Introduction

Petroleum resin is a commonly used thickening agent that imparts adhesive properties to products such as tapes, coatings, inks, rubber, and tires. It can exist as a liquid or solid thermoplastic resin at room temperature, with various forms ranging from semi-fluid and transparent to pale yellow or colorless solid. The manufacturing process of petroleum resin typically involves polymerizing C5 or C9 diene hydrocarbon oils with catalysts, by catalyst removal, washing, and resin separation. In recent years, alternative polymerization methods like thermal and free radical polymerization have been employed to improve resin performance. Hydrogenated petroleum resin, derived from high-level unsaturated hydrocarbons found in high-temperature pyrolysis oils like petroleum naphtha, is a thermoplastic resin known for its excellent stability against heat and ultraviolet (UV) radiation. It offers exceptional adhesive properties and finds diverse applications in medical supplies, woodworking products, hygiene items, and more.

Enhancing Performance

During the production of hydrogenated petroleum resin, it can be challenging to completely remove unreacted raw materials, solvents, and low-molecular-weight oligomers. However, using thermal polymerization instead of complex catalytic polymerization in the hydrogenation process can yield significant improvements. By incorporating cyclic diolefins, such as dicyclopentadiene, as raw materials along with olefin monomers as co-monomers, the resulting hydrogenated petroleum resin exhibits enhanced adhesion and thermal resistance. This process also helps improve the resin's odor. When applied as an adhesive, the performance of hydrogenated petroleum resin is further enhanced.

Advantages of Hydrogenated Petroleum Resin

1. Superior Stability: Hydrogenated petroleum resin demonstrates outstanding stability against heat and UV radiation. This property ensures that products incorporating the resin maintain their adhesive strength and structural integrity even under challenging environmental conditions.

2. Enhanced Adhesion: The use of hydrogenated petroleum resin improves the adhesion properties of various products such as tapes, coatings, and adhesives. The resin's cohesive nature promotes strong bonding between different surfaces, enhancing overall product performance.

3. Wide Range of Applications: The versatility of hydrogenated petroleum resin enables its utilization in diverse industries. It finds applications in medical supplies, woodworking products, hygiene items, and other areas where adhesion, thermal stability, and reliable performance are crucial.

Conclusion

Hydrogenated petroleum resin is a valuable adhesive material known for its ability to enhance adhesion and thermal stability. With its exceptional resistance to heat and UV radiation, this resin is well-suited for applications in industries ranging from medical to woodworking. By incorporating cyclic diolefins and olefin monomers in the polymerization process, the resulting resin exhibits improved adhesion strength, thermal resistance, and reduced odor. The continuous development and utilization of hydrogenated petroleum resin contribute to advancements in various products, ensuring their durability and reliable performance.
