As shown in fig. 9, a picture of a combination state of an injection molding piece and a peelable layer with a transparent structure is shown, from the picture, wherein the upper structure is a state of tearing and separating the peelable layer (in the figure, an upper layer held by a finger is the peelable layer, and a lower layer is the injection molding piece body) from the injection molding piece body, and at the moment, the surface of the injection molding piece body presents a three-dimensional texture structure; the lower structure is characterized in that the injection molding body and the peelable layer are not peeled off, at the moment, the three-dimensional texture structure is not displayed, and the three-dimensional texture structure can be obviously displayed on one surface of the injection molding body when the injection molding body and the peelable layer are separated.
The peelable layer is a structure formed by compounding a carrier layer and a three-dimensional texture layer, the structure is prepared firstly, then is placed in an injection mold, and is mutually extruded and combined with a molten injection molding material under high temperature and high pressure conditions, so that the three-dimensional texture structure in the three-dimensional texture layer is transferred onto the surface of the injection molding; the material and performance of the injection molding part are different from those of the peelable layer, and the formed layers are different from each other, so that the peelable layer can be torn off after injection molding is finished based on the above difference, or can be torn off when the peelable layer is needed to be used as a protective film to be combined with the injection molding part and the like (refer to the state of fig. 9 specifically).
In order to improve the stripping effect between the strippable layer and the injection molding part, a strippable agent such as a commercially available organic silicon stripping agent is arranged in the three-dimensional texture layer, and the mass addition amount of the strippable agent in the three-dimensional texture layer can be 1-10%, so long as the stripping agent can be more easily separated from the injection molding part, and the type and the addition amount of the strippable agent can be realized; by adopting the mode, after the injection molding of the injection molding part is finished, the separation between the strippable layer and the injection molding part can be more convenient, and the integrity of the three-dimensional texture transferred to the surface of the injection molding part is ensured.
