“…Nowadays, NR-based nanocomposites, among which those containing layered silicates and carbon nanotubes [1][2][3][4] are of major interest, have attracted much attention, due to their enhanced properties at considerably less filler content compared with those of conventional NR compounds. These improvements in mechanical properties, thermal behavior, abrasion resistance, gas permeability etc., are especially remarkable when good and even dispersion of the filler on a nano-level within the rubber matrix is achieved [5][6][7].…”

Focusing on application aspects of the rubber nanocomposites and the production and testing of industrial-sized samples, this study was performed in two phases. First, natural rubber (NR)/organomontmorillonite (OMMT) nanocomposites containing 2-14 phr OMMT were prepared on a laboratorysized two-roll mill. The vulcanization behavior and mechanical properties of NR/OMMT composites were compared with a referent NR compound containing 60 phr carbon black (N330) as a reinforcing filler. The x-ray diffraction (XRD) analyses showed a predominant intercalated structure for all OMMT nanocomposites. As a result, the organoclay behaved as an effective reinforcement for NR, even at loadings as low as 2 phr. This nanocomposite exhibited an improvement in tensile strength of 29% and in elongation at break of 61% in comparison with the referent NR/N330 compound. With the estimated optimal filler content, in the second phase, bulk NR/OMMT-5/steel samples were successfully produced for dynamic testing. The dynamic moduli were investigated by the method of forced vibrations. Compared to the NR/N 330 samples, NR/OMMT-5 samples showed improved hysteresis, with very low dissipating energy per cycle and significantly reduced Mullins effect.Keywords: organo-montmorillonite; nanocomposites; natural rubber; dynamic properties ДОБИВАЊЕ И СВОЈСТВА НА ПРИРОДНА ГУМА НАПОЛНЕТА СО ОРГАНСКИ МОДИФИЦИРАН МОНТМОРИЛОНИТ: ОД ЛАБОРАТОРИСКИ ПРИМЕРОЦИ ДО МАСИВЕН МАТЕРИЈАЛИстражувањата во овој труд се направени во две фази фокусирајќи се на применливоста на нанокомпозитите на база на гума и на добивањето и карактеризација на примероци со индус-триски димензии. Прво беа подготвени лабораториски примероци нанокомпозити природна гума (NR)/органски модифициран монтморилонит (OMMT) со 2-14 phr OMMT на лабораториски дво-валјак. Вулканизацијата и механичките својства на композитите NR/OMMT се споредувани со референтен примерок на природна гума наполнета со саѓи (N330). Рендгенската дифракција (XRD) покажа дека кај сите нанокомпозити со OMMT доминира интеркалирана структура. Како резултат на тоа, органски модифицираната глина се однесува како ефикасен зајакнувач на природната гума, дури и при концентрации од само 2 phr. Нанокомпозитот се одликува со јачина на истегнување за 29 % поголема од онаа на референтниот примерок со саѓи (NR/N330), како и со зголемено издолжување (за 61 %). Во втората фаза, по определување оптимална количина на полнилото, произведени беа индустриски примероци NR/OMMT и сендвич-структура NR/OMMT-5/челична A. Ivanoska-Dacikj, G. Bogoeva-Gaceva, A.

Динамичкиот модул на материјалот е испитуван со методот на принудни вибрации. Произведениот масивен нанокомпозитен материјал NR/OMMT-5 се одликува со подобрена хистереза, многу ниска енергија на дисипација за циклус и значително намален Mullin-ов ефект во споредба со референтниот материјал NR/N330.

“…However, high loadings of these fillers are required to obtain desirable properties. Incorporation of reinforcing fillers such as carbon black improves stiffness and strength of rubber (Tabsan et al, 2010). Hence, the abrasion resistance is improved by suppressing tearing of the rubber under the sliding contact (Gent & Pulford, 1983).…”

“…less than 10 phr.). [7][8][9] NR-organoclay nanocomposites (NROCNs) have been synthesised with enhanced material properties using different preparative techniques such as direct melt blending, solution blending and latex compounding by different research groups. [10][11][12] However, irrespective of the preparation techniques, exfoliation of the organoclay particles into individual clay platelets of nanometre-scale thickness and dispersing them uniformly within the NR matrix are the key factors to enhance the physical properties of the NR compounds.…”

Organically modified montmorillonite (OMMT) clay was intercalated with low-molecular weight polyethylene glycol (PEG) oligomer at melt stage. The intercalation behaviour of PEG into the OMMT clay galleries and its interaction with clay platelets were characterized with X-ray diffraction (XRD) and differential scanning calorimetric techniques. A natural rubber (NR)-organoclay nanocomposite (NROCN) was prepared by melt-compounding of NR with PEG-treated organoclay (P-OMMT) and other compounding chemicals using a laboratory-scale internal mixer. XRD analysis of the nanocomposites revealed the intercalation of NR molecules into the P-OMMT clay galleries and subsequent exfoliation during the melt-compounding process. Vulcanization characteristics of the NROCN, especially processing safety and optimum curing time, have been interpreted with reference to the organic modifier of the montmorillonite clay, PEG modification and the degree of exfoliation. Solid-state mechanical properties of P-OMMT clay-filled NROCN vulcanizates have shown a significant enhancement in stiffness and strength characteristics whilst without scarifying the elasticity of the nanocomposites. Results have been explained in terms of the degree of exfoliation, dispersibility of the organoclay and strain-induced crystallization of the natural rubber.
