SYNTHETIC SMECTITE PASTE, SYNTHETIC SMECTITE SELF-SUPPORTING FILM, SYNTHETIC SMECTITE FILM, AND METHOD FOR PRODUCING SYNTHETIC SMECTITE FILM

摘要

PROBLEM TO BE SOLVED: To provide a synthetic smectite paste which has enough film formability and makes the formation of a smectite film excellent in flexibility and water resistance possible, a synthetic smectite self-supporting film using the paste, the synthetic smectite film, and a method for producing the synthetic smectite film.;SOLUTION: The synthetic smectite paste includes the three octahedron type synthetic smectite having a sodium ion content of 10 ppm or below and a water-soluble polymer having a sodium ion content of 10 ppm or below. The mass ratio between the three octahedron type synthetic smectite and the water-soluble polymer is 95/5-50/50.;COPYRIGHT: (C)2012,JPO&INPIT
