Embodiment 1
[0006] Example 1, since cobalt dioxide cannot be directly added to the plastic spraying solution, it is necessary to prefabricate the color-changing additive. The method is: dissolve 3% cobalt dioxide in water, add an appropriate amount of light calcium carbonate to soak for more than 30 minutes, and then dry it , crushed into a fine powder of more than 300 mesh, so that cobalt dioxide can be attached to the calcium carbonate carrier. When producing high-foaming wallpaper, add 6% color-changing powder to the plastic spraying liquid, stir evenly, and spray according to the conventional wallpaper spraying method to get the color-changing wallpaper. If it is an aqueous solution, it is prepared with cobalt dioxide, ethanol, shellac, rosin, sodium lauryl sulfate, saponin, water and colorants. The ratio is 12% cobalt dichloride, 60% ethanol, 5% shellac, 3% rosin, 2% sodium lauryl sulfate, 1% saponin, 15% water, appropriate amount of coloring material (the above are all weight ratio...
Embodiment 2
[0007] Example 2, the method of prefabricating the color-changing additive is: dissolving 5% cobalt dioxide in water, adding an appropriate amount of light calcium carbonate to soak for more than 30 minutes, adding an appropriate amount of coloring material, then drying, and pulverizing into a fine powder of more than 300 mesh, In order to make cobalt dioxide attached to the calcium carbonate carrier. When producing high-foaming wallpaper, add 7% color-changing powder to the plastic spraying solution, stir evenly, and spray according to the conventional spraying method for wallpaper to get the color-changing wallpaper. If it is an aqueous solution, it is prepared with cobalt dioxide, ethanol, shellac, rosin, sodium lauryl sulfate, saponin, water and colorants. The ratio is 14% cobalt dichloride, 65% ethanol, 6% shellac, 4% rosin, 2.5% sodium lauryl sulfate, 1.5% saponin, 18% water, appropriate amount of coloring material (the above are all weight ratio). In the case of water...
Embodiment 3
[0008] Embodiment 3, the method for prefabricating the color-changing additive is: dissolving 7% cobalt dioxide in water, adding an appropriate amount of light calcium carbonate to soak for more than 30 minutes, adding an appropriate amount of coloring material, then drying, and pulverizing into a fine powder of more than 300 mesh, In order to make cobalt dioxide attached to the calcium carbonate carrier. When producing high-foaming wallpaper, add 8% color-changing powder to the plastic spraying liquid, stir evenly, and spray according to the conventional spraying method of wallpaper to get the color-changing wallpaper. If it is water preparation, it is prepared with cobalt dioxide, ethanol, shellac sheet, rosin, sodium lauryl sulfate, saponin, water and colorant. The proportion is 15% of cobalt dichloride, 70% of ethanol, 7% of shellac, 5% of rosin, 3% of sodium lauryl sulfate, 2% of saponin, 20% of water, and appropriate amount of pigment (the above are all weight ratio). ...
