Problems solved by technology

The former needs to wrap each tube core with foam, although the effect is good, but it is time-consuming and wasteful; the latter needs to slot on the tube core. For coils of different thicknesses, the thickness of the slot needs to be adjusted, otherwise it will not meet expectations Effect, the cost of slotting is high, the difficulty is high, and the versatility is not strong

Embodiment 1

[0038] see figure 1 , a foam tape 7, including an easy-adhesive layer 1, a foam layer 2, a first pressure-sensitive adhesive layer 3, a flexible reinforcing layer 4, a second pressure-sensitive adhesive layer 5, and a release material layer 6 arranged in sequence.

[0039] The material of the easy-bonding layer 1 is PU primer M-T-18, and the thickness of the easy-bonding layer 1 is 0.005mm, which can increase the adhesion of the foam surface.

[0040] The foam layer 2 is PU foam, which is made of polyurethane resin through the foaming process on the release material layer 6, and the foaming density is 200kg / m 3 , the thickness of the foam layer 2 is 0.8mm.

[0041] The first pressure-sensitive adhesive layer 3 and the second pressure-sensitive adhesive layer 5 are formed by coating the peelable acrylate adhesive on the release material layer 6. The thickness of the first pressure-sensitive adhesive layer 3 is 0.06 mm, and the thickness of the first pressure-sensitive adhesive...

Abstract

The invention belongs to the technical field of winding of coils, and particularly relates to a foam adhesive tape as well as a manufacturing method and application thereof. The foam adhesive tape comprises an easy adhering layer, a foam layer, a first pressure-sensitive layer, a smooth reinforcing layer, a second pressure-sensitive layer and a stripping material layer which are sequentially connected, wherein the foam layer is prepared from any of PU (polyurethane) or EVA (ethylene vinyl acetate); the smooth reinforcing layer is prepared from a TPU (thermoplastic polyurethane) adhesive film or a rubber film. When the foam adhesive tape is applied into the core winding of the films, the section difference caused by film winding can be reduced, the waste of the film material is reduced, andthe rate of finished product is increased.

Description

technical field [0001] The invention belongs to the technical field of coil winding, and in particular relates to a foam tape and a manufacturing method and application thereof. Background technique [0002] During the core winding operation of film materials, when the material is wound with the tube core, the height difference caused by the thickness of the material itself and the surface of the tube core, that is, the winding step difference. The thicker the material is, the more obvious the step difference is. Generally, it needs to be reeled for hundreds of meters, and the step difference can be compensated by the thickness deviation of the material itself and the influence of the winding tension. The horizontal end print caused by the level difference will seriously affect the appearance of the material. [0003] At present, in order to solve the problem of winding step difference on the market, the tube core is usually transformed. For example, the tube core is wrappe...
