Abstract

The invention provides an insert injection moulding decoration transfer printing foil with anti-yellowing performance. The insert injection moulding decoration transfer printing foil with anti-yellowing performance comprises a base film layer, a release layer, a color layer, an aluminium coated layer, and an adhesive layer which are laminated successively; the color layer is prepared from, by weight, 10 to 25 parts of low density polyethylene, 10 to 20 parts of high density polyethylene, 1 to 10 parts of polyurethane acrylate, 1 to 5 parts of epoxy acrylate, 1 to 10 parts of trimethylolpropanetriacrylate, 8 to 12 parts of methyl methacrylate, 20 to 60 parts of n-butyl methacrylate, 1 to 10 parts of polyethylene wax powder, 10 to 20 parts of polyamide, 10 to 25 parts of a diluent, 10 to 20parts of titanium dioxide, 0.1 to 2 parts of a dispersant, 1 to 30 parts of an anti-corrosive pigment, 5 to 10 parts of a toughening auxiliary agent, and 3 to 8 parts of an anti-yellowing auxiliary agent. According to a preparation method, acrylic resins of different amounts and different kinds are adopted so as to obtain the novel color layer; the toughening auxiliary agent and the anti-yellowing auxiliary agent are added, so that yellowing is avoided under certain heating requirements, and the anti-yellowing performance is improved greatly.

Description

technical field [0001] The invention relates to the technical field of transfer film, in particular to an insert injection molding decorative transfer foil with anti-yellowing performance. Background technique [0002] Insert molding decoration (INS) is still widely used in the automotive industry, although it is not as efficient as in-mold decoration (IMD). Insert injection molding decoration transfer technology is mainly used on injection molded parts with complex surface structures that cannot be applied by ordinary in-mold injection molding decoration technology. Thanks to this technology, surface decoration of many parts with complex surface structures becomes possible. [0003] Insert molding decorative transfer film (INS) with classic formula is widely used in the automotive industry all over the world. The unique flexibility enables the INS film to be applied to almost all surfaces with complex structures. Although the application performance is excellent, the ex...
