Embodiment 1
[0014] Such as figure 1 As shown, the vamp sticker of the present invention includes a flower layer 1 and an adhesive layer 2, the adhesive layer 2 is a flat sealed bag, and the sealed bag is encapsulated with α-cyanoacrylate ethyl ester paste adhesive, and the thickness of the adhesive layer 2 is 0.1-5mm, pasted below the flower layer 1.
[0015] The preparation process of the vamp sticker is as follows: First, heat-stitch the three sides of the polyethylene film, leaving one side open to form a quasi-sealed bag; then paste the quasi-sealed bag on the flower layer 1 with super glue, or use sewing to repair it. The quasi-sealed bag is fixed together with the flower layer 1 . Open the opening of the quasi-sealed bag, pour α-cyanoacrylate ethyl ester paste adhesive into the quasi-sealed bag, exhaust the air and flatten it, so that the thickness of the quasi-sealed bag filled with adhesive is between 0.1-5mm, and then put The opening sealing of the quasi-sealed bag promptly mak...
Embodiment 2
[0019] The preparation method of the α-cyanoacrylate ethyl ester paste adhesive used in the present invention is as follows: the proportion of each component is 88% of α-cyanoacrylate ethyl, 5.5% of ethylene glycol ether, and 6.5% of fumed white carbon black. %, sulfur dioxide 42mg / kg, 2,6-di-tert-butyl-4-methylphenol 900mg / kg, and quartz sand 15g / kg are mixed together to obtain a paste adhesive with good cohesiveness. The adhesive can be solidified in 1min.
