Modification of the Surface of the Palm Oil Bunches with Acetate Anhydride as a Polypropylene Filler Material

Introduction

The palm oil industry is one of the largest industries in the world, with millions of tons of palm oil being produced every year. However, the production process generates a significant amount of waste, including empty palm bunches. These empty palm bunches are abundant and have great potential as a source of cellulose fiber, which can be processed into pulp and used as a filler in making polypropylene. The use of cellulose fiber as a filler in polypropylene can increase its mechanical strength, making it a valuable material in various industrial applications.

However, the difference in polarity between cellulose and polypropylene becomes an obstacle in the compatibility of the mixture. To overcome this, chemical modification is needed to reduce cellulose polarity, one of which is by acetylation. Acetylation is a process that involves the reaction of cellulose with acetic anhydride, resulting in the formation of acetyl groups on the surface of the cellulose fibers. This modification can reduce the polarity of cellulose, making it more compatible with polypropylene.

Surface Modification of Palm Oil Bunches with Acetate Anhydride

This study examines the surface modification of the palm oil bunch powder surface with acetylation. The process involves initial treatment with perchlorate acid at 60 ° C for 2 hours, 80 ° C and 100 ° C for 1 hour to prepare cellulose fibers. The results of FT-IR and DTA analysis show that acetylation is successfully carried out, with a hydroxyl group in modified cellulose chains, especially on the surface of the pulp powder.

The FT-IR analysis shows that the absorption of the hydroxyl group in the modified cellulose chains is increased, indicating the formation of acetyl groups on the surface of the cellulose fibers. The DTA analysis shows that the thermal stability of the modified cellulose fibers is increased, indicating that the acetylation process has improved the thermal stability of the cellulose fibers.

Effect of Surface Modification on Compatibility and Performance

The surface modification of the palm oil bunch powder with acetylation has a positive impact on the compatibility of the mixture of polypropylene-pulp empty palm oil. A mixture with a pulp that has been deleted (ratio 60/40) shows a significant increase in tensile strength compared to a mixture that uses pulp without modification. This indicates that acetylation increases the interaction between the filler and the polypropylene matrix.

The SEM photo shows the distribution of equitable fillers in the polypropylene matrix. The photo shows that the fillers are evenly distributed in the matrix, indicating that the surface modification has improved the compatibility of the mixture.

Analysis of FT-IR and DTA

The FT-IR analysis of the polymer mixture shows that there is no significant change in the absorption of the carbonyl group, which indicates the physical interaction between the polypropylene matrix and the filler. The DTA analysis shows that the thermal stability of the polymer mixture is increased, indicating that the surface modification has improved the thermal stability of the mixture.

Conclusion

The surface modification of the oil palm empty pens powder through acetylation is proven effective in increasing the compatibility and performance of the polypropylene mixture. This opens opportunities for the use of oil palm empty bunches into high quality fillers in various industrial applications, while reducing environmental impacts.

Future Work

The use of acetylation as a surface modification technique has shown promising results in improving the compatibility and performance of the polypropylene mixture. However, further research is needed to explore the potential of this technique in other industrial applications. Additionally, the optimization of the acetylation process and the characterization of the modified cellulose fibers are necessary to improve the quality and consistency of the filler material.
