| titleOfInvention | A kind of dispersant, its preparation method and the application in nano-calcium carbonate disperses thereof |
| abstract | The invention provides a kind of dispersant, its preparation method and the application in nano-calcium carbonate disperses thereof, described dispersant is polymer and heteropoly acid solution to be mixed by the concentration ratio of 1:1, at room temperature magnetic agitation 24～48 hours, it is that 3000～3800 daltonian dialyzers are dialysed 24～48 hours with molecular cut off, be 1Pa in vacuum, temperature be 65 DEG C to 55 DEG C under conditions of on freezer dryer the organic-inorganic hybrid material of gained after lyophilizing.During disperseing nano-calcium carbonate in aqueous medium, introduce hydrophilic organic-inorganic hybrid material parcel absorption nano-calcium carbonate, and then be effectively improved nano-calcium carbonate dispersibility in aqueous solvent.This organic-inorganic hybrid material is easily prepared, and dispersive process is also easy to operation, and the average diameter of the nano-calcium carbonate particle diameter in the nano-calcium carbonate dispersion liquid of gained can reach below 100 nanometers. |
