Embodiment 1～6

[0081] The following table 9 is the embodiment of preparing C5 / C9 petroleum resin, raw material C is Pd / Al 2 o 3 The processes of catalyst selective hydrogenation, Friedel-Crafts catalyst pretreatment and subsequent catalyst removal, raw material rectification to remove oligomers, solvent dilution, and resin polymerization liquid catalyst removal are as follows:

[0082] (1) Thermal prepolymerization

[0083] Mix the raw materials A, B, and D to obtain the polymerization raw material E, and then transport it to a high-pressure reactor with stirring for thermal prepolymerization to obtain the dimerization product F of carbopentaolefins and styrene or methylstyrene;

[0084] (2) Catalytic polymerization

[0085] The above-mentioned dimerization product F is used as raw material, mixed with a solvent at a mass ratio of 1:0.1~1.0, and a gaseous boron trifluoride catalyst is added to catalyze polymerization to obtain a dark yellow to brown polymerization liquid, which is a mixtur...

Abstract

The invention relates to a method for preparing C5 / C9 copolymerized petroleum resin. The method comprises the following steps of: mixing crude m-pentadiene, crude cyclopentadiene and selectively hydrogenated and pretreated C9 material D uniformly, performing pre-polymerization at the temperature of between 180 and 230 DEG C to obtain a dimmer mixture F of C10 and C15, blending hydro-cracking aviation kerosene serving as a solvent, performing catalytic polymerization for 2 to 5 hours at the temperature of between 30 and 65 DEG C by using gaseous boron trifluoride as a catalyst to obtain deep yellow to brown polymerization solution, rectifying under reduced pressure to remove the solvent and oligomers, and thus obtaining the C5 / C9 copolymerized petroleum resin. The prepared C5 / C9 resin is good in compatibility and light in color; the preparation method is reasonable and strong in pertinence; the hue, the compatibility and the thermal stability of the resin are remarkably improved; and the resin can be widely applied in the fields of ink, coating, papermaking, plastics and the like.

Description

technical field [0001] The invention belongs to the field of petroleum resin modification, in particular to a preparation method of C5 / C9 copolymerized petroleum resin. Background technique [0002] Petroleum resin is a solid or viscous liquid polymer with relatively low molecular weight, which is obtained by polymerizing the by-product C5 / C9 fraction of the ethylene plant as the main raw material. It has the characteristics of low acid value, good miscibility, low melting point, good adhesion, water resistance and chemical resistance. At present, it has been widely used in road marking paint, ink, rubber processing, adhesives and other fields. According to the monomer and molecular structure of the resin, it can be divided into aromatic petroleum resin, aliphatic petroleum resin and alicyclic petroleum resin. [0003] C9 petroleum resin is a kind of aromatic petroleum resin, which is polymerized from ethylene by-product C9 as a raw material. C5 petroleum resin is an import...
