To achieve the above object, the utility model provides the following technical solutions:

A decorative injection molded part comprises a base mold layer, an optically variable layer, a base color layer, a bonding layer and a plastic layer, wherein the base mold layer is arranged on the upper surface of the optically variable layer, and the base color layer is arranged on the upper surface of the optically variable layer. On the lower surface of the optically variable layer, the plastic layer and the base color layer are bonded through the bonding layer.

In one embodiment, the photovariable layer is prepared by mixing photovariable pigments and resins.

In one embodiment, the base color layer is composed of one or more of resins, pigments, fillers, auxiliary agents or solvents.

In one embodiment, the base mold layer is a PET transparent film or a PC transparent film.

In one embodiment, the plastic layer is injection-molded.

In one of the embodiments, a preservation layer is further included, and the preservation layer is disposed between the base color layer and the bonding layer.

In one embodiment, the protective layer is formed by curing UV varnish and PU varnish.

The decorative injection molded part of the utility model can be bonded to the plastic layer through the bonding layer after the base mold layer, the optically variable layer, the background color layer and the bonding layer are printed and formed, so that the surface of the injection molded part using this structure has a temperature-sensing effect. It also plays a certain decorative role. When it is in sunlight or a lighting area containing ultraviolet light, its surface color will change with the intensity of the ultraviolet light source, and the original color can be restored when the ultraviolet light source is absent.

1. Base model layer; 2. Optical variable layer; 3. Background layer; 4. Preservation layer; 5. Bonding layer; 6. Plastic layer.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work fall within the scope of the present invention.

Referring to FIG. 1 , a decorative injection molded part is provided, including a base mold layer 1 , an optically variable layer 2 , a base color layer 3 , a bonding layer 5 and a plastic layer 6 , and the base mold layer 1 is disposed on the optically variable layer. 2 , the base color layer 3 is disposed on the lower surface of the optically variable layer 2 , and the plastic layer 6 and the base color layer 3 are bonded through the bonding layer 5 .

The optical variable layer 2, the background layer 3 and the bonding layer 5 can be printed on the base mold layer 1 in sequence by silk screen or gravure, letterpress printing and other processes. After all the printing is completed, the substrate of the desired shape can be obtained by hot stamping, die-cutting, etc., and then the substrate is bonded to the plastic layer 6 through the bonding layer 5 to be cured on the plastic layer 6 .

Specifically, the photo-variable layer 2 is prepared by mixing photo-variable pigments and resins.

Specifically, the base color layer 3 is composed of one or more of resins, pigments, fillers, auxiliary agents or solvents; the base mold layer 1 is a PET transparent film or a PC transparent film.

Specifically, the plastic layer 6 is formed by injection molding. After the optically variable layer 2, the base color layer 3 and the bonding layer 5 are formed into the substrate of the desired shape, they can be put into the injection mold for injection molding. During the injection molding process, the plastic layer 6 and the bonding layer 5 of the substrate are adhered combine.

Specifically, the bonding layer is composed of a main agent and an auxiliary agent, and the main agent is a main material, a base material or a sticky material; the auxiliary agents include a curing agent, a diluent, a plasticizer, a filler, a coupling agent, an initiator, a Thickeners, antioxidants, polymerization inhibitors, stabilizers, complexing agents, emulsifiers, etc., can also include flame retardants, foaming agents, defoaming agents, colorants and antifungal agents according to requirements and uses. In the manufacturing process, producers can choose according to their needs.

In one embodiment, a preservation layer 4 is also included, and the protective layer 4 is disposed between the base color layer 3 and the bonding layer 5 . Wherein, the protective layer 4 is formed by curing UV varnish and PU varnish. Specifically, the protective layer 4 can prevent the ink in the printed optically variable layer 2 and the base color layer 3 from being washed away when the glue is fed at high temperature. , Among them, the thicker the printing, the greater the expansion effect.

The decorative injection molding of the present invention can be bonded to the plastic layer 6 through the bonding layer 5 after the base mold layer 1, the optically variable layer 2, the background color layer 3 and the bonding layer 5 are printed and formed, so that the injection molding using this structure can be formed. The surface has a temperature-sensing effect and also plays a certain decorative role. When it is in sunlight or a lighting area containing ultraviolet light, its surface color will change with the intensity of the ultraviolet light source, and the original color can be restored when the ultraviolet light source is absent. .
