Microporous light-weight washing water pumice stone and preparation method thereof

The invention relates to microporous light-weight washing water pumice and a preparation method thereof.The microporous light-weight washing water pumice is prepared from potassium-sodium feldspar, magnesian clay, wollastonite powder, aluminum oxide, burnout organic matter, a foaming agent, silicon carbide powder, limestone powder, carbon clay, boric acid and calcium oxide. The preparation method of the microporous light-weight washing water pumice comprises the following steps of 1, preparing silicon carbide powder; 2, preparing a foaming agent; 3, preparing wollastonite powder; 4, preparing a first mixture; 5, preparing a second mixture; 6, forming in a forming stamping die; and 7, preparing the microporous light-weight washing water pumice with the weight of 5-15 g and the micropore diameter of 0.01-0.03 mm. The ratio of the use amount of the microporous light-weight washing water pumice to the natural volcanic pumice is 1:9, so that the use amount is greatly reduced, the production cost is saved, jean tex
