Using of leather fibers as an additive in elastomeric compounds: Its effect on curing behavior and physico‐mechanical properties

Abstract

In this study, leather fibers have been used as an additive in several elastomeric compounds based on nitryl butadiene rubber (NBR), chloroprene rubber (CR), ethylene-propylene-diene monomer (EPDM), and chlorinated isobutylene-isoprene rubber (CIIR). The effects of employing fibers upon vulcanization characteristics, physico-mechanical and thermal properties of the compounds were studied. Measuring of vulcanization characteristics of the compounds exhibited that leather fibers has no considerable effect on initial viscosity, processability, and curing time of the compounds but increases cross-link density. Evaluation of mechanical properties of the vulcanized compounds showed that using leather fibers leads to increase in tensile strength of NBR-based compound due to compatibility between NBR and leather fibers. Also hardness of all compounds increased drastically by employing leather fibers. The obtained results showed incorporation of leather fibers had no considerable effect on resilience, density, and thermal stability of compounds but enhanced liquid resistance.

Preparation, properties, and characterization of novel fine leather fibers/polyvinyl alcohol composites

“…Furthermore, the chromed leather shavings can be also used to prepare activated carbon , absorbent of pollutions , degreaser , ceramic , etc. By contrast, the researches on incorporating the chromed leather shavings as functional reinforcements in polymer composites have gained much more importance . As the leather fibers have a lot of surface reactive functional groups, compared to the other fibrous reinforcements like plant fiber , glass fiber , and cellulose , the properties of leather‐like composites are expected to be improved greatly.…”

Reciclaje de residuos de cuero: una revisión de estudios experimentales

“…Las fibras de cuero se han utilizado como un aditivo en varios compuestos elastoméricos basados en caucho de nitrilo butadieno (NBR), caucho de cloropreno (CR), copolímeros de etileno-propileno-dieno monómero (EPDM), y caucho de isobutileno-isopreno clorado (CIIR) (Shabani et al, 2009). En este estudio se evaluaron los efectos del empleo de fibras de cuero en las características de vulcanización así como en las propiedades físico-mecánicas y térmicas de los compuestos.…”

“…Durante el proceso se generan gran cantidad de desechos sólidos y líquidos, que debe tratarse adecuadamente para evitar generar alta contaminación ambiental; una de las formas de atenuar el riesgo es la introducción de tecnologías limpias sostenibles (Kanagaraj et al, 2015), o la incorporación de valor agregado a estos residuos (Shabani et al, 2009), siendo este último uno de los principales retos para las curtiembres en el mundo (Cabeza et al, 1998;Rao et al, 2002), y Colombia no es la excepción.…”

The Effect of Leather Fibers on Vulcanization Behavior of Natural Rubber

“…This is not only caused seriously environmental problem but also wasted a large amount of collagen fiber with many valuable features [1][2]. In recent years, using leather solid waste as an ingredient for new materials have received much attention of many research groups [3][4][5]. Leather particles have been used as reinforcements for polymer composite materials to modify physical and mechanical properties such as density, hardness, abrasion resistance, tensile strength, flexibility, process ability and so on.…”
