Description

Technical Field

[0001] The utility model relates to the technical field of double-sided film tapes, in particular to a polyimide heat-resistant double-sided film tape. Background Art

[0002] Double-sided tape is a roll of adhesive tape made of paper, cloth, or plastic film as the base material, and an elastomeric pressure-sensitive adhesive or resin-type pressure-sensitive adhesive is evenly coated on the above-mentioned base material. It consists of three parts: base material, adhesive, and release paper (film) or silicone oil paper.

[0003] Application number CN201821988950.X discloses a high-temperature resistant tape, including a tape body and other structures. The high-temperature resistant tape is provided with a high-temperature resistant tape layer and a polyimide film layer on the surface of the base material layer. The two cooperate to make the tape body have excellent high-temperature resistance. The wear-resistant layer is located on the surface of the tape body to make the tape body more durable. At the same time, the easy-tear line facilitates quick tearing when using the tape body, thereby improving the efficiency of tape use. The base material of the polyimide film makes the tape body have good high-temperature resistance. When the application is used, the setting of the easy-tear line helps to tear it quickly, but it is easy to tear, which then causes waste of resources and inconvenience in use. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A polyimide heat-resistant double-sided film tape includes a bonding mechanism, which includes a cylinder and a tape body sleeved on the outside of the cylinder. The tape body is composed of adhesive, outer oil paper and two inner oil papers, the outer oil paper is bonded to the outside of the adhesive, and the two inner oil papers are bonded to the inside of the adhesive.

[0007] By adopting the above technical solution, since there is a gap between the two inner oil papers, the adhesive that is rolled up layer by layer has the opportunity to adhere to the outer wall of the outer oil paper, thereby achieving stable winding of the tape. Then, when the movable end of the tape body breaks, the operator can easily lift up the broken position through the position of the inner oil paper, assisting the operator to quickly find the broken position and improving the comfort of use.

[0008] In a preferred example, the present invention can be further configured as follows: the adhesive, outer oil paper, and inner oil paper are of equal length, and the two inner oil papers are laterally symmetrical about the horizontal center plane of the adhesive.

[0009] In a preferred example, the present invention can be further configured as follows: the outer oil paper and the inner oil paper have the same thickness.

[0010] In a preferred example, the present invention can be further configured as follows: a plurality of notches are provided on the top and the bottom of the cylinder, and the plurality of notches are equidistant and annularly enclosed to form two circles.

[0011] In a preferred example, the present invention can be further configured as follows: two annular disks are sleeved on the outer side of the cylinder, and the two annular disks are respectively attached to the top and bottom of the tape body.

[0012] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0013] In the present invention, since there is a gap between the two inner oil papers, the adhesive rolled up layer by layer has a chance to adhere to the outer wall of the outer oil paper, thereby achieving stable winding of the tape. Then, when the movable end of the tape body breaks, the operator can easily lift up the broken position through the position of the inner oil paper, assisting the operator to quickly find the broken position and improving the comfort of use.

[0022] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0023] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0024] The following describes a polyimide heat-resistant double-sided film tape provided by some embodiments of the present invention in conjunction with the accompanying drawings.

[0025] Example 1:

[0026] Combine Figure 1-4 As shown, the present invention provides a polyimide heat-resistant double-sided film tape, comprising a sticking mechanism 100, wherein the sticking mechanism 100 comprises a cylinder 110 and a tape body 120 sleeved on the outside of the cylinder 110;

[0027] The tape body 120 is composed of an adhesive 121 , an outer oil paper 122 and two inner oil papers 123 . The outer oil paper 122 is adhered to the outer side of the adhesive 121 , and the two inner oil papers 123 are adhered to the inner side of the adhesive 121 .

[0028] Furthermore, the adhesive 121, outer oil paper 122, and inner oil paper 123 are of equal length, and the two inner oil papers 123 are laterally symmetrical about the horizontal center plane of the adhesive 121. With this size design, the tape body 120 will not be rolled up with any structural length or shortness, thereby ensuring the aesthetics of the product.

[0029] Furthermore, the outer oil paper 122 and the inner oil paper 123 are of equal thickness, and the same thickness design makes the appearance of the product more beautiful.

[0030] Example 2:

[0031] Combine Figure 1 、 2 As shown in FIG4 , based on the first embodiment, a plurality of notches 200 are provided on the top and bottom of the cylinder 110. The plurality of notches 200 are equally spaced and arranged in a circular shape to form two circles. The provision of the notches 200 can reduce the materials used in manufacturing the cylinder 110 and reduce its manufacturing cost.

[0032] Example 3:

[0033] Combine Figure 1 and Figure 4 As shown, in the above embodiment, two annular disks 300 are sleeved on the outside of the cylinder 110, and the two annular disks 300 are respectively attached to the top and bottom of the tape body 120. The annular disks 300 can be set to limit the tape body 120 from both sides, so that the tape body 120 can be stably stretched.

[0034] The working principle and usage process of the present invention are as follows: when the device is put into actual use, since there is a gap between the two inner oil papers 123, the adhesive 121 that is rolled up layer by layer has the opportunity to adhere to the outer wall of the outer oil paper 122, thereby achieving stable rolling of the tape. Then, when the movable end of the tape body 120 is broken, the operator can easily lift up the broken position through the position of the inner oil paper 123, assisting the operator to quickly find the broken position and improving the comfort of use.

[0035] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and purpose of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
