Abstract

The utility model discloses an anti PVC self-adhesion protection film that migrates, PVC self-adhesion protection film is including anti migration layer, function protective layer, adhesive linkage, printing ink layer, barrier layer and the self-adhesion layer that sets gradually. The utility model adopts gloss oil and crosslinked PMMA microspheres to prepare the anti-migration layer, which can prevent the plasticizer from migrating to the surface of the protective film to cause fogging phenomenon and improve the anti-adhesion and anti-scratch properties; the micro-spheres form a micron-sized concave-convex surface on the surface of the protective film, play a role in light scattering and form a matte surface with soft light.

Description

Anti-migration PVC self-adhesion protective film

Technical Field

The utility model relates to a surface protection film field, concretely relates to anti migration PVC self-adhesion protection film.

Background

In the processes of processing, assembling, storing and transporting commodities, the surfaces of parts and materials are often required to be protected to prevent the corrosion of harmful gases and microorganisms and avoid ultraviolet irradiation aging, dust pollution, mechanical scratch and the like, so that a protective film is required to be used for protecting a plurality of household appliances, high-grade furniture, decorative materials and the like during storage and transportation, and then the protective film is removed to achieve the effect of protecting the surfaces of the materials.

Polyvinyl chloride (PVC) films are one of the surface protective films commonly available on the market. In order to obtain a PVC film of suitable hardness, it is generally necessary to add a suitable amount of plasticizer. The plasticizer is mostly a liquid micromolecule assistant, and is easy to migrate and separate out, so that the phenomena of oily substances, fogging and the like appear on the surface of the film, and the appearance of a protected product is influenced.

SUMMERY OF THE UTILITY MODEL

The invention aims to overcome the defects of the prior art and provide an anti-migration PVC self-adhesion protective film.

The above object of the present invention is achieved by the following technical solutions:

the utility model provides an anti migration PVC self-adhesion protection film, is including anti migration layer, functional protection layer, adhesive layer, printing ink layer, barrier layer and the self-adhesive layer that sets gradually.

Preferably, the anti-migration layer is made of an anti-migration agent which is a mixture of gloss oil and crosslinked PMMA microspheres. The crosslinked PMMA microspheres have high hardness, can play the roles of adhesion resistance and scratch resistance when being dispersed on the surface of the film, have good barrier property, and effectively prevent the plasticizer from migrating to the surface of the protective film; the micro-spheres form a micron-sized concave-convex surface on the surface of the protective film, play a role in light scattering and form a matte surface with soft light.

Preferably, the function protective layer has set gradually antistatic layer and anti UV layer, anti UV layer with the adhesive layer meets.

Preferably, the barrier layer is a PVDF layer, a PVDC layer, or a PVOH layer. The barrier layer can prevent printing ink from permeating into the self-adhesive layer and a protected product, and the appearance of the product is kept clean.

The material for preparing the self-adhesive layer may be a material commonly used in the art for preparing self-adhesive protective films, such as a mixture of PVC and EVA.

Compared with the prior art, the utility model discloses following beneficial effect has:

the utility model adopts gloss oil and crosslinked PMMA microspheres to prepare the anti-migration layer, which can prevent the plasticizer from migrating to the surface of the protective film to cause fogging phenomenon and improve the anti-adhesion and anti-scratch properties; the micro-spheres form a micron-sized concave-convex surface on the surface of the protective film, play a role in light scattering and form a matte surface with soft light.

The present invention will be described in more detail with reference to the accompanying drawings and examples.

Drawings

Fig. 1 is a schematic structural view of the anti-migration PVC self-adhesion protective film of the present invention.

Detailed Description

In the embodiment, the structure of the anti-migration PVC self-adhesive protective film according to this embodiment is as shown in fig. 1, and includes an anti-migration layer 1, an antistatic layer 2, an anti-UV layer 3, an adhesive layer 4, an ink layer 5, a barrier layer 6, and a self-adhesive layer 7, which are sequentially disposed. The antistatic layer 2 and the anti-UV layer 3 constitute a functional protective layer.

The preparation of the migration-resistant PVC self-adhesive protective film can be carried out according to the following method:

preparing a functional protective layer consisting of an antistatic layer 2 and an anti-UV layer 3 by adopting a multi-layer co-extrusion compounding method, and then coating an anti-migration layer 1 on one side of the antistatic layer 2; printing ink layer 5 on barrier layer 6, add one deck adhesive layer 4 on the surface of ink layer 5 again, laminate adhesive layer 4 and anti UV layer 3, cover one deck self-adhesive layer 7 on the surface of barrier layer 6 at last. The prepared PVC self-adhesive protective film has good adhesion resistance and scratch resistance, and does not have the phenomenon of migration and fogging of a plasticizer.

It is obvious that the above embodiments of the present invention are only examples for clearly illustrating the present invention, and are not limitations to the embodiments of the present invention. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the claims of the present invention.
