Preparation and Characterization of CaSiO3 /Natural Rubber Composite
A series of calcium silicate/rubber composites with different CaSiO3 contents was prepared. micro-morphology, vulcanizing properties and mechanical properties of CaSiO3/rubber were were characterized. It can be observed that mean particle size of CaSiO3 was 2.627 µm. The micro-morphology of particles were honeycomb structure on the particles of CaSiO3. As compared with NR, the least torque enhanced wtih increasing CaSiO3 content. Curing rate reduced with a rise of CaSiO3 content. The tensile strength and the elongation of composites was increased with increasing CaSiO3 content.
