The utility model discloses a keyboard sticky tape with halo effect explains below with the accompanying drawing, as shown in fig. 1, fig. 2, it includes the white substrate 1 unanimous with the keyboard profile, white substrate 1 has the transmittance and is formed with keyboard hole 11 on it, white substrate 1's first face 12 is provided with black light shield layer 2, be formed with on the black light shield layer 2 with every keyboard hole 11 the same and coaxial hole of dodging 21 of shape, the area of dodging hole 21 is greater than keyboard hole 11, the border position of black light shield layer 2's surface and the region of dodging between the hole 21 are attached with first adhesive layer 3, the surface of black light shield layer 2 and first adhesive layer 3 cover under release film 4; the edge position of the second surface 13 of the white base material 1 is provided with a second adhesive layer 5, and the second surface 13 of the white base material 1 and the second adhesive layer 5 are covered by a support film 6.

The white base material 1 is used for supporting, can be made of various known white materials with certain transmittance, and the shape of the white base material can be adaptively designed according to the shapes of various keyboards, for example, the white base material can be used for keyboards of various known brands and notes, preferably, the white base material 1 is a white polyester film, the thickness of the white polyester film is not more than 50 micrometers, and the transmittance of the white polyester film is 15% -31%, so that after subsequent assembly, a certain light can be transmitted through a square frame of an outer leakage area which is not shielded by the black light shielding layer 2, a certain halo effect is displayed around each key, and each key area can be displayed more visually and is more attractive in appearance.

The black shading layer 2 may be various known shading materials, such as a black shading tape, but when the black shading tape is used, the processing of the product is relatively complicated, and it is difficult to ensure the position accuracy of each avoiding hole 21 and the keyboard hole 11, therefore, the black shading layer 2 preferably uses black ink to perform screen printing or spraying or the like to obtain at least one layer of black ink 22, the black ink preferably uses slow volatilization type ink and semi-gloss type ink, and because the shading effects of the inks with different thicknesses are different, the best shading effect can be obtained when the black ink 22 is two layers according to the research on the shading effect.

The first adhesive layer 3 is used for bonding the white base material 1 with other objects, and due to material differences of different bonding positions, as shown in fig. 1 and 3, the first adhesive layer 3 includes a plurality of inner double-sided adhesive tapes 31, a plurality of outer double-sided adhesive tapes 32 located on the outer sides of the inner double-sided adhesive tapes 31, and a plurality of water adhesives 33 located between the avoiding holes, which are arranged at positions close to two short sides of the white base material and in gaps.

The inner double-sided adhesive tape 31 is made of black double-sided adhesive tape, and in order to increase the shock absorption and dust prevention performance after the product is pasted, as shown in fig. 4, the inner double-sided adhesive tape 31 includes foam 311 and glue 312 and 313 coated on two sides of the foam, and the peel strength of the inner double-sided adhesive tape 31 is not less than 1N/mm at 180 °.

The two-sided adhesive tape 33 in outside with two minor faces parallel and level of white substrate, its preferred transparent double faced adhesive tape that adopts, it includes the PET substrate and coats the tackified ya keli glue of its two sides, and its bonding strength to various materials is not less than 3N/cm to can guarantee that the both ends border position of white substrate can paste more firmly, avoid the problem of the perk that comes unstuck.

In addition, in order to adapt to the height difference of different adhering surfaces and enable both the inner double-sided adhesive tape 31 and the outer double-sided adhesive tape 32 to be stably adhered to the adhering surfaces, as shown in fig. 2 and 3, the thickness of the outer double-sided adhesive tape 32 is smaller than that of the inner double-sided adhesive tape 31, and a certain distance is kept between the inner double-sided adhesive tape 31 and the outer double-sided adhesive tape 32.

The glue 33 can be any known glue material, for example, the glue can be made of SP-7533 model glue manufactured by 3M company, and can be obtained by printing, spraying and the like, so that the glue is also considered to be relatively sticky to other glue materials, and has good viscosity, environmental protection, harmlessness and easy product processing.

As shown in fig. 1 and 5, the release film 4 is used for protecting the white substrate 1, the black light shielding layer 2 and the first adhesive layer, and has a avoiding hole 44 consistent with the keyboard hole 11, and has handle portions 45 and 46 extending to the outer sides of two short sides of the white substrate 1, such a design can provide an operating space for the mounting operation of two hands when in use, and meanwhile, the handle portions 45 and 46 are located at two ends of the short sides, so that the release film 4 is not easily peeled from the first adhesive layer 3.

In addition, the release film 4 may be a complete film body, or may be formed by splicing a plurality of film bodies, and preferably, as shown in fig. 5, it includes two spliced monomer films 41,42, and the two monomer films 41,42 are obtained by cutting a complete release film from an intermediate position; the edges 412 and 422 spliced by the two monomer films 41 and 42 are respectively provided with the adjacent pull lugs 411 and 421 extending to the outside of the white base material 1, and the stress directions F1 and F2 of the two pull lugs 411 and 421 during tearing off keep an included angle of 90-180 degrees, so that the design is adopted, because when in use, one pull lug 411 and 421 can be respectively grasped by two hands, and the pull lugs are pulled in opposite directions, the tearing off of the two monomer films 41 and 42 can be simultaneously realized, the tearing off efficiency is high, and the operation is more convenient.

The monomer films 41,42 are preferably made of PET substrate, and the peeling force is preferably between 30 ± 8g/25mm, so that the higher peeling force is adopted because the adhering area of the first adhesive layer 3 and the monomer films 41,42 is relatively small, and therefore if the release paper with lower peeling force is adopted, the release paper is easily separated from the first adhesive layer 3, and the subsequent adhering operation is inconvenient.

Further, during the use of the product, the different outer double-sided adhesive tapes 32 may not be attached at one time, and may be attached in several times, in this case, if the release film 4 is integral, the outer double-sided adhesive tapes 32 that do not need to be attached will not be protected, so that the adhesive surface is easily contaminated, on the other hand, the outer double-sided adhesive tapes 32 that leak outside will interfere with the attaching operation, so as shown in fig. 5, the release film 4 is made to include a split film 43, the split film 43 covers several of the outer double-sided adhesive tapes 32 and has a portion extending to the outside of the white base material, preferably it covers two of the outer double-sided adhesive tapes 32 located at the bottom, and, since it needs to be torn off after use, in order to avoid taking off the split film 43 when the two monomer films 41,42 are torn off, therefore, preferably, the peeling force of the split film 43 is greater than the monomer film 41,42, particularly between 40 and 65g/25mm, thereby effectively ensuring the bonding stability of the outer double-sided adhesive tape 32 bonded with the split film 43.

As shown in fig. 1 and fig. 6, the second adhesive layer 5 includes a plurality of transparent adhesive strips 51,52 attached to two short sides of the white base material, which may be double-sided adhesive, preferably water adhesive, for example, SP-7533 glue manufactured by 3M company, and may be obtained by printing, spraying, etc., so that the water adhesive is also considered to be relatively sticky to other adhesive materials, which is good in viscosity, environmentally friendly, harmless, and easy to process the product.

The support film 6 is used for providing support and protecting the white base material 1 and the second adhesive layer 5, and as shown in fig. 1, has the same shape as the white base material 1, namely, has corresponding relief holes 62 thereon, and has a handle 61 extending to the outside of the white base material 1 for facilitating the peeling operation in the subsequent use; it may be any known release film material, but since the area to which the second adhesive layer 5 is bonded is small, it is preferable to use a material having a high peel force, preferably a peel force of 30 ± 8g/25 mm.

Meanwhile, when the product is used, because some corner areas may have the requirement of avoiding or some corner attaching positions, at this time, if the white base material 1 is of an integral structure, although the adhesive has certain deformation capacity, the bent angle area inevitably has wrinkles and other conditions, so that the adhesion is not smooth and firm, and simultaneously, in actual attachment, the protective film cannot be removed at the same time as the entire attachment because of the above-mentioned avoidance or corner position, and therefore, as shown in FIGS. 6 and 7, notches 16 and 17 are formed near the bottom edge 18 at both short sides 14 and 15 of the white base material 1, a light-shielding double-sided tape 53 is attached to a region between the notches 16 and 17 and the bottom edge 18, the light-shielding double-sided tape 53 is covered with a protective film 63, and the protective film 63 has a handle 631 extending out of the light-shielding double-sided tape 53.

Because the size of the protective film 63 is very small, in order to avoid peeling from the light-shielding double-sided tape 53 caused by reverse sticking when the protective film is stuck, the light-shielding double-sided tape 53 adopts a black PET substrate and acrylic adhesives coated on two sides of the substrate, the 180-degree peeling force of the black PET substrate is not less than 0.3N/mm, meanwhile, the protective film 63 is preferably a double-sided release film, the peeling force of the protective film is 8 +/-5 gf/25mm, and therefore the processing is convenient and the sticking stability of the protective film 63 and the light-shielding double-sided tape 53 can be ensured.

Finally, because whole texture is softer and is out of shape easily, hardly guarantees to paste the position progress when attaching, consequently, for the accurate location and attached when using of convenience, as shown in figure 1, be formed with a set of locating hole 7 on white substrate 1, black light shield layer 2, from type membrane 4 and the support membrane 6 to fix a position through locating hole 7 when being convenient for use.

When the product is used, the supporting film is firstly peeled off through the handle 61, then the two hands respectively grasp the handle parts 45 and 46 at the two ends of the release film 4, the whole product is moved, the product is positioned through the positioning hole 7 and then is pasted through the second adhesive layer, and then the pasting of the shading double-sided adhesive tape 53 is carried out after the protective film 63 is torn off; after one surface mounting is finished, the two hands respectively grasp the pull lugs 411 and 421 of the two monomer films, apply force in the opposite direction, and after the monomer films are torn off, the monomer films are attached to the part to be connected; then the split film is torn off and bonded with other parts. Of course, the above usage process may also be adjusted according to a specific application scenario, and is not limited only.

The following specifically explains the processing method of the keyboard adhesive tape with the halation effect, which comprises the following steps:

and S1, printing the second adhesive layer 5 at the set position of the support film material, wherein the printing process is a known technology and is not the main point of the scheme, and the printing process is not repeated herein, and the support film material can continuously move forward as a transport material and continuously print the second adhesive layer 5 on the material.

S2, attaching the white base material to the supporting film material and the second adhesive layer 5, and specifically, pressing the white base material, the supporting film material and the second adhesive layer 5 together by a pressing roller.

S3, printing at least one layer of black ink, preferably two layers of black ink on the white base material, wherein the black ink has the shape of a black shading layer, the finger touch drying time of the black ink during drying is 4-6 minutes, and the complete drying time is 30 +/-2 minutes, because the ink used in the scheme is slow volatile ink, the finger touch drying needs to be carried out in an oven at 80 ℃ and the drying is carried out for about 5 minutes by circulating warm air; completely drying, namely drying in an oven at 90 ℃ for about 30 minutes by circulating warm air; because the ink needs a long time for drying, continuous production is not convenient to carry out on a production line, and therefore, during actual processing, the black ink can be printed on the white base material firstly and then attached, and therefore, the continuous production can be carried out to improve the processing efficiency.

S4, transferring and pasting the inner side double-sided adhesive tape raw material, the outer side double-sided adhesive tape raw material and the printing water adhesive 33 at a specific position of the black ink, wherein the inner side double-sided adhesive tape raw material and the outer side double-sided adhesive tape raw material are respectively an integral adhesive tape and are cut into a plurality of parts for keeping gaps at the upper position; the black ink, the white base material, the inner double-sided adhesive tape raw material and the outer double-sided adhesive tape raw material are cut according to the shape of the white base material 1, waste materials in a non-product area are removed, and therefore the shapes of the inner double-sided adhesive tape and the outer double-sided adhesive tape of the shape base frame of the white base material 1 are obtained, and therefore the design is achieved, on one hand, the processing technology of the inner double-sided adhesive tape and the outer double-sided adhesive tape can be simplified, on the other hand, the processing difficulty can be reduced, and the processing; moreover, the transfer process is a known technique in the art, and is not the key point of the scheme, and is not described again.

However, when the inner side double-sided adhesive tape raw material and the outer side double-sided adhesive tape raw material are manufactured, the adhesive tape raw material needs to be cut in two steps, namely, the local outline of the adhesive tape raw material is cut firstly, and then the remaining outline of the adhesive tape raw material is cut, for example, three sides of the adhesive tape raw material are cut firstly, and then the remaining side is cut.

And S5, transferring the separating film 43 on the outer double-sided adhesive tape 32 on two sides of the lowest layer, wherein the transferring is also known in the art and is not described in detail herein.

And S6, attaching release film materials on the black ink, the inner double-sided adhesive tape 31, the water adhesive 33 and the outer double-sided adhesive tape 32, cutting the release film materials to obtain two monomer films 41 and 42, and removing the release film materials in the non-product area.

The reason why the split film 43 is adhered first and then the two monomer films 41 and 42 are processed is that the split film has a larger peeling force and is less likely to peel off from the adhesive, and the two monomer films 41 and 42 have a relatively smaller bonding strength with the first adhesive layer and are more likely to peel off and are susceptible to subsequent processing.

And S7, cutting the supporting film material and the white base material, cutting off the part of the supporting film material corresponding to the light-shielding double-sided adhesive tape 53, and forming the cuts 16 and 17 on the white base material 1, wherein the cutting can be realized by the height, and the details are not repeated for the known technology.

S8, the light-shielding double-sided tape 53 is transferred to the cut-off portion of the support film material, and the cutting step of the light-shielding double-sided tape 53 is the same as the two-step cutting step of the step S4, which is not described herein again.

S9, attaching a protective film 63 on the light-shielding double-sided tape 53, where the attaching process is still known in the art and is not described in detail.

And S10, cutting the support film material to obtain the support film.

Of course, the above-mentioned reference numerals of S1 to S10 do not limit the processing procedure of the present embodiment, and the processing sequence may be adjusted, for example, after attaching a light-shielding double-sided tape to a white base material and attaching a protective film, the other side of the white base material may be processed; or printing black ink on a white base material, sticking a first adhesive layer and then processing the structure on the other side; the optimal method in the scheme is that the whole process automatic processing can be carried out through automatic equipment so as to improve the processing efficiency; and, finally, a step of punching a positioning hole 7 on the product may be included.

The utility model has a plurality of implementation modes, and all technical schemes formed by adopting equivalent transformation or equivalent transformation all fall within the protection scope of the utility model.
