Abstract

The invention discloses reflective ink and a scraping structure. The raw materials for preparing the reflective ink comprise, by mass, 30-50 parts of base ink and 0.6-1.6 parts of foaming agent. The reflective ink can generate a plurality of micro bubbles in the stirring process due to the action of the foaming agent. When the reflective ink is used for preparing a scraping structure, a plurality of round micro-spaces with smooth inner surfaces are formed in the ink layer after the reflective ink is dried. The incident light will generate multiple reflection phenomena on the upper and lower surfaces of the micro-space respectively, so that the reflected light reaching human eyes via the image-text layer will be negligible. Thereby realizing the effect of covering the image-text layer. In addition, compared with the traditional reflective ink, the reflective ink can realize a good covering effect by single printing, and the process cost can be greatly reduced.

Description

Reflective ink and scraping structure Technical Field The invention relates to the technical field of printing ink, in particular to reflective printing ink and a scraping structure. Background The scraping structure comprises a basal layer, an image-text layer, a release layer and a covering layer which are arranged in a laminated manner, wherein the covering layer contains a large number of pigment particles, and the light rays reflected by the image-text layer back to human eyes are reduced to zero through the absorption and reflection of the incident light rays of the pigment particles, so that the covering effect on the image-text layer is realized. However, this process has a problem that the masking effect of the single masking layer is not ideal, and the masking effect is often expected by laminating the masking layer several times, which results in high process cost. Disclosure of Invention Based on this, it is necessary to provide a reflective ink and a scraping structure to solve the above problems. The reflective ink is used for preparing a scraping structure, and comprises the following raw materials in parts by mass: 30-50 parts of base ink and 0.6-1.6 Parts of foaming agent. In one embodiment, the foaming agent is a nonionic foaming agent or an ionic foaming agent. In one embodiment, the nonionic foaming agent is at least one selected from polyoxyethylene ether foaming agents, polyol foaming agents, fatty acid alcohol amide foaming agents and alkyl glycoside foaming agents. In one embodiment, the ionic blowing agent is selected from at least one of an anionic blowing agent, a cationic blowing agent, or a zwitterionic blowing agent. In one embodiment, 1-10 parts of the architecture material is also included. In one embodiment, the architecture material is an inorganic whisker. In one embodiment, the inorganic whisker is selected from at least one of an oxide whisker, a carbide whisker, a borate whisker, a sulfate whisker, a silicate whisker, a fluoride whisker, a titanate whisker, and a metal whisker. In one embodiment, the oxide whiskers are tetrapod-like zinc oxide whiskers. In one embodiment, the surface of the inorganic whiskers is subjected to a hydrophobic treatment. The reflective ink contains a small amount of foaming agent, and a plurality of microbubbles are generated by the reflective ink due to the action of the foaming agent in the stirring process. When the reflective ink is used for preparing a scraping structure, a plurality of round micro-spaces with smooth inner surfaces are formed in the ink layer after the reflective ink is printed and dried. At the moment, the micro-space has the advantages that in the first aspect, no matter the incident light is incident from any angle, the first reflection phenomenon and the second reflection phenomenon are respectively generated on the upper surface and the lower surface of the micro-space, so that most of the incident light cannot reach the image-text layer due to reflection. In the second aspect, after a small amount of incident light passes through the micro-space and reaches the image-text layer, the light reaches the micro-space again through reflection of the image-text layer, at this time, the third reflection phenomenon and the fourth reflection phenomenon occur again on the lower surface and the upper surface of the micro-space, and after multiple reflections, the reflected light reaching human eyes through the image-text layer is negligible. In the third aspect, the light reflected by the micro-space and entering the person is relatively strong, and the light reflected by the image-text layer and entering the human eye is relatively weak, so that the former will cause serious interference to the latter, which will further reduce the visibility of the image-text layer, thereby realizing the effect of covering the image-text layer. The reflective ink greatly reduces the light rays reflected from the image-text layer into personnel through multiple reflection, and visual interference phenomenon is generated between the reflected light, so that the image-text layer is further invisible to naked eyes. Compared with the traditional reflective ink, the reflective ink can realize a good covering effect by single printing, and the process cost can be greatly reduced. The scraping structure comprises a basal layer, an image-text layer, a release layer and a reflecting layer which are arranged in a laminated mode, wherein the reflecting layer is obtained by printing and drying the reflecting ink.
