The invention discloses slip-resistant glaze, a preparation method thereof and a preparation method of a slip-resistant glaze brick. The slip-resistant glaze is prepared from, by mass, 40-60% of silica, 8-18% of sodium hydroxide, 10-20% of aluminum oxide, 1-3% of di-iron trioxide, 1-8% of calcium oxide, 1-5% of magnesium oxide, 3-8% of potassium oxide, 1-5% of sodium oxide, 2-8% of zinc oxide and5-15% of barium oxide. The preparation method of the slip-resistant glaze brick comprises the following steps that B001, the slip-resistant glaze is prepared; B002, a ceramic brick green body is prepared, and the surface of the ceramic brick green body is coated and printed with a glaze layer having a decorative effect; B003, the slip-resistant glaze in the step B001 is prepared into gloze slurry,the silk screen plate printing slip-resistant glaze slurry is applied to the surface of the ceramic brick green body in the step B002; B004, the ceramic brick body of step B003 is put into heat in akiln and is heated and burnt, edging is graded after cooling, and the slip-resistant glaze brick is obtained.
