WATERPROOF AND WEAR-RESISTANT COMPOSITE FLOOR AND PRODUCTION METHOD
20250229520 · 2025-07-17 · ·

A production method for a waterproof and wear-resistant composite floor, comprising: first manufacturing a PVC composite layer preform (3); then performing a corona treatment and a punching treatment on a soft cushion layer (2); and finally, compounding, at one time, the PVC composite layer preform (3), the soft cushion layer (2) and a waterproof substrate layer (1) into one. Said process is simple and easy to implement, shortening the production cycle, reducing the manpower and material resources required by the production process and reducing the production cost; moreover, the waterproof and wear-resistant composite floor produced has a simple structure, and also has very good waterproof and wear-resistant performance; in addition, the waterproof and wear-resistant composite floor will not swell, and will also not split into layers or deform easily.
