Abstract

The invention discloses thermochromic wallpaper and a production method thereof. The thermochromic wallpaper in layered structure comprises a bottom wallpaper base layer, an intermediate PVC (polyvinyl chloride) printed layer and a top variable color layer. The intermediate PVC printed layer is coated on the bottom wallpaper base layer. The top variable color layer is formed by coating thermochromic even ink slurry of printing ink and thermochromic powder on the intermediate PVC printed layer through a gravure printing wheel or cylinder printing wheel and drying. The production method includes: firstly, coating the intermediate PVC printed layer to the wallpaper base layer by printing, and drying; secondly, coating the thermochromic even ink slurry of printing ink and thermochromic powder on the intermediate PVC printed layer through the gravure printing wheel or cylinder printing wheel; and thirdly, conveying into a drying oven through a wallpaper printing line, and drying to obtain the thermochromic wallpaper which can meet the requirement for personality, is artistic and is capable of indicating indoor temperature difference.

Description

technical field [0001] The invention belongs to the technical field of wallpaper, and relates to a temperature-sensitive color-changing wallpaper and a preparation method thereof. Background technique [0002] With the rapid development of social economy, the quality of people's material and cultural life is also constantly improving, and there is also a constant pursuit of decorative materials used on walls - from lime, paint to wallpaper, and then the development of wall paint. The above-mentioned various wall decoration materials used in different eras have their advantages, but at the same time, they all have the defects of poor individuality and artistry, that is, they cannot meet everyone's needs, and can only be what varieties are available on the market. Just use what kind of variety. [0003] With the continuous improvement of domestic living conditions, people's requirements for interior wall decoration are also increasing day by day. While pursuing beauty, they a...
