Abstract

The invention provides a production method of petroleum resin, mainly comprising the following steps: using C5 fraction and / or C9 fraction of petroleum hydrocarbon cracking as material, and producing the finished product of petroleum resin by pre-processing, polymerizing, post-processing and fine-forming, wherein the polymerization is as follows: mixing the material and solvent as a mixture, continuously conveying the mixture into a polymerization reactor while continuously adding the catalysis into the same, equably mixing the catalysis with the mixture, polymerizing for 1-5h and leading thepolymerization product out, and performing continuous catalysis polymerization reaction. The production method of petroleum resin uses continuous production process, thereby guaranteeing stable and consistent property indexes (chromaticity, softening point, and the like) of the product in the same type number; the preparation of materials can be flexibly changed, thereby enlarging the applicationrange and realizing industrialization.

Description

technical field

[0001] The present invention relates to a kind of technology of producing petroleum resin, specifically, relate to a kind of petroleum resin production method of continuous operation. Background technique

[0002] Petroleum resin has the advantages of low price, good miscibility, low melting point, water resistance, ethanol and chemical resistance, and can be widely used in various industries and fields such as rubber, adhesives, coatings, papermaking, and inks. Since the main raw material of petroleum resin is the C5 and C9 fractions of the by-products of petroleum hydrocarbon cracking to produce ethylene, the effective utilization of petroleum resin has become an important issue for the rational use of petroleum resources and the reduction of ethylene production costs.

[0003] At present, the production process of petroleum resin in developed countries in the world is developing in the direction of continuous scale large-scale, variety diversification, and...
