Abstract
An agricultural phytocide emulsion is prepared from (sym-triazabenzene) ametryne (26-30%), (amide) ethoxalylamine (10-14%), disperser (2-5%), emulsifier (5-10%), penetrant (0.1-1%), anti-freezing agent (3-7%), cosolvent (3-7%) and water (rest), and features simple process, and high efficacy.
Description
The present invention relates to a kind of production method of agricultural herbicide, specifically a kind of preparation method of " Youyi " suspension emulsion.
Atrazine is widely used in the control of the big Tanaka weeds of corn as a kind of weed killer herbicide commonly used, but atrazine is outstanding to the preventive effect of broad leaved weed, preventive effect to monocotyledon weed is poor, and the longevity of residure is long, easily stubble crops is thereafter produced poisoning after using for many years.Acetochlor is a kind ofly to prevent and kill off the big Tanaka's monocotyledon weed of corn and broad leaved weed is not had the weed killer herbicide commonly used of preventive effect, and the longevity of residure is moderate.In order to get the strong point of atrazine and Acetochlor two weed killer herbicides, improve killing of the big field weed of corn and remove effect, reduce production costs, generally use the formulation that is mixed of atrazine and Acetochlor two weed killer herbicides both at home and abroad, as No. 92109142.7 application of Chinese patent, name is called " manufacture craft of herbicide-herbicide suspension emulsion ", No. 93100089.0 application of Chinese patent, name is called " suspended emulsion of sym-triazbenzene-amide herbicides ", and above-mentioned two parts of files disclose atrazine (s-triazine), Acetochlor (amide-type) and other additives such as polyoxyethylene nonylphenol ether-13, OP-10,0201,0203,34
#, 2201,1602, pentasodium triphosphate of dispersing agent sodium lignin sulfonate, NNO, calcium lignosulfonate, proportion conditioning agent isopropyl alcohol, urea, thickener polyvinyl alcohol, CMC, xanthans, bentonite, white carbon, stabilizing agent tbp, triphenyl phosphite, BHT, bleeding agent gathers sorbic acid fat BO, penetrant t, M-PYR01, lactones BLO, the formulation that is mixed of compositions such as antifreeze glycol, polyethylene glycol, glycerine.
The purpose of this invention is to provide a kind of preparation method who uses a kind of " Youyi " suspension emulsion that raw material type is few, the simple cost of technology is low, herbicidal effect is good.
The objective of the invention is to realize in the following manner, main material is the atrazine generally to use both at home and abroad still, and (industrial goods active ingredient is＞90%), Acetochlor (industrial goods active ingredient＞80%) selects for use emulsifier to be: OP-10,809,500 in addition
#, two kinds of mixtures in 1602,2201.Dispersant is: two kinds of mixtures among calcium lignosulfonate, sodium lignin sulfonate, the NNO, and bleeding agent is a sodium succinate, cosolvent is a methyl alcohol.Suspension stabilizer is: two kinds of mixtures in xanthans, CMC, polyvinyl alcohol, white carbon, the diatomite, antifreezing agent is: a kind of in ethylene glycol, glycerine, the polyethylene glycol.Through coarse crushing and the sand mill particle mean size 2-3 micron that makes in small, broken bits, the " Youyi " suspension emulsion with polymolecularity high stability, this preparation technology compares with prior art, has simplified production technology, has reduced production cost, and its performance but is better than other like products.
The concrete preparation technology of the preparation method of " Youyi " suspension emulsion of the present invention is as follows;
Contain (equal three nitrogen are stupid) atrazine 26-30%, (amide-type) Acetochlor 10-14%, dispersant 3-5%, emulsifier 5-10%, bleeding agent 0.1-1%, suspension stabilizer 0.5-2%, antifreezing agent 3-7%, cosolvent 3-7% in this suspended emulsion, surplus is a water.Emulsifier is: OP-10,809,500
#, two kinds of mixtures in 1602,2201.Dispersant is: two kinds of mixtures among calcium lignosulfonate, sodium lignin sulfonate, the NNO, and bleeding agent is a sodium succinate, cosolvent is a methyl alcohol.Suspension stabilizer is: two kinds of mixtures in xanthans, CMC, polyvinyl alcohol, white carbon, the diatomite, antifreezing agent is: a kind of in ethylene glycol, glycerine, the polyethylene glycol.
During making, the first step: the atrazine 26-30%, 1602 emulsifier 2-5%, OP-10, white carbon 0.5-2%, xanthans 0.1-0.2%, NNO2-5%, the bleeding agent 0.1-1% that get weight percentage, surplus is a water, add coarse crushing in high speed shears or the ball mill, squeeze into then that in small, broken bits in the sand mill to put into storage tank to the 2-3 micron as the A material standby.
Second the step: percentage composition is got the Acetochlor of 10-14%, the methyl alcohol of 5-7 by weight, 809 emulsifier of 2-5% and 0.5% 500
#Emulsifier is added to heat in the reactor and was stirred 30 minutes, and temperature is controlled at 40-60 ℃, and reducing to room temperature after reaction finishes, to put into storage tank as the B material standby.
The 3rd step: A material that will be standby and B material are squeezed in the high speed homogenizer homogenizing taking-up in 30 minutes simultaneously and are packed and can sell.
