Abstract
The present invention relates to pesticide adjuvant, particularly to environmental protection type pesticide adjuvant which takes vegetable oil, cosolvents and surface active agents as raw materials. The raw materials and the content (by mass ratio) thereof are as follows: 100kg of vegetable oil, 0 to 50kg of cosolvents, and 5 to 55kg of surface active agents. The pesticide adjuvant can be prepared into different pesticide formulation with various dosage forms, such as emulsifiable solution, suspension, hot fog formulation, aerosol, tumble blending formulation, ultralow volume spraying agents, biocidal agents, acaricides, germicidal agents, disinfectant, sanitary pesticide and plant growth regulators. Due to the replacement of substituted benzene with vegetable oil, the pesticide adjuvant can reduce the requirements of petroleum resource and lower the cost of pesticide formulation. In addition, the pesticide adjuvant has better physical chemistry stability, expansive permeability, drift resistance, safety and integrative prevention than preparation that is prepared from substituted benzene.
Description
Technical field
The present invention relates to a kind of agricultural chemicals, especially relating to a kind of is the environmental protection type agricultural chemical auxiliary agent of raw material with vegetable oil, cosolvent, surfactant.
Background technology
Existing pesticidal preparations processing enterprise is numerous, in pesticidal preparations, is extensive use of insecticides adjuvant, and using maximum is to be the liquid preparation of auxiliary agent with substituted benzene (toluene, dimethylbenzene, benzene mixed).As everyone knows, substituted benzene (toluene, dimethylbenzene, benzene mixed) is the strong carcinogenic substance that the World Health Organization determines, is the maximum etiology that causes alpastic anemia (leukemia) and fetal congenital defective.Substituted benzene (toluene, dimethylbenzene, benzene mixed) is again a kind of inflammable and explosive Hazardous Chemical Substances, and its flash-point and explosion ratio are all very low, danger close all in pesticidal preparations processing and storage and transport process.Substituted benzene (toluene, dimethylbenzene, benzene mixed) is again important petrochemicals simultaneously, the substituted benzene that China is used for pesticidal preparations processing every year reaches few hundred thousand tonnes of, and poisonous, harmful solution of this few hundred thousand tonnes of is sprayed onto the field more, not only aggravate the anxiety of petroleum resources, and cause pollution ecotope.
In sum,, both wasted petroleum resources in short supply, polluted ecotope again, and made pesticidal preparations processing and accumulating bring potential safety hazard with substituted benzene (toluene, dimethylbenzene, benzene mixed) processing pesticidal preparations.Developed countries such as America and Europe have begun restriction and have forbidden with substituted benzene (toluene, dimethylbenzene, benzene mixed) processing pesticidal preparations, developed the novel form with the alternative substituted benzene (toluene, dimethylbenzene, benzene mixed) of water section such as aqueous emulsion, microemulsion, but to the agricultural chemicals of some easy hydrolysis and be not suitable for, and aqueous emulsion, microemulsion are all bigger to the consumption of surfactant and other macromolecular materials, and cost and process technology all are restricted.Even to this day, only have a small amount of specific activity higher, the kind that effective component content is low is processed to aqueous emulsion and microemulsion.Yet, owing in significant period of time from now on, also can't completely forbid the use of substituted benzene (toluene, dimethylbenzene, benzene mixed).Therefore the environment-friendly type auxiliary agent of developing a kind of alternative substituted benzene (toluene, dimethylbenzene, benzene mixed) is very necessary.
Publication number is that the application for a patent for invention of CN1095214A discloses a kind of preparation method of agricultural chemical auxiliary.It with fatty acid and hydramine be placed on the reaction pot heating, stir, cooling makes fatty alkanol amide, adds polyoxyethylene alkylphenol ether, pH regulator agent and deionized water heated and stirred again, cooling makes finished product.Publication number is the manufacturing process that the application for a patent for invention of CN1047011A discloses a kind of neutral insecticides adjuvant, comprise liquor type auxiliary agent production technology and powder-type auxiliary agent production technology, the former raw material is lignosulfonates (liquid state), after dodecyl benzene sulfonate and methyl alcohol mix, after staticly settling, the latter's raw material is sodium lignin sulfonate (powder), and neopelex (powder) and sodium carboxymethylcellulose (powder) mix, stir.Publication number is that the application for a patent for invention of CN1436458A discloses a kind of insecticides adjuvant and using method thereof that promotes that agricultural chemicals effectively utilizes.Insecticides adjuvant is made of excipient, surfactant and thinner.Said excipient is a polyvinyl alcohol, polyethylene glycol, polyethylene glycol oxide; Said surfactant is secondary octyl phenol polyethenoxy (a 10) ether, alkylphenol-polyethenoxy (10) ether, Nonyl pheno (10) ether (NP-10).
Summary of the invention
The objective of the invention is at using the problem that substituted benzene brought, substitute substituted benzene (toluene, dimethylbenzene, benzene mixed) with vegetable oil, it is poor to solve the vegetable oil compatibility, the technical barrier that emulsification is bad, providing a kind of is the environmental protection type agricultural chemical auxiliary agent of raw material with vegetable oil, cosolvent, surfactant.
Raw material of the present invention and be: vegetable oil 100, cosolvent 0～50, surfactant 5～55 by the content of mass ratio.Described vegetable oil is selected from rapeseed oil, cottonseed oil, soybean oil, tea oil, peanut oil, castor oil, palm oil, pine-tree oil, camphor tree oil, eucalyptus oil, tung oil, or has at least a in the vegetable oil of similar features.
Described cosolvent is selected from dimethyl formamide, ethanol, isopropyl alcohol, acetone, cyclohexanone, or has at least a in the material of similar features.
Described surfactant is selected from fatty alcohol-polyoxyethylene ether, alkylphenol polyoxyethylene, castor oil polyoxyethylene ether, phenethyl phenol polyethenoxy ether, Wan base Fen Jia Chuo resin APEO, calcium dodecyl benzene sulfonate, or has at least a of similar features.
The present invention can be used for preparing the pesticidal preparations that formulation is missible oil, oil suspending agent, thermal fog, aerosol, bucket mixture, ultra low volume spraying agent.
The present invention can be used for preparing insecticide, miticide, bactericide, disinfectant, hygienic insecticide, plant growth regulator.
Preparation method of the present invention is that said various raw materials are evenly mixed in reactor by said ratio, it is mixed with the medicine effective ingredient of being prepared to get final product then.
Compared with the prior art, the substantive distinguishing features and the marked improvement that have of the present invention is:
Vegetable oil derives from green plants, nontoxicly, harmless helps environmental protection.
Vegetable oil is a renewable resources, and alternative substituted benzene (toluene, dimethylbenzene, benzene mixed) processing pesticidal preparations can reduce the demand of pesticide producing to petroleum resources, and can make the peasant planting oil crop bring income, meets the industrial policy of country.
Vegetable oil is compared with substituted benzene (toluene, dimethylbenzene, benzene mixed), and under the situation of oil price rising all the way, its price has very big advantage, helps reducing the cost of pesticidal preparations, reduces farmer's burdens.
With the vegetable oil pesticidal preparations of auxiliary agent processing, its physical and chemical stability and opening up permeability, anti-drift, safety and integrated control effect and all be better than preparation with substituted benzene (toluene, dimethylbenzene, benzene mixed) processing.
