Embodiment 1

[0071] In a stirring four-neck flask, add 0.5 parts of vinyltrimethoxysilane, 5 parts of octamethylcyclotetrasiloxane, 1.5 parts of 99% acrylamide, 1 part of acrylic acid, 0.1 parts of ammonium persulfate, 5 parts of butyl acrylate, 1 part of acrylonitrile, 0.2 part of sodium dodecylbenzenesulfonate, 0.1 part of N, N, N', N'-tetramethylethylenediamine, 750 parts of deionized water, After raw materials, stir rapidly for 30 minutes, then heat to 75°C--80°C, keep warm for 2 hours, add polyvinyl alcohol solution containing 22.1 parts of polyvinyl alcohol and 100 parts of deionized water to the reaction system, control the temperature at 80°C--82°C, continue stirring and reacting for 1 hour after adding, stop heating, cool to room temperature, adjust pH value with ammonia water, stir evenly and discharge. A viscous transparent liquid was obtained with a pH value of 6.8, a viscosity of 2200 mPaS at room temperature, a viscosity-average molecular weight of 800,000, m≈2000, n≈1060.

Embodiment 2

[0073]In a stirring four-neck flask, add 0.5 parts of vinyltrimethoxysilane, 5 parts of octamethylcyclotetrasiloxane, 1.3 parts of 99% acrylamide, 1 part of acrylic acid, 0.2 parts of ammonium persulfate, 5 parts of butyl acrylate, 1 part of methyl methacrylate, 0.1 part of sodium dodecylbenzenesulfonate, 0.1 part of N, N, N', N'-tetramethylethylenediamine, 125 parts of deionized water, After adding all the raw materials, stir rapidly for 30 minutes, then heat to 75°C--80°C, keep warm for 2 hours, add polyvinyl acetate containing 22.3 parts of polyvinyl acetate and 100 parts of deionized water to the reaction system The temperature of the solution is controlled at 80°C--82°C. After the addition, continue to stir and react for 1 hour, stop heating, cool to room temperature, adjust the pH value with ammonia water, stir evenly and discharge. A viscous transparent liquid was obtained with a pH value of 6.8, a viscosity of 1900 mPaS at room temperature, a viscosity-average molecula...

Abstract

The invention discloses an application of an organic silicone modified high-molecular compound as a seed coating film former. The organic silicone modified high-molecular compound has a molecular structure fragment described in a general formula (I): definitions of all groups in the formula are described in the instruction. The film former with a reticular structure is formed by the crosslinking reaction of the molecular structure fragment in the general formula (1) and a soluble film forming material containing hydroxyl, amino, carboxyl, alkoxy and amide groups. The film former has good water resistance and water permeability, and can simultaneously meet the different requirements of a dry field and a paddy field. A seed coating agent prepared by adopting the film forming material meets the requirements on both viscosity and strength, has significant improvement on expulsion rate, viscosity and liquidity, and simultaneously has relatively high brightness and vividness.

Description

technical field [0001] The invention belongs to the fields of macromolecule chemistry and agricultural seed coating agents, and relates to an application of an organosilicon-modified macromolecular compound as a film-forming agent for seed coating. Background technique [0002] The film-forming agent for seed coating (referred to as film-forming agent) is a substance that can adhere active components such as pesticides, micro-fertilizers, growth regulators and slow-release agents in the seed coating agent to the surface of the seed and solidify to form a film. [0003] Generally, different seed coating formulations contain different components, which generally include active components and inactive components. Among them, the active components mainly include insecticides, fungicides, plant growth regulators, fertilizers and beneficial microorganisms, etc., which are active ingredients that directly play a role in the seed coating agent, and their type, composition and conten...
