Abstract

The invention discloses a 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet and a preparation method thereof. The 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet consists of the following materials in percentage by weight: 0.1 to 80 percent of 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt, 0.5 to 15 percent of dispersing agent, 0.5 to 8 percent of wetting agent, 0.1 to 35 percent of disintegrating agent, 0 to 10 percent of binder and the balance filler. The preparation method of the 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet includes the following steps: all the materials of the 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet are mixed, ultra-finely milled by jet, pelletized, dried, granulated or tableted, chosen and inspected, and thereby the 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet is obtained. The 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet is safe for the environment, the human being, livestock and other beneficial organisms, cannot easily produce chemical hazards, can be accurately weighed, and is convenient to use; the 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet can be rapidly disintegrated; the storage stability of the 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet is high, the preparation process is simple, and the 2-methyl-4-chlorophenoxy acetic acid and 2-methyl-4-chlorophenoxy acetic acid salt water-dispersible granule or tablet is suitable for industrialized production and wide popularization and application.
本发明公开了一种二甲四氯及二甲四氯盐水分散粒剂/或片剂及其制备方法。该二甲四氯及二甲四氯盐水分散粒剂/或片剂,由下述质量百分比的原料组成:二甲四氯及二甲四氯盐0.1%~80%、分散剂0.5%~15%、润湿剂0.5%~8%、崩解剂0.1~35%、粘结剂0%-10%、余量为填料。其制备方法是将组成二甲四氯及二甲四氯盐水分散粒剂/或片剂的各原料混合,经超微/气流粉碎后造粒,烘干,整粒/压片,精选,检测,即得。本发明的二甲四氯及二甲四氯盐水分散粒剂/或片剂对环境、人畜及其它有益生物安全,不易产生药害,计量准确,使用方便;崩解速度快;贮藏稳定性良好,制备工艺简单,适宜工业化生产和农业大面积推广应用。
