Abstract

The invention discloses a water-resistance thermosensitive color-changing liquid wall paper and a preparation method thereof. In the liquid wall paper, a temperature-changing material is used as a main color-changing material, and a silicone-acrylate emulsion is used as a main film-forming substance. The liquid wall paper also comprises distilled water, a cosolvent, a film-forming agent, a thickener, a defoamer, a dispersing agent, a wetting agent, an extender pigment and a mildew preventive component. In the water-resistance thermosensitive color-changing liquid wall paper, organic silicon modified acrylic emulsion is used as the film-forming component, thereby improving the water resistance, stability, heat resistance and film-forming ability of the wall paper; and the organic silicon modified acrylate emulsion prepared by a seed emulsion polymerization method has a good stability and small emulsion particles, the contamination resistance of the prepared paint is good, and the formed adhesive film has excellent water resistance and contamination resistance self-cleaning property and excellent atmosphere resistance ageing property and is suitable for inner walls of a building.

Description

technical field [0001] The invention relates to a water-resistant temperature-sensitive color-changing liquid wallpaper and a preparation method thereof, in particular to a pollution-free and environment-friendly liquid wallpaper whose color changes with temperature changes. Background technique [0002] At present, most of the materials that people use for indoor and outdoor wall decoration are wallpaper, wall covering and paint. Paints are harmful to human health due to their varying degrees of organic volatile pollutants. Traditional wallpapers and wall coverings are often expensive, and they are prone to yellowing, peeling, and fading after long-term use. These defects limit the popularity of their applications. . [0003] As a new type of decorative material, liquid wallpaper is non-toxic, non-polluting and environmentally friendly, and its cost performance is higher than traditional decorative materials. The liquid wallpaper is made of silicone-modified acrylic emuls...
