| titleOfInvention | Acrylic acid water-retaining layer of coated fertilizer and preparation method and device thereof |
| abstract | The invention relates to an acrylic acid water retention layer of a coated fertilizer, which comprises 40-80 parts of acrylic acid, 10-80 parts of acrylamide, 10-60 parts of potassium hydroxide, 0.005-4 parts of N, N' -methylene bisacrylamide, 0.005-4 parts of potassium persulfate and 50-160 parts of deionized water. The invention also relates to a preparation method of the water-retaining layer, which comprises the steps of preparing the pre-polymerization liquid and the coating liquid and forming the water-retaining layer. The invention also relates to a device for preparing the water-retaining layer, which adopts automatic mechanical transmission to mix the raw materials and then transfer the raw materials into the fluidized bed, and the water-retaining layer has uniform thickness; the coating process has no dust, toxic gas and liquid and potential environmental pollution, and the coating liquid can not be polymerized into gel before being sprayed on the surface of the granular fertilizer. |
