Problems solved by technology

[0004] In view of the above problems, the purpose of the present invention is to overcome the insufficient adhesion between the glue and the substrate film in the prior art that has easy-to-pull and removable adhesive tapes on the base material, and at the same time, the adhesive strength of the adhesive tape itself is not high, and the adhesion is not strong when used. At the same time, it is prone to partial fracture and cannot be completely removed when stretched and removed

[0025] The rubber-type glue used to prepare the TPU easy-to-pull removable tape contains the following raw materials in parts by weight: 150 parts of styrene-butadiene rubber, 130 parts of Ganzhou Taipu Chemical T115 terpene resin, 270 parts of toluene, 0.6 part of adhesion promoter ADDID900, color 7 parts of slurry; first dissolve the tackifying resin with toluene, then add styrene-butadiene rubber, adhesion promoter, and color paste in turn, and get the glue after stirring evenly; adjust the coating thickness, and apply the glue on the release paper or release paper On the molded film, drying, and bonding the TPU substrate to obtain a TPU substrate with a thickness of 120 μm and a removable double-sided adhesive tape. During the test of the obtained tape on the SUS steel plate, when the peeling force reached 4022 gf / inch, there was no separation and residual glue on the tape, which reflected the excellent adhesion between the TPU substrate and the tape.

[0028] The rubber-type glue used to prepare the TPU easy-to-pull removable tape contains the following raw materials in parts by weight: 120 parts of styrene-butadiene rubber, 130 parts of Arakawa chemical GB125 rosin resin, 300 parts of toluene, 4 parts of adhesion promoter ADDID901, and 8 parts of color paste ;Use toluene to dissolve the tackifying resin first, then add styrene-butadiene rubber, adhesion promoter, and color paste in turn, and mix well to obtain glue; adjust the coating thickness, and coat the glue on the release paper or film , dried, and bonded to the TPU substrate to obtain a TPU substrate with a thickness of 150 μm and a removable double-sided adhesive tape. During the test of the obtained tape on the SUS steel plate, when the peeling force reached 4114 gf / inch, no separation and residual glue was found in the tape, which reflected the excellent adhesion between the TPU substrate and the tape.

[0031] The rubber-type glue for preparing the TPU easy-to-pull removable adhesive tape includes the following raw materials in parts by weight: 100 parts of synthetic natural rubber, 120 parts of Arakawa chemical GB125 rosin resin, 300 parts of toluene, 3 parts of adhesion promoter ADDID901, and 8 parts of color paste ;Use toluene to dissolve the tackifying resin first, then add natural synthetic rubber, adhesion promoter, and color paste in turn, and mix well to obtain glue; adjust the coating thickness, and apply the glue on the release paper or release film , dried, and bonded to the TPU substrate to obtain a TPU substrate with a thickness of 200 μm and a removable double-sided adhesive tape. During the test of the obtained tape on the SUS steel plate, when the peeling force reached 4231 gf / inch, there was no separation and residual glue on the tape, which reflected the excellent adhesion between the TPU substrate and the tape.

Abstract

The invention discloses an easy-to-pull removable double-sided adhesive tape of a TPU base material. The adhesive tape comprises the following components in parts by mass: 80-150 parts of rubber raw materials, 75-130 parts of tackifying resins, 100-350 parts of toluene, 0.1-5 parts of adhesion promoters and 5-15 parts of color paste. The adhesive tape of the TPU base material is a double-sided fixing adhesive tape with higher adhesive strength, can be used after stripping release paper or laminating release films when in use, can be removed only by stretching the adhesive tape when needed, andcan bring great convenience to workers in the maintenance of electronic components.

Description

technical field [0001] The invention belongs to the field of double-sided adhesive fixing tapes, and in particular relates to a TPU substrate easy-to-pull removable double-sided adhesive fixing tape. Background technique [0002] Double-sided tape is a tape product that connects different objects together by bonding. It is widely used in the bonding and fixing of electronic products, printed matter, handicrafts, metal, glass, toys and other materials. Double-sided tape products play different roles in different industries. With the increasing popularity of modern electronic products such as smartphones and tablet computers, double-sided tape plays an irreplaceable role in the fixing of electronic components and other equipment. However, many electronic components are difficult to disassemble after being fixed by tape. When the staff need to rework due to other reasons during the product assembly process, the product is only used as a temporary fix during the product process...
