specific Embodiment approach 1

[0016] Specific embodiment one: the film-forming agent of a kind of suspension seed coating agent of this embodiment, is made up of material A, 100-200 parts of polyvinyl alcohol, 10-30 parts of chlorpyrifos, 180~210 parts of styrene , 180-210 parts of butyl acrylate, 20-30 parts of methyl methacrylate, 20-30 parts of methacrylic acid, 1-3 parts of sodium bicarbonate, 7-9 parts of sodium acrylamido isopropyl sulfonate, 9 ~11 parts of alkyl alcohol polyoxyethylene (3) ammonium sulfate, 25~35 parts of sodium dodecylbenzenesulfonate, 5~7 parts of potassium persulfate, 1~3 parts of N,N'-methylene propylene Amide and 780-810 parts of deionized water; wherein substance A is 20-80 parts of chitosan, 5-25 parts of sodium alginate or 2-10 parts of sodium carboxymethyl cellulose.

[0017] The film-forming agent of this embodiment has water-insoluble properties, the coating film will not be dissolved when soaking seeds, the film-forming time is short, the coating shedding rate is low, an...

specific Embodiment approach 2

[0018] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the film-forming agent of suspension seed coating agent is made of 48 parts of chitosan, 180 parts of polyvinyl alcohol, 12 parts of chlorpyridin, 200 parts by mass. Parts of styrene, 200 parts of butyl acrylate, 25 parts of methyl methacrylate, 25 parts of methacrylic acid, 2 parts of sodium bicarbonate, 8 parts of sodium acrylamidoisopropyl sulfonate, 10 parts of alkyl alcohol polyoxyethylene (3) Made of ammonium sulfate, 30 parts of sodium dodecylbenzenesulfonate, 6 parts of potassium persulfate, 1 part of N,N'-methylene acrylamide and 800 parts of deionized water. Others are the same as the first embodiment.

specific Embodiment approach 3

[0019] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that the film-forming agent of the suspended seed coating is composed of 14 parts of sodium alginate, 180 parts of polyvinyl alcohol, and 12 parts of chlorpyridin in parts by mass. , 200 parts of styrene, 200 parts of butyl acrylate, 25 parts of methyl methacrylate, 25 parts of methacrylic acid, 2 parts of sodium bicarbonate, 8 parts of sodium acrylamido isopropyl sulfonate, 10 parts of polyalkylene alcohol Made from oxyethylene(3) ammonium sulfate, 30 parts sodium dodecylbenzenesulfonate, 6 parts potassium persulfate, 1 part N,N'-methylene acrylamide, and 800 parts deionized water. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention relates to a film-forming agent of a flowable seed coating formulation and a preparation method thereof. The film-forming agent of the flowable seed coating formulation is prepared from susbtance A, polyvinyl alcohol, fenclorin, styrene, butyl acrylate, methyl methacrylate, methacrylic acid, sodium bicarbonate, acrylamide isopropyl sodium sulfonate, alkyl alcohol polyoxyethylene (3) ammonium sulfate, sodium dodecyl benzene sulfonate, potassium persulfate, N, N'-methylene acrylamide and deionized water. The preparation method includes: 1. weighing raw materials; 2. preparing an A-PVA-F blended solution; and 3. preparing the film-forming agent, thus completing preparation of the film-forming agent of the flowable seed coating formulation. The film-forming agent provided in the invention has water insolubility, a coating film cannot be dissolved when it is used for soaking seeds, the film-forming time is short, and the coating has low shedding rate and good air permeability. With good compatibility with the formula of the pesticide flowable seed coating formulation, the film-forming agent is safe to crops and does not influence seed germination. The film-forming agent can be applicable to the pesticide field.

Description

technical field [0001] The invention relates to a film-forming agent for a suspended seed coating agent and a preparation method thereof. Background technique [0002] Seed Coating formulation is a special type of pesticide formulation gradually formed with the development of crop seed coating technology. It is a pesticide formulation with film-forming properties for the treatment of crops or other plant seeds. The principle is to tightly coat the active ingredients of pesticides on the surface of seeds to prevent and control seed-borne, soil-borne, seedling pests and diseases that systematically infect adult plants. At present, the formulations used for pesticide seed coatings include suspension seed coating (FS), powder (DP) seed coating, ultrafine powder (UP) seed coating, microemulsion (ME) seed coating, water emulsion (EW) ) Seed coating agent, etc. Among them, the suspension seed coating (FS) preparation is easy to process, has good seed coating effect, and is suita...
