Description

Decorating film

Technical field

This utility model relates to decorating film.

Background technology

Decorating film is generally used for packing article or being attached at article surface, is such as attached to automobile, roof etc., to increase thing Product aesthetic property and ruggedness.

Existing decorating film is easier to scratch, and after scratching, whole thin film to be changed, and compares waste.

Utility model content

The purpose of this utility model is to provide a kind of decorating film, also has only to removable parts after scratching, cost-effective.

Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of decorating film, bag Include be sequentially connected with a PU layer, PVDF layer, a PMMA layer, the edge of described PMMA layer PVDF layer side dorsad is arranged Annular flange flange, described annular flange flange intermediate row is had to be furnished with spaced projection, the peak of described projection and annular flange flange The end face of a PMMA layer is in the same plane dorsad, the peak of a described projection and annular flange flange PMMA layer dorsad End face is all covered with pressure sensitive adhesive, and described pressure sensitive adhesive connects the 2nd PU layer, and described 2nd PU layer connects the 2nd PMMA layer.

The when of use, a PU layer bonds with the workpiece needing decorating film, and a PU layer is mainly used in setting, its tool Having good ruler stability, such PU layer is not easy deviation or fold with workpiece when of bonding；PVDF layer is high temperature resistant, Weather-proof, anti-ultraviolet, and a PMMA layer asepsis environment-protecting, have good chemical stability and a weatherability, but its light transmittance Height, ultraviolet easily injects, therefore PVDF just can ultra-violet radiation resisting, play a protective role；Annular flange flange guarantee is set 2nd PU layer and the adhesion strength of a PMMA layer, and on the one hand arranging of projection play the effect supporting the 2nd PU layer, separately On the one hand the bonding making the 2nd PU layer and a PMMA layer is a connection, facilitates the 2nd PU layer to separate with annular flange flange, when After 2nd PMMA layer is scratched, can be taken off together with the 2nd PU layer by the 2nd PMMA layer, the 2nd PMMA layer has good simultaneously Good dimensional stability, therefore facilitates the 2nd new PMMA layer bonding with annular flange flange, is not susceptible to skew；In addition the 2nd PU Layer is wear-resisting, promotes the service life of whole decorating film.

Further, through 2nd PMMA layer and a through hole for the 2nd PU layer is also included.

Arranging of through hole facilitates insertion instrument, it is simple to the 2nd PU layer separates with annular flange flange.

Further, a described PU layer is co-extruded by three layers of PU film.

Further, described PVDF layer is co-extruded by double-deck pvdf membrane.

Strengthen a PU layer and the intensity of PVDF layer.

Further, described projection is hemispherical projections.

Hemispherical projections anti-pressure ability is strong, and little with the bond area of the 2nd PU layer, is conveniently taken off by the 2nd PU layer.

Further, described projection, annular flange flange and a PMMA layer are one-body molded.

It is arranged such intensity higher.

In sum, this utility model has the advantages that this utility model simple in construction, cost-effective.

Accompanying drawing explanation

Fig. 1 is the structural representation of embodiment.

Reference: 1, a PU layer；2, PVDF layer；3, a PMMA layer；4, annular flange flange；5, protruding；6, the 2nd PU Layer；7, the 2nd PMMA layer；8, through hole.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is described in further detail.

This specific embodiment is only that it is not to restriction of the present utility model, ability to explanation of the present utility model The present embodiment can be made after reading this specification by field technique personnel as required does not has the amendment of creative contribution, but As long as all being protected by Patent Law in right of the present utility model.

As it is shown in figure 1, include a PU layer 1 from bottom to top, PVDF layer the 2, the oneth PMMA layer 3, a PU layer 1, PVDF Layer the 2, the oneth PMMA layer 3 is attached by the way of heat bonding, and wherein a PU layer 1 is co-extruded by three layers of PU film, PVDF Layer 2 is co-extruded by double-deck pvdf membrane, and a PMMA layer 3 is made up of PMMA film.

The edge of the oneth PMMA layer 3 PVDF layer 2 side dorsad is provided with annular flange flange 4, between annular flange flange 4 intermediate row is furnished with Every the projection 5 arranged, protruding 5 is hemispherical projections, and projection 5, annular flange flange 4 and a PMMA layer 3 are one-body molded.

2nd PU layer 6 is bonding with the peak of annular flange flange 4 and protruding 5 by pressure sensitive adhesive, the 2nd PMMA layer 7 and the 2nd PU Layer 6 heat bonding form, and arrange through 2nd PMMA layer 7 and the 2nd PU layer 6 of a through hole 8, and the 2nd PU layer 6 is PU film, the 2nd PMMA Layer 7 is PMMA film.

After the 2nd PU layer 6 is scratched, in inserting through hole 8 by instrument and stretch into the gap between protruding 5, work afterwards Tool abuts the 2nd PU layer 6 and outwards pulls so that the part of the 2nd PU layer 6 centered by through hole 8 and projection 5, annular flange flange 4 points From, after the 2nd PU layer 6 is partially separated with annular flange flange 4, can be from annular flange flange 4 part, by the 2nd PU layer 6 together with second PMMA layer 7 is torn, the 2nd PU layer 6 and the 2nd PMMA layer 7 the most more renewed.
