Marble waste as sludge is collected from Marble industry, as a way of solving the environmental problem of industrial waste. The sludge was dried, ground and passed through desire sieves (10, 15, 20, 37 and 75 μm), This powder was characterized by the X-ray fluorescence technique and then incorporated in the formulation of NR composites with different loading of micro sized MS particles (20, 40, 60, 80 and 100 parts per hundred of rubber, phr). The cure characteristics, mechanical properties and swelling properties of MS/NR composites were evaluated. Results indicate that minimum torque, maximum torque, tensile strength, modulus, tear strength, hardness, crosslink density were increased while the scorch time, cure time, cure rate, cure rate index (CRI), elongation at break, compression set, rebound resilience, abrasion loss, swelling coefficient, average molecular weight and filler-rubber interaction decrease with increasing MS loading

“…Reinforcement concerns finished elastomeric parts; but it is quite remarkable that flow properties of filled compounds begin to significantly differ from those of unfilled compounds when the filler has reinforcing capabilities. In addition to usual hydrodynamics effects, reinforcing fillers impart indeed other modifications in flow properties whose origin is assigned to strong interactions arising between the rubber macromolecules and the filler particles (14,15). Recognition of the role of the main factors influencing interfacial adhesion and proper surface modification may lead to significant progress in many fields of research, as well as in related technologies (16,17).…”

The incorporation of nanoparticles to rubber compound with subsequent conversion to a network by crosslinking leads to a materials of great complexity. As compared to micron size filler particles the nano size filler particles are able to occupy substantially greater number of sites in the polymer matrix. Selecting proper network precursors for a specific application requires an evaluation of the environment in which it is anticipated to operate and the performance required. Compared to carbon black, silica has two advantages for fundamental investigations: it has a simpler geometry and it can be functionalized in different ways to control its degree of interaction with the polymer (i.e.), compatibility to enhance dispersion and/or mechanical coupling by covalent or non-bonded interactions. In this contribution, studies of elastomers based on ethylene-propylene diene monomer (EPDM) rubber and acrylonitrile butadiene rubber (NBR) have been performed. To enhance the quality of elastomers, an attempt was made to prepare technologically feasible blends comprising non-polar EPDM rubber and NBR with high performance. The properties of elastomeric composites were determined before and after thermal aging in an air circulating oven. The elastomers based on EPDM/NBR (80:20) were reinforced either with high abrasion furnace carbon black (46 nm) or with precipitated silica (22 nm) or its combination. Comparative values of tensile strength before and after weathering were analyzed. It was estimated considerable performance enhancement of rubber blends by reinforcing with dual active fillers.

“…These phenomena can be avoided if strong interactions are used such as covalent bonds, as in nanoparticle‐crosslinked polymers. As compared to micron‐sized filler particles, the nano‐sized filler particles can occupy a substantially greater number of sites in the polymer matrix . The interaction between silica and rubber and its influences on properties of rubber have been studied extensively for decades.…”

In this applicative work, two types of silica filler were used to increase the adhesion strength between steel and elastomeric hybrid materials based on chlorosulfonated polyethylene rubber (CSM) and polychloroprene rubber (CR) as network precursors. Precipitated silica (PS) with the average size of primary particles 15 nm and diatomaceous earth (DE) with the average size of primary particles 28 μm were used to ascertain differences in metal‐elastomer compounds adhesion strength caused by different particle size. The ratio of network precursors in CSM/CR rubber blends was 50:50 (w/w). The filler loading was in the range of 0–35 phr. Characteristics of the obtained composites were examined by combining the cure kinetics, adhesion strength and the dynamic mechanical properties. The viscoelasticity of obtained hybrid materials was assessed by the mechanical spectrometer (in a single cantilever bending mode) in the temperature range from −50 °C to 150 °C using multifrequency mode.
