Abstract:
Disclosed are a waterproof and drainage integrated board, a forming machine and a forming process. A rack is provided with a first concave roller, a convex roller, a second concave roller and a mirror roller, the convex roller rolls relative to the first concave roller and the second concave roller, and the mirror roller rolls relative to the second concave roller. A drainage layer substrate of the present invention is extruded from a first extruder head, immediately follows the second concave roller after shaping to a bottom part, and is directly fused with a waterproof layer just extruded from a second extruder head and formed. By adjusting a gap between the second concave roller and the mirror roller to apply a certain pressure for pressing and calendering, the drainage layer and the waterproof layer are integrated. A hollow boss has good strength, and a bottom surface opening thereof is also closed by the waterproof layer. Even if the boss breaks and leaks, the waterproof layer is present to prevent leakage. In addition, the substrate and the fused waterproof layer has double layer thickness, which further improves the strength and waterproofness thereof.
