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...
