PURPOSE: A manufacturing method for an amorphous conductive floor material is provided to prevent the conductivity of a floor material from becoming changed when the floor material is worn away. CONSTITUTION: A manufacturing method for an amorphous conductive floor material is as follows. A base sheet having two or more base colors and color patterns is extruded(200). The base sheet is cooled and crushed into mixed crushed chips(210). Fine powder is removed from the mixed crushed chips(220). The mixed and crushed chips are coated with liquefied conductive carbon black or conductive metal powder or composite powder(230). The crushed chips are thermally pressed through a press and are molded in a block(240). The molded block is sliced and is molded in a conductive sheet(250). |
