- Abstract
Huntite hydromagnesite (HH) is compatibilised with the polypropylene (PP) matrix by using silane coupling agents before addition to polymer. In addition, composites with maleic anhydride grafted polypropylene (Ma-g-PP) matrix were prepared in order to compatible with HH. Composite materials which contain 10% HH content were prepared by using twin screw extruder which is the most common method in industry. Granulased composites were shaped with injection molding. Tensile test, dynamic mechanical analysis (DMA) and melt flow index tests were applied to composites, respectively. In addition to the mechanical properties of prepared composites, water absorption test of the composites were performed to consider their outdoor usage conditions. Scanning electron microscopy (SEM) was used to observe the dispersion of huntite particles inside the polypropylene matrix. Mechanical properties of composites obtained by using silanized huntite and Ma-g-PP were improved. SEM images show that composites which contain silanized huntite and Ma-g-PP have good dispersion of particles inside the PP matrix and particle surfaces were compatible with polymer surface. This results also support the mechanical test results. Distinct changes did not observed for the melt flow index results of the composites. This results indicate that addition of the huntite to the PP matrix causes no obvious problem to the processibility of the polymer.
