The Influence of the Concentration of Ammonium Laurat on Tensile and External Strength and Tear Resistance of Natural Rubber Latex Films

Introduction

Natural rubber latex (NRL) is a versatile material widely used in various industries, including automotive, consumer products, and medical applications. The mechanical properties of NRL films, such as tensile strength, purity, and tear resistance, play a crucial role in determining their performance and durability. In recent years, the addition of ammonium laurat (AL) has been explored as a means to enhance the mechanical properties of NRL films. However, the optimal concentration of AL required to achieve the desired properties remains unclear. This study aims to investigate the effect of AL concentration on the mechanical properties of NRL films using the immersion method.

The Effect of Ammonium Laurat Concentration on Tensile Strength, Purity, and Tear Resistance of Natural Rubber Latex Films

In this study, we investigated the effect of AL concentration on the mechanical properties of NRL films using the immersion method. The concentration of AL used varies, which is 0%; 0.05%; 0.07%; and 0.09%. The vulcanization process is carried out for 30 minutes at 100 °C. We analyze the physical properties of the latex film produced, including tensile strength, purity, and tear resistance, and examine surface structures using an analysis of Electron Microscope (SEM) scanning analysis.

Results and Discussion

From the experimental results, it was found that the concentration of AL had a significant impact on the mechanical properties of NRL films. At a concentration of 0.05%, latex film shows the strength of the maximum tensile and tear resistance. This may be caused by the ability of AL in increasing the bond between latex molecules, thus providing better structural stability in the film produced.

However, for the best power, latex films at a concentration of 0.07% show better results. This increase in purity can be associated with the AL which provides a balance between strength and flexibility. At a higher concentration, the saturated effect can result in a decrease in mechanical properties, which explains why a 0.09% concentration does not provide optimal results.

SEM Analysis

SEM analysis provides deeper insight into the surface structure of latex films. At a concentration of 0.05%, the surface of the film looks smoother and more uniform, shows that the ammonium particles of laurat are distributed evenly. Meanwhile, at a concentration of 0.07%, although the best stubbornness is obtained, there are some inequality that may be caused by the interaction between latex molecules and more complex laurate ammonium.

Mechanisms of Ammonium Laurat on Natural Rubber Latex Films

The addition of AL to NRL films can be attributed to its ability to form a complex with latex molecules, thereby increasing the bond between them. This complexation reaction can lead to an improvement in the mechanical properties of NRL films, including tensile strength, purity, and tear resistance. The optimal concentration of AL required to achieve the desired properties is believed to be around 0.05%, as this concentration provides the maximum tensile strength and tear resistance.

Conclusion

From this study, it can be concluded that there is a direct relationship between the concentration of AL and the mechanical properties of NRL films. The 0.05% concentration produces maximum tensile strength and tear resistance, while a 0.07% concentration provides the best stubbornness. This study shows that the selection of exact concentrations of AL is very important to improve the quality of NRL films, which can be applied in various industries, ranging from automotive to consumer products. By understanding the interaction between these additives, we can develop latex films that are more efficient and high quality.
