The invention discloses a high-performance aluminosilicate glass primarily made from red mud and a preparation method of the high-performance aluminosilicate glass and belongs to the crossing field of waste disposal and inorganic metal materials. Red mud, namely the waste from industrial production of Al2O3, causes water pollution, soil alkalinization and high land occupation and the like. Since red mud is added into industrial raw materials, red mud is utilized effectively, harms to production and life are reduced; and further, on the basis of advantages of content such as Fe2O3, Na2O, K2O and the like of the red mud, performance of aluminosilicate glass can be improved, and particularly, chemical stability of the aluminosilicate glass is much superior to that of conventional E-glass, AR-glass and the like. The aluminosilicate glass is prepared from, by weight, 14.2-27.4% of Bayer-process red mud, 11.9-17.5% of dolomite, 26.3-47.6% of pyrophyllite, 23.8-26.3% of quartz powder and 2-2.5% of fluorite. As all of raw materials of the aluminosilicate glass, except for the red mud, are of industrial grade, the aluminosilicate glass can be applied to industrial production well.
