| 摘 要： | 纯PVC在紫外光照射下也易脱去HCl而生成共轭双键,RM-PVC优良耐光老化机理主要是,红泥中的Fe_2O_3,能强烈地吸收紫外光,以及红泥中的钙、硅等其它一些成分也能一定程度地吸收紫外光,从而使基体PVC基本上免遭光能作用而降解、破坏。

| Abstract: | Under the radiation of ultraviolet ray,pure PVC can also evolve HCl easily to form the conjugated bonds in PVC Chain. We proposed that the mechanism of light stability of RM-PVC composite is that Fe2O3 and Ca,Si constituents in RM can absorb ultraviolet ray strongly to avoide the destruction of PVC. Therefore, RM-PVC has also very good light stability. |
