Embodiment Construction
[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0025] like figure 1 As shown, a flexible glass explosion-proof film, from top to bottom, sequentially includes a first PET layer 1, a first silicone pressure-sensitive silicone layer 2, a polyurethane acrylic coating layer 3, a PC / PMMA substrate 4, an acrylic adhesive layer 5, The second PET6 layer, the second silicone pressure-sensitive silicone layer 7 and the third PET layer 8 .
[0026] Wherein, the thicknesses of the first PET layer 1, the second PET6 layer and the third PET layer 8 are respectively 0.025-0.075mm. The PET layer is used to protect the application layer after coating the silicone pressure sensitive adhesive.
[0027] Wherein, the thickness of the first silicone pressure-sensitive silicone layer 2 is 0.05-0.015mm, so as to protect the polyurethane acrylic coating layer 3 from being scratched before use; the thickness of the second silico...
