A composition of matter, including a phlogopite powder or muscovite powder, clinoptilolite or mordenite, and kaolinite. The composition of matter is prepared as follows: 1) mixing the phlogopite powder or muscovite powder, the clinoptilolite or mordenite, and the kaolinite in a weight ratio of 50-70:0-30:0-50; adding a solution including isopropanol and n-butanol to a mixture of the phlogopite powder or muscovite powder, the clinoptilolite or mordenite, and the kaolinite, thereby yielding a mixed solution; 2) adding a silane coupling agent to the mixed solution, and continuously magnetically stirring the mixed solution for 30 min; adding distilled water to the mixed solution, and continuously magnetically stirring for 30 min; and adding methyl silicone oil to the mixed solution, and magnetically stirring for an hour, thereby yielding a slurry; and 3) drying the slurry at a temperature of 150-200° C.
