Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of suspending agent containing benzene emulsion and preparation method thereof.
Background technology
Chemical control is the important means that the mankind prevent and treat agricultural damage by disease and insect, chemical pesticide is to ensureing that the increasing both production and income of agricultural plays very important effect, but the use of agricultural chemicals, while Ensuring Food Safety is produced, also bring a series of environment and the social concerns such as residual, pollution.Therefore, the developing direction of pesticidal preparations industry is progressively to safe, environmental protection, water baseization development.Agricultural chemicals suspension agent refers to the preparation be scattered in the particulate homogenous of less than 4 microns by former for solid pesticide medicine in water, and be a kind of nonflammable explosive, particle diameter is little, and biologically active is high, and proportion is comparatively large, the environmental protection type agricultural chemical formulation that packaging volume is less.
Agricultural chemicals suspension agent has the following advantages compared with traditional pulvis: without dust harzard, to operator and Environmental security; Than great, packaging volume is little; Diffusibility number in water, directly can make spray liquid and use; There is the features such as particle is little, active surface is large, penetration is strong, cost is low.Therefore, suspending agent is other formulations of pesticide safety and environmental protections relatively, and suspending agent has become the larger pesticide species of water baseization pesticides new formulation tonnage.
Agricultural chemicals suspension agent has the following advantages compared with traditional liquor: take water as dispersion medium, and the inflammable and drug injury problem do not produced by organic solvent, alleviates the pollution to environment because of the use of agricultural chemicals.The existing forms of the pesticide active ingredient in suspending agent is generally the solid of particle diameter at 1-5 micron; Missible oil is transparent supernatant liquid, and in use active ingredient is generally molecular conformation.After being sprayed onto crop, the active ingredient of suspending agent is attached to crop surface with particle shape, and missible oil active ingredient is attached to crop surface with molecule and droplet form; Along with the evaporation of moisture, the adhesive ability of missible oil is better than the adhesive ability of suspending agent, so drug effect is also better than suspending agent; Also be as a same reason in resistance of rainwater washing against.So how improving suspending agent active ingredient is exactly the effective way promoting suspending agent drug effect at the adhesive ability of crop surface.
Benzene emulsion (styrene-acrylate emulsion) is obtained through emulsion copolymerization by styrene and acrylate monomer; Benzene emulsion adhesive force is good, and glued membrane is transparent, and water-fast, oil resistant, heat-resisting, ageing-resistant performance is good; Owing to introducing styrene segment in the copolymer, can improve the resistance to water of film, alkali tolerance, hardness, pollution resistance, and resistance to chalking, and overcome inflammable, explosive, poisonous, the shortcoming such as seriously polluted, cost is lower than pure-acrylic emulsion.
Because having excellent film forming and adhesion property, it mainly uses field to be at coating industry to current benzene emulsion, and also appears in the newspapers at end about the use of benzene emulsion in agricultural chemicals suspension agent.The present invention, aiming to provide the applications and preparation method of a kind of benzene emulsion in suspending agent, overcomes the shortcoming of this formulation.
