Micro-crystal muscovite is with increased acid and alkali, anti-corrosion, heat, insulation, thermal expansion coefficient is small, strong weatherability, good suspension and leveling, anti-aging and so the role of ultraviolet radiation is an ideal new type of filler. By orthogonal experimental design,the experimentation of improving surface modification to powder stuffing of microcrystal muscovite using borate ester represented the effect of modification through viscosity,modified powder/polyvinyl chloride polymer composite material's mechanical property and infrared spectroscopic analysis.
According to the result of the analysis: powder stuffing of microcrystal muscovite modified by borate ester has been improved magnificently on its dispersibility in organic medium,so the compactedness of powder stuffing of microcrystal muscovite modified by borate ester in high polymer can be raised substantially; by using powder stuffing modified by borate ester,the mechanical property of modified powder/polyvinyl chloride polymer composite material can also be improved; the borate ester cladding on the surface of powder stuffing of muscovite absorb in physical way.
