一种农药水分散泡腾片剂及其制备方法

Pesticide water effervescent dispersible tablet and preparation method thereof

Abstract

本发明公开了一种农药水分散泡腾片剂及其制备方法,以碳酸氢铵为发气源,根据不同原药的物性可选择酸源或碱源,相对耐酸的原药加入酸源和碳酸氢铵,使用时片剂入水产生二氧化碳;相对耐碱的原药加入碱源和碳酸氢铵,使用时片剂入水产生氨气。本发明农药水分散泡腾片剂在水中能迅速沸腾崩解,能避免农药水分散泡腾片剂有效成分降解,使用效果下降,从而获得化学性能稳定的农药水分散泡腾片剂。
The invention discloses a pesticide water effervescent dispersible tablet and a preparation method thereof. According to the pesticide water effervescent dispersible tablet and the preparation method thereof, ammonium hydrogen carbonate is used as a gas source, and an acid source or alkali source is selected according to the physical property of different raw materials, i.e. the acid source and the ammonium hydrogen carbonate are added into the acid-resistant raw materials, and tablets are put into water to produce carbon oxide during use; and the alkali source and the ammonium hydrogen carbonate are added into the alkali-resistant raw materials, and tablets are put into water to produce ammonia gas. The pesticide water effervescent dispersible tablet can rapidly boil and disintegrate in water and therefore avoid the reduction of application effect caused by degradation of effective components of the pesticide effervescent dispersible tablet, so that the pesticide water effervescent dispersible tablet with stable chemical properties is obtained.
