Abstract
The present invention relates to a method for preparing high-concentration pesticide emulsion and emulsifiable paste by using surfactant as dispersing agent. Adding appropriate surfactant as emulsifier into liquid pesticide raw material, and stirring to obtain emulsion. Or adding inorganic powder filler which does not destroy the activity of the original pesticide to prepare the emulsifiable paste. The cream or the cream does not contain water or organic solvent, and can reduce the pollution to the environment and the harm to crops in the preparation and the use. Compared with the existing emulsion, the emulsion can improve the effective content of pesticide, and is more convenient and safer to use and transport by changing the packaging form.
Description
The invention belongs to the preparation method of the formulations of pesticide.
In general; most pesticide original medicines all need be processed into certain preparation and can use; example emulsion, pulvis, wetting powder, granula etc.; so not only easy to use; and help to strengthen drug effect, alleviate poisoning, reduce toxicity, reduce and pollute; the protection natural enemy, thus reach the purpose of efficient, safety, economy.At present, a kind of formulation that former medicine processed and applied is maximum is an emulsion.
Now known have in water and hydrophilic solvent medium, make the spraying agent of outstanding emulsus with being insoluble in pesticide original medicine that solvent can not emulsification, as described in Japanese Patent Publication 46-20519 number, and with the oily organophosphorus insecticide with hydrophobic organic solvent, surfactant, the tackifier allotment makes the yolk yellow sauce shape of high concentration organic phosphorous insecticide oil-in-water type preparation, as described in Japanese Patent Publication 46-18514 number, also have indissoluble or the same thickener of water-fast pesticide original medicine, the aqueous suspension that stabilizing agent preservative and emulsifier etc. are mixed with is as described in Japanese kokai publication sho 58-124702.From the above present known pesticidal emulsifiable formulation of enumerating as can be seen, general emulsion all is furnished with a large amount of organic solvents or water.Join like this emulsion in, not only increased the effective content that unnecessary inert weight has reduced agricultural chemicals, and organic solvent in the preparation of emulsion and in using except that bringing the pollution to environment, return crop and bring harm.
Main points of the present invention have been to adopt a kind of new prescription, thereby make a kind of neither moisture brand-new formulation-agricultural chemical cream and milk extract that does not also contain organic solvent, have overcome the existing shortcoming of existing emulsion.
Particularly, the present invention has adopted liquid former medicine and suitable emulsifier, under the situation of room temperature or heating, and the fully mixed milk extract that gets; Perhaps add the inorganic powder filler that does not destroy pesticide activity again, make emulsifiable paste through allotment.
Under the normal temperature, an amount of emulsifiable paste or milk extract are added in the entry, stirring to be suitable for the emulsion of concentration.Pesticide original medicine is uniformly dispersed and meets instructions for use in the emulsion, can directly implement spraying operation.
The pesticide original medicine that is applicable to this law can be soluble in water, that be insoluble in water or water-fast liquid pesticide, as organic phosphors such as chrysanthemum fat, nuvacron, phosphamidon, flolimat, acephatemet such as Belmarks.According to purposes, pesticide original medicine can singly be used, also can be several composite, and by weight, its proportioning accounts for the 40-85% of emulsifiable paste, generally is not more than 60% of emulsifiable paste gross weight, accounts for about the 65-98.1% of milk extract.
Said emulsifier both can be an anionic surfactant, it also can be nonionic surface active agent, the perhaps mixture of the two, as Zhong Shan chemical plant, Nanjing produce or development 02030204, the emulsifier of the trade mark such as 0206B, according to agricultural chemicals character, can join by a kind of emulsifier list, also can be several composite, emulsifier generally can account for the 0.5-35 of the 1.9-35% milk extract weight of emulsifiable paste weight.
Said inoganic solids filler can be powder such as talcum powder, precipitated calcium carbonate, white carbon black, zeolite, diatomite, or other does not destroy the inorganic powder of pesticide activity.Particle size will account for more than 96% of filler sum in the part below 43 microns.Its addition is decided on the thickness of pesticide original medicine and emulsifier mixture in emulsifiable paste.Generally account for the 10-50% of emulsifiable paste weight.
Details are as follows to prepare the method for emulsifiable paste or milk extract by the present invention:
Take by weighing a certain amount of pesticide original medicine in beaker, as be the bigger former medicine of ratio of viscosities, can in 50 ℃ baking oven, heat a little time together with beaker, treat that former medicine becomes very easy flow after, take out and add a certain amount of emulsifier, stir rapidly then to reach abundant mixing, treat evenly after, leave standstill or on oscillator vibration to quicken froth breaking, obtained thing is the agricultural chemicals milk extract, as adding a certain amount of powder filler again, stir once more, leave standstill or froth breaking promptly gets agricultural chemical cream as preceding method.
Specific embodiment sees Table the 1:(umber by weight)
Annotate: the percentage under the pesticide original medicine is former medicine content.
Agricultural chemical cream and the test of milk extract heat storage stability.(seeing Table 2)
Claims (8)
1, with the surfactant is the method that dispersant prepares the high concentration agricultural chemical formulation, it is characterized in that the former medicine of liquid state and anion surfactant mixed and be mixed with milk extract or add the inorganic powder filler that does not destroy pesticide activity again, its particle diameter is total more than 96% less than 43 microns account for, make emulsifiable paste, said agricultural chemicals is insoluble, indissoluble, liquid insecticide soluble in water, can singly join, also can be composite, proportioning is as follows: (weight meter)
The agricultural chemicals milk extract
Former medicine: 65-98.1% emulsifier 1.9-35%
Agricultural chemical cream
Former medicine: 40-85% emulsifier: 0.5-35% filler: 10-50%
2, in accordance with the method for claim 1, it is characterized in that said pesticide original medicine refers to Belmark, nuvacron, phosphamidon, flolimat, agricultural chemicals such as acephatemet.
3, according to claim 1 and 2 said methods, it is characterized in that said surfactant can be the surfactant produced of Zhong Shan chemical plant, Nanjing as: the trade mark is 0204,0206B.
4,, it is characterized in that said inorganic powder filler refers to talcum powder, precipitated calcium carbonate, white carbon black, zeolite, diatomite according to claim 1 and 2 described methods.
