Abstract: PVC paste was filled with Liesegang pattern six-rings rock powder forming a composite. Gravimetric analysis showed that the decomposition temperature of the six-rings rock was above 600 ℃. The rock powder was finely dispersed in PVC paste with a particles size about 600 nm. When the content of the rock powder was 3 wt%, the release rate of anion was above 1500 ions/cm3, which met the standard of WHO.
Key words: negative ions, PVC paste resin, natural mineral materials, foamed PVC, Liesegang pattern
