Abstract

The invention discloses a synthesizing method of oil resin, which comprises the following steps: adopting C10, C15, C20 as main component; drying; placing in the reactor; stirring; heating to 100-190 deg.c; adding 0.5-2.0% composition of anhydrous aluminium chloride as catalyst; polymerizing under 0-5Mpa for 10-35h to obtain rough resin; neutralizing rough resin; washing; sedimenting; decompressing; distilling.

Description

technical field [0001] The invention belongs to the field of chemical products, relates to a synthetic method of petroleum resin, in particular to a 10 、C 15 、C 20 A method of synthesizing petroleum resin with the mixed component as the main component as the raw material. Background technique [0002] Petroleum resin is produced by ethylene cracking by-product C 5 、C 9 Distillation is a chemical product obtained by polymerization of raw materials. C 5 Petroleum resin has excellent properties such as acid resistance, alkali resistance, and aging resistance, and is cheap, and can be widely used in adhesives, road marking paints, rubber additives, coatings, inks, etc. [0003] Petroleum resin is seldom used alone, usually mixed with other mixtures, it requires petroleum resin to have good compatibility, after being used in conjunction with other substances, it must have good water resistance, acid resistance, low melting point and good viscosity Compatibility. [0004] ...
