Abstract

The invention relates to the field of a waterproof material, in particular to a waterproof microbead and a preparation method thereof. The waterproof microbead is prepared through the processes of mixing stirring, heating granulation, cooling and sieving of the following raw materials in percentage by mass: 90 to 96 percent of fine tailing, 2 to 6 percent of paraffin, 1 to 3 percent of bentonite,0.3 to 0.6 percent of calcium oxide and 0.7 to 0.9 percent of nanometer aluminum oxide powder. Through the synergistic effects among various raw materials, the prepared waterproof microbead has the advantages of high intensity and waterproof and anti-crack functions; the soil water seepage performance and the soil air permeablity performance can be improved; the soil can be effectively improved and the plant growth is facilitated.
