Abstract

The utility model discloses a double-sided tape, which comprises a release paper layer consisting of a base-body carrying layer and an upper anti-sticking layer and a lower anti-sticking layer applied on the upper surface and the lower surface of the base-body carrying layer, and an adhesive layer applied on the upper surface of the release paper layer. The double-sided tape is characterized in that the adhesive layer consists of independent pressure-sensitive adhesive film units which have the same thickness and are arranged continuously and uniformly. Because the adhesive layer is designed into the structure of the independent pressure-sensitive adhesive film units in continuous and uniform arrangement, the adhesive films of the adhesive layer can be easily pulled or cut off by the lifting of a coater tape box when the double-sided tape is shaped into a drum with a core and is mounted in the coater box body for the surface coating of a paper sheet or an object, thereby obviating the degumming and thread drawing of the prior double-sided tape which easily arise in use, and ensuring the coating tidiness and cleanness of the adhesive films.

Description

A kind of double sticky tape

Technical field

The utility model relates to the double sticky tape in the stationery, is meant that especially a kind of reel shape belt carcass of making is installed on the double sticky tape that uses in the applicator box body.

Background technology

At present, simultaneously apply at off-style paper layer and be connected with an adhesive-layer a kind of comprising by a separate-type paper, made reel shape belt carcass by coiling then and be installed on the double sticky tape that uses in the applicator box body, because it is easy to use, is widely used for the bonding of paper or object by people.But, the adhesive-layer of its adhesive tape of currently available products is to be coated on the off-style paper layer equably continuously when producing, in actual use, see Fig. 4～shown in Figure 5, the adhesive-layer glued membrane of adhesive tape along with the tape drum head on paper or body surface, exert pressure the back shifting movement effect, disengaging is transferred to paper or body surface with the connection of off-style paper layer, when reaching the predetermined position, with carrying on the tape drum head adhesive-layer glued membrane is broken, but because adhesive-layer glued membrane tool extensibility, in breaking process, easily produce and drag glue wire drawing phenomenon, and then cause location, gluing position not good, even polluted paper or body surface that desire attaches.

Use shortcoming at above-mentioned double sticky tape existence, my patent application formerly, Chinese invention patent application number 200810200920.2, currently available products is improved, its structure is: a kind of double sticky tape, comprise the off-style paper layer that the last adherent layer that is connected by upper and lower two surface-coated of ribbon matrix layer and its and following adherent layer are formed, upper surface coating at off-style paper layer is connected with adhesive-layer, it is characterized in that: described adhesive-layer is identical by thickness, and the pressure sensitive adhesive point of arranging that is equally spaced is formed.The double sticky tape of this application for a patent for invention is the former adhesive-layer of coating on the separate-type paper to be improved by the strip structural adhesive layer that links to each other continuously be designed to the point-like structural adhesive layer that is equally spaced and arranges, maintain certain clearance between the point-to-point glue-line, thus solved that currently available products exists drag glue wire drawing phenomenon.But also there is certain deficiency in the product of this patent application technology, because of after adhesive-layer is designed to point-like, because point-like adhesive-layer glued membrane unit exists the gap more each other, be coated in actual use by the viscose glue area occupied on sticking paper or the object unit surface and reduce, cause the bonding strength between the sticky object to decrease, can't be suitable for the occasion that bonding strength is had relatively high expectations than the bonding strength of using the currently available products double sticky tape.

Chinese utility model patent ZL200520113516.3 discloses a kind of double sticky tape in addition, and its structure comprises: a diaphragm, be interrupted gear, and be provided with a spacing every certain-length; Two gelatinous layers are located at the upper and lower surface of this diaphragm-operated respectively; One separate-type paper, bonding with this gelatinous layer of described diaphragm upper surface, this separate-type paper is positioned at diaphragm top, and this separate-type paper is continuous structure, and the length of described separate-type paper is greater than described diaphragm-operated length; Wherein, affiliated separate-type paper and diaphragm spacing corresponding position are provided with the branch broken string.The no viscose glue zone that the diaphragm spacing was produced during this double sticky tape used can make things convenient for separate-type paper to tear from diaphragm, and the broken string of the branch on separate-type paper and the diaphragm can make double sticky tape severing easily, when having solved known double sticky tape and using, need just adhesive tape to be cut into the inconvenience that suitable length is brought by scissors or blade.The double sticky tape of this patented technology, also have at present and make certain width by coiling, the reel shape belt carcass of size is installed on the product that uses in the applicator box body and releases in market sale, but the product of this patented technology is compared with the double sticky tape of top described technology, its adhesive-layer is made up of for three layers a membrane layer (commercially available is papery) and two gelatinous layers, though be installed in to have solved when using in the tape drum and drag glue wire drawing phenomenon, but its shortcoming is: the structure relative complex, cause the technological process of production complicated, consume man-hour, energy, material is many, cause production cost higher, and because the adhesive tape number of plies causes adhesive tape thickness thicker more, use its length that can adorn adhesive tape of onesize applicator box body more much smaller, thereby also increased packing of product cost than aforementioned double sticky tape.

The utility model content

Technical problem to be solved in the utility model is the deficiency that exists at prior art, and provide a kind of simple in structure, production cost is low, can be made into reel shape belt carcass and is installed in the applicator box body, draws at adhesive film during use not produce the double sticky tape that drags glue wire drawing phenomenon in the severing process.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of double sticky tape, comprise the off-style paper layer that the last adherent layer that is connected by upper and lower two surface-coated of ribbon matrix layer and its and following adherent layer are formed, upper surface coating at off-style paper layer is connected with adhesive-layer, it is characterized in that: described adhesive-layer is identical by thickness, and the independent pressure-sensitive adhesive film unit of continuous uniform arrangement is formed.The unitary width of described pressure-sensitive adhesive film is 0.5～8mm, and the spacing between each adjacent cells limit is 0.15～3mm.

Compared with prior art, advantage of the present utility model is:

1, compare by the double sticky tape that is coated on equably on the off-style paper layer continuously with the adhesive-layer of double sticky tape, because double sticky tape adhesive-layer glued membrane of the present utility model is that to be coated in the adhesive tape separate-type paper with the continuous uniform arrangement of separate unit form lip-deep, there is a determining deviation between each pressure-sensitive adhesive film unit adjacent edge, so, making belt carcass when adhesive tape is installed on the applicator box body, in the use when lifting from out paper or body surface on the tape drum head, just can easily the adhesive-layer glued membrane be drawn severing, overcome existing double sticky tape use draw in the severing process easily produce drag glue wire drawing phenomenon, guaranteed the carefully and neatly done and cleaning that adhesive film applies.

2, compare for the double sticky tape that the dots structure form is coated on the separate-type paper with the adhesive-layer of double sticky tape, double sticky tape of the present utility model has overcome point-like adhesive-layer glued membrane unit and has existed the gap more each other, being coated in actual use by the viscose glue area on sticking paper or the object unit area of being caused reduces, thereby causes the defect that bonding strength reduces between the sticky object.

3, compare by three layers of double sticky tape of forming of a membrane layer and two gelatinous layers with the adhesive-layer of double sticky tape, though all can overcome in using and drag glue wire drawing phenomenon, but the utility model adhesive tape adhesive-layer is made up of the individual layer pressure-sensitive adhesive film, it is simple that tool is produced coating processes, consume man-hour, energy, material be few, production cost is low, the characteristics that result of use is good.
