Abstract

The invention discloses water-dispersible granules containing an efficient disintegrant. The water-dispersible granules are prepared from the following ingredients in percentage by weight: 0.1% to 80% of active ingredients of pesticides, 1% to 10% of humectant, 1% to 10% of dispersant, 0.1% to 10% of sodium carboxymethyl starch and the balance of filler. According to the water-dispersible granules containing the efficient disintegrant, the efficient disintegrant, i.e., the sodium carboxymethyl starch is introduced into the pesticide water-dispersible granules, thus, the disintegration performance of the pesticide water-dispersible granules can be effectively improved, and the active ingredients of the pesticides can be rapidly dispersed in water to form a uniform pesticide solution, so that the utilization ratio of the active ingredients of the pesticides is increased, and the user effect of the water-dispersible granules can be improved.

Description

A kind of water dispersible granules containing superdisintegrantes
Technical field
The present invention relates to field of pesticide preparation is and in particular to the formula composition of pesticide water dispersible granules in pesticidal preparations.
Background technology
Sodium carboxymethyl starch (CMS-Na) is also called CMS, is a kind of anion starch ether, is to be dissolved in cold water Electrolyte, proterties be white or yellow powder, odorless, tasteless, nontoxic, the hot easy moisture absorption.It is dissolved in water and form colloidal solution, right Light, thermally-stabilised, insoluble in organic solvents such as ethanol, ether, chloroforms, there is stronger water imbibition and dilatancy, energy in cold water Very fast bubble rises, and after absorbing water particle expansion and not dissolve, do not form colloidal solution, do not hinder the continuation of moisture to penetrate into and impact The disintegration further of grain, is very outstanding solid pharmaceutical preparation disintegrant.
Water dispersible granules are a kind of pesticides new formulations of the exploitation eighties in last century, because its security is good, without organic molten Agent, no dust, packaging, transport, easy to use the advantages of developed rapidly.One as novel agrochemical environmental protection formulation important Developing direction, water dispersible granules have become the leading formulation of agricultural chemicals of recent domestic.
Pesticide water dispersible granules must be granulated by mediating the modes such as extruding, eddy flow fluidisation in process of production, leads to it Need disintegration in water could be used for spraying, so disintegrating property is pesticide water after forming homogeneous suspension in use One important indicator of dispersible granule, will lead to pesticide active ingredient can not play its medicine well if disintegrating property is poor Effect.The introducing of sodium carboxymethyl starch will can be effectively improved the disintegrating property of pesticide water dispersible granules so that pesticide active ingredient energy Quickly it is dispersed in water and forms homogeneous liquid, thus improving the utilization rate of pesticide active ingredient and being improved it using effect Really.
Content of the invention
The invention provides a kind of pesticide water dispersible granules containing superdisintegrantes, can effectively improve agricultural chemicals moisture Shot agent effectively raises agriculture in the disintegrating property in water so that pesticide active ingredient can rapidly and uniformly be distributed in water The utilization rate of pharmaceutically active ingredient simultaneously can significantly improve its drug effect.
The present invention is achieved through the following technical solutions：A kind of water dispersible granules containing superdisintegrantes, by following heavy The group of amount percentage is grouped into：Pesticide activity component 0.1%-80%, wetting agent 1%-10%, dispersant 1%-10%, carboxylic first Base sodium starch 0.1%-10%, filler complements to 100%.
Described pesticide activity component is Difenoconazole, dimethomorph, metalaxyl, imidacloprid, Acetamiprid, methylamino AVM hereinafter The mixing of one of rhzomorph or two kinds.
Described wetting agent is lauryl sodium sulfate, pull open powder, APES, phenethyl phenol polyoxyethylene The mixing of one or more of ether, butanedioic acid sulfonate, AEO.
Described dispersant is naphthalene sulfonate, sodium lignin sulfonate, calcium lignosulfonate, APES, benzene second In base phenol polyethenoxy ether, butanedioic acid sulfonate, neopelex, polycarboxylate, AEO one Plant or several mixing.
Described filler be one of fine particle calcium carbonate, diatomite, bentonite, kaolin, sepiolite, cornstarch, ammonium sulfate or Several mixing.
A kind of preparation method of water dispersible granules containing superdisintegrantes of the present invention：(1) pesticide activity is become Divide, wetting agent, dispersant, sodium carboxymethyl starch, filler carry out ultra micro air-flow crushing and female powder is obtained after mixing；(2) by agriculture It is obtained containing superdisintegrantes after the operations such as pharmaceutically active ingredient female powder is by adding water, mediating, extruder grain, drying, screening Pesticide water dispersible granules
The invention provides a kind of pesticide water dispersible granules containing superdisintegrantes, pesticide water can be effectively provided to disperse The using effect of granula, improves the utilization rate of pesticide active ingredient, can effectively reduce usage amount in agricultural production for the agricultural chemicals. Be conducive to the sustainable development of modern agriculture.
