以高分子聚合树脂为成膜材料，与乳化剂、增塑剂、色素等助剂配制，制得控释包衣剂用于尿素包衣，以期将普通尿素转变为控释尿素。运用单因素试验和正交试验 L9（34）确定各组分最佳用量，并对其理化性质进行测定。研究结果表明，尿素控释包衣剂最佳制备条件为成膜材料树脂用量8％（质量分数，下同）、乳化剂T-80用量1．5％、增塑剂植物油用量2．0％、色素分散艳红用量0．16％、烘烤时间25 min，在此条件下制得的尿素控释包衣剂理化性质良好，适于尿素包衣。

Using high polymer resin as coating material,and emulsifier,plasticizer and pigment as additives,the controlled release coating agent for coated urea is prepared,which can turn common urea to controlled-release urea.The single factor test and orthogonal test L9 (34 ) are used to determine the optimum volumes of each component, and their physicochemical properties are determined.Study results show that the optimum preparation condition of coating agent for controlled-release urea is the volume of coating material resin is 8% (mass fraction,similarly hereinafter), emulsifier T-80 is 1.5%,plasticizer vegetable oil is 2.0%,pigment disperse brilliant red is 0.16%, the baking time is 25 min,the physicochemical properties of coating agent for controlled-release urea made under this condition are good,and is suitable for coated of urea.
