摘要
The present invention is an improved adhesive properties The thermoplastic polyurethane (TPU) relates to a method for producing a composition for film as, more specifically, by preparing a separate thermoplastic polyurethane (TPU) pellets was melted in the form of a composition in a thermoplastic polyurethane (TPU) substrate to prepare a modified form of the master batch of pellets containing silica and a polar polymer into the resin, maintaining an elastic force than conventional thermoplastic polyurethane (TPU) and yet far superior adhesion, thin-thick thermoplastic polyurethane pinhole phenomenon does not occur at the time of film production and also to replace the expensive imported, and the adhesion of the film For a composition for a thermoplastic polyurethane film according to the present invention, unlike the conventional operation method for bonding through a washing and pre-processing step by the toxic volatile solvent to reduce the error rate, the environment-friendly because it does not use the work area at all the volatile organic solvent can bring the effect to improve. ; and the production method of the composition for a thermoplastic polyurethane film was also added to improve the adhesive material at the time of the thermoplastic polyurethane to improve the adhesion with the conventional synthesis Since the processing method and system using a modified master batch non-small business application has a possible advantage in this, also, as needed at the time of manufacturing the modified master batch, regardless of the type of the thermoplastic polyurethane to be used by changing only the thermoplastic polyurethanes described It can be applied to various fields.
