Background

Injection molding is a very important molding mode in the existing manufacturing industry, at present, more and more daily necessities are used for injection molding products, the color and pattern of the existing injection molding part are changed only, the personalized design is lacked, and the change cannot be caused along with the change of light.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a decorative injection molding part, the surface of which has a light-variable effect, the surface color can change along with the change of the intensity of light, the function of reminding abnormal temperature can be realized, and a certain decorative function is also realized.

In order to achieve the purpose, the utility model provides the following technical scheme:

the utility model provides a decorate injection molding, includes base mould layer, light change layer, end chromatograph, tie layer and plastic layer, the base mould layer sets up the upper surface on light change layer, end the chromatograph sets up the lower surface on light change layer, the plastic layer passes through with end the color layer the tie layer bonds.

In one embodiment, the optically variable layer is prepared by mixing and modulating optically variable pigment and resin.

In one embodiment, the base color layer is comprised of one or more of a resin, a pigment, a filler, an adjuvant, or a solvent.

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

In one embodiment, the plastic layer is formed by injection molding.

In one embodiment, a protective diffusion layer is also included, the protective diffusion layer being disposed between the base color layer and the bonding layer.

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

The decorative injection molding piece can be formed by printing the base mold layer, the light change layer, the bottom color layer and the jointing layer and then is bonded with the plastic layer through the jointing layer, so that the surface of the injection molding piece utilizing the structure has a temperature sensing effect and also has a certain decorative effect.

Drawings

FIG. 1 is a schematic perspective view of the present invention;

1. a base mold layer; 2. a light-changing layer; 3. a ground color layer; 4. a protective expansion layer; 5. a bonding layer; 6. a plastic layer.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by one of ordinary skill in the art from the embodiments given herein without making any creative effort, shall fall within the scope of the present invention.

Referring to fig. 1, a decorative injection-molded part is provided, which includes a base mold layer 1, an optically variable layer 2, a ground color layer 3, a bonding layer 5 and a plastic layer 6, wherein the base mold layer 1 is disposed on an upper surface of the optically variable layer 2, the ground color layer 3 is disposed on a lower surface of the optically variable layer 2, and the plastic layer 6 and the ground color layer 3 are bonded by the bonding layer 5.

The photo-variable layer 2, the ground color layer 3 and the junction layer 5 can be sequentially printed on the basic die layer 1 through processes of silk screen or intaglio printing, relief printing and the like, the printed basic die layer is placed into an oven to be cured and baked by chemical solvents after being printed each time, after all printing is completed, a base material with a required shape can be obtained through modes of hot pressing die, punching die forming and the like, and then the base material is bonded with the plastic layer 6 through the junction layer 5 to be cured on the plastic layer 6.

Specifically, the optically variable layer 2 is prepared by mixing a optically variable pigment and a resin.

Specifically, the ground color layer 3 is composed of one or more of resin, pigment, filler, auxiliary agent or solvent; 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 light change layer 2, the ground color layer 3 and the jointing layer 5 are made into a base material with a required shape, the base material can be placed into an injection mold for injection molding, and in the injection molding process, the plastic layer 6 is adhered to the jointing layer 5 of the base material.

Specifically, the jointing layer is composed of a main agent and an auxiliary agent, wherein the main agent is a main material, a base material or a binding material; the auxiliary agents comprise curing agents, diluents, plasticizers, fillers, coupling agents, initiators, thickeners, anti-aging agents, polymerization inhibitors, stabilizers, complexing agents, emulsifiers and the like, and can also comprise flame retardants, foaming agents, antifoaming agents, colorants, mildewproof agents and the like according to requirements and purposes.

In one embodiment, a protective layer 4 is also included, the protective layer 4 being disposed between the base color layer 3 and the bonding layer 5. Wherein, protective layer 4 forms for UV gloss oil and PU gloss oil solidification, and is specific, and protective layer 4 can prevent to be washed away the printing ink in the photochromic layer 2 that the printing was accomplished and the base colour layer 3 when advancing to glue by high temperature, and wherein, the thicker the playing of seal protects and expands the effect and is bigger.

The decorative injection molding part can be formed by printing the base mold layer 1, the light variable layer 2, the ground color layer 3 and the jointing layer 5, and then is bonded with the plastic layer 6 through the jointing layer 5, so that the surface of the injection molding part using the structure has a temperature sensing effect, and also has a certain decorative effect.
