Abstract

The invention discloses an environment-friendly velvet film for shoes and a preparation method thereof, wherein the environmental-friendly velvet film for shoes sequentially comprises a surface velvet layer, a water-based PU surface layer and a thermosetting two-component solvent-free foaming layer from top to bottom. Floor. The invention adopts water-based PU resin and solvent-free resin, does not add other toxic and harmful organic chemical solvents, and is environmentally friendly. The film provided by the present invention is printed on the water-based PU velvet layer to improve the velvet feel of the surface layer of the film. On the premise of improving the velvet feel of the surface layer, a wear-resistant additive is added to the surface layer polyurethane to improve the wear-resistant and scratch-resistant performance. At the same time, the film itself has high hydrolysis resistance and high peel strength. It is a good substitute for four-way elastic synthetic leather for shoes.
