Abstract
A method of preparing hydrotalcite for a PVC stabilizer, which comprises: forming crystals of hydrotalcite represented by a formula of M(II)XM(III)Y(OH)N(Am—)Z. nH2O, wherein M(II) is a divalent metal selected from Mg2+, Ni2+ and Zn2+; M(III) is a trivalent metal selected from Al3+, Fe3+, Cr3+ and Co3+; and Am— is an anion selected from CO32-, OH—, NO3-, SO42- and halides; and depositing zinc (Zn) onto the hydrotalcite by using any one method of electrode-position, chloride ion deposition, and plasma deposition to provide zinc-deposited hydrotalcite.
