Paste for PVC (polyvinyl chloride) foaming wallpaper, PVC foaming wallpaper and preparation method thereof
The invention discloses a paste for PVC (polyvinyl chloride) foaming wallpaper, the PVC foaming wallpaper and a preparation method thereof. The paste for the PVC wallpaper comprises PVC paste resin, a potassium/zinc liquid heat stabilizer, a cell finishing agent, a viscosity reducing agent, a foaming agent, a plasticizer and a filler. The potassium/zinc liquid heat stabilizer, the cell finishing agent and the viscosity reducing agent are skillfully combined and applied to act synergistically with the AC (activated charcoal) foaming agent, thereby reducing the chemical decomposition temperature of the AC foaming agent, and further improving the foaming ratio of the PVC foaming wallpaper. With the adoption of the potassium/zinc liquid heat stabilizer, the heat stability of the paste for the PVC foaming wallpaper is further improved. The PVC foaming wallpaper disclosed in the invention has the advantages of good heat stability, high foaming ratio, uniform and fine cells, soft hand feeling and high cost performance.
