| titleOfInvention | Preparation method for foaming type nutrient composite water-retaining agent |
| abstract | The invention provides a preparation method for a foaming type nutrient composite water-retaining agent and belongs to the field of composite materials. Plant ash, acrylamide and palygorskite clay rude ore are adopted as raw materials, potassium persulfate is adopted as an initiating agent, N,N'-methylene-bisacrylamide and the like are adopted as cross-linking agents, ammonium bicarbonate is adopted as a foaming agent, the copolymerization of an aqueous solution is initiated through a free radical to obtain the composite water-retaining agent which has the effects of high water absorption velocity, large water absorption capacity, long water retaining time, good salinity tolerance and high gel strength. Through the addition of the natural fertilizer plant ash, the water-retaining agent is endowed with the advantage of being rich in nutrient elements, thereby being more suitable for the fields of crop planting and desertification environment remediation. The palygorskite clay rude ore is adopted as the main raw material, the addition of inorganic substances is high, so as to greatly reduce the cost of the water-retaining agent; besides, the preparation technology of the composite water-retaining agent is simple, the operation is convenient, and industrialization is facilitated. |
