Embodiment 1

[0028] First, the C9 raw material is subjected to distillation treatment to remove 15% of the heavier components in the C9 raw material (accounting for the total mass of the C9 raw material). Then take respectively 1000g of C9 raw materials, 250g of dicyclopentadiene, 50g of methyl dicyclopentadiene, indene and indane 100g after deweighting treatment and dissolve it in 100g of mineral spirits; Initiator, then add the reaction materials into the thermal polymerization reactor and stir evenly, under the protection of nitrogen atmosphere and under normal pressure, the reaction temperature of the polymerization is controlled to be 240 °C, and the reaction time is controlled at 16h. After the reaction is completed, the polymerization reaction product is passed through After solvent oil is recovered by stripping, C9 thermal polymer petroleum resin is obtained. The measured Gardner color number of the resin is 10#, and the softening point is 135.2°C.

Embodiment 2

[0030]First, the C9 raw material is subjected to distillation treatment to remove 12% of the heavier components in the C9 raw material (accounting for the total mass of the C9 raw material). Then weigh the C9 raw material 800g, dicyclopentadiene 400g, methyl dicyclopentadiene 70g, indene and indane 130g and dissolve it in 100g mineral spirits respectively; Initiator, then add the reaction materials into the thermal polymerization reactor and stir evenly, under the protection of nitrogen atmosphere and under normal pressure, the reaction temperature of the polymerization is controlled at 245 °C, and the reaction time is controlled at 18h. After the reaction is completed, the polymerized reaction product is passed through After solvent oil is recovered by stripping, C9 thermal polymer petroleum resin is obtained. The measured Gardner color number of the resin is 12#, and the softening point is 140.3°C.

Embodiment 3

[0032] First, the C9 raw material is subjected to distillation treatment to remove 15% of the heavier components in the C9 raw material (accounting for the total mass of the C9 raw material). Then weigh the C9 raw material 1100g, dicyclopentadiene 100g, methyl dicyclopentadiene 100g, indene and indane 100g and dissolve it in 100g mineral spirits respectively; Then add the reaction materials into the thermal polymerization reactor and stir evenly. Under the protection of nitrogen atmosphere and under normal pressure, the reaction temperature of the polymerization is controlled at 240°C, and the reaction time is controlled at 12h. After the reaction is completed, the polymerization reaction product is passed through After solvent oil is recovered by stripping, C9 thermal polymer petroleum resin is obtained. The Gardner color number of the resin was measured to be 9#, and the softening point was 128.2°C.

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...
