Water softening filtering material and preparation method thereof

The invention discloses a water softening filtering material and a preparation method thereof. In the preparation process, ceramic beads serve as carriers, the effective component magnesium acrylate is uniformed wrapped on the surfaces of the ceramic beads through stirring, heating and concentrating to perform polymerization to form the water softening filtering material; when the filtering material is used for performing water softening reaction, the magnesium acrylate catalyzes dehydrogenation of calcium bicarbonate and magnesium bicarbonate in water to convert into a carbonate nanoscale crystal through nuclear assisted crystallization, and the carbonate nanoscale crystal is suspended in water, so that hard water is softened. The nano-crystal has electric neutrality, strong bonding of chemical bonds on the surface is avoided, limescale is not formed again, the water after the reaction is softened completely, calcium salt and magnesium salt are not attached to the used filtering material, regeneration reacti
