Abstract:
     This invention discloses super molecule plant layer 2-benzene group benzimidazole-5 sulfonic acid and its preparation method and application. The character of brucite can be plant layer assembling packaged is used, anion of the 2-benzene group benzimidazole-5 sulfonic acid is inserted into the brucite layers, preparation layers guest is PSA anion super molecule plant layer structure. Its chemical formula is [M2 1-xM3 x(OH)2](C13H10N2O3S)-x.mH2O, absorptivity to 230-340nm wave band ultraviolet ray is more than 80 percent. The ultraviolet ray absorbing range and ability of the material is greatly improved compared to the PSA, and its interlayer substance obvious decomposition temperature is about 520 degree centigrade, its heat stability is improved compared to the PSA. The material can be used as ultraviolet light absorbent as polypropylene, polycarbonate, vinyl cyanide-butadiene styrol copolymer and polyurethane.
