A transfer printing film for the surface of body-building equipment and its preparing process, includes a substrate layer; a polyvinyl alcohol glue layer located on the base layer; the release layer is positioned on the polyvinyl alcohol adhesive layer and comprises polydimethylsiloxane or polymethyl methacrylate; a printed layer on the release layer; and an adhesive layer on the printing layer; during preparation, firstly, the base layer is subjected to corona discharge treatment, and then, glue is applied to one side of the base layer by using polyvinyl alcohol, wherein the solid content of the polyvinyl alcohol is 4-5%, and the glue application amount is 2-4g/m 2 . The production process is simple, and the prepared transfer printing film has the advantages of high adhesion, high temperature resistance, scratch resistance, water resistance, good weather resistance and the like. |
