Plastic floorboard processing technology using digital printing

A method for processing plastic floorboards using digital printing, comprising:

• preparing a base material, wherein the base material comprises PVC, stone powder, a stabilizer, stearic acid, PE wax and a modifier;
• blending the base material at a temperature of 120° C. at a speed of 2000 r/min, and blending the base material at a speed of 200 r/min when the temperature falls to 50° C.;
• extruding the blended base material into a mold through a twin-screw extruder to form a stone-plastic base material;
• adjusting a gap between a surface embossing roll and a bottom embossing roll to enable the stone-plastic base material to pass through the gap, wherein the surface embossing roll has a first thickness and the bottom embossing roll has a second thickness, wherein a marking block is carved on an edge of the surface embossing roll;
• generating embossing patterns and positioning marks at equal intervals on a surface of the stone-plastic base material, wherein generating embossing patterns and positioning marks comprises passing the stone-plastic base material through the gap;
• cooling the stone-plastic base material at a natural temperature between 26° C.-30° C.;
• selecting a first positioning mark of the positioning marks as a first point and a second positioning mark of the positioning marks as a second point, wherein the second positioning mark is selected according to a required length of the plastic floorboard;
• cutting the stone-plastic base material into plastic floorboards with the required length, wherein cutting the stone-plastic base material comprises cutting the stone-plastic base material at the second point;
• using a digital printer to print the plastic floorboards, wherein the digital printer starts printing when the first point is sensed by a sensing device of the digital printer, and stops printing when the second point is sensed;
• shower-coating a UV primer paint and a UV finish paint on the plastic floorboards;
• reconditioning the plastic floorboards;
• and
• slotting the plastic floorboards.
