇聚氧乙烯醚5%、药害减轻剂聚氨酯树脂5%、消泡剂6300.5%、防腐剂卡松0.2%、增稠剂黄原胶0.15%、硅酸镁铝1%,去离子水补足至100%。该制剂配方悬浮性优,贮存稳定性好,各项技术指标均符合悬浮剂的标准要求。At present,herbicides for sorghum field are few in the domestic market.In order to solve the problem of weeds in sorghum field,the formulation of fluroxypyr·quinclorac·atrazine 39.8%SC was developed.Wet grinding was adopted during the preparation of fluroxypyr·quinclorac·atrazine 39.8%SC with different wetting dispersing agents,thickening agents,antifreeze agents and other auxiliaries.The optimal formula of SC was fluroxypyr 5.8%(convert to a percentage),quinclorac 9%(convert to a percentage),atrazine 25%(convert to a percentage),wetting dispersant alkyl alcohol polyoxyethylene ether W-6001%,sodium lignosulfonate MNS/901%,polyaryl ether sulfate FD 3%,antifreeze glycol 5%,pH regulator citric acid 0.2%,synergist isomeric alcohol polyoxyethylene ether 5%,harm mitigating polyurethane resin5%,defoaming agent 6300.5%,preservative Casone 0.2%,thickening agent xanthan gum 0.15%,magnesium aluminum silicate 1%,and deionized water added up to 100%.The formulation has excellent suspension,good storage stability,and all technical indexes accord with the standard requirements of suspension agent.
