Petroleum resin can be widely used in various industries,Petroleum Resin such as paint, rubber, etc. Why is petroleum resin so popular?
There are two main ways of modification. One is hydrogenation modification,Petroleum Resin which adds the double bond in the petroleum resin molecule,Petroleum Resin thereby improving its color and anti-oxidation stability. Petroleum resins with special properties can be prepared by adding polar groups or modifiers such as monoolefin to the raw materials.
The cracked C9 fraction mainly contains unsaturated aromatic hydrocarbon compounds such as vinyl toluene, indene, methylstyrene,Petroleum Resin etc.
The preparation process of C9 petroleum resin is as follows: the raw materials are pretreated to remove (bis) cyclopentadiene and isoprene,Petroleum Resin to obtain raw materials with a mass fraction of more than 50%,Petroleum Resin and then add a diluent aromatic hydrocarbon under the protection of nitrogen,Petroleum Resin Then add the catalyst AlCl3.
The development status of C9 petroleum resin production at home and abroad: the development of petrochemical industry provides rich and cheap raw materials for the production of petroleum resin,Petroleum Resin so the production of petroleum resin in some petrochemical developed countries is developing rapidly.
C9 petroleum resin is a thermoplastic resin produced by cracking the by-product C9 fraction of ethylene production unit as the main raw material,Petroleum Resin polymerizing it in the presence of a catalyst,Petroleum Resin or copolymerizing it with aldehydes, aromatic hydrocarbons, terpenes. Its molecular mass is generally less than 2000,Petroleum Resin softening point is less than 150 ℃, Petroleum Resin it is a thermoplastic viscous liquid or solid.
