Hydrophobic nano calcium carbonate with anti-thixotropy, and preparation method thereof
The invention relates to hydrophobic nano calcium carbonate with anti-thixotropy, and a preparation method thereof. The particle size of the hydrophobic nano calcium carbonate is 100-250 nm, the polydispersity index is 0.197-0.645, the Zeta potential is 3-11 mV, and the thixotropic ring area is -60000 to 100000 Pa.S. The hydrophobic nano calcium carbonate is obtained by modifying nano calcium carbonate with isostearic acid and hexadecyl trimethyl ammonium bromide. The nano calcium carbonate provided by the invention has excellent negative thixotropy, hydrophobicity, lipophilicity and dispersity, is wide in application and has good economic benefits.
本发明涉及一种具有反触变性的疏水纳米碳酸钙及其制备方法，所述疏水纳米碳酸钙粒径为100～250nm，多分散性指数为0.197～0.645，Zeta电位为3～11mV，触变环面积为‑60000～‑100000Pa·s。所述疏水纳米碳酸钙由异硬脂酸和十六烷基三甲基溴化铵对纳米碳酸钙改性得到。本发明提供的纳米碳酸钙具有优异的负触变性、疏水亲油性及分散性，用途广泛，具有良好的经济效益。
