Problems solved by technology

Since the aqueous suspoemulsion is a three-phase mixture, and has both dynamic and thermodynamic instability, it is prone to problems such as pH value or viscosity cannot be kept constant, particle size increases, etc.
Also in some of the surfactants used in known suspoemulsions, such as alkylphenol ethoxylates, which are not entirely satisfactory in terms of ecology and toxicity, alternatives are therefore required

preparation example Construction

[0023] The preparation method of atrazine into a suspension agent is: adding the weighed original drug atrazine, dispersant, antifreeze, thickener, preservative, and water into a shearing kettle to disperse evenly, and then enter a sand mill. Grind to the required particle size (the average particle size is less than 3 microns), and finally add the defoamer and stir evenly.

[0024] Preparation of suspoemulsion: the present invention adds oil phase, atrazine suspending agent, stabilizer, preservative, defoamer and water to the shearing kettle for uniform dispersion, and the shearing time is 5-10 minutes (rotation speed is 2950rmp), namely A suspoemulsion is obtained, and the average particle size is controlled to be less than 3 microns.

Abstract

The invention relates to a suspension emulsion containing atrazine and a chloroacetamide pesticide, which comprises the following components in percentage by weight: 15-30% of atrazine, 10-35% of pesticide B, 0-50% of a cosolvent, 1-15% of an emulsifier, 0.1-6% of a dispersing agent, 1-10% of an antifreeze agent, 0-5% of a thickening agent, 0.1-2% of an antifoaming agent, 0.1-3% of a corrosion remover, 0.01-5% of a stabilizer and the balance of water, wherein the emulsifier is fatty alcohol polyoxyethylene polyoxypropylene ether and a derivative of the fatty alcohol polyoxyethylene polyoxypropylene ether, and the pesticide B is a chloroacetamide weed killer. The suspension emulsion has the following advantages: 1, stability is realized, and the problems that the pH value or the viscosity is not constant, and the particle size is increased are not easy to appear; 2, the components are more environmentally-friendly and safer.

Description

technical field [0001] The invention relates to a herbicidal and pesticide composition, in particular to a suspoemulsion containing atrazine and chloroacetamide pesticides. Background technique [0002] Aqueous suspoemulsion is one or several water-insoluble pesticide liquid active ingredients (or a mixture of low-melting pesticide active ingredients in a solvent) and another one or several water-insoluble pesticide solid active ingredients, using water as a medium and relying on The surfactant is processed into a stable suspoemulsion dispersion liquid formulation. It has the advantages of suspending agent and water emulsion, such as avoiding the pollution and poisoning of pesticide emulsifiable concentrate and wettable powder to the environment and operators due to organic solvents and dust, safe storage and transportation, and high biological activity. Since the aqueous suspoemulsion is a three-phase mixture with both kinetic and thermodynamic instability, it is prone to ...
