How α-Zirconium Phosphate Apply in Plastic Product
α-Zirconium Phosphate (a-ZrP) is a kind of layered inorganics, it will still keep its layered structure when the guest is inserted into the layers and it is also a filler for the preparation of polymer/layered inorganic nanocomposites due to its high ion-exchange capacity, tunnable size and aspect ratio, and narrow size distribution. However, the high degree of crystallinity and small layer spacing have hindered the well.
Dispersion of α-ZrP in polymer. In order to improve the compatibility of α-ZrP with polymers, a novel method for the preparation of organic modified α-ZrP has been presented in this paper. In this novel method, a precursor was obtained after a-ZrP was intercalated by methylamine. Then the organically-modified a-zirconium phosphate had been synthesized through ion-exchange of the methylamine cations in the precursor with styryl quaternary ammonium ions, which had been prepared from the reaction of N, N-dimethyl octadecylamine with 4-chloromethyl styrene. Then, the nanocomposite had been prepared through melt blending of plystyrene with this organically-modified a-ZrP. XRD results indicated that the d-spacing of ZrP-DMA-CMS layers had been enlarged from 0.8nm to 4.0nm, while the layer d-spacing of PS/a-ZrP nanocomposites had been enlarged from 4.0nm to 4.3nm.
Experimental of mechanical properties indicated that polystyrene/a-ZrP nanocomposites with good mechanical properties have been obtained. The tensile strength, stretch modulus, the reputure elongation and impact strength have been increased by 4%, 21%, 8%, 43% respectively at α-ZrP loading of 1%.
