Description

technical field

[0001] The invention relates to a method for preparing hydrogenated petroleum resin by using dicyclopentadiene as a raw material, in particular to the use of a high-nickel catalyst to remove high-molecular organic sulfur in DCPD resin and the control of the polymerization process to solve the harmful poison of resin hydrogenation, and to prepare high-quality Method for quality hydrogenated petroleum resin. Background technique

[0002] Dicyclopentadiene (DCPD) hydrogenated resin is a high-end product in the petroleum resin industry. It retains the ring structure, and its interaction with the matrix polymer is greater than that of straight-chain aliphatic hydrocarbon resins. Its bonding performance is better than that of ordinary C5 hydrogenated resins. Especially suitable for the field of disposable sanitary materials: food packaging supplies, pressure-sensitive tapes, disposable diapers, women's sanitary napkins and other hot-melt adhesives.
