Problems solved by technology

In order to improve the quality of wallpaper, the moisture resistance of many wallpapers has been effectively improved at present, and the use time is getting longer and longer. However, people still expect to have more color or pattern changes without changing the wallpaper, so as to cultivate people's interest in life. So color-changing wallpaper came into being
However, the wallpaper currently on the market directly prepares the pattern color-changing layer through temperature-changing materials, which has poor temperature-changing effect, poor weather resistance, and the temperature-changing effect is not long-lasting.

Abstract

The invention relates to the technical field of wallpaper, in particular to temperature sensitive ink and a preparation method, temperature sensitive wallpaper and a preparation method of the wallpaper. The temperature sensitive wallpaper is composed of a base material layer, a densification treatment layer, an ink texture layer, a temperature-sensitive reversible color changing layer and a transparent resin layer which are stacked in sequence, and ink adopted by the temperature-sensitive reversible color changing layer is formed by mixing resin emulsion, reversible temperature-sensed color-changing pigment, a cross-linking agent, a light stabilizer, a dispersing agent, a flatting agent and a defoaming agent; the temperature sensitive wallpaper obtained through printing is good in weather resistance and pattern color developing effect, multiple dynamic change forms exist, the wallpaper can be changed to be colorless from a colored state and can also be changed to be colored from a colorless state, the service time is long, and the damp and mildew proofing effect is good.

Description

technical field [0001] The invention relates to the technical field of wallpaper, in particular to a temperature-changing ink and a preparation method, a temperature-changing wallpaper and a preparation method of the wallpaper. Background technique [0002] Wallpaper is also called wall covering or wallpaper, and paint, ceramic tile, etc. become one of the main products of indoor wall decoration. [0003] The advantage of wallpaper is that it has diverse patterns, good decorative effects, and easy replacement. You can change the interior decoration style by changing the wallpaper at any time, so it is very popular among people today.
