The main development direction of C9 petroleum resin

Modified petroleum resin is not only the development direction of petroleum resin, but also the foothold of many new materials. According to its small production batch, product serialization and roughly the same characteristics of basic raw materials, it is determined that the production of this type of product is mainly intermittent operation. The production of such products can be far away from ethylene production enterprises, and multi-functional production devices and production lines can be constructed according to unit reactions.

On the basis of strong production management, we will develop products required by the market, develop a series of products with a wide range of varieties and strong specificity, and explore new applications in electronic materials, oilfield drilling aids and other new fields. In the future, C9 petroleum resin will adapt to the changing social development according to the following main directions:

① Control the composition of C9 raw materials. The ratio of polymerizable components in the raw materials is adjusted by rough distillation, or pure components or several pure components are added in a certain ratio and mixed and copolymerized to prepare functional resins with special purposes.

②Add polar groups to the distillate to modify. Introducing polar groups to improve the compatibility with other polar compounds and the ability to disperse inorganic fillers can obtain resins with various properties, which can be used as additives for other products to expand the application range of petroleum resins.

③Hydrogenation modification. The original double bond in the resin is destroyed after hydrogenation, and the modified resin is colorless and has no special odor. It can also improve its weather resistance, adhesion, stability and other properties, which further broadens its application fields. This will be the focus of future development in the field of petroleum resins.

④ Strengthen process improvement and develop new processes. If the content of dicyclopentadiene is high, a secondary polymerization process can be used to obtain a resin with better performance.

⑤Strengthen the research on three processes of thermal polymerization, catalytic polymerization and free radical polymerization, complement each other's advantages in the polymerization process, and improve the performance of the resin. It is recommended to use different polymerization processes and control the production process, and adopt different polymerizations in stages.
