Problems solved by technology

However, the adhesive properties of the current double-sided tapes are all strong, and there is no optional type with different strengths on both sides.
This brings disadvantages to practical applications, such as pasting exquisite pictures on the wall, the wall adhesion performance is poor and strong glue is needed, but the strong glue also makes the picture paper be too sticky, it is difficult to be completely in the future Remove and replace or collect

Embodiment 6

[0037] Embodiment 6, a double-sided adhesive tape, differs from Embodiment 3 in that the tackifying resin is rosin resin.

Embodiment 7

[0038] Embodiment 7, a double-sided adhesive tape, differs from Embodiment 3 in that the tackifying resin is a 1:1 compound of rosin resin and petroleum hydrogenated resin.

Embodiment 8

[0039] Embodiment 8, a production method of double-sided adhesive tape, the components used are all the components in Embodiment 3, and the content and corresponding process steps are as follows:

[0040] S1, raw material preparation, preparing the base layer composed of finished release paper, polyester antistatic film layer and biaxially stretched colorless and transparent polyethylene terephthalate and polyimide;

[0041] At the same time, get 11 parts of epoxy resin adhesive, 0.1 part of coupling agent, 0.3 part of leveling agent, 0.2 part of defoamer, 0.5 part of accelerator, and 1 part of talcum powder to mix and heat fully to obtain The first ready-to-use product for preparing the first pressure-sensitive adhesive layer and the second pressure-sensitive adhesive layer;

[0042] At the same time, take 18 parts of acrylate, 16 parts of thermoplastic elastomer, 4 parts of microcrystalline wax, 12 parts of synthetic wax, 32 parts of tackifying resin, 5 parts of curing agent...

Abstract

The invention discloses a double-sided adhesive tape and a production method thereof. The double-sided adhesive tape comprises release paper, a first pressure-sensitive adhesive layer, a base layer and a second pressure-sensitive adhesive layer which are sequentially attached, a viscosity reduction layer is further arranged between the release paper and the first pressure-sensitive adhesive layer,and the first pressure-sensitive adhesive layer and the second pressure-sensitive adhesive layer comprise an epoxy resin adhesive, a coupling agent, a leveling agent, a defoaming agent, an accelerantand talcum powder; and the viscosity reduction layer comprises an acrylate, a thermoplastic elastomer, microcrystalline wax, synthetic wax, tackifying resin and a modifying aid, and the peel strengthof the viscosity reduction layer is 70%-80% of the peel strength of the first pressure-sensitive adhesive layer and the second pressure-sensitive adhesive layer. Through the arrangement, the viscosity reduction layer is arranged between the release paper and the first pressure-sensitive adhesive layer, so that the peel strengths of two sides of the double-sided adhesive tape are different, the double-sided adhesive tape can adapt to different use occasions, and meanwhile, the viscosity reduction layer can peel the first pressure-sensitive adhesive layer, so that the peel strength of the surface is improved, and the application range is further expanded.

Description

technical field [0001] The invention relates to the field of stationery, in particular to a double-sided adhesive tape and a production method thereof. Background technique [0002] Double-sided adhesive tape is a roll-shaped adhesive tape made of paper, cloth, and plastic film as the base material, and then uniformly coated with elastomer-type pressure-sensitive adhesive or resin-type pressure-sensitive adhesive on the above-mentioned base material. , adhesive, and release paper are composed of three parts. Double-sided tape is widely used in leather, stickers, stationery, office, electronics, automobile and other industries. With the development of economy, double-sided tape is used more and more widely, and the quality of double-sided tape also needs to be improved. [0003] Double-sided adhesive tape brings convenience to the bonding and attaching of various objects because of its double-sided adhesive. However, this ease of use does not take into account the need to s...
