Abstract
The invention relates to the technical field of a production process of a hot melt adhesive, and in particular relates to a production process for laminating a hot melt adhesive with TPU (thermoplastic urethane). The production process comprises the following modes of: if a double-layer co-extruder is selected for extruding the hot melt adhesive and the TPU at the same time, laminating to form a membrane after the hot melt adhesive is adhered to the TPU, then forming and coiling; if a single extruder is selected for sequentially extruding the hot melt adhesive and the TPU, producing a single-sided misty or transparent hot melt adhesive product by adopting the mode of directly pressing an embossing roller by a rubber roll, then laminating the single-sided misty or transparent hot melt adhesive with the TPU to form a membrane, then forming and coiling; and if a single extruder is selected for sequentially extruding the TPU and the hot melt adhesive, producing a TPU product by adopting the mode of directly pressing an embossing roller by a rubber roll, then laminating the TPU with the hot melt adhesive to form a membrane, then forming and coiling. The membrane produced by the production process has the advantages of better flatness, less possibility of curliness, uniform surface lamination tension and no bubbles and wrinkles, thus the obtained product is more flat and beautiful.
Description
Technical field:
