Description

一种2,4-D盐水溶性粒剂及其制备方法
技术领域
本发明涉及一种农药除草剂及其制备方法，具体地说是涉及一种2,4-D盐的水溶性粒剂（即水溶性颗粒剂）及其制备方法。
背景技术
2,4-D为苯氧羧酸类选择性内吸传导激素性除草剂，纯品为白色晶体，在水中溶解度很小，易溶于乙醇、苯等有机溶剂，但其钠盐、胺盐则极易溶于水。具有较强的内吸传导性，在低浓度时能抑制植物生长发育，致出现畸形、直到死亡，主要用于苗后茎叶处理，对核酸和蛋白质的合成产生不同影响，使生长点停止生长，幼嫩叶片不能伸展，抑制光合作用的正常进行，传导到植株下部的药剂，促进细胞异常分裂，根尖膨大，丧失吸收能力，造成茎秆扭曲、畸形，筛管堵塞，韧皮部破坏，有机物运输受阻，导致植物死亡。2,4-D类除草剂对大豆田和其他豆科植物田的一年或多年生禾本科杂草和某些阔叶杂草有优异的防效，如苋菜、蓼、藜、龙葵、苍耳、稗草、狗尾草、马唐、黍等杂草。
2,4-D主要剂型为其酯类的乳油和其盐的水剂。由于乳油中的有机溶剂易燃且会造成环境污染较大，近年来该剂型在农药制剂中的比重逐年下降。而2,4-D盐水剂虽然属于环境友好型剂型，但是高浓度的水剂在低温时极易出现结晶，低浓度水剂虽然会出现结晶，但却增加了包装和运输成本，在一定程度上也限制了其使用。
发明内容
为了克服现有技术中的不足，本发明提供一种2,4-D盐水溶性粒剂，该水溶性粒剂成分简单，对环境友好，与现有其他剂型相比更便于应用。
本发明还提供该水溶性粒剂的制备方法，通过本制备工艺可以方便的将2,4-D盐制成水溶性粒剂，成粒简单，便于操作。
本发明是通过以下技术方案实现：
一种2,4-D盐水溶性粒剂，包括以下重量百分数的成分：2,4-D盐5-80%(以2,4-D酸计)，水溶性填料补至100%。
上述2,4-D盐水溶性粒剂中，所述的2,4-D盐选自异丙胺盐、乙胺盐、一甲胺盐、二甲胺盐、钠盐、钾盐和铵盐中的一种或多种。
上述2,4-D盐水溶性粒剂中，不需要加入任何表面活性剂和粘结剂，仅需水溶性填料即可制得水溶性颗粒，所用的水溶性填料为水溶性无机盐，所述水溶性无机盐选自硫酸盐、硝酸盐、盐酸盐、碳酸盐、碳酸氢盐、磷酸盐、磷酸氢二盐、磷酸二氢盐、硼酸盐和硅酸盐中一种或多种。
上述2,4-D盐水溶性粒剂中，所用的水溶性无机盐可以按照任意比例混合。
本发明将2,4-D盐类药物制成水分散粒剂，克服了水剂存在的不足，在应用上更加便利。本发明的水分散粒剂不需要加入表面活性剂、粘合剂等辅料成分，成分更加简单，但是2,4-D盐不加粘合剂、表面活性剂成分很难造粒，本发明针对水溶性粒剂的组成，研究得到了适合于其的制备方法，使造粒方便易行，便于操作。
本发明制备方法为：将2,4-D盐和水溶性填料在捏合机中充分均匀混合后，然后加入2,4-D盐和水溶性填料总量1-10wt%的水进行捏合，捏合完毕后在40-110℃造粒， 20-90℃条件下烘干即得。
上述制备方法中，造粒时不需用加入任何粘结剂和表面活性剂，只需保证混合料在40-110℃进行造粒即可。
与现有技术相比，本发明的2,4-D盐水溶性粒剂具有如下优点：
1.生产工艺简易、经济、安全。整个生产过程不使用危化品，易于控制和操作，安全系数高。
2.水溶性粒剂属于环境友好型剂型，与常规乳油、可湿性粉剂、悬浮剂相比具有无有机溶剂、无粉尘、易计量的优点。
3. 所得2,4-D盐水溶性粒剂使用方便，降低了包装和储运成本，适宜于大面积推广使用。
