Abstract

The invention discloses a high-activity nano-calcium carbonate which comprises the following components by mass: 90-96% nano calcium carbonate base material, 0.25-0.5% of coconut oil or palm oil, 1.35-2.5% of soap grains, 2-5% of a fatty acid salt surfactant, 0.4-2% of a nonionic surfactant. The high-activity nano-calcium carbonate has high particle dispersion and lipophilicity, has the activation rate much higher than that of the ordinary activated calcium carbonate and the oil absorption value lower than that of the ordinary activated calcium carbonate, and is nano-calcium carbonate with relatively good activity; the activated nano-calcium carbonate product can avoid the agglomeration of nano-calcium carbonate particles, can reduce the particles to the most primitive state, and can more clearly show characteristics of functional materials when being applied to different high polymers.

Description

technical field [0001] The invention relates to the technical field of nano-calcium carbonate, in particular to a highly active nano-calcium carbonate treated with surface activity. Background technique [0002] At present, due to the small particle size of nano-calcium carbonate, it has a large specific surface area and high specific surface energy, and it is easy to agglomerate the particles to increase the particle size, which will affect the functions of the nanoparticles when they are finally used. At the same time, calcium carbonate has a certain degree of basicity and polarity, and has poor affinity with organic polymers, and is unevenly dispersed in the polymer matrix, resulting in a decrease in the mechanical properties of the material. The surface modification effect is very important for the application of nano-calcium carbonate. The surface modification methods of calcium carbonate can be divided into dry surface treatment and wet surface treatment. The dry met...
