采用湿式超微粉碎法对20%丁硫克百威.戊唑醇悬浮种衣剂进行了研究,对润湿分散剂、成膜剂、增稠剂、防冻剂进行了筛选,确定了优惠配方:丁硫克百威19.0%,戊唑醇1.0%,壬基酚聚氧乙烯醚3.0%,苯乙烯苯酚甲醛树脂聚氧乙烯醚磷酸酯盐1.5%,黄原胶0.1%,成膜剂2.0%,尿素3.0%,玫瑰精0.5%,正辛醇0.5%,水补足。结果表明:该产品悬浮率90%以上,热贮([54±2)℃1,4 d]分解率小于5%,种子包衣质量比为1:150,包衣均匀等特点,产品各项指标符合悬浮剂种衣剂的要求。
The wet ultrafine pulverization method was used to study the suspension coating agent of 20% carbothiazide and tebuconazole, and the wetting and dispersing agent, film-forming agent, thickener and antifreeze were screened to determine the preferential formula : 19.0% of metsulfuron-methyl, 1.0% of tebuconazole, 3.0% of nonylphenol polyoxyethylene ether, 1.5% of polyoxyethylene ether phosphate ester of styrene-phenol formaldehyde resin, 0.1% of xanthan gum, film-forming agent 2.0 %, Urea 3.0%, rose essence 0.5%, n-octanol 0.5%, water make up. The results showed that the product had more than 90% suspension, less than 5% thermal storage ([54 ± 2] ℃ and 1,4 d] decomposition rate, 1: 150 seed coating weight, Index in line with the requirements of the suspension coating agent.
