Claim:
A glue-free anti-slip polyvinyl chloride floor brick, characterized in that the polyvinyl chloride floor brick comprises a polyvinyl chloride anti-slip layer, a polyvinyl chloride bottom material layer, a polyvinyl chloride middle material layer, a polyvinyl chloride printed layer and a polyvinyl chloride wear-resistant layer which are bottom-up sequentially stacked and combined by thermal pressing, the polyvinyl chloride anti-slip layer includes a bottom surface utilized to contact a ground surface and formed with a flexible thermal-pressed pattern by thermal pressing, the thermal-pressed pattern includes a plurality of continuously and repetitively connected, closed and non-equilateral hexagonal protruded ribs circumferentially formed as a closed concave-chambered sucking disk, wherein: a material ingredient of the polyvinyl chloride anti-slip layer measured by weight includes degree of polymerization of 1000 of polyvinyl chloride from 58.5% to 63.5%, plasticizer from 34.9% to 39%, stabilizer from 0.95% to 2.1%, color powder from 0.5% to 0.69% and 800 mesh calcium carbonate from 0.06% to 0.08%, which are amounted to 100%; and the non-equilateral hexagonal protruded rib has a shape circumferentially formed by two isometric and parallel positive short sides and two pairs of two parallel slanted long sides wherein the length of each positive short side is ranged from 4 mm to 8 mm, the length of each slanted long side is ranged from 5 mm to 9 mm, the length of the slanted long side is absolutely greater than that of the positive short side, and the positive short side and the slanted long side have same width of 1 mm and same height ranged from 0.25 mm to 0.35 mm.
