Description

Technical Field

[0002] Mirror cardboard is glass cardboard, also known as cast-coated paper. Low-quantity ones are also called high-gloss copper plates, or mirror copper plates. Its production method is different from that of general coated paper. The painted paper is first placed in a drying box, and then electroplated under semi-dry conditions on a large-diameter oven similar to a mirror. Then, the surface of the cylinder is replicated during drying to make its surface smooth. Mirror cardboard is mostly used in cigarette packaging, lamination, medicine, cosmetics packaging and other fields.

[0003] The existing mirror-finished cardboard mainly consists of a base layer, a micro-coating layer, a polyethylene coating layer, a metal layer and a waterproof layer, wherein the base layer is one of offset paper, coated paper, white cardboard, glass cardboard or synthetic paper, a micro-coating layer is provided at the bottom of the base layer, and the micro-coating layer is obtained by micro-coating liquid on the surface of the base layer, and a polyethylene coating layer is provided on the upper surface and the bottom surface of the micro-coating layer, respectively, an upper polyethylene coating layer and a lower polyethylene coating layer, and a metal layer is provided at the bottom of the micro-coating layer, and a waterproof layer is connected to the bottom of the metal layer. The gloss and brightness of the mirror surface are increased by arranging a metal plating layer at the bottom, and the waterproof layer is provided at the bottom of the metal layer to dry the metal layer to prevent it from being oxidized by moisture, thereby providing a certain degree of moisture-proof protection for the paper; since the multi-layer material boards used to construct the cardboard are fixedly bonded and the base color is fixed, the mirror refraction effect of the cardboard is single, that is, it presents a single color tone, lacks interactivity with users, and is prone to aesthetic fatigue;

[0004] In addition, in order to improve its moisture resistance and thus increase the service life of the existing mirror cardboard, the waterproof layer is mostly filled with solid water absorbents, such as solid NaOH, CaO, soda lime, solid CaCl2, solid MgCl2, etc. However, with the increase of usage time and water absorption, its water absorption effect is gradually reduced, and it is difficult to judge the amount of water absorption.

On this basis, when the heat conducting rod touches the outer surface of the cardboard for a long time, the temperature of the heat conducting rod will be transferred to the deformation layer, and the warm area on the surface of the paraffin stored in the accommodating outer capsule will melt from solid to liquid, and at the same time, the heat conducting rod at that place will be applied to the cardboard surface. The downward pressure is added, and the downward local extrusion force acts on the buffer water-absorbing layer after passing through the deformation layer and the upper plate layers, so that the shock-absorbing component at the pressure point is compressed inward, and the longitudinal distance of the corrugated elastic plate is reduced, that is, an inner depression is formed on the surface of the cardboard in space, and then in the interference of light, the refraction angle of the local area of ​​the force-bearing point on the surface of the cardboard shifts, and as the pressure at this point increases, the depth of the inner depression at the force-bearing point on the surface of the cardboard will gradually increase, and then the polarization increases, and then the local surface of the cardboard controlled by the heat conductive rod shows continuous color changes.

The spherical shell and the connecting rod are made of silicone material and are transparent. The corrugated elastic plate is made of elastic material, so that when the stress point on the surface of the buffering water-absorbing layer is deformed, the elastic properties of its own material can effectively reduce the shock of the local stress point of the cardboard, thereby reducing the loss of the paper surface. At the same time, copper sulfate is arranged in the spherical shell to absorb the surrounding water vapor, and its own color changes from colorless to blue, further increasing the color effect refracted by the surface of the cardboard. In addition, due to the depth of the color change, the user can judge the amount of water absorbed by the copper sulfate, and then the buffering water-absorbing layer can be replaced by adhesive to achieve efficient use of the cardboard.

[0047] Working principle of the present invention:

[0048] S1. Through the principle of light interference, the color of the cardboard surface with the colored mirror ink layer 6 inside will change with the deviation of the viewing angle, which plays the role of laser effect, making the mirror cardboard present a unique and changeable color sense. On this basis, when the heat-conducting rod touches the outer surface of the cardboard for a long time, the temperature of the heat-conducting rod will be transferred to the deformation layer 7, and the warm area on the surface of the paraffin 702 stored in the accommodating outer bag 701 will melt from solid to liquid, accompanied by the downward pressure exerted by the heat-conducting rod on the cardboard surface. After passing through the deformation layer 7 and the upper plate layers, the downward local extrusion force acts on the buffer water-absorbing layer 8, and then the shock-absorbing component 802 at the pressure point is compressed inward, and the longitudinal distance of the corrugated elastic plate 801 is The heat conduction rod is used to control the heat transfer of the paperboard. The heat conduction rod is used to control the heat transfer of the paperboard surface ... conduction of the paperboard surface. The heat conduction of the paperboard surface is reduced, that is, the paperboard surface forms an inner depression in space, and then in the interference of light, the refraction angle of the local area of ​​the cardboard surface at the stress point is offset, and as the pressure at the point increases, the depth of the inner depression at the stress point of the cardboard surface will gradually increase, and then the polarization will increase, and then the local surface of the cardboard controlled by the heat conduction rod will appear continuous color change. When the heat conduction rod is withdrawn from the cardboard surface, the cardboard surface is no longer heated and stressed, and then the heat-melted area containing the outer capsule 701 and the paraffin 702 filled therein is reset, and the paraffin 702 in the heat-melted area is gradually cooled and solidified. At the same time, along with the reset of the buffer water-absorbing layer 8, the half layers located on the top of the deformation layer 7 are also reset, and the refraction of the paperboard is restored to the initial state.

[0049] S2. The corrugated elastic plate 801 is spatially a regular tetrahedron and is interspersed in the trough of the corrugated elastic plate 801. The spherical shell 8021 and the connecting rod 8022 are made of silicone and are transparent. The corrugated elastic plate 801 is made of elastic material. When the stress point on the surface of the buffer water-absorbing layer 8 is deformed, the elastic properties of its own material can effectively reduce the shock of the local stress point of the cardboard, thereby reducing the loss of the paper surface. At the same time, copper sulfate 8023 is arranged in the spherical shell 8021 to absorb the surrounding water vapor, and its own color changes from colorless to blue, further increasing the color effect refracted by the surface of the cardboard. In addition, due to the depth of the color change, the user can judge the amount of water absorbed by the copper sulfate 8023, and then replace the buffer water-absorbing layer 8 through the adhesive tape 803.

[0050] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or modifications within the technical scope disclosed by the present invention; according to the technical plan and its improved conception of the present invention, all of which should be included under the protection of the present invention.
