石油树脂和改性石油树脂的现状及发展建议

目前,全球石油树脂的年产量近80万t。我国生产石油树脂的企业主要有河北四明化工厂、兰州银兰化工厂、靖江溶剂厂、大庆科庆化工厂、山东桐林石油树脂厂、山东琴波化工厂等,大多采用催化法,产量约7万t/a。对石油树脂进行加氢改性、化学接枝改性可提高其性能,这将成为今后的发展方向。我国应充分利用资源优势,解决技术开发、规模化生产、拓展应用领域的问题,以发展石油树脂及改性石油树脂行业。

Status Quo and Development on Petroleum Resin and Modified Petroleum Resin

Currently, the annual world petroleum resin output is nearly 0. 8 million tons. In China, the main producers are Hebei Siming Chemical Plant, Lanzhou Yinlan Chemical Plant, Jingjiang Solvent Plant, Daqing Keqing Chemical Plant, Shandong Tonglin Petroleum Resin Plant, Shandong Qinbo Chemical Plant, etc. . Most of them adopt catalytic method, the combined output is about 70000t/a. Hydrogenation modification or chemical graft modification can improve petroleum resin properties, therefore, this will be the development direction for the future. China should make the best of resource advantage and solve the problems of technical development, scale production, widening application fields so as to develop petroleum resin and modified petroleum resin industry.
