This paper discusses the curing behaviors, mechanical and dynamical properties of composites containing chloroprene rubber (CR) and butadiene rubber (BR) reinforced with mineral fillers. The iron(III) oxide nanoparticles were used as a crosslinking agent of the CR/BR blends. The research aimed to evaluate the effectiveness of nano-iron(III) oxide (nano-Fe2O3) as a new crosslinking agent while producing elastomeric materials with good mechanical properties and reduced flammability. The CR/BR (chloroprene rubber/butadiene rubber) blends were filled with silicas from natural resources (chalcedony, Neuburg silica earth) or silicas used in elastomer technology in many fields (aerosil, ultrasil). The results revealed that all composites were characterized by satisfactory tensile strength, tear resistance, and high resistance to fire. The filler dispersion in the elastomer matrix was carried out by using scanning electron microscopy (SEM), while the possibility of the filler–filler or filler–rubber interaction in the designed compositions was determined using the Payne effect and the Mullins effect.

Ethylene‐propylene‐diene monomer (EPDM) rubber has widespread uses in various applications due to its ozone and oxidation stability, weatherability, electrical insulation, and elasticity. However, its further use is limited by low flame retardancy and low thermal stability. This study incorporated metal hydroxide flame retardant to enhance flame retardancy and electron beam cross‐linking to simultaneously enhance mechanical properties, thermal stability, and flame retardancy. The utilization of electron beam irradiation resulted in an increase in gel content and a decrease in swelling ratio with increasing absorbed doses, indicating the successful formation of cross‐linked network structures. The hot‐set elongation was significantly reduced to 0.6%–0.8%, while the decomposition temperature increased with increasing absorbed doses, indicating improved thermal stability. The results from limiting oxygen index measurements and burning tests demonstrate that the flame retardancy of EPDM was improved by the combined effect of metal hydroxide flame retardant and electron beam cross‐linking.Highlights EPDM/metal hydroxide composites were prepared via electron beam irradiation. Metal hydroxide flame retardants were incorporated to enhance flame retardancy. EBI simultaneously enhanced mechanical property and thermal stability.

“…Neoprene rubber (CR) is a homopolymer obtained by the emulsion polymerization of 2‐chloro‐1,3‐butadiene. It contains an unsaturated polymer backbone and a large amount of Polarized chlorine 1 . Owing to the reduced activity of double bonds and α‐methylene on the macromolecular chain, CR is generally crosslinked by metal oxides, 2,3 which is different from the crosslinking mechanism of other diene rubbers.…”

CR offers a unique combination of mechanical properties and dynamic deformation and has been widely used in wire and cable sheathing, air springs, oil-resistant rubber products, heat-resistant conveyor belts, road joint sealants, bridge bearings, flame-retardant rubber products, and adhesives.…”

Considering the toxicity of traditional resorcinol‐formaldehyde‐latex (RFL) dipping solution used to prepare fiber‐ reinforced rubber composites, a novel eco‐friendly dopamine (DA)‐supported dipping system was developed in this study. Based on the interactions between DA, glycerol triglycidyl ether (GTE), and m‐xylylenediamine (MXDA), the dipping solution successfully coated the surface of the nylon‐66 (PA66), and the resulting GTE/DA/MXDA/latex‐treated PA66 (PA66‐GDML) possessed better thermal stability than untreated PA66. The interfacial adhesion between PA66 and neoprene was significantly improved by using the appropriate interfacial layer and the synergistic effect during co‐vulcanization. The adhesive strength between PA66‐GDML and neoprene was comparable to that obtained in an RFL system, especially when the ratio of GTE/DA/MXDA was 5:1:2.Highlights An eco‐friendly dopamine‐supported dipping system was developed. The dipping solution (GTE/DA/MXDA) could successfully coat nylon 66 fibers. Treated nylon 66 possessed better thermal stability than untreated nylon 66. The adhesive strength was comparable to that obtained in a RFL system. The new dipping system shows great potential to replace RFL system.
