| titleOfInvention | Green preparation method of micro-nano cellulose |
| abstract | The invention discloses a green preparation method of micro-nano cellulose. The method comprises the steps of firstly dipping fiber raw materials in suspension liquid of calcium hydroxide, then dissociating the dipping slurry by a mechanical method, then adding a crystal form control agent into the slurry suspension liquid after dissociation (or before dissociation), uniformly mixing, then stirring the suspension liquid at a certain temperature while introducing gas containing carbon dioxide until the pH value of the suspension liquid reaches a certain value and then reaching a carbonization end point, and finally obtaining the calcium carbonate coated micro-nano cellulose. The method has the advantages of strong raw material applicability, mild pretreatment conditions, low requirements on equipment, low price and high utilization rate of medicines, simple process, no need of washing materials after pretreatment, no generation of any waste liquid and washing wastewater, environmental friendliness, less energy consumption of mechanical dissociation after pretreatment, low cost and contribution to industrial production. The calcium carbonate coated micro-nano cellulose obtained by the invention has controllable calcium carbonate form and can meet the application requirements of different fields. |
