Study on Possible Application of Rubber Granulate from the Recycled Tires as an Elastic Cover of Prototype Rail Dampers, with a Focus on Their Operational Durability

This study is an attempt to investigate possible applications of rubber granulate SBR (styrene-butadiene rubber) produced from recycled waste tires as an elastic cover for prototype rail dampers, which are aimed at reducing the level of railway noise emitted in the environment. The authors present laboratory procedures and discuss the results of several experimental tests performed on seven different SBR materials with the following densities: 1100, 1050, 1000, 850, 750, 700 and 650 kg/m3. It is proven that rubber granulate SBR produced from recycled waste tires, can be used as an elastic cover in steel inserts in rail dampers, provided that the material density is not lower than 1000 kg/m3. In the conducted tests, samples of the materials with high densities exhibited good static and dynamic elastic characteristics and had sufficient operational durability.

Only a few works focus on the use of commercial pyrolysis carbon black (PCB) to replace with commodity carbon black in terms of increasing environmental awareness. In this work, a commercial PCB (ET (Enrestec) black) from waste tires was compared with N660 carbon black in styrene–butadiene rubber (SBR) compounds using standard American Society for Testing and Materials recipes. Particle aggregate size, composition, and surface functionality of ET black and N660 were analyzed through light scattering, energy-dispersive X-ray spectroscopy (EDS), and Fourier transform infrared spectroscopy, respectively. Higher compound viscosity and aggregation power for ET black filler in the rubber matrix was observed. A progressive decrement of approximately 20% in M300 from 15.2 MPa for N660-filled SBR to 12.4 MPa for ET black-filled SBR with increasing ET black ratio in the fillers was clearly observed. ET black could potentially replace 20% in N660 without much influence for SBR compounds in terms of tensile strength. The effect of ET black content on the tear strength was less marginal than the tensile strength. However, with increasing the ET black content, the abrasion resistance index progressively decreased. Thus, it was quite beneficial to consider the merit of PCB in terms of the applications required for tearing resistance. This paves the way for the opportunities to expand further commercial application of PCB from waste tires in the light of environmental awareness.

Improper disposal and storage of waste tires poses a serious threat to the environment and human health. In light of the drawbacks of the current disposal methods for waste tires, the transformation of waste material into valuable membranes has received significant attention from industries and the academic field. This study proposes an efficient and sustainable method to utilize reclaimed rubber from waste tires after devulcanization, as a precursor for thermally rearranged (TR) membranes. The reclaimed rubber collected from local markets was characterized by thermogravimetric analyzer (TGA) and Fourier transfer infrared spectroscopy (FT-IR) analysis. The results revealed that the useable rubber in the as-received sample amounted to 57% and was classified as styrene–butadiene rubber, a type of synthetic rubber. Moreover, the gas separation measurements showed that the C7-P2.8-T250 membrane with the highest H2/CO2 selectivity of 4.0 and sufficient hydrogen permeance of 1124.61 GPU exhibited the Knudsen diffusion mechanism and crossed the Robeson trade-off limit. These findings demonstrate that reclaimed rubber is an appealing, cost effective, and sustainable alternative, as a precursor for TR membranes, for application in gas separation. The present approach is useful in the selection of a suitable reclaimed rubber precursor and related membrane preparation parameters, leading to the advancement in the recycling value of waste tires.
