Abstract

The present invention relates to a leakage-preventing high performance desiccant composition and a preparation method therefor, wherein a solid desiccant composition includes calcium chloride (CaCl 2 ), magnesium chloride (MgCl 2 ), and metal oxide, wherein the metal oxide may be calcium oxide (CaO), and a gel desiccant composition includes metal chloride and an absorbent polymer, wherein the metal chloride may be calcium chloride (CaCl 2 ) and magnesium chloride (MgCl 2 ), and the absorbent polymer may be CMC (carboxymethyl cellulose).

Claims (6)

1 . A solid desiccant composition comprising:

calcium chloride (CaCl 2 );

magnesium chloride (MgCl 2 ); and

metal oxide, wherein,

a mass ratio of the calcium chloride and the magnesium chloride is 1:9, and

a mass ratio of a sum of the calcium chloride and the magnesium chloride, and the metal oxide is 1:0.5 to 1:2.
