| description | The invention discloses an invisible anti-counterfeiting seal and a preparation method thereof. The preparation method includes the following steps that polydimethyl siloxane and a curing agent are mixed evenly, bubble-removing is carried out, mixing liquid is taken out to be flatly laid on a glass board after bubbles disappear completely, secondary bubble-removing is carried out, the mixing liquid is poured into a mold to be subjected to curing forming, and a patch is obtained; the patch is cleaned and blow-dried, and subjected to oxygen plasma treatment, and then the patch is soaked, washedand blow-dried; and a mask is printed on the surface of the polydimethyl siloxane, laser ablation is carried out, the mask is placed in a nitrogen atmosphere, mixing gas is fed, heating is carried out, and a seal is taken out after cooling, and the seal is cleaned to obtain the invisible anti-counterfeiting seal. The invention further includes the invisible anti-counterfeiting seal prepared by themethod. The seal achieves |
