Claim 2:
3. A method for preparing the wiring trough of claim 1, comprising:
Step 1: obtaining a mixture of raw material by placing 99 parts of PVC resin, 3 parts of a combined heat stabilizer, 4 parts of an anti-impact agent, 2 parts of a lubricant and 4 parts of a flame retardant in a mixing mechanism;
Step 2: placing the mixture obtained in step 1 into a heating device, heating the mixture at temperature 110° C.-120° C., cooling the mixture and letting it sit for 24 hours;
Step 3: obtaining the wiring through by placing the mixture into two twin-screw extruders for extrusion, plasticizing and molding, thereby enhancing the wood feeling of the wiring trough and achieving the multi-color of the wiring trough; cutting the wiring trough to desired length.
