Surface Modification of Magnesium Hydroxide Sulfate Hydrate Whiskers and its Application Mechanism in Polypropylene
摘要
Abstract
The surface modification method of emulsion polymerization to prepare methyl methacrylate (MMA) modified magnesium hydroxide sulfate hydrate (MHSH) whiskers was reported. Scanning electron microscope (SEM), Energy diffraction spectrum (EDS), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FT-IR) were used to characterize the effect of surface modification. It was found that the whisker is successfully coated with poly-methyl methacrylate (PMMA) and the modification does not change the whisker crystal structure. The mechanical and flame retardant properties of the composites were investigated in order to evaluate the modification effect. It was found that the tensile strength of Propene Polymer (PP) composites can be improved by 92 percent after adding modified whiskers. The flame retardant effect is better when the content of whiskers is higher. The main impact of surface modification on the composite materials is the improvement of its mechanical properties, and the effect of the surface modification on flame retardancy of the whisker is little.关键词
