Embodiment 1
[0043]
[0044] 1g of Nitrapyrin was heated past the melting point and melted into a liquid state, then 0.1g of styrene was added and stirred evenly to become the active ingredient mother liquor; 0.5g of emulsifier Tween-60 and aqueous solution were added to 50g of deionized water and stirred evenly to form an aqueous solution; Put the prepared mother liquor into the aqueous solution and turn on the high-speed homogenization to form a stable O / W emulsion; turn on the stirring (maintain 300 rpm), and then raise the temperature of the homogenized emulsion to 30°C to maintain the solidification of the stable capsule wall material After 5 hours of temperature, add 3g of NNO naphthalene sulfonate and 20g of magnesium aluminum silicate (2%) aqueous solution, add water to 100g and stir evenly to prepare 1% Nitrapyrin microcapsule sustained release agent.
Embodiment 2
[0046]
[0047] Heat 10g of Nitrapyrin over the melting point and melt into a liquid state, then add 2g of styrene monomer and stir evenly to the active ingredient mother liquor; add 2.0g of emulsifier fatty alcohol polyoxyethylene ether AEO-15 (Xingtai Bluestar) into 50g of Stir in deionized water to form an aqueous solution; put the prepared mother liquor into the aqueous solution and turn on high-speed homogenization to form a stable O / W emulsion; turn on stirring (maintain 450 rpm), and then raise the temperature of the homogenized emulsion to 70°C, maintain a stable solidification temperature of the capsule wall material for 7 hours, then add 4.0g of dispersant phosphate esters 601P, 15g of xanthan gum (2%) aqueous solution, add water to 100g and stir evenly to prepare 10% Nitrapyrin microcapsules slow release agent.
Embodiment 3
[0049]
[0050]
[0051] Heat 24g of Nitrapyrin over the melting point and melt into a liquid state, then add 6g of styrene and 2g of acrylate to stir evenly the active ingredient mother liquor; add 2.0g of emulsifier fatty alcohol polyoxyethylene ether AEO-9 (Nanjing Taihua) Add 40g of deionized water and stir to form an aqueous solution; put the prepared mother liquor into the aqueous solution and turn on high-speed homogenization to form a stable O / W emulsion; turn on stirring (maintain 400 rpm), and then put the homogenized The temperature of the emulsion is raised to 50°C, and the solidification temperature of the capsule wall material is maintained for 5 hours, then 5.0g of sodium lignosulfonate and 10g of xanthan gum (2%) aqueous solution are added as a dispersant, and the water is replenished to 100g and stirred evenly to obtain 24% Nitrapyrin microcapsule sustained release formulation.
