Introduction

The increasing demand for sustainable and environmentally friendly materials has led to the development of new technologies and processes that can reduce waste and minimize the environmental impact of production. One such area of research is the use of recycled materials as fillers in polymer composites. In this study, we investigate the characterization of EPDM/NR (Ethylene Propylene Diene Monomer/Natural Rubber) alloy reinforced with used tire powder as a filler, produced using a single screw extruder.

The Process of Making and Characterizing Initial EPDM/NR Alloy

The process of making EPDM/NR alloys begins with EPDM and SIR-20 vulcanization using stearic acid, ZnO, MBTS, and sulfur at 170 ° C using extruders. Vulcanization results are then pressed using a hot press at 140 ° C to produce an EPDM/NR alloy. In the initial stages, a tensile test on the EPDM/NR alloy was carried out with a composition variation of 70:30. The results showed the tensile strength of 0.34 MPa, strain 99.66%, and modulus of elasticity (MOE) of 0.341 MPa. Functional group analysis using FTIR (Fourier Transform Infrared Spectroscopy) is carried out to study the chemical structure of the alloy.

The tensile test results indicate that the EPDM/NR alloy has a relatively low tensile strength and high strain, which suggests that it may not be suitable for applications that require high mechanical strength. However, the results also show that the alloy has a high modulus of elasticity, which indicates that it may be suitable for applications that require high stiffness and resistance to deformation.

Effect of Additional Tire Powder

To increase the characteristics of the material, the optimized EPDM/NR alloy is then mixed with used tire powder with a variety of additional 10 PHR, 20 PHR, and 30 PHR. The addition of this used tire powder produces an EPDM-NR-Serbuk used tire composite.

The addition of used tire powder to the EPDM/NR alloy is expected to improve its mechanical properties, such as tensile strength and impact resistance. The used tire powder is also expected to reduce the cost of production and minimize waste.

Characterization of EPDM-NR-Serbuk Used Tire Composite

EPDM-NR-Serbuk used tire composites are characterized through the impact strength test, SEM (Scanning Electron Microscopy), and DSC (Differential Scanning Calorimetry). The impact strength test results show that composite with the addition of used tire powder of 20 PHR has the highest impact strength value, which is 8,2369 J/m².

The impact strength test results indicate that the addition of used tire powder to the EPDM/NR alloy improves its impact resistance. The composite with 20 PHR of used tire powder has the highest impact strength value, which suggests that this composition may be suitable for applications that require high impact resistance.

SEM Analysis

SEM analysis shows that the composite mixture looks homogeneous, shows a good distribution of used tire powder in the EPDM/NR matrix. The SEM images also show that the used tire powder is well dispersed in the EPDM/NR matrix, which suggests that the composite has a good mechanical properties.

DSC Analysis

DSC results show that composite decomposes at the exothermic peak reaches a temperature of 439.62 ° C. The DSC analysis indicates that the composite has a high thermal stability, which suggests that it may be suitable for applications that require high thermal resistance.

Analysis and Implications

The use of used tire powder as a filler in the EPDM/NR alloy shows a significant potential in reducing tire waste and improving the mechanical properties of the material. The addition of used tire powder to certain compositions can increase the power of impact and maintain material homogeneity.

The results of this characterization indicate that used tire powder can be used as an effective filler to produce composite with good mechanical properties. The study also suggests that the EPDM/NR alloy reinforced with used tire powder has the potential as material with good mechanical properties and environmentally friendly.

Conclusion

This study shows that the EPDM/NR alloy which is reinforced with used tire powder has the potential as material with good mechanical properties and environmentally friendly. The characterization of composite with various techniques such as tensile testing, the impact strength test, SEM, and DSC provides a deep understanding of the effect of used tire powder on material properties.

Further research can be carried out to optimize the composition of used tire powder and study its influence on other material properties such as resistance to wear and thermal properties. The study also suggests that the use of used tire powder as a filler in the EPDM/NR alloy has a significant potential in reducing tire waste and improving the mechanical properties of the material.
