MG-TI-AL COMPOSITE METAL HYDROXIDE HAVING A LAMINATED STRUCTURE, AND A PRODUCTION METHOD THEREFOR

摘要

The present invention relates to a novel Mg-Ti-Al composite metal hydroxide of chemical formula 1 below and to production method therefor. Mg-Ti-Al composite hydroxide particles can be obtained by subjecting a solution containing a magnesium salt and a titanium salt to ultrasound processing and carrying out a high-temperature and high-pressure reaction with a solution containing an aluminum salt in the proportions of the metal elements comprised in the Mg-Ti-Al composite metal hydroxide of chemical formula 1 below, thereby giving the advantageous effects that the halogen capturing ability is excellent and, when used in a polymer, degradation and earily-staining prevention properties and transparency are outstanding. In the above formula, A 1 n- and A 2 m- are respectively anions having valences of n and m, a/c is from 1 to 5, and b, c, d and x are numbers satisfying the conditions of 0 < b ‰¤ 5, 0 < c ‰¤ 5, 0 < d and 0 ‰¤ x < 5, while e and f are numbers satisfying the condition of 1 ‰¤ ne + mf ‰¤ 5.
