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 a large amount of bubbles rapidly, and foaming boiling, disintegration fast are dispersed in active ingredient in the water uniformly in water; Formation has the solution or the aqueous dispersion of good action effect, and suspensibility is with dispersed higher.
The basic principle of agricultural chemicals aqueous dispersion effervescent tablet is in tablet, to contain acidic materials (acid source; 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 of carbon containing acid group, like carbonic hydroammonium, sodium carbonate etc.), neutralization reaction takes place 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, agricultural chemicals aqueous dispersion effervescent tablet can directly be shed disintegration diffusion voluntarily in the paddy field in use, also can drop in the sprayer to spray in the crop target after the disintegration dispersion.
The pesticidal preparations of China is mainly missible oil and pulvis at present; Because missible oil uses a large amount of chemical solvent-environment and user are caused very big injury like toluene, xylol etc.; Pulvis is then because its serious drift of flying upward is particularly serious to user's injury, the metering difficulty when these two kinds of formulations also exist packing to use; And the aqueous dispersion effervescent tablet is owing to have given configuration, accurately monolithic weight, solvent-free, nothing drift, easy to use; Having simultaneously foaming boiling, disintegration fast, higher suspension rate and dispersive property again, is a kind of environmentally friendly pesticides new formulation, has become the frontier that current pesticidal preparations develops rapidly.
Agricultural chemicals aqueous dispersion effervescent tablet generally is made up of pesticide original medicine, acid source, carbon dioxide source, surfactant, free-flow agent, binding agent, inert filler etc.; Like the patent No. 00107465.2, described in 200610104832.3; But most Pesticidal products are not to be exactly unstable to alkali to acid, very easily decompose, thereby cause the product poor chemical stability; The active ingredient degraded, result of use descends.
