Description
Technical field
The present invention relates to agriculture chemical compounding agent and preparation method thereof, especially relate to a kind of by organophosphorus insecticide chlopyrifos and the composite a kind of agriculture chemical compounding agent that forms of chloro nicotinic insecticide thiophene worm quinoline and preparation method thereof.
Background technology
Under the influence of world today's " mankind will get along amiably and peacefully with the Nature " ideological trend; human sense of self-protection, living standard improve day by day; various countries have put into effect increasing pact, rules improve environment for human survival and food quality, and the development of chemical pesticide has been subjected to increasing restriction.And the environmental protection factor has become many countries and has limited a kind of means that his home made article enters domestic markets in international trade, the international market is more and more higher to the requirement of agricultural chemicals, this certainly will increase the research and development expense and the production cost of China's exported product, has also restricted the outlet of China's portioned product simultaneously.
Along with the increasing of pesticide producing to China's environment build-up of pressure, country has strengthened the discharging management to pollutant in the production process.State Environmental Protection Administration has worked out " insecticide pollution discharge standard ", and clearly regulation has been made in the discharging of agricultural chemicals enterprise 10 pollutants.National Development and Reform Committee also spells out, and in order to reduce environmental pollution and to preserve the ecological environment, should progressively substitute existing conventional dosage forms with the particularly water base chemical preparation of environmental protection novel form, is the trend of current pesticidal preparations development.
Therefore, China's agricultural chemicals enterprise more selections on product of still needing that want to get through the close siege.At present, environment-protection pesticide is just meeting rare opportunity to develop, compares with chemical pesticide, and environment-protection pesticide has following advantage: (1) is easily degraded in environment, is lacked residual or noresidue people, animal, beneficial organism low toxicity, does not have environmental issue; (2) replace organic solvent as main carrier with water, do not have the danger of catching fire, no unpleasant toxic odor, little to eye irritation, reduced pollution to environment, improved safety greatly to production, storing and user; (3) have good heat storage stability, cold cut stability and water dilution stability; (4) farming is originally low, and with respect to chemical pesticide, profit space is bigger; (5) energy savings.
In sum, face period of problems, exploitation and produce environment-protection pesticide bigger realistic meaning has just been arranged at current China chemical pesticide.

(2) make oil phase
By weight percentage chlopyrifos 8%～30% is added with solvent 5%～15% and be in the same place, be stirred to chlopyrifos and be dissolved in fully in the solvent, become even oil phase;
(3) make water
By weight percentage emulsifier 2%～8%, antifreeze 2%～10%, defoamer 1%～3% and water are added in and are mixed together dissolving fully, one-tenth homogeneous water;
(4) mix shearing
The above-mentioned oil phase for preparing is joined aqueous phase, and high speed shear adds the thiophene worm quinoline suspending agent of step (1) preparation again, shears, and adds percentage by weight at last and be 0.1～1% antiprecipitant, and shear-mixed is even, promptly gets the chlopyrifos thiacloprid suspending agent.
Compared with prior art, the present invention is by organophosphorus insecticide chlopyrifos and the composite a kind of agriculture chemical compounding agent that forms of chloro nicotinic insecticide thiophene worm quinoline and preparation method thereof, this composite dose have tag, stomach toxicity and systemic action, be mainly used in crop pests such as preventing and treating rice hoppers, rice leaf roller, striped rice borer and aphid.
