Abstract

The utility model provides a black film for car window frame B post, includes facial mask layer, glue layer, bottom paper layer, the bonding of glue layer is passed through on bottom paper layer in the facial mask layer, the corner hem department of black film is equipped with a plurality of breachs, form a protruding membrane between the two adjacent breachs, and the outside width of this protruding membrane is greater than inboard width. The utility model discloses the breach that black film corner hem place set up can effectively release internal stress produced when pasting, can not form excessively tensile to the black film, can bordure or prevent the problem that the material rises to stick up during flexing point such as cornerite.

Description

A kind of black film for vehicle window frame b post

Technical field

This utility model is related to a kind of black film for vehicle window frame b post.

Background technology

Black film, also known as hiding black film (blackout film), belongs to one kind of feature automobile adhesive film, used in the car of automobile The positions such as post, window frame, replace paint to play role in decoration, can expand the vision of vehicle window, windshield.However, with this dress The widely using of trim, the problem brought therewith also becomes increasingly conspicuous.Particularly as follows: on client's assembly line, when black film is pasted on When on vehicle window frame b post, when angle position is slightly in an angle of 90 degrees, because the problems such as warp easily being occurred by film stretch effects itself, sternly Ghost image rings client's productive temp and prescription.

Utility model content

For the deficiencies in the prior art, this utility model be intended to provide a kind of solve above-mentioned technical problem for vapour The black film of window frame of automobile b post, makes the problem that original corner black film warps thoroughly be improved.Because corner flanging area becomes big, So that the initial viscosity of material is increased, the problem that material warps can be prevented in the bending position such as bound edge or cornerite.

For achieving the above object, this utility model adopts the following technical scheme that

A kind of black film for vehicle window frame b post, including face mask layer, glue layer, ground paper layer, described face mask layer passes through glue Layer is bonded on ground paper layer, is provided with some breach at the corner flanging of described black film, forms a convex film between adjacent two breach, and The outside width of this convex film is more than inboard width.

Preferably, each described breach is in u shape.

Preferably, the corner flanging of described black film is a depression side.

Preferably, the quantity of described u v notch v is 5.

The beneficial effects of the utility model are at least as follows:

This utility model removes can make the problem that original corner black film warps thoroughly be improved.Because black film corner flanging Produced internal stress when the set u v notch v in place can effectively discharge stickup, will not form excessive tensile to black film, can Prevent the problem that material warps in the bending position such as bound edge or cornerite.And, further, by making at black film corner flanging The outside width of convex film is more than inboard width, can increase the area being capable of bound edge, thus strengthening sticking strength, makes the first of material Beginning viscosity increases, and preferably solves the problems, such as that material warps.

Brief description

Fig. 1 is a structural representation of the black film for vehicle window frame b post of the present utility model.

Fig. 2 is another structural representation of the black film for vehicle window frame b post of Fig. 1.

In figure: 100, be used for the black film of vehicle window frame b post；10th, face mask layer；20th, glue layer；30th, ground paper layer；40th, corner Flanging；42nd, breach；44th, convex film.

Specific embodiment

Below in conjunction with accompanying drawing and specific embodiment, this utility model is described further:

Refer to Fig. 1 and Fig. 2, this utility model is related to a kind of black film 100 for vehicle window frame b post, including a facial film Layer 10, one glue layer 20 and a ground paper layer 30, described face mask layer 10 is bonded on described ground paper layer 30 by described glue layer 20, It is provided with multiple breach 42 at the corner flanging 40 of the described black film 100 for vehicle window frame b post.In one embodiment, each scarce Mouth 42 is in substantially u shape.

Form a convex film 44 between breach 42 described in adjacent two, and the outside width of this convex film 44 is more than inboard width.? In one embodiment, the quantity of described breach 42 is 5.

After monoblock black film 100 is pasted onto car door according to the size formulated, presses lightly in bound edge profile and about become 145 degree of folders Angle, exposes the profile of bound edge it is necessary to along car door profile, pressing black film 100 and about become 90 degree, to guarantee described 100 skies of black film Gas is discharged and is no pursed up, and finally pressing makes described black film 100 be pasted onto on door-plate completely, and described black film 100 bound edge region pressure Real, prevent from warping.360 degree of bound edge at least separately presses it is ensured that bound edge does not tilt for three times.Structure design after improvement can be wrapped The area on side is 2 times before improving, and increased adhesive strength, and decreases the dependence to film tensile property itself, thus keeping away Exempt from the risk that bound edge position black film 100 warps.

For a person skilled in the art, can technical scheme as described above and design, make other each Plant corresponding change and deform, and all these changes and deforms the guarantor that all should belong to this utility model claim Within the scope of shield.
