Abstract
The invention discloses a kind of effervescent table as agricultural chemical and preparation method thereof, the weight percent of effervescent tablet each component of the invention is：Pesticide active ingredient 0.01% 50%, acid source 10% 40%, carbon dioxide source 10% 40%, diffusant 1% 10%, binding agent 0.1% 5%, filler supplies 100%.The present invention expands effervescent technique in the application range of pesticide field, can significantly improve the drug effect of active ingredient by the improvement to traditional effervescent table as agricultural chemical production technology.
Description
Technical field
The present invention relates to field of pesticide preparation, and in particular to effervescent table as agricultural chemical and preparation method thereof.
Background technology
Effervescent tablet technology is to be widely used in a kind of drug preparation technique of medicine and pesticide field, it and conventional tablet
Difference, in that it also contains gas-producing disintegrant, when effervescent tablet be put into drinking-water in after, in the effect of gas-producing disintegrant
Under, a large amount of bubbles (carbon dioxide) are generated at once, tablet is made to be disintegrated and melt rapidly, and medicine can also be made by being disintegrated the bubble of generation sometimes
Piece rolls up and down in water, it is accelerated to be disintegrated and melt.By the active ingredient of the effervesce effect drug of medicament in itself more
Uniformly it is distributed in liquid or paddy field.
Traditional effervescent tablet manufacturing technology is generally dry powder sheeting or half dry powder sheeting, the effervescent tablet pressed out in this way
In the active ingredient uniformity it is poor, its effervesce effect can also have a greatly reduced quality after entering water, influence active ingredient and play its effect.This hair
It is bright by being improved to tableting processes, by acid source and carbon dioxide source decomposition be granulated, then be mixed in a certain ratio laggard
Row tabletting so that active ingredient, acid source, carbon dioxide source can be uniformly distributed, and significantly improved the effervesce effect of tablet, made
Obtaining active ingredient can more uniformly be distributed, and improve its drug effect.

The filler is kaolin, bentonite, attapulgite, cornstarch, sepiolite, microcrystalline cellulose, talcum powder, silicon
The combination of one or more of diatomaceous earth, white carbon, magnesium stearate, lactose.
A kind of preparation method of effervescent table as agricultural chemical of the present invention：By acid source, carbon dioxide source respectively with pesticide activity into
Divide, be granulated after the mixing of diffusant, binding agent, filler, respectively obtain sour grain, alkali grain；Again by sour grain and alkali grain according to certain ratio
Tabletting obtains effervescent table as agricultural chemical after example mixing.
The present invention expands effervescent technique answering in pesticide field by the improvement to traditional effervescent table as agricultural chemical production technology
It with range, can significantly improve the drug effect of active ingredient.
