Morphology And Mechanical Properties

The effects of the montmorillonite clay surface modified with 25-30 wt% of methyl dihydroxyethyl hydrogenated tallow ammonium (Clay-MHA) on morphology and mechanical properties of poly(lactic acid) (PLA)/acrylonitrile-butadiene rubber copolymer (NBR)/Clay-MHA composites were investigated. The composites of blends of PLA/NBR with Clay-MHA were prepared by melt mixing in an internal mixer and molded by compression molding. The ratio of PLA and NBR was 80/20 by weight and the Clay-MHA content was 1, 3, 5 and 7 phr. The results showed Young’s modulus and stress at break of the composites increased with increasing Clay-MHA content. While the tensile strength and strain at break of the composites decreased with increasing Clay-MHA content. Scanning electron microscopy analysis showed that the addition of Clay-MHA could improve the miscibility of PLA and NBR to be homogeneous blends and the pore in polymer blends was disappeared.

Organoclay nanoparticles (Cloisite® C10A, Cloisite® C15) and their combination with carbon black (N330) were studied as fillers in chloroprene/natural/butadiene rubber blends to prepare nanocomposites. The effect of filler type and load on the physical mechanical properties of nanocomposites was determined and correlated with its structure, compatibility and cure properties using Fourier Transformed Infrared (FT-IR), X-ray Diffraction (XRD), Thermogravimetric Analysis (TGA) and rheometric analysis. Physical mechanical properties were improved by organoclays at 5–7 phr. Nanocomposites with organoclays exhibited a remarkable increase up to 46% in abrasion resistance. The improvement in properties was attributed to good organoclay dispersion in the rubber matrix and to the compatibility between them and the chloroprene rubber. Carbon black at a 40 phr load was not the optimal concentration to interact with organoclays. The present study confirmed that organoclays can be a reinforcing filler for high performance applications in rubber nanocomposites.
