Description

Non-contact IC card with pearl effect Technical Field The utility model relates to the field of manufacturing of non-contact IC cards, in particular to a non-contact IC card capable of achieving a pearl effect. Background With the development and progress of technology, more and more new materials are applied to various industries, for example, in the process of manufacturing cards such as bank cards and membership cards, special effects are usually added on the surface of the card to improve the visual effect and the aesthetic degree. Firstly, the pearl pattern is printed on the surface of the card, then a layer of adhesive is attached, and then the card with the pearl pattern and the adhesive and the outermost layer material are pressed into a whole at high temperature. In practical production, since the card-type product is formed by high-temperature pressing of a multi-layer structure, after printing a layer of pearlescent ink, the stripping value of the layer can be influenced. In addition, as one layer of ink is added, the lamination temperature is not uniformly conducted in the card body, the card body is easy to deform, and even the card body part is excessively melted, so that irregular 'flowing edges' are generated. In view of this, the present utility model has been made. Disclosure of utility model The utility model aims to provide a non-contact IC card capable of realizing a pearl effect, which solves the problem that the pearl non-contact IC card is easy to peel off due to a pearl layer in the prior art. The utility model discloses a non-contact IC card with a pearl effect, which comprises a base material, a pearl layer and an outermost layer, wherein the pearl layer is arranged between the base material and the outermost layer, and the pearl layer is formed by mixing pearl powder and a water-based adhesive and then printing. In some embodiments, the inner side of the outermost layer of the non-contact IC card is provided with a pearl pattern. In some embodiments, the pearlescent pattern is formed by placing a water-based adhesive in a container, taking pearlescent powder, pouring the pearlescent powder into oil, sufficiently stirring the mixture uniformly, printing the prepared water-based adhesive on the inner side of the outermost layer of the non-contact IC card, and finally pressing the non-contact IC card at a high temperature. In some embodiments, the pearlescent layer is selected from the group consisting of a pearlescent powder particle size of 300-500 mesh. Pouring the water-based adhesive into oil according to the proportion of powder= (200-400): 1, and fully and uniformly stirring the mixture by using a stirring device; The step of printing the prepared water-based adhesive on the inner side of the outermost layer of the non-contact IC card and finally pressing the water-based adhesive at high temperature to form the non-contact IC card comprises the steps of selecting a screen printing plate with 150-350 meshes, silk-printing the prepared water-based adhesive on the inner side of the outermost layer of the non-contact IC card, then airing, transferring to a subsequent process after the water-based adhesive is dried thoroughly, and finally pressing the water-based adhesive at high temperature to form the non-contact IC card. In some embodiments, the reason why the 300-500 mesh pearlescent particles are preferable is that the effect of pearlescent stealth can be more exhibited. When the pearlescent particles are large, the particles are too obvious and are easy to shade the pattern, and the effect of the pearlescent effect cannot be reflected. When the particles are too small, the pearlescent effect is too weak, difficult to observe, and the effect is poor. In addition, the size of the pearlescent particles selected by the utility model is also combined with the characteristic of screen printing, and even if the product is matched with a common screen printing screen, the obtained product can also show good pearlescent effect. The ratio of water-based adhesive to powder= (200-400): 1 is preferred to make the pearlescent effect better. If too much pearl powder is blended, the effect of brightness and darkness of the card surface is affected, and if too little pearl powder is blended, the pearl effect cannot be exhibited. The screen printing plate with 150-350 meshes is preferable for screen printing the mixture, so that the screen printing plate is convenient for meeting daily production requirements, and can also exhibit better printing effect. In some embodiments, the outermost layer of the contactless IC card is a transparent protective layer. In some embodiments, the pearlescent powder is a diamond-flash silver powder. In some embodiments, the pearlescent powder is a metal oxide-based pearlescent powder or a mica-based pearlescent powder. In some embodiments, the pearlescent powder particle size is preferably 350-450 mesh. In some embodiments, the pearlescent powder particle size
