Abstract
A slowly-releasing microemulsified aerosol-type insecticide is prepared from tetramethrin, pyrethroid, synergist, water-soluble high-molecular slowly-releasing agent, emulsifier, softened water and propellant through proportional mixng, loading in cans, aerating and installing nozzle. Its advantages are quickly taking its effect, durable acting, high safety and stability.
Description
The present invention relates to micro emulsion aerosol insecticidal preparation of a kind of health field application and preparation method thereof, belong to the hygienic insecticide technical field.
In recent years, aerial fog pesticide is used by people more and more.At present, the employed aerial fog pesticide of people mostly is the oil base aerosol greatly, they are many be solvent with organic solvent (deodorized kerosine), higher owing to its contained volatile organic compounds (Vocs), exist contaminated environment, inflammable, have excitant and smell to make us insufferable shortcoming.Therefore, many countries should be used as certain limitation to the oil base aerosol.For addressing this problem, people's development and production successively multiple be the aerial fog pesticide of solvent with water, but many because its liquid medicine stability is relatively poor, infiltration capacity is low, formulation rate is big, still can not satisfy people's instructions for use.In addition, above-mentioned aerial fog pesticide is as quick-acting formulations, its active component is owing to losing with fast speeds drift, evaporation and degraded in the medicine liquid spray process, so need dispenser repeatedly, bring problems such as air, water, food, environmental pollution and residual hazard and pesticide resistance, and its complex manufacturing technology, in blending process, need heat and stir, charging rate is had strict demand, and the required reaction time is long, so need the new water base aerial fog pesticide that addresses the above problem of development.
The object of the invention is to overcome above-mentioned shortcoming of the prior art and a kind of safe, economic microemulsified slow-releasing insecticide as aerosol and preparation method thereof is provided, and makes its effect to insect have quick-acting and lasting effect, to reduce environmental pollution and cost of manufacture.
The objective of the invention is to be achieved through the following technical solutions:
A kind of microemulsified slow-releasing insecticide as aerosol comprises (weight proportion) in the composition: tetramethrin 0.2-0.6, pyrethroid 0.4-0.8, synergist 0.8-1.8, water-soluble high molecular slow-release agent 0.5-5.0, emulsifier 8.0-20, demineralized water 60-85, propellant.
Above-mentioned microemulsified slow-releasing insecticide as aerosol, described pyrethroid can be chosen one or more in permethrin, cypermethrin, decis, the alkynes third chrysanthemum ester:
Above-mentioned microemulsified slow-releasing insecticide as aerosol, described synergist can be oxidation pepper butyl ether (S
1) or Octachlorodipropyl Ether (S
2):
Above-mentioned microemulsified slow-releasing insecticide as aerosol, described emulsifier can be Emulsifier EL-60 or APEO;
Above-mentioned microemulsified slow-releasing insecticide as aerosol, described propellant is a Compressed Gas, as compressed air, compression N
2Or compression CO
2The addition of described propellant is that aerosol jar internal pressure is to 5-6Kg/cm
2
The preparation method of microemulsified slow-releasing insecticide as aerosol of the present invention comprises following operation:
(1). the normal temperature batching: component and weight proportion are: tetramethrin 0.2-0.6, pyrethroid 0.4-0.8, synergist 0.8-1.8, water-soluble high molecular slow-release agent 0.5-5.0, emulsifier 8.0-20, demineralized water 60-85;
(2). tinning: above-mentioned each component is packed in the aerosol jar;
(3). inflation, dress shower nozzle: charge into propellant in the aerosol jar, extremely a jar internal pressure is 5-6Kg/cm
2, at the jar mouth shower nozzle is installed then.
The preparation method of above-mentioned microemulsified slow-releasing insecticide as aerosol, the described propellant that charges in the aerosol jar is a Compressed Gas, as compressed air, compression N
2Or compression CO
2
The preparation method of above-mentioned microemulsified slow-releasing insecticide as aerosol, in the described tinning operation, the material amount of packing in the aerosol jar accounts for the 50%-65% of aerosol tank volume.
The present invention has simplified the manufacture craft of preparation, need not heat and stir in blending process, to the charging rate no requirement (NR), has improved production efficiency greatly.
Pyrethroid in the microemulsified slow-releasing insecticide as aerosol component of the present invention is a lethal agent; Tetramethrin is a knock down agent; The synergist that is added can reach the purpose that strengthens insecticidal effect by the activity that suppresses to separate toxenzyme in the insect bodies; Water-soluble high molecular slow-release agent can be selected starch, gelatin, gum Arabic, lecithin, CMC, polyvinyl alcohol, polyethylene glycol, polyvinylpyrrolidone etc. for use, the rate of release of control medicament, form diaphragm in spraying the interface, oxygen, water, microorganism etc. make the medicament lasting period prolong, reduce dosage to the decomposition of active ingredient in the environment to reduce; The purpose that adds emulsifier has been the micro emulsion effect, can select polyoxy ion castor oil or APEO for use.
Compared with prior art, microemulsified slow-releasing insecticide as aerosol of the present invention has following advantage: the first, the effect of insect is had quick-acting and lasting effect: to fly, roach KT
502-3min, residual spray lasting period 2-3 month; The second, liquid medicine stability is good: (100 times of acceleration of gravity) centrifugal not phase-splitting, not stratified at a high speed, the long-term homogeneous phase transparent of placing under 0 ℃ of-40 ℃ of condition: the 3rd, economy safe in utilization: with water is matrix, do not fire not quick-fried, to the rat acute per os, suck LD
0＞20000mg/Kg (m
3); The 4th, obvious environment benefit: spray tasteless, non-stimulated, harmless to crops such as human body and flowers and trees.
The present invention has simplified the manufacture craft of preparation, compares with other insecticidal preparation, need not heat and stir in blending process, to the charging rate no requirement (NR), has improved production efficiency greatly, and cost is low, and is easy to use.
By the following examples, the invention will be further described.
