Description

Technical Field

[0001] The utility model belongs to the technical field of double-sided tapes, and particularly relates to a flame-retardant PET double-sided tape. Background Art

[0002] A double-sided tape is a roll-shaped adhesive tape made of paper, cloth, plastic film, elastomeric pressure-sensitive adhesive or resin-based pressure-sensitive adhesive. It can be classified into grid double-sided tapes, reinforced double-sided tapes, Rubber double-sided tapes, high-temperature double-sided tapes, non-woven double-sided tapes, residue-free double-sided tapes, cotton paper double-sided tapes, double-sided glass cloth tapes, PET double-sided tapes, foam double-sided tapes, etc., and is applied in the production processes of various industries.

[0003] The traditional double-sided tape consists of a paper tube and a double-sided tape body, with a relatively simple structure. The following deficiencies exist in actual use:

[0004] 1. The double-sided tape is easily deformed by external forces and worn, lacking a protection mechanism.

[0005] 2. The flame retardancy of the double-sided tape is poor. When the temperature of the carrier is relatively high, the double-sided tape is easily burned.

[0006] Therefore, we propose a flame-retardant PET double-sided tape. Content of the Utility Model

[0007] The purpose of the utility model is to solve the deficiencies in the prior art that the double-sided tape is easily deformed by external forces and worn, lacking a protection mechanism, and the flame retardancy of the double-sided tape is poor. When the temperature of the carrier is relatively high, the double-sided tape is easily burned, and a flame-retardant PET double-sided tape is proposed.

[0008] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0009] A flame-retardant PET double-sided tape, comprising:

[0010] A base and a top cover, the base and the top cover are threadedly connected, and the materials of the base and the top cover are both aluminum alloy;

[0011] A paper tube, the paper tube is arranged inside the base, and a double-sided tape body is arranged on the outer wall of the paper tube. The double-sided tape body includes a release paper layer, a first acrylic adhesive layer, a PET flame-retardant layer, and a second acrylic adhesive layer, and the release paper layer, the first acrylic adhesive layer, the PET flame-retardant layer, and the second acrylic adhesive layer are sequentially arranged in order;

[0012] A cutting mechanism, the cutting mechanism is arranged on the inner wall of the top cover, and the cutting mechanism is used for cutting the double-sided tape body.

[0013] In a possible design, the cutting mechanism includes a U-shaped fixed block which is fixedly penetrated through the circumferential inner wall of the top cover. An adjusting block is slidably connected inside the fixed block, and a blade is fixedly provided at one end of the adjusting block, facilitating people to cut the double-sided tape main body.

[0014] In a possible design, annular sealing grooves are provided on the inner walls of both the base and the top cover, and sealing rings are provided in both of the two sealing grooves to prevent dust from entering the base.

[0015] In a possible design, positioning blocks are provided on the inner wall of the paper tube, and positioning grooves adapted to the positioning blocks are formed on the inner wall of the base to position the paper tube.

[0016] In a possible design, a rubber block is adhesively bonded to the inner wall of the top of the top cover to limit the paper tube.

[0017] In a possible design, a plurality of anti-slip grooves are provided on the outer wall of the top cover to facilitate people to rotate the top cover.

[0018] In this application, when using the double-sided tape, rotate the top cover to separate it from the base, then take out the double-sided tape, then move the adjusting block to push the blade so that the blade extends out of the fixed block, then use the blade to cut off an appropriate length of the double-sided tape main body, then stick the double-sided tape main body on the carrier and tear off the release paper layer, then connect the object to be fixed with the double-sided tape, and then retract the blade into the fixed block and put the double-sided tape back into the base.

[0019] In this utility model, for the flame-retardant PET double-sided tape, through the settings of the base and the top cover, protection can be provided for the double-sided tape to prevent the double-sided tape from being deformed by external forces and damaged, and at the same time prevent dust from adhering to the surface of the double-sided tape;

[0020] In this utility model, for the flame-retardant PET double-sided tape, through the settings of structures such as the release paper layer and the PET flame-retardant layer, the flame retardancy of the double-sided tape can be improved to prevent the double-sided tape from being burned when the temperature of the carrier is relatively high;

[0021] In this utility model, for the flame-retardant PET double-sided tape, through the settings of the fixed block, the adjusting block and the blade, when using the double-sided tape, people can directly cut the double-sided tape with the blade without the need to prepare additional cutting tools, which provides convenience for people;

[0022] In this utility model, protection can be provided for the double-sided tape to prevent the double-sided tape from being deformed by external forces and damaged, the flame retardancy of the double-sided tape can be improved to prevent the double-sided tape from being burned by high temperature, and it is also convenient for people to cut the double-sided tape, which provides convenience for people.
