preparation example Construction

[0085] On the other hand, an embodiment of the present invention provides a method for preparing an adhesive tape that can be removed by 90°, comprising:

[0086] A solvent, an elastomer, a tackifying resin and an anti-aging agent are respectively added to the reaction vessel, and the mixture is stirred for a first specified time at a specified temperature and a first specified rotation speed to obtain a first resin mixture;

[0087] After the first resin mixture is cooled to room temperature, a leveling agent is added, and the mixture is stirred at a second designated rotation speed for a second designated period of time to obtain a second resin mixture;

[0088] adjusting the viscosity of the second resin mixture to a specified viscosity range to obtain the first glue, the second glue or the third glue;

[0089] Coat the first glue, the second glue or the third glue on the release material, after drying treatment, the obtained first glue layer 1, second glue layer 2 and thir...

Embodiment 1

[0099] The first glue and the third glue each independently include:

[0100] Toluene, 40 parts;

[0101] Ethyl acetate, 6 parts;

[0102] 1155, 6 copies;

[0103] 4202, 20 copies;

[0104] 3868, 17 copies;

[0105] P90, 3 servings;

[0106] ARIZONA TP2040, 5 servings;

[0107] 1020, 1 serving;

[0108] BHT (2,6-di-tert-butyl-4-methylphenol), 1 part;

[0109] BYK 300, 1 serving.

[0110] In this embodiment, the solvent includes toluene and ethyl acetate, and the elastomer includes 1155 and 4202, the tackifying resin includes 3868, P90, ARIZONATP2040 and 1020, the anti-aging agent is BHT, and the leveling agent is BYK300.

[0111] The preparation method of the first glue is as follows: toluene and ethyl acetate are prepared as a mixed solvent. Will 1155. Taiwan Rubber Add 4202 and BHT to the mixed solvent, turn on the heating and stir, keep the temperature of the mixed solution at 85°C, and make 1155 and 4202 dissolves completely. Then grad...

Embodiment 2

[0115] The first glue and the third glue each independently include:

[0116] Toluene, 16 parts;

[0117] Isobutanone, 32 servings;

[0118] 4114, 15 copies;

[0119] Guangdong Zhonghe Chemical SIS1501, 10 copies;

[0120] 105, 24 servings;

[0121] Arizona TP7042, 1 serving;

[0122] BHT, 1 serving;

[0123] BYK390, 1 serving.

[0124] In this embodiment, the solvent includes toluene and isobutyl ketone, and the elastomer includes 4114 and Guangdong Zhonghe Chemical Plastic SIS1501, the tackifying resin includes 105 and Arizona TP7042, the anti-aging agent is BHT, and the leveling agent is BYK390.

[0125] The preparation method of the first glue is as follows: toluene and isobutyl ketone are prepared into a mixed solvent. Will 4114, Guangdong Zhonghe Chemical Plastics SIS1501 and BHT are added to the mixed solvent, turn on the heating and stir, and keep the temperature of the mixed solution at 85 ℃, so that 4114 and SIS1501 dissolve completely. Then gra...

Abstract

The invention belongs to the technical field of pressure-sensitive adhesives, and in particular relates to a 90° removable adhesive tape, a preparation method thereof, and an electronic product. A 90° removable adhesive tape comprises a first adhesive layer, a second adhesive layer and a The third adhesive layer; the first adhesive layer and the third adhesive layer each independently include the following mass components: 18-28 parts of elastomer, 20-30 parts of tackifying resin; the second adhesive layer includes the following Quality components: 18-28 parts of elastomer and 15-23 parts of tackifying resin; wherein, the content of tackifying resin in the first adhesive layer is higher than that in the second adhesive layer. In the present invention, through the continuous and controllable distribution of viscosity and elasticity, the purpose of viscosity and 90° removal can be achieved at the same time, ensuring the stability of the 90° removable tape, and the first adhesive layer and the third adhesive layer have better Viscous, the second adhesive layer has better elasticity or strength, which improves the detachability of the tape, and is not easy to produce adhesive residue when the tape is removed.

Description

technical field [0001] The invention belongs to the technical field of pressure-sensitive adhesives, and in particular relates to a 90° removable adhesive tape, a preparation method thereof, and an electronic product. Background technique [0002] With the rapid development of the electronics industry, users in consumer electronics, home appliances and other industries are increasingly pursuing products that are thin and delicate in appearance, pursuing personalization and fresh experience, and the pace of product upgrading has also accelerated. , and even recycling have put forward higher requirements. In particular, batteries that pollute the environment must be disassembled without damage, and in order to achieve reliable performance during assembly, they must be permanently bonded. Under the current viscosity, small-angle removal is not only required by design. Contrary to the narrow space, it also represents the limitation of removal, which is not conducive to repair a...
