Abstract

The utility model discloses an IMD (In Mold Decoration) film comprising a base layer, a release layer, a UV (ultraviolet) semi-solidification layer, a printing ink layer, and a bonding layer which are formed in an overlapped manner from the bottom up. The IMD film is adsorbed on the surface of a mold cavity through in-mold positioning and vacuum adsorption, and is bonded with plastic through the bonding layer after spotting injection molding; the release layer is separated from the UV semi-solidification layer automatically after high-temperature injection molding, so that the base layer is also separated from the UV semi-solidification layer, the printing ink layer and the bonding layer; and high polymers are rigidized and cross-linked through UV solidification, so that a UV layer is also bonded on the upper surface of the printing ink layer. Therefore, the efficiencies of abrasion resistance and scraping prevention are realized.

Description

A kind of in-mold transfer printing film

Technical field

The utility model relates to the heat transfer film field, relates to a kind of heat transfer film of in-mould injection in particular.

Background technology

Along with the develop rapidly of new and high technology, the application of hot transfer technique more and more widely, hot transfer technique specifically be divided into again hot pressing transfer technique and thermal dye sublimation transfer printing the technology; Wherein the hot pressing transfer technique generally is earlier with mode of printings such as wire mark, gravures; Picture and text are printed on heat-transferring printing paper or the plastic foil, through heating and pressurizing, picture and text are transferred on the article such as fabric, leather then; Thereby make to have corresponding pattern on fabric, the leather, and reach effect attractive in appearance.

But, traditional hot pressing transfer technique its only can be to article such as fabric, leather with pattern transfer, there is easy ruined hidden danger in the pattern of its formation, promptly it still can't reach the effect that the pattern that lets transfer printing obtain has wear-resisting and anti-scraping.

In view of this, the inventor has this case to produce to the above-mentioned defective further investigation in the existing hot transfer technique then.

The utility model content

The purpose of the utility model is to provide a kind of in-mold transfer printing film, and it is effective and have a printed layers of pattern transferring that it can go out wear-resisting and anti-scraping at the printed material surface forming.

In order to reach above-mentioned purpose, the solution of the utility model is:

A kind of in-mold transfer printing film wherein, comprises basalis, release layer, UV semi-solid preparation layer, printing ink layer and gluing layer, the from bottom to top folded successively type that is set as of this basalis, release layer, UV semi-solid preparation layer, printing ink layer and gluing layer.

Further, this basalis adopts the PET film.

Further, this printing ink layer comprises the color ink lay and covers the high temperature ink layer on the color ink lay.

After adopting said structure; The utility model relates to a kind of in-mold transfer printing film; It is located in mould, vacuum suction after mold cavity surface and mold-closing injection, promptly through gluing layer and bonding with plastic cement, this release layer just separates with UV semi-solid preparation layer after through injection moulding high temperature voluntarily; Promptly make basalis also separate with gluing layer with UV semi-solid preparation layer, printing ink layer; Then carry out UV curing once more and make the macromolecule sclerosis crosslinked, thereby make the upper surface that is bonded in printing ink layer also have the UV layer, so can reach the effect of wear-resisting and anti-scraping.

The specific embodiment

In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.

As shown in Figure 1; The structure cutaway view of its a kind of in-mold transfer printing film 100 for the utility model relates to; This in-mold transfer printing film 100 comprises basalis 1, release layer 2, UV semi-solid preparation layer 3, printing ink layer 4 and gluing layer 5, and the from bottom to top folded successively type that is set as of this basalis 1, release layer 2, UV semi-solid preparation layer 3, printing ink layer 4 and gluing layer 5.

This basalis 1 is as the carrier of release layer 2, UV semi-solid preparation layer 3, printing ink layer 4 and gluing layer 5 coatings, and preferably adopts the PET film, thereby has dimensionally stable, even tension, high temperature resistant and characteristics that light transmittance is high.

The coating of this release layer 2 for constituting by mould release, this mould release can keep solid state at normal temperatures and have stickiness, it is at the next fusible low-viscosity of setting that becomes of temperature, thus can be fast and basalis 1 and UV semi-solid preparation layer 3 be separated.

This UV semi-solid preparation layer 3 is that the UV hardened layer is not solidified to form fully, and it is solid-state but possesses certain softness and draftability, can be used to carry out the moulding in the mould.It also needs through UV curing once more follow-up, thereby improves the hardness and the wearability on surface, with the colored ink of protection the inside.

This printing ink layer 4, the core for whole transfer film need to prove; Based on technologic requirement, this printing ink needs all can bear high temperature nondiscolouring and decomposition, and is preferred; As shown in Figure 2, this printing ink layer 4 specifically also comprises high temperature ink layer 41 and color ink lay 42, and this high temperature ink layer 41 covers on the color ink lay 42; Can be through this high temperature ink layer 41 as the thermal insulation layer of color ink lay 42, and play the effect of protection color ink lay 42.

This gluing layer 5 is used for and printed material surface produces cohesion, cohere firmly to guarantee printing ink layer 4 and printed material surface, specifically the material of this gluing layer 5 need with the use of arranging in pairs or groups mutually of the material of printed article.

Like this; The utility model relates to a kind of in-mold transfer printing film 100; It is located in mould, vacuum suction after mold cavity surface and mold-closing injection, promptly through gluing layer 5 and bonding with the plastic cement on the printed material, this release layer 2 just separates with UV semi-solid preparation layer 3 after through injection moulding high temperature voluntarily; Promptly make basalis 1 also separate with UV semi-solid preparation layer 3, printing ink layer 4 and gluing layer 5; Then carry out UV curing once more and make the macromolecule sclerosis crosslinked, thereby make the upper surface that is bonded in printing ink layer 4 also have the UV layer, so can reach the effect of wear-resisting and anti-scraping.

Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
