Detailed Description
The present invention will be described in further detail with reference to the following embodiments and the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.
Example one
The splicing type square adhesive shown in fig. 1 comprises two parallel first frames 10 and two parallel second frames 20, wherein the first frames are perpendicular to the second frames, and the end parts of the first frames are over against the inner side walls of the second frames. Referring to fig. 2, the first frame includes the first release layer 11 that is located the top layer and the first double-sided adhesive layer 12 that is located the bottom, and the second frame includes the second release layer 21 that is located the top layer and the second double-sided adhesive layer 22 that is located the bottom, and the both ends of the non-release surface of the first release layer are respectively laminated with the protection film 30 of having the PE or PET material of pasting, and the tip that the protection film corresponds second frame 20 extends forward and pastes to the bottom of double-sided adhesive layer two 22. The length of the protective film which is attached to the upper part of the first release layer is 5mm-10mm.
The manufacturing process of the square glue shown in figure 1 is as follows:
s1, two parallel first frames with the distance of 5mm-10mm are used as a first basic part 40, and arrays are attached to a bottom plate 50 at set steps;
s2, attaching a protective film to each first frame;
s3, respectively attaching a second basic piece 60 to two sides of the first basic piece along the length direction of the bottom plate, and pressing the protective film on the bottom plate by the second basic pieces;
s4, die-cutting the shape of the first frame on the second basic piece and then discharging waste;
and S5, cutting the bottom plate along the space between the two first frames in the first basic part to obtain the square glue.
Even if the first frame and the second frame are overlapped in the production process, the first double-sided adhesive layer and the second double-sided adhesive layer are isolated through the protective film, so that the adhesion of the two double-sided adhesives is avoided, the phenomena of adhesive pulling and adhesive overflowing cannot be caused by subsequent waste discharge, and the production yield of the square adhesive is improved to 99%.
The second base part needs to flatly press the protective film on the bottom plate, in order to avoid wrinkling of the protective film, the through hole can be formed in the position, corresponding to the protective film, of the bottom plate, the protective film is tightly adsorbed on the bottom plate by adopting a negative pressure process in the production process, and wrinkling of the protective film can be effectively prevented.
Preferably, the peel force of the protective film is 10g/mm to 20g/mm. Specifically, the peel force of the protective film is 10g/mm, 11g/mm, 12g/mm, 13g/mm, 14g/mm, 15g/mm, 16g/mm, 17g/mm, 18g/mm, 19g/mm, 20g/mm.
Preferably, the thickness of the protective film is 0.05mm to 0.08mm. Specifically, the thickness of the protective film is 0.05mm, 0.06mm, 0.07mm, 0.08mm.
Preferably, the width of the protective film is 1mm-2mm larger than the width of the first double-sided adhesive layer, and the protective films which are arranged in the width direction can cover the first double-sided adhesive layer in all directions, so that the second double-sided adhesive layer is prevented from contacting the first double-sided adhesive layer.
Preferably, the length of the protective film adhered to the lower part of the second double-sided adhesive layer is 5mm-10mm, and the specific length is as follows: 5mm, 6mm, 7mm, 8mm, 9mm, 10mm. The setting of this length is according to the width design of two-sided glue film two, and suitable length both can prevent that the protection film from upwarping before the laminating of second basis piece, also makes things convenient for tearing of protection film to remove.
Example two
The difference between the present embodiment and the first embodiment is:
referring to fig. 4, a protective film 30 is attached to the non-release surface of the release layer i, and two ends of the protective film respectively extend forward and are attached to the bottom of the corresponding double-sided adhesive layer ii 22.
The two protective films are used in one adhesive for the square, so that the adhesive surfaces of the four splicing parts are isolated, and the production and the manufacture of the adhesive for the square are facilitated.
Preferably, a handle 31 is provided at the middle portion of the protective film to protrude outward, so that the protective film can be easily removed by holding the handle when removing the protective film. The handle portion dislocation set of protection film both sides so can avoid adjacent mouth word to glue the protection film in and overlap, the production is glued to the mouth word of being convenient for.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
