Abstract
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.
Description
Technical field
The present invention relates to a kind of pesticide processing field, relate in particular to soaked dispersion effervescent tablet of a kind of agricultural chemicals and preparation method thereof.
Background technology
Effervescent tablet is a kind of pesticides new formulation of fast development, this tablet is met water can produce rapidly a large amount of bubbles, and in water, foaming boiling, disintegration fast, be dispersed in water active ingredient uniformly, formation has solution or the aqueous dispersion of good action effect, and suspensibility and dispersiveness are higher.
It is in tablet, to contain acidic materials (acid source that pesticide water disperses the general principle of effervescent tablet, be generally citric acid, tartaric acid, fumaric acid etc.) and the material of the getting angry (source of getting angry, be generally the basic salt containing carbonate, as carbonic hydroammonium, sodium carbonate etc.), there is neutralization reaction with the source of getting angry in acid source after tablet is met water, discharge carbonic acid gas, thereby reach foaming boiling, quickly disintegrated effect, pesticide water disperses effervescent tablet can directly shed in use disintegration diffusion voluntarily in paddy field, also can drop into disintegration in sprayer and spray in crop target after disperseing.
The pesticidal preparations of China is mainly missible oil and pulvis at present, because missible oil uses a large amount of chemical solvent-as toluene, dimethylbenzene etc. cause very big injury to environment and user, pulvis flies upward drift because it is serious, particularly serious to user's injury, metering difficulty when these two kinds of formulations also exist packaging to use, and aqueous dispersion effervescent tablet is owing to having given configuration, accurately monolithic weight, solvent-free, without drift, easy to use, there is again foaming boiling simultaneously, disintegration fast, higher suspension rate and dispersive property, it is a kind of environmentally friendly pesticides new formulation, become the frontier that current pesticidal preparations develops rapidly.
Pesticide water disperses effervescent tablet to be generally made up of pesticide original medicine, acid source, carbon dioxide source, surfactant, free-flow agent, binding agent, inert filler etc., described in the patent No. 00107465.2,200610104832.3, but most Pesticidal products are not to be exactly unstable to alkali to acid, very easily decompose, thereby cause product poor chemical stability, active ingredient degraded, result of use declines.
