“…The reduction in the quantity of ZnO is worthwhile because it has high density and some soluble zinc compounds have been classified as toxic to aquatic species. In the past years, a totally different and new approach to reduce ZnO in rubber compounding was introduced by Hepburn et al, the use of multifunctional additives (MFAs), such as a bifunctional diamine, which can function as a simultaneous cure activator and accelerator for sulfur vulcanization, and it was found that the use of ZnO and stearic acid in the compound formulation was not necessary. In previous years, most of the relevant research about nano ZnO was focused on using it as a substitute for micro ZnO in the sulfur vulcanization of rubber compounds.…”

Viscoelastic Behavior and Reinforcement Mechanism in Rubber Nanocomposites in the Vicinity of Spherical Nanoparticles

The viscoelastic behavior and reinforcement mechanism of nano ZnO reinforced natural rubber (NR) nanocomposites were investigated in this study. Dynamic mechanical analysis was performed to investigate the nature of the constrained polymer region in NR−nano ZnO nanocomposites, and the constrained polymer region is responsible for the reinforcement mechanism. The viscoelastic and tensile properties of NR nanocomposites were investigated with respect to the effect of nanofiller loading. All the nanocomposites showed a significant increase in storage modulus in the glassy and rubbery regions, the shift of the tan δ peak to the higher temperature region, and the lowering of the tan δ peak intensity compared to neat NR. The enhancement in the modulus is related to the weight % of the added nano ZnO as well as the volume of the constrained rubber chains in the proximity of ZnO nanoparticles. The study of the constrained volume of the polymer indicates that the structure of the nanocomposite possesses a moderately strong interfacial interaction between rubber chains and ZnO nanoparticles. The type of rubber−nanofiller interaction strongly influences the amount and modulus of the constrained region and contributes to the enhancement in the storage modulus of the resulting nanocomposites. The volume fraction of the constrained region of the NR nanocomposites was found to have good linear correlation with the weight % of nano ZnO. It was also understood that there should exist an optimum cross-linking density for a certain nanofiller reinforced rubber system, as well as partial physical adsorption of macromolecular rubber chains on the nanofiller surface. An optimum nanofiller loading is necessary for moderately strong rubber−nanofiller interaction and hence for the enhancement in the mechanical properties of the NR nanocomposites. A core−shell morphology model and constrained polymer model have been proposed to explain the constrained polymer chains in the NR−nano ZnO nanocomposite system on the basis of these results.

The strength of the textile bonded seams was analyzed. Two or more fabric layers joining are based on use of base layers structural properties and thermoplastic properties of adhesive film used for bonding. Five commercial produced fabrics of different structure (woven, knitted, laminate) and fiber content (polyester, cotton, flax) were used in this experiment. Thermoplastic polyurethane film was transferred from the base of silicone to fabric using 160°C temperature and 10 seconds pressing duration. Fabric layers were bonded using 180°C temperature and 30 seconds pressing duration. The strength of textile bonded seams was investigated using four different bond types, in order to determine method suitable for the analyzes of bonded seams of knitted fabrics and method suitable to analyze woven fabrics.

High-strength-high-modulus polyimide (PI) cords reinforced natural rubber (NR) composites are prepared, and the PI cords are treated with resorcinolformaldehyde-latex (RFL) adhesive to enhance the interfacial adhesion with NR matrix. The influence of RFL adhesive variables, such as the ratio of R/F and RF/L, on the adhesion between PI cords and NR is investigated. Furthermore, sorbitol glycidyl ether (SGE) and caprolactam blocked methylene diisocyanate (CBI) are adhered to the surface of the PI cords through a dipcoating procedure to introduce epoxy and NCO groups and graft with more RFL adhesive. The H pull-out force of SGE/CBI-RFL treated PI cords/NR composites reaches as high as 193.9 N, which is 580% higher than that of untreated PI ones. Additionally, the SGE/CBI-RFL treated PI cords/NR composites exhibit superior adhesion, aging, and fatigue resistance together with better mechanical properties as compared with SGE/CBI-RFL treated poly(paraphenylene terephtalamide) (PPTA) cords/NR composites.
