Abstract
An aquatic emulsion of copper abietate for preventing the frequently encountered diseases of fruit trees and vegetables is prepared from copper abietate, solvent, emulsifier, anti-freezing agent and water through dissolving and homogenizing.
Description
Technical field
The invention belongs to pesticide field, specifically aqueous emulsion of copper rosinate and method for making thereof.
Background technology
Copper rosinate belongs to rosin (perfume (or spice)) acid and makes ground copper organic acid bactericide with inorganic mantoquita reaction, and its structure is as follows: [CH
3(CH
2)
4CH=CHCH
2CH=CH (CH

7COO]
2Cu.Copper rosinate is soluble in benzene class, turpentine wet goods organic solvent, and the commodity preparation is generally missible oil, as 12% green newborn copper missible oil etc.This medicament has been inherited the advantage of copper series bactericidal agent as the organic copper series bactericidal agent, has characteristics, especially these medicament adhesivitys such as wide spectrum, efficient, low toxicity, non-resistant, cost are low, film forming is strong.Therefore the Chang Zuowei protective fungicide is used for the control of various crop fungi, bacteriosis.But cream preparation will consume a large amount of poisonous organic solvents, has both caused and has produced and the use cost increase, also easily causes environmental pollution and the tender fruit of tender leaf is produced poisoning, does not also meet the requirement of environmental protection agricultural chemicals development.Along with people's environmental consciousness strengthens day by day and to the requirement of green foods development, develops particularly important for the aqueous pesticide of oil with water.
Summary of the invention
The purpose of this invention is to provide a kind of aqueous emulsion of copper rosinate and method for making thereof.
Composition of the present invention and content (by weight) are
Copper rosinate 5～25%
Solvent 5～30%
Emulsifier 1～20%
Antifreezing agent 1～5%
Water adds to 100%
The used solvent of the present invention is selected from aromatic solvent such as toluene, dimethylbenzene, heavy aromatics, turpentine wet goods.The used emulsifier of the present invention comprises one or both or the two or more compounds in alkylphenol polyoxyethylene series, agricultural emulsifier NO series, castor oil polyoxyethylene ether series, phenethyl phenol polyethenoxy ether formaldehyde condensation products, the dodecyl benzene sulfonate.(as the QK-7 emulsifier).
The used antifreezing agent of the present invention comprises ethylene glycol, propane diols, urea etc.
Be applicable to that water of the present invention is running water, deionized water.
Method for producing aqueous emulsion of the present invention is: earlier with the copper rosinate dissolution with solvents, add emulsifier and stir evenly, again with antifreezing agent and water adding and mix, normal temperature high-speed stirred 30～60 minutes forms finely disseminated aqueous emulsion.Measure the product average grain diameter below 20 microns with the particle size distribution test instrument.
The outward appearance of aqueous emulsion of the present invention is a blue look opaque emulsion, because organic solvent content is low, nonflammable, produces, stores and transports safety, and environmental pollution is little, toxicity is low, belongs to the green non-pollution bactericide.Through evidence, aqueous emulsion of the present invention has excellent preventive effect to various crop downy mildew, eqpidemic disease etc., especially outstanding to downy mildew of garpe, pepper anthracnose, epidemic disease preventive effect, alternative bordeaux mixture control apple three big diseases have advantages such as preventive effect height, easy to use, safe, non-resistant.
Embodiment 1
Select following prescription:

500# 5％
op-8 3％
Propane diols 3%
Water adds to 100%
Production method is with embodiment 1, and the product average grain diameter is 1.2 microns.
Embodiments of the invention 1～3 sampling was stored 14 days at 54 ± 2 ℃, stored 7 days down for 0 ℃, its outward appearance still is the Lan Se emulsion that can flow, average grain diameter is respectively 1.2 microns, and 1.5 microns, 1.6 microns, viscosity is respectively 210mpas, 253mpas and 285mpas, with no significant difference before the storage.800 times of the diluted samples that embodiment 3 is made are prevented and treated downy mildew of garpe, contrast with 700 times of liquid of commercially available 70% mancozeb wettable powder, behind the medicine 10 days preventive effects the former be 87.2%, the latter 73.6%.The preventive effect of aqueous emulsion of the present invention obviously is better than 70% mancozeb wettable powder.
