Embodiment
[0034] Such as figure 1 As shown, the above-mentioned multi-metal vapor phase anti-rust pressure-sensitive adhesive sponge comprises an upper layer 1, a middle layer 2, and a lower layer 3, the middle layer 2 is a sponge layer, the upper layer 1 is a gas-phase anti-rust hot-melt pressure-sensitive adhesive layer, and the lower layer 3 is a gas phase Anti-rust layer.
[0035] The above-mentioned sponge layer is polyethylene sponge, the foaming rate is 20-30 times, the thickness is 0.5-100mm, and different colors can be selected.
[0036] The above-mentioned hot-melt pressure-sensitive adhesive layer is prepared from the following components by weight ratio:
[0037] Styrene, butadiene or isoprene block copolymer 0.30-0.40
[0038] White oil or naphthenic oil 0.20-0.30
[0039] Lightened rosin or terpene resin 0.10-0.20
[0040] Antioxidant 0.005-0.01
[0041] Cyclohexylamine Benzoate 0.08-0.20
[0042] Ammonium benzoate 0.06-0.15
[0043] Benzotriazole 0.03-0.08
