Abstract

The invention relates to a method for catalyzed preparation of C5 petroleum resin by utilizing boron trifluoride. The method comprises the steps of rectifying C5 fractions to obtain a polymerization raw material A with a boiling point of 20-70 DEG C, causing enriched materials of styrene, alpha-methyl styrene and vinyl toluene to serve as a polymerization raw material B, evenly mixing the raw material A, the raw material B and saturated varsol according to a mass ratio of 1:(0-0.5):(1-1.5) to obtain ingredients; reacting for 2-5 h at 50-170 DEG C under the effect of a Friedel-Crafts catalyst of a BF3 system, and obtaining polymerization liquid; and obtaining the modified C5 petroleum resin through solvent removal and oligomer removal. The method is simple and convenient in process, the adaptability to complex C5 raw materials is good, and the C5 petroleum resin with a high softening point can be prepared.

Description

technical field [0001] The invention belongs to the field of petroleum resin preparation, in particular to a method for preparing C5 petroleum resin by boron trifluoride catalysis. Background technique [0002] C5 petroleum resin, also known as aliphatic petroleum resin, is a medium and low molecular weight polymer obtained by cationic catalytic polymerization with the C5 fraction of ethylene by-product as raw material, and its number average molecular weight (Mn) is 300-3000. C5 petroleum resin has the characteristics of low acid value, good miscibility, water resistance, ethanol resistance and chemical corrosion resistance, and can improve adhesive performance, so it is widely used in rubber and adhesive tackifiers and high solid content coatings, transportation Paint, ink, paper and other industries. [0003] In recent years, with the development of the field of petroleum resins, C5 petroleum resins have been modified or mixed in different ways to obtain various new type...
