Water softening material and preparation method thereof

The invention relates to the technical field of power plant water treatment, in particular to a water softening material and a preparation method thereof, and the water softening material comprises natural bamboo fibers, chitosan, sodium alginate and sodium humate. Wherein the surface of the natural bamboo fiber contains a large number of hydroxyl groups, the surface of the sodium alginate contains a large number of carboxyl groups and hydroxyl groups, and the surface of the chitosan contains a large number of carboxyl groups, hydroxyl groups, phenolic hydroxyl groups and amino groups, so that the sodium alginate and the natural bamboo fiber can be subjected to esterification reaction to convert the hydroxyl groups on the surface of the natural bamboo fiber into ester groups; the sodium humate can be adsorbed and combined with amino ions on the surface of the chitosan, and meanwhile, ester groups on the surface of the natural bamboo fiber and the chitosan are subjected to amidation reaction, so that the natur
