Plastic Wood Composite Resistance · Recycled by the Addition of UV Stabilizer to the Weather

Introduction

The use of plastic composite (Wood Polymer Composite/WPC) has become increasingly widespread in recent years. Not only is it used for indoor products such as floors, house walls, and furniture, but it is also widely used outdoors, including boat decks, hulls, and roofs of houses. However, the use of WPC in outdoor environments poses several challenges, particularly in terms of material endurance. Some of the problems faced include heat stability, fungal resistance, changes in shape due to absorption of water vapor, and resistance to ultraviolet (UV) rays.

The Importance of UV Stabilizer in Plastic Wood Composite

The main purpose of this study is to evaluate the effect of the addition of UV stabilizer on the resistance of plastic recycled plastic wood when exposed to weather. This study involved 12 treatments consisting of two main factors: the addition of maleat anhydride (Mar) and UV stabilizer, with each treatment repeated three times. The Mar factor has two levels, namely 0% and 2.5%, while the UV Stabilizer factor has six levels, namely concentrations of 0%, 1%, 2%, 3%, 4%, and 5%.

Methodology

After the manufacturing process, the recycled plastic composite sheet was presented on the weather for six months. The tests carried out included changes in color and mechanical properties such as tensile strength, young modulus, and breakfall elongation. For more in-depth analysis, observations were made using Electron Microscope (SEM) scanning to assess changes in composite surface and Fourier Transform Infrared Spectroscopy (FTIR) to detect changes in carbonyl groups.

Results

The results showed that the addition of Mar and UV Stabilizer did not significantly reduce the level of discoloration in composite. However, the addition of Mar has a significant effect on the tensile strength and modulus of Young composite after six months of exposure. Meanwhile, the addition of UV Stabilizer did not show a significant effect. Both have a real impact on broken elongations, but only on composite that are not exposed to weather; In composite exposed for six months, the influence is not visible.

Analysis through SEM and FTIR

Analysis through SEM reveals that the addition of mah and UV stabilizer can increase the bond between wood and plastic powder, and maintain composite structures despite having experienced a long weather exposure. Meanwhile, the results of FTIR testing show that the two additions can reduce the oxidation process that occurs due to exposure, which is reflected in the lower carbonyl index.

Conclusion

Thus, this research provides a better understanding of WPC resistance to hard environmental conditions and strengthens the need to use the right addition so that the composite of plastic recycled plastic can be used optimally in outdoor applications. This certainly has major implications for the construction industry and building materials, where durability and sustainability are the key in the selection of materials.

The Future of Plastic Wood Composite

The use of plastic wood composite is expected to continue growing in the coming years, driven by its durability, sustainability, and aesthetic appeal. However, the challenges posed by outdoor exposure must be addressed through the use of UV stabilizers and other additives. This research provides valuable insights into the effects of UV stabilizers on the resistance of plastic wood composite, and highlights the need for further research in this area.

Recommendations

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

The use of UV stabilizers should be considered when designing and manufacturing plastic wood composite products for outdoor use.
Further research is needed to investigate the effects of different types and concentrations of UV stabilizers on the resistance of plastic wood composite.
The use of maleat anhydride (Mar) should be considered as a potential additive to improve the tensile strength and modulus of Young composite.

Limitations of the Study

This study has several limitations, including:

The study was conducted over a period of six months, which may not be sufficient to fully assess the effects of UV stabilizers on the resistance of plastic wood composite.
The study only investigated the effects of UV stabilizers on the mechanical properties of plastic wood composite, and did not consider other factors such as color stability and fungal resistance.

Future Research Directions

Future research should focus on investigating the effects of different types and concentrations of UV stabilizers on the resistance of plastic wood composite, as well as exploring the use of other additives to improve the durability and sustainability of plastic wood composite products. Additionally, research should be conducted to investigate the effects of UV stabilizers on the color stability and fungal resistance of plastic wood composite.

Conclusion

In conclusion, this research provides valuable insights into the effects of UV stabilizers on the resistance of plastic wood composite, and highlights the need for further research in this area. The use of UV stabilizers is expected to continue growing in the coming years, driven by its durability, sustainability, and aesthetic appeal. However, the challenges posed by outdoor exposure must be addressed through the use of UV stabilizers and other additives.
