Description
Technical Field

Background
Compared with common calcium carbonate, the nano calcium carbonate has more functions and wider application. Because the particle size of the nano calcium carbonate particles is very small, the number of atoms on the surface is very large, the surface free energy is large, and the particles are in a non-thermodynamic stable state and are easy to agglomerate and adhere, thereby losing the original surface property; on the other hand, the nano calcium carbonate is an inorganic material, and the surface of the particle is hydrophilic and oleophobic, so that the bonding force with a polymer interface is weak, and the application of the nano calcium carbonate in an oily material is greatly limited. These disadvantages become more apparent as the field of application of nano calcium carbonate is continuously expanded. In order to fully exert the advantages of the nano calcium carbonate and improve the performance of the nano calcium carbonate, different surface modification methods and effective modification processes are required to be adopted for surface modification.
At present, the modification method of nano calcium carbonate mainly comprises a dry method surface modification process and a wet method surface modification process, and because the nano calcium carbonate has large specific surface area and strong surface electrostatic action and is easy to agglomerate to form larger secondary particles in the processes of dehydration and drying, the surface modification of the nano calcium carbonate by the dry method surface modification process is difficult to be uniform.
Compared with the traditional dry surface modification mode, the wet modified nano calcium carbonate has large contact area with the surface modifier, more uniform surface coating and high modification efficiency because the calcium carbonate is more easily dispersed in a liquid phase. In the wet surface chemical coating modification process, the main process parameters are temperature, slurry concentration, reaction time, drying temperature, drying time and the like, and the control of the wet modification temperature is particularly important because the decomposition temperature of the organic surface modifier is generally low and the excessive temperature can cause the damage or the failure of the surface modifier.
