Hydrogenation of tackifying resin

Hydrogenation of tackifying resins is an important chemical modification process aimed at improving various properties of the resin by adding hydrogen atoms to the unsaturated double bonds of the resin. The following is a detailed analysis of the hydrogenation of thickening resins:

1.  Purpose and significance of hydrogenation

The main purpose of hydrogenation of tackifying resin is to improve the stability, heat resistance, and aging resistance of the resin. By hydrogenation reaction, unsaturated double bonds in the resin can be eliminated, reducing its reactivity and enhancing the chemical stability of the resin. Meanwhile, the hydrogenated resin can maintain stable performance at higher temperatures, with a slower aging rate and an extended service life.

2.  Types and products of hydrogenation

In the field of hydrogenation of tackifying resins, there are various types of products, such as hydrogenated rosin ester tackifying resins, DCPD hydrogenated resins, etc. These products have their own unique features and are widely used in different fields. For example:

1. Hydrogenated rosin ester thickening resin: such as TR-120S and other models, with high purity, light odor, high adhesion and good stability, especially suitable for plastic ink modification and other fields.

2. DCPD hydrogenated resin: A water white tackifying resin prepared by polymerization and hydrogenation using dicyclopentadiene (DCPD) as the main raw material. It has good tackiness, compatibility, thermal stability, and photostability, and is widely used in rubber, adhesives, printing inks, high-end coatings, hot melt adhesives, and other fields.

3.  Advantages and precautions of hydrogenation

The advantage of hydrogenation of tackifying resin is that it can significantly improve the performance and application value of the resin. Meanwhile, it is also necessary to pay attention to controlling the reaction conditions during the production process to ensure the smooth progress of hydrogenation reaction and stable product quality. Specifically:
1. Advantages: Improve product performance, better environmental performance, and broaden application areas.
2. Precautions: When hydrogenation of thickening resin, it is necessary to strictly control the reaction temperature, pressure, catalyst type, and other conditions. At the same time, strict quality testing is required for the hydrogenated resin to ensure its performance meets relevant standards and requirements.
In summary, hydrogenation of tackifying resins is an important chemical modification method that can significantly improve the performance and application value of resins. With the continuous advancement of technology and the acceleration of industrialization, the hydrogenation of tackifying resin will be widely applied in more fields.
