Abstract

The invention discloses a production method of a finished product combining TPU polyurethane and a mucous membrane, and relates to the technical field of lettering film production; in order to solve the problem of color that cannot be directly printed and modulated on a TPU injection mold; it specifically includes the following steps: confirming the finished product Material information, draw product drawings; make molding molds according to the drawings; prepare adhesive films based on raw material information and pass laser marking, die-cutting and high-frequency die-cutting; combine the produced adhesive films with the forming molds by hot-melting TPU polyurethane adhesive; remove After the colloid remaining on the product, the product is dried and shaped to obtain the final product; the raw material information includes the material and raw materials of the mucous membrane, and the mucous membrane is divided into a substrate layer, a separation layer, a transfer layer and an adhesive layer. The invention utilizes the hot-melt technology to combine the lettering film and the forming mold with TPU polyurethane backing, instead of directly using the mold for printing, and solves the problem that some unpopular colors cannot be printed on the TPU injection molding through the combination of the two.

Description

technical field [0001] The invention relates to the technical field of lettering film production, in particular to a production method of a finished product combining TPU polyurethane and a mucous membrane. Background technique [0002] TPU polyurethane is a thermoplastic polyurethane elastomer, also known as thermoplastic polyurethane rubber, commonly known as injection molding, thermoplastic polyurethane elastomer is a kind of elastomer that can be plasticized by heating and dissolved by solvent. , automotive, medical and health, pipe, film and sheet and many other fields, suitable for mass production of medium and small size components. The mucous membrane is a kind of lettering film with hot melt adhesive on the back, also known as the transfer film. The lettering film refers to the thermal transfer film that needs to be cut / engraved during the thermal transfer process. The lettering film has TPU elastic lettering film, gold Onion lettering film, laser lettering film, i...
