摘要
Abstract
The surface modified nano-sized Mg (OH)2 was prepared by direct precipitation method with magnesium nitrate and sodium hydroxied as raw materials and phosphate ester as modifying agent. Through experiments with measurement of sediment volume of the reaction product, the suitable dosage of phosphate ester is identified as 1.0% (w). Both samples of reaction product with and without phosphate ester modification were characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and transmission electron microscope (TEM). The results indicated that phosphate ester is adsorbed onto the surface of nano-sized Mg (OH)2, changing the surface characteristics and improving the dispersion of the Mg(OH)2 particles in organic medium. Compared to the unmodified Mg (OH)2 particles, the main XRD diffraction peak of the phosphate ester modified nano-sized Mg(OH)2 particles is strengthened, showing lower degree of agglomeration and lower bulk density of the modified product.关键词
