Description
Technical field
The invention belongs to technical field of pesticide, be related to a kind of two villaumite containing diquat dibromide can glue and preparation method thereof.
Background technology
Diquat dibromide (diquat) is the bipyridyliums steriland herbicide of quick-acting contact killing types, is that the current whole world is most widely used
One of general herbicide products, global marketing and usage amount are only second to glyphosate and paraquat, occupy the 3rd big total weed control
Agent.
Paraquat is disabled or limit the use of on European Union and other places due to toxicity problem, and diquat dibromide is as having and paraquat
The herbicide products of the identical mechanism of action and the mode of action are able to Rapid Popularization use, have gradually filled up what paraquat was available
Market.
Although the toxicity of diquat dibromide, well below paraquat, diquat dibromide does not also detoxify effectively medicament, therefore, one
After diquat dibromide poisoning is wrongly taken or swallowed intentionally to denier, in the case where not obtaining timely, correct rescue, still it can be made to human or animal
At serious injury, or even can therefore get killed.
In order to improve the safety of diquat dibromide, especially to the safety of the mankind, it is ensured that accelerate enemy's grass under the premise of safety
It quickly promotes the use of soon, develops a kind of injury that can significantly reduce diquat dibromide to human or animal, improve the peace of diquat dibromide preparation
Full property new formulation is particularly necessary.
A kind of diquat dibromide nonaqueous solvent dosage form --- the water-soluble ointment that patent 201110281641.5 is mentioned, still, master
It is diquat dibromide dibromo salt to want ingredient, although being all the salt of diquat dibromide, two villaumite of diquat dibromide and diquat dibromide dibromo salt are eventually
It is 2 kinds of different compounds, there is larger difference in nature in physics and chemistry.Currently, there are no the phases of two villaumite of diquat dibromide on the market
Formulation products are closed, are occurred typically without novel forms products such as the solvable jellies of two villaumite of diquat dibromide.
Invention content
The present invention be directed to above-mentioned technical problem a kind of two villaumite containing diquat dibromide is provided can glue and its system
Preparation Method.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of two villaumite containing diquat dibromide can glue, the mass percentage of two villaumite of diquat dibromide is 1-40%, surface
The mass percentage of activating agent is 10-20%, remaining is auxiliary material.
In some preferred technical solutions：The mass percentage of two villaumite of diquat dibromide is 10-40%.
In some specific technical solutions：The surfactant is selected from neopelex, dodecyl
Sodium sulphate, methyl sodiosul foaliphatate, sodium sulfate of polyethenoxy ether of fatty alcohol, alcohol ether Disodium sulfosuccinate, aliphatic acid sulphur alkane

Kind.
In some more specific technical solutions：The surfactant is selected from neopelex, dodecane
Base sodium sulphate, methyl sodiosul foaliphatate, sodium sulfate of polyethenoxy ether of fatty alcohol, alkyl phenol formaldehyde resin polyoxyethylene ether, the moon
Osmanthus amido propyl betaine, cocamidopropyl betaine, hexadecyltrimethylammonium chloride and octadecyl trimethyl chlorine
Change arbitrary 2~4 kinds in ammonium.
In some more preferably technical solution：The surfactant is selected from following combination：
It is lived by the surface that neopelex, lauryl sodium sulfate and sodium sulfate of polyethenoxy ether of fatty alcohol form
Property agent, parts by weight are followed successively by 1~3：4~12：5~15；
Or it is lived by the surface that lauryl sodium sulfate, methyl sodiosul foaliphatate and cocamidopropyl betaine form
Property agent, parts by weight are followed successively by 1~5：5~15：5~12；
Or by sodium sulfate of polyethenoxy ether of fatty alcohol, alkyl phenol formaldehyde resin polyoxyethylene ether, dodecanamide propyl beet
The surfactant of alkali and octadecyltrimethylammonium chloride composition, parts by weight are followed successively by:0.1~3：1~5：5~12：3
~8；
Or the surfactant being made of alkyl phenol formaldehyde resin polyoxyethylene ether and lauroylamidopropyl betaine, it is heavy
Amount number is followed successively by 10~25：1~8；
Or the surface of lauryl sodium sulfate, cocamidopropyl betaine and hexadecyltrimethylammonium chloride composition
Activating agent, parts by weight are followed successively by 0.1~3：5~15：5~12.
In technical solution of the present invention：It is described can glue to contain the triazole that mass percentage is 0.01-0.1% phonetic

A kind of above-mentioned two villaumite containing diquat dibromide can glue preparation method, this method is by the aqueous solution containing diquat dibromide
With stink agent, emetic and warning coloration, stir evenly；Surfactant is added later, after persistently stirring evenly, is formed high viscous
The solvable jelly of two villaumite of diquat dibromide of degree, lazy flow.
Beneficial effects of the present invention：
The present invention by diquat dibromide be processed into can glue, be not only able to effective less diquat dibromide preparation splashing calcination mankind or
The skin of animal, and can be low because of the advanced mobility of the present invention, it wrongly takes or the Impulsive amount of swallowing is low, and significantly reduce diquat dibromide
Security risk.
The present invention is selected the surfactant of special formulation to make, is had to diquat dibromide by the screening of surfactant formula
Sensitive and excellent thickening power, after complexed surfactant meets with two villaumite of diquat dibromide, it is rapid occur " micella transformation " and
Play good thickening power.Simultaneously complexed surfactant can also increase can glue meet water after dissolubility and dissolving speed
Degree, and there is apparent synergistic effect to diquat dibromide.
In terms of processing, composition of the invention, without containing the water-insolubles matter such as thickener or solid packing, processing method
It is identical as diquat dibromide aqua with production equipment, set of device can be shared with diquat dibromide aqua, thus, there is no the need of newly added equipment
It wants, production cost will not improve.
In use, the present invention has excellent water solubility and instant capacity, flexible and convenient to use, will not be brought to user
Unnecessary trouble, and its using effect is better than diquat dibromide aqua.
