Study of Elastomer Thermoplastic Making and Characterization of Polypropylene-Caret Ethylene Propylene Diene Monomer-Leb Tires With the Addition of Dicred Peroxide and Divinilbenzene

Introduction

In recent years, the world has witnessed a significant increase in the production of waste materials, particularly in the form of used tires. The disposal of these tires poses a significant environmental challenge, as they contribute to pollution and waste management issues. In an effort to create sustainable new materials, a study has been carried out on the manufacture and characterization of elastomer thermoplastic from a mixture of polypropylene and rubber ethylene propylene diene monomer (EPDM) mixed with used tire ash. This study also involved the addition of dicred peroxide (DCP) as an initiator and divinilbenzene (DVB) as a liaison agent.

Background

The use of used tire ash in the production of elastomer thermoplastic is a promising approach to waste recycling and sustainable material development. Used tire ash is a byproduct of tire pyrolysis, which involves the thermal decomposition of tires in the absence of oxygen. The resulting ash is rich in carbon and can be used as a filler material in the production of elastomer thermoplastic. The addition of DCP and DVB to the mixture is expected to enhance the crosslinking process and improve the mechanical properties of the material.

Materials and Methods

The manufacturing process begins by mixing polypropylene, EPDM rubber, and used tire ash with a weight ratio of 50:25:25 g. Variations in adding DCP and DVB are carried out with a number of 1 PHR, 2 PHR, and 3 PHR, then mixed in an internal mixer at 175 ° C. After mixing, the specimen is pressed at the same temperature and is formed according to the ASTM D638 standard.

Analysis of the Results of Making

This study emphasizes the characterization of the material produced based on several parameters, including tensile strength, percentage of gel, mixture surface morphology, and functional group analysis. The results obtained indicate that the addition of DVB to the mixture increases the strength of the tensile significantly compared to the mixture without DVB. The tensile force value for the mixture with DVB reaches 1.79 kgf/mm², while for the mixture without DVB only 1.52 kgf/mm².

Gel Content and Morphology

In the case of content gel, a mixture with the addition of DVB shows a higher percentage of gel, which is 87.8%, compared to 86.3% on the mixture without DVB. This increase in content gel shows that DVB plays an important role in the crosslinking process, which results in better mechanical strength and material stability.

Morphological results show that the surface of the mixture without DVB contains more and is greater void compared to a mixture containing DVB. The existence of this void can indicate the lack of interaction between molecules in the mixture, which can affect the functional properties of the elastomer produced. Thus, the addition of DVB does not only have an impact on tensile strength, but also on morphological characteristics, which in turn affects the performance of materials in practical applications.

Conclusion

This study provides valuable insights about the potential use of used tire ash in making elastomer thermoplastic, especially with the addition of connecting agents such as DVB and initiator such as DCP. By increasing the tensile strength and stability of the material, this research opens the way for the development of more sustainable and efficient material solutions, while making a positive contribution to the environment through waste recycling. Thus, this material not only meets the technical criteria needed in industrial applications, but also plays a role in environmental mitigation efforts.

Future Directions

The results of this study suggest that the use of used tire ash in the production of elastomer thermoplastic is a promising approach to waste recycling and sustainable material development. However, further research is needed to optimize the manufacturing process and to explore the potential applications of this material. The use of DVB and DCP as connecting agents and initiator, respectively, has been shown to enhance the crosslinking process and improve the mechanical properties of the material. However, the effects of these additives on the material's thermal stability and resistance to degradation need to be investigated further.

Recommendations

Based on the results of this study, the following recommendations are made:

Optimization of the manufacturing process: The manufacturing process needs to be optimized to improve the quality and consistency of the material produced.
Exploration of potential applications: The potential applications of this material need to be explored, including its use in the production of tires, belts, and other rubber products.
Investigation of the effects of additives: The effects of DVB and DCP on the material's thermal stability and resistance to degradation need to be investigated further.
Development of new materials: The development of new materials using used tire ash and other waste materials needs to be explored.

Limitations

This study has several limitations, including:

Limited scope: The study was limited to the characterization of the material produced using used tire ash and the addition of DVB and DCP.
Small sample size: The sample size was small, which may not be representative of the material produced on a larger scale.
Limited testing: The testing was limited to the characterization of the material's mechanical properties, and further testing is needed to explore its thermal stability and resistance to degradation.

The results of this study suggest that the use of used tire ash in the production of elastomer thermoplastic is a promising approach to waste recycling and sustainable material development. However, further research is needed to optimize the manufacturing process and to explore the potential applications of this material.
