Detailed Description

The technical solutions of the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings, and it is to be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without any creative effort, are within the protection scope of the present invention.

The embodiment of the utility model provides a foam adhesive tape.

Embodiment one, refer to fig. 1 and 2, a bubble cotton adhesive tape, including bubble cotton colloid 1, from type paper tape 2 and paper reel 3, bubble cotton colloid 1 is including bubble cotton base plate 4, reinforcing layer 5 and waterproof layer 6, waterproof layer 6 sets up in the inside of bubble cotton base plate 4, bubble cotton base plate 4 divide into first base plate layer 7 and second base plate layer 8, waterproof layer 6 wears to establish in the gap between first base plate layer 7 and the second base plate layer 8, bubble cotton base plate can adopt PE foaming, EVA foaming, PU foaming etc. it has the membrane material to adhere to on the bubble cotton base plate, the membrane material can select for use PET, PVC, PI, PEI etc.

Referring to fig. 2, the both sides of bubble cotton colloid 1 all are provided with adhesive coating 9, adhesive coating 9 sets up on strengthening layer 5, adopt the rubber gluing agent on the adhesive coating 9, strengthening layer 5 is fixed with bubble cotton base plate 4 through waterborne heat activation polyurethane adhesive, from type paper tape 2 cover on the adhesive coating 9 that is provided with the rubber gluing agent on strengthening layer 5, from type paper tape 2 through the rubber gluing agent adhere to on strengthening layer 5, it winds on the paper fiber container to adhere to bubble cotton colloid 1 from type paper tape 2, strengthening layer 5 adopts the TPU material.

Referring to fig. 1 and 3, a parting line 10 is arranged on a release paper tape 2, the parting line 10 extends along the length direction of the release paper tape 2, the distance between two adjacent parting lines 10 is the same, the parting line 10 is formed by cutting with a blade, the parting line 10 is composed of a plurality of parting holes 11, and round paper sheets 12 are covered in the parting holes 11. The round paper sheet 12 is a release paper sheet formed in the dividing hole 11 when the cutting hole 11 is formed by cutting with the blade, and the round paper sheet 12 is connected with the release paper tape 2. The two adjacent dividing lines 10 have the same pitch.

In the second embodiment, the difference is that the distance between two adjacent dividing lines 10 is different, so that the foam adhesive tape can be attached to two or more attaching surfaces with angles.

Third embodiment, referring to fig. 4, the difference is that the dividing line 10 is a separation slit 13 formed by knife cutting.

In the fourth embodiment, referring to fig. 5, the difference is that sewing threads 14 are provided on both sides of the foam rubber 1, the sewing threads 14 penetrate both ends of the first base layer board and the second base layer board, a plurality of sewing threads 14 extend in the longitudinal direction of the foam rubber 1, the sewing threads 14 are formed in an X shape by the sewing method of the sewing threads 14, and the sewing threads 14 are used for enhancing the stability of the foam rubber 1.

When needing large tracts of land cover to laminate on two faces that have the angle, take the foam cotton adhesive tape the same with the length of the face that needs the laminating, the face that the clearance needs the laminating tears off the segregation paper tape of a cut-off line 10 one side, the face that will expose is laminated with one of them face that needs the laminating, compress tightly the face of strengthening layer 5 and needs the laminating, wait for 24-48 hours the viscidity of strengthening layer 5 and reach the biggest effect, tear off cut-off line 10 opposite side this moment from type paper tape 2, the face that will expose here and another face laminating that needs the laminating. Other release paper tapes 2 can be torn off after the viscosity of the reinforcing layer 5 reaches the maximum effect, objects needing to be bonded and fixed are placed and fixed, or other release paper tapes 2 are not torn off, and the foam adhesive tape is only used as a damping layer or a waterproof layer 6. The arrangement of the round paper sheets 12 prevents the situation that the bonding effect of the foam adhesive tape is affected due to the fact that the part of the reinforcing layer 5 exposed outside is stained with dust when the foam adhesive tape is not used for a long time, the number of the dividing lines 10 and the distance between the dividing lines are the same or different, and the foam adhesive tape can be more suitable for different bonding environments due to the arrangement of the number of the dividing lines 10 and the distance between the dividing lines. The sewing thread 14 is arranged to fix the first substrate layer 7 and the second substrate layer 8 more firmly, so that the stability of the foam adhesive tape can be enhanced.

The reinforcing layer is made of TPU material with high elongation and high breaking strength, and has excellent removability and reworkability when the product is required to be disassembled and repaired after being made into the foam double-sided adhesive tape, so that the operation of workers is greatly facilitated; meanwhile, the reinforcing layer and the foaming layer are bonded by a heat-activated polyurethane adhesive, so that the foam foaming layer and the reinforcing layer have excellent adhesion, the risk of separation of the reinforcing layer and the foaming layer under high-temperature and high-humidity conditions after the foam is made into the adhesive tape is avoided, and the quality of the foam adhesive tape is improved.
