C9 heat polymerization type petroleum resin product with light color and high softening point and preparation process thereof

Abstract

The invention discloses a C9 heat polymerization type petroleum resin product with a light color and a high softening point and a preparation process thereof, and belongs to the technical field of petroleum resin preparation. The preparation method includes the following steps that C9 aromatic hydrocarbon fraction, which is a by-product of a cracking ethylene plant, serves as the main raw material, first the C9 raw material oil is subjected to rectification treatment to obtain a de-weighted C9 raw material; then, the de-weighted C9 raw material, dicyclopentadiene, methyldicyclopentadiene, indene, indane and the like are accurately weighed according to a certain proportional relationship, dissolved in a solvent oil and added into a thermal polymerization reactor, a the reaction initiator isadded, the mixture is stirred to be uniform, polymerization is carried out under a nitrogen atmosphere and normal pressure, the polymerized reactant is treated by a stripping device for recovering the solvent, and then the C9 heat polymerization type petroleum resin is obtained. According to the C9 heat polymerization type petroleum resin product with the light color and the high softening pointand the preparation process thereof, the C9 heat polymerization type petroleum resin suitable for the paint industry can be prepared by adjusting the contents of some components in the reaction materials and adding the reaction initiator.

Description

technical field

[0001] The invention belongs to the technical field of petroleum resin preparation, and in particular relates to a light-colored, high-softening point C9 thermally polymerized petroleum resin product and a preparation process. Background technique

[0002] C9 thermal polymer petroleum resin has good adhesiveness. In the paint and coating industry, petroleum resin can be mixed with other types of resins to partially or even completely replace high-cost resins. In this way, the quality can be reduced at the same time Cost, while improving the physical and chemical properties of the product such as water resistance, stability and chemical resistance. In the printing ink industry, petroleum resins have good compatibility with many components in printing inks, and for inks of different specifications, petroleum resins can meet their solvent release, water and alkali resistance, drying speed and wetting Speed ​​and other performance requirements, while the ink con...
