Abstract
The invention relates to a color-changing tape, comprising a transparent base layer and an adhesive layer, the bottom surface of the transparent base layer is bonded to the adhesive layer, and the transparent base layer is provided with a color-changing material, and the color-changing material includes color-changing ink, heat-sensitive There are three types of materials: material and photosensitive material, the color-changing ink is water-based screen printing ink, the water-based screen printing ink is printed on the top surface of the transparent base layer to form a printing layer 1, and the heat-sensitive material is heat-sensitive color-changing microcapsules , the described thermochromic microcapsule mixed adhesive forms the adhesive layer and is melted and coated on the bottom surface of the transparent base layer, the described photosensitive material is photosensitive MC powder, and the described photosensitive MC powder is mixed in ink and printed on the top surface of the transparent base layer to form Printing layer two. The beneficial effects produced by the invention are as follows: it has the characteristics of discoloration upon encountering water, discoloration with temperature, and discoloration upon encountering strong light, which is convenient for quick inspection and maintenance, and facilitates popularization.
Description
technical field [0001] The invention relates to the technical field of tape manufacturing, in particular to a color-changing tape. Background technique [0002] Tape has become an indispensable stationery in people's daily life. Whether in company or family, tape is used to stick envelopes, packaging or box sealing and other sticking purposes every day. Therefore, tape can be used in daily life. known as bulk consumables. [0003] In the early days, all the adhesive tapes were monotonous and unchanged in appearance and color. Except for transparent tapes, they were opaque tapes, that is, only tapes with a sticking effect. The diversification of development, such as adding a variety of colors to the basic adhesive material by electroplating to distinguish products, and these colors are produced by electroplating, so they have brightness, but have The brightness does not vary with incident light. In addition, various patterns are added to the basic pasting material by means...
