The invention discloses a kind of chlortoluron and benthiocarb microemulsion, which belongs to herbicide field；Preparing the raw material that the product uses includes：Chlortoluron wettable powder 10.5 11.5%, benthiocarb 3.5 4.5%, acetone 15%, benzene sulfonic acid sodium salt 2%, water 68%, by blending under given conditions come finished product, the advantages of production method, is：Using common apparatus, simple for process, reaction condition is mild, pollution-free waste discharge, good product quality, chlortoluron has synergistic effect with benthiocarb compounding, after above-mentioned two kinds of herbicides and auxiliary material compounding, the significant effect of anti-weeding, which is higher than, is applied alone chlortoluron or benthiocarb, herbicidal effect greatly enhances, and the kind of herbicide further increases.
Description
Technical field
The invention belongs to herbicide field more particularly to the preparation methods of a kind of chlortoluron and benthiocarb microemulsion.
Background technology
Chlortoluron is a kind of selective inner sucting conduction type carbamide herbicides, and sterling crystallizes for no color or smell, and original powder is yellowish-brown
Color blocks of solid, is insoluble in water, nontoxic to honeybee to birds and fish low toxicity, is mainly absorbed by the root system of weeds, and has blade face
Action of contace poison is suppressed the transmission of weeds photosynthesis, makes weeds hungry and dead, 3 days after dispenser, weeds start in performance
Toxication shape, blade chlorisis, blade tip and the successive chlorosis of lobus cardiacus, whole strain in about 10 days or so are dried up and dead, the lasting period in the soil
70 days or more, it is mainly used for preventing amur foxtail, annual bluegrass, the annual gramineaes such as wild oat, Cyperaceae and big in dry crop
Most broad leaved weeds also have some effects to caput grass, hard grass.Benthiocarb also known as weed eradication are red, and appearance is weak yellow liquid, is dissolved in
Most organic solvents, in acid, stable under alkaline conditions, benthiocarb is broad-spectrum herbicide, has spy to rice terrace fescue, barnyard grass
Effect, can effectively prevent and kill off the annual grassy weeds such as Monochoria vaginalis, Sagittaria pygmaea, to rice, wheat, rape, peanut, soybean, cotton, corn,
The crop safeties such as sugarcane.Chlortoluron has synergistic effect with benthiocarb compounding, after above-mentioned two kinds of herbicides and auxiliary material compounding, prevents and kill off
The significant effect of grass is higher than chlortoluron or benthiocarb is applied alone, and herbicidal effect greatly enhances, and the kind of herbicide further increases.
The content of the invention
Present invention mainly solves the problem of be to provide a kind of chlortoluron and benthiocarb microemulsion, produce the product with chlortoluron
Wettable powder, benthiocarb, acetone, benzene sulfonic acid sodium salt, water are raw material, by blending under given conditions come finished product, life
Producing the raw material weight proportioning of soup processed that the product uses includes：Chlortoluron wettable powder 10.5-11.5%, benthiocarb 3.5-4.5%, acetone
15%th, benzene sulfonic acid sodium salt 2%, water 68%.
The present invention can be achieved through the following technical solutions：
（1）First the acetone of formula ratio is added in the first agitator tank, starts to stir under room temperature, the rotating speed of blender for 25 turns-
30 revs/min, while stirring add in formula ratio benthiocarb, be stirred to react 0.4-0.5 it is small when.
（2）First the water of formula ratio is added in high-speed stirred tank, starts to stir under room temperature, the rotating speed of blender is 20
Turn -25 revs/min, add in chlortoluron wettable powder, the benzene sulfonic acid sodium salt of formula ratio while stirring, stir to chlortoluron wettable powder
Agent, benzene sulfonic acid sodium salt all after dissolving, heighten the rotating speed of blender in fast agitator tank as 200-210/ points, will slowly be dissolved in acetone
Benthiocarb add in high-speed stirred tank, be stirred to react 0.6-0.7 it is small when after obtain finished product.
The present invention further technical solution be：
The purity of the chlortoluron wettable powder is 40%, the purity of benthiocarb is 80%.
Step（1）, step（2）The room temperature is 2-35 DEG C.
The beneficial effects of the invention are as follows：A kind of chlortoluron and benthiocarb microemulsion are provided, the advantages of preparation method is：
It is simple for process, environmental pollution is small, the reaction time is short, reaction condition is mild；The advantages of product is：Chlortoluron has with benthiocarb compounding
Synergistic effect, after above-mentioned two kinds of herbicides and auxiliary material compounding, the significant effect of anti-weeding, which is higher than, is applied alone chlortoluron or benthiocarb,
Herbicidal effect greatly enhances, and the kind of herbicide further increases.
