“…As it can be seen in Table 3, the DM decreased significantly after the addition of modified kaolinite, mainly in relation to the Ni/8 and it could be attributed to the aggregation of particles on the surface of kaolinite. Thus, the tendency of M H lowering can be assigned to the higher loading of modified kaolinite and could be attributed to the filler aggregation [45].…”

Effect of kaolinite modified with Cu(II), Co(II) and Ni(II) salts as a partial replacement for carbon black (1 and 8 phr) on the properties of the model tread rubber blend was examined. The blends were prepared in a two-stage process in a Brabender mixer at temperatures of 120°C and 100°C, respectively, with a constant mixing speed of 50 rpm. FT-IR confirmed the formation of copper hydroxyacetate monohydrate complex, which may indicate chemical interactions between rubber components and modified kaolinite. The filler improved technological parameters, tensile properties and hardness. Resistance to thermal aging has also increased.

“…The abundant natural reserves and low acquisition cost of kaolinite provide an easy foundation for the industrialization of such composites with the cost being only about a quarter of that of montmorillonite/polymer nanocomposites. Therefore, research into kaolinite/polymer nanocomposites has attracted attention in recent years [7][8][9] . Due to the unique layered structure of inorganic silicates and the common compatibility issues between inorganic and organic components, direct one-step compounding is challenging to achieve.…”

Polyurethane foam insulation materials exhibit excellent noise reduction, shock absorption and vibration damping capabilities while being cost-effective and easily moldable. They have found widespread applications in diverse fields such as automotive, machinery, packaging, insulation, healthcare and construction. However, the application range of this traditional organic material is limited by issues related to thermal stability and flame retardancy. By achieving uniform dispersion of nanoparticles, composite materials exhibit enhanced comprehensive properties in terms of flame retardancy, oxidation resistance, physicochemical stability and structural performance. Polyurethane/Kaolinite nanocomposite insulation materials were prepared by using the in situ intercalation compounding method. X-ray diffractometer, Fourier infrared spectrophotometer, thermogravimetric analyzer and scanning electron microscope were used to characterize the thermal stability of the composite material obtained under different preparation conditions and the state of the nanomaterial in the system. The results showed that the composite material with good dispersion of kaolinite in the matrix was obtained by effective surface modification through dimethyl sulfoxide. The doping of low-concentration kaolinite can improve the thermal stability of polyurethane. When the mass fraction of nano-kaolinite is 5%, the initial decomposition temperature of the composite system is 47°C higher than that of pure polyurethane and the system achieves the highest thermal stability.

“…Natural rubber (NR), as an extremely important strategic resource, has been widely applied in tires and conveyor belts for the transportation, aerospace, construction [1][2][3][4][5]. The unique strain induced crystallization ability can endow it with the excellent mechanical strength, wear resistance, high elasticity and other characteristics [6][7][8][9]. However, the relatively short fatigue lives of NR-based composites still limit its further practical applications.…”

Herein, the carbon black/graphene oxide/natural rubber composites (CB/GO/NR) with different crosslink networks were prepared through the latex co-precipitation approach. Meanwhile, the type of crosslinks on the crack propagation resistance and fatigue life in different vulcanized systems were investigated. As a result, CB/GO/NR composites dominated by polysul de in conventional vulcanization (CV) system exhibited the improved tear strength (71.6 KN/m) and lowest crack growth rate (64.1 nm/cycle), the developed crosslink network and polysul de based crosslink structure in CV system were the key factors to improve the crack propagation resistance. In addition, the relationship between viscoelasticity and dynamic crack propagation behavior of CB/GO/NR was studied, and the CV system had the lowest loss compliance modulus( J "), thus more energy dissipation occurred in the crack propagation region and the crack propagation resistance of CV system was improved. Importantly, this work can provide the guideline for designing the rubber-based composites in the practical engineering applications.
