Abstract:Abstract. Purpose of this study was to determine the mechanical properties and morphology of composite natural rubber and natural bentonite with addition of Na-bentonite filler and carbon black to natural rubber. The method is carried material mixed with filler composition variations (0,10,20,30) phr using open mill for 6 min. Results of the open mill is vulcanized at a temperature of 170 o C. Further testing mechanical properties and morphology. Results showed that the addition of Na-bentonite filler and carb… Show more
“…This restricts the mobility of chains hence causes lower percentage elongation values. 36,37 N339 nanofillers reinforced rubber composites show a maximum stretchability of about 460% due to good compatibility of polymeric chains of rubber and N339 nanofillers.Figure 8.Variation in elongation of different rubber compounds containing carbon black nanofillers.…”
A detailed analysis of the rubber composites is necessary for the designing and fabrication of advanced rubber products. In this study, composite materials are synthesized by adding different nanofillers of carbon black nanoparticles into epoxidized natural rubber (ENR). The specific characteristics of carbon black (CB) affect the crosslinking density between CB and polymeric chains in ENR. The effects of particle size, structure, thermal conductivity, and functionality of CB on rheology and mechanical properties of filled reinforced ENR are examined. The composite materials are thoroughly characterized for their abrasion, rheology, tensile, hardness, elongation, resilience, and compression behavior. The results revealed that various properties of composite materials depend on the characteristics of the reinforcing CB fillers. It was found that lower particle size and ordered structure provide good tensile strength, tear strength, abrasion, and aging resistance. In contrast, larger particle size and a lower ordered structure provide high flow rate, low hardness, excellent re-bounce, and good compression set characteristics.

“…Bukit et al [8] found that the application of bentonite as nanofillers for high density polyethylene (HDPE) polymeric system could enhance the mechanical properties of the system with the best performance at 2-6 wt % of bentonite. Similarly, Ginting et al [9] discovered that the addition of Na-bentonite filler and carbon black could influence the rubber. Related to that, the utilization of bentonite to other polymeric systems needs to be conducted in order to develop the study about polymer nanocomposites.…”
Nanocomposites are solid structures with dimensions of nanometre scale and can also be porous, colloid, gel and copolymer. In general, the nanocomposite material demonstrates different mechanical, electrical, optical, electrochemical, catalytic and structural properties from each component [1]. Based on their matrix materials, nanocomposites can be classified into three different groups, namely ceramic matrix nanocomposites, metal matrix nanocomposites and polymer matrix nanocomposites [2]. Polymer matrix nanocomposites, the system consisting of a polymer or copolymer having nanoparticles or nanofillers dispersed in the polymer matrix, have attracted researchers' attention nowadays due to their advantages in physical properties, such as mechanical and thermal properties over the polymeric system [3]. Currently, the most natural material that is widely used as a nano-sized filler for polymer nanocomposites is bentonite. Natural bentonite processing itself can be conducted by several methods, such as co-precipitation method and ball milling method [4,5]. A nano bentonite-making study using ball mill
“…For example, combining bentonite/rice husk in the HDPE matrix can improve the mechanical properties of the composite [6]. In addition, combining bentonite with carbon black, which is used as a natural rubber filler, can affect tensile strength, elongation at break, modulus of elasticity, and composite hardness [7,8]. In addition, the addition of nano SiO 2 and bentonite was able to increase the compressive strength of the mortar [9].…”
Bentonite-OPBA nanocomposite has been made. The preparation of OPBA and bentonite was carried out by calcination process at a temperature of 700oC for bentonite and 500 °C for OPBA and a ball mill process for 10 hours and coprecipitation method with a solution 6 M HCl. Then nano bentonite was synthesized with surfactant Cetyl Trimethyl Ammonium Bromide (CTAB). The XRD analysis obtained a Bentonite-OPBA particle size of 14.46 nm, with a Tetragonal crystal system and density of 3.01200 g/cm3. XRF analysis obtained SiO2 content of 55.1 % FTIR analysis obtained absorption band detected at 981.33 cm−1 indicates that the increase in silica strengthening has in the polymerization process.
