| titleOfInvention | A kind of humic acid-based composite water-retaining agent and preparation method thereof |
| abstract | The invention belongs to the technical field of water-absorbing resins, relates to a humic acid-based composite water-retaining agent, and solves the technical problems of high cost, poor salt tolerance and water-retention performance of the existing agricultural water-retaining agent. The special feature of the humic acid-based composite water-retaining agent is that the proportion of raw materials by weight is: 1 to 5 parts of potassium humate, 20 parts of acrylic acid, 8 to 14 parts of potassium hydroxide, 2-acrylamide-2 -1 to 5 parts of methylpropanesulfonic acid, 100 to 160 parts of cyclohexane, 1 to 2 parts of dispersant, 0.1 to 0.5 parts of initiator, 0.008 to 0.05 parts of water-soluble crosslinking agent, oil-soluble crosslinking agent 0.008 to 0.04 part of the coupling agent, 0.02 to 0.1 part of the coupling agent, 0.2 to 5 parts of bentonite, and 0.2 to 5 parts of kaolin. The present invention also provides a preparation method for preparing the above-mentioned humic acid-based composite water-retaining agent. |
