Embodiment 1

[0023] ②Preparation of film-forming agent

[0024] Add 500 grams of fresh pig blood into a 1-liter reaction pot, heat and boil with stirring for 1 hour to sterilize and sterilize to obtain blood gel. The obtained blood gel is transferred to a pulverizer for beating, and at the same time, 10-20 ml of 30% hydrogen peroxide solution is added to oxidize and decolorize to obtain a yellow blood coagulation product, which is blood solid, with a water content of 80%. Transfer the slurry product to a 1-liter reaction pot, add 500 ml of 2% chitosan acetic acid aqueous solution, 25 grams of allura red aluminum lake, adjust the pH to 5-6 with a little 0.5M NaOH, and mix well to obtain film-forming agent A.

Embodiment 2

[0027] ②Preparation of film-forming agent

[0028] The same method as in Example 1 was used to prepare a gelatinous blood solid. Transfer this gelatinous blood solid to a 1 liter reaction pot, add 5 ml epoxy methacrylate (reactive compound containing reactive epoxy groups), 10 ml methyl methacrylate and 0.5% Benzoyl peroxide was reacted under high-speed stirring at 50°C for 2 hours to obtain a blood solid derivative containing a reactive epoxy group with a semi-interpenetrating network structure, in which 500 milliliters of 2% chitosan acetic acid was added The aqueous solution and 50 grams of the temptation red aluminum lake are mixed evenly to form the film-forming agent B.

Embodiment 3

[0031] ②Preparation of film-forming agent

[0032] The same method as in Example 1 was used to prepare a gelatinous blood solid. Transfer this gelatinous blood solid to 1 liter of reaction pot, add 10 grams of sodium hydroxide, make it dissolve under stirring, measure the pH value greater than 10, gradually add dropwise 5ml epoxy methacrylate (containing polymerizable The active compound of ethylene double bond group), reacted for 2 hours under stirring, obtained the blood solid derivative containing polymerizable group, added 500 grams of 2% chitosan acetic acid aqueous solution, mixed and then added 5ml methacrylic acid Methyl ester, 5ml Tween 40, 50ml glycerin, 50g Allura red aluminum lake, stir well to form film-forming agent C.

Abstract

A filming agent as the coating of seed contains the filming substance consisting of animal blood and high-molecular filming component, auxiliary component and solvent. A seed-coating agent is prepared from said filming agent, agricultural active component and trigger. Its advantage is controlled release of rich nutrients.

Description

technical field [0001] The invention relates to a seed coating film-forming agent and a seed coating agent containing the film-forming agent. Background technique [0002] Seed coating agent is a compound preparation with film-forming properties used for coating crop seeds or other plant seeds. It is usually made of agricultural active ingredients (insecticides, fungicides, etc.), film-forming agents, dispersants, pigments or other additives, which can be directly or diluted and coated on the surface of seeds to form a certain strength and permeability. protective film. Among them, the film forming agent is the core of the seed coating agent product. Traditional seed coating film-forming agents are synthetic polymers and natural polymers, the former including polyvinyl acetate, polyethylene / vinyl acetate copolymer, polyvinyl alcohol or copolymers, polyacrylates, polyacrylates, etc.; The latter includes cellulose and its derivatives (such as cellulose acetate, hydroxypropy...
