    • PURPOSE: Provided are a petroleum co-polymer resin and its preparation method for a hot-melt, pressure hot-melt and solvent pressure adhesives. The characteristic point of this resin is that it does not need the separation equipment for isoprene because mixed C5 oil is used in the production process. The resin has compatibility with base polymer, 180 degree stripping strength and strong adhesiveness. CONSTITUTION: The resin is prepared by mixing 20-40wt.% of mixed C5 oil comprising isoprene, piperylene, cyclopentadiene, 1-pentene, 2-methyl-2-butene and n-pentane; 20-40wt.% of mixed C9 oil comprising styrene, vinyltoluene, indene, α -methylstyrene and BTX and 20-60wt.% of dicyclopentadiene and carrying on thermal polymerization at 250-300deg.C for 2-6 hours and hydrogenating this co-polymer at 130-250deg.C under 50-80 atmosphere pressure.
    • 目的:提供一种石油共聚树脂及其制备方法,用于热熔,压力热熔和溶剂压力粘合剂。 该树脂的特征在于,其不需要用于异戊二烯的分离设备,因为在生产过程中使用混合的C5油。 该树脂与基础聚合物相容,180度剥离强度和强粘合性。 构成:通过混合20-40重量%的包含异戊二烯,戊间二烯,环戊二烯,1-戊烯,2-甲基-2-丁烯和正戊烷的混合C5油来制备树脂; 20-40重量%的包含苯乙烯,乙烯基甲苯,茚,α-甲基苯乙烯和BTX的混合C9油和20-60重量%的二环戊二烯,并在250-300℃下进行热聚合2-6小时, 聚合物在130-250℃在50-80大气压下。
