Description

A kind of farm chemical emulsion preparation
Technical field
The present invention relates to a kind of farm chemical emulsion preparation, especially a kind of to people and crop safety height, environment amenable farm chemical emulsion preparation.
Background technology
Missible oil is one of basic formulation of agricultural chemicals tradition, compare with other formulations of pesticide, advantage such as missible oil has that active constituent content is higher, excellent storage stability, manufacture craft are simple, and in the missible oil owing to contain a large amount of organic solvents, make soup wetting on crop, polypide and weeds easily, opening up, the easier medicament that makes is penetrated in crop, polypide and the weeds body, therefore has better control efficiency.
But, produce emulsifiable concentrate pesticide and need use a large amount of organic solvents, mainly contain aromatic hydrocarbon solvent and N such as benzene,toluene,xylene, dinethylformamide (DMF), methyl alcohol isopolarity solvent, wherein the annual consumption of aromatic hydrocarbon solvent is up to ten thousand tons of 20-30, and it is low, inflammable and explosive and to shortcomings such as human and environment toxicity height, after these organic solvents enter environment along with the sprinkling of agricultural chemicals that these solvents have a flash-point, not only can cause severe contamination, also can damage health environment.
The order that Environmental Protection Agency USA (EPA) once successively decreased according to toxicity, harmfulness and management intensity with agricultural chemicals with solvent and other auxiliary agent be divided into 1,2,3,4A, 4B five big classes, wherein 1 class is to be proved there are harm in human health and environment, comprise the material of some carcinogens, neurotoxin, chronic toxicity material, harm reproduction and environment is had the material of pollution, as N, dinethylformamide, aniline, carbon tetrachloride, chloroform, dimethyl sulfoxide (DMSO), trichloro-ethylene etc.; 2 classes are to be necessary to carry out auxiliary agent toxicity test, that genotoxic potential is arranged, as toluene, cyclohexanone, dimethylbenzene, phenol, nonyl phenol etc.; 3 classes are the still indefinite materials of some toxicity, as D-hesperidene, N-Methyl pyrrolidone, N-octylpyrrolidone, turpentine oil, benzoic acid, nicotinic acid etc.; The 4A class is low-risk, comprises inert substance and those materials as food additives, as acetate, soya-bean oil, corn oil, White Mineral Oil, glycerine, oleic acid etc.; Some may be poisonous in the 4B class, but under specific service condition public health and environment are not had adverse effect, as australene, propane diols, isopropyl alcohol, ethanol, n-butanol etc.
1992, U.S. government put into effect the regulation of organic solvents such as forbidding toluene, dimethylbenzene in pesticidal preparations, and after this, European countries have also put into effect similar regulation in succession; By the end of in February, 2006,38 kinds of organic solvents that use in the Pesticidal products such as China Taiwan agricultural commission paraxylene, aniline, benzene, carbon tetrachloride, trichloro-ethylene management of having carried out limiting the quantity of, the content of dimethylbenzene, cyclohexanone can not surpass 10% in the agricultural chemicals finished product, dimethyl formamide and methyl alcohol should be less than 30%, and the content of ethylbenzene can not surpass 2%.
Along with the structural adjustment of National Development and Reform Committee's increasing to formulations of pesticide product, the output of missible oil product is compressed, and agricultural chemicals enterprise presses for to be sought efficient soluble additive environmentally friendly, that toxicity is low, easy degraded, renewable resources are derived and replace petrochemical industry series products or derivatives thereof.In existing patent documentation, existing report adopts vegetable oil or its derivative to use as pesticide solvent, and as adopting soybean oil, corn oil, rapeseed oil, cottonseed oil, soybean oil methyl esters etc., but these greases all exist with the people and strive food, the more high shortcoming of price.
In view of this, the necessary farm chemical emulsion preparation that a kind of safety, environmental protection are provided.
Summary of the invention
The objective of the invention is to: the farm chemical emulsion preparation that a kind of safety, environmental protection are provided.
The applicant attempts and the experiment discovery through a large amount of, australene in the plant resource solvent, D-hesperidene, Jatropha curcas oil methyl esters can use as solvent in emulsifiable concentrates for agricultural chemicals, it can substitute original other non-environmental protection soluble additives such as aromatic hydrocarbons organic solvent fully, and pesticide activity component is had significant synergies.In view of the above, the invention provides a kind of farm chemical emulsion preparation, it comprises pesticide activity component 1%~70%, stabilizing agent 0~8%, cosolvent 1%~25%, emulsifier 5%~20% and plant resource solvent surplus, described plant resource solvent is one or more in australene, D-hesperidene, the Jatropha curcas oil methyl esters, and aforementioned percentage all is mass percent.
The D-hesperidene is a kind of monocyclic terpene ene compound that extensively exists in the natural plant essential oils, chemical name is D-1-methyl-4-(1-methyl ethylene) cyclohexene, claim limonene, dipentene again, burning-point is 48 ℃, it is the good plants essential oil of a kind of solubility property, be mainly derived from rutaceae etc., all contain the D-hesperidene in a lot of plants such as oranges and tangerines, vegetables.It can not had teratogenesis, carcinogenic, mutagenic potentiality to the mankind by microbial decomposition, has been assert by FDA (Food and Drug Adminstration) to can be used as food additives.
Australene is terebinthine main component, and chemical name is 2,6,6-trimethyl-dicyclo (3.1.1)-2-heptene, and flash-point is 33 ℃, is mainly derived from pinaceae plant, the dry fruit content of Oleaceae plant is also higher.
The little seeds of a tung oil tree also claim little tung oil tree, Jatropha curcas (Jatropha curcas L.), are euphorbia plants, and the whole world has 200 kinds approximately.In the torrid areas, cultivated area is wider in China cultivation or semi-wild, and resource is than horn of plenty.According to the study, the dry fruit output of the wild little seeds of a tung oil tree is 4500-12000kg/hm2, can extract the Jatropha curcas oil that processes about 2700kg, and its methylate Jatropha curcas oil methyl esters only uses as a kind of biofuel at present.The processing cost of one ton of Jatropha curcas oil methyl esters of present every production is no more than 4500 yuan, compares with the vegetable oil of present use to have good development potentiality.
