DISINTEGRATOR AND DISINTEGRABLE MOLDED PRODUCT CONTAINING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a disintegrator that shortens an disintegration time of a molded product and has disintegration effect to increase water dispersibility and shaping effect not to impair strength of a molded product even in high content of the disintegrator.

SOLUTION: The disintegrator comprises a hydrotalcite compound represented by formula (1) (M2+)1-x(M3+)x(OH)2(SO4)0.5x-mH2O (1) (M2+is a divalent metal ion; M3+is a trivalent metal ion; An-is an n-valent anion; x and m satisfy conditions of 0COPYRIGHT: (C)2006,JPO&NCIPI
