Problems solved by technology

However, the residual monomers and additives in most synthetic polymer materials, such as anionic monomer acrylic acid, urea-formaldehyde resin, and formaldehyde in polyvinyl formal have varying degrees of impact on seeds and seedlings
Therefore, resins produced from formaldehyde and synthetic polymers using anionic monomer acrylic acid as hydrophilic monomers are potentially risky when used as seed coatings and film-forming agents.

preparation example Construction

[0030] (1) Preparation of film-forming agent

[0031] (1) Preparation of BA / VAC / AMPS terpolymer film-forming agent by emulsion polymerization

[0032] Component 1: BA19.2g, VAC19.2g

[0033] Component 2: AMPS 1.6g, dissolved in 12g water

[0034] Component 3: The amount of initiator KPS is 1% of the monomer, dissolved in 9g of water

[0035] Component four: DNS-1035, sodium lauryl sulfate (K12), DNS-1035: K12 = 3: 1, 6% of the total monomer weight, DNS-1035: K12 = 1.8g: 0.6g

[0036] Component 5: Methylidene is dissolved in water to make a 0.5% solution

[0037] Preparation:

[0038] Mix 2 / 3 of component 1 with 2 / 3 of component 2, add component 4, emulsify with 3g of component 5, and emulsify with a high-speed shear emulsifier for 10 minutes, transfer the emulsion into a dropping funnel with a stirring paddle, In the three-necked flask of the reflux condenser, the water bath is 80°C, and start to add 2 / 3 of the initiator solution dropwise. When there is blue fluorescence ...

preparation example

[0047] (1) 10% polyketone suspension seed coating

[0048] Component 1: 6% to 10% of this film former

[0049] Component two: 12.5% ​​carbendazim, 2.5% triadimefon.

[0050] Component 3: Dissolve emulsifier and stabilizer in water to make an aqueous solution, add titanium dioxide, pearl powder, and color paste.

[0051] Mix components 2 and 3, stir well, add component 1, stir evenly, and sand mill for 40 minutes.

[0052] Applicable crops: cotton, wheat

[0053] Control objects: cotton blight and red rot, prevent rotten seeds, and can greatly reduce the incidence and disease index of cotton seedling diseases, increase germination rate, reduce rotten seed rate and dead seedling rate. The coated seeds can be stored safely for a long time, showing an obvious trend of increasing germination rate. In the case of poor seed maturity, increase the hard seed rate, correspondingly reduce field rotten seeds and dead seedlings; long-lasting effect; wheat stripe rust, powdery mildew. ...

Abstract

The present invention discloses a film-builder used for seed-coating agent, which is a copolymer produced by initiation and co-polymerization of AMPS monomer and at least one vinyl monomer. In the co-polymer, mole percentage of AMPS monomer is from 0.5% to 30%, and the balance is vinyl monomer, wherein the vinyl monomer is chosen from acrylic ester or metacrylic acid ester or vinyl acetate or phenyl ethylene or acrylic amide. The film-builder has good film building and sustained-release function, high film building strength, water adsorb and resistance, and chemical stability, and favorable biocompatibility with agronomic crop. The shedding rate of seed lagging cover after drying low, film after absorbing water and expansion ventilated and not dissolvable, active ingredient can be released slowly, and favorable growing microenvironment for plant especially crops can be produced.

Description

1. Technical field [0001] The invention relates to an auxiliary agent for agricultural chemicals, in particular to a film-forming agent for seed coating agents. 2. Background technology [0002] Seed coating technology is a new agricultural production technology that has been highly praised by agricultural experts in my country and generally welcomed by farmers in recent years, and has achieved good results in production practice. Seed coating technology is a new technology for seed treatment that is widely used in the world developed on the basis of traditional seed soaking and seed dressing. The organic combination of comprehensive management of field diseases, insects and pests at the seedling stage. Improved seed coating technology is an important means to build high-yield, high-quality, high-efficiency modern agriculture and sustainable agricultural development. The seed coating of commercial seeds is one of the important technical measures to improve the level of agri...
