The black single-double-sided tape with the shading function of the shading tape adopts a black film manufactured by a unique printing process as a base material, has excellent shading property and insulating property, is usually applied to fixing of an LCD and a backlight source, and is a general name, and is divided into shading tapes of various types and colors.

However, with the demand of process development, the demand of the light-shielding tape gradually increases, and the performance requirements also increase day by day, the light-shielding effect of the existing light-shielding tape is not ideal, and the adhesion layer is adhered to the contact surface of the object for a long time, which easily causes the base layer and the adhesion layer to fall off under the influence of external force, and further causes the light-shielding effect to be poor and the service life of the product to be reduced.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a shading sticky tape has solved the problem that the above background art mentioned.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a shading sticky tape, includes the sticky tape main part, the sticky tape main part is from last to being equipped with first protective layer, first adhesion layer, basic unit, second adhesion layer, second protective layer down in proper order, the left and right sides at first adhesion layer bottom and second adhesion layer top all is equipped with the bump, the left and right sides of basic unit top and bottom all is equipped with the pit.

Preferably, first protective layer and second protective layer are PET and leave the type rete, from the type membrane and contact with the adhesion layer, prevent the damage of adhesive, adhere to and can demonstrate extremely light and stable from the type power on the adhesive surface, can be according to different required type membrane from the type power, keep apart the viscidity that the product glued different, from the corresponding adjustment of type power, make it reach extremely light and stable from the type power when peeling off.

Preferably, the first adhesion layer and the second adhesion layer are both acrylic acid adhesive layers, and the acrylic acid adhesive has the advantages of high strength, impact resistance, good weather resistance, oil surface adhesion, convenience in use, strong impact resistance and shearing force and the like.

Preferably, the basic unit is black PET film layer, adopts black coating printing, and through the matte treatment, shielding light source, its shading performance is superior, and the material is soft, pastes firmly, and difficult upwarping adopts black coating printing simultaneously, and the shielding nature is good, and black coating insulating nature is good.

Preferably, bump and concave point are for corresponding the setting, and the laminating links up each other, and bump that adhesion layer both sides were equipped with and the concave point that basic unit top and bottom were equipped with laminate each other for the contact surface of adhesion layer and basic unit both sides increases, and then increases the fastness that adhesion layer and basic unit are connected.

The utility model provides a shading sticky tape. The method has the following beneficial effects:

(1) this shading sticky tape, sticky tape main part can be used to LED and LCD display screen frame for two-sided adhesion and bordures, black PET material basic unit, shielding light source, and its shading performance is superior, and the material is soft, pastes firmly, is difficult for upwarping.

(2) This shading sticky tape, the bump that adhesion layer both sides were equipped with and the concave point that base course top and bottom were equipped with laminate each other for the contact surface of adhesion layer and base course both sides increases, and then increases the fastness that adhesion layer and base course are connected, prevents that the use of long-time product from leading to the phenomenon of droing to appear in base course and adhesion layer under the influence of external force, this operation increases its life.
