Abstract

The invention relates to a synthetic resin tile, specifically to an easily-degradable synthetic resin tile and a preparation method thereof. The easily-degradable synthetic resin tile comprises a PVC layer, a PLA layer and an ASA layer which are successively arranged from the inside to the outside, wherein the PVC layer comprises PVC powder, heavyweight calcium carbonate, wood charcoal powder, PLA powder, a stabilizer, a lubricant, a processing auxiliary agent and a toughening agent; the PLA layer comprises PLA powder; and the ASA layer comprises PLA powder, ASA and bamboo-wood powder. The preparation method comprises the following steps: heating the PVC powder, the wood charcoal powder and the PLA powder under stirring to 60 DEG C, adding the stabilizer, the toughening agent and the processing auxiliary agent, carrying out heating under stirring to 90 DEG C, then adding a filling agent and the lubricant, continuing heating under stirring to 120 DEG C, carrying out cooling to 45 DEG C, carrying out extrusion through a conical twin-screw extruder, heating the PLA powder to 170 DEG C, carrying out extrusion through the conical twin-screw extruder, heating the ASA and the PLA powder under stirring to 90 DEG C, and carrying out extrusion through a single-screw extruder; thus, the synthetic resin tile is obtained through a three-layer coextrusion process. According to the invention, through compatibility of the PVC powder, the wood charcoal powder, the PLA powder and the bamboo-wood powder, the synthetic resin tile with high elasticity and degradation easiness is prepared.
