Abstract
Permethrin (0.3%), cyphenothrin (0.2%), oxypiperonyl butoxide (0.5%), Tween-80 (1.0%), Span-80 (0.3%) and glycol (2.0%) are fully mixed, under the condition of stirring the deionized water containing dissolved acacia (0.5%) is added, then heated to 50-60 deg.c while stirring to convert phase (from W/O to O/W) until it is made into transparent state, cooled, then the oxalic acid is used to regulate pH to 5-6 to obtain the invented water-based sanitary pesticide microemulsion. The time of whole technological proces sis about I hr., stirring speed is 100 r/min., and its operation is convenient, and its reaction condition is moderate, and its stability is good.
Description
The present invention relates to the up-to-date manufacture method of a kind of water-based micro pesticide emulsion.
With water is the aqua type hygienic insecticide of solvent, can not only reduce the production cost of insecticide significantly, reduce the pollution of organic solvent, weaken excitant the human respiratory tract to environment, and aqua type do not fire, and improved the safety in insecticide production, accumulating and the use.From the eighties, the exploitation of aqua type hygienic insecticide becomes the main trend of Future Development in the world.The present hygienic insecticide of China is still based on organic solvent type, on the one hand because the organic solvent type production technology is ripe relatively, environmental issue also is not subjected to enough attention, on the one hand because due to the intermiscibility of each component and stability problem are difficult to satisfactorily resolve in the water aqua type product yet.
The present invention is intended to realize a kind of easy manufacture method of water-based micro pesticide emulsion of stable transparent.
Material proportion that the present invention selects for use and effect are as follows:
Component (W) % effect
Permethrin 0.3 desinsection
High gram dung beetle 0.2 desinsection
Gum Arabic 0.5 slowly-releasing
Oxidation of piperonyl butoxide 0.5 synergy
Tween-80 1.0 emulsifications
Si Ben-80 0.3 emulsification
Ethylene glycol 2.0 auxiliary agents
The oxalic acid trace assistant
Water 95.2 solvents
Manufacture process and study on the stability: permethrin, high gram dung beetle, oxidation of piperonyl butoxide, Tween-80, Si Ben-80, ethylene glycol are fully mixed, under agitation add the deionized water that is dissolved with gum Arabic, ℃ of-60 ℃ phase inversions of warming while stirring to 50 are (by W/O → O/W), until transparent, it is 5-6 that pH is transferred with oxalic acid in the cooling back, and whole technical process needs 1h, mixing speed 100r/min approximately, easy to operate, mild condition.This product is through heat storage (50 ℃, a year), and cold storage (0 ℃, a year) is investigated, and still keeps the clear microemulsion state, and it has good stability.
Claims (3)
1, water-based micro pesticide emulsion selected material and quality proportioning (permethrin: high gram dung beetle: gum Arabic: oxidation of piperonyl butoxide: Tween-80: Si Ben-80: ethylene glycol: water=0.3: 0.2: 0.5: 0.5: 1.0: 0.3: 2.0: 95.2) in making.
2, the technological process of water-based micro pesticide emulsion manufacturing and condition (are fully mixed permethrin, high gram dung beetle, oxidation of piperonyl butoxide, Tween-80, Si Ben-80, ethylene glycol, under agitation add the deionized water that is dissolved with gum Arabic, warming while stirring to 50 ℃-60 ℃ of phase inversions, until transparent, it is 5-6 that pH is transferred with oxalic acid in the cooling back, mixing speed 100r/min).
3, the pH value scope (5-6) of water-based micro pesticide emulsion.
