CR is masticated in a tworoll mixing mill, and then the requisite amount of MgO is added and again masticated. After that uncoated and silicacoated nano CaCO 3 are added and masticated for sufficient time. Then, stearic acid and accelerator are incorporated into the rubber matrix. At last, ZnO is added after cooling down the mixing mill at 30 ...
In our former work , precipitated calcium carbonate nanoparticles coated with fatty acids were added into highdensity polyethylene, and the impact strength of the polymeric composites was increased as the amount of stearic acid increased. We believed that the interfacial adhesion between PCC and HDPE was affected by the amount of fatty acid ...
Apr 10, 2012018332This study investigates the effects of calcium carbonate CaCO 3 nanoparticles on the mechanical and thermal properties and surface morphology of polycaprolactone PCLchitosan nanocomposites.The nanocomposites of PCLchitosanCaCO 3 were prepared using a melt blending technique. Transmission electron microscopy TEM results indicate the average size of nanoparticles
The coated calcium carbonate is specialty mineral, which has a stearic acid coating that makes the hydrophilic surface of the calcium carbonate less hydrophilic. This coating improves dispersion of the calcium carbonate particles into the polymer melt. EMAIL INQUIRY to 3 suppliers .
The present invention provides a composite material comprising calcium carbonate particles dispersed within a polypropylene matrix, wherein the calcium carbonate particles have a size within the range of 1 to 100 nm and a filling ratio of less than about 30 by volume, more preferably less than about 10 by volume. The particles have a mean size of around 40 to 50 nm.
